What does the phrase "pump the brakes" mean exactly? I'm no expert on cars and I'm not quite sure what it means. Does it mean to slow down or slow down abruptly or something like that? Thanks a lot! Here's the excerpt (from the show Roseanne) Uh-huh, right. That's why you throw me all over the car pumpin' those brakes. I pump the brakes to make sure they grab. If they don't grab, I rear end the guy in front of me, I get a ticket, they raise our insurance premiums, we go broke trying to pay 'em, we end up in the poor horse.... Edit: Or can it mean that you remove air from the brakes or something? Pumping the breaks is the repeated pushing down on the break pedal, releasing it, then pushing it down again. Pumping the breaks is the repeated pushing down on the break pedal, releasing it, then pushing it down again. Okay, thanks. But what is the point? To slow down or to remove air? It can be to avoid their overheating, or to get a sense of the braking power needed. In this case our hero says he does it to make sure they grab; he seems to think, and he may be right, that they lose effect if held down for long. My friend used to have a really old van, that was until the motor fell out of it (and that's literally), and he'd have to repeatedly push down and lift up on the breaks or it wouldn't stop. Okay, thanks, everyone. Just to make sure: The meaning here is that Dan is pushing the brake pedal repeatedly while driving (for some reason) and NOT letting the air out from the brakes intentionally. Or both? Okay, thanks, everyone. Just to make sure: The meaning here is that Dan is pushing the brake pedal repeatedly while driving (for some reason) and NOT letting the air out from the brakes intentionally. Or both? What makes you think he's got air in his brakes, Subtitler? I was Continue reading >>

Rapper Lil Pump Arrested For Firing A Gun In His Home

Rapper Lil Pump Arrested For Firing A Gun In His Home

Rapper Lil Pump arrested for firing a gun in his home Lil Pump was reportedly arrested Wednesday. (Jared Siskin/Getty Images for Warner Music Group) "Gucci Gang" rapper Lil Pump was arrested Wednesday for firing a gun in his California home after police determined his story of a would-be break-in was bogus. Pump whose real name is Gazzy Garcia called police and alleged three black men had tried to break into his San Fernando Valley home and that the would-be trespassers fired a single shot through the front door, the LAPD said. Police were "immediately suspicious" about Pump's story, and said they arrived on the scene around 4:20 p.m. to find that the door's lone bullet hole came from inside the home, not outside as the rapper had claimed. The Miami-born star was arrested for illegal discharge of a firearm after police, on a search warrant, found a handgun in the bushes outside the apartment. Officers also found marijuana in the home, and are considering placing Pump's mother under investigation for endangering a minor and having an unsecured gun at home. She was not present at the time of the incident. Continue reading >>

View Details MAKE SURE THAT YOU ARE UP TO DATE AND IN THE KNOW WITH THE MELDON LAW TALK NEWSLETTER View Details This is an excellent road safety question and one that many people are confused about. Most vehicles are equipped with Antilock Brake Systems (ABS), however, that wasnt always the case. Many of us learned to drive without the assistance of ABS and therefore, we learned that in times of emergencies when you have to slam on your brakes you must pump the brakes to keep them from locking up which results in skidding and loss of control of the vehicle. In short, ABS adds an extra layer of safety to your vehicles brakes which, when used properly, prevents skidding and reduces stopping distance during hard braking on wet and icy streets. However, if you are not using the ABS properly, you will not be getting its benefits. The main purpose of ABS it to prevent your brakes from locking up resulting in loss of control at times when you must stop quickly. Essentially, the system pumps the brakes automatically for you, preventing them from locking up. You do not have to pump your brakes. In fact, if you pump them while braking hard, you will lose the benefits of the ABS. During emergency hard braking, apply firm pressure to the brake pedal; do not take your foot off t Continue reading >>

25 Ways To Break A Pump

25 Ways To Break A Pump

Adam.Bristow 2018-02-12T16:26:59+00:00 March 12th, 2015| Over our 40+ years of processing harsh and acidic chemicals, weve seen our fair share of pumps that have been broken due to mismanagement and misinformation. Take a look through our guide of 25 ways to break a pump and see if your business is making the same mistakes: Relying on Reactive Maintenance rather than Predictive Measures Too many times pump maintenance is overlooked or forgotten about within the maintenance procedures, leaning to only reactive maintenance if the pumps fails, leading to longer process down time, pump instability and expensive repairs. Instead, schedule biannually or quarterly pump maintenance including inlet cleaning, corrosion inspection, vibration monitoring and heat maintenance at the very least to ensure thatcavitation or bearing wear is avoided. Every time a bearing is replaced, or the shaft is cleaned, just a tiny fraction of the material on the surface is removed. Over time, a little adds up to a lot and can really affect the bearing clearance on the shaft. When this happens, expect the bearings to spin within the housing, or on the shaft. Lack of knowledge accounts for the majority of mechanical seal failures. Incorrect mechanical seal installation can lead to seal face damage, heat escalation and ultimately pump failure. Make sure you discuss thoroughly the type of chemicals you are processing with the pump manufacturer and type of mechanical seal you need. The pump should be eased into pumping with a soft start. With a hard start, the pump tries to pump liquid as soon as it powers on. The pressure inside the pump causes the shaft to deflect towards the low pressure side causing the shaft to contact the casing. The misalignment will then cause seal failure. Remember to keep the Continue reading >>

Recurring Wire Breaking On Well Pump

Recurring Wire Breaking On Well Pump

Terry Love Plumbing & Remodel DIY & Professional Forum My well is about 250 feet deep on black flexible pipe in rock with a casing extending the first fifty feet or so. The pump lasted for about twenty years with no problems except for having to replace a check valve and bladder tank about ten years ago. In 2011 I began doing a fair amount of irrigation--running about 6 to 8 GPM for several hours per day during droughts in 2011 and 2012, and less so far this year. We finally had to replace the pump with a 1 HP Flint Walling pump in June, 2011. Then in June, 2012 we had to have the pump pulled to replace the wiring. Had to do that again just a month later and then again last week. The wire was chafed about ten feet above the pump. I asked the pump man about using a torque suppressor or the plastic wire guards or even placing some poly pipe over the lower part of the wire, and he said none of those worked in his experience. I'm guessing that the irrigation causes the pump to cycle more often than normal, which may partially account for the excessive wear on the wiring, but I need to try to come up with a fix. I have seen a lot of opinions on the torque suppressors and cable guards, and I don't expect to see any consensus on those, but it does seem that reducing the cycling would surely help. I thought about installing a much larger tank with a separate pump, but that would probably get expensive. Since the last event I have done some more reading and have read that a CSV (Cycle Stop Valve) might be an option. I guess this would reduce the number of cycles, but I worry that reducing the flow rate might hinder the cooling of the motor. Any opinions on either CSV valves or other options would be appreciated. There are lots of reasons wire rubs....crooked hole, rough rock ed Continue reading >>

Cadence Braking - Wikipedia

Cadence Braking - Wikipedia

Cadence braking or stutter braking is a driving technique that involves pumping the brake pedal and is used to allow a car to both steer and brake on a slippery surface. It is used to effect an emergency stop where traction is limited to reduce the effect of skidding from road wheels locking up under braking. This can be a particular problem when different tires have different traction, such as on patchy ice for example. Its use in an emergency requires a presence of mind that the situation itself might preclude. Cadence braking is supposed to maximize the time for the driver to steer around the obstacle ahead, as it allows the driver to steer while slowing. It needs to be learned and practiced. For most drivers of modern cars, it has been entirely superseded by ABS , however it is still a valuable skill for drivers of non-ABS equipped vehicles such as classic cars or economy cars . Maximum braking force is obtained when there is approximately 1020% slippage between the braked wheel's rotational speed and the road surface. [1] Beyond this point, rolling grip diminishes rapidly and sliding friction provides a greater proportion of the force that slows the vehicle. Due to local heating and melting of the tyres , the sliding friction can be very low. When braking at, or beyond, the peak braking force the steering is ineffective since the grip of the tyre is entirely consumed in braking the vehicle. Anti-lock braking system performs these operations automatically many times per second in rapid succession. A human driver can perform one lock-release cycle per second with practice[ dubious discuss ][ citation needed ]. This is done primarily to maintain steering control, at least in part. In wet, hard surfaces, this is useful to reduce somewhat total braking distance. When A Continue reading >>

The Art Of The Insulin Pump Break

The Art Of The Insulin Pump Break

There are times when I just want to be pump free for a weekend. I think most people with diabetes that wear a device or two relish a day without a plastic and metal device stuck to their skin. Aside from not having to deal with any questions or looks, it justfeelsgood.Although we get used to our gear, it doesnt mean we dont like a little break now and then. For me, living in Southern California, summer weekends can mean lots of time in a bathing suit, which are the times when Im most tempted to take a day off from the hardware (I actually have a CGM sensor tanline right now from a few weekends ago. My dermatologist busted up laughing when he saw the oval shape on my hip. Then he chided me for not using sunscreen. Hes right. Digression). Although we are lucky enough to live in a time where we even have theoptionof taking a break, Ive found that going back to a basal-bolus regimen of multiple daily injections (MDI) is tougher than it sounds. Youd think you just take a shot of Lantus, remove your pump, and voila, inject your rapid-acting as needed. No dice. For one thing, I was on a split dose of Lantus before my pump. Although it claims 24 hour control, I did better when I took half the Lantus I needed for a full day in the morning, the other half at night. But, if youre only taking a 24 hour pump break, it doesnt make sense to split the dose because then youre actually dealing with some varying amount of Lantus on board for 36 hours which is a pain to regulate when you put a pump back on. So, when I take a pump break, I usually just do one full dose of Lantus for a 24 hour period, which doesnt seem to cover me as well. The other issue with going back to injections is that Ive gotten so used to being able to take doses as small as one-tenth of a unit with my pump. I find Continue reading >>

Why Centrifugal Pumps Break Shafts And How To Prevent It

Why Centrifugal Pumps Break Shafts And How To Prevent It

Why centrifugal pumps break shafts and how to prevent it Vertical Turbine Pumps - Advice on buying and installing Though most people who have operated centrifugal pumps are familiar with the problem of broken shafts, few understand the reasons behind why the shafts break. Thus the problem continues... But it doesnt have to. Learning why the shafts break can help you prevent the damage from happening. First, pump shafts break because: they twist, they bend, and they they wear out. Calculate the diameter of shaft required to carry the maximum horsepower that any particular centrifugal pump could draw. Then add in a generous safety factor for shock loading which wont really happen unless you have a jammed pump. You will most likely come up with a shaft diameter that is about one-half of that used in the pump! Most pump shafts are designed on some other basis. You may also deduce that you have never broken a pump shaft by simply twisting it until it breaks off. You can bend the shaft until it breaks though not inside any centrifugal pump weve ever seen. There isnt enough room to bend the shaft that far. But the key here is inside the pump. Its possible to misalign the pump and driver and break the shaft on either side of the outboard bearing. Though this has happened, its more likely that the bearings fail before the shaft. So if you have shaft breakage near the bearings, misalignment is probably the culprit. Shafts can wear out. This is the cause of the vast majority of centrifugal pump shaft breakage. Conventional wisdom notes that stresses far below the ultimate strength of the shaft if repeated enough will cause the shaft to break. But not always. If the stress is low enough, it can be repeated infinitely without causing damage. For example, you could bend a pump shaft Continue reading >>

What Does It Mean To

What Does It Mean To "pump" Your Breaks?

"Its refering to traction control. If u just hit ur brakes normaly then u still can maintain control of the wheels. If u pump ur brakes u lose control of the wheels . Example: ur driving and suddenly the person n front of u slams on the brakes. If u hit ur brakes normaly then u can still manuever ur vehical around the one n front of u avoiding an accident. If u hit them then take ur foot off and hit them again u cant turn ur car at all and BAM! U hit the car n front of u.." When you don't lose control of steering when you pump your breaks, you might get less control though. When you pump your breaks what happens is that all four breaks on your car work at the same pressure. However in newer cars with ABS and just press the breaks like normal, it just keeps your wheels from locking which you don't want and also slows your car in a much more efficient manner "Pumping the brakes is a technique that is sometimes used in slippery conditions to allow the wheels to unlock so that the vehicle stays somewhat straight during a stop. In a car with ABS the wheels should never lock in the first place, so pumping the brakes will just make you take longer to stop. " In the days before Antilock Brake Systems (ABS) when you were under heavy braking the tires would lock up. By doing so, this would cause the tire to skid... show more In the days before Antilock Brake Systems (ABS) when you were under heavy braking the tires would lock up. By doing so, this would cause the tire to skid across the traction surface and produce much less stopping power. The driver would "pump the brakes" to prevent the skid. Your ABS system senses the skid for you, and pulses the brake pressure based on a computer s reaction to that skid, allowing the tire to regain traction. This is the buzzing feeling in y Continue reading >>

Breaking The Cycle Of Pump Repairs: Part 3 Of 4

Breaking The Cycle Of Pump Repairs: Part 3 Of 4

Breaking The Cycle of Pump Repairs: Part 3 of 4 The traditional oil sump was depicted, in figure 5 (see earlier Part 2 of this series, Insist on Better Pumps, Modern Pumping Today, February 2013: 30), with the lubricant reaching to about the center of the lowermost bearing elements. This arrangement works well at low shaft surface velocities. To gain reliability advantages, synthetic lubricants, oil mist application (called oil fog in some languages), and liquid-oil jets (also known as oil spray) are often used. Oil jets are well described in references 1 through 6 and should not be confused with oil mist. But circulating systems also merit consideration in certain high-load or very large pumping services. Generally speaking, circulating systems are selected for large pumps utilizing sleeve bearings. In these systems, the oil can be passed through a heat exchanger before being returned to the bearing. However, regardless of lube application method on rolling element bearings, cooling will not be needed as long as high-grade mineral or synthetic lubricants are utilized (see reference 3). High-performance mineral oils developed around 2012 are deliberately mentioned here. Irrespective of base stock and oil formulation, the required lubricant viscosity is a function of bearing diameter and shaft speed. Technical reasons are described in numerous books and articles, among them references 7 and 8. Most process pump bearings will reach long operating lives if the oil viscosity (at a particular operating temperature) is maintained in a range from 13 to 20 cSt (see references 3 and 7). It should be noted that whenever oil rings are used to lift the oil from sump to bearings, the need to maintain a narrow range of viscosities takes on added importance. In the special case of th Continue reading >>

How Do You Solve A Problem Like A Broken Water Pump?

How do you solve a problem like a broken water pump? Long considered a symbol of development aid, up to 40% of handpumps in sub-Saharan Africa are broken at any one time. Technology is offering smart solutions Last modified on Wed 14 Feb 2018 11.38EST It is estimated that 60,000 handpumps are installed in sub-Saharan Africa every year, yet 30 to 40% do not work at any one time.Photograph: Pascal Guyot/AFP/Getty Images Over the past few decades, the humble handpump has become the go-to option for rural water supply in developing countries. Theyre used to extract groundwater which is mostly clean, easy and cheap to access, and available year-round. Handpumps are usually a better option than open wells which are highly vulnerable to contamination and piped schemes or motorised pumps, which require the skills, finances, and management thats often lacking in remote, rural areas. However, though around 60,000 handpumps (pdf) are installed across sub-Saharan Africa every year, typically 30 to 40% of those in the region do not work at any one time, according to estimates made by the Rural Water Supply Network. More often than not, broken handpumps are abandoned and fall into disuse. The World Bank has estimated that over the last 20 years this represents a loss of investment of more than $1.2bn (pdf). The ATMs bringing cheap, safe water to Nairobi's slums Water points can fail for a number of reasons. First, most handpumps are manufactured in India where quality controls are not always enforced and poor-grade recycled metal is used, meaning parts break more easily. Second, and most commonly, handpumps stop working because the borehole it extracts groundwater through was drilled in the wrong place or in the wrong way. Not enough data about the land or geology contributes to thi Continue reading >>

Blog Post | To Pump Or Not To Pump The Brakes | Car Talk

Blog Post | To Pump Or Not To Pump The Brakes | Car Talk

I need help in convincing my wife that she doesn't need to "pump" the brakes when coming to a stop on dry pavement. It really jerks the unsuspecting passenger around. It seems a guy she knew in high school told her that the brakes would last longer if she pumped them. The reasoning being that the wear would be spread over more of the brake surface, rather than in one spot. I feel this is faulty reasoning. Furthermore, even if there is any truth to it, I don't care. I'd rather have a little wear and tear on the brakes than get thrown around every time we come to a stop. Please help with your comments. This has been going on for 16 years! RAY: Well, first of all Chuck, I think it's time you dropped this grudge against your wife's former high school boyfriend. You've been married to her for 16 years, so I think it's clear who won that one. TOM: But you're absolutely right. Your wife is not preventing any wear and tear by pumping the brakes. The wheels are turning when you use the brakes, so the wear and tear is automatically spread evenly over the surfaces of the disc rotors and drums. Even more so than if you pump the pedal! RAY: To be fair to this knucklehead high school boyfriend, there are some situations in which you might want to pump the brakes. If you were driving down a very long, steep hill, you might pump the brakes to keep them from overheating. TOM: But even then, you would "pump" the brakes by applying them lightly for five or ten seconds, then releasing them. You wouldn't "jab" at them so that the passenger gets a flat spot on his forehead from banging against the dashboard. RAY: And on wet pavement, ice, or snow, pumping the brakes can keep them from locking up. That's a crude (and not very accurate) attempt at doing what anti-lock brakes do automatically.

7 Reasons Centrifugal Pump Shafts Break

7 Reasons Centrifugal Pump Shafts Break

The twisting, the bending, and finally the snap. I'm not talking about the end result of my all-too-infrequent workouts, I'm talking about centrifugal pump shaft breakage. To find out what causes centrifugalpump shafts to break, I took a walk to our Service Center and spoke with one of our longest tenured and most experienced service technicians. He shared 7 ways this happens. Metallurgical/Manufacturing Process Flaws Occasionally there are flaws in the metal or manufacturing process that can cause shafts to fail prematurely. When a pump shaftbreaks, the natural reaction is to blame the manufacturer. But in reality, shaft breakage is more often a direct result of the pump's operating conditions. Only a very small percentage of shaft failures are due to manufacturing flaws. Vibration is most commonly caused by cavitation, critical speed, passing vane frequency, and operating outside the pump's best efficiency point. Pump bearings begin wear, allowing the shaft to move laterally, causing the shaft to flex and eventuallyfail.The vibration harmonics also puts extra stress on the pump shaft. Imbalance creates problems while the pump is running, though the shaft will measure straight if stopped. It's a source of vibration and will reduce machine, bearing, and mechanical seal life. Poor installation , pipe strain , extreme belt tension and sheave misalignment on direct drive pumps all put undue stress on a pump's bearings and shaft. Note, in a misalignment scenario, the pump's bearings are more likely to fail before the shaft does. Nonetheless, because misalignment creates bending moments for the shaft, weakening it over time, we've included it here. When a pump is selected to move lower viscosity fluids, but subjected to higher viscosity fluids, likelihood of shaft breakage Continue reading >>

How To Tell If A Fuel Pump Is Bad

How To Tell If A Fuel Pump Is Bad

It is a simple fact of life that if the fuel pump stops working the car will stop moving. It is the fuel pump that sees to it that gasoline gets from the tank to the engine. While it is possible to run on a failing fuel pump for a certain distance it will sooner or later no longer operate. This can leave you stranded by the side of the road. It is something that no one wants to have happen. If you are alert to possible signs of the fuel pump going bad , you can spare yourself the trouble of the car breaking down and you having to pay towing costs. One of the best indicators of a failing fuel pump is found on the open road. If a car is moving at an accelerated speed, perhaps above 50 miles an hour, and the vehicle starts jerking and then resumes regular performance, it might not be a bad spark plug. There may be something wrong with the fuel pump. Another signal of trouble may be at the gas station. If the car ordinarily is good on gasoline, and then suddenly becomes a gas hog, there could be an emergency under the hood. Fuel pumps have a relief valve. Should for any reason that relief valves not open, then more fuel than necessary is going go into the engine system. Besides raising cost at the pump, it can result in the engine being flooded with too much gasoline. The temperature of the car can also telegraph an emergency with the fuel pump. If the heat rises and the car stalls, this may be an indication that the motor of the fuel pump is having problems. Attempting to start the car again, only to have it stall once more, makes it clear that there is some difficulty with the fuel pump. Not being able to start the car at all can be a sign of that essential auto part starting to deteriorate . That a fuel pump is starting to go bad may not be the fault of the owner at all Continue reading >>
