Q: What is the function of the pump?: Pumps are usually used to enhance the liquid, conveying a liquid or liquid to increase the pressure, that is the original motive of the mechanical energy so as to achieve variable liquid fluid energy machine called pump.The technical parameters of measuring water pump include flow, suction, lift, shaft power, water power, efficiency, etc. according to different working principles, they can be divided into volumetric pump, vane pump and so on. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.

Q: What is the current of the pump when it is started?: Just started when the pump current is 2-3 times the rated current is normal, so, the power is greater than the pump motor, many small factories in order to survive, the small motor will cut corners, produces motor burning phenomenon, and pump failure caused by load current is increased, and the pump flow rate exceeds the rated flow is a super current. General large water pump is the first to start the water pump, and then open the outlet valve, is to solve the pump just started when the ultra current problems.After excluding pump fault flowmeter check flow is beyond the rated flow, the excess can pumpslittle off flow control valve to reduce the current problems above are not dismantle the motor current of the motor itself over to see how to judge whether the motor has fault.

Q: Hello, i have a 1987 volkswagen cabriolet that i purchased earlier this year. So far its been a pain in the butt. Recently i noticed it overheats real quick, but it didnt use to. then i noticed the coolant/antifreeze was being used up like no other! I discovered, after being parked at work, that it was leaking.it leaks basically anything i put in there now!! it leaks from the water pump housing,.,.... at least thats what the internet said it was.. its leaking from the end of the hose that connects to the engine... (the hose that comes from the coolant reservoir.)What do i do? I dont feel any cracks? does this part crack? is it an o-ring or somehting? I am really absolutely NOTHING ABOUT CARS. Please help!!: Water pumps have a seal to hold the water from leaking out the spinning shaft, and the seal always wears out about every 100,000 miles. It is probably this seal that is bad, because it is probably the original pump, and you replace the whole pump. You have to take the front belt cover off and remove the timing belt, so it is not a trivial job. Cost about $300, and takes about 2 hours. But any friend who understands timing belts can do it easily. No special tools or tricks involved, other than making sure the cam timing is correct. Once you take the 3 bolts holding the water pump housing off, you can easily tell if any hoses or clamps should also be replaced. Do the thermostat while you have it off anyway. It is only $5.

Q: There is a pump, the rated power is 1200W, but only more than 600 W measured!What's the matter, please?I was not measuring no-load, pumping water in the pool, this work environment should be sufficient to pump full load?Also, is the rated power should not change?Thank you: Not equal to.1. Calculate the shaft power of centrifugal pump:Pa = HQ P /102 KWType H - pump rated lift, m;Q - rated flow of the pump, m3/s;P -- medium density, /m3 kg;Efficiency -- pump rated conditions (ETA = ETA ETA ETA m h V, m -- h -- mechanical efficiency, hydraulic efficiency,ETA V - volume efficiency);Pa - shaft power under rated working condition of pump, KW.2, determine the motor powerP=KPa/.Among them, P--- motors are equipped with powerShaft power under rated condition of Pa-- pumpETA - pump drive efficiency, general pump is using direct drive 1.K-- original motive power margin coefficient (shaft power less than 15KW, 1.25; 15 Pa > 55KW, 55KW > 1.15;, 1.1)

Q: Where is the water pump?How do i take it out, and replace it?: Drain Cooling System. Remove right front lower fender shield. Loosen pump pulley bolts Remove Accessory Drive Belt. Remove pump pulley bolts and remove pulley. Remove pump mounting screws Remove pump. Remove and discard O-ring seal. Clean O-ring groove and O-ring surfaces on pump and chain case cover. Take care not to scratch or gouge sealing surface. Reassemble in the opposite order. This will be a good time to replace your thermostat and check all hoses for wear and leaks.

Q: When my wife was driving on freeway, the alternator belt broke and battery sign showed up. She also told that the temperature gauze showed high. Luckily she reached home with the battery fully charged. When I checked under hood, there was coolant spill surrounding water pump . I could not figure out where the coolant came from. Overnight parking did not show any further leakage of coolant. is there a need to change the water pump also.: For one thing. Once the belt breaks your battery light will come on because the alternator can't charge the battery anymore and also your car will overheat if you have a serpentine belt because once the belt is broke nothing will move anymore including your water pump. Your leak probably came from the overflow tank which is normal when a car overheats. You don't seem to know much about cars so I assume that you really don't know where the water pump is. Change the belt and than hope to god that she didn't run the car to long while it was hot to crack the head gasket . oh and make sure you add enough coolant back to the cooling system before you start the car again

Q: One mechanic told me that my Toyota Corolla 2004 CE's water pump is leaking and I need to change pump and its belt costing me around $450. I took it to other mechanic today and he told that water pump looks good and no need to worry. I need to know how I can verify that water pump is leaking or not. Below are some facts of the car that I noticed myself.1. The engine collant level is above half level about at 70% 2. I started my car around 8.30 PM @ 90 degree F after break of 3 hours and the temprature gauge reach to half in 5 minutes.Please advice what can be done to determine the leak is there or not else I have to take it to other mechanic.: Toyota Corolla Water Pump

Q: how much would they charge me to change a water pump on my 1999 cadillac deville: They always change the water pump and timing belt together while the engine is apart. Your 1999 is probably due for both things if they have not been done. I just had mine done on a Toyota Camry. It cost a thousand dollars. Remember that these two things NEED to be changed every so often..if either the water pump, or timing belt go while you are driving..your car will die right there on the freeway...even if you are going 80 MPH.

Q: How much solar energy would you need to generate and run a small water pump? Say one that is big enough to extract water from a bucket that is 1 ft wide x 2 ft deep? What size solar panel would you need to accomplish this?: The key is, as 96sentra says, where does the water have to go. We would need to know how high above bucket (minimum) water level will the other end of the hose be, and how fast (Liter or gallon per minute) shall the water flow. This determines the pump type, which in turn determines the solar panel size.

Q: we changed the water pump it went bad and there is still a knock in it please help it is running really sluggish: Have your radiator checked, replace the radiator cap and thermostate, look at all your hoses and you should be just fine,, 2002M7
