- Q:does anyone know how a water pump works????????????
- Water pumps are available in different types. 1. Centrifugal type: Operate by increasing the velocity of water which, when the velocity is decreased by the Volute casing, the pressure increases. 2. Rotary Gear type.: Operate by Displacement of the water by rotating, gears that trap water between the teeth of 2 rotors of inter-meshing gears that release the water at a higher pressure on the opposite side of the pump to the intake. 3. Piston (reciprocating) type: Also a displacement operation by a piston moving backwards and forwards within a cylinder (like a hypodermic syringe in operation). Back stroke takes water into the cylinder and forward stroke discharges it at a higher pressure. (Double acting types are also used that take in and discharge alternately from both ends). If you mean the water pump of your car, they are generally of the Rotary type.
- Q:Could someone tell me the procedure for removing & installing a water pump on 97 buick skylark 3.1L 3100 SFI?
- Water Pump Removal Disconnect negative battery cable. Drain cooling system. Remove air cleaner (if necessary). Loosen water pump pulley bolts. Remove serpentine drive belt. Remove water pump pulley bolts and pulley. Note position of locate tab on top of water pump for installation reference. Remove bolts, water pump and gasket. Installation Apply thread sealant to water pump bolts. To complete installation, reverse removal procedure. Fill and bleed cooling system (fill reservoir and radiator, run engine until upper rad hose starts to become hot. Top off and replace cap) Torque Specs Water pump bolt................89 Inch Pounds Water pump pulley bolt .....18 Foot Pounds
- Q:If a submersible pump to shake the insulation, water pump distance more than 20 meters away from the cable distribution box is fixed, at this time to shake the insulation in the distance distribution box can only shake, disconnect the power cable is connected with the shake table, the ground end is connected with the distribution box in such a shake, I want to ask is, what is this shake is not the pump shell must be reliable grounding to shake ah? Now the pump casing is not grounded, just immersed in water, immersed in the water, is not equal to good grounding ah?
- A submersible pump to shake the insulation, water pump distance more than 20 meters away from the cable distribution box is fixed, at this time to shake the insulation in the distance distribution box can only shake, disconnect the power cable is connected with the shake table, the ground end is connected with the electric box so that the pump shell shake shake, also must be reliable grounding to shake to now, the pump shell grounding not only in the water, it must be a wire connected with a shell or a wire will be immersed in water, this is right insulating shake,
- Q:toyota prius 2002 inverter water pump where is located and how to replace and buy
- Go okorder /
- Q:I think its the water pump, I fill the coolant with water everyday and it is empty once I make it to my destination.
- Call the shop where you are going to have the work done to get the cost as it varies by area and shop. You really should not be driving it if it's leaking that bad: You stand a chance of warping the head.
- Q:I just put a thermostat in my 92 chevy but the gauge still shows close to hot but go down to normal pretty fast and occasionally i her a loud sound coming from the area where the belt is but i can't pinpoint it. I replaced the pump about three years ago, could that be it again so soon?
- Take it to the local machanic shop
- Q:antifreeze leaking from the water pump. antifreeze wont stay in car, car overheating. 96 chevy cavalier. 2.4
- When the bearings go out it damages the seal, which allows coolant to leak from the weep hole. Change the pump ASAP. You don't want the fan going thru the radiator.
- Q:Theirs a house on a hill and a pond at the bottom of the hill what kind of pump can pull water 50ft up a hill?
- you could not, if that fifty feet is the vertical height. the optimal height a pump can suck water up is approximately 32 feet. that's constrained via the atmospheric tension and might't get replaced. One option is a pump on the backside interior the pond, pushing the water upwards. yet another is a jet pump, that may take a seat on the appropriate of the hill. It sends a jet of intense tension water all the way down to the pond, and that jet there pushes the water upwards. This must be primed, although. IF the 50 feet is in basic terms the slope distance up the hill, calculate or degree the vertical height, that's all that counts. .
- Q:can stress from to much weight cause the engine to get hot and cause your water pump to leak out the weep hole? and what else causes it to leak?
- WELL THERES ALOTE OF THINGS BUT THE MOST LIKELY IS MILES ALOTE OF MILES THEN THEY WILL FALL APART I FOUND BEING I WORK ON CARS THAT ABOUT EVERY 50,000 MILES CHANGE THE WATER PUMP AND YOU HAVE NO PROBLEMS
- Q:my marine engine doesnt pump water can you tell me some faults can be thanks vic
- There are 2 water pumps. One in the stern drive, or mounted on the engine which takes the water your in to cool the engine. The other is a conventional circulating water pump, which is important in fresh water cooled engines . Most often it's the impeller failure.
