Q:how does one prime a water pump connected to a lake?
Lake Water Pump
Q:What are the components of a water pump being used in a car and how does it work?
An automotive water pump consists of a steel shaft with an impeller (like a steamboat paddle wheel) on one end and a pulley flange on the other. The shaft spins on bearings located in a cast iron or aluminum housing. The housing has internal passages to allow the water to enter the impeller cavity and exit, often to a tube like structure (part of the housing casting) to which one of the rubber radiator hoses attaches. How it works is simple. Water present in the impeller cavity is confined and pushed to the outlet by the rotating vanes of the impeller. The rotation of the pump is usually driven by a belt powered by a pulley on the engine which turns a second pulley mounted to the pumps pulley flange. The characteristics might include things like, is the pump self priming or is it self lubricating? In an automotive system the answer to both questions is yes. To evaluate a pumps efficiency you would want to set up a test rig where you attach the pumps outlet to a long hose and use it to fill a calibrated container (one gallon, five gallons etc). Then with a stopwatch you can either time how long it takes to fill a gallon container or you can measure the volume of water pumped in a minute. Either way you will get useful information you can use to evaluate the pumps efficiency. You should repeat the above test at different engine RPM's to discover if the pump has peak efficiency (or lack of efficiency) at a particular RPM or range of RPM's. Finally, if you do this experiment for real be sure you add water as fast as you pump it out so you don't over heat the engine and damage it. Have fun.
Q:water pump leaking antifreeze?
Unfortunately, this usually requires a new pump. It's possible (but unlikely) that the gasket is leaking - more likely, the seal around the pulley shaft is the problem. Replacement is the only option. Usually, this is done at the same time as the timing belt - has this been done yet? If it was done before you got the car, its possible they tried to save a few bucks by skipping the water pump. This is usually a bad move - the pump almost always wears out at about the same time - but it is cheaper, if they were planning on getting rid of the car soon. And since one usually needs to be removed to access the other...you get the idea. Good luck!
Q:I have a water pump question?
Pressure testing requires a device that attaches to the top of your radiator which allows you to pump air into the system. This test will not always reveal a bad pump however. Find the weep hole (usually on the bottom of the water pump) and look for signs of leakage. If you see coolant you need a pump. Also grab the top of the fan and wiggle it if the belt pulley moves you need a pump.
Q:how is water pumped from deep wells?
water can't sucked up more than 10 M height in normal atmospheric pressure. This is why pressurized systems are used.
Q:Water pump fuse missing?
First no fuse for water pump only fuse and relay for rad. fan. First did you install serpentine belt correctly, should have diagram on rad. cover. If on right pump should work. if overheating could have bad thermostat or system needs bleeding, start, turn on heater and see if top hose on rad gets hot if not therm bad, replace, if hot look on top of thermostat housing for small bleeder screw crack open until coolant comes out then tighten,on some if there is a heater line on engine by radiator bleeder is on it. keep rad cap on till done, then remove slowly to release pressure and fill with coolant , GOOD luck.
Q:how do you change a water pump and on 2002 pontiac grand am gt?
This should be a V6 engine correct. if looking at front of engine,toward the belt , the water pump is located behind pulley appox. 5 inches on the side toward radiator. highest pulley on right side of engine. Replacement can be performed easily without many special tools.. First loosens each of the pulley bolts on pump. Then release tension on belt and route away from pulley. Remove remaining pulley bolts and pulley , Water pump has 5 bolts holding it to cover assembly, Mark-index the way pump installs and remove. Clean all gasket material. Install new pump and gasket, refill system and to open air blled on cooler pipe near water pump to allow air to escape.
Q:1 water pump frequency converter constant pressure water supply wiring diagram
Light can not be seen in this picture, but also need to see the definition of the terminal on the practical manual, generally speaking, the three terminals are connected to +10V, public and analog signals / multi-function terminals.
Q:what's wrong with my water pump?
what the hell are you working on?? Need just a little more input
Q:changing the water pump in my car?
The water pump on that vehicle is a ob-centric style that you rotate to create belt tension. This is a bit tricky and some people have broken the pump trying to tighten the belt so be careful. Look at the replacement pump carefully before you attempt to change it, this will give you clues as to how it works.
