Q: When you are replacing a water pump on a vehicle, should you replace the timing belt on the vehicle as well?
It depends on the make of the car. Some Hondas and Meesoshitties require replacement of the timing belt whenever it is removed due to stress factors and crap. So it is always a good idea to go ahead and do since on a lot of front wheel drive cars you will have everything off in front of the timing belt anyways. So might as well do it right? Better that than end up on the freeway with a snapped timing belt. Not fun.
Q: Pump suction and pressure side road why should vacuum table and pressure gauge, and what role they have?
The pump suction and pressure side roads shall be equipped with a vacuum meter and a pressure gauge to monitor the operation of the system. When the pump is running, if the suction side of the vacuum decreases, indicating that the performance of water pump or water absorption pipe leakage; if the vacuum increases, it may be blocked suction pipe. The pressure on the water side is too large. It may be less water or the water pipe is blocked. If the pressure drops, the water consumption may increase or the water pump performance will decrease.The pressure gauges on the water side also play an important role in observing the pressure changes at the start of the pump to determine when to open the outlet valve. Usually larger pump starts, should first close the outlet valve to reduce the starting current, until the pressure of the pump rising and stable, then open the outlet valve.
Q: What is the difference between a High Flow Water Pump, Heavy Duty Water Pump or and Electrical Water Pump for a street rod? I have a 77 Camaro with around 410hp with the factory A/C. The Camaro is stock as body, frame and interior. I want to enjoy the car vs racing it. I would like to go on trips to visit family out of town which is around 300 miles and be able to drive the car with out having over heating problems.
High flow is just that. It flows more coolant than stock Heavy duty is one with alittle bigger impeller shaft and disk Elec. water pump runs on 12 volts, no belt You should not use an elec water pump on a street car, those flows less coolant and do not last as long. I recommed a Milidon high flow water pump for yours. I'm running one of those, a summit 31x19 alum rad, and a ford turus 2 speed elec. fan on a 500 HP engine in a camaro and never have any cooling probs.. Even on 6 hour one way non stop trip in 90-100* weather during the summer
Q: how can i put in a water pump for a1994 bonniville sse?

Q: Colleagues, could you explain the principles of operation of the water vane vacuum pump? What range of pressure can one achieve with this type of vacuum pump? If somebody could post a reference to books, app notes, commercial datasheets of such pumps, that would be simply great.
*Correctly said by Mr.Pete. I think you are asking about water ring vacuum pump. Basically it is a liquid ring vacuum pump. *A liquid ring pump is a rotating positive displacement pump. They are typically used as a vacuum pump but can also be used as a gas compressor. The function of a liquid ring pump is similar to a rotary vane pump the difference being that the vanes are an integral part of the rotor and churn a rotating ring of liquid to form the compression chamber seal. They are an inherently low friction design, with the rotor being the only moving part. Sliding friction is limited to the shaft seals. Liquid ring pumps are typically powered by an induction motor. *Single stage vacuum pumps typically produce vacuum to 35 torr (mm Hg) or 0.047 bar, and two-stage pumps can produce vacuum to 25 torr (mmHgA), assuming air is being pumped and the ring-liquid is water at 15°C (60F) or less. Dry air and 15°C sealant water temperature is the standard performance basis which most manufacturers use for their performance curves. *You have to take negative pressure if you are talking about pressure. Negative gauge pressure, a way of expressing pressure measurements below atmospheric pressure.
Q: my pump went out and i can't afford to have it fixed at a shop.
then buy a new one and get your self some tools and a repair manual at autoparts store not much to it once you see what it looks like you start removing parts that are in way til you can take it off clean the old gasket off well and but some blue selicone put on new gasket and put on new pump tighten it put back on all the parts you remove fill radiator start check for leaks should be able to do it on the weekend about three to four hours or lless... any of these will help all about the same as the other but it will give you a better ideal of how to do it and your sure to learn more about your car so doing it would be best not only you learn but you save money too... not hard to replace most parts hard part is knowing what is wrong to replace it so you got the hard part done knowing what is wrong
Q: need step by step on how to change water pump

Q: A tank is full of water. Find the work W required to pump the water out of the spout. (Use 9.8 for g and 3.14 for pi . Round your answer to three significant digits.)The tank is a spherical shape has a radius r= 6m and a spout height of h=2m.I really dont know how to start this problem correctly. Any help will be appreciated. Thanks!
The pump will not have to work until the water drains by gravity to the level of the spout. Then, Work = Weight of water * Height of lift Find the distance, d, of the center of mass for the remaining water in the bottom 2 m of the sphere. The height of lift will then be 2m - d. The hardest part is finding the distance d to the center of mass. I don't remember how to do that.
Q: If you use a water pump to move water through a circular trench, essentially making a little river, and then place some kind of turbine or water wheel or something to generate electricity from the moving water, couldn't you use the electricity generated by the turbine to power the pump, thus requiring no outside power?
All the energy that you can get from the stream you have created will always be less than the one you are using to drive the pump that feeds the stream. In engineering field you must get into your brain that Perpetual. motion machines just does not exist. you can use it to understant thermodynamics processes when using in simulated problems but it is only ideal situations.
Q: overheating.it has a new thermostat,radiator is clean.temp stays normal during idle,rises when i start to drive.ac is off when this happens.its a 4.7 dodge durango.can water pump simplyquot;go badquot;without ever leaking?
The short answer to your question: It is unlikely that a water pump will go bad without leaking, but weirder things have happened. Your thinking is right overheating only when you drive is an indication of limited flow, either caused by a restriction (radiator, hose, thermostat), an air bubble, or a bad pump. Are you sure that the air is bled out of your system? If you have an air pocket in your engine or at the pump, you will get reduced flow. I think that the 4.7 Durango has a radiator cap, if so, with the engine cold, take the cap off, fill it, and start the engine. If you get bubbles every time you rev the engine, then you may have a bad head gasket, this would introduce bubbles in the system... Make sure that the lower radiator hose is not collapsing. Most of these hoses have a stiff spring inside to keep them from collapsing when the water pump is running. Otherwise, my guess would be that your pump is bad, or you have more restrictions in your system. Good luck.
