Q: When you are replacing a water pump on a vehicle, should you replace the timing belt on the vehicle as well?: if the water pump is driven by the timing belt then its a good idea to change both as the labor to get into water pump is the same as to do the timing belt. I'd spend the extra $50 for the belts and change them while I'm in there and that way you'll be ahead of the game instead of paying (or taking the time) to do it twice at two different times

Q: I live in a condo building -- 3 floors, 7 units. In our storage units (right below my unit) is a water pump that was hooked up with the intent of helping the water flow to the 3rd floor. Everytime the pump goes off, it rattles, then makes a loud noise when it kicks off. The developers created a drywall box that houses the pump, which is surrounded by isolation, but it doesn't seem like it helps the noise. The pump also rattles the pipes that connect directly to the pump.My question is -- is this rattling normal for a standard water pump? If so, is there anything I can do to help cut down on the noise? If this is rattling is not normal of the standard water pump, what would it cost to replace it with something decent?: I do not know the kind of pump you are referring to. I will give my personal expertise. If it is a pump taking water from a tank, the piping might be loose, the knocking may be corrected with some air ventilation pipe. If it is pumping from a water tank: I suggest you look at a submersible pump capable of supplying water to 3rd floor. This kind of pump is less noisy. The noise at start, is the electric starter, and the noise at the end is when water returns and seals the stop valve. Also some air may be in the pipe, you need to purge the pump, as often as needed, try this first, and then the others. Good luck

Q: Stop the engine immediately and stop the circulating pump and the condensate pump. What's the harm to the turbine?: Stop the condensate pump is not required to condensate users, such as reducing water, mechanical seal water, shaft seal cooling water, deaerator, whether you need water. Stop circulating pump requires three: 1, exhaust steam temperature below 50. 2, there is no circulating water users. 3. No drain to condenser. If stop immediately stop circulating water and condensate pump, the consequences can be imagined.

Q: I need instructions on taking the old one out and replacing it with a new one. Photos will be helpful: Water Pump RemovalRemoval: Disconnect battery ground cable and drain coolant from engine. Loosen water pump idler pulley bolt and remove belt from water pump pulley. Remove water pump inlet tube. Remove three water pump retaining bolts and water pump, Fig. 16. Installation: Clean both gasket mating surfaces on water pump and cylinder block. Install three water pump retaining bolts and tighten to 20-30 N-m (15-22 ft-lbs). Connect water pump inlet tube on water pump. Install water pump belt on pulley and adjust tension to specification. Connect battery ground cable. Replace engine coolant. Operate engine until normal operating temperature is reached. Check for leaks and recheck coolant level. Couldn't get the picure but this should help, the pump is located on the backside of the engine, just be carefull, this engine is really easy to get the pulley on backwards then the belt won't line up right.

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.: I'm not telling you it all but you can take an A.C vacuum pump and it will lower the boiling point of the water where it will boil at only 65 to 75 degrees Ferlinghetti

Q: What do water pumps do on a car?: The water-pump circulates the hot coolant from the engine to the radiator where it is cooled and back to the water-pump through the hot engine again. If you had listed a particular car or truck as an example, some water-pumps push the hottest water in to the radiator through the lower radiator hose where it is cooled and then circulated back through the upper radiator hose to the cylinder-heads first then the block. This is the latest and greatest coolant circulation method because the cylinder-heads are the hottest part of a water-cooled internal combustion engine. The block temperature is always substantially cooler than the cylinder-heads. This is called a reverse cooled cooling system. One of these days to avoid confusion the makers of water-pumps should re-name them simply coolant pumps Race car engines are the only place real pure water is circulated through the cooling systems because antifreeze cuts cooling efficiency.

Q: Can someone please post a picture of how to find a Water Pump on a 1992 Dodge Spirit with a K2.5L Engine, it would be much appreciated. :): not a bad idea to post your question in the boating section, considering that us boaters are smarter than most, but you'll probably have a better chance of resolving your problem if you post it in the automotive repair section.

Q: Work done in water pumping?Water is to be brought from a well 60 meters bellow ground level to a tower 10 meters high, once there the water falls freely on a 5000 liter tank. A submerged pump 10 meters under water level and a two inch diameter pipe is to be used. What is the work done by the pump when 2000 liters have been served to the tank; what is the power of a pump selected to do this work in 20 minutes.: Power_W = (Mass_kg * Gravity_m/s/s * Height_m) / time_s Where: Mass kg is 1kg/l of 2000 liters Gravity is 9.81m/s/s Head is 60m + 10m (height). The suction head is ignored because the pump is submerged. In practice there is some suction head due to intake restrictions like pipes, check valves, strainers. The time is 20 minutes in seconds. The work is the energy used in the time allocated, which is: power * time in seconds, which is watt seconds = joules. Not needed here as it is in the formula above. Power is the rate of doing work. The depth below water is not really relevant except for pipe losses which increase the head slightly. The flow is 2000 liters/20 minutes = 100 l/min. This can be used with the head of 70m to determine the pipe restriction, which amounts to a pressure drop representing extra head added. It will indicate whether the pipe is too small (excessive head added) or whether the pipe is overkill (no head added). You can find on line calculators for this, e.g. search pipe resistance flow on line calculator. I am guessing a 2 inch pipe has little loss at this flow. This is the so called water power. It is the output power of the pump. The pump may only be 50% or so efficient, so the mechanical power delivered by the motor needs to be greater by this ratio. The electrical input power to the motor is greater again to allow for motor efficiency. This might be 60-90%. In practice the efficiency of pump and motor are determined from user manual or specification of the actual devices with the actual loads (head and flow).

Q: I want to know the disadvantages of a wind powered water pump and if you have any questions you would ask to someone presenting to you about a wind powered water pump(They should be really hard and smart questions) please include them in your answer.Thanks in advance.: The disadvantage is that it will not work with no wind. I would ask: 1. expected life 2. maintenance cost 3. capacity (liters/hour) at the mean wind speed on installation site 4. height it can pump the water (so that I can check the possibility of having a reservoir for the no wind period)

Q: Had house power washed today and need my water to work again!: I am assuming that the breaker for your water pump is in a disconnect box on the exterior of your house. If the disconnect is wired to code the disconnect would be fed with a line that also has breaker in your main panel. If this is the case the first thing you should do is identify this breaker and turn it off. Don't go by any labeling on the panel. Use a tester to make sure power is completely off in the disconnect.If power is off you can then pull the breaker out and dry it off. You can also dry the enclosure with a towel. When everything is dry reinstall the breaker and turn power back on in main panel. If it still pops in disconnect, it would be wise just to buy a new breaker , they are not that expensive. Not necessary to start using cleaning sprays.This procedure should solve your problem if everything has been wired to code. If you are not sure about anything I have described, please call a professional. Good luck.
