Q: i need to know how the water pumps, how it transports, where it goes, and how the structure is used to control the direction of the flow. Please help? I'd really like to know., thank you in advance!: you're saying that your pump used to function precise in the previous, so if the pump is in sturdy situation, the elevate should not be too great so we are able to rule that out. it sounds as though to me that the gurgling sound may well be made by potential of sucking air, and for this to ensue, it would be a concern on the inlet area of the pump. If the guy who repaired the pump is familiar with what he's doing, it won't be the pump, so we are able to rule that out. That leaves the pipe and any fittings between the pump and the foot valve that could desire to be on the top of the pipe. attempt working the pump, and pouring water over all joints and fittings, one after the different, if the pump is working precise, a slurping sound would be heard on the leak. The pump could have a priming factor, a screw in plug, someplace on proper of it. With the pump stopped, get rid of the plug, and pour water into the hollow. you will possibly desire to have the skill to fill the pump appropriate up, and the water stay at that time, without draining away. If it wont hold the water, the valve on the backside of the pipe is the two wiped out or has something like a stone or gravel struggling with it from working precise. As you have disconnected this pump for upkeep, it would have needed priming besides, that's the filling up with water. it is too plenty to ask a dry pump to enhance water any peak, so in step with danger you do not have a concern in any respect. sturdy success

Q: i took off the lower unit to fix the gears. im not sure ill be able to put it back on with out knowing how things work in there.so how exactly does the water get pumped. and what does it have to do with the gears, because even though the prop wasn't turning, the water was still pumping.thanks.: The drive shaft turns with the engine and turns the impeller which picks up water and pushes it into the power head and exhaust There is a pick up in the foot

Q: I'm just wondering where I should buy my new water pump for my 2.2 cavalier? Auto zone, carquest, checker? Does it matter which one?Thanks: They all buy their water pumps from the same manufacturer. Beware !!! Don't trust the location of the weep hole from the original pump to line up the replacement. Don't trust the directions on the new pump to find the top for alignment. Unless the new pump lines up perfectly, rotate it until the bolt holes line up PERFECTLY. If the bolts are hard going back in, the pump is misaligned.

Q: I've always wondered how a water pump moves water through a pipe. A fan moves air by spinning a propeller-like set of blades, but does a water pump work the same way? Or is there some other kind of mechanism inside the pump that draws water from one place and pushes it to another?: IT CAN BE LIKE A FAN (CENTRIFUGE) OR IT CAN USE SUCTION AND GRAVITY LIKE A WELL PUMP

Q: What is a water pump for?: Providing kinetic energy to increase the flow of liquid to an energy increasing device for required head and flow

Q: To express in writing, you can add appropriate pictures (composition form, preferably 600 or more, not enough, OK, I put together a bit, will give points!) What kind of person would you help me with?: The main flow of water pump (take centrifugal pump as an example):Technical determination of Drawing > raw material storage > mold preparation > casting moulding > machining > parts experiment > Assembly > performance experiment > painting packing > storage.Here are a few key steps:1) the technique determines the graphMainly the work of designers. Generally according to the parameters of the pump (flow, lift, cavitation, efficiency, etc.) to determine the specific speed of pumps, impeller form, impeller size, impeller material, pump body, pump shaft and so on. One of the most important thing is to draw the impeller woodenpatterns.2) die preparationThe mold is mainly composed of workers according to the water pump impeller woodenpatterns production model.3) casting moldingThe casting molding sand is made on the base of the mould.4) machiningWater pump parts processing, because it has hydraulic flow channel, in considering the positioning clamping standard, must find the correct flow channel of the correct position. Avoid assembly, resulting in water pressure chamber and impeller flow channel skew, dislocation, uneven gap, or even rub, affecting product quality. In order to ensure the accuracy of parts manufacturing, it is necessary to design the appropriate tooling, and reasonable arrangements for technological processes, control process factors.

Q: can a worn water pump make the car idle high while in park when driven for a long period of time......03 grand prix: The water pump is only an impeller and moves fluid through the engine for the purpose of cooling. With that in mind, no, it should have no effect. Suspect you have a vacuum leak that is causing your high idle, check for a high pitched whistle and when you find it, fix it.

Q: How to design its control circuit, to prevent it idling, what peripheral equipment do you need?: The empty transfer of the centrifugal pump causes dry grinding, and the pump is overheated and seals out.Frequency control cabinet can be used to set their own frequency required job requirements, the external need is contact, is the pressure gauge

Q: How to introduce water pump?: The so-called Practice makes perfect., read the three hundred Tang poems will not recite poetry.Suggest a good understanding of the basic knowledge of water pumps, industry trends, understand the needs of the industry, as an expert in the industry!

Q: OK so i am new to RVing....I have an older 1971 trailer pull forester....It has a your normal fresh water inlet on the outside of the trailer, fresh water tank, and water pump. My question is actual a double part question #1 When i screw the hose on the inlet and start filling the water tank i hear it going in but i still have no water coming out the faucet...Does this have to do with the water pump? why am not getting water to anything except i hear the tank filling up?!?#2 Is the Water pump A/C or D/C......I have that little pull knob (that i guess turns it on or off) and i was curious if i needed to be hooked up to the Battery in front to make this work? or should it work with the regular AC that everything else is working on?Thanks for any help: I am not completely sure but i'll share my thoughts. I'm not certain but I think the water tank should have a seperate fill up. If your filling your fresh water tank and nothing is coming out of your faucet, my guess would be the water pump. Check and see if there is a reset button on your water pump switch. If not there should be a breaker for it located somewhere in the camper. But if you screw your water hose in to your camper and there is constant water pressure then there should be some water without having to use the water pump. If not then I'm stumped..
