Q:How to design its control circuit, to prevent it idling, what peripheral equipment do you need?

It burns and seals when idling. The individual thinks that it can be indirectly reacted according to the pressure change in the pipeline, and the electric contact pressure gauge can be installed on the suction pipe

Q:for a school project, i need to boil cold water using a vacuum pump. I did some research, but i still didn't find what i needed. I need to know what kind of pump i need for this, and where i can get one for cheap, since i will only use it for this project. if you know how to actually use it, you can throw that in as well. thanks!

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:The truck is a 1982 Ford pickup F100. We didn't realize it was an F100 at the time and we put the F150 water pump on it. The water pump fits perfectly, but is this going to mess up the engine at all?

No it won't mess up the engine as long as there are aren't any leaks meaning a new gasket is used, the belt is adjusted correctly and is aligned, and the thermostat is replaced using the correct temperature item. Any good parts store employee can sell you the correct thermostat.

Q:The water burst how to repair?

The general water burst positions for the pump body, pump cover, if not very serious welding can be used to trap, at which point the attention electrode material, most of the water pump are cast iron, so the welding difficulty is not small.If it has become deformed or has split into parts, replace it.

Q:can i drive my car ,with a blown water pump, 5 miles to a service center?

its possible. i dont reccomend it, but if you do, get a couple or few gallons of just water, depending on how big your radiator is, and keep an eye on your temp gauge, if it starts going up, shut off your car, wait 5 to 10 minutes, carefully open the cap on your radiator, and put water in it untill it fills back up. i had a busted water pump i drove 20 miles on everyday for about 3 days untill i had time to fix it, it wasnt a bad leak though, and that still sucked, i would honestly just pay the small amount for a tow truck for the 5 miles.

Q:I've noticed after driving my car for a while recently it squeals while accelerating. I'm wondering if its the water pump cause I've had a coolant leak for a while. I poured alluminum sealer in the reservoir and its stopped the leak almost completely though. If it was a broken pump, would this sealer have stopped the leak like it has? I drive a 2000 saturn sl2

If you have ample room to change a water pump, go for it; however, keep in mind some cars use that belt for timing. If the belt is also a timing belt, take it your branded dealer.

Q:I'm using an old Mitsubishi Lancer. Recently I changed my water pump it was leaking.To me it looked like a piece of metal, with a small fan thing (not motorized) How can it fail? There is no mechanics to it, just like a pipe with a fan (or turbine)I also messed with my radiator, I unhooked the main hose to clean out the coolant, since the plug was jammed. Could this have contributed to the failing of my water pump?

The water pump has a gasket inside to stop coolant from leaking out. When the gasket fails, coolant comes out of what is called a weep hole. If you don't replace the water pump, the bearing gets saturated with coolant and fails. When the bearing fails, the water pump pulley ceases and the belt fails. I have seen this too many times.

Q:I am trying to evaluate my well water pump and water system to see if the pump is cycling on/off too frequently. What is the optimal quot;ontime? What is the optimal quot;offtime? I have heard the term quot;short cyclingquot;, but no times were attached. I have heard that too frequent cycling can cause a problem, but, again, no times were attached. How can one tell when the system is working within the optimal/normal range, so that no harm is being caused to the system? Thanks.

There is no optimum time. This is dependent on several factors. Assuming you are pumping into a small tank which is pressurized by the inflow of water from the pump (and the pressure also controls the pump) these reasons can be excessive use of water, the air space at the top of your tank has been absorbed into the water over a period of time and the volume of compressed air too small causing the pressure to drop too fast, or you could have leak in your water piping. If there is not enough air space in your tank, the pump will cycle extremely fast. If you don't have a tank, then the above information is incorrect. Good luck.

Q:Is a 3000 watt generator sufficient to power a 3/4 horsepower water pump?My house has a 3/4 horsepower pump that it uses to pump water from the well to the house. I want to purchase a generator that will be sufficient to power this pump in a power outage. Is 3000 Watts sufficient?

Danny and GTB give a good answer, I just add some: As a rule of thumb, 1 horsepower (HP or hp) is equal to 750 watts, and a motorized electric equipment at start up will suck electricity power about twice as much as its specification. Is you pump equipped with a three phase or a single phase electric motor? You have to suit it with the generator. As for the generator, if possible you choose a generator with big flywheel, with slower RPM -rotations per minutes- than a generator with high RPM, because a water pump will frequently on and off according to the usage. This could cause the generator to wave down and up accordingly. Or a generator equipped with an electronic governor that will react fast enough to the frequent on and off load of the water pump. Hope the best and God bless you and good luck day by day!!

Q:What is the difference between self-priming and non self suction?

The self-priming condition of the centrifugal pump is that a small water tank is attached to the pump body. Don't use water every time you start. No suction, no water tank. And the use of volumetric Self-priming pumps, such as car cleaning, high-pressure pumps are in this category.
