Q:how to make a mini water pump?
I doubt that your motor is waterproof. You would do better to just purchase one of the many fountain pumps all ready available at many home improvement centers or online. They are water proof and have the pump and motor all in one enclosure.
Q:What's so good about having a water pump on my stand alone ice maker?
The ones that make cubes, not slices make a sheet of ice by continuously pumping the water over a flat evaporator. Then once the ice builds up it reverses the hot gas and the slab melts off falling on the cutting grid which cuts it in to cubes. Those that operate this way are much faster and produce more ice. No pump, no ice.
Q:Water Pump 1989 F250 5.8L 351w?
that don,t sound like the water pump. if it was the pump then it would overheat and leak out. check to see where it,s leaking at. if it,s leaking from the pump then it will have to be changed even though it still might not help it to idle. it,s not really that hard to change the pump on a 351W . the hardest part is getting into it. you might have to remover some stuff so you can work. the belt and water pump pulley will have to come off and the fan but that should let you into the bolts.
Q:How long should a new water pump last on a 1995 honda accord wagon LX?
Short answer: At least 75,000 miles, even under extreme conditions. The main cause of water pump failure is bearing failure due to crud (mostly rust) mixed in with the water/coolant mixture pushed through your engine by the pump. Variables: If you did not have complete cooling system flush at the last pump's replacement, the new pump's life expectancy would be reduced, but not significantly. Many folks misdiagnose engine overheating and the appearance of coolant on their garage floor as pump failure. If we believe Click and Clack the Tappit Brothers (a.k.a. Tom and Ray Magliozzi) you did not actually get a new water pump a year and a day ago, but you did buy a tank of gas for the mechanic's ski boat. Take your car to a reputable mechanic's shop (referred by a happy customer or 6, or Angie's List), dress as a peasant and tell 'em the car was inherited by you after your parents died in a horrible fire. Bringing 4 screaming infants couldn't hurt, either. If you can't rent some kids, you may consider what many women do, but it involves removing any rings, wearing a low cut top, smiling a lot and repeatedly flicking your eye lids as you play with your hair...
Q:water pump went bad. changed it. car is still overheating. why?
When was the last time the system been drained flushed and *cleaned? A 14 year old radiator and heater core will be loaded with corrosion and rust. Prestone Super Radiator Cleaner can be used on mildly dirty cooling systems. *Follow the instructions on the back side of the Prestone Super Radiator Cleaner. The instructions are totally different than the quick, worthless rinse cleaners. GM makes a one part powered acid cleaner that works better on really dirty cooling systems. When in doubt change the AC-Delco thermostat with another one from a Chevrolet dealer. Flushing is easy when you splice-in a Prestone or Peak flushing T in the heater hose *return hose from the heater-core. Any trusted private mechanic or Chevrolet dealer can do a *cooling system pressure test to see if you have any external or internal coolant leaks. Never exceed a 50/50 mixture of DexCool antifreeze and distilled water. If someone has been mixing brand X antifreeze with the factory installed DexCool in your cooling system the coolant will turn to mud and plug-up the cooling tubes in the radiator core and mat the cooling passages in the engine. The secret of perfect heat-transfer in a cooling system is clean cooling passages, a new AC-Delco thermostat and radiator pressure cap. Remove and clean the plastic coolant recovery bottle with Wisk, hot water and a round household scrub brush. If you exceed a 50/50 water and DexCool mixture, it will not adsorb heat from the engine as efficiently or get rid of the heat in the radiator as well as a perfect 50/50 mixture. Always buy 100% DexCool Antifreeze and fill 1/2 the total capacity of an empty clean cooling system first with 100% DexCool then fill the remaining space with distilled water.
Q:how is water pumped from deep wells?
You push it from the bottom. Home water wells have a plastic hose and a power cord along side and the pump is attached to the end and lowered down the hole and pushes the water up the hose. Oil wells are commonly pressurized, but where not that donkey engine you see in oil fields is attached to a long rod or cable and at the bottom of the hole is a pair of valves and a piston and the mechanism pulls the oil in the lower valve and pushes it through the upper valve and that pushes the previous oil up the pipe.
Q:About water pump selection
ZGD1.5KW screw pump, lift 120 meters. Caliber inch. High pressure. Screw type. It can absorb more than 30 meters of water.
Q:How to fix water pump?
The leaking water is telling you that the pump impellor is worn and you need a new pump. Sealed Unit, cant be repaired.
Q:Why is the water pump smaller than the pipe diameter?
The size is only a matter of convenience or experience, and a small number of tubes are already available. As long as you can pick it up, you can use it.The so-called thick pipe to reduce resistance is a certain relationship. But it shouldn't be your decision to choose the big one. Then why don't you choose the big three? Four or the thicker ones?! @! The resistance will be smaller!!!!- - - - - - - - - - - - - - layman; look at the knowledge of fluid mechanics!!!The question is a conclusion, explain why not one or two words, learn the knowledge of fluid mechanics to know why -- try to answer it, that is to improve the water pump outlet total pressure head, intuitive feeling is to have enough pressure to pump out the water pressure. As for the big three or four, it is necessary to ensure that the flow velocity in the pipe is more uniform, otherwise the flow near the pipe wall will flow or flow too slowly due to viscous action.
Q:water pump in a 96 neon?
Water pumps cost from should cost from $40 to $100. The car probably has even more problems than the water pump considering the cars age and the price for it. You should take it to a local mechanic so that they can check it out and give you their input before buying it.
