Q:Water pumping work problem?
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:well water pumps and systems?
ANY extra info is a plus. Well size and construction, depth, water level, production test results, and pumping apparatus, all help in troubleshooting problems. The two most likely things I can think of that would make your water pressure act the way it does are as follows. My first guess is that your pump is capable of pumping more water than the well will produce, thus drawing the level of water in the well down to a point where the pump catches some air and quits pumping. The pump continues to turn and when enough water comes into the well to cover the pump, it's starts to pump water again. Second guess is that you have a thermal overload tripping and when enough time goes by, it resets and turns the pump on again. Overloads often trip when you have a low voltage situation at the motor. You can get low voltage form bad connections @ splices or the contacts of the pressure switch. Most well water systems go a long time between maintenence calls, especially at first when EVERYTHING is new. My advise would be to call the contractor that drilled the well and installed the pumping equipment. Hopefully they are one and the same. The contractor knows the original conditions and all equipment used, even the stuff you can't see. Because the system is relatively new, the original contractor MAY be inclined to cut you a deal on repairs. We don't know how long this problem has existed, but perhaps the system really wasn't up to par right from the start. Good luck. When you talk to the contractor, try not to sound to accusatory. He may have done his best with the geologic and economic set of conditions he was given. Nobody can make gold out of lead.
Q:What does diving pump 80JYWQ40-15-1600-4 stand for?
Because each manufacturer's label is different, the country although some specifications, but not enforced, so purely from the literal meaning is difficult to explainWe will try to solve the following problems:WQ-- sewage submersible pump80-- outlet diameter of water pump40 - M /h fand flow15 lift M1600 speed, r/min4Kw powerAs for J, Y is rated as sealed form and waterproof gradeI don't know whether it is correct or not
Q:Does the water pump and the circulating pump belong to the centrifugal pump?
They're all centrifugal pumps!
Q:Water Pump Doesn't Hold Presssure?
If there is space try to hit the head of the bolt with a hammer, the shock from the hammer blow will help you to loosen the bolt. Failing that the next thing to try is an allen key socket, with this you can use a long strong arm to apply extra torque to the bolt. Be carefully not to open up the head of the bolt as this can be a major pain. If you still cannot get it out then if the water pump is to be replaced try to get an angle grinder on the bolt to cut its head off. Once the head is off and the pump is out you can use a stud extractor of a good vice grip to remove the stub of bolt left over.
Q:how to fix my water pump to my e34 525i its overheating no leaks?
well before you go through a task like that have u checked for opther options? check it out- First: make sure that your radiator is in good condition, check the belts, the hoses and the coolant level. Make sure that there is no coolant leaks. Check the condition of the shroud for cracks its proper installation. Car fluid or coolant circuit element just changed: Your overheating is probably due to air trapped into the coolant circuit. Use the bleed screw to bleed the circuit. Then bleed again, again, again and again. Nothing had been changed, car is overheating while idling or heavy traffic: 1. Check that the thermostat works and opens. 2. Check the fan clutch. Car overheating while driving. Not stop and go. 1. Bleed the cooling circuit. 2. Check the thermostat. 3. Check the water pump. 4. On the 535i, check the bypass hose located and attached just above the upper hose neck on radiator and runs along the inner walls to the Resivior tank. If it is plugged, the car will overheat. Overheating with A/C on, or very high temperature only. 1. Check that the auxiliary fan is working properly(Bentley manual page 170-4). 2. Check the fan clutch.
Q:96 vw golf gti water pump?
the water pump is external to the engine, no need to touch timing belt unless your changing it, tools needed- 13mm wrench-22mm wrench - 1/4 drive ratchet-10mm 1/4 drive socket- 3/8 drive ratchet- 12mm 3/8 drive Socket-13mm 3/8 drive socket-19mm 3/8 drive socket-16mm 3/8 drive socket 3/8 drive Extension-pliers- flat blade screw driver- 6mm 3/8 drive allen socket--- remove drive belt's- remove p/s pump, a/c compressor( do not disconnect either they will move out of the way)- remove alternator(disconnect battery first)- remove the bracket assembly( four 13mm nuts three hidden in the holes) there is the water pump(two 19mm tall bolts with studs hold it down, 10mm T bolt passes through the timing cover)
Q:Submersible water pump in aquarium?
well it depends, do you have any small fish? and how is the water cycled in the pump? it needs to be protected so that fish dnt obviously get sucked. before you add it in tho need it submerged in a bucket of water and add several teaspoons of salt; that will kill all the bacteria that may have grown on and inside the pump. leave it in there for minimum 24 hours (just to be sure).
Q:How long should a new water pump last on a 1995 honda accord wagon LX?
Unfortunately most water pumps,even new ones, are warrantied for one year so while you may have to pay for another one I'd be sure whoever I paid for the labor was a different mechanic. Even new pumps can go bad prematurely but a reputable shop would probably make some allowances since its so close to the warranty limits. The other advice given about the coolant is spot on too. It should have been refreshed at the time the pump went in but just because it should have, doesn't mean it was.
Q:Pump impeller diameter plus assembly what changes? What's the effect on the motor?
Two item 1.5 kilowatt type self suction pump original impeller 14.7cm installed 15.5cm may be a problem.After the impeller increases, the flow, head, shaft power will increase (increase in volume see the following formula), the original 1.5KW motor may overload operation.The larger the diameter of the impeller, the greater the lift, the greater the flow rate, because the flow rate of water depends on the centrifugal force generated by the impeller rotation and the line speed on the tangent. The greater the diameter, the greater the centrifugal force and the linear speed. The relationship between the centrifugal pump water delivery and the vacuum degree is that the centrifugal pump is the centrifugal force principle to complete pumping. Without water, the time and space turn will burn out the equipment. Vacuum pumping or vacuum pumping two times.The vacuum of the inlet of the centrifugal pump is composed of three parts (the equation of the inlet of the pump and the level of the suction liquid).
