FAQ

In 2005, the water pump, export pressure in recent years decreased year by year, the running current is increasing, there are 4 pumps are like this. Professional personnel advice please!

The reasons are as follows:(1) motor guide bearing wear, water pump rubber bearing wear, sealing ring wearMotor or water pump bearings wear, will make the submersible pump in the machine on the wrong state of work, serious damage to submersible pumps, stator windings burned. The method is to repair or replace damaged bearings and bushings.(2) thrust bearing wear, submerged pump impeller and lower cover wearThis situation will also make the submersible pump on the machine in an abnormal state of work, serious damage to the submersible pump. The treatment method is to check the cause of the wear of the thrust bearing. Whether the mechanical seal of the shaft extension is damaged or not, which causes sand particles and impurities to enter the inner cavity of the motor, causes excessive wear of the thrust bearing. If it is caused by the mechanical seal of the submersible pump, the replacement of the thrust bearing, thrust plate and impeller, lower cover plate and other parts shall be replaced by mechanical seals at the shaft extension end.(3) the flow of the submersible pump is too large or too smallThe use of submersible pumps flow beyond the scope of use will make the motor overload of centrifugal pump or mixed flow pump, excessive flow, the pump shaft power increases, the motor overload; for the axial flow pump, the flow is too small, the pump shaft power increases, the motor overload. The treatment method is to adjust the valve properly, reduce the flow rate of the centrifugal pump or the mixed flow pump (increase the axial flow pump), and make the flow of the pump in the normal range of use.(4) the shaft of the submersible pump is bent and the bearings are not concentricThis is a serious case of submersible pumps, should be immediately overhauled, straighten the bent shaft, replace the unqualified bearings, re assembled submersible pumps.

I have a slight idea but I would like to see what steps other people have taken. I have a 1992 ford escort that needs a new water pump, what steps have you taken to replace it?

if you're going to do it yourself first I recommend getting the book for the car sometimes the library will have them..you also want to be careful when changing the water pump because your timing belt is hooked up to the water pump. If you misalign the camshaft or the crankshaft pulleys or turn them independently when the belt is off you can cause damage to the head of the engine (very important: your timing will be off..you don't want that). To start with though, you will have to take off your accessory belt and the accessory crank pulley, then take off the timing belt cover and use the crank shaft pulley to line up the marks that are on the pulley and the engine (on both the crankshaft pulley and the cam shaft pulley) carefully take the timing belt off (replace the timing belt and the timing belt tensioner..trust me it'll be worth it). You're going to have to drain the antifreeze before you take the water pump off. (I would also replace the thermostat because its cheap and you already have the fluid out) The install is pretty much the opposite. (again make sure the marks line up on the cam and crank pulleys and don't turn them independently when you're putting the belt back on) (short answer: get the book and/or have someone that's done it before help) when your done you can say you did it :)

here is the problem with my water pump control switch settings. the water is being used, runs dry and stays off for sometimes 3 minutes or so.i realize the springs control the cut in and cut out. do i need to make the spring more compressed to make the pump come on sooner? or do i need to make the spring looser to make the switch come on sooner?when i read/hear about adjusting the cut in. the answers seem vague because i do not know the perspecitve of the spring.does compressing the spring make the swith flip easier? or does compressing the spring make the switch harder to flip on?i installed a new 30/50 switch today. My air tank was at 50 or so PSI. but i dropped it to about 30. is the goeal to make the entire full system 50 pounds? because after my pump cycles i get about 70 psi!!!

The problem lies with the new 30/50 switch. With Your pressure tank empty of water, set the air pressure at 28psi. What is happening is when the water pressure drops below about 45 psi - the air pressure (50psi) on the bladder is forcing the water out rapidly. Then the pump has to work like cracy to overcome that bladder pressure! Easy Fix. Make sure the tank has no water in it.

what is the actual capacity of 15 stage 1 H.P. Borewell submersible pump. I mean can it draw water if it at 300 ft depth. Is 15 stage 1 H.P pump capable to draw water

Yes you can in fact it is better to use a larger hp pump. A 3/4 hp pump can recover the water with less of a degree of workload there by conserving the energy it takes for a smaller pump to do the same required work

If there were no water at the discharge of a pump and then you had just fed water through and measured the pressure of the gauge...would that be a different pressure if the whole system (both inlet and outlet) were continuously filled with water?

1.If there is no water at the discharge of the pump then there can be no pressure. 2. If there is water at the discharge of the pump, but the pump is not running, then there will be a pressure in the system. 3. If the pump is running, the pressure in the system will be higher than at 2.) above becuse it takes additional pressure to move the water through the piping. The flowing water requires additional pressure to get thru the piping system.

Why does the water pump leak?

The sealing ring is invalid

Car is ford taurus 98.The car had some problems including overheating as thermostat was bad so was was not working. i drove it 25 miles to garage (i had to stop once because too hot to let it cool), i brought it to Ford who replaced the thermostat. Now they tell me some bits of thermostat broke and they need to replace the waterpump and want $620 for it. The other repair were also extremely expensive and i want to bring it to another garage 1.3 miles away on flat road.-1- is it safe to drive 1.3 mile with no water pump or should iget it towed?-2- should i have to pay for the water pump or is it ford's fault if they did not remove the bits of broken thermostat before reconnecting new thermostat to hose ? Can i prove that the pump was working when i came in if i drove 25 miles with it ?Thanks for your help.

alright- you have a lot of things going on here. you have an older model vehicle with what sounds like a couple of issues. your best bet is to have the vehicle towed. letting your vehicle overheat is it not a good thing - can ruin your engine. Best not to risk it even tho 1.3 miles is nothing really. if you feel the shop is at fault. And it's a ford retailer - contact the fort corporate offices and file a complaint and ask for good will for the repair and see what happens. Couldn't hurt to ask. Take care and good luck.

Fire pump room is required to set up water pump control room?

What is the concept of fire pump control room? If there is a control room host automatic alarm automatic fire alarm system of words (through the pump distribution box can also control) can control the fire pump, if there is no distribution box automatic alarm system you can through the pump room control
