Q:My water pump was replaced 3 months ago,but it stopped spraying water yesterday, How do I unclog the intake / Outflow?

what motor/year/horsepower? If something's blocking the intake you'll see it stuck to the lower unit. Stick a small piece of wire up into the nipple on the cowl. Check to be sure the hose from cylinder head to the nipple hasn't sprung a leak. Take that hose off and make sure nothing's crawled up in there. Remove the thermostat cover see if there's a blockage in there. While you've got it off, toss the thermostat into a pot of water on the stove with a kitchen thermometer, see whether it opens at the proper temp (which should be embossed on the stat somewhere). Drop the lower unit see what's up with your new water pump. Maybe the water tube somehow came off the pump discharge outlet. If you're in the habit of starting your motor without supplying water to the lower unit then you've already ruined your new impeller. If there were any pieces missing from the old impeller when you removed it, then you've got neoprene rubber somewhere in the water tube or powerhead blocking the flow of water; all you can do is start disassembling till you find it.

Q:One month ago, mechanics replaced water pump for my car, 04 dodge stratus, 100000 miles. When I went to get the car, there was big noise coming out from engine. The mechanics told me it was because of sediment in auto oil system and he show me some sediment he took out. I know little about car so I thought he was right. But now the noise changed and engine light came on. I went to firestone to check it. The report said timing jump and cranked. The second day the engine died totally. And I went to another two mechanics. They said the previous one who replaced the water pump did something wrong to timing chain. But that mechanics didn't admit it. What can I do?

You're on thin ice with this, unless you had the timing belt replaced before 90,000 miles. That big noise was the pistons hitting the valves after the timing belt slipped, or more likely, broke from being worn out. When the engine's water pump is driven by the timing belt, the belt must be slacked to get the pump off, then tightened back up after the new pump installation. That old belt couldn't hold up under the tension. It's just bad luck for the mechanic he didn't think to question the age of the timing belt and insist that it be replaced. Of course that would cost a bit more. It will be an uphill battle. You might as well find a used engine if you want this car back on the road. Good luck to you.

Q:A pump, the flow rate of 30T/H per hour, lift 30 meters, should be allocated more power motor?

The actual use of power should be at least 5.5kW, I did not find 30t/H lift 30 meters of the water pump, and only he approached the model, supporting a larger power, and will not increase the power consumption

Q:the outboard runs fine and pumps water out with muffs on but when i put it in the water it doesn't pump any water at all. could it be that the impeller needs replacing? what do you think?thanks

No question about it. Replace the impeller. It's easy - the hard part is getting the fasteners off without breaking a stud. Be patient and use liquid wrench and give it an hour or more to work. Tap the nuts and then try them. A final resort would be careful (very careful) use of a propane torch to free the nuts. If not replaced, eventually blades will break off the impeller and foul the cooling system.... which can be a very expensive and difficult repair.....overheating is also very bad for the engine.... so fix the water pump.

Q:I just replaced my starter on my mustang and i when i took it out for a test drive i noticed the engine temperature rising. i drove for maybe 2 minutes max and when i parked the car it had a small amount of white smoke coming out of the engine so i let it cool down, and when it cooled down i checked the radiator, it had absolutely no anti-freeze, which is weird because i had just put a gallon of 50-50 anti-freeze maybe a week ago. So to test it i put 3 cups of water in the radiator turned her on and water was spilling from the water pump. So me and my dad have concluded we have to replace the water pump. I called up Autozone and they have a water pump replacement kit for $70. We don't have money too pay for the labor so can some1 please give me a step by step guide to replacing the water pump.

So did you get it changed? mine just broke. do you got any pointers?

Q:The role of impeller in water pump

The impeller rotates at high speed so that the centrifugal force is generated by the water, and the vacuum is generated in the middle of the impeller, and the water source is continuously sucked into the impeller to increase the kinetic energy of water and play a role in promoting water.

Q:Can I use Ultra Blue gasket maker on a water pump? The packaging is not labeled high heat.

its alright to use it with a gasket in a very small amount, but i wouldn't want to use it to make a gasket with,i use it when replacing gaskets and things ,but in very small amounts,the high temperature gasket maker is one of the better ones to use for doing this on a water pump,used in small amounts though you can use the blue just to act as a holder to help keep the gasket in place,but i don't recommend it to make gasket with ,good luck.

Q:there is a knocking noise coming from the water pump pulley..i think, the pulley also wiggles when its running. If that's what is wrong, how long do i have to fix it and is it hard and expensive to fix?

No it isn't hard to fix, first loosen the little bolts on the water pump pulley, then take the belt off, then unbolt the water pump and take pulley off old pump, clean off old seal from block, put on new seal, you may have to use gasket maker or silicone, install new pump, and bolt pulley on to new pump, then reinstall belt. Oh I forgot you will have to drain the antifreeze before you start, and refill it after you are done! Start the car and let it warm up and look for leaks, if you see a leak you didn't get it sealed properly and will have to repeat the sealing process and antifreeze. Takes an hour or so to do!

Q:22KW pump motor direct start circuit breaker and contactor size? Concrete calculation method

22KW the water pump motor is 380V. 22KW rated current is about 44A, 10 square copper wire is enough, the motor will often start off ah, if it is not available for DZ108-63 50A, CJX2-50 50A contactor is 380V.Pump motor (pump motor) according to the structure classification, should be divided into horizontal motor and vertical motor. Because of the work characteristics of pump starting torque is relatively small, the starting frequency is relatively small, relatively long time continuous operation and other characteristics, so the majority of pump motor asynchronous motor cage rotor or synchronous motor.The pump motor should be selected according to the selection of shaft power; motor shaft power power is greater than one level; for example: axle power is 15KW, select the motor should be: 18.5KW for motor with very few, according to the actual working conditions. 2 pole motor is generally used in the head of micro height, flow is not large (calculation is more complicated). Large flow, small lift occasions can choose 4 pole motor. Super large flow, lower head select 4 or 6 pole motor, when choose six pole motor, power can be reduced according to the shaft power of a grade.

Q:water pump contents

That is your first problem. Once that works, turn it with a 1/2 in wrench and clamp the hose.
