Q: I am going to replace the timing belt , tesioner and idler bearing on my 2000 daewoo leganza. I noticed some of the kits have water pumps too. It is likely to break like the timing belt?
I would suggest to replace the car itself.
Q: I have an 8 gpm pump at a depth of 170 ft, I am pumping the water 2000 ft in a 1 1/4 inch line. I need to know how many gallons per minute I am getting.
Use the Bernoulli equation, aka mechanical energy balance.
Q: i have a 97 mercury mountaineer and i recently got the thermostat changed in it. after doing so we noticed that the car was leaking antifreeze. we checked to make sure everything was tight and there was no cracks and my uncle said he thinks its the water pump how can i tell
Water pumps usually leak when they wear out. There is a weep hole on the bottom of it - you will see antifreeze coming out there. Another clue is overheating if the pump is not moving water.
Q: 300M head of 11 stage centrifugal pump with 22KW motor, empty (not water) current of 13A, the water into the pump, current up to 44A, open the outlet valve of the current rising to 100A, immediately shut the gate current is up to 170A, the motor stop. Without any problems, not on the impeller pump shaft is not clean the shell the balance sheet, no wear, bearing normal.
(1) the influence of the basic installation on the equipment.The quality of equipment foundation installation has great influence on the quality of equipment operation. Iron pad placed properly, causing around the foot bolt hanging device, in alignment and fastening process for iron pad hanging, tighten anchor bolts will cause deformation of crosshead slide in the crankcase, the cross head is blocked in the operation of reciprocating load increases when the chute.W5 type reciprocating vacuum pump in the structural design of the cylinder body is cylinder, and the piston, intake and exhaust valve after the heavy weight in the foundation design without considering the cylinder support or hanger, the cylinder will be in a suspended state, because the weight of the crankcase cylinder will cause deformation of the cylinder and slide and slide the concentric degree of difference, so that the cross head is blocked in the slideway and the piston reciprocating operation is blocked during the reciprocating motion in the cylinder caused by the increase of the load.According to the above analysis, inspection found that the vacuum pump end of the cylinder body is slightly lower than the end of the crankcase, cylinder pad iron is low, deformation of crosshead guide foot bolts, the cross head caused by load increases in the slideway and the piston in the cylinder reciprocating operation is blocked, this is one of the reasons causing motor overheating.(2) cylinder and valve coking;The influence of process, cylinder and valve of reciprocating pump is easy to coke, Coke will cause the piston cylinder and piston in reciprocating cylinder operation when the load increases the valve is blocked; coking will cause poor exhaust, the valve closed lax, increasing load, low vacuum degree; clearance at the cylinder piston striking the cylinder will cause coke it will increase the load of cylinder, valve has found the phenomenon of coking, which is mainly caused by the low degree of vacuum.
Q: What will the water pump reversal situation?
The same will reverse pump water, but the head and the pressure greatly reduced, I just finished debugging a pumping station, Stephen multi-stage pump, installation of equipment: multistage water pump motor power 4 75KW 76% head 100 meters, frequency control, motor nameplate nominal current of 143. According to the direction of the motor steering pump mark OK set the start time of 28 seconds after 5HZ boot head start frequency can reach 50 meters (at that time did not install the pressure gauge cannot observe the water pressure of current) in early 118 about 3-5 minutes after the current is reduced to about 97, there are inspection found no problems, suspected pump problems, suspected foot valve not completely open, the reason cannot exclude the end of valve, almost in despair when the thought is not marked in the direction of the pump, re set to restart the current 129.5A to observe that later installed capacity reached 0.55MPa duct pressure gauge head close to the design requirements, the problem on the manufacturer's mark is reverse.
Q: My water pump broke on my volkswagen golf tdi so I took it to a garage. He charged me ?250 for a new pump and fitting. When I came to collect it he showed me the broken water pump, when I asked if I could keep the broken pump that was taken out of my car he said that there would be quite a quot;heftysurcharge for me to take it with me because they have to send them back to Volkswagen. I thought it was a bit strange. Is that normal?
He would have charged you a core charge (sometimes more than the replacement part costs). A lot of companies refurbish old parts and require you to turn in the bad part so they can repair it.
Q: The pond is 10' long x 2' wide x 1' deep. The pump is at one end and water is raised 1' to a buried garden hose that is maybe 12' long and then at the end it goes up 2' to release the water over some rocks. I had a 330 gph pump that worked well but died. That size has been discontinued. Go smaller or bigger? DON
Hi Don, In my point of view it depend on the final effect that you want to create. If you are in the mood of water theraphy, mean that you like to the sound of the water fall, you may want to consider a pump size that a bit higher than your previous ones, and vice versa. In a nutshell you should be able to determine the effect of the waterfall you need since you already have your previous old pump running before.This should be your best guideline to check the size of your new pump needs. There is a bit of extra caution needed if you are thinking of using a bigger size of pump, you should ensure that the pump are not sucking to fast of the water. If this is the case you might be end up having your pond drain half tank. You can get the circle time for the water flow base on the pump size from the catalog.I'm sure your hardware guy are gladly assist you in understanding the matrix conversion Pond size over the pump size,since I can't explain in detail here about the graph reading. But in most cases I just relatively using the first option of comparing the old pump size with the new one. Hope that help. Fazla
Q: What motor does the pump use?
Single-phase general use YL series, three-phase general use Y, Y2 series.
Q: 94 f150,302. my pump is still leaking after doin the job twice. its a new pump, the first time i used the red silicone between pump and plate,both sides of gasket,and the housing on the block. leaked. then did it again with high tack gasket cement and still leaks. i cleaned all metal both times with brake clean before installing. same with thermostat housing,small leak. ive done 100s of pumps over the years,no problems, so please no rude remarks on mechanical ability. what could it be? it leaks up front of the motor above the crossmember where ya cant actually see the leak,its not a freeze plug. bolts are torqued. any ideas ? thanks
never rule out a freeze plug. it could also be a cracked block. it could be in your interest to pressurize the system and trace the leak back to the source. the pump could be fine.
Q: I have a small leak in my water pump and my check engine light is on throwing a P0303 code and it appears the two might be related.
As far as I know Bars stop leak will not work on a moving part like the seal on a water pump. This is an opportunity to have fresh anti freeze in your car. Get the water pump replaced and have the system drained and filled with fresh. Use a pre-mix or dilute regular antifreeze with distilled water. Many places have hard water which clogs radiators and heater cores. Take care that the system is bled of any air when refilled.. Anti freeze contains water pump lubricant for the seal. If it had been changed last year you may not have this expense now.
