Q: how do get the tub off the washine machine to fix the water pump?
Can you tell us what brand? They do NOT make them all the same either in placement, access, or attachment.... So to be able to help you properly, we need MORE INFO, PLEASE!!!!
Q: My friends car is a 1997 jeep wrangler. The belt broke and she took it in to get it replaced and they told her metal from the pully that broke got into the water pumpand they have to replace that to? WTF? it makes a squealing noise and they want to charge her another 300 for that! we just don't understand how that could be if the pump isn't even leaking?
Well like someone else has mentioned the squealing usually comes from the round pulley that the belt rides on maybe in your case some metal has damaged the idler puller on your water pump and that would definitely give you a consent squeal. the price to replace your water pump is very excessive the part at any over the counter parts store ranges from 30-45 dollars the labor too do this on a jeep is 2.2 hrs @ the shops hourly rate which also varies but 45-55 hour isn't unreasonable... so on the high side of these figures it should be about 120.00labor 45.00 parts so a bill of $165.00 would be more appropriate......but if you don't make the repairs knowing it still has a problem you might void any type of repair warranty on your current repairs already completed...hopefully this has helped you somewhat...jimboz
Q: A guy i know changed the Water pump on my 02 Chrysler Sebring with a 2.7 in it because it was leaking coolant, when i got it back the leak was fixed but now there is a ticking noise. He thinks that the Timing Chain Tensioner needs to be replaced... can i get some opinions here? does he sound correct?
It is possible. The water pump is driven off the timing chain on that engine. Why didn't he replace the tensioner when it was apart is a good question. The fact that it is now ticking isn't a good sign. I hope it was lined up properly.. get it looked at soon before there is the potential for damage.
Q: How many kinds of pumps are there? What are the advantages of soft start?
Start the pump direct start, soft start and step-down start, starting four, direct start motor is generally suitable for small power, we usually use, at 15kw below the pump price; Step-down start is the star delta conversion is started, start is two times speed to reach the rated speed of the general. Using the above 18.5kw, the pump price moderate; soft start is gradually increased to the rated speed of the pump, the impact is very small, the price is relatively high, generally 3 times the step-down start; is the most advanced frequency conversion start, not only have advantages of soft start, also can be set to work at any speed, there are significant effect on energy saving.
Q: I'm trying to sell my 97 Ford Escort. It needs a water pump but I have no idea what the cost is. I just want to know so I can post an estimate of how much it costs on the site I'm selling it on.
We all know what you want to use that water pump for.
Q: What does the pump lift mean?
The pump head is the height or length of the distance from the pump to the outlet
Q: Ok i was wondering which is the from hose off of the motor the bottom or top since i thinl my heater core hose are reversed and i only get nuke warm air and not hot and yes ive got a brand new heater core, new anti freese, new thermostat and gaskets and all hoses are clear and not rust in the system
My husband and that i agree 3 hundred%. He has a seventy six with 296,000 mi.-on no account any artwork achieved different than recurring maintenence. I had a sixty 3 that I drove for 19 years and offered back to unique proprietor in 1992-it nevertheless runs large. It had a 327(finely tuned) and have been given 31 mpg hwy. there replaced into room to artwork below the hood, certainly become conscious of factors and do maintenance, or jury rig till an entire restoration replaced into made. Have an 80 5 now and not something yet issues!!! Sorry I enable the sixty 3 pass-he won't area with it. the only progression in extra present day is stereo, no longer the automobiles themselves. a visit to wrecking backyard will demonstrate extra extra present day ones than older. information do no longer lie. save your truck!!!
Q: About how to calculate the pump installation height?
See the design manual, town water, volume P312This formula is: NPSHA = HgHzhsZs > NPSHRAccording to the actual installation of NPSHA pump cavitation can provideThe pump NPSH provides NPSHR pump samplesAtmospheric pressure Hg pump installation siteHz liquid under certain temperature saturated steam pressure.The head loss of water pipe HsThe installation height of ZsIt is worth pointing out that, with regard to Hz, with temperature related, and some problems are not given temperature, and that value is also very small, in the calculation should be able to ignore (0 degrees C, 0.06mH2O).And atmospheric pressure, we usually use 10mH2O, in fact, and altitude also related. When the altitude is 0, it is 10.3
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: School project. My group cannot find this answer.
Water pumps are rated by output (cfm,gpm), max. suction lift (ft), total head (ft), amount of power used (Hp), and whether they self-prime.
