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:What are the brands of air conditioning pumps?
Look, there you are. The East is connected. The stainless steel in the south is pretty good. Both of them are famous in China
Q:Problem with my water pump!!?
Sounds like it's waterlogged. That's what it's called when the water and the air in the resevoir tank mix, and the volume of air gets so small as to not be able to provide any decent compression with which to push water through the system. At that point, any time you open a fixture, the pressure drops enough to turn on the pump, and when you turn off the pump, if it's just right, it will turn off and then back on, then off, then on, back and forth till you shut it off and it can set and stabilize, till you need water again. The solution is to reintroduce a sizeable amount of air back into the top of the tank. If it's an older tank, without a bladder, (identified by the small bulge around the center of the tank and either a blue or rust color), then the best way is to simply drain the tank and restart the system. That way it will trap all the air in the top of the tank and you'll have enough pressurized air to push a gallon or two of water out, before the pump needs to kick on again. If it's the bladder type, with the bulge, then the bladder has blown and you're, in effect, working with a standard resevoir tank now, except that it will have an air valve in the top like a bicycle tire, so you can pressurize it with an air tank. If so, open some fixtures, start pressurizing the top of the tank and blow all the water out of the system. Once it's dry, put about 20 lbs. of pressure in the tank and start up the pump. You should be good to go.
Q:Water pump spray height?
well water exerts about 1 atm pressure (15psi) for each 33 feet of depth so 300psi is about 10 atm meaning that your pump could support a column some 330ft high then figure what pressure you would need to make your spray effective and subtract 33ft per 15psi this is only a ballpark estimate losses in hoses will be significant
Q:well water pump questions...thanks?
too much pressure in your pressure tank bleed some air out. reset pressure.
Q:Do pond water pumps make noise?
majority of the pond pumps you get to day are extreamly quiet and wont bother the fish or you at all
Q:I'm looking for a salt water pump...?
If you live the ocean try the shipyard, or any ,were around dock...or online..
Q:How do I calculate water volume pumped?
You have already stated the volume as 8 gpm. There is an elevation head of 170 ft, a friction loss of 1 1/2 ft/100 ft at 8 gpm for and additional 30 ft. of head, You did not state what the service pressure was supposed to be at the delivery point. so the total head required of the pump will be 200 ft. or more if a pressure is desired. Add 2 1/3 ft of head for each psig of desired pressure. Because of hydrodynamic design limitations of the pump impellers, you will never find a centrifugal water pump for sale with that low volume combined with that high head. You will need a positive displacement water pump having an approximately 8 -10 gpm capacity at 200 ft head (87 psi) or more, depending on that pressure. You cannot lift water farther up than about 25 feet with any kind of pump because of the thermodynamic properties of water under negative suction pressure. Deep well pumps are lowered down into the well and submerged. The well may have been drilled 170 feet deep, but the water will probably have risen up into the casing. The actual depth of water may be much less than 170 ft. That will need to be measured You will need 3/4 horsepower as is and 1 hp with 20 psig of pressure at the delivery point.
Q:Is it the a hose or the water pump? ?
fill it , start it , watch it, see where its leaking, if you still can see it , see a mechanic, but dont over heat it , you could damage the engine
Q:Can a car water pump work at partial capicity or is a matter of it pumps or doesn't pump?
You got one of the money making shops. If you go for this they will give you a BIG bill and you will have the same water pump. Water pumps go bad when the mechanical seal fails and they leak. No other reason ---if it ain't leakin it ain't bad. The only way you could have a weak' pump would be a slipping belt and that would create an overheat problem. I don't know if you have a heating problem but if you ever do go to a RADIATOR SHOP not a rip off auto repair. Don't fall for the thermostat thing either--same scenario big bill--- same thermostat. Water pumps and thermostats don't cause overheat problems except in extremely rare situations.
