Q:A pump, the flow rate of 30T/H per hour, lift 30 meters, should be allocated more power motor?
Depends on how big your water pump is. How long is the pipe length?
Q:Sewage treatment plant design how many pumps should be selected, head how to calculate the maximum design flow is 833M3/h
Is the sewage treatment bar, you have to choose corrosion-resistant pump, sewage treatment lift is generally not high, and then you flow so much, the choice of axial flow pump is the best choice, specific models only you go online to check. The information I provide is the choice of corrosion resistant axial pumps. Then, if there is impurities, it is best to use the axial flow pump with mixing function.
Q:The diving pump in the aquarium stops and stops on the goldfish
The submersible pump has been on all the time.
Q:The reason why the pump is overloaded
Main reasons: 1. bearing lubrication is not good or bearing quality problems appear peeling phenomenon, resulting in increased resistance to pump operation.2., the pump cover and impeller clearance is too small, the impeller mouth and pump cover friction.3 belt tight, resulting in heavier load.4. centrifugal pump power is proportional to the flow, the greater the flow, the greater the power needs, large, low head flow, resulting in heavy load.Water pump maintenance: 1., water pump to do routine maintenance, check the water seal every day, to prevent water damage, water directly into the bearings, accelerated wear and tear.2. belt adjustment should be appropriate, not too loose, too tight.3. strictly according to the standard operation, for the low lift pumping load, it is necessary to control the flow by throttling, thereby reducing the load.
Q:Water pump eliminates air
Because the pump is rotated to the water from the center of the impeller thrown out, while the water inlet has been filled recently. If there is air, water can not be pumped out
Q:1.5KW water pump caliber is 40, what is the flow rate?
Because you provide a wide range of data, there are several models and lift and flow, if you are interested, please leave a message for me to communicate
Q:Why is water pumping cool water is normal, but when pumping hot water pressure and flow are very small?
Not sure about the LZ what is the specific type of hot water pump pump but it is flow and small pressure must be produced liquid vaporization of liquid vaporization two general situation is the pump pressure alternating is under positive pressure immediately into negative pressure is two high temperature liquid into the pump and to absorb mechanical heat due to the higher temperature is the centrifugal pump if so when the liquid from the inlet to the outlet end of the impeller is thrown when in the state of negative pressure and lower boiling point even if did not reach 100 degrees will boilIf the water pressure and flow rate of small vaporization significantly not only reach the requirement of the pump itself also has a lot of damage caused by mechanical damage is suggested to view the instructions to use if this situation is to contact the dealer in the allowable range of temperatureIf no water is not only the problem of vaporization conditions can be detected under normal pressure inlet check instructions when pumps are used in the allowed suction height within the position and I don't know if the pump there may be no open suction valve or discharge valve and pump parts prior to use at the beginning of irrigation is the first inside in order to produce self suction irrigation
Q:My fish tank pump is deep enough, it doesn't bubble up. Without oxygen supply, but it can filter. Does it damage the pump itself?
First tell you the pump not bad, just can't carry oxygen rinse, now he is equivalent to a 2 in a filter of the submersible pump, without any damage to the pump itself, three in one pump is actually in the 2 water outlet and air pipe, pressure by fluid flow is the principle of position the smaller the air drag, now a large pressure, oxygen loss of function, but the pump itself, his work without any change, so do not burn, rest assured it
Q:What kind of water pump does the 5.5KW motor have?
Model has: QS-250-40-21, lift 21m, flow 40 square, motor power is 4KW, water pump diameter is 232cmQJ-200-40-26, lift 26m, flow 40 square, motor power is 5.5KW, water pump diameter is 189cmYou can choose the right pump according to your well path.
Q:What is the function of the pump?
Pumps are usually used to enhance the liquid, conveying a liquid or liquid to increase the pressure, that is the original motive of the mechanical energy so as to achieve variable liquid fluid energy machine called pump.The technical parameters of measuring water pump include flow, suction, lift, shaft power, water power, efficiency, etc. according to different working principles, they can be divided into volumetric pump, vane pump and so on. Displacement pump is to use its studio volume changes to transfer energy; vane pump is to use the rotating blade and water interaction to transfer energy, there are centrifugal pumps, axial flow pumps and mixed flow pumps and other types.
