Q:How to select the pump model?
Pump selection parameter:1, lift, if the head is large, the use of multi-stage vertical centrifugal pump, if the head is small, the use of horizontal axial flow centrifugal pump2. Displacement3, suction stroke, if the suction range is short, select the submersible pump, suction distance, select centrifugal pump
Q:A pump, the flow rate of 30T/H per hour, lift 30 meters, should be allocated more power motor?
Mgh=ptIn 1 hours30*1000*10*30=p*3600P=2500 (W)Therefore, the ideal state should be more than 2500W motorWith all kinds of losses, it is recommended to configure more than 3000W motors
Q:Pump adapter joint net outside tube, what is the principle?
At once the room after the fire, the internal fire pool once water shortage, the water tank can be within the fire truck hit the water chamber through the pump adapter connected to the fire extinguishing effect.
Q:55KW how large is the water pump wiring?
Transmission within 100 meters, 70 square millimeter aluminum cable, or 50 square millimeter copper cable. If you exceed 100 meters, you'll have to add a number to the cable.
Q:50 meters deep well with what water pump: home?
For deepwater submersible pumps, ordinary submersible pumps are inefficient.
Q:Why should we pump water into a pump when the country uses a pump to pump it?
Because it is not a self-priming pump, so add water, otherwise there is no pressure can not afford
Q:Why does the pump head decrease when the pump flow rate increases?
First of all, the power of the pump is determined by the motor. When the power is certain, work must be done. According to w=mgh, the flow determines mg, the head is h, you think, if the flow rate is large, is the head smaller?. This is theoretical, and at the same time, you see, the water pump characteristic curve can also see that the flow rate increases, the corresponding smaller head.
Q:Why is the minimum liquid temperature allowed at 2 DEG C instead of 0?
Is zero freezing?
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:What are the commonly used tools for repairing water pumps?
This universal table is necessary, there is an insulation resistance meter, with some 8 six angle screws, as well as a common pump mechanical seal, you can also enter some of the water pump cable
