Q:What are the uses and precautions of magnetic pumps?
2, when the suction surface above the pump axis, before starting the valve can open the suction pipe, if the aspiration level below the pump axis, the pipeline to be equipped with bottom valve;3, the pump should be checked before use, the motor blade rotation to be flexible, no jam, no abnormal sound, the fasteners should be tightened;4 、 check whether the motor rotation direction is consistent with the magnetic pump steering mark;
Q:If you use an ordinary 15W submersible pump, put it in the tank, if the leakage, the fish will hang it?
If the fish tank is made of metal, the fish tank is grounded or connected to the zero line, and then the fire line is put into the water, then your fish will be electrocuted immediately. Go back to the submersible pump, submersible pump line and the zero line very close, even if the firing line and the zero line at the same time the leakage occurs, fish could not swim between the firing line and the zero line, so the tank submersible pump leakage will cause the following hazards: 1, electric shock. 2, submersible pump short circuit. 3, the submersible pump serious fever, resulting in water temperature tank.
Q:What is pump suction work?
Pumping loss refers to the loss of work done by the piston of the engine in the pumping process compared with the theoretical cycle. Theoretical pump Qigong to remove the loss of pump gas after the actual pump qigong.
Q:Direct connection pump What is straight pump and non direct pump? What's the difference in structure?
The direct connected pump impeller is directly mounted on the motor shaft, and the non direct connected pump and motor are two shafts, and the two shafts transmit torque through the coupling
Q:What are the general water pump failure, how to repair?
Troubleshooting of water pumpFirst, the water pump does not cause water analysisThere is air in the inlet pipe and pump body(1) before the water pump is started, the water is not filled enough. Sometimes it seems that the water has been discharged from the vent hole, but the pump shaft is not rotated. The air is completely discharged, resulting in a small amount of air remaining in the inlet pipe or pump body.
Q:What are the failures and causes of the replacement of the fuel pump assembly?
Failure cause:1) the gasoline pump is too thick with the gasket at the junction of the axle box.2) pump film rupture or pump film and pump shell combination of sealing is not strict.3) the oil inlet valve is stuck or sealed badly.4) severe wear of the rocker arm, reducing the pump film stroke.5) the pipeline from the gasoline tank to the gasoline pump is not smooth, or the pump film spring passes.
Q:Does the control cabinet of the fire control pump need to be related to the fire control room?
The relationship is simple, the fire pump is pressurized water supply device, the control cabinet is the power supply for the fire pump, the regulator tank is to stabilize the pressure of the network management, reduce the pump frequently start device.
Q:What kind of motor does the hydraulic pump need?
The motor should be determined according to the work environment, such as 220V.12V.24V.72V or 380V, and then the power.Calculation of actual oil pump power:
Q:Hydraulic pump displacement refers to the pump shaft what?
You can see the sign of your hydraulic pump. There will be a displacement **ml/r in the sign of the hydraulic pump (r stands for every turn, ML is milliliter)
Q:How to select the fire pump?
Such as a large pressure of about 10m or about 0.1MPa} because the most unfavorable point fire hydrant requires more than 0.07MPa (7m) and 0.5MPa (50m) is not greater than the pressure, so unless the pump is located in the 50m Valley is still lower than the garage, or add to the valve (or the use of fire hydrant decompression) otherwise, it is 120m lift pump
