Clean water pump classification and correct use

First, the classification of clear water pump:

Orchard single-phase clean water pump is divided into self-priming water pump, water-filled water pump and submersible water pump. The selection principle is:

1. Self-priming clear water pump: The water source is of good quality and relatively fixed working position. The suction pipeline is stable within 3.5 meters. It can be used to reduce water pumping trouble when water supply for living wells in orchards or irrigation is performed. The actual lift is less than 22 meters. The working efficiency is slightly worse chemical pump. When it is put into operation for the first time, it should be added to the circulation to empty the water before the pump can complete self-priming.

2. Water-filled clean water pump: good water quality The large mobile pipe is not fixed. The actual lift within 2.5 meters is within 32 meters. The pump flow can be arbitrarily adjusted according to the need. High efficiency. Suction hoses should ensure good sealing.

3, submersible clean water pump: low water supply sufficient head, the valve is suitable for irrigation of farmland orchard water. As the submersible pump is pushed into the water to increase the axial pushing water, reducing the amount of water will increase the pump load. Therefore, do not install the valve in the outlet pipe of the submersible pump, so as to prevent the motor from being damaged because the valve is closed.

Second, the correct use of clean water pump method:

1. Clean water pump should pay attention before use: voltage match and electricity safety, because the clean water pump is working in a humid environment, before the power switch should be installed on the leakage protection switch.

2. Do not move the pump when it is working. Put the bottom valve of the suction pipe vertically into the water for 0.4 meters.

3. When the water quality is poor, a filter should be set to prevent the sundries in the water pump from affecting the pump operation.

Third, the pump troubleshooting method:

The clear water pump is an integral part of the motor and the water pump. The fulcrum bearing of the motor rotor is also a water pump bearing. The rigid power transmission makes the water pump impeller rotate the pressure reducing valve. There is only a gap of 0.10-0.22 mm between the impeller of the water pump and the eddy current shell. The debris can easily catch the impeller and cause the rotor of the motor to rotate and fail. From the failure of repairing the water pump, the motor rate accounted for more than 80% due to the jamming of the impeller. When turning off the power switch, if it is found that the motor does not turn, turn off the power in a timely manner. When the motor is working, a rotating magnetic field is generated by the inductor, and the motor will not be damaged in a short time. You can use a screwdriver to remove the rear cover of the motor and rotate the fan blades left and right by hand until the rear cover is flexibly replaced and then powered on again.
