First, the classification of clean water pump:
Orchard single-phase water pump is divided into self-priming pumps, water-filled pumps and submersible pumps, the selection principle is:
1, self-priming clear water pump: the water quality is relatively fixed working position, suction pipe within 3.5 meters of the pipeline stable, water supply wells, orchards irrigation can reduce pump water when filling trouble, the actual lift below 22 meters, Less efficient chemical pump. When put into operation for the first time, you should first join the circulating emptying water, the pump can complete self-absorption.
2, water-filled clean water pump: good water quality of the water pipeline is relatively fixed, suction 2.5 meters within the actual lift of 32 meters, the pump flow can be adjusted according to needs, to adapt to species of specialized households for spraying pesticides, irrigation and water supply, work More efficient. Suction pipe should ensure good sealing.
3, submersible clean water pump: adequate water head low, the valve is suitable for large irrigation of farmland orchard water. Submersible pump into the water because of the work of the axial push water increased, reducing the amount of water will increase the pump load. So do not install the submersible pump outlet valve to prevent the valve is turned off because the pump resistance is too large resistance to burn the motor.
Second, the correct use of water pump:
1, the use of clean water pump should pay attention to: the voltage is consistent with the electricity safety, because the water pump is working in wet conditions, the power switch should be installed before the leakage protection switch.
2, do not move when the pump work, suction pipe vertically into the water at the end of the valve 0.4 meters.
3, poor water quality should be set up filters to prevent debris sucked into the pump affect the pump operation.
Third, the pump troubleshooting methods:
Water pump is the motor and pump into the whole, the motor rotor fulcrum bearings and pump bearings, a rigid power transmission to the pump impeller rotation work pressure reducing valve. Only between the pump impeller and the vortex shell 0.10-0.22 mm gap, debris grit easily stuck impeller, the motor rotor can not rotate and failure. From the repair pump failure analysis due to the impeller stuck motor damage accounted for more than Bacheng. When turning off the power switch, if the motor does not turn on, turn off the power in time, and the motor will generate a rotating magnetic field by the inductor. The motor will not be damaged in a short time. You can use a screwdriver to remove the motor cover, rotate the fan left and right hand until the flexible back cover and then power.
