Water pump classification profile

First, the orchard single-phase water pump is divided into self-priming pumps, water-filled pumps and submersible pumps, the selection principle is:
Self-priming clear water pump: water quality is relatively fixed working position, suction within 3.5 meters of the pipeline stable, water supply wells, orchards irrigation can reduce water pump trouble, the actual head of less than 22 meters, the working efficiency Slight chemical pump. When put into operation for the first time, you should first join the circulating emptying water, the pump can complete self-absorption.
Water-filled clear water pump: good water quality and good mobility of the 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 professional households spraying pesticides, irrigation and water supply, work efficiency high. Suction pipe should ensure good sealing.
Submersible clear water pump: adequate water head low, the valve is suitable for large irrigation of farmland orchards. 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, clean water pump before use should pay attention to voltage and electrical safety, water pump is working in wet conditions, the power switch should be installed before the leakage protection switch. Do not move the pump work, suction pipe bottom valve vertically into the water 0.4 meters, poor water quality should be set filters to prevent debris sucked into the pump to affect the pump operation.
Third, the water pump is connected with the motor and the pump as a whole, the motor rotor fulcrum bearings and pump bearings, a rigid power transmission to the pump impeller rotary 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.
