Classification of clear water pumps:
The orchard is divided into single-phase water pump self-priming pump, water pump and submersible pump, selection principle:
1. Self suction water pump: water quality is relatively fixed working position, suction in 3.5 meters pipeline stability, can reduce water pump in water and living water supply, irrigation in orchard with water filled trouble, actual lift is 22 meters in the following, the work efficiency slightly worse chemical pump. The first time put into operation should be added to the circulating water, the water pump to complete the self absorption.
2. The water filling type clear water pump: water quality good mobility pipeline relatively fixed, suction 2.5 meters the actual head in 32 meters, water pump flow can be according to arbitrarily regulate, to adapt to the mango specialist for spraying pesticide, water supply, irrigation, high work efficiency. Water suction pipe should ensure good sealing.
3. Submersible water pump: water supply sufficient head low, the valve is suitable for irrigation of farmland orchard water. Due to submersible pump into the water to work in the axial push up water, reducing the amount of water will increase the pump load. So do not install the valve on the water outlet pipe of the submersible pump, prevent the valve closed on pump resistance is too large to burn out the motor.
