Orchard single-phase water pump with small size and light weight, flexible, versatile and adaptable features, in recent years by farmer and fruit specialized households welcome. Due to the user's understanding of the structural characteristics and operating characteristics of single-phase water pump, select and use some problems in the water pump I do not know how to rule out, can solve their own glitches and repair or even improper operation of the pump motor damage. Some kinds of fruit specialized households orchards spraying pesticides to worry about liquid spray nozzle, the pump to limit the amount of water and increase the pump motor load or damage to the motor. Reasonable choice and use of clean water pump, master operating technology is the key. 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 pipe within 3.5 meters of stable, Used in the well water supply, orchard irrigation can reduce the water pump trouble, the actual head of less than 22 meters, less efficient. 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: full of low water head, 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, 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 pump as a whole, the motor rotor fulcrum bearings and pump bearings, a rigid power transmission to pump impeller rotation. 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. Four, self-absorption, water-filled pump outlet pipe 0.5 meters to install the valve, the valve should choose the ball valve, which will help reduce water resistance, increase the amount of water pump pressure. Fifth, clean water pump for spraying pesticide pressure pump, the best combination of three or four centrifugal nozzle, this nozzle atomization performance is good, nozzle pressure 1.6-3.5 kg / cm. Water pump pressure in the 1.2 - 3.6 kg / cm2, the pressure to adapt to each other to save energy while also improving production efficiency, good pest control effect.
