Agricultural pump installation and troubleshooting
The technical requirements for the installation of agricultural water pumps are very strict. First of all, the base of the pump should be firm and the length of the suction pipe should be as short as possible. Second, the inlet pipe should be sealed and reliable. The bottom valve and the hose are fastened with a safety rope. If the water source is a channel, the bottom valve should be more than 0.5 meters above the water bottom, and the screen should be added to prevent debris from entering the pump. The third is when the belt of the pump is driven, the tight edge of the belt should be down to improve the transmission efficiency. The pump impeller steering should be consistent with the direction of the arrow. Check the pump should pay attention to three points: (1) The pump shaft should be able to flexibly rotate, no impact sound; the pump shaft radial no obvious shaking, need to add enough oil. (2) Check whether the water inlet hose is damaged, and if it is cracked, repair it in time. Check for loosening of the fastening bolts. Tighten the loose bolts. (3) The motor windings and cable insulation of submersible pumps must meet the requirements before they can be used. Troubleshooting methods: (1) Do not absorb water or water, mostly due to bottom valve stuck, filter part of the silt; the height of water absorption is too high or leakage of suction pipe; and the impeller flow channel blocked due to the corresponding should be taken Solution. (2) Leakage or air leakage in the pipe may be caused by bolts being not tightened during installation. If the leakage is not serious, you can apply grout in places where it leaks or leaks, and tighten the nut with a wrench; if it leaks seriously, reinstall it. (3) Severe vibration of the water pump may be caused by unbalance of the electric rotor, poor coupling of the coupling, wear and bending of the bearing, looseness of the rotating parts, breakage of the rotating parts, or inability of the pipe support. It should be adjusted, reinforced, straightened or replaced depending on the circumstances.
