At present, in the machine irrigation, the phenomenon of “unreasonable supporting of power†is prominent, which is mainly “big horse-drawn cars†or “small horse-drawn cartsâ€. For example, a 8B18A pump should be equipped with a 17-kilowatt motor, while some pumps are equipped with a 22-kilowatt motor according to the 8B18 type pump. If the annual operating time is 3,000 hours, it will consume more than 10,000 kilowatt-hours. The matching power is selected to be small, that is, the "small horse-drawn cart" will cause the lack of water pump output, motor overload or with no water pump, nor can it guarantee the safety and economic operation of the equipment. Therefore, the power of the power machine and the pump must be properly matched. In practice, the former is easy to handle; the latter, that is, the "small horse-drawn cart" is more complex and difficult to handle. Introduce the following experience for the operator to handle and deal with according to the actual situation: (1) When the power machine and the water pump are not matched properly, if the horsepower of the power machine is too small, the power machine corresponding to the high horsepower should be replaced. (2) If the pump speed is too high (after the pump speed increases, the horsepower ratio is relatively high), and if the prime mover does not move the pump, the pump speed should be reduced. (3) The parts in the pump may be damaged, and the friction between the impeller and the pump shell may become severe or may not move, and the pump shaft may bend, the packing pressure may become too tight, and the bearing may be damaged. This will cause the power machine to not move the pump. At this time, it should be overhauled to eliminate various faults. (4) If the pump pump is not clean water, but contains a lot of silt of sewage, so that the shaft power increases (because the same volume of sewage is heavier than the clean water) and the power machine belt does not move. Therefore, general agricultural water pumps are not allowed to pump sewage. (5) Because the inlet surface changes too much, when the water rises very high, the pump water output increases, the load also increases a lot, and may eventually be brought to a standstill. At this time, the outlet valve should be closed or the water output should be reduced, and the shaft should be reduced. power.
