Power machine with fixed pump approach
At present, in the irrigation system, the phenomenon of "unreasonable power supply support" is prominent, mainly "big horse pull cart" or "small horse pull cart." Such as an 8B18A type pump should be equipped with 17 kilowatts of motor, while others are by type 8B18 pump to the matching 22 kilowatts of motor, if the annual work of 3000 hours, to consume more than 10,000 kilowatt hours. A small matching power, that is, "small horse drawn cart," will result in insufficient water pump, motor overload or with fixed pump, it can not guarantee the safety of equipment, economic operation. Therefore, the power machine and pump power must be matched with reasonable. In practice, the former is easy to handle; the latter is more complex and difficult to handle. This special introduction of our pilot experience for the hands of the actual situation according to maintenance treatment. (1) When the power machine and the pump are improperly matched, the horsepower of the power machine should be replaced with the correspondingly larger power machine. (2) If the pump speed is too high (due to pump speed increases, the horsepower is relatively high than the establishment of square), the original power with fixed pump, pump speed should be reduced. (3) Pump parts may be damaged, the impeller and the pump shell friction or stuck stuck, the pump shaft bending, packing too tight, bearing damage and so on, will make the power machine with fixed pump. At this time should be thoroughly overhauled to eliminate all kinds of faults. (4) If the pump is pumping water instead of clean water, but with a large amount of muddy water, the shaft power is increased (because the same capacity of sewage than water) lead to power plant fixed belt. Therefore, the general agricultural pumps are not allowed to pump sewage. (5) due to changes in the water surface is too large, when the water rises very high, the pump water increases, the load also increased a lot, and finally may not move, this time should be out of the water gate valve or reduce the amount of water to reduce the shaft power.
