How to ensure the normal use of agricultural pumps during spring irrigation? On February 16th, Pingdingshan City Agricultural Machinery Bureau reminded farmers that their friends should be properly maintained. The installation of the pump unit should be precise and reliable, and there should be no obvious vibration during operation. If the pump pump has abnormal noise or the bearing is hot (temperature is higher than 60°C) and the water leakage from the seal of the pump shaft is greater than 60 drops per minute, the cause must be ascertained and the fault must be corrected. Routinely screwed screws, such as packing gland screws, irrigation plugs, etc., apply appropriate wrenches, reasonable torque disassembly, do not screw with hand clamps, to prevent screw or nut slip; other screws, can be wiped on the top Some lubricating oils or regular rags are used to wipe rust-proof. If the bleeder screws are not commonly used to rust, they should be unscrewed first. Apply some oil and white lead oil to the threads, and change them two or three times a year. Pumps lubricated with oil should be changed once a month; lubricated with butter every six months. It should be noted that calcium-based greases for pumps and sodium-based greases for electric motors should not be used to make mistakes. Due to the hydrophilic nature of the sodium grease, water will emulsify into a foam to dissipate on the water pump, while the calcium-based grease is afraid of high temperature, used in the motor, easy to change after the temperature rises. Can not pump too much water, so as to avoid premature wear of the impeller, mouth ring and shaft, but also to prevent water shortages. Water shortage operation will damage the water seal, and it is prone to leakage of the water pump or even no water. After the drainage and irrigation season is over, the water pump must be carefully cleaned and inspected, and parts that are damaged or deformed and cannot be used should be promptly repaired or replaced.
