Before use "three inspections" Check all parts of the equipment to check whether all parts of the bolts are complete or loose, so as to ensure the safe operation of the pump. Check whether the power machine is safe and effective use of diesel engine, should check the cooling water, lubricating oil, etc. is missing, the operation is normal; use the motor, should carefully check the line erection, connection is consistent with safety requirements, grounding line is reliable, the motor is wet, Whether the circuit is in good condition to prevent electric shock accidents and ensure the safety of electricity. Check whether the power of the unit is matched, and whether the installation is firm. Check whether the drive connection between the power machine and the pump is standardized, safe and reliable. Whether the drive connection is equipped with safety protection facilities, such as protective plates, protective nets, etc., to avoid dangerous accidents. When used "three wants" Do not install the vibrating pump. The installation of the pump set must be accurate and reliable. There must be no obvious vibration during operation. If the pump pump has abnormal noise or when the bearing is hot (temperature is higher than 60°C) and if the seepage of the pump shaft is more 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 for reasonable torque disassembly, do not use hand-clamping to prevent thread or nut sliding; other screws, can be applied to the above Lubricant or regular rags are used to wipe off rust. If the drain screws are not commonly used to cause rust to die, they should be unscrewed first. Apply some oil and white lead oil to the threads and change them every year for 2 to 3 times. To scientifically lubricate pumps that are lubricated with oil using oil, lube oil should be replaced 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. Do not avoid emptying and not pumping sand. Do not pump water with too high sediment content to avoid premature wear of impellers, rings, and shafts. Try 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.
