First, to check whether the various parts of the equipment bolts are complete, with or without loose, to ensure the safe operation of the pump. Second, to check whether the power machine is safe and effective. When using a diesel engine, check whether the cooling water, lubricating oil, etc. are missing, and whether the operation condition is normal. If the motor is used, check whether the line erection and connection meet the safety requirements, whether the grounding line is reliable, whether the motor is wet, and whether the circuit is in good condition. Electric shocks occur and electricity safety is ensured. Third, to check whether the power unit, the installation is firm. Pay attention to check whether the drive connection between the power machine and the water pump is standardized, safe and reliable, and whether the drive connection is equipped with safety protection facilities, such as protective plates, protective nets, etc., to avoid dangerous accidents.
