The details that should be paid attention to when starting the mining multi-stage pump
What details should be paid attention to when starting the pump
(1) Check electrical equipment, instrumentation and knife switches according to operating regulations.
(2) Check whether the motor is in good condition and measure the motor insulation resistance.
(3) Check whether the fixing bolts at various parts are loose or missing, check whether there is any sundries around the stainless steel centrifugal pump that hinder the start-up operation, and check whether the motor is grounded firmly.
(4) Check whether the rotation of the motor is consistent with the rotation of the pump.
(5) Check whether the inlet and outlet valves are flexible and easy to use, and open the inlet valve, close the outlet valve, check whether the pump seal packing leaks, and open the vent valve to confirm that the pump is filled with water and air is drained before closing the vent valve .
(6) Disc pump 3 to 5 turns, check whether the pump and motor rotate flexibly, listen for noise, use a crowbar to move the pump back and forth to check whether the pump displacement is qualified.
(7) Check whether the coupling is intact, whether the shield is firm, and whether there is any deflection.
(8) Check whether the liquid level of the large tank meets the requirements for starting the pump.
(9) Water injection stations and large-scale oil delivery stations should check the lubricating oil equipment and cooling water system and adjust them to normal working conditions.
(10) After everything is ready, contact the relevant department (post) to prepare to start the multi-stage pump for mining.
