Starting Method and Procedure of Mine Submersible Pump

Mining submersible pump start-up methods and steps which?
Mine submersible pump with bottom valve should first open the irrigation valve and the release valve, the pump irrigation, the pump body to know the air all the discharge, and then close the irrigation valve and release valve; if the end of the valve drain pump should be Start the vacuum pump or jet pump, mining submersible pump price pump body, suction tube to a certain degree of vacuum, in the stop. The use of positive pressure drainage, should first open the inlet valve, and then open the release valve, until the vent valve to see the water vent, close the release valve.
Start the motor
(1) Before starting high-voltage equipment must wear insulated gloves, wear insulated boots.
(2) Rat-type motor directly start, first close the power switch, the current reaches normal, open the pump outlet valve.
(3) Wound-type motor starts, the first slip of the motor slip ring to the starting position of the handle, starter handle in the stop position, close the power switch, to start the current gradually down, the gradual removal of starting resistance , So that the rotor short circuit, and the electric motor slip ring hit the running position, the use of electric motors hit the normal speed, mine will eventually pull the trigger lever stop position.
