What are the working principles and later operation and maintenance operations of industrial boiler burners oil pump?
1. Working principle of boiler burner oil pump: The boiler burner oil pump is a type of volumetric pump, composed of two gears, pump body and front and rear covers, forming two closed spaces. When the gear rotates, the volume of the side of the gear that is disengaged from the space decreases, forming a vacuum, sucking in liquid, and the volume of the space on the gear engage side decreases, squeezing the liquid into the pipeline. The suction chamber and discharge chamber are separated by the line of action of the two gears. The pressure at the discharge port of the boiler burner oil pump is completely determined by the resistance at the outlet. 2. Operation and maintenance operation method of boiler burner: 1. Start: (1) Check all pipe flanges and joints of the pipeline for seal. (2) Spin the coupling, no friction or collision sound. (3) Inject the transported liquid into the pump for the first time during startup. (4) Before starting, open the inlet and outlet valves of the pipeline completely, and do not start with closed valves. (5) After verifying the direction of rotation of the motor, start the motor. 2. Stop: (1) Turn off the electric motor. (2) Close the pump’s inlet and outlet valves.
