Working principle of mining centrifugal water pump
The mining centrifugal water pump is mainly composed of impeller, pump, pump casing, shaft seal and sealing ring. The pump casing must be filled with liquid before the centrifugal pump is started. When the prime mover drives the pump shaft and the impeller to rotate, the liquid moves in a circular motion with the impeller on the one hand, and is thrown out from the center of the impeller to the periphery under the action of centrifugal force, and the liquid is thrown from the impeller. Gain pressure energy and speed energy. When the liquid flows through the volute to the discharge port, part of the velocity energy will be converted into static pressure energy. When the liquid is thrown from the impeller, the central part of the impeller creates a low pressure zone, which forms a pressure difference with the pressure of the suction liquid surface, so the liquid is continuously sucked in and discharged at a certain pressure.
Working principle of self-balancing mining centrifugal water pump
The self-balancing centrifugal water pump for mining is a horizontal segmental multistage centrifugal pump with single suction or double suction inlet. The suction port of the pump can be vertically upward or horizontally, and the discharge port can be arranged vertically upward. Mainly include: inlet section, middle section, outlet section, secondary inlet section, positive guide vane, reverse guide vane, positive impeller, reverse impeller, shaft, throttling, pressure reducing device, stop sleeve, bearing body, transition pipe, etc. Components; the middle section is connected by high-strength bolts and the inlet and outlet sections. The sealing surfaces between the inlet section, the middle section and the outlet section of the pump are all hard sealed with molybdenum disulfide grease metal surface; the rotor is installed on the shaft The positive impeller, throttling and pressure reducing device, reverse impeller, bushing and other parts of the bearing adopt "solid-swimming" dry oil lubrication structure, the drive end adopts cylindrical roller bearing, and the end adopts angular contact ball bearing; the pump's working room It is composed of inlet section, middle section, outlet section, secondary inlet section, positive guide vane, reverse guide vane, transition pipe, etc.
The shaft of the self-balancing centrifugal water pump for mines rotates under the drive of the motor to work on the liquid and increase its energy, so that the required amount of liquid is passed from the suction pool through the inlet section, positive impeller, positive guide vane, middle section, and middle section of the pump. After the horizontal water outlet, transition pipe, secondary water inlet section, anti-impeller, anti-guide vane, and vertical water outlet of the water outlet section, the liquid is continuously sent out.
