Dalian centrifugal pump production

centrifugal pumpThe function of the pump seat, the function of the horizontal centrifugal pump pump seat, and the function of the centrifugal pump pump seat are to support and fix the pump casing, usually cast together with the pump casing. The centrifugal pump seat has flange holes for fixing with the base plate or foundation. The top of the pump casing is equipped with water filling and air release screw holes for easy accesswater pumpUsed to fill water and remove air from the pump casing before starting. There are screw holes for installing vacuum gauges and pressure gauges on the suction cone tube and pressure cone tube of the water pump. There is a drainage screw hole at the bottom of the pump casing, which is used to drain the accumulated water inside the pump casing during the shutdown and maintenance of the water pump. In addition, there are drainage screw holes at the bottom of the transverse groove of the pump casing. If not in use temporarily, threaded plugs (also known as blind plugs) can be used.

Among the above components, the impeller and pump shaft are the rotating parts of the centrifugal pump, while the pump casing and pump seat are the fixed parts of the centrifugal pump. There are three connecting parts between the rotating and fixed parts. That is, the shaft sealing device between the pump shaft and the pump casing is called a packing box, and the leakage reduction device at the joint between the impeller and the inner wall of the pump casing is called a leakage reduction ring; The rotational connection device between the pump shaft and the pump seat is called a bearing seat.
