Abstract

The invention discloses polishing equipment for centrifugal pump parts, and relates to the field of centrifugal pump intelligent machining. The grinding equipment mainly comprises a first rotating shaft rotationally arranged on a rack, the first rotating shaft is externally connected with a driving source, a positioning mechanism for fixing an impeller to be machined is arranged on the first rotating shaft, a second rotating shaft rotationally arranged on the rack is arranged beside the first rotating shaft, a spray head unit for polishing a welding seam on the impeller is arranged on the second rotating shaft, the first rotating shaft and the second rotating shaft are connected through a transmission mechanism, and the transmission mechanism is used for controlling the spray head unit to move to align to welding seams on the impeller when the first rotating shaft rotates. According to the polishing equipment, the plurality of welding seams of the centrifugal pump impeller can be automatically polished in sequence, the geometric accuracy and the surface smoothness of the centrifugal pump impeller are improved, and the labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the field of intelligent processing of centrifugal pumps, and specifically relates to a grinding equipment for parts of centrifugal pumps. Background technique [0002] A centrifugal pump refers to a pump that delivers liquid by the centrifugal force generated when the impeller rotates. The impeller is the core part of the centrifugal pump. Its rotating speed is higher than that of the centrifugal pump, and the force is greater. The blades on the impeller play a major role. The impeller must pass the static balance test before assembly. The inner and outer surfaces of the impeller are required to be smooth to reduce the frictional loss of water flow. The blades of the centrifugal pump impeller are generally backward curved blades. There are two types of blades: cylindrical and twisted. The use of twisted blades can reduce the load on the blades, improve the suction performance of the centrifugal pump, and improve the anti-cav...
