Abstract

The utility model discloses a pump body casting with a self-compensating sealing structure, which relates to the technical field of pump body castings and comprises a pump body casting body, wherein an annular plate is fixedly sleeved on the outer surface above the pump body casting body, two support rods are symmetrically and fixedly connected to the upper surface of the annular plate, a cover plate is jointly sleeved on the rod walls of the two support rods in a sliding manner, a sealing piece is arranged between the cover plate and the annular plate, clamping grooves are formed in two ends of the sealing piece, a rebound mechanism is arranged between the corresponding two clamping grooves, and two through holes are formed in the upper surface of the cover plate. According to the utility model, through the design of the first spring and the insert block of the rebound mechanism, when the sealing element is thinned due to friction and abrasion, the spring releases elastic potential energy to push the insert block to slide into the clamping groove, and the design of automatically compensating the thickness loss of the sealing element enables the sealing element to always keep a compressed state, so that the sealing element does not need to be replaced manually and frequently, and the maintenance cost is remarkably reduced.
