Centrifugal pump mechanical seal repair skills

Centrifugal pump mechanical seal repair skills I. Introduction Mechanical seal itself is a demanding precision parts, the design, machining, assembly quality has high requirements. When using the mechanical seal, the factors that affect the performance of the mechanical seal should be analyzed. The mechanical seal should be applied to the technical requirements and medium requirements of the pump, and have sufficient lubrication conditions, so as to ensure the long-term reliable operation of the seal. There are four channels of A, B, C, and D possible for the fluid in the mechanical seal shown in Figure 1 to leak. Second, the maintenance skills In the actual production operation, due to maintenance reasons, the problem of machine type selection and other uncertainties, often cause centrifugal pump leaks in operation, even in severe cases downtime, threatening production operations. In general, the shaft seal leaks are: dynamic and static end face, between the moving ring and the sleeve, the static ring and the ring seat between the sleeve and the spindle in Figure 1, between the gland and the body . Centrifugal pump leakage of this machine seal, a serious impact on pump performance, increase the frequency of centrifugal pump maintenance, increase equipment spare parts consumption. Therefore, in order to improve the life of machine seal, pay attention to several points in the maintenance. 1. Precautions for Disassembly When disassembling the mechanical seal, it is forbidden to use hand hammer and flat shovel to avoid damaging the sealing element. If there is a mechanical seal on both ends of the pump, care must be taken in the disassembly process to prevent loss. (Centrifugal pump mechanical seal repair skills)
