The invention discloses a centrifugal pump mechanical seal washing device comprising a centrifugal pump body, a first mechanical seal and a second mechanical seal. A water outlet pipe is arranged in the middle of the upper end of the centrifugal pump body. A cyclone hydraulic separator is connected to the side edge of the water outlet pipe through a water conduit. The lower end of the cyclone hydraulic separator is connected to the upper end of a connecting barrel through a pipeline, and the pipeline communicates with a connecting barrel inner cavity. The surface of the first mechanical seal is provided with a spiral diversion groove. The first mechanical seal is also arranged in the inner cavity of the connecting barrel and is located on the left side of the connecting barrel. The secondmechanical seal is fixedly connected to the left end of the connecting barrel and comprises a first inserting-connecting barrel, a second inserting-connecting barrel and an end cover disc which are formed integrally, are arranged from right to left, and are increased sequentially in diameter. The first inserting-connecting barrel is connected in an inserting-connecting opening formed in the left end of the first mechanical seal in an inserted mode. The centrifugal pump mechanical seal washing device has a circulation filtration effect on washing liquid, blocking of the washing liquid is prevented effectively, assembly of the first mechanical seal and the second mechanical seal is convenient, and disassembly operation is simple.
Description
technical field [0001] The invention belongs to the technical field of a centrifugal pump mechanical seal flushing device, and in particular relates to a centrifugal pump mechanical seal flushing device and a manufacturing process thereof. Background technique [0002] Mechanical seal is an important form of shaft seal in centrifugal pump equipment. The high-speed rotation of the pump will cause high temperature on the dynamic and static sealing surfaces of the mechanical seal. The mechanical seal flushing system lubricates and cleans the dynamic and static sealing surfaces of the mechanical seal by flushing the mechanical seal. cool down. [0003] The existing mechanical seal flushing device cannot filter the liquid used for flushing well, so that the flushing liquid is easily blocked on the mechanical seal, which is not conducive to flushing and cooling. At the same time, the disassembly and installation of the mechanical seal is inconvenient, which is not conducive to dis...
