Abstract

The invention belongs to the technical field of nuclear fluid mechanical seals of nuclear power stations, and particularly relates to a device for mechanical seal disassembly and assembly and a disassembly and assembly method thereof. The device comprises a handle, a jackscrew, a large disc, bolts, L-shaped annular draw hooks, a small disc, a press-fit sleeve, nuts and screw rods. The device is simple in structure and convenient to operate, and cannot damage mechanical seals, and the problem that mechanical seals are difficult to assemble can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of nuclear-grade fluid mechanical seals in nuclear power plants, and in particular relates to a device for disassembling and assembling mechanical seals and a disassembling and assembling method thereof. Background technique [0002] The mechanical seal is an axial end face sealing device that relies on elastic elements to preload the dynamic and static ring end face seal pairs and press the medium pressure and elastic element pressure to achieve sealing. It is a very important and very precise nuclear grade fluid machinery in nuclear power plants. One of the parts of the equipment needs to be replaced several times periodically during the service period of the equipment to ensure the safe and reliable operation of the equipment. The mechanical seal moving ring is installed on the shaft sleeve, and the threaded pump cooperates with the shaft sleeve and the moving ring respectively. There are two O-rings on ...
