[0036] The specifications of the cylinder body are: the diameter of the front section is 120mm; the diameter of the rear section is 155mm; the total length is 175mm; the specification of the piston is: the front thread M36×3, the diameter of the second section is 49mm, the diameter of the third section is 57mm, and the diameter of the disc is 155mm ; Hydraulic front thread Z3 / 8, inner diameter 4 mm, outer diameter 17.5 mm, length 310 mm; screw M10×1.5, length 130 mm.

[0037] Since the centrifugal compressor and the power machine connected to it are quite heavy, it is extremely difficult to assemble and disassemble manually, which is labor-intensive and labor-intensive, and it is easy to cause coupling deformation, or there is a certain stress due to the misalignment between the compressor and the power machine. These will make the compressor work abnormally. The above-me...

Abstract

The invention provides an assembling and disassembling tool of a coupler. The tool is characterized by comprising a cylinder, a piston, a hydraulic connecting tube, a gasket, O-shaped rings and an outer hoop, wherein the cylinder is formed by connection of a small front hollow cylindrical part and a large rear hollow cylindrical part through a middle section in a hollow truncated cone shape; the front part of the cylinder can be closely matched with the coupler; the piston is arranged inside the cylinder, the outer surface of the piston is similar to the inner surface of the cylinder, and the piston is closely matched with the front and rear parts of the cylinder through the front and rear O-shaped rings; and the hydraulic connecting tube is arranged at the center of the piston. A connecting opening is formed in the middle section of the cylinder, and a gap which can be filled with hydraulic oil is formed between the middle section of the cylinder and the piston. A low-pressure pump connecting opening is formed in the middle section of the cylinder, and the rear end of the hydraulic connecting tube is connected with a high-pressure pump connecting opening. The invention further provides a method for assembling and disassembling the coupler with the tool. When the tool and the method are used for assembling and disassembling the coupler, the heavy manual labor can be omitted, and the coupler can be assembled and disassembled safely and stably, so that the tool and the method have good technical effects.

Description

technical field [0001] The invention belongs to the technical field of devices for connecting or assembling shafts, and in particular relates to an assembly and disassembly tool and an assembly and disassembly method for assembly and disassembly of a shaft coupling of a centrifugal compressor. Background technique [0002] When the centrifugal compressor is installed and used, it is necessary to use a coupling to connect and fix the power machine. In the workshop or work site, in order to make the high-speed rotating compressor and the power machine run synchronously and stably, it is not only necessary to make the compressor shaft and the power machine Shaft alignment; but also easy assembly and disassembly. Considering that centrifugal compressors and power machines (such as electric motors) are often very heavy, it is not only difficult to assemble and disassemble them manually; it is also easy to cause mechanical deformation and damage to components including the rotatin...
