Working principle: a reciprocating compressor primary cylinder piston installation tool influences the installation quality of a unit if the installation operation quality of a piston of a reciprocating compressor meets requirements, and the installation efficiency influences the maintenance progress node of the unit. Aiming at the technical requirements of piston installation operation: 1. the piston is ensured to always keep the correct position in the installation process; 2. in the process of piston installation, the piston ring and the supporting ring are attached to the ring groove and do not deform by extrusion with the rabbets of the ends of the cylinder body and the cylinder sleeve; 3. the opening positions of the piston ring and the supporting ring are correct, and the horizontal directions are staggered by 180 degrees; the special guide tool for piston installation has enough strength, certain toughness, lubricating performance of the guide surface and higher shape and position precision. The manufacturing process is as follows:
and (3) manufacturing a guide sleeve:
s1, measuring the inner diameter dimension of a cylinder sleeve of a primary cylinder of a tubular primary machine, the outer diameter dimension of the cylinder sleeve, the dimension of the end face of a mounting position of the cylinder sleeve from the end face of a cylinder head, the dimension of a circle where a large cover fastening bolt of the cylinder head is positioned, and the like;
s2, determining that the wall thickness of the guide sleeve is consistent with the thickness of the cylinder sleeve in order to ensure the strength of the guide sleeve, and the length of the guide sleeve is the size from the end face of the mounting position of the cylinder sleeve to the end face of the cylinder head;
s3, in order to ensure the guiding precision of the guiding sleeve, determining that the surface roughness of the working surface (inner cylindrical surface) of the guiding sleeve is Ra1.6, and the coaxiality tolerance of the outer cylindrical surface of the guiding sleeve and the reference (inner cylindrical surface) is 0.04mm.
S4, in order to enable the guide sleeve to have proper surface lubricating performance, PEEK or modified tetrafluoroethylene can be selected as a material, and the material price is high, but compared with the method for ensuring the installation quality and ensuring the stable operation of an expensive compressor, the guide sleeve has extremely high economical efficiency.
After the guide sleeve 2 is installed, the first-stage cylinder head cover bolt is fastened by screwing six flange holes on the second flange block 3 matched with the cylinder head end face through the guide sleeve 2 into the cylinder head end face bolt holes, so that the front end face of the guide sleeve 2 is tightly attached to the cylinder sleeve end face. The same cylindrical surface is formed (the inner diameter of the guide sleeve is equal to the inner diameter of the cylinder sleeve). The end face flange of the guide sleeve is provided with a section of matching spigot, the end face arc section of the first flange block 1 is matched with the end face arc section, and the end face arc section is connected and fastened by two cylinder head covers through bolts. The guiding surface of the first flange block 1 faces to the outer side of the cylinder head and forms the same guiding surface with the guiding surface of the guiding sleeve 2. The purpose is that before the piston enters the guide sleeve 2, the supporting ring and the piston ring are pressed into the ring groove in advance, and the guide surface of the first flange block 1 is limited to be separated from the ring groove, so that the piston smoothly enters the inner hole of the guide surface of the guide sleeve 2.
