Problems solved by technology

[0004] 1. The elastic part of the piston rod is stretched by manual tightening of six tool bolts, which results in low work efficiency;
[0005] 2. Frequent operation and use will easily damage the screws and threads, and need to be reconfigured;
[0006] 3. Rubber plugs and rubber rings need to be replaced frequently due to service life issues, which affects work efficiency;
[0007] 4. The elongation of the piston rod cannot be directly measured by measuring instruments. At present, it is only judged by the actual experience of technicians, and there is a large error in it

Abstract

The invention discloses a connecting structure and connecting method of a piston rod crosshead. The connecting structure comprises pressure-bearing rings, sealing rubber rings, a first connector, a pressure body, a crosshead body, pressure-bearing gaskets, adjusting gaskets, flanges, fasteners and a piston rod. The piston rod is sequentially sleeved with the flanges, the pressure-bearing gaskets, the pressure-bearing rings, the sealing rubber rings and the pressure body. The first connector is arranged on an internal passageway of the pressure body, and the internal passageway is communicated with the sealing rubber rings. The outer side of the pressure body is sleeved with the crosshead body. The connecting method comprises the steps that 1, the pressure body, the first connector, the sealing rubber rings, the pressure-bearing rings, the pressure-bearing gaskets and the flanges are arranged on the piston rod, and screwed down. The connecting structure and connecting method can be applied to the technical field of compressor equipment. According to the connecting structure and connecting method, many defects existing in the prior art can be effectively overcome, the overall work efficiency of maintenance and running can be achieved, and it can be effectively guaranteed that a compressor runs normally.

Description

technical field [0001] The invention relates to the technical field of compressor equipment, in particular to a connecting structure and a connecting method of a crosshead of a piston rod. Background technique [0002] The connection method between the piston rod and the crosshead of the compressor prepared by Weifang Shengjian Gas Compressor Factory (see figure 2 ), is a connection method often used in the technical field of compressors at present. The 7MY50 type 7-row six-stage compressor produced by it has 1 set in Hunan Yihua Chemical Co., Ltd., and 5 sets in Chongqing Yihua Chemical Co., Ltd. [0003] During the actual use, our technicians found the following defects in the above connection method: [0004] 1. The elastic part of the piston rod is stretched by manual tightening of six tool bolts, which results in low work efficiency; [0005] 2. Frequent operation and use will easily damage the screws and threads, and need to be reconfigured; [0006] 3. Rubber plug...
