Reciprocating type compressor packing cooling system

Abstract

The invention discloses a reciprocating type compressor packing cooling system. The reciprocating type compressor packing cooling system comprises a piston rod (1); a flange (2) is arranged on the piston rod (1); a front packing box (3) and a rear packing box (4) are respectively arranged on the two sides of the flange (2); a packing box assembly (5) is arranged between the flange (5) and the rear packing box (4); the front packing box (3), the flange (2), the packing box assembly (5) and the rear packing box (4) are arranged closely; a cooling circulating channel which is communicated with the front packing box (3), the flange (2), the packing box assembly (5) and the rear packing box (4) is arranged in the front packing box (3), the flange (2), the packing box assembly (5) and the rear packing box (4). The reciprocating type compressor packing cooling system has the advantages of skilful structural design, low cost and reliable use; the cooling flowing area of the packing is greatly increased; the heat exchange efficiency is improved; moreover, the temperature of the packing boxes are reduced; the service life of the packing is prolonged; the sealing property is maintained.

Description

technical field [0001] The invention relates to a reciprocating compressor, in particular to a packing cooling system for a reciprocating compressor. Background technique [0002] At present, in a reciprocating compressor, in order to prevent the gas in the cylinder from leaking along the reciprocating piston rod, a packing is often used for sealing between the cylinder and the piston rod of the reciprocating compressor. However, the packing is affected by the high-temperature gas heat transfer in the cylinder and the frictional heat generated by the reciprocating high-speed movement of the piston rod and the packing, resulting in more heat accumulation of the packing and poor working conditions; in order to improve the working conditions of the packing, it is usually necessary A cooling system is installed in the middle, and coolant is passed through the cooling system to cool and cool the packing, which is used to improve the life of the packing. [0003] If the packing c...

Problems solved by technology

[0005] 1. Adopt single-channel axial flow or single-channel annular flow structure, the cooling system flow is longer, and the lower temperature coolant is not easy to reach each packing area quickly;

[0006] 2. Limited by the installation space, the diameter of the packing device is limited. The existing conventional packing cooling system has a small flow diameter, a small flow area, and a small flow of coolant;

[0007] 3. The high and low temperature areas of the filler cannot be distinguished. For example, some fillers have a high temperature at the front end and some fillers have a high temperature at the rear end. The existing conventional filler cooling system cannot accurately guide the lower temperature coolant to quickly reach the front or rear end of the filler
