Problems solved by technology

But such an air compressor axial sealing ring has a disadvantage. When the piston rod is worn, the lubricating oil in the roller box will leak into the cylinder through the piston rod, so that the exhaust quality of the air compressor cannot meet the requirements, and it increases Air compressor energy consumption

Embodiment Construction

[0015] The present invention is described below in conjunction with accompanying drawing.

[0016] as attached Figure 1-4 The shown air compressor piston rod axial sealing ring of the present invention includes a sealing ring 3, an outer casing 4 and a tension spring 5; the outer casing 4 is arranged on the outer ring of the sealing ring 3; A tension spring 5 is provided between the closing ring 3 and the overcoat 4; a gap 6 is provided on the sealing ring 3 and the overcoat 4; the gap 6 on the sealing ring 3 and the gap 6 on the overcoat 4 are mutually staggered; The sealing ring 3 and the outer jacket 4 are made of polytetrafluoroethylene.

[0017] Due to the application of the above-mentioned technical solution, the present invention has the following advantages compared with the prior art:

[0018] The air compressor piston rod axial sealing ring of the present invention can be automatically adjusted when the piston rod is worn, which increases the sealing effect and pr...

Abstract

The invention discloses an axial seal ring of an air compressor piston rod. The axial seal ring of the air compressor piston rod comprises driving fit rings, outer sleeves and tension springs, wherein the outer sleeves are arranged on the outer rings of the driving fit rings, the tension springs are arranged between each driving fit ring and each outer sleeve, and notches are formed in the driving fit rings and the outer sleeves. The notches in the driving fit rings are staggered with the notches in the outer sleeves. The driving fit rings and the outer sleeves are made of teflon. The axial seal ring of the air compressor piston rod can automatically adjust when the piston rod is abraded, seal effects are increased, the phenomenon that lubricating oil in a roller box can seep in an air cylinder through the piston rod is prevented, oil content in compressed air is reduced, venting quality is improved, use energy consumption of the air compressor is reduced, and energy is saved.

Description

technical field [0001] The invention relates to an axial sealing ring of a piston rod of an air compressor, in particular to an axial sealing ring of a piston rod of an air compressor which can be automatically adjusted when the piston rod of the air compressor is worn, and belongs to the technical field of air compressors. Background technique [0002] The air compressor is the main body of the air source device. It is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy, and is a pressure generating device for compressing air. A general air compressor axial seal ring consists of an upper seal ring 1 and a lower seal ring 2 (such as figure 1 As shown), the upper seal ring 1 is in contact with the housing, and the lower seal ring 2 is in contact with the piston rod, so that there is enough space between the two seal rings to store lubricating oil, and the pressure on the shaft is more uniform along the axial dir...
