Embodiment

[0028] Figure 1-3 A preferred embodiment of a synchronous two-stage compressor of the present invention is shown. The synchronous two-stage compressor in this embodiment specifically includes a cylinder block 22, and the cylinder block 22 has a plurality of cylinders arranged in a straight line inside, so The cylinder is provided with a compression chamber, and the compression chamber is provided with a secondary piston 2 sequentially arranged from top to bottom, an inter-stage check valve 4 with a central hole, and a primary piston 1. The primary piston 1 The linkage between the two-stage piston 2 and the synchronous shaft 3 is realized. The middle part of the inter-stage check valve 4 is provided with a central hole for accommodating the synchronous shaft 3. In the compression chamber, the first-stage piston 1 and the inter-stage one-way The first compression chamber 5, the second compression chamber 6 and the third compression chamber are formed between the valves 4, betwe...

Abstract

The invention provides a synchronous two-stage compressor. The synchronous two-stage compressor comprises a cylinder body, a plurality of air cylinders are arranged in the cylinder body, a compression cavity is formed in each air cylinder, a second-stage piston, an interstage one-way valve and a first-stage piston are arranged in each compression cavity, the first-stage pistons and the second-stage pistons are linked through synchronous shafts, and a center hole is formed in the middle of each interstage one-way valve; a first compression chamber and a second compression chamber are arranged in each compression cavity, an air inlet channel and an exhaust channel are arranged on the outer side of the cylinder body, the cross section area of the first compression chambers is larger than that of the second compression chambers, and an air inlet one-way valve communicating with the corresponding first compression chamber is arranged in each air cylinder; and an exhaust one-way valve communicating with the corresponding second compression chamber is arranged in each air cylinder. The problems that the working power of prime power is reduced due to the fact that compressed exhaust of each stage of cylinder in the compressor needs to bear a backpressure load generated by exhaust pressure feedback, and sealing ring assemblies on piston rods are prone to leakage and damage; and leakage of gas in a compression cylinder is increased after the sealing ring assemblies are damaged are solved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a synchronous two-stage compressor. Background technique [0002] At present, most of the existing gas compressors are single-stage compression and multi-stage compression. Most of the cylinders are horizontal parallel symmetrical cylinders. The piston reciprocates to compress the gas in the tank, and the piston rod and the cylinder are sealed by multiple sets of packing seal ring components, which are used to block the compressed gas in the cylinder and control leakage. Multi-stage compression is a After the primary cylinder is compressed, it is cooled and enters the secondary cylinder for compression. The device has the following disadvantages: [0003] 1. The cylinder body is bulky and heavy and takes up a lot of space. [0004] 2. Because the piston rod is in a moving state, it is difficult to completely seal it with the packing seal ring assembly, so that the gas is ea...
