AI Technical Summary
The cylinder structure of existing dual-V type air compressors causes the piston to swing violently during high-pressure operation, resulting in severe friction between the piston and cylinder liner, rapid wear of piston rings and cylinder liner, and consequently, air leakage and oil leakage from the compressor crankcase breather.
The high-pressure section cylinder is changed from the traditional stepped design to a single-acting design, and the stepped design is applied to the low-pressure section. Combined with precision component design, including the first and second stage cylinder blocks, intake valve, exhaust valve, first stage cylinder head and valve pushrod, the friction between the piston body and cylinder liner is reduced, and the service life of piston rings and cylinder liners is extended.
It significantly reduces friction and wear between the piston and cylinder liner, lowers the risk of air leakage, improves the compression efficiency and stability of the compressor, reduces oil leakage and environmental pollution, and lowers maintenance costs and downtime.

TECHNICAL FIELD

[0002] In the existing double V type air compressor design, the structure layout of the cylinder mostly adopts the differential cylinder design, and two stages of compression are arranged on one column of cylinders. Although this design has its advantages in technology, it has exposed a series of technical problems in the actual application process.
[0003] Firstly, when the differential cylinder design operates at a high pressure stage, the piston body is prone to large swing under a high pressure environment due to a large pressure difference. Such swing not only aggravates the friction between the piston body and the cylinder sleeve, but also easily leads to rapid wear of the piston ring and the cylinder sleeve. The aggravation of wear not only shortens the service life of the equipment, but also increases the maintenance cost and downtime.
[0004] Secondly, when the piston ring fails due to wear, air leakage will occur. Air leakage not only reduces the gas production of the compressor and affects the performance of the equipment, but also leads to pressure imbalance inside the compressor. In extreme cases, such pressure imbalance can even cause oil to spew out of the breathing port of the crankcase of the compressor, and in severe cases, it can even cause oil to spew out. This not only pollutes the working environment, but also can seriously affect the normal operation of the equipment. INVENTION CONTENTS
