Lubricating device in piston compressor transmission mechanism

Abstract

The invention discloses a lubricating device in a piston compressor transmission mechanism. The lubricating device consists of a lubricating oil tank, a coarse filter, a main hydraulic pump, an auxiliary hydraulic pump, an oil cooler, a fine oil filter, pressure adjusting valves and a pipeline, wherein the main hydraulic pump and the auxiliary hydraulic pump are arranged in parallel in the lubricating device of the compressor transmission mechanism; the two pressure adjusting valves are arranged at the outlet of the hydraulic pump and the outlet of the fine oil filter respectively. The lubricating device in the piston compressor transmission mechanism disclosed by the invention has the advantages of compact structure, safe and reliable configuration, function of alarming and halting in case of abnormal pressure, running stability and reliability, superior lubricating effect and higher economic benefit.

Description

technical field [0001] The invention relates to a compressor, in particular to a lubricating device in a transmission mechanism of a piston compressor, and belongs to the technical field of compressors. Background technique [0002] Large-scale piston compressors are key equipment in many industrial enterprises, and their operating effects directly affect the economic benefits of enterprises. Lubrication is an important factor for the normal operation of large-scale piston compressors. At present, the lubrication system of the transmission mechanism of large piston compressors in many enterprise installations is mainly composed of lubricating oil tank, main hydraulic pump, auxiliary hydraulic pump, oil cooler, oil filter, valves and pipelines. The pressure is used for circulating lubrication, and the main hydraulic pump is directly driven by the outrigger shaft at one end of the crankshaft, which ensures that as long as the compressor is running, there must be lubricating oi...

AI Technical Summary

Problems solved by technology

[0003] At present, there are many problems in the lubrication system of the transmission mechanism of large piston compressors, mainly including: 1) The failure rate of the main hydraulic pump of the shaft head is high, the gear hydraulic pump of the main hydraulic pump is unstable, the operation noise is loud, and the seal is not good; 2) The main hydraulic pump is directly driven by the crankshaft of the compressor. If the main hydraulic pump fails, the compressor must be stopped for maintenance, which seriously affects production; 3) The oil filter has poor filtering effect and is prone to oil leakage; 4) There is no pressure regulation in the oil circuit valve, the entire oil circuit is prone to large oil pressure fluctuations and low oil pressure

The above problems have caused considerable economic losses to the enterprise
