Abstract

The invention discloses an automatic lubricating oil compensation device with an automatic decompression valve. The device comprises an oil feeding pipe, an oil lens, a compensation tank, the automatic decompression valve, a first oil inlet pipe, a second oil inlet pipe, an oil control valve and an oil storage tank. One end of the oil feeding pipe is connected with the bottom of the compensation tank, two ends of the first oil inlet pipe are connected with the outlet end of the oil control valve and the compensation tank respectively, the automatic decompression valve is arranged at the top of the compensation tank, and two ends of the second oil inlet pipe are fixedly connected with the bottom of the oil storage tank and the inlet end of the oil control valve respectively. Length scales in the vertical direction are further arranged on the oil lens. By means of the automatic lubricating oil compensation device, lubricating oil filling frequency of a compressor is reduced, and labor intensity of device operators is reduced. Meanwhile, the device operators can timely learn the liquid level height of the lubricating oil of a lubricated part, and normal operation of the compressor is facilitated. By means of the automatic decompression valve, operation is simplified, and use stability is improved.

Description

technical field [0001] The invention relates to the field of lubricating oil compensating components for natural gas compressors, in particular to an automatic lubricating oil compensating device provided with an automatic pressure relief valve. Background technique [0002] Natural gas compression generally adopts multi-stage compression, and piston compressors are mostly used in the prior art. During the working process of each stage of piston compressors, the crank main shaft bearing, crank pin and connecting rod big end bearing bush, crosshead pin and connecting rod Small head bushings, crossheads and slideways, compression cylinders, head packing seals, etc. all need lubricating oil for lubrication. It needs to be replenished in time. If the lubrication effect is not good, it will cause damage to the compressor and even cause more serious production accidents. [0003] In the prior art, a lubricating oil injection port is provided outside the natural gas compressor uni...
