Problems solved by technology

However, due to the reduction of the refrigerant charge of the low back pressure compressor, the amount of lubricating oil sealed will also be reduced. The traditional lubrication method will cause the problem of insufficient oil supply between the bearing and the crankshaft, which will lead to the failure of the bearing. wear and tear

Abstract

The invention discloses a low-back-pressure horizontal compressor and a refrigerating system. The compressor comprises a shell and a compressing mechanism, wherein the shell is provided with an air suction pipe and an air discharging pipe, and a low-pressure oil pool is arranged at the bottom of the shell; the compressing mechanism comprises two air cylinder, two fitted bearings, two cover plates, a crankshaft and a rolling bearing, the cover plates are respectively arranged at the sides, facing to each other, of the two air cylinders, the two fitted bearings are connected through a retainer to define a closed air discharging cavity, the crankshaft is matched with the two fitted bearings, the rolling bearing is arranged between at least one fitted bearing and the crankshaft, the part, which is provided with the rolling bearing, of the fitted bearing is matched with the crankshaft in a sliding manner, a central hole is formed in the crankshaft, a plurality of radial holes are formed in the crankshaft and are communicated with the central hole, the central hole is communicated with the low-pressure oil pool through an oil supplying pipe, and each fitted bearing and at least one radial hole are correspondingly arranged. The compressor provided by the invention is beneficial to increasing oil supplying amount and alleviating the abrasion of the fitted bearings.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a low back pressure horizontal compressor and a refrigeration system. Background technique [0002] Low back pressure compressors, such as low back pressure compressors using hydrocarbon refrigerants, have suction pressure inside the shell, which makes low back pressure compressors have low solubility of refrigerant and refrigerating machine oil, less refrigerant charge, and low back pressure in the shell. Low body temperature and other advantages, low back pressure compressors have a wide range of applications. However, due to the reduction of the refrigerant charge of the low back pressure compressor, the amount of lubricating oil sealed will also be reduced. The traditional lubrication method will cause the problem of insufficient oil supply between the bearing and the crankshaft, which will lead to the failure of the bearing. wear and tear.
