Description

Horizontal rotor compressor

Technical Field

The utility model relates to the technical field of compressors, in particular to a horizontal rotor compressor.

Background

The traditional horizontal rotor compressor cannot directly absorb oil due to the fact that the crankshaft does not extend into refrigerating machine oil, and the oil absorption mode of the traditional horizontal rotor compressor is completed by matching an oil absorption cover with an oil absorption pipe. The concrete mode is, oil suction pipe inserts in the refrigerator oil in oil suction cover top and lower cylinder cap interference fit.

In the prior art, the oil absorption cover belongs to sheet metal parts, and the precision is relatively poor, and is easy to seal with a lower cylinder cover and causes air leakage, so that the oil absorption effect is influenced. Meanwhile, copper pipes are generally used for the oil suction pipe, and the cost is high. The oil suction pipe and the oil suction cover are generally brazed, and welding slag is easy to remain in a brazing mode, so that the compressor is blocked.
