Screw rod compressor and oil separating barrel component thereof

Abstract

The invention provides a screw rod compressor and an oil separating barrel component of the screw rod compressor. The oil separating barrel component comprises an oil separating barrel, an oil separating filter screen and a flow guide component. An end cover is arranged at the end of the oil separating barrel, the oil separating filter screen is arranged in the oil separating barrel, and a separating cavity is formed between the oil separating filter screen and the end cover. The separating cavity is isolated by the flow guide component into an upper portion and a lower portion, and an isolation cavity for containing an exhaust pipe is further arranged in the flow guide component. When the air flow exhausted by the exhaust pipe is away from the flow guide component, the flow guide component is used for giving the centrifugal speed to air flow, and therefore oil and gas are separated, and separated refrigerant oil passes through a clearance between the oil separating barrel and the oil separating filter screen and then flows to enter an oil containing cavity. According to the oil separating barrel component, the phenomenon that the separated refrigerant oil is disturbed by the air flow can be avoided, and the problems that the oil separating effect is poor, and the oil level is unstable can be solved.

Description

technical field [0001] The invention relates to a screw compressor, in particular to a screw compressor which adopts a slide valve to adjust load and an oil separating barrel part thereof. Background technique [0002] Screw compressors usually use slide valves for load regulation. In the screw compressor, the slide valve is a moving part. In order to ensure its stable operation, the slide valve is often arranged under the rotor in the design. However, the arrangement of the lower slide valve often brings a new problem. Since the slide valve is placed downward, the exhaust port located at the exhaust bearing seat has to be located below. The gas discharged from the exhaust pipe must pass through the oil filter to separate the refrigerated oil carried by the gas, and then be discharged from the compressor through the stop valve. Since there is separated refrigerated oil at the bottom of the compressor oil separator barrel, the gas discharged from the exhaust pipe that is t...

AI Technical Summary

Problems solved by technology

Since there is separated refrigerated oil at the bottom of the compressor oil separator barrel, the gas discharged from the exhaust pipe that is too low will disturb the separated refrigerated oil, making the oil separation effect worse, the oil level unstable, and even the compressor Difficulty supplying oil

[0003] In the prior art, the exhaust height is generally increased through the elbow to avoid the exhaust disturbing the oil level. If the elbow and the cavity are integrally formed, the structure of the compressor will become complicated and the manufacture will be more difficult. If it is installed separately Bend pipe, because the bend pipe cannot be effectively fixed, it is easy to cause noise

[0004] In addition, in order to prevent the refrigerated oil from splashing at the bottom of the oil separator, there is also an oil retaining rib installed on the side of the oil separator screen. This oil retaining rib is a cantilever structure, which is easy to cause vibration and noise
