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.
