Problems solved by technology

At present, the scheme adopted by the compressor has the following disadvantages. First, the sealing cavity is small, and the effect of gravity separation and inner wall impact separation is not good; Concentration on the inner wall of the oil separator barrel, the concentration will cause the flow velocity of this part of the airflow to be very high, and the consequence of the high flow velocity is that the effect of the oil filter 1' is poor

Embodiment Construction

[0024] Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0025] Such as figure 2 As shown, according to the embodiment of the present invention, the oil component barrel includes a barrel body 10 and an oil component assembly. The barrel body 10 has a containing cavity; the oil component assembly is arranged in the containing cavity and divides the containing cavity into a first cavity 11 and a second cavity. The volume of the first chamber 11 is less than or equal to the volume of the second chamber 12, the oil component includes an oil filter 21 and a return barrel 22, the opening 221 of the return barrel 22 faces the second chamber 12.

[0026] By arranging the return barrel 22 in the barrel body 10 of the oil separation barrel, the opening 221 of the return barrel 22 faces the second chamber 12, so that the airflow can reduce concentration in the second chamber 12, and is fully compatible wit...

Abstract

An air / oil separator, comprising: a separator body (10), having an accommodating cavity; and an air / oil separation assembly, provided in the accommodating cavity and dividing the accommodating cavity into a first cavity (11) and a second cavity (12), the volume of the first cavity (11) being smaller than or equal to the volume of the second cavity (12); the air / oil separation assembly comprises an air / oil separator filter (21) and a backflow container (22), an opening (221) of the backflow container (22) facing towards the second cavity (12). Further disclosed are a screw compressor and an air conditioning unit having said air / oil separator. Said air / oil separator can improve the air / oil separation efficiency of the compressor.

Description

Technical field [0001] The invention relates to the field of air conditioning equipment, in particular to an oil separator barrel, a screw compressor and an air conditioning unit. Background technique [0002] At present, the built-in oil and gas separation of the screw compressor adopts the separation structure of the oil separation filter. Usually, the structure we use is as follows figure 1 . The compressor exhausts to the sealed cavity 3'formed by the oil separator 1'and the oil separator barrel, and then discharges through the oil separator 1'. The efficiency of oil and gas separation is related to the following factors. One is the flow rate through the oil filter 1'. Generally, the lower the flow rate, the higher the oil separation efficiency; the second is the air flow stroke, the longer the stroke, the better the effect of oil and gas separation due to gravity; the third is the collision with the inner wall of the air flow channel , The larger the area of ​​the inner w...
