Further, the separator unit is equipped with first order filter layer and second level filter layer successively from outside to inside, The first order filter layer and second level filter layer is supported by metal support network and is fixed, and setting double-filtration layer can be by gas Oil gas in body is sufficiently separated out.

Further, the bottom of the gas mixture separator is equipped with long-pending oil slot, convenient for receiving the oil droplet after separation Collection.

Further, the fixing piece is metal coating net, and the gas mixture separator after combination can be made to be integrally formed, Ensure the stability of structure.

Further, the top of the gas mixture separator is equipped with the flange for connection.

The separator unit that the utility model uses may be used standard-sized separator and be assembled, height and straight Diameter can change according to the requirement of the air compressor machine treating capacity of seriation, meanwhile, it can be selected for the air compressor machine of different flow size The usage quantity for increasing or decreasing standard size separator is selected, to increase or reduce first order separation filter material, second level separation filter The area of material has to cope with different compressed air requires and designs the characteristics such as versatile, production is flexible, in gs-oil separator ruler In the case that very little diameter is constant, increases or decreases standard size separator and gas mixture realization is detached twice, reduce clean Oil droplet content in compressed air.

The utility model structure has the following advantages：

1, versatile：The height and diameter of this gas mixture separator are specifically true according to the requirement of air compressor machine treating capacity It is fixed, it is possible to reduce the gs-oil separator usage quantity of serial air compressor machine.

2, flexible design：For air compressor machine newly developed, design scheme can be rapidly completed, match different compressed air requires Requirement.

3, separation is efficient：Gs-oil separator detaches filter material and the second level by the first order and detaches filter material separation, large scale and The oil droplet of small size all can be efficiently separated out, ensure that taking oil mass in the cleaned air of compressor output remains at 3ppm Below.

4, good economy performance：The gs-oil separator quantity that complete series air compressor machine uses can be greatly reduced, reduction is designed and developed into Sheet, the consumption of maintaining inventories expense, production link and the delivery cycle for reducing gs-oil separator, and then reduce exhaust end base of oil injection threaded bolt compression The cost of parts of machine machine.
