Problems solved by technology

Since the compressor under test usually uses a new oil filter element, the test results of the compressed air quality level are often covered up by the new filter element, which cannot fundamentally reflect the oil removal ability of the compressor itself. The ability is poor, which often causes a large oil removal pressure on the oil separation core and the back-end filter, which greatly shortens its service life and increases maintenance costs.

Abstract

The invention relates to a pre-separation effect test method for an oil-gas separator. By the method, pre-separation effects of the oil-gas separator can be simply and effectively tested, the matching relation between an oil-gas separator separation structure with optimal separation effects and inlet velocity is sought by testing, the oil removing pressure of an after-treatment system is reduced, the replacement period of damageable and consumable parts of the after-treatment system can be effectively prolonged, maintenance cost is reduced, and compressed air quality grade is improved.

Description

technical field [0001] The invention relates to a pre-separation effect test method of a screw air compressor oil-gas separator for rail transit, and belongs to the technical field of rail transit vehicle brake systems. Background technique [0002] With the development of product technology in the rail transit industry, in the field of braking systems, owners are increasingly aware of the importance of compressed air quality levels, maintenance costs, and environmental protection. For this reason, owners put forward higher and higher requirements on the air quality level of rail transit compressors and the replacement cycle of related vulnerable and consumable parts. [0003] In the existing test methods, the measurement of the oil content in the compressed air of the screw compressor is usually to test the compressed air at the final outlet of the post-treatment system. Since the compressor under test usually uses a new oil filter element, the test results of the compress...
