Minimum pressure valve connects voltage stabilizing cylinder, and valvular oil return pipe is respectively set with two in the secondary oil return line for being inserted into oil core
Road, the first oil return line connecting screw compressor head, the second oil return line connect oil collection box；
Steps are as follows for test method：
1st step measures capacity Q of the helical-lobe compressor under customer demand pressure at expulsion, weighs the quality m of oil collection box0；
2nd step, the valve for opening the first oil return line close the valve on the second oil return line, open helical-lobe compressor,
Helical-lobe compressor is inflated to voltage stabilizing cylinder；
3rd step, after voltage stabilizing cylinder reaches customer demand pressure at expulsion, adjust the outlet tap of voltage stabilizing cylinder, keep steady
Press cylinder pressure stability；
4th step, operation a period of time, oil core is allowed to be impregnated with completely by lubricating oil, until oil return is steady in secondary oil return line
It is fixed；
5th step, the valve for closing the first oil return line open simultaneously the valve on the second oil return line, and record and start
Moment t0；
6th step, operation a period of time stop compressor, record end moment t1, claim again oil collection box quality m1；
7th step calculates compressed air exhaust oil content according to following formula
8th step adjusts the caliber into gs-oil separator by flow velocity adjusting apparatus, repeats the 1st the-the 7 step of step, passes through ratio
It is vented oil content compared with compressed air, seeks the entrance caliber of best pre-separation effect.
In order to further solve above-mentioned technical problem, this gs-oil separator pre-separation effect test method also has to be changed as follows
Into：
1, gs-oil separator bottom passes through an oil return line connecting screw compressor head.
2, in the 4th step, judge whether return flow stablizes whether oil return is steady in secondary oil return line to determine by visual observation
It is fixed.
3, in the 8th step, height or diameter to the crude separation of gs-oil separator inside every cylinder are adjusted, and seek best pre- point
Gs-oil separator separated structure from effect.
Using the method for the present invention, simply and effectively gs-oil separator pre-separation effect can be tested, sought by test
It asks with the gs-oil separator separated structure of optimal separation effect and the matching relationship of entrance velocity, reduces after-treatment system oil removing
Pressure, can effectively extend the replacement cycle of after-treatment system rapid wear attrition component, reduce maintenance cost, improve compressed air quality etc.
Grade.
Description of the drawings
The present invention will be further described below with reference to the drawings.
Fig. 1 is this test principle figure.
