Sign is：The procedure inspection further includes size detection, carries out size detection after surface treatment, after heat treatment in progress
Sight glass inspection, airtight detection and size detection, the endoscopy are detected valve opening using endoscope 100%, probe
Diameter phi 3mm, 90 ° of field angle, 300,000 pixels, front end superbright LED illumination, 5 grades of illumination is adjustable, and discovery does not remove clean burr
It carries out removing flash removed by hand again, the airtight detection includes being segmented air-leakage test and plane to high-pressure oil duct and cavity is airtight
Detection, detection air pressure are 6bar, and leakage is less than 7cc/min, detection time 30S.
5. the processing method that a kind of intelligence electricity according to claim 1 drives gear box hydraulic control system valve body, special
Sign is：The cleanliness testing comprises the following steps：
1）Prepare, the valve body of test and the instrument of requirement;
2）Sampling, first in mass ratio 1：1 configuration alcoholic solution, then with pressure watering can flush valve body wall, take rinse solution;
3）Drying filtering is weighed, and filter paper is taken to be dried to 50 degree in thermostatic drying chamber first, filter paper precision is 20 μm, diameter phi
55mm, the filter paper for further taking out drying is put into during precise electronic claims, quality is reset, then filter paper is placed on sand core filter device,
Upper hopper, the upper clip of folder are pressed, then rinse solution is poured into funnel, opens sliding vane rotary vacuum pump, then removes funnel taking-up filter paper, baking
It does to 50 degree and takes out filter paper cooling, finally filter paper is placed again into during precise electronic claims, records numerical value;
4）Measurement will be put into biomicroscope and lower whole proper focal length, then by computer software gathered data, will collect first
The largest particles object record numerical value, maximum license generates particle diameter and is less than 100 μm, and total precipitation is less than 3mg.
