Ambient temperature ℃
Use mechanical oil number
5.6.2 Check the operation stability, reliability, impact and vibration during operation. After operation, check that all connecting parts and fasteners should not be loose. 5.7 Oil leakage test
When the feeder is running at no load, wipe the joints clean. If oil marks appear on the static joint surface within 5 minutes, it is oil seepage; if oil drops appear on the dynamic joint surface within 5 minutes, it is oil leakage.
5.8 Noise test of feeder without load
When the feeder is running without load, place the sound level meter on the horizontal plane of the worm center and 1m away from the edge of the feeder.
