. Overview
 image002.jpgThere  is an upper and lower grease feeding mouth on type VSG-KR dual line  distributor. When piston of distributor works forward and adversely, grease is  discharged from the upper and lower feeding mouth once respectively. The  two-in-one grease discharge structured is designed at the corresponding upper  and lower grease feeding mouth. In order to change the grease discharge from an  odd number of outlets, it is only needed to adjust the direction of guide  bushing. The working condition of distributor can also be observed directly  from the movement of indicating rod. Besides, the grease feeding volume at each  grease outlet can be adjusted conveniently within the specified range by  adjusting the screws.
