BFA/BFB Relubrication Oil Distributor 定量脱压式分配器

• 0.1ml/0.2ml/0.3ml/0.4ml/0.5ml
• Lubricant delivered from the oil injector starts to drive through the umbrella valve in the BFA distributor.
• When the umbrella valve closes the oil outlet hole, oil pressure forces oil storage block to overcome spring force and lower down, and the oil cavity starts to store oil.
• When BFA oil storage block arrives at the top of the oil cavity, storing oil by BFA is completed.
• When the oil pump stops supplying oil, the decompression valve is automatically opened to make lubricant in the main oil pipe to return through the decompression valve.

The system pressure is lowered, the umbrella valve reciprocates and closes the inlet oil, and the BFA oil storage block compresses the lubricant in the oil cavity to the the oil outlet port.

• 从注油机输送出的润滑油，经BFA分配器中的伞形阀门开始往上推动。
• 当伞形阀门把出油孔封闭后，油压迫使储油块克服弹簧力开始下降，使油腔开始储油。
• 当BFA储油块被顶至油腔顶点时，BFA储油完毕。
• 当油泵停止供油时，其卸压阀自动开启，使主油管内润滑油通过卸压阀回油。此时系统压力下降，同时伞形阀回复封闭进口油，而BFA储油块在弹簧力的作用下开始把油腔内的润滑油往出油口压出。
