usage method:
This product relies on the hand wheel to drive the valve rod to adjust the nut guide sinus to rise and fall, so as to make the adjustment plate adjust the clear position. Features of the product: the nut part does not contact pulverized coal, so that the nut and screw rod will not be stuck. Therefore, it should be flexible and long service life.
Precautions and maintenance:
1. Clean the channel during installation and no dirt is allowed to adhere. 2. The adjusting plate is a vulnerable part and can be replaced at any time.
