The friction force in the clutch works just like the blocks in the frication section of brake, except that the spring presses on the clutch plate instead of weight pressing the block into the ground.

离合器的摩擦力和制动器的摩擦力起一样的作用，不同的是压在地面上的重压力变成了离合器中弹簧压在离合器盘上的压力。

The amount of force the clutch can hold depends on the friction between the clutch plate and they flywheel, and how much force the spring puts on the pressure plate.

离合器能传递的力的大小取决于离合器盘和飞轮之间的摩擦系数，以及弹簧对压盘的压紧力的大小。

The damage factors are mostly poor equipment, low or high pressure bag, the bag from the top blowing in the porous plate or dust cover, eventually friction damage.

破损因素是大都为设备不良，袋口小或压差过高，使滤袋脱离多孔板顶在喷吹管或除尘器盖板上，终究磨擦破损。

What's more, a machine-made surface produces the wrong kind of friction: to do its job precisely, the plate's surface needs minute scorings, of only a few microns each, where machine oil can reside.
