(1) phosphating purposes. In order to prevent axial leakage vortex wall. Moving plate in translation when pushed by the intermediate pressure to the back of the moving plate fixing side (high pressure chamber structure), or under the influence of the back pressure chamber pressure so that the movable plate is pushed fixing side (low-pressure chamber structure) larger friction. If the brake disc, fixed disk or moving and stationary plates are manganese phosphate (phosphate coating is generally 3 ~ 12μm), Pistons, since phosphate film has kept oil effect, moving, after phosphate treatment can make the initial fixing adaptability, Taiwan Pistons, will not cause undue wear on the start-up performance is also advantageous. Qingdao Xingchang air compressor group sales in Germany Burg compressor to determine how to evaluate the merits of screw compressor? Actually very simple, specific power was to evaluate the merits of screw compressors most objective and fair evaluation judgment method, the unit is kw / (? / Min). It is characterized by the production of one cubic meter of compressed air required for each configuration of motor power. Specific power input is divided into specific power and specific power output. Power input ratio is the ratio of the total of the whole compressor input power and displacement, namely the machine input power / displacement, used to evaluate the entire screw compressor design and manufacturing standards.
