TaiFab 是什么意思啊? taifab貌似是一种纤维材料品牌，side channel pump应该是旁路调节泵吧 我猜错啦！说到side channel pump不得不说side channel principle 希望有大虾翻译下面的 side channel principle the side channel principle is also based on the method of dynamic compression (transforming flow energy into pressure energy). the side channel design is suited for applications requiring both, pressure and vacuum. depending upon model size-single stage or two stage-vacuum up to 20 "h2o in suction operation and pressure mode can be obtained. the capacities range from 10 to 650 cfm. non-contact operation means side channel blowers are practically free of wear and maintenance. the pumping medium is not contaminated from carbon dust or oil, as occurs with dry running or oil lubricated rotary vane pumps. the ring-shaped working chamber (1) has a circular cross section (2). one half of this cross section is formed by the impeller (3) with its radial blades (4) on one side, while the other fixed half is formed in the housing (5). the working chamber has an inlet port (6) and an outlet port (7) with the impeller shown in the diagram rotating in an anti-clockwise direction. between the inlet and outlet ports is the rotor (8) filling up the side channel. air is trapped between the impeller pockets of the rotating impeller and is then accelerated centrifugally. the air stream is ducted by the centrifugal force into the side channel blower. the impeller pockets then take it up and the air is then re-directed back into the following pocket, which repeats the process. the air is accelerated and compressed in the impeller several times. the more the blower is throttled, either at the inlet or discharge, the greater the number of impeller re-entries and hence increased compression. one can compare the movement of an air molecule within a side channel with a spring, the pitch of which tighter the more the air is throttled. when you measure the pressure at different points on the ring channel, you find that it rises constantly from inlet (6) to outlet (7). the side channel principle works as a vacuum pump when throttled on the suction side, and as a compressor when throttled on the pressure side.
