转子是滑片式压缩机的主要零件。常见的喷油滑片式压缩机转子通常具有8条纵向凹槽,槽窄而且深,槽侧面要求的光洁度和尺寸精度却比较高。为了减少滑片与转子间的机械摩擦与磨损,以利滑片沿径向自由滑动,槽面应进行表面硬化和磨削。国外有的样本上已将此作为广告宣传。据了解国内基本上还是采用铣削直接加工到规定尺寸的。衢州煤矿机械厂为了适应煤矿井下需要,对转子槽进行了高频淬火与磨削取得成功,提高了槽的尺寸精度与光洁度,硬度达HRc 45以上,大大提高了转子与滑片的使用寿命,受到用户欢迎。
The rotor is the main part of the vane compressor. Common injector vane-type compressor rotors typically have eight longitudinal grooves that are narrow and deep, requiring higher finish and dimensional accuracy on the sides of the groove. In order to reduce the mechanical friction and wear between the vane and the rotor, in order to facilitate the vane sliding freely in the radial direction, the groove surface should be hardened and ground. Some foreign countries have already advertised this as an example. It is understood that the basic domestic or milling directly processed to the specified size. Quzhou Coal Mine Machinery Plant in order to meet the needs of underground coal mines, the rotor groove of high-frequency quenching and grinding success and improve the groove size accuracy and finish, the hardness of HRc 45 above, greatly improving the rotor and slide service life, Welcome by the user.
