螺杆式空气压缩机
Screw air compressor
螺杆式空气压缩机由螺杆机头、电动机、油气分离桶、冷却系统、空气调节系统、润滑系统、安全阀及控制系统等组成。整机装在1个箱体内，自成一体，直接放在平整的水泥地面上即可，无需用地脚螺栓固定在基础上。螺杆机头是1种双轴容积式回转型压缩机头。1对高精密度主(阳)、副(阴)转子水平且平行地装于机壳内部，主(阳)转子有5个齿，而副（阴）转子有6个齿。主转子直径大，副转子直径小。齿形成螺旋状，两者相互啮合。主副转子家庄电动伸缩门 保定桌椅  保定水处理设备 河北机械加工 北京电动门  保定养老院  保定防水两端分别由轴承支承定位。工作时电动机通过连轴器(或皮带)直接带主转子，由于2转子相互啮合，主转子直接带动副转子一同旋转。
Screw air compressor is composed of screw head, motor, oil-gas separation barrel, cooling system, air conditioning system, lubrication system, safety valve and control system. The whole machine is installed in a box and is self-contained. It can be directly placed on the flat cement ground without fixing it on the foundation with anchor bolts. Screw head is a double shaft volumetric rotary compressor head. A pair of high-precision main (male) and auxiliary (female) rotors are installed horizontally and parallel inside the casing. The main (male) rotor has 5 teeth and the auxiliary (female) rotor has 6 teeth. The diameter of the main rotor is large and the diameter of the auxiliary rotor is small. The teeth form a spiral shape and they mesh with each other. Both ends of the main and auxiliary rotors are respectively supported and positioned by bearings. During operation, the motor directly takes the main rotor through the coupling (or belt). Since the two rotors mesh with each other, the main rotor directly drives the auxiliary rotor to rotate together.
