螺杆式 空气压缩机属於容积式压缩机，其活塞采用螺杆的形式； 这是现今使用的zui主要压缩机类型。 螺杆压缩元件的主要部件是凸形转子和凹形转子， 这两个转子相互靠近移动，使它们之间及腔内的体积逐渐减小。 螺杆式的压力比取决於螺杆的长度和 外形以及排气口的形状。 螺杆元件没有装备任何阀门，不存在产生不平衡的机械力。
Screw air compressor belongs to positive displacement compressor, and its piston adopts the form of screw; This is the Zui main type of compressor used today. The main components of screw compression element are convex rotor and concave rotor. The two rotors move close to each other to gradually reduce the volume between them and in the cavity. The pressure ratio of screw type depends on the length and shape of screw and the shape of exhaust port. The screw element is not equipped with any valve and there is no unbalanced mechanical force.
因此可以在 高的轴速下工作，而且可以兼顾大流量和小的外部尺寸 压缩能力： 旋转螺杆式压缩机系列的功率范围为 4 kW 至 250 kW （5 至 535 hp）， 所产生的工作压力为 5 bar 至 13 bar （72 至 188 psi）。 其典型用途是： 食品、饮料、酿造 军事、航天、汽车 工业、电子、制造、石化 医疗、 医院
Therefore, it can work at high shaft speed and take into account large flow and small external dimension compression capacity: the power range of rotary screw compressor series is 4 kW to 250 kW (5 to 535 HP) and the resulting working pressure is 5 bar to 13 bar (72 to 188 psi). Its typical uses are: food, beverage, brewing, military, aerospace, automotive industry, electronics, manufacturing, petrochemical, medical and hospital
