    • PURPOSE: A water jet type screw fluid machine is provided to increase lifetime of a shaft sealing device and to accurately notify to an operator by detecting or predicting the shaft sealing device. CONSTITUTION: A water jet type screw fluid machine comprises a casing(2), a screw rotor(4), a water supplying device, a first non-contact seal(16), a second non-contact seal(17), a lip seal(13), and a pressurized connection path. The casing forms a rotor chamber(3). The screw rotor compresses an object gas or converts the expansion force of the object gas into torque. The water supplying device jets water in the inside of the rotor chamber, thereby lubricating the screw rotor. The first non-contact seal, the second non-contact seal, and the lip seal are successively installed from the rotor chamber side between the rotor chamber and a bearing of a rotor shaft of the screw rotor. The pressurized connection path induces the object gas of high pressures in a pressurizing space formed in between the first and second non-contact seals. [Reference numerals] (34) Control device
    • 目的:提供一种喷水式螺杆流体机,以增加轴封装置的使用寿命,并通过检测或预测轴封装置来精确地通知操作人员。 构成:喷水式螺杆流体机械包括壳体(2),螺杆转子(4),供水装置,第一非接触密封件(16),第二非接触密封件(17),唇部 密封件(13)和加压连接路径。 壳体形成转子室(3)。 螺杆转子压缩目标气体或将对象气体的膨胀力转换为扭矩。 供水装置在转子室的内部喷射水,从而润滑螺杆转子。 第一非接触式密封件,第二非接触式密封件和唇形密封件从转子室侧的转子室与螺杆转子的转子轴的轴承依次安装。 加压连接路径在形成在第一和第二非接触式密封件之间的加压空间中引起高压的目标气体。 (附图标记)(34)控制装置
