    • PURPOSE: A water injection type hydraulic screw machine is provided to prevent damage to a contactless seal or a rotor shaft by moving a seal ring in a radial direction when the seal ring of the contactless seal contacts the rotor shaft. CONSTITUTION: A water injection type hydraulic screw machine comprises a first contactless seal(16), a second contactless seal(17), a lip seal(18), a compressing communication path(24), and opening communication paths(25,26). The first contactless seal, the second contactless seal, and the lip seal are installed between a rotor seal and the rotor shaft bearing of a screw rotor. The compressing communication path leads high-pressure gas to a compression space formed between the first contactless seal and the second contactless seal. The opening communication path opens an opening space formed between the second contactless seal and the lip seal to outside.
    • 目的:提供一种注水式液压螺杆机,用于通过在非接触式密封件的密封环接触转子轴时径向移动密封环来防止非接触式密封件或转子轴的损坏。 构成:注水式液压螺杆机包括第一非接触式密封件(16),第二非接触密封件(17),唇形密封件(18),压缩连通路径(24)和开口连通路径(25,26) 。 第一非接触密封件,第二非接触式密封件和唇形密封件安装在转子密封件和螺杆转子的转子轴承之间。 压缩连通路径将高压气体引导到形成在第一非接触式密封件和第二非接触式密封件之间的压缩空间。 开口连通路径将形成在第二非接触式密封件和唇形密封件之间的开口空间打开到外部。

    • Improved water-injected screw compressor element which mainly consists of a housing (2) on the one hand, confining a rotor chamber (5) with an inlet (6) on one far end and an outlet (7) on the other far end and in which two co-operating rotors (3,4) are provided which are bearing-mounted in the housing (2) with their shaft (16,20) by means of water-lubricated bearings (17,18,21,22), characterised in that for every rotor are provided two pistons, a first piston (37,38) and a second piston (17, 21) respectively, which can be each axially shifted in a guide, whereby each of these pistons (17,21,37,38) makes contact with the rotor (3,4) concerned with one side or is part of it, and makes contact with a pressure chamber (41,42,43,44) with an opposite side, in order to partly or almost entirely compensate for axial force components exerted by the compressed gasses on the rotors.
