摘要：
Method for controlling a compressor element of a screw compressor, and the said compressor element (1) has a housing (2) with two meshing helical rotors (3-4) in it that are each supported in the housing (2) in the axial direction (X-X') by means of at least one axial bearing (13 and/or 22), and whereby the housing (2) has an inlet side (10) and outlet side (11), characterised in that this method comprises a process A and/or a process B, whereby: - process A comprises a first step of switching on a first magnet (17) during start-up of the compressor element (1), such that this magnet (17) exerts a force on an aforementioned rotor (3) that is directed from the outlet side (11) to the inlet side (10), and of switching off this first magnet (17) during nominal operation of the compressor element (1); and whereby - process B comprises a first step of keeping a second magnet (21) switched off during start-up of the compressor element (1), and switching on this second magnet (21) during nominal operation of the compressor element (1), such that this second magnet (21) exerts a force that is directed from the inlet side (10) to the outlet side (11).
摘要（中）：
1。一种用于控制螺杆式压缩机的压缩机元件的方法，并且所述压缩机元件（1）具有壳体（2），所述壳体具有两个啮合螺旋转子（3-4），所述两个啮合螺旋转子分别在壳体 （2）具有入口侧（10）和出口侧（11），其特征在于，该方法包括通过至少一个轴向轴承（13和/或22） 过程A和/或过程B，其中：过程A包括在压缩机元件（1）启动期间接通第一磁体（17）的第一步骤，使得该磁体（17）施加力 在从出口侧（11）引导到入口侧（10）的上述转子（3）上，并且在压缩机元件（1）的额定操作期间切断该第一磁体（17）。 并且其中 - 过程B包括在压缩机元件（1）启动期间保持第二磁体（21）关闭并且在压缩机元件（1）的额定操作期间接通该第二磁体（21）的第一步骤， ，使得该第二磁体（21）施加从入口侧（10）指向出口侧（11）的力。
