螺杆式压缩机因“泄漏三角形”、啮合间隙、齿顶间隙和端面间隙等造成气体泄漏,其他啮合间隙引起压缩过程中的横向泄漏,即齿间容积内压缩气体直接向吸气侧的泄漏。啮合间隙的泄漏面积由接触线长度和相应间隙值确定。 The screw compressor causes gas leakage due to “leakage triangle”, meshing clearance, tip clearance and end clearance, and other meshing gaps cause lateral leakage during compression, ie leakage of compressed gas directly to the suction side within the interdental volume. The leakage area of ​​the engagement gap is determined by the contact line length and the corresponding clearance value.
