同正负环室结合处泄漏有关。无法用旋紧螺栓的方法消除泄漏，于是拆下节流装置更换密封垫片，然后发现孔板变形。同天气有关。孔板流流量计节流装置本来无泄漏现象，由于天气暴冷，西北风劲吹，引起正负环室结合处泄漏。同节流装置处绝热保温不佳有关。保温良好的节流装置未出现泄漏现象。将上述相关线索联系起来可对孔板变形原因作出推理分析。节流装置设计计算时，孔板外径与环室配合处的间隙留得足够大是假定孔板和环室温度相同，但实际上不可能相同，孔板被环室包围着，而且有高温流体为其提供热量，所以温度高，得到充分膨胀。

原因水质差含颗粒。由于水质差，含有小颗粒及介质中盐酸盐含量高，形成磨料磨损机封的平面或拉伤表面产生沟槽、环沟等现象。处理办法：改进水压或介质，更换机封。原因缺水运行造成干磨损坏。此现象多见于底阀式安装形式进口处负压，进水管有空气，泵腔内有空气，泵开机后，机封的磨擦高速运转时产生高温，无法得到冷却，检查机封，弹簧张力正常，摩擦面烧焦发黑，橡胶变硬开裂。处理办法：排尽管道及泵腔内空气，更换机械密封。

一般来说，罗茨蒸汽压缩风机的转速在98～145r/min，普通离心蒸汽压缩风机的转速在6～9r/min，而单级高压离心风机的高转速可达3r/min。当然，对于罗茨风机来说，其劣势也很明显，其单级体积流量过小、效率低、保养周期短(一般2h/次)是其先天缺陷;同时罗茨风机噪声频谱较宽，且以63-8HZ的低中频噪音为主要成份，在运行中的噪声高达1分贝以上，对人员健康伤害较大。

一般系统设计为压缩机停机一定时间后四通阀才换向，此时高低压趋于平衡，换向到中间位置便停止，即四通阀换向不到位，主滑阀停在中间位置，下次启动时，由于中间流量作用造成流量不足；压缩机启动时流量不足。四通阀换向不良原因四通阀线圈断路、短路或电压不符合线圈性能要求，造成先导阀的阀芯不能动作；由于外部原因，先导阀部变形，造成阀芯不能动作；先导阀毛细管变形或堵塞，造流量不足，形成不了换向所需的压力差；主阀体变形，活塞部被卡死而不能动作；冷冻油变质或系统内进入杂物，四通阀活塞卡死；四通阀焊接时，温度过高，内部零件发生热变形而不能动作；制冷系统冷媒泄漏，冷媒循环量不足，达不到换向所需的压力；压缩机温度过高，由于制冷剂泄漏等原因压缩机得不到很好的冷却，排气温度过高导致四通阀内部零件变形卡死或换向不灵。
