液化气泵是用于输送催化和气分装置液化气的设备。多年来我们一直采用填料和普通机械密封来密封液化气，但效果不理想，不仅影响生产装置的平稳操作，造成液化气产品质量不合格，而且液化气泄漏成为很大的事故隐患。 为提高装置平稳运行程度，控制产品质量，消除事故隐患，经探 Liquefied petroleum gas pump is used to transport catalytic gas and liquefied gas plant equipment. Over the years we have been using packing and general mechanical seals to seal the liquefied gas, but the effect is not satisfactory, not only affect the smooth operation of the production plant, resulting in liquefied gas product quality unqualified, and liquefied gas leakage as a great accident risk. To improve the smooth operation of the device, control the quality of products, eliminate hidden dangers of accidents, the probe
