| Abstract: | The trouble of 300000 m3/h of outlet pressure transmitter and inlet differential pressure transmitter of centrifugal air compressor due to environmental temperature exceeding the limit results in unloading of air compressor. Improving the installation position of site pressure transmitter of air compressor and decreasing the impact by thermal radiation of the air compressor body on the transmitter makes the environmental operating temperature meet the requirement of limited environmental temperature, decrease the trouble ratio of air compressor＇ s site transmitter, improves the reliability of transmitter and ensures safe run of the air compressor. Here, the improvement of transmitter installation position and the effects are described. |
