Guangzhou Petrochemical's domestic parts solve the problem of imported instruments

"The jet fuel jet colloid analyzer is not working properly, and three tanks are waiting for the analysis data to
leave the factory .
" Recently, Wei Qionghua, a technician from the comprehensive analysis area of ​​the Guangzhou Petrochemical Inspection Center, got the news and rushed to the scene as soon as possible

The colloid content of jet fuel injection is one of the important indicators of jet fuel delivery inspection
.
In order not to affect the normal delivery of jet fuel, Wei Qionghua immediately checked the analytical instruments

After consulting the manufacturer, the pump is equipped with a one-way valve to prevent steam backflow.
Domestic accessories cannot meet the requirements.
Imported accessories cost about 15,000 yuan, and the delivery cycle is as long as 6 months
.

"Equipment supply is limited in time, but we can't wait for a moment of production, and we must not affect the analysis of
jet fuel delivery due to instrument failure .
" The inspection center has established a technical research team, and Zheng Jincheng, an engineer in the production equipment room, is a member of the research team

Imported equipment has a certain technical blockade.
Zheng Jincheng has figured out the flow of the entire gas circuit through careful study of the technical data
.
When inspecting the actual pipeline, he found that two independent check valves have been installed on the outlet pipeline of the water pump.

Through repeated demonstrations, the research team unanimously approved his suggestions
.
Zheng Jincheng spent more than 200 yuan to buy a domestic pump with similar technical specifications, and optimized the original pipeline of the instrument to solve the problem of mismatch between the new pump and the original steam pipe

After the optimization and transformation, as the temperature of the instrument reaches the set value, the steam starts to continuously output normally, and the jet fuel jet colloidal analyzer resumes normal operation

In addition, the technicians of the inspection center used their brains and innovated work, replacing the imported automatic decompression distillation apparatus with domestic vacuum pumps, and upgrading imported gas chromatographs with domestic equipment to promote the localization of spare parts in the center
