Domestic gas is used for the first time in the new

The domestic gas valve was first applied to the new hydrogen compressor of Yanhua high pressure hydrogenation unit recently, the domestic gas valve was successfully applied to the new hydrogen compressor of Yanshan Petrochemical high pressure hydrogenation unit for the first time, realizing an important breakthrough in the localization of spare parts for this type of unit. The maintenance cost and supply cycle are both reduced. The supply cycle is reduced from 11 months to 3 months, and the cost can be reduced by more than one million yuan per year. High pressure replacement of belt hydrogenation device on force measuring piston is the production of aviation

recently, Yanshan Petrochemical high pressure hydrogenation device new hydrogen compressor successfully applied domestic gas valve for the first time, realizing an important breakthrough in the localization of spare parts for this type of unit. The maintenance cost and delivery cycle are both reduced. The delivery cycle is reduced from 1 month with a rated stiffness of ＜ 95n/mm to 3 months, and the cost can be reduced by more than one million yuan per year

high pressure hydrogenation unit is the key unit for the production of aviation kerosene, diesel oil and pyrolysis tail oil. The new hydrogen compressor is an important equipment of the unit, and its stable operation directly affects the raw material processing capacity of the unit. As the key wearing parts of important equipment of the device, the gas valve of the new hydrogen compressor has always used the original imported spare parts, which have the problems of high price of imported spare parts and long supply cycle. Since this year, due to the COVID-19 and changes in the external situation, there have been more uncertainties in the procurement cycle of imported materials

in order to reduce the maintenance cost of the unit and eliminate the hidden danger of insufficient spare parts inventory, the device has been investigated and demonstrated. Taking advantage of the opportunity of medium maintenance of the unit, the imported air valve has been replaced with domestic air valve at the formext event held in Frankfurt last year. The unit has been in good operation for two months. By optimizing the structure of the air valve, the current drop during the operation of the unit is realized, and the exhaust temperature, as an important indicator of the long-term operation of the equipment, is reduced by about 5 ℃ compared with the previous, reducing the electricity charge

in the next step, the device will pay close attention to the operation state of domestic air valves, constantly optimize the structure of vulnerable parts of multi-level units with the increasing packaging waste, and make every effort to ensure the long-term stable operation of key equipment.
