After using the 6D32-285 compressor for more than 30 years, the compressor flaps are damaged frequently, resulting in more system shutdowns and longer parking time, which seriously affects the long-term operation of production and restricts the improvement of economic benefits. In order to change this situation, the factory organized relevant personnel to carry out technical research. According to statistics, analysis and research on the damage of the previous valve, the damage of the valve itself is the main reason for parking. Through investigation, it was found that the bacterial valve of a limited company has reliable performance and corrosion resistance. Its promised service life is more than 180 days, and the price is suitable. Therefore, it is decided to try it on the 6D32-250 compressor. Now introduce the new mushroom valve (referred to as the mushroom valve) and the original commonly used air cushion valve (referred to as the air cushion valve).
The nitrogen and hydrogen compressors start to operate. The cylinder inlets of the east and west sections are connected to the gas main pipe. The process medium is the same, and the inlet pressure and temperature are the same. The operation shows that the pressure in the east and west sections can meet the production needs. However, the average temperature of the eastern section of the exit is 128 °C, the average temperature of the west section of the exit is 153 °C, and the temperature difference between the east section of the compressor and the west section reaches 25 °C. Therefore, the new gas valve reduces power loss and has the characteristics of high strength and high circulation efficiency.
The temperature difference between the eastern section and the west section of the nitrogen-hydrogen compressor reaches 25 °C. Refer to the inlet and outlet temperatures of the east and west sections of other compressors. After considering various factors, calculate by 10 °C. The statistics of the parking caused by the valve problems during the operation of the original compressor show that the original air cushion valve has frequent failures, the shortest running time is 5d, and the average running time is 22.25d. When the equipment was overhauled in October 2001, it was cleaned up. It runs 79d before cleaning, and runs 187d after cleaning. It can be seen that its life and quality are cleared, and the running time is obviously longer than the original air cushion valve.
