As the compressor speed increases, the inter-stage pressure gradually rises, but the high-pressure outlet pressure is zero, accompanied by a buzzing sound. After preliminary analysis, it is considered that the high-pressure cylinder separator is damaged, the high-pressure cylinder is dismantled, and the final stage separator is deformed, and the outlet is blocked. At that time, due to the lack of spare parts, only the mechanical repair was carried out, and the final stage partition that was deformed along the ring was cut. When the synthetic device was overhauled, the block was taken out and replaced with new fittings, but before the device was overhauled, new The accessories were damaged again. Since there were no ready-made accessories, the partition had to be replaced and it has been used ever since. The diffuser is slightly deformed or blocked by the flow passage. During the repair, it is found that there is carbon black and other impurities in the high-pressure cylinder flow passage. After the separator is removed, it is washed with washing oil, and the pressure between the rear sections is obviously decreased. After the side plate itself has a defective device disassembled, from the appearance, one edge of the side plate of the side plate is completely detached, and the whole side plate is completely offset to the outlet side, and the outlet flow path is blocked. From the current situation of the site, it is shown that the side plate is subjected to a force from the inside of the compressor to the outlet. High magnification was observed at the fracture, and the graphite was in the form of a sheet, and the graphite grade was evaluated to be 5 grades. The high-magnification structure is pearlite + flake graphite, and no other original cracks and defects are found in the structure, and the surface has slight corrosion. After macroscopic and microscopic inspection and analysis, it is believed that the failure of the plate is mainly due to the large pressure difference between the two sides in the work and the concentration of stress at the step. The damaged parts will be replaced with new ones. After the start of operation, 102-J runs smoothly, and all the indicators of the high and low pressure cylinders are normal. In order to prevent the damage from happening again, take the following precautions: change the 102-J big auxiliary line valve, outlet valve and one-to-one valve to electric valve, and the main and auxiliary line valves and the outlet valve perform the logic relationship of opening and closing. To ensure the quality of accessories such as diffusers. The operation and operation rules of the compressor unit shall be formulated. The operators shall operate in strict accordance with the operating procedures during operation to avoid the surge phenomenon of the unit as much as possible.
