Site for cleaning the rotor of large double-suction centrifugal pumps

Can such a shiny surface rust?

Have you seen such spray painting work? Two more people are needed to hold it.

Centrifugal pump or centrifugal compressor?

High-pressure water cleaning, followed by inspection and anti-corrosion treatment.

High-pressure water cleaning, followed by inspection; no anti-corrosion treatment is required.

Answer: The three-stage refrigeration compressor is under maintenance; the impeller is being cleaned with high-pressure water. @Fish in the desert @LongTengJiU Tian @Mighty Ultraman @XiaoXin_zvyyp @kimok06 @We11We11 @Keneng88 For more internal photos of compressor maintenance, please see: Ethylene Maintenance--Internal Photos of Compressors https://bbs.hcbbs.com/thread-3262781-1-1.html

Clean the compressor rotor with high-pressure water.

Is the maintenance of three-stage refrigeration compressors used in ethylene plants?

The Ternary refrigeration compressor unit, an important piece of equipment for Qilu Petrochemical’s 720,000-ton ethylene upgrade project, has entered the intensive phase of equipment calibration and process piping work following its successful overall lifting. Experts say this is the world’s first ternary refrigeration compressor used in ethylene production. Xu Xingnian, a senior engineer specializing in ethylene in China, explained that this compressor is the world’s first ternary refrigeration compressor to be used in ethylene production. It incorporates the latest technology from the American company ABB LUMMUS, was designed and manufactured by the Japanese company Mitsubishi Electric, has a power output of 17,000 kilowatts, and its total investment amounts to over 5 million US dollars. This compressor is capable of providing the cooling capacity and temperature ranges required for ethylene, propylene, and methane, serving as a replacement for the separate refrigeration compressors used for these three substances. It boasts numerous advantages such as high cooling capacity, a wide range of temperature options, low energy consumption, high level of automation, and compact size, making it suitable to meet the production needs after the expansion of the 720,000-ton ethylene plant.

Yes, it’s the triple-refrigeration compressor used in ethylene plants, made by Mitsubishi in Japan. During the pandemic, the Japanese workers couldn’t come, but the major maintenance work still had to be carried out as planned, so Chinese workers did the job themselves.
