Electric portable screw air compressors are widely used in mining, hydropower, urban construction, shipbuilding and other industries. With the advantages of portable screw models, they are more consistent with lightweight, miniaturization of the development trend of screw compressors. New type electric portable screw air compressors have greater breakthroughs in terms of system and configuration than the traditional ones. They have achieved high efficiency, high stability and low energy consumption. It is more easy to operate and more convenient to maintain.

It is understood that this equipment is the key equipment for the 200,000-ton/year synthetic ammonia plant in Sichuan Meishan Jinxiang Chemical Co., Ltd. It has a diameter of 2.4 meters, a length of 22.72 meters and a weight of 55 tons. It combines three units of No. 1 ammonia cooling, No. 2 ammonia cooling and cold exchanger, which saves investment, saves space, and saves water and energy.
According to reports, the structure of the device is complex, with many tube plates, and the concentricity, parallelism and verticality are all very high. The parallelism between the center line of the tube plate and the axis of the equipment and the deviation of the perpendicularity between the end face of the tube plate and the axis of the equipment are required. ≤ 1 mm, not easy to control. In addition, the device has five tube plates with a total length of 15.31 meters, and each tube plate has 267 holes. The concentricity and parallelism of tube tubes and tube plates must be accurate to ≤ 1 mm, which is very difficult to manufacture. The tight fit of the pipe and the pipe hole not only requires high processing precision, but also the smoothness of more than 200 pipes is required to reach the brightness of the stainless steel, and the design and manufacturing have a very high degree of difficulty. As a result, the equipment has not been domesticated for a long time.
The first five-tube plate combination ammonia cooler was successfully developed
The first five-tube-plate combination ammonia cooler designed and developed by China itself was recently installed and shipped by Sichuan Bluestar Machinery Co., Ltd. This indicates that the long-term dependence on imports of the equipment has been broken, and has filled the domestic gap.
