The carbon dioxide compressor refers to a compressor used to pressurize and deliver carbon dioxide gas. Mainly used in urea synthesis equipment. Attention should be paid to the design and use: (1) The critical temperature of carbon dioxide is high, and it can be liquefied at 31.3℃ and 7.14MPa. When used in winter, the inter-stage cooling temperature cannot be too low; (2) When the carbon dioxide is below 60MPa, it is beneficial to the gas (3) Due to the relatively high density of carbon dioxide gas, it is not advisable to use too large average piston speed, otherwise the valve resistance will be large; (4) Carbon dioxide gas contains a small amount of water and is highly corrosive, so the valve, Coolers and buffer tanks are all made of stainless steel.
Features:
①A wide range of applicable pressures. Piston compressors can be designed for low pressure, medium pressure, high pressure and ultra high pressure. At the same speed, when the discharge pressure fluctuates, the displacement of the piston compressor remains basically unchanged.
②The compression efficiency is high. The process of compressing gas by the piston compressor is a closed system, and the compression efficiency is high.
③Strong adaptability, piston compressor has a wide range of displacement, and the influence of gas density on compressor performance is not as significant as that of speed compressor. Piston compressors of the same specification can often be applied to other compressions with a little modification. Gas medium.
