The above analysis shows that the dry twin-screw compressor is a type of machine that is sensitive to the temperature and pressure of the suction medium. It is required that these two process parameters cannot have large fluctuations, so it must be done: (1) Strictly control the compressor The temperature of the inlet gas avoids exacerbating the thermal expansion of the rotor due to excessive temperature in the exhaust section. In order to reduce the return loss, the smaller the gap between the parts, the higher the compressor working efficiency is in ensuring normal operation. The cooling effect of the interstage cooler is monitored at any time to eliminate the excessive temperature of the butadiene inlet due to the high temperature of the circulating water or the decrease of the heat transfer effect caused by the sludge deposition. (2) Reduce the temperature of the compressor oil. The compressor rotor is hollow with a lubricant in the middle to reduce the rotor temperature. Lubricating oil has two functions on the compressor: one is to lubricate the bearings of each part and take away the frictional heat; the other is to cool the hollow rotor of the compressor. Therefore, when the compressor discharge temperature is high, in order to ensure the cooling effect, the oil temperature range must be kept at a low limit; or two oil coolers can be put into use in parallel to increase the heat exchange area and obtain a lower oil temperature. To enhance the cooling effect on the rotor. (3) Strictly control the operating conditions, the suction pressure of the compressor is stable, the outlet pressure does not fluctuate greatly, and the precision of the screw movement is ensured, which is also an advantageous measure to ensure the safe operation of the screw compressor. (4) The long-term use of the outlet muffler will cause throttling due to local blockage, causing distortion of the pressure and temperature in the discharge pipe. Therefore, the original interlocking parking temperature is reduced from 100 to 90, and the temperature measurement point is moved closer to the muffler 35m to enable monitoring. The data is more realistic and effectively guarantees the safety of the screw compressor.
