When the general motor in the air separation plant is started, the current that the stator of the motor takes from the power grid is about 5 ~ of the rated current of the motor ~ 7 times. After starting the small motor for one or two seconds, the current decreases rapidly as the rotating speed of the rotor gradually rises; while the large motor needs more than ten seconds, even dozens of seconds before the rotor reaches the stable rotating speed. That is, until the start-up ends, the current drops to the rated value. If the starting current of asynchronous motor is high, what problems will it bring to the use? If this motor starts frequently when it is used, the motor will heat severely due to the influence of starting current, which will affect the normal service life of the motor. In addition, if the starting times of the motor used are not frequent, when its capacity exceeds 30% of the power transformer capacity, due to the large starting current, it will cause the overvoltage dr...

In order to check the installation quality, deformation under low temperature and smooth condition of pipelines, valves and field installed air separation plant in air separation column, needs to be further tighten the flange bolts at low temperature. It is necessary to start freezing before filling the cold insulation box with cold insulation material, which is called naked cooling. During naked cooling, the rectification column, main condensing evaporator and other main equipment shall be cooled to the minimum temperature for 2 hours respectively, and then the whole air separation unit shall be cooled for 3 to 4 hours. The deformation and leakage of each part shall be checked in detail, and the flange bolts shall be tightened again. After defrosting, the flange shall be heated to normal temperature before gas seal test can be conducted.
