The rotor of screw compressor is burnt out

Liquid air separation plant cold energy utilises air separation equipment, generally large air separation equipment with 2 combined expanders. The price is around 4 million RMB. The expansion air in the air separation plant is no longer required, so for the internal compression process air separation, the inlet air volume of the circulating booster is reduced by about 40% (from 5.A-2A). The energy consumption of the booster is reduced and the investment is reduced. Liquid air separation equipmen...

1.In the process of preparation and implementation of hoisting construction, the safety and quality assurance system must ensure the normal operation,to ensure that the hoisting project meets the requirements of safety and quality. Before hoisting, safety and quality inspection must be carried out, and it must comply with the code forLifting construction of chemical engineering construction (HG20201-2000) and other regulations and specifications. 2.The crane performance shall meet the requirements of hoisting process, and the alarm and hydraulic system must be reliable. 3.Strictly implement the provisions of the technical documents attached to the crane. 4.The hoisting schedule of auxiliary crane should match that of main crane. 5.The hook deflection angle shall not be greater than 3°. 6.It is forbidden to drag the unitdirectly on the ground with crane. 7.Before unithoisting, trial hoisting shall be carried out. The clear hoisting distance and the foundation change at
