No pressure in the cylinder before starting the air compressor of small air separation unit

No pressure in the cylinder before starting the air compressor of small air separation unit

Author: DEAR AST

According to the starting characteristics of the motor towing the air compressor, when the air compressor is started, its starting current is several times the current in operation. Too much starting current can have a negative impact on the machine itself, the transformer and the transmission line, so we should try to shorten the starting time and the starting current. However, if pressure exists in the cylinder before the air compressor starts, the starting torque will become larger and the starting current of the motor will be larger than no-load starting, so that it is easy to damage the air compressor or cause accidents on the power grid.

 

Dear Air Separation employs dozens of experts and technicians in machine and vessel equipment manufacturing and inspection to ensure the reliability of equipment manufacturing. We are currently setting up a joint research and exchange mechanism with domestic universities in the areas of intelligent manufacturing, intelligent operation and maintenance, engineering structural science, nano-sensing field and materials science, truly becoming a technology development institution combining academics and production in the small air separation unit and large air separation plant industry.

The plant operation cycle between two large heating is related to many factors. From an operational point of view, this mainly depends on when the air passage of the main heat exchanger is blocked. The main reason for the blockage is that the moisture and carbon dioxide content in the air entering the unit exceeds the standard, which accumulates and freezes in the main heat exchanger until it is blocked. The abnormal operation of molecular sieve purification system will shorten the operation cycle of the unit. It is mainly caused by the following reasons: 1. The molecular sieve adsorption bed is short circuited. In the process of operation, due to the unstable gas velocity control or switching, the pressure difference between the two tanks is too large, which will affect the bed layer, make the molecular sieve bed uneven and make the bed layer short circuit. In serious cases, the dust screen of the adsorber will break and the molecular sieve powder will enter the heat exchanger c
