1. Oil circulation system: before starting, the oil pump control system should be started first. After the oil pump control system is started, all lubricating parts of the air compressor can be well lubricated. At the same time, the oil pump control system can adjust the internal oil pressure and oil temperature through the built-in temperature control valve to meet the needs of the system.
2. Air circulation system: when the compressor is working, air is sucked through self-cleaning air filter and cleaned automatically by PLC. The air enters the first stage compression after being adjusted by the inlet guide vane automatically. The temperature of the gas after the first stage compression is higher, and then it enters the intercooler for cooling (the water flows in the pipe, the gas goes out of the pipe, and the water flow of the intercooler is required to be 110m / h) Into the secondary compression system, in order to prevent the gas in the system from pouring into the compression cavity (to avoid starting with pressure), a suspended full open check valve is installed in the exhaust pipe of the compressor. The gas discharged from the compressor pushes the check valve open to enter the exhaust muffler, then enters the primary aftercooler, the secondary aftercooler and then enters the main exhaust pipe.
3. Water circulation system: the cooling water enters the intermediate cooler of the air compressor through the pipeline to cool the gas discharged from the first stage compression, and then enters the aftercooler to cool the exhaust gas. The other cooling water inlet pipe cools the motor winding through two groups of heat exchangers on the upper part of the main motor, and another channel cools the oil cooler.
4. Power distribution system: the air compressor is 2000kW high-voltage motor (10kV), which adopts full voltage starting. The control cabinet is indoor AC and metal armored draw out switch equipment. The switch equipment is composed of fixed cabinet and extractable parts, namely handcart, to realize the purpose of control, protection and monitoring, and has the function of "five prevention".
