油循环系统：在启动前，首先启动油泵控制系统，油泵控制系统启动后保证空压机各润滑部件润滑良好，同时油泵控制系统可通过内置的温控阀来调节内部油压和油温，以满足系统需要。
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、气路循环系统：压缩机工作时，空气经过自洁式空气过滤器被吸入，通过PLC自动清洗过滤器，空气在经过进口导叶自动调节后进入一级压缩，经一级压缩后的气体温度较高，然后进入中间冷却器进行冷却(水走管内，气走管外，中冷器的水流量要求为110m/h)之后进入二级压缩系统，为避免系统中的气体倒入压缩腔内(避免带压起动)在压缩机的排气管道安装有一只悬挂全启式止回阀，压缩机排出的气体推开止回阀进入排气消声器，然后进入一级后冷器，二级后冷器，再进入排气主管道。
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、水路循环系统：冷却水通过管道进入空压井盖钢模具 U型槽模具 天津水处理设备 检查井钢模具 保定公司注册 u型槽模具 流水槽模具机中间冷却器对一级压缩排出的气体进行冷却降温，再进入后冷器对排气进行冷却，另一路冷却水进水管道经过主电机上部的两组换热器冷却电机绕组，还有一路对油冷却器进行冷却。
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.
