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，然后进入一级后冷盖土网 防寒布 麻绳 油麻绳 麻刀 沥青麻绳 静压造型线 自动浇注机 铸铁拍门 钢制拍门 玻璃钢拍门器，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
