What are the components of the air compressor?

1: Oil circulation system
Before starting, first start the oil pump control system. After the oil pump control system is started, ensure that the lubricating parts of the air compressor are 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, the air is sucked through the self-cleaning air filter, and the filter is automatically cleaned by PLC. The air enters the first stage compression after being automatically adjusted by the inlet guide vane. The temperature of the first stage compressed gas is higher, and then enters After the intercooler is cooled (in the water pipe, outside the gas pipe, the water flow requirement of the intercooler is 110m/h), it enters the secondary compression system to prevent the gas in the system from being poured into the compression chamber (avoid starting under pressure) ) A suspended full-open check valve is installed in the exhaust pipe of the compressor. The gas discharged from the compressor pushes open the check valve and enters the exhaust muffler, then enters the primary aftercooler, the secondary aftercooler, and then enters Main exhaust pipe.

3: Water circulation system
The cooling water enters the air compressor intercooler through the pipeline to cool down the gas discharged from the first stage compression, and then enters the aftercooler to cool the exhaust gas, and the other cooling water inlet pipeline passes through the two sets of heat exchangers on the upper part of the main motor To cool the motor windings, there is a way to cool the oil cooler.

4: Power distribution system
The air compressor is a 2000kW high voltage motor (10kV) with full voltage start. The control cabinet is an indoor AC, metal armored withdrawable switchgear. The switchgear is composed of a fixed cabinet and a withdrawable part, namely a handcart. For the purpose of control, protection and monitoring, it has the function of "five preventions".

5: Screen protection system
The central signal device is divided into two types: accident signal and forecast signal. The main task of the accident signal is to send out the sound signal in time when the circuit breaker accidentally trips, and make the corresponding circuit breaker light position signal flash. The main task of the pre-announcement signal is to send out an acoustic signal instantaneously or delayed when an abnormal phenomenon occurs in the operating equipment, and to make the light sign display the content of the abnormal phenomenon.

6: DC power supply system
The PZ32 series of automatic maintenance-free lead-acid battery DC power supply complete equipment is composed of a charging device screen, a DC feed screen and a battery. It has functions such as automatic current stabilization, automatic voltage stabilization, and automatic voltage regulation. It is a central signal screen and high-voltage control system. Provide power.

7: DTC control system
The DTC control panel is the "brain" of the air compressor. The values ​​of various field sensors are finally summarized on the DTC control panel. Various operating parameters are displayed on the DTC control panel, and the operating status of each part of the air compressor is monitored. When these parameters exceed the allowable range, DTC will issue a corresponding alarm or automatically stop the air compressor.
