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 system needs.
2. Air circulation system
When the compressor is working, the air is inhaled through the self-cleaning air filter, and the filter is automatically cleaned by the PLC. The air enters the primary compression after being automatically adjusted by the inlet guide vanes. The intercooler is cooled (water goes inside the pipe, gas goes outside the pipe, the water flow of the intercooler is required to be 110m/h) and then enters the secondary compression system, in order to prevent the gas in the system from pouring into the compression chamber (to avoid starting with pressure ) A hanging 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 first-level aftercooler, the second-level 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 after-cooler to cool the exhaust gas. 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 also a way to cool the oil cooler.
4. Power distribution system
The air compressor is a 2000kW high-voltage motor (10kV) with full voltage startup, and the control cabinet is an indoor AC, metal armored withdrawable switchgear. For the purpose of control, protection and monitoring, it has the function of "five defenses".
5. Screen protection system
The central signal device is divided into two types: accident signal and pre-announcement signal. The main task of the accident signal is to send out an audio signal in time when the circuit breaker trips in an accident, and make the corresponding circuit breaker light position signal flash. The main task of the pre-announcement signal is to send out an audio signal instantaneously or delayed when an abnormal phenomenon occurs in the operating equipment, and make the light plate display the content of the abnormal phenomenon.
6. DC power system
PZ32 series automatic maintenance-free lead-acid battery DC power supply complete set of equipment, composed of charging device screen, DC feeding screen and battery, with automatic current regulation, automatic voltage regulation, automatic voltage regulation and other functions, for the central signal screen and high-voltage control system Provide power.
7. DTC control system
The DTC control screen is the "brain" of the air compressor. The values of various on-site sensors are finally aggregated to the DTC control screen. Various operating parameters are displayed on the DTC control screen, 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.
