1: oil circulation system of the air compressor
Before starting, start the oil pump control system first. After starting the oil pump control system, ensure that all 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: Gas circuit circulation system of the air compressor
When the compressor works, the air is sucked in through the self-cleaning air filter and the filter is automatically cleaned by PLC. The air enters the primary compression after being automatically adjusted by the inlet guide vane. The gas temperature after the primary compression is high, and then enters the intercooler for cooling (the water flow in the water pipe, outside the gas pipe, and 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 (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 the check valve into the exhaust muffler, then into the primary aftercooler, secondary aftercooler and then into the main exhaust pipe.
3: Waterway circulation system of the air compressor
The cooling water enters the intercooler of the air compressor through the pipe to cool the gas discharged from the primary compression, and then enters the aftercooler to cool the exhaust. 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 the other way cools the oil cooler.
4: Distribution system of the air compressor
The air compressor is a 2000kW high-voltage motor (10kV), which adopts full voltage startup. The control cabinet is an indoor AC and metal armored withdrawable switchgear. The switchgear is composed of fixed cabinet and withdrawable parts, i.e. handcart, to achieve the purpose of control, protection and monitoring, and has the function of "five prevention".
5: Screen protection system of the air compressor
The central signal device is divided into accident signal and advance notice signal. The main task of the accident signal is to send out the sound signal in time and make the corresponding circuit breaker light position signal flash when the circuit breaker trips in an accident. The main task of the advance signal is to send an audio signal instantaneously or delayed when an abnormal phenomenon occurs in the operating equipment, and make the optical plate display the contents of the abnormal phenomenon.
6: DC power supply system of the air compressor
Pz32 series full-automatic maintenance free lead-acid battery DC power supply complete equipment is composed of charging device panel, DC feed panel and battery. It has the functions of automatic current stabilization, automatic voltage stabilization and automatic voltage regulation to provide power for central signal panel and high-voltage control system.
7: DTC control system
The DTC control panel is the "brain" of the air compressor. The values of various field sensors are finally summarized to the DTC control panel, which displays various operating parameters and monitors the operating status of various parts of the air compressor. When some parameters exceed the allowable range, DTC will send corresponding alarm or automatically shut down the air compressor.
