Composition Of Air Compressor Mar 26, 2020

Composition of air compressor

1: oil circulation system

Before starting, first start the oil pump control system. After the oil pump control system starts, ensure that the lubrication 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: gas circulation system

When the compressor is working, the air is sucked in through the self-cleaning air filter, and the filter is automatically cleaned by the PLC. After the air is automatically adjusted by the inlet guide vanes, the air enters the first stage compression. After the first stage compression, the gas temperature is higher and then enters The intercooler is cooled (inside the water pipe, outside the gas pipe, the water flow of the intercooler is required to be 110m / h), and then enters the secondary compression system to prevent the gas in the system from pouring into the compression chamber (avoid starting with pressure) ) A suspended full-open check valve is installed in the compressor's exhaust pipe. The gas discharged by the compressor pushes the check valve to the exhaust muffler, then enters the first-stage aftercooler, the second-stage aftercooler, and then enters Exhaust main pipe.

3: waterway circulation system

The cooling water enters the intercooler of the air compressor through the pipeline to cool and cool the first-stage compressed exhaust gas, and then enters the aftercooler to cool the exhaust gas. The other cooling water inlet pipe passes through the two sets of heat exchangers on the upper part of the main motor. Cool the motor windings, and cool the oil cooler all the way.

4: Power distribution system

The air compressor is a 2000kW high-voltage motor (10kV) with full voltage start. The control cabinet is indoor AC, metal armored withdrawable switchgear. The switchgear consists of a fixed cabinet and extractable parts, namely the handcart. For the purpose of control, protection and monitoring, it has the function of "five defenses".

5: screen protection system

The central signaling device is divided into two types of accident signals and notice signals. The main task of the accident signal is to be able to send out an acoustic signal in time when the circuit breaker accidentally trips, and make the corresponding circuit breaker light position signal flash. The main task of the notice signal is to issue an acoustic signal instantaneously or delayed when an abnormal phenomenon occurs in the operating equipment, and to make the light word plate display the content of the abnormal phenomenon.

6: DC power system

PZ32 series full-automatic maintenance-free lead-acid battery DC power supply complete set of equipment, consisting of a charging device screen, a DC feed screen and a battery, 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 screen is the "brain" of the air compressor. The values of various on-site sensors are finally summarized into 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 are out of the allowable range, DTC will issue corresponding alarm or automatically stop the air compressor.
