1: oil circulation system
To begin, it is important to start the oil pump control system. By doing so, the air compressor's lubricating parts can be effectively lubricated. Simultaneously, the built-in temperature control valve within the oil pump control system allows for adjustments in the system's internal oil pressure and temperature, ensuring that the system's requirements are met.
2: air circulation system
When the air compressor is in operation, it draws in air through its self-cleaning air filter, which then passes through the PLC automatic cleaning filter. Next, the air enters the first level of compression after automatic adjustment by the inlet guide vane. As a result of this initial compression, the temperature of the gas rises. To counter this, the air then moves into an intercooler, which cools it down using a water tube and gas outside the pipe. The intercooler requires a water flow of 110m/h.
Once cool, the gas is ready to enter the secondary compression system. However, the gas in the system must be prevented from pouring into the compression chamber due to pressure issues. To resolve this, a suspension full-start check valve is installed in the exhaust pipe of the compressor. This valve allows the gas to exit the compressor and enter the exhaust muffler before moving into the primary rear cooler and secondary rear cooler. Finally, the gas enters the exhaust main pipe, having completed the compression process.
3: water circulation system
The intercooler of the air compressor receives the cooling water via a pipe, which helps in cooling down the gas that is discharged from the primary compression. Afterward, this cooling water flows into the rear cooler to effectively cool the exhaust gas. Additionally, there is another inlet pipe specifically designed for cooling purposes. This pipe passes through the two sets of heat exchangers located at the upper part of the main motor. Its primary function is to provide cooling to the motor winding. Furthermore, this cooling water also serves the purpose of cooling the oil cooler. Hence, it plays a crucial role in maintaining the optimal temperature and performance of various components in the compressor system.
4: Power distribution system
The control cabinet for the indoor AC is equipped with a 2000kW high voltage motor (10kV) air compressor. This air compressor utilizes a full pressure start mechanism, ensuring efficient operation. The switchgear, which is made up of a fixed cabinet and extractable parts, plays a vital role in controlling, protecting, and monitoring the system. It consists of two parts: the fixed cabinet and the extractable parts, which function together to achieve the intended purpose. Additionally, the switchgear is designed with a metal armored extraction type, ensuring durability and safety. It also possesses the essential "five prevention" features to enhance its reliability.
5: Screen protection system
There are two types of divisions in the central signal device: accident signal and warning signal. The accident signal is responsible for timely sending out sound signals and flashing the corresponding circuit breaker light position signal. On the other hand, the warning signal is tasked with instantly or with a delay sending out sound signals when abnormal occurrences happen in the operation equipment. Furthermore, it ensures that the optical plate displays the content of the abnormal phenomenon. To reiterate, the accident signal focuses on sound signals and flashing lights, while the warning signal deals with sound alerts and visual displays for abnormal phenomena.
6: DC power supply system
The PZ32 series of equipment is an automatic and maintenance-free DC power supply that utilizes lead-acid batteries to provide centralized power to a signal panel and high voltage control system. The equipment boasts automatic current and voltage regulation features, ensuring stable and reliable power at all times. The complete equipment comprises a charging device panel, DC feed panel, and battery, making it a reliable source of energy for critical systems.
7:DTC control system
The heart of the air compressor lies in its DTC control panel. This vital component is responsible for processing and summarizing the data captured by the various field sensors. As such, it displays the operating parameters and oversees the running condition of each part of the air compressor.
Moreover, the DTC control panel constantly keeps a watchful eye on the values of the various parameters and alerts the operator through the corresponding alarm or automatic shutdown mechanism if any exceed the permitted limit. Therefore, the DTC is an indispensable component that immensely contributes to the longevity and safe operation of the air compressor.
