1. Overview of HGT800-20 air compressor
HGT800-20 air compressor is a high-performance screw air compressor with a large exhaust volume and pressure range, suitable for a variety of industrial application scenarios.
2. Working principle
The working principle of a screw air compressor usually includes four main processes:
Intake process: inhale outside air through the intake valve.
Sealing and conveying process: air is conveyed in the sealed cavity formed by the screw and the casing.
Compression and oil injection process (for oil-injected screw air compressor): During the compression process, lubricating oil is sprayed in to cool and lubricate the screw and help seal.
Exhaust process: compressed air is discharged through the exhaust valve and enters the air storage tank or directly supplied to the point of use (for example, to meet the working gas demand of the down-the-hole drilling rig)

4. Application scenario
Due to its large exhaust volume and pressure stability, the HGT800-20 air compressor may be widely used in the following fields:
Industrial manufacturing: such as production lines in foundry, steel, automobile, textile, food, pharmaceutical and other industries, providing power and compressed air.
Construction engineering: used for spraying, cleaning, lifting, grinding, drilling and other operations at the construction site, as well as HVAC systems and automatic control.
Aerospace: aircraft maintenance, testing and R&D work, as well as signal and data transmission during the development of spacecraft and satellites.
5. Work Cases
Case Background: Due to the needs of the Guatemalan customer's border protection slope project, our company's down-the-hole drilling rig and air compressor were purchased.
Air compressor workflow:
Startup and loading: After receiving the start signal, the air compressor starts to run, and the screw rotates to inhale and compress the air. When the pressure in the air tank is lower than the set value, the air compressor automatically loads and increases the exhaust volume.
Stable operation: In the stable operation stage, the air compressor automatically adjusts the exhaust volume according to the pressure changes in the air tank to maintain stable pressure. At the same time, the lubricating oil system continues to work to ensure the lubrication and cooling of the screw and bearings.
Unloading and shutdown: When the gas consumption of the production line decreases or the pressure in the gas tank reaches the upper limit, the air compressor automatically unloads, reduces the exhaust volume and enters the standby state. If there is no need for gas for a long time, it will automatically shut down to save energy.
6.Energy-saving transformation case
In order to further improve energy efficiency and reduce operating costs, our company has carried out energy-saving transformation on the HGT800-20 air compressor. Specific measures include:
Install the inverter: The inverter is used to control the speed of the air compressor motor to achieve on-demand air supply and reduce energy consumption during no-load and unloading.
Optimize the cooling system: Improve the cooling system to improve heat dissipation efficiency and reduce the operating temperature of the air compressor, thereby reducing the increase in energy consumption and failure rate caused by overheating.
Regular maintenance: Strengthen the daily maintenance and maintenance of the air compressor to ensure that all components are in good condition and reduce downtime and energy loss caused by failures.
