Types of Air Compressor Accessories
The air compressor accessories produced by our company mainly include the following types
01
Air Compressor Solenoid Valve
Air Compressor Solenoid Valve is mainly used in diesel screw air compressors to control the flow of fluids (such as air, lubricating oil, coolant, etc.) through electromagnetic force. It can accurately and quickly open or close the corresponding fluid channels according to the signal of the control system, realize the automatic control of the air intake, exhaust, lubrication, and cooling of the air compressor, and ensure the coordinated and orderly operation of various systems of the air compressor.
02
Air Compressor Relay
In diesel screw air compressors, Air Compressor Relay is a crucial component. It acts like a signal "transfer station" and "amplifier." When it receives a relatively weak electrical signal from the control system, it can amplify or convert the signal. After that, these processed signals are used to control the on/off state of the circuits where high-power loads, such as motors and solenoid valves, are located in the air compressor.
03
Air Compressor Intake Valve
Air Compressor Intake Valve plays a key role in diesel screw air compressors. It controls the passage of outside air into the air compressor. The Air Compressor Intake Valve opens at the right time when the air compressor is working to allow sufficient air to enter the compressor cavity smoothly, and closes when air intake is not needed to ensure stable pressure in the compressor cavity and avoid backflow, thereby ensuring that the air can be effectively compressed and subsequently utilized according to the working process of the air compressor.

Functions of Air Compressor Accessories
Air Compressor Solenoid Valve
Air compressor solenoid valves have multiple functions, including:
● Startup & Shutdown Controls: Due to its robust open and shut mechanism, the solenoid valve offers precise startup and shutdown of compressed air flow with minimal pressure fluctuation. It allows or restricts the flow of air by opening or closing the central orifice of the valve.
● Pressure Control: Responding to pressure sensors or controllers, it accurately adjusts the air pressure and mitigates the manifestation of over or under-pressure situations in the pneumatic systems. With a faster response time, the solenoid valve is known for maintaining constant air pressure throughout the system.
● System Safety: The solenoid valve in the air compressor plays a crucial role in safeguarding the compressor units by swiftly cutting off the airflow. Doing so saves the systems from unnecessary pressure-building, safeguarding compressor units from potential damage.
● Power Efficient: A Solenoid valve for compressed air consumes minimal power while controlling the compressed air flow. Its low power consumption with swift performance allows industries to save costs on energy investment while maintaining operational efficiency.
● High Flow Rate: The Solenoid valve is made in such a way that it allows the passage of maximum air with a high flow rate. It aids in offering maximum throughput without lowering the air pressure. It permits industries to achieve maximum efficiency with precise control over compressed air.
Air Compressor Relay
Air compressor relays have multiple functions, including:
● Power control: Its primary function is to switch the power supply to the compressor on or off when needed.
● Protection mechanism: By controlling the power flow, it protects the electrical system from potential damage caused by sudden high current draws when the compressor starts.
● Communication with control system: It receives signals from the thermostat or pressure switch to determine when to activate the compressor.
● High current handling: Due to the high power requirements of the compressor motor, the relay is designed to handle significant electrical currents.
Air Compressor Intake Valve
Air compressor intake valves have multiple functions, including:
● Regulates air intake: The valve opens to allow air into the compressor during the load portion of the cycle, and closes during the unload portion.
● Lubricates the compressor: A small hole in the valve allows oil to flow through to keep the compressor lubricated and cooled.
● Regulates power consumption: The valve's performance affects the compressor's capacity and power consumption.
Installation Precautions for Air Compressor Accessories
● Inspect hoses and fittings: Before attaching any accessory, carefully examine hoses, fittings, and couplings for signs of wear, cracks, or damage. Replace any components that appear compromised.
● Match pressure ratings: Ensure the pressure rating of the accessory is compatible with the air compressor's output pressure.
● Use correct fittings: Only use fittings designed specifically for the air compressor and accessories.
● Tighten connections properly: Hand-tighten all connections, then use a wrench to securely tighten them without over-tightening.
● Apply sealant (if necessary): For threaded connections, use a thread sealant or Teflon tape to ensure a tight seal.
● Check for leaks: Once connected, apply air pressure at a low level and carefully check all connections for leaks.
● Wear appropriate PPE: Always wear safety glasses, hearing protection, and gloves when installing or operating air compressor accessories.
● Follow manufacturer instructions: Refer to the manufacturer's manual for specific installation procedures and safety guidelines for each accessory.
● Grounding: Ensure the compressor and accessories are properly grounded to prevent electrical hazards.
● Proper mounting: Mount the compressor and accessories on a stable, level surface.
● Ventilation: Ensure adequate ventilation in the workspace to prevent overheating.

Our Factory
Jiangxi Gas Compressor Factory began as Ganzhou Machinery Factory after the public-private partnership in 1951. It was renamed Ganzhou Machinery Factory in 1955, Gannan General Machinery Factory in 1958, and Jiangxi Gas Compressor Factory in 1969. Jiangxi Gas Compressor Factory was always at the forefront of the industry in terms of technical strength in the 1970s and 1980s. As a result, the First Ministry of Machinery Industry at that time designated Jiangxi Gas Compressor Factory to conduct research and production of many new models.
