The air filter is the core component of the air intake system of an air compressor. It is mainly used to filter dust, particles, moisture and other impurities in the air that enters the compressor, preventing pollutants from entering the internal parts of the compressor (such as rotors, cylinders, valves and other key components), thereby ensuring the quality of the compressed air, reducing equipment wear and extending its service life. It is the first line of defense of the compressor's "respiratory system", together with the oil filter and oil separation core, they are called the "three filters" of the compressor, jointly maintaining the efficient and stable operation of the equipment.

The air compressor sensor is the core of the "intelligent" operation of the equipment. By accurately sensing parameters such as pressure, temperature, and flow rate, it enables the transformation from "passive maintenance" to "active prevention". Choosing the appropriate sensor and performing proper maintenance not only extends the lifespan of the air compressor but also reduces energy consumption and shortens downtime due to failures, providing stable and reliable compressed air support for industrial production.

I.Main Components Included in the Set。 Air filter Filters out dust and impurities in the air to prevent them from entering the compressor. It is recommended to replace every 4000 hours to avoid blockage that leads to a decrease in air volume and increased energy consumption. Oil filter Filters impurities in the lubricating oil to protect key components such as bearings and gears. Blockage will cause an increase in oil pressure, triggering a protective shutdown. Oil-gas separator Separates the lubricating oil from the compressed air to ensure that the exhaust contains an acceptable amount of oil (typically ≤ 3ppm). Failure will result in increased fuel consumption, oil in the exhaust, and contamination of the after-treatment equipment. Lubricating oil Synthetic lubricants (such as the SynthOil series from Atlas Copco) provide lubrication, cooling and sealing functions. They need to be replaced every 4,000 hours. Old lubricants will reduce cooling efficiency and increase the risk of carbon deposits. Sealing kit Includes O-rings, gaskets, etc., to prevent leakage of lubricating oil and compressed air. Old sealing parts may cause a decrease in pressure or oil leakage. Other accessories Some packages may include belts (belt drive type), sensors, hoses, etc. II. Advantages of the Maintenance Package One-stop purchase: A single package covers all the replacement needs of key components, avoiding the omission of accessories. Original factory matching: Atlas Copco original accessories ensure perfect compatibility with the equipment, extending the service life. Cost-effectiveness: The package price is usually more favorable than purchasing accessories separately. Professional guidance: A detailed maintenance manual is included, guiding users on how to replace the accessories correctly.

Troubleshooting process Check the power supply: Use a multimeter to check if the power is normal and the voltage is stable. Check the coil: Measure the resistance of the coil to determine if it has burned out. Check the mechanical part of the valve: Remove the valve, check for any foreign objects blocking it and whether the spring is damaged. Check the control system: If it is an automatic drainage system, check if the timer or sensor is working properly. Pressure test: Test the opening and closing functions of the valve under system pressure.

Working Principle Torque Transmission: The torque output by the motor is transmitted through the outer teeth of the coupling, and then via the inner teeth of the intermediate sleeve to the compressor shaft, achieving power transmission. Flexible Compensation: Axial Offset: The axial clearance between the inner and outer teeth allows for a small amount of axial displacement of the two shafts (typically ±0.5 to ±3mm). Radial Offset: The top of the outer teeth is made into a spherical shape (with the center of the sphere on the axis), allowing for a certain angular deviation between the two shafts (typically ≤1°). Angular Offset: Through the sliding and rolling of the tooth surfaces, the angular errors between the two shafts are compensated. Buffering and Vibration Reduction: The lubricating oil fills between the teeth and can absorb some vibration and impact loads, reducing equipment noise.

Pressure sensor Working principle: It achieves pressure monitoring by measuring the pressure difference and converting it into an electrical signal. Main functions: It can monitor the inlet and outlet pressures of the air compressor as well as the pressure of the storage tank in real time, thereby preventing the system from operating under overpressure conditions and effectively ensuring system safety. Application scenarios: It is widely used in pressure control, discharge regulation, and safety protection, etc. Common types: Including strain type, piezoresistive type, etc.
