Air compressors can be divided into various types according to their working principle, structural characteristics and application needs. Here are some common categories of air compressors: Pistol of piston air compressors: Working principle: Complete the compression process through up and down movement of the piston. Features: Simple structure, stable and reliable, suitable for small and […]

The calculation of the gas volume and pressure of compressed air in the air compressor involves many aspects. The following is a clear and partial summary: 1. Determination of gas volume Traditional method: Add the gas volume (m³/min) of all gas-using equipment. Consider adding a safety, leakage and development coefficient. Test method: Perform a timed […]

There are differences between fixed frequency and non-fixed frequency (converter). There are significant differences in the working principle, operation mode, energy consumption, stability, noise and vibration, cost, and applicable scenarios. 1. Working principle and operation mode Fixed frequency screw unit: Working principle: Gas compression is achieved through the rotational movement of a pair of spiral-shaped […]

The air compressor has water in the air outlet, and replacing the filter element is a feasible solution. The reasons why there is water in the air compressor’s air outlet may include: The moisture content in the air is too high: the moisture in the air will condense into liquid water during the compression process. […]

Oil-free and water-free air compressors mainly achieve lubrication through the following methods: Dry lubrication: Principle: Coat a special layer of solid lubricating materials on the surface of key components inside the compressor, such as polytetrafluoroethylene (PTFE), etc. Features: These solid lubricating materials have excellent high temperature and wear resistance, which can reduce energy consumption and […]

When choosing an air compressor, the scroll air compressor and the screw air compressor have their own advantages and disadvantages. Which one is better depends on the specific application requirements and scenarios. Advantages of vortex air compressor: Simple structure and stable operation: The vortex air compressor has no reciprocating mechanism, few parts, especially few consumable […]

Air compressors belong to the category of general equipment or general machinery in the manufacturing industry, and are one of the indispensable and important equipment in industrial production. Specifically, air compressors are mainly used in the manufacturing industry to provide power sources and drive various pneumatic tools and equipment. For example, in a sheet metal […]

The gas consumption of air compressors in pharmaceutical factories varies depending on various factors such as production scale, process flow, type and quantity of equipment, and a specific value cannot be given. However, some reference information can be provided based on general situation and industry experience. The gas consumption of air compressors used in pharmaceutical […]

The oil content of the oil injected screw air compressor outlet usually requires no more than 3 ppm (i.e. the oil content in compressed air per cubic meter is not more than 3 mg). The following is a detailed explanation of the oil-containing standard for the outlet of the oil injection screw air compressor: 1. […]

The main differences between oil-free screw air compressors and oil-injection screw air compressors are reflected in the following aspects: 1. Working principle and lubrication method Oil-free screw air compressors: Working principle: Use two inter-meshing screws to compress air. The screw is made of high-strength alloy material and is precision-processed to form a closed compression chamber […]
