The pressure range of the low-pressure air compressor varies according to the application scenario and equipment design. Maximum pressure and minimum pressure the definition should be combined with technical specifications and actual needs:
low pressure air compressor usually refers exhaust pressure at 0.2-1.0MPa(2-10bar) the model is suitable for scenarios with low requirements for compressed air pressure.
| Industry | pressure demand | equipment selection |
|---|---|---|
| textile/Foam | 0.5-0.8MPa | standard low pressure air compressor |
| food Processing | 0.6-0.8MPa | oil-free low-pressure air compressor (to avoid oil pollution) |
| laboratory | 0.4-0.6MPa | silent low-pressure air compressor + precision pressure regulating valve |
| inflatable toys | 0.2-0.3MPa | customized low-pressure air compressor (need to be equipped with decompression system) |
Summary: The maximum pressure of the low-pressure air compressor is usually not more than 1.2MPa, and the minimum pressure should be determined according to the process requirements (it is recommended to be ≥ 0.4MPa). When selecting the equipment, priority should be given to the matching of the rated pressure of the equipment with the actual application scenario, and the energy efficiency should be optimized through the pressure adjustment device.
Air compressor permanent magnet refers to a motor that uses permanent magnet materials to generate a magnetic field, which is used to drive the rotor of the air compressor to run and achieve the purpose of compressing air. Compared with the traditional AC induction motor, permanent magnet motor has the advantages of high efficiency, miniaturization and energy saving. This empty.
Scroll compressors and screw compressors are two common types of compressors, which are often used in industrial production in the fields of air compression, gas transportation and refrigeration. Performance Comparison of Scroll Compressor and Screw Compressor
The main difference between air compressor power frequency and permanent magnet frequency conversion is reflected in the motor type, operation mode, energy efficiency, noise and maintenance costs. Motor type: permanent magnet variable frequency air compressor adopts permanent magnet synchronous motor, while power frequency air compressor adopts asynchronous motor.
Q: Oil-free air compressor is really oil-free? Answer: Water-lubricated air compressor is really oil-free. Use pure water to lubricate the compressed air to prevent oil from mixing into the compressed air, thereby avoiding pollution to the post-processing equipment. Using Shanghai Granklin Group
The main differences between medical air compressor and industrial air compressor are reflected in the following aspects: structure and material: medical air compressor usually adopts oil-free lubrication technology, all materials do not contain oil, and the material pays more attention to anti-corrosion, anti-oxidation and other characteristics to ensure the air
The air compressor room of ordinary hospitals, especially those that have already used water to lubricate the air compressor, because the combustion risk caused by oil is removed from the root, it is generally not necessary to set up explosion-proof fans, and it is enough to do a good job of ordinary ventilation and heat dissipation. However, if the computer room is in a special environment with flammable and explosive substances, it is necessary to set up explosion-proof fans, and at the same time, a series of safety measures such as gas monitoring and anti-static should be done.
High-purity compressed air is mainly used in the following key process links in semiconductor manufacturing plants, and its application is closely related to the stringent requirements of chip manufacturing for cleanliness and process stability: 1. wafer surface treatment process Wafer cleaning After chemical mechanical polishing (CMP),
The air compressor is indeed used in the semiconductor process, and its role is very important, which is embodied in the following aspects: 1. provide clean compressed air. The semiconductor manufacturing process has extremely high requirements for air cleanliness, and any tiny dust, Particles or oil mist may affect the core
Whether it is an ordinary compressor or a water-lubricated air compressor, it belongs to the category of machinery and equipment in fixed assets, but also fixed assets and general equipment for production. The depreciation period and accounting methods are implemented according to this category.
The oil content of air is usually classified according to the international standard ISO 8573-1, which clearly stipulates the maximum allowable content of oil in compressed air. The following is the classification of air oil content according to the ISO 8573-1 standard: CLASS 0 (or oil-free grade
