Air compressor product introduction permanent magnet water lubrication air compressor manufacturers

Air compressor is not only the basic product of modern industrial development, but also a kind of all-pneumatic equipment. Shanghai granklin Group Co., Ltd. is a production-oriented entity enterprise integrating production, development and sales. it is a professional manufacturer of water-lubricated oil-free air compressors in China.

Air compressor is divided:

1. Speed type;

2. Volumetric type; Volumetric type is divided into rotary type and reciprocating type; rotary type:(1) rotor type;(2) screw type;(3) sliding type. Reciprocating:(1) Piston type;(2) Membrane type.

Speed type: It relies on the action of the gas in the high-speed rotating impeller to obtain a larger kinetic energy, and then the speed is reduced sharply in the diffuser to convert the kinetic energy of the gas into potential energy, thereby increasing the gas pressure. Speed type mainly has two basic types of centrifugal and axial flow.

Volumetric type: The purpose of increasing the gas pressure is achieved by directly compressing the gas to reduce the gas volume. The volumetric type is divided into two types: rotary type and reciprocating type according to the characteristics of the cylinder piston. Function: gas production, refrigeration and separation, driving power, synthesis and polymerization, gas transportation, etc. Rotary type: The piston rotates, the piston is also called turning dry, the number of rotors is different, and the shape of the cylinder is different. Rotary type includes rotor type, screw type, sliding vane type, etc. including piston type air compressor.

Reciprocating: The piston reciprocates and the cylinder is cylindrical. Reciprocating includes piston type and membrane type, of which piston type is the most widely used type.

With the rapid development of industry and the improvement of people's living standards, the requirements of the society for the required products have been greatly improved. At the same time, the improvement of the precision of pneumatic components has promoted the higher and higher requirements for the oil and water content of compressed gas. In the past, the new products of oil-free air compressors have greatly restricted their wide use due to quality problems.

With the development of society, air compressors (I. e. air compressors) are generally used in all walks of life involving the national economy, and air compressors are general mechanical equipment.

With the improvement of the quality of the oil-free air compressor, its quality has been fundamentally improved, which can fully meet the needs of modern industrial production. The superiority of the oil-free air compressor in the use process is reflected, as follows:

in the past two years, permanent magnet variable frequency air compressor has become synonymous with energy-saving pioneers in the air compressor industry. Even some air compressor manufacturers use "air compressor without money" as an advertising slogan to attract users' attention.

Of course, the permanent magnet variable frequency air compressor motor energy saving, relatively speaking, with the same control method is certainly higher than the traditional asynchronous motor. The key point of energy saving is that 80% of the air compressors are in variable load state, and frequency conversion speed regulation is used to automatically meet the needs of users according to the amount of gas consumption, thus reducing the loss of useless work.

however, there are still 20% of the occasions with full pressure and full load. In this case, the use of frequency conversion to control asynchronous motors consumes more energy than direct starting, because the frequency converter itself controls the frequency level by switching IGBT, and it itself has a rated power of 2 ~ 3% and needs to be lost.

Therefore, in this case, the energy-saving effect of frequency conversion control will not be obvious even if permanent magnet motors are used. However, the current national standard assessment of the energy efficiency level of air compressors is still based on the specific power at full pressure and full load. Only high-precision screw heads with high-efficiency motors and reasonable layout design of air compressors can achieve the specific power of level 1 energy efficiency. Therefore, many screw machines using frequency conversion control are difficult to achieve level 1 energy efficiency level.
