Q: screw air compressor are frequency conversion?
Answer: It is not.
There are three series of water-lubricated oil-free screw air compressors produced by Shanghai Granklin Group:
1, power frequency air compressor (refers to the use of ordinary motor, ordinary controller).
2, variable frequency air compressor (refers to the use of ordinary variable frequency motor, variable frequency controller).
3, permanent magnet variable frequency air compressor (refers to the use of permanent magnet variable frequency motor, variable frequency controller).
Shanghai Granklin Group produces the above three categories of "water-lubricated oil-free air compressors ". If you need oil-free air with high cleanliness, please consult us.
According to the demand for gas, the requirements for energy consumption and the use time, the third permanent magnet variable frequency air compressor is the most energy-saving. It is recommended to choose permanent magnet variable frequency air compressor for long-term use of air compressor, which can save considerable electricity charges every year.
Explosion-proof air compressor is an air compressor specially used in flammable and explosive places. It adopts the explosion-proof technology of the whole machine and has an explosion-proof electric box, so as to avoid the arc, spark and high temperature that may be generated by the fault in the machine, and then ignite the gas and dust in the surrounding environment.
With the widespread use of oil-free air compressors, micro-oil air compressors have gradually entered people's field of vision. Oil-free air compressors, as the name implies, produce compressed air completely free of oil. Micro-oil air compressor, the compressed air produced by it contains oil, but the content is very high.
General air compressor pressure is how much depends on its type, specifications and the use of the environment. The following are some common air compressor pressure ranges: Low pressure air compressor: The working pressure is usually between 0.7 and 1.2 MPa (MPa), that is, 7 to 12 bar. Medium pressure
As an important industrial equipment, air compressor has a wide range of docking industries, covering almost all fields that require power sources or compressed air. The following are some of the main industries of air compressor docking: mechanical processing industry and manufacturing: air compressor in mechanical processing
Screw-type air compressors perform well in many aspects. The following is a detailed analysis of their performance: High reliability: The structure of the screw-type compressor is solid. Although there are many parts, it can be ensured through reasonable design and manufacturing. The reliability of operation is relatively
The reason for the loud noise of the air compressor can be attributed to the following points: Air inlet and outlet noise: When the air compressor is running, the air will produce strong airflow noise through the inlet and outlet. This is due to the high speed flow of the gas stream and the pressure change. Specifically, when the air is fast
The replacement cycle of the air filter (air filter) of the screw air compressor depends on the use environment and working conditions of the equipment. The following are some general suggestions on the replacement cycle of the air filter of the screw air compressor: the running-in period of the new machine: the newly purchased screw air compressor is running for about 500
There is a close relationship between the exhaust pressure and energy consumption of screw air compressor. The following is a detailed analysis of this relationship: 1. basic concept Exhaust pressure: refers to the highest pressure of the air compressor discharge gas, also known as the air compressor working pressure. Common working pressure
In the design of air compressor system, the matching of equipment air consumption and air compressor displacement is the core link to ensure stable production and energy efficiency optimization. The following is a professional analysis from three dimensions: technical principles, configuration principles, and typical scenarios: 1. equipment air consumption
As an important equipment in industrial production, the danger of air compressor is mainly reflected in the following aspects: 1. explosion danger internal failure or unreasonable design: heat will be generated in the process of air compression. If the compressor fails or the design is unreasonable, the heat cannot
