The gas of the oil-free screw compressor does not contact the lubricating oil at all during the compression process. The male rotor drives the female rotor to rotate through the gear. The synchronous gear ensures the rotor gap when transmitting power, so the rotors do not contact each other and leave a certain amount. Gap.
The oil-free screw compressor adopts water-lubricated compression technology, and no lubricating oil is needed in the compression process. Therefore, this compressor is indeed "oil-free", which not only reduces maintenance costs, but also improves the quality of compressed air.
For a 22kW air compressor, the amount of compressed air that can be produced (usually measured in cubic meters per minute or cubic meters per hour) is not directly determined by the single factor of power. In fact, the displacement of the air compressor is also affected by many factors, including but not limited
There are two basic types of screw air compressors: oil-injected and oil-free. Oil-injected (or oil-immersed) screw air compressors use oil to lubricate the screw unit and ensure its smooth operation. The oil also helps cool the compressed air and prevents the equipment from overheating. Pressure
There is water in the air from the air compressor, and replacing the filter element is a possible solution, but whether it is effective depends on the source of the moisture and the root cause of the problem. The following is a detailed analysis of this problem: The role of the filter element: The filter element mainly plays a role in filtering and purifying the air compressor
There is no fixed answer to the question of whether the electric air compressor belongs to large machinery, because it depends on the specific model and specifications. Generally speaking, large electric air compressors can indeed be classified as large machinery. their bodies.
There is still water in the air compressor after using the air source treatment device. There are many possible reasons. The following are some main factors: matching problem of cold dryer: if the processing capacity of the cold dryer equipped with the screw air compressor is less than the exhaust capacity of the air compressor, then the cold dryer may
The difference between air compressor oil-free and oil injection machine is mainly reflected in the following aspects: 1. working principle Oil-free air compressor: No oil is involved in the compression process. It usually uses special high-temperature materials such as Teflon or molybdenum disulfide to solve the compression process.
In the era of industrial manufacturing that pursues high efficiency and environmental protection, oil-free compressed air has become an indispensable key element in many high-end fields. Shanghai Granklin Group, as a leader in the industry, with its innovative water-lubricated screw air compressor products, leading the oil-free
Q: Screw air compressor are frequency conversion? A: No. The water-lubricated oil-free screw air compressor produced by Shanghai Granklin Group has three series: 1. Power frequency air compressor (referring to the use of ordinary motors and ordinary controllers). 2. Frequency conversion
There are some significant differences between the permanent magnet frequency conversion and the power frequency version of the screw air compressor. The following are their main differences: Working principle: Permanent magnet variable frequency air compressor: using permanent magnet synchronous motor, through the frequency converter to control the speed of the motor, so as to achieve air compression
Displacement of air compressor flow related terms: displacement is the total working volume formed in one revolution of the air compressor, in m3 or cm3. Volume flow: also known as displacement or nameplate flow, refers to the air compressor unit time under the required rated exhaust pressure
