In recent years, with the wide application of screw air compressors and the increase of market demand, oil-free screw air compressors have become more and more popular in the market. Many customers also ask questions about oil-free screw air compressors.
Introduce the oil-free screw air compressor. Can be divided into several categories: water lubrication, dry and reciprocating.
1. water-lubricated air compressor.
Its dynamic bearing system is completely oil-free because the oil-free air compressor uses a stainless steel rotor. And because water spray can reduce the speed of the equipment, the volumetric efficiency of oil-free air compression is higher.
2. dry air compressor
during the operation of the dry grinding oil-free air compressor, the screw rotor generates gas compression through high-speed expansion, and the screw of the dry grinding oil-free air compressor is sprayed with resin objects to protect the screw from damage in high-speed friction.
3. reciprocating air compressor
miniature reciprocating oil-free air compressor motor single-axis drive, symmetrical distribution crank rocker mechanical structure. The layout of the single-axis double-cylinder structure of the reciprocating oil-free air compressor can make the air flow of the equipment in the rated value range and the speed is twice that of the single-cylinder, thus solving the vibration noise of the single-cylinder compressor very well.
Users can make a choice according to their own production situation. Of course, different industries have different requirements for oil-free air compressors.
Air compressor equipment attribute analysis As a basic equipment in the industrial field, the attribute positioning of air compressor needs to be comprehensively judged in combination with application scenarios and technical characteristics. The specific analysis is as follows: 1. General equipment attribute analysis Cross-industry application Air compressor is widely used
The method of adjusting the pressure of the air compressor mainly depends on the type of air compressor. However, in general, the pressure of the air compressor can be adjusted in the following ways: Adjust the safety valve: The air compressor is usually equipped with a safety valve to control the pressure.
Permanent magnet variable frequency air compressor and power frequency air compressor have their own advantages and disadvantages, which is better depends on the specific application scenarios and needs. The following is a detailed comparison of the two air compressors: 1. energy efficiency and energy saving permanent magnet variable frequency air compressor: using permanent magnet variable frequency motor, can be based on
Air compressor in the use of the process may encounter a variety of hidden dangers, these hidden dangers may affect the normal operation of the equipment, production safety and the quality of compressed air. The following are some common hidden dangers of air compressors: Overload operation: If the air compressor is overloaded for a long time
The slow pumping of the air compressor may be caused by a variety of factors. The following are some possible solutions: Check the air filter: If the air filter is clogged, it will affect the air intake of the air compressor and cause slow pumping. Therefore, it is necessary to regularly clean or replace the air filter.
Analysis of Water Treatment Method for Water Accumulation in Air Compressor Pipeline During the operation of air compressor, water vapor in compressed air is easy to form water accumulation in the pipeline when it is cold and condensed. If it is not treated in time, it may lead to equipment corrosion, gas end failure, product quality decline and other problems. Water from the following
CNC lathes usually need to be equipped with air compressors. Air compressors play a vital role in the operation of CNC lathes, which are mainly reflected in the following aspects: 1. the role of air compressors in CNC lathes to drive pneumatic components: CNC lathes
When discussing the cost of air compressor per cubic meter of air, we have to mention the water-lubricated air compressor produced by Shanghai Granklin Group. With its high efficiency, energy saving, environmental protection and oil-free characteristics, it stands out in the market and provides users with A cost-effective compressed air solution.
Low-pressure air compressor equipment plays an important role in many fields and scenarios. The following are some main fields that require low-pressure air compressor equipment: Medical and pharmaceutical industries: In this field with extremely high requirements for air purity and pressure stability, low-pressure air compressor equipment can
The power of the air compressor is related to its displacement (I. e. air flow), pressure increase and mechanical efficiency. Therefore, the power of the air compressor cannot be determined only according to the displacement (such as 20m & sup3;). However, in general, the power of the air compressor is usually in the product gauge.
