Q: Oil-free screw air compressor and oil injection screw air compressor which is good?
Answer: The air quality is better than the oil-free screw air compressor.
If you do not add pre-conditions, from the price, displacement of course is to choose the oil-injected screw air compressor, but why now many companies prefer to purchase oil-free screw air compressor is a reason.
the benefits of oil free screw air compressor:
1. High gas cleanliness;
2. Energy saving and environmental protection;
3, air compressor maintenance is more simple;
4, more applicable scenarios, medical, electronics, chemical, semiconductor, etc. The higher the scientific and technological content of the industry, the higher the quality requirements of compressed air;
There is a certain relationship between the pressure and the volume of the air compressor. Generally speaking, the higher the pressure of the air compressor, the volume of gas output may be reduced accordingly. This is because, during the compression process, as the gas is compressed, the distance between its molecules decreases, thus making the same
In modern industrial production, the purity of oil-free compressed air has become the focus of attention in many industries. As a leader in the field of air compression, the water-lubricated screw air compressor produced by Shanghai Granklin Group has won the market for its excellent performance and ultimate purity.
The range of air supply pressure for factory air sources varies according to application scenarios and equipment requirements, but the following standards are usually followed: 1. conventional air supply pressure range Pneumatic system: air compressor output pressure: generally 0.6-0.8MPa(6-8kg), and some high-efficiency equipment can reach 1.0MPa.
Definition of displacement: Displacement refers to the amount of air that an air compressor can compress and discharge per unit time. It is an important indicator for measuring the performance of an air compressor.
The air pressure setting of the plant air compressor depends on the specific use needs and equipment specifications. Generally speaking, the pressure range of air compressors commonly used in factories is between 0.6 and 1.0 MPa (MPa). This pressure range can meet most industrial applications
To deal with the water and oil in the air compressor gas, the following measures can be taken: Treat the moisture in the gas Install a gas-water separator: Install a gas-water separator at the outlet of the air compressor, which can effectively separate the moisture in the compressed air. Regularly replace the cooler: ensure cold
There is indeed a relationship between the flow rate and the pressure of the compressor output, which is mainly reflected in the following aspects: the basic relationship between the 1. flow rate and the pressure affects each other: the flow rate and the pressure value marked on the compressor nameplate are measured under specific conditions, but the actual
How often should the air compressor be maintained? What are the items every time? 1. The first regular maintenance time of the air compressor is 500 hours, and the oil filter, air filter and lubricating oil should be replaced for 500 hours. 2, after the initial maintenance every 3000
The maintenance cycle of screw air compressors is not fixed, but is affected by many factors, including the type of equipment, working environment, frequency of use and manufacturer's recommendations. Generally speaking, the maintenance cycle of screw air compressor can be roughly summarized as follows: 1. day
The main differences between screw air compressor frequency conversion and power frequency are reflected in the working principle, performance characteristics, energy efficiency, noise, maintenance cost, scope of application and investment cost. The following is a detailed comparison of these aspects: screw air compressor variable
