Oil Lubricated Screw Air Compressor Technology

Oil lubricated screw air compressor is a gas compression equipment widely used in the industrial field, mainly used to provide compressed air or gas. Its structural characteristics and advantages are as follows.

1. Oil Lubricated Screw Air Compressor Features

Efficient and Stable Compression Process

The oil-injected screw air compressor uses a screw to compress the air, and injects lubricating oil during the compression process, so that the temperature in the compression chamber can be controlled, reducing wear and extending the life of the equipment. This design ensures the stability of long-term continuous operation.

Low-Noise Operation

When working, the oil lubricated screw air compressor has lower noise output than other types of air compressors. This is due to its precise mechanical design and the noise reduction effect of lubricating oil, which is suitable for noise-sensitive working environments.

Good Heat Dissipation Performance

The oil lubricated screw air compressor uses lubricating oil to take away the heat generated during compression, which can effectively prevent the equipment from overheating and ensure that the machine still maintains stable operating performance under high load. This makes it perform particularly well in high temperature environments.

Easy Operation and Maintenance

The structural design of this type of air compressor is relatively simple, and maintenance requirements are relatively low. Lubricating oil not only lubricates, but also cleans the screw and sealing system, greatly reducing the frequency of equipment maintenance.

2. Choose the Right Lubricant

In order to ensure the stable operation of the screw air compressor, it is necessary to choose the right lubricant. Here are some notes on choosing lubricants:

Use Special Oil for Compressors

Screw air compressors should use special lubricants. Do not mix lubricants from different manufacturers and different models. The brand of lubricant added will be indicated in the factory information of each unit, and it should be selected and used strictly in accordance with the requirements.

Oil Performance Requirements

Oil lubricated screw air compressors should have the characteristics of anti-oxidation, anti-foaming, anti-corrosion and good wear resistance, strong water separation, appropriate viscosity, high flash point, and low pour point. These performance requirements can ensure that the lubricant plays a good lubrication, cooling, sealing and rust prevention role inside the compressor.

Control the Oil Change Cycle

In order to determine a reasonable oil change cycle, it is recommended to collect oil samples regularly every 3 to 6 months in the first two years to analyze the main indicators of the lubricant (such as viscosity, pH value, flash point, ash content, ignition point, mechanical impurities, etc.). Determining the oil change cycle according to the actual situation can ensure that the performance of the lubricant is always maintained in the best state and avoid waste and unnecessary losses.

System Cleaning and Oil Filter Replacement

After the compressor has been used for two years, it is best to use lubricating oil to perform a "system cleaning" of the oil circuit. The method is to change the oil twice in succession, and do it again after 6 hours of operation for the first time. If conditions permit, the oil circuit can be disassembled and cleaned. At the same time, the oil filter and oil filter element must be replaced together when changing the oil to ensure the cleanliness and efficient operation of the lubrication system.

Summary

Oil lubricated screw air compressors have become indispensable equipment in many industrial applications due to their high efficiency, stability and low noise.
