What is the working principle and advantages of dry oil-free screw air compressor

Principle of dry oil-free screw air compressor

1.Introduction

Dry oil-free screw air compressor is a common air compression equipment. It adopts a unique working principle, which makes it unnecessary to use lubricating oil and avoids the oil mist pollution caused by the mixing of oil and gas in traditional lubricated air compressors. . This article will introduce the working principle and advantages of the dry oil-free screw air compressor in detail.

2.Working principle of Sollant dry oil-free screw air compressors

The working principle of dry oil-free screw air compressor is mainly divided into two steps: compression and cooling.

• Compression

The dry oil-free screw air compressor gradually compresses the air in the air inlet through the mutual meshing of the two screws. Among them, one screw is called the active screw, and the other is called the driven screw. When the two screws rotate, the air is continuously propelled and gradually compressed with the rotation of the screw. In this process, due to the design of the screw, the chamber gradually becomes smaller, the volume of the air gradually decreases, so that the pressure of the air gradually increases.

• Cooling

During the compression process, heat is generated due to the extrusion of the air by the screw. In order to prevent damage to the equipment due to excessive temperature, the dry oil-free screw air compressor adopts a cooling system to reduce the air temperature. The cooling system usually consists of an air cooler and a cooling fan. The heat is blown through the fins and fans in the cooler, reducing the temperature of the compressed air to acceptable levels.

3.Advantages of Sollant dry oil-free screw air compressors

Dry oil-free screw air compressors have the following advantages over traditional lubricated air compressors.

• No pollution

The dry oil-free screw air compressor does not need lubricating oil, so it will not produce oil mist and oil-air mixture, effectively avoiding air quality pollution. This is of great significance for industries with high air quality requirements, such as food manufacturing and medicine.

• Easy maintenance

Since there is no need to use lubricating oil, the maintenance work of the dry oil-free screw air compressor is relatively simple and does not require regular replacement of lubricating oil, which greatly reduces the maintenance cost and workload of the equipment.

• High efficiency and energy saving

The dry oil-free screw air compressor adopts advanced screw design and cooling system, which makes it have the characteristics of high efficiency and energy saving. Compared with traditional lubricated air compressors, dry oil-free screw air compressors have lower energy consumption, which can improve work efficiency and reduce energy consumption.

• Safe and reliable

Due to the oil-free lubrication system, the dry oil-free screw air compressor avoids the safety hazard of lubricating oil being flammable and explosive under high temperature and high pressure. At the same time, the oil-free screw air compressor adopts an advanced control system, which can monitor the operating status of the equipment in real time to ensure the safety and reliability of the equipment.
