Talking about Lubricant and Air Compressor

At present, the mainstream product on the air compressor market is the screw air compressor. Screw air compressor gradually replaces piston air compressor with its product characteristics. For screw air compressors, most of them are oil-lubricated at this stage, so the role of lubricating oil is very important and an indispensable part.

The screw air compressor is a high-speed mechanical equipment. The metal screw inevitably generates friction during the high-speed rotation. If there is no lubricating oil isolation at the friction part, the direct contact of the screw will cause mutual wear. Make the equipment obsolete and inoperable.

The main lubrication point of the screw air compressor is the main engine. The main engine is generally divided into two types: single screw and twin screw. In terms of stability and technical content, the single screw type is higher; from the main engine's requirements on the screw part, single screw The requirements of the screw are higher than that of the twin screw. However, due to the lack of market awareness of this technology, most of them are currently twin-screw air compressors.

　　Whether it is a single screw or a twin screw, the cost and technical requirements for processing a screw are very high, and the use of lubricating oil is also very demanding. Piston air compressors generally use No. 19 lubricating oil, while screw compressors generally use No. 50-80 oil. Mainly play a role in lubrication, improve friction conditions, reduce friction, prevent wear, and at the same time can reduce power consumption, while also extending the service life of the machine.

　　 In addition, lubricating oil also plays a role in sealing, cooling, and noise reduction. Therefore, lubricating oil is an indispensable and important component of screw air compressor operation.
