1. Principle of oil and gas lubrication

The lubricating oil is delivered directly or through a distributor to a mixer connected to the compressed air. The oil and compressed air are correctly metered and distributed into the oil and gas pipelines. The oil delivered in the form of pulses is in the pipeline under the action of uninterrupted compressed air. Under the condition, the lubricating oil adheres to the inner wall of the pipe leading to the lubrication point, and gradually forms a continuous oil film. Under the action of compressed air, the lubricating oil film breaks away from the inner wall of the oil and gas pipeline in the form of fine oil droplets and is sprayed into the lubrication point. The lubrication point is thus lubricated, and the friction heat of the lubricating part is taken away by the action of compressed air to cool the lubricating part. At the same time, due to the continuous overflow of compressed air input to the lubricating parts, the intrusion of dust, water or toxic gases is effectively prevented.

2. Classification of oil and gas lubrication

1. Progressive oil and gas lubrication system

2. Large-scale pressure-maintaining oil and gasProcess lubricationsystem

3. Small oil and gas lubrication system

4. Dual-line oil and gas lubrication system

3. Scope of application

Due to its own characteristics, oil-gas lubrication is suitable for working in harsh environments such as bearings with high thermal load, high speed, dust, water or toxic gases. Compared with other forms of centralized lubrication, it has great development prospects. At present, oil and gas lubrication has been widely used in metallurgy, cement, papermaking, textile, petrochemical, electric power and other equipment, such as aluminum foil rolling mill, strip rolling mill, rotary kiln, ball mill, fiber machinery, chain conveyor, vibration machine, blower, The mineral concentrator, crusher, high-speed spinning, guide roller looper of high-speed wire rod rolling mill and continuous casting are all lubricated by oil and gas.
