There are five kinds of lubrication methods for industrial refrigerators

According to the characteristics of the compressor structure, the refrigeration equipment can be lubricated in different ways. There are five methods in the lubrication of industrial refrigerators:

1. Dripping oil lubrication method [screw chiller]

Use the oil cup and the oil pipeline to deliver the lubricating oil to the parts that should be refueled, or use the oil can to fill the lubricating oil on time.

2. Pressure lubrication method

The lubricating oil pressure lubricates the parts automatically by machinery, which is used in large and medium-sized compressors with crossheads.

3. Spray lubrication method [freezing machine]

The sprayed oil mist trails the gas into the cylinder and other lubrication places, such as super sliding vane compressors, high-pressure compressors and screw compressors all use oil injection lubrication.

4. Oil ring lubrication method

The rotating shaft drives the oil ring movably sleeved on the shaft, and the oil ring brings the oil in the oil pool into the bearing and enters the circulation lubrication.

5. Splash lubrication method [air-cooled chiller]

The oil rod installed on the connecting rod will throw the oil up and splash to the lubrication parts for lubrication, so the cylinder and the motion mechanism can only use the same kind of lubricating oil. This method is mostly used in small compressors without crosshead. But its oil is not easy to filter and it is inconvenient to operate. The oil level of industrial chillers must be strictly controlled.
