Lubrication system of centrifugal compressor

1. The main role of centrifugal compressor lubrication

A stable lubricating oil film is formed between the relatively moving friction surfaces to isolate the direct contact of the friction surfaces, thereby reducing wear, reducing friction power consumption, and prolonging the service life of friction elements.

A protective film is formed on the metal surface by physical adsorption or chemical adsorption to prevent the friction surface from rusting.

It takes away most of the heat generated on the friction surface by the way of lubricating liquid circulation, so as to play the role of cooling the friction surface.

Through the lubrication flow, the dirt attached to the surface of the part and the wear debris generated by abrasion are taken away to achieve the effect of cleaning the friction surface and seal the working volume of the compressed gas. air compressor ends

2. The composition of the lubrication system of the centrifugal compressor

In order to ensure the formation of a stable lubricating oil film between the sliding bearing and the surface of the main shaft, generally centrifugal compressors adopt a forced pressure oil circulation lubrication method. The lubrication system is mainly composed of a lubricating oil tank, a main oil pump, an oil cooler, a high-level oil tank, valves and pipelines. During normal operation, the lubricating oil in the oil tank is sucked into the filter through the pump, pressurized by the lubricating oil pump, and then supplied by the oil cooler, oil filter, and regulating valve to provide clean lubricating oil for the system to meet the requirements of the friction pairs in the compressor unit. The need for lubrication and sealing of the working volume. air compressor ends

Lubricating oil tank

The lubricating oil tank is the equipment for lubricating oil supply, recovery, sedimentation and storage. There is a heater inside to heat up the lubricating oil before starting up to ensure that the lubricating oil temperature rises to the range of 35-45 degrees Celsius when the unit starts to meet the needs of the unit to start up and run. The oil return port and the suction port of the oil pump are generally located on both sides of the oil tank, with filtering baffles in the middle, so that the lubricating oil flowing back to the oil tank has time for sedimentation of impurities and gas release, thereby ensuring the quality of the lubricating oil. The side wall of the oil tank is provided with a liquid level indicator to monitor the change of the lubricating oil level in the oil tank.

Lubricating oil pump

The lubricating oil pumps of centrifugal compressors are generally equipped with two main and auxiliary oil pumps, the main oil pump is running, and the auxiliary oil pump is standby. When the main oil pump or the oil circuit system fails and the system oil pressure drops to a certain value, the auxiliary oil pump automatically starts and puts into operation to provide an appropriate amount of lubricating oil for each lubrication point of the unit. air compressor ends

Oil cooler

The temperature of the lubricating oil returning to the tank usually rises. Such lubricating oil must be cooled before recirculating into the lubrication part. The oil cooler is used to cool the lubricating oil after the oil outlet pump to control the temperature of the oil entering the lubrication part. Two oil coolers are generally configured, one for use and the other for standby, which can be switched for use when necessary; when the cooling effect of one is not good, the two can be used at the same time.

Oil filter

The lubricating oil filter is installed at the outlet of the pump to filter the compressor lubricating oil to prevent foreign or machine-generated pollutants from entering the system. It is an effective measure to ensure the quality of lubricating oil. In order to ensure the safe operation of the unit, two filters are equipped, one in operation and one in standby.

High fuel tank

The high-level oil tank is a protective device. When the main and auxiliary oil pumps are interrupted, the lubricating oil in the high-level oil tank enters the lubrication parts along the oil pipe by gravity to maintain the lubrication needs of the unit. The oil storage capacity of the high-level oil tank should be maintained for at least 5 minutes of oil supply time. air compressor ends
