Compressor Station

Our company provides customers with one-stop compressor station services in addition to a variety of screw compressors.

1. Introduction to Compressor Station
A typical air compressor station comprises four parts.
a. Air Compressor
Generally, the oil-injected twin-screw compressor is used. It is the main equipment for a compressor station and it is used to produce compressed air.

b. Air Receiver
The air receiver has three functions. The first one is to store compressed air. The second one is to stabilize the pressure of compressed air, thereby ensuring continuous stable air supply. The third function is to remove liquid water from the compressed air.

c. Air Dryer
There are mainly two types, i.e., refrigerated air dryer and desiccant air dryer. The air dryer is used to separate moisture from the compressed air. Its action principle is similar to that of air conditioning. The hot and humid compressed air is cooled to the dew point temperature, thus discharging 99% of the moisture in the air.

d. Air Filter
The air filter is used to filter out the dust and oil in the compressed air.

The compressed air produced by such a standard compressor station is very clean and dry, meeting the air consuming demands of 90% enterprises. For special industries, such as food, medicine, textile and clothing, oil-free compressor is required or multiple additional filtering devices are needed for sterilization and deodorization.

6. Fine Filter

3. Configuration Description
When two or more air compressors share one set of post - processing equipment, the post - processing equipment can be selected according to the actual air consumption. If one of the compressors is used as a backup, the post - processing equipment can be chosen according to the maximum flow rate.

The typical compressor station configuration shown in the above picture is the most commonly used one and it is applied in a variety of industries. After the compressed air enters the air receiver, it is firstly filtered in the pre-filter and then dried in the air dryer. Then, it enters the after-filter. After this filtration, the oil content of the compressed air is no more than 0.1ppm and the dust particle size is not greater than 1μm. After the air is filtered in the fine filter, the oil content does not exceed 0.01ppm and the dust particle size is less than or equal to 0.01μm.

Care and Maintenance

To make the air compressor run properly and reliably and to ensure the service life of the compressor, detailed maintenance plan is required. The compressor should be operated by specially-assigned people. Regular inspection and periodical maintenance are necessary, so as to keep the compressor clean and oil-free.

The maintenance of main components is conducted according to the following table.

Item Content Inspection or replacement cycle
500 1000 2000 3500 5000
Air Filter Element Remove surface dust and impurities The inspection or replacement cycle can be extended or shortened according to the actual dust content and other working conditions
Replace with new filter element
Intake Valve Seals Check or replace seals
Compressor Lubricant Check if lubricant is sufficient
Replace with new oil
Oil Filter Replace with a new one 500 hours for the first time
Air Oil Separator Core Replace with a new one
Minimum Pressure Valve Check the opening pressure Clean
Cooler Remove surface dust Extended or shortened depending on conditions
Safety Valve Check whether the valve acts sensitively
Oil Drain Valve Discharge moisture and dirt
Drive Belt Adjust tightness Extended or shortened according to the degree of wear
Check the degree of wear or replace
Motor Fill lubricating grease Or maintain the motor according to the motor User Guide
