2901007200 Replacement Screw Air Compressor Spare Parts Atlas Copco

Product Description:

Atlas air compressor oil cut-off valve is a switch used to control the main oil path into the screw head. Its function is to cut off the oil supply to the main engine when the air compressor is shut down to prevent lubricating oil from spraying from the main engine port. To avoid oil backflow at the moment of shutdown. When the air compressor is started, too much oil will not enter the main engine, because this will cause blockage and cause the air compressor to fail to start.

When the air compressor is not in use, because the screw in the head can not be soaked in cooling oil for a long time.
For this reason, the oil cut-off valve is added into the cooling system.
When the air compressor works, the compressed gas generated will make the oil break valve open, and the cooling oil can be circulated in the system to cool the screw of the machine head.
When the air compressor is not working, the oil break valve will be in a closed state, preventing the cooling oil in the oil-water separator from being cut off to return to the screw.
Control hydraulic fluid (hydraulic) and high temperature resistance are its main characteristics.

Problems are likely to occur in the use of oil break valve:

During the use of the equipment, a small part of the impurities in the air will inevitably mix with the cooling oil. When flowing through the oil break valve, it may cause precipitation blockage, so that the oil break valve cannot be opened with the opening of the equipment, and is in a closed or semi-closed state, which will reduce the flow of the cooling oil.therefore, the cooling effect of screw head will be seriously affected.
