Installation Requirements for Screw Air Compressor Piping

The available materials for screw air compressor supply pipelines are roughly divided into pressure hoses (suitable for small screw air compressors or temporary gas use), galvanized pipes, moderate prices, widely used in the installation of screw air compressor pressure pipelines, aluminum alloy super pipes, suitable for customers with high requirements on factory image, gas supply quality, gas supply stability, etc. At present, the price of aluminum alloy super pipes is slightly higher than that of galvanized pipes, but with the increase of customer demand, the reduction of material prices, the convenience of installation of aluminum alloy super pipes, the guarantee of compressed air quality, and the reduction of compressed air loss have determined the future trend of the market.

Screw air compressor pipeline installation needs to meet the following 10 requirements:

1. The air supply port of the screw air compressor unit needs to install a stop valve, and the pipeline must have a slope of 1 ° -2 ° to facilitate the discharge of condensed water in the pipeline.

2. The pressure drop of the piping shall not exceed 5% set by the screw air compressor, so it is best to choose a pipe diameter larger than the design value when piping.

3. The branch pipeline must be connected from the top of the main pipeline to prevent the condensed water in the pipeline from flowing down to the working machine or back to the screw air compressor group.

4. Tools to be lubricated should be equipped with a triple combination (air filter, pressure regulator, oil feeder) to maintain the service life of the tools.

5, the main pipe can not be arbitrarily reduced, if it is necessary to reduce or enlarge the use of reducing pipe, otherwise there will be mixed flow at the joint, will lead to a great pressure loss, at the same time also has a great impact on the life of the pipeline.

6. If there are purification buffer equipment such as air storage tank and dryer after the air compressor, the ideal piping should be air compressor + air storage tank + dryer. In this way, the gas storage tank can discharge part of the condensed water, and the gas storage tank also has the function of reducing the temperature of the gas. The air with lower temperature and less water content enters the dryer again, which can reduce the load of the dryer.

7, the amount of air is very large and the time is short, it is best to install a gas tank as a buffer, can reduce the number of air compressor empty heavy car, the air compressor is of great help.

8. For compressor air with system pressure below 1.5Mpa, the flow rate in the delivery pipe must be below 15m/sec to avoid excessive pressure drop.

9. Minimize the use of elbows and various valves in the pipeline to reduce pressure loss.

10. The ideal piping is that the main pipeline surrounds the entire plant, so that all aspects of compressed air can be obtained at any position. For example, when the gas consumption of a branch line suddenly increases, the pressure drop can be reduced. And in the ring main line configuration of the appropriate valve, to facilitate maintenance cut off use.
