Is the pressure from the factory gas source to each node the same?

The pressure from the plant gas source to each node is usually not the same this conclusion is mainly based on pipeline pressure loss, equipment demand difference, system design characteristics and dynamic changes in actual operation. The following is a detailed analysis of this issue:

1. pipeline pressure loss

1. pipe length and diameter: The length and diameter of the pipeline from the gas source to each node are different, which will cause the pressure to gradually decrease during the transmission process. Generally speaking, the longer the pipe and the smaller the diameter, the greater the pressure loss.
2. Pipe material and roughness: Pipe material and inner wall roughness also affect pressure loss. The rough inner wall will increase the friction between the fluid and the pipe wall, thus increasing the pressure loss.
3. gas flow rate: The higher the flow rate of the gas in the pipeline, the greater the pressure loss. Therefore, in the case of a certain output power of the gas source, if the gas demand of a certain node is large, resulting in an increase in the flow rate, the pressure of the node will be relatively low.

2. Equipment Demand Variance

1. type of gas-using equipment: Different gas equipment in the factory may have different requirements for air pressure. For example, some precision equipment may require higher air pressure to ensure its normal operation, while some common equipment may require lower air pressure.
2. Quantity of gas-using equipment: The number of gas-using equipment used at the same time will also affect the pressure of each node. If a large number of devices are used at the same time in an area, the air pressure in that area may be relatively low.

3. System Design Features

1. branch pipe design: The factory gas source system usually adopts a branch pipeline design to distribute the gas source to various areas or equipment. This design itself will lead to differences in the pressure of different nodes.
2. Setting of pressure regulating device: In order to meet the air pressure requirements of different equipment, a pressure regulating device is usually set in the air source system of the factory. These devices can adjust the air pressure at each node as needed, but may also cause pressure differences between different nodes.

Dynamic changes in the actual operation of the 4.

1. Fluctuation of air source output the output power of the air source (such as air compressor) may fluctuate due to many factors, such as equipment aging and improper maintenance. This fluctuation will cause the air pressure output by the air source to be unstable, and then affect the pressure of each node.
2. Start and stop of pneumatic equipment: The start and stop of the gas equipment will also affect the pressure of each node. When a device starts, it consumes a certain amount of gas, causing the pressure in the area to drop; when the device stops, the pressure gradually recovers.
