How to connect screw air compressors in series
The connection method of screw air compressors in series mainly depends on what purpose you want to achieve, such as increasing exhaust pressure or increasing exhaust volume.
If you want to increase exhaust pressure：
Usually several screw air compressors are connected in series, that is, the exhaust port of one air compressor is connected to the air inlet of another air compressor. In this way, the air will pass through each air compressor in turn for compression, thereby increasing the overall exhaust pressure.
In terms of electrical control, it is necessary to ensure that each air compressor can be started and stopped in order. Generally speaking, it can be achieved by setting up a pressure sensor and a control circuit. When the system pressure is insufficient, the first air compressor is started first; if the pressure is not enough, the second air compressor is started again, and so on. When the system pressure reaches the preset threshold, the air compressor stops in the reverse order.
If you want to increase your exhaust volume：
Multiple screw air compressors can be connected in parallel to supply air to the same set of pipelines.
In terms of electrical control, it is necessary to ensure that each air compressor can be independently controlled and started and stopped according to the air demand of the system. This can be achieved by setting up a total pressure sensor and control circuit. When the system pressure is insufficient, the air compressors are started in turn; when the system pressure reaches a preset threshold, the air compressors are stopped in turn.
precautions：
- Before wiring, be sure to cut off the power supply to ensure safety.
- When wiring, operate strictly in accordance with electrical specifications to avoid short circuits or poor contacts.
- When connecting air compressors in series or parallel, the rated current and power of the air compressor should be considered to ensure that the circuit can withstand it.
- It is best to ask a professional electrical engineer for design and wiring to ensure the stability and safety of the system.
