Air compressor is a kind of equipment to compress and store air, which is widely used in industry, agriculture, medical treatment, automobile and other fields. The pressure switch of an air compressor is an important part to control the start and stop of the air compressor, which can automatically regulate the operation of the air compressor according to the set pressure range.
What is the working principle of air compressor pressure switch?
The core component of an air compressor pressure switch is an elastic element, usually a spring or a diaphragm. When the outlet pressure of the air compressor changes, the elastic element deforms and moves a contact. The movement of the contact changes the on/off state of the circuit, thus controlling the turning on and off of the power to the air compressor.
The pressure switch of an air compressor usually has two contacts, corresponding to the highest and lowest pressure points. When the outlet pressure of the air compressor reaches the maximum pressure point, one of the contacts of the pressure switch will break the circuit and stop the air compressor. When the outlet pressure of the air compressor drops to the minimum pressure point, the other contact of the pressure switch will open the circuit and restart the air compressor. In this way, the pressure switch ensures that the air compressor operates within a reasonable pressure range and avoids overpressurization or underpressurization.
What are the functions and benefits of an air compressor pressure switch?
The main functions and advantages of pressure switches for air compressors are as follows:
Protects the air compressor and air storage tank. Pressure switches prevent air compressors and air storage tanks from bursting due to excessive pressure, causing injury and equipment damage.
Saving energy and cost. The pressure switch can automatically control the air compressor on and off according to the actual need, avoiding the air compressor from idling or overworking, thus saving electricity and maintenance cost.
Improve working efficiency and safety. Pressure switch can ensure the air compressor to provide stable and suitable pressure to meet the needs of different applications, improve working efficiency and safety.
How to choose and adjust the pressure switch of air compressor?
The selection and adjustment of pressure switch of air compressor should be considered according to the type, specification, application, environment and other factors of air compressor. Generally speaking, the following points should be noted:
Select the appropriate pressure range. The pressure range of the pressure switch should be suitable for the outlet pressure of the air compressor and should not be too large or too small. Too large a pressure range will result in frequent starting and stopping of the air compressor, affecting the life and stability of the equipment. Too small a pressure range will result in prolonged operation of the air compressor, increasing energy consumption and wear and tear.
Select the appropriate interface size. The interface size of the pressure switch should match the outlet pipe of the air compressor and should not be too large or too small. Too large a port size will cause pressure loss, affecting the accuracy and stability of the pressure. Too small a port size can cause flow restrictions, affecting air supply and quality.
Select a suitable mounting location. The pressure switch should be mounted as close as possible to the outlet of the air compressor to minimize pressure fluctuations and delays. At the same time, the pressure switch should be avoided to be affected by unfavorable factors such as temperature, humidity, vibration, and contamination to ensure the proper operation and life of the pressure switch.
Adjust the proper pressure point. The pressure point of the pressure switch should be adjusted according to the use and demand of the air compressor, and there are generally two methods: one is to change the preload of the elastic element by rotating the screws or knobs on the pressure switch, so as to change the size of the pressure point; the other is to change the size of the pressure point by replacing the elastic element of different specifications. When adjusting the pressure point, care should be taken to keep the difference between the highest pressure point and the lowest pressure point within a reasonable range, generally 20%~40%.
The pressure switch of the air compressor is an important part to control the start and stop of the air compressor, which can automatically adjust the running status of the air compressor according to the set pressure range. The working principle of the pressure switch of air compressor is to use the deformation of the elastic element to push the movement of the contact, so as to change the on-off state of the circuit. The function and advantage of air compressor pressure switch is to protect the air compressor and air storage tank, save energy and cost, improve working efficiency and safety. The selection and adjustment of air compressor pressure switch should be based on the type, specification, usage, environment and other factors of air compressor, pay attention to the selection of appropriate pressure range, interface size, installation location and pressure point.
