1. Understand the working principle of the vacuum generator
The working principle of the vacuum generator is to spray compressed air at high speed through the nozzle, thereby forming a jet at the nozzle outlet. This jet will produce a suction effect, causing the air around the nozzle to be continuously sucked in, thereby reducing the pressure in the adsorption chamber to below atmospheric pressure, and finally forming a certain vacuum degree. Understanding this principle helps to grasp the key factors of vacuum regulation more accurately.
2. Choose a suitable vacuum gauge and installation location
Vacuum gauge selection: To ensure the accuracy of vacuum measurement, a suitable vacuum gauge should be selected, and its accuracy and stability should meet the use requirements.
Installation location: Install the vacuum gauge in the vacuum system to ensure that it can correctly read the pressure in a low-pressure environment. At the same time, care should be taken to avoid external interference at the installation location, such as vibration, temperature changes, etc., to ensure the accuracy of the measurement results.
3. Adjust the high-speed solenoid valve
The high-speed solenoid valve plays a role in controlling the on-off of compressed air in the vacuum generator, thereby achieving the adjustment of the vacuum degree. The specific adjustment methods are as follows:
Solenoid valve response time: By optimizing the response time of the solenoid valve, the on-off of compressed air can be adjusted faster, thereby achieving rapid adjustment of the vacuum degree.
Solenoid valve opening control: Some solenoid valves support opening adjustment. By adjusting the opening of the solenoid valve, the flow of compressed air can be controlled, thereby achieving fine adjustment of the vacuum degree.
4. Adjust the internal parameters of the vacuum generator
Nozzle design: The shape, size and material of the nozzle will affect the generation and entrainment effect of the jet, thereby affecting the vacuum degree. Therefore, more accurate vacuum degree adjustment can be achieved by optimizing the nozzle design.
Receiving (mixing) pipe design: The design of the receiving (mixing) pipe will also affect the formation and stability of the vacuum degree. By adjusting its length, diameter and other parameters, the vacuum degree adjustment effect can be further optimized.
5. Regular maintenance and care
In order to ensure the long-term stable operation of the vacuum generator and achieve accurate vacuum degree adjustment, regular maintenance and care should be carried out:
Cleaning and inspection: Regularly clean the dirt and dust inside and outside the vacuum generator, check the wear and damage of each component, and replace the seriously worn components in time.
Calibration and testing: Regularly calibrate the vacuum gauge to ensure the accuracy of its measurement results. At the same time, the vacuum generator is tested for performance to ensure that its various performance indicators meet the use requirements.
6. Combined with actual application scenarios
In actual applications, the appropriate vacuum generator model and configuration should be selected according to the specific use scenarios and needs. For example, in situations where fast response and precise control are required, a vacuum generator with a high-speed solenoid valve and a precision control system can be selected.
By understanding the working principle of the vacuum generator, selecting a suitable vacuum gauge and installation location, adjusting the high-speed solenoid valve, adjusting the internal parameters of the vacuum generator, regular maintenance and care, and combining with actual application scenarios, more accurate vacuum degree adjustment can be achieved with high-speed solenoid valve integrated vacuum generator.
