What are the application scenarios of vacuum pressure switches

Vacuum pressure switches are widely used in multiple fields such as industry, scientific research, and daily life. They are mainly designed for scenarios where vacuum degree or negative pressure needs to be monitored to ensure the stable operation of the system or achieve automatic control. The following are some typical application scenarios:

1.Vacuum equipment and system control

Vacuum pump operation monitoring: In a vacuum pump system, a vacuum pressure switch is used to monitor the outlet pressure of the pump or the vacuum degree of the system. When the vacuum degree reaches the set value, the switch triggers the signal to control the start, stop or switch the working mode of the pump, avoiding the pump from running no-load for a long time and extending the service life of the equipment.

Vacuum packaging equipment: In the vacuum packaging process of the food, pharmaceutical and other industries, vacuum pressure switches are used to monitor the vacuum degree inside the packaging chamber. When the vacuum degree meets the requirements, the switch triggers the sealing action to ensure the sealing of the packaging.

Vacuum adsorption and clamping: In automated production lines, vacuum pressure switches are used to monitor the vacuum degree of adsorption devices (such as vacuum suction cups), ensuring that workpieces are reliably adsorbed or clamped and preventing them from falling off due to insufficient vacuum.

2. Industrial process control

Air tightness testing: In the air tightness testing of industries such as automobiles and electronics, vacuum pressure switches are used to monitor the pressure changes inside the test chamber. When the pressure change exceeds the set range, the switch triggers an alarm or stops the test to ensure product quality.

Vacuum drying and distillation: In the vacuum drying or distillation processes of the chemical, pharmaceutical and other industries, vacuum pressure switches are used to monitor the system pressure, ensuring that the process proceeds at the set vacuum degree, thereby enhancing production efficiency and product quality.

Vacuum furnaces and heat treatment: In vacuum furnaces, vacuum pressure switches are used to monitor the vacuum degree inside the furnace, ensuring that the heating process takes place in an oxidization-free environment and preventing material oxidation or deterioration.

3. Laboratories and scientific research equipment

Vacuum experimental equipment: In laboratories of physics, chemistry, etc., vacuum pressure switches are used to monitor the vacuum degree of experimental equipment (such as vacuum chambers, mass spectrometers, etc.) to ensure that the experimental conditions meet the requirements.

Low-temperature and superconducting research: In low-temperature experiments or superconducting material research, vacuum pressure switches are used to monitor the vacuum environment to prevent experimental failure or equipment damage caused by vacuum leakage.

4. Medical and Life Sciences

Medical equipment: In medical devices such as hemodialysis machines and ventilators, vacuum pressure switches are used to monitor negative pressure or vacuum levels, ensuring the normal operation of the equipment and safeguarding patient safety.

Laboratory instruments: In laboratory instruments such as centrifuges and freeze dryers, vacuum pressure switches are used to monitor the vacuum degree to ensure that experiments or processing procedures are carried out under set conditions.

5. Environmental protection and energy fields

Waste gas treatment system: In waste gas treatment equipment, vacuum pressure switches are used to monitor the pressure of vacuum pumps or adsorption devices, ensuring the efficiency of waste gas treatment and preventing the leakage of harmful gases.

Vacuum heat collection system: In solar vacuum heat collection tubes, vacuum pressure switches are used to monitor the pressure of the vacuum layer, ensuring heat collection efficiency and extending the service life of the heat collection tubes.

6. Daily Life and Consumer Electronics

Household vacuum sealing machine: In a home kitchen, a vacuum pressure switch is used to monitor the vacuum degree of the sealing machine to ensure the preservation effect of food.

Portable vacuum pumps: In devices such as car vacuum cleaners and air pumps, vacuum pressure switches are used to monitor pressure and prevent overload or damage to the equipment.

Summary

The core function of a vacuum pressure switch is to monitor the vacuum degree or negative pressure and trigger an alarm or control signal when the pressure exceeds the set range. Its application scenarios are extensive, covering multiple fields such as industrial production, scientific research experiments, medical equipment, environmental protection and energy, providing an important guarantee for the safe operation and automatic control of the system.
