1. The working principle of the piston type micro vacuum pump is based on the reciprocating movement of the piston in the pump chamber to realize the suction and discharge of gas. The specific process is as follows:

Piston motion: The piston moves back and forth in the pump body. When the piston moves towards the bottom of the pump body, the volume of the pump chamber gradually increases, forming negative pressure. Because the gap between the piston and the pump body is very small, it can effectively prevent gas leakage.

Valve control: The suction end and the exhaust end of the piston type miniature vacuum pump are provided with a valve that can control the switching state. When the piston moves to a certain position, under the action of negative pressure, the valve will open, so that the outside gas enters the pump chamber; When the piston moves to the other side, the valve closes, preventing gas from back flow.

Gas pumping: through the continuous reciprocating movement of the piston, the gas is pumped in and out periodically. When the piston moves upward, the gas in the pump chamber is pumped into the pump body; When the piston moves down, the gas in the pump chamber is compressed and discharged from the pump body. This periodic suction and exhaust process makes the piston miniature vacuum pump work continuously to generate and maintain a certain degree of vacuum.
 

1. Working principle of vacuum pump:

The working principle of the vacuum pump is mainly to discharge the gas in the container through mechanical movement or physical and chemical methods, thereby reducing the pressure in the container. Different vacuum pump types use different working principles, but their core goal is to somehow transport gas from the low pressure area to the high pressure area, and finally achieve the generation of vacuum.
 

1. The role of micro vacuum pump is very wide, can be used in gas sampling, gas cycle, vacuum adsorption, accelerated filtration, automotive vacuum power and other occasions. Because of its small size, low noise, maintenance-free, and can operate continuously for 24 hours, micro vacuum pumps are widely used in medical, health, scientific research, environmental protection and other fields 24. In addition, the miniature vacuum pump also has the advantages of high reliability, anti-friction and wear, strong heat protection ability, good overload release ability, etc., can ensure high quality, low consumption, energy saving and environmental protection under the premise of providing a stable and reliable vacuum environment.

(5) Vacuum pump maintenance and maintenance:
 

1. Regularly check the various parts of the vacuum pump, including the motor, pump body, seals, etc. Check the running state of the motor to ensure its normal operation; Check whether there is leakage in the pump body and repair the leakage point in time.
2. Clean the inside and outside of the vacuum pump regularly to remove dust and impurities. For parts that need lubrication, add or replace lubricating oil in time. For example, rotary vane vacuum pumps require regular replacement of lubricating oil to maintain their good lubrication state
3. Some parts of the vacuum pump will be worn or damaged during long-term operation, such as seals, filters, etc. Regular replacement of these wearing parts can extend the service life of the vacuum pump.
