5V DC mini vacuum pump for vacuum sealer

The specific operation process of using a Mini Vacuum Pump for vacuum preservation

1. Preparation: First, ensure that the Dc Mini Vacuum Pump is placed on a flat tabletop and its power cord is plugged into a power socket. Next, connect the inlet of the vacuum pump to the outlet pipeline of the food packaging bag that needs to be preserved, ensuring a tight connection to prevent gas leakage.

2. Start the vacuum pump: Turn on the power switch of the micro diaphragm vacuum pump and adjust the speed control knob to reach the appropriate working speed. Observe the working status of the vacuum pump to ensure its normal operation.

3. Start vacuuming: After the vacuum pump is running normally, open the intake valve of the food packaging bag and start vacuuming. During the vacuum pumping process, it is necessary to observe the reading of the vacuum gauge in order to adjust the working speed of the vacuum pump in a timely manner.

4. Achieve the required vacuum degree: When the vacuum gauge shows the required vacuum degree, close the intake valve of the food packaging bag and stop vacuuming. At this point, the air inside the food packaging bag has been extracted, creating a vacuum environment that helps extend the shelf life of the food.

5. Turn off the vacuum pump: Turn off the power switch of the Mini Electric Vacuum Pump and wait for the vacuum pump to stop running. Disconnect the pipeline connection between the vacuum pump and the food packaging bag.

6. Complete vacuum preservation: Now, the food packaging bags are in a vacuum state, which can effectively extend the shelf life of the food. Store the packaging bag in a suitable place, avoiding direct sunlight and high temperatures.

How can a Micro Electric Vacuum Pump achieve vacuum preservation?

1. Establish connection: First, connect the inlet of the DC Electric Vacuum Pump tightly to the outlet pipeline of the food packaging bag that needs to be preserved, ensuring that there is no possibility of gas leakage.

2. Start the vacuum pump: After the packaging bag is connected to the vacuum pump, start the vacuum pump to extract air from the packaging bag.

3. Air extraction: The Portable Vacuum Pump continuously moves back and forth through its internal diaphragm to extract and discharge the air from the packaging bag into the external environment. This process will continue until the air inside the packaging bag is extracted to a certain degree, forming a certain degree of vacuum.

4. Sealed storage: When the required vacuum degree is reached, close the valves of the vacuum pump and packaging bag to keep the packaging bag in a low oxygen or anaerobic state. In this way, the food inside the packaging bag is in a relatively stable preservation environment, which can effectively extend its shelf life.

Technical Specification

How does a Small Electric Vacuum Pump ensure sealing during the vacuum pumping process?

1. Choose appropriate sealing materials and components: High quality and durable materials such as silicone, rubber, or special sealants should be selected for the connection and sealing components of micro diaphragm vacuum pumps. These materials should have good elasticity and corrosion resistance to ensure that they can still maintain good sealing performance during long-term use.

2. Correct installation and connection: When installing and connecting various components of the vacuum pump, it is essential to ensure that the connections are tight and leak free. Pay special attention to checking whether the threads, flanges, etc. at the connection are installed correctly, and whether there is any looseness or damage.

3. Regular inspection and maintenance: Regularly check the sealing performance of the vacuum pump, including the wear of sealing components and whether the connections are tight. If a decrease in sealing performance or leakage is found, the sealing components should be replaced or the connection should be tightened in a timely manner.

4. Avoid excessive use: When using micro diaphragm vacuum pumps, prolonged continuous operation should be avoided to avoid excessive wear or aging of sealing components. It is recommended to arrange work and rest time reasonably according to the actual situation.

5. Pay attention to the usage environment: Avoid using the vacuum pump in harsh environments such as humidity, high temperature, or corrosive gases to avoid adverse effects on the sealing performance.

6. Take additional sealing measures: If used in special circumstances such as high temperature, high pressure, or high vacuum, additional sealing measures may be required, such as wrapping sealing tape or applying sealant at the connection.

What factors affect the pumping efficiency of micro diaphragm vacuum pumps?

1. Steam pressure: Low steam pressure or pressure fluctuations may have a significant impact on the capacity of vacuum pumps. The steam pressure should be stable and not lower than the required working pressure to ensure the stable performance of the Small Vacuum Electric Pump.

2. Cooling water circulation: If the cooling water supply is insufficient, the condenser may become hot, causing an increase in airflow sound, a rapid decrease in vacuum degree, and even steam may return to the exhaust pipe, thereby affecting the extraction efficiency

3. nozzle status: The nozzle is an important component that affects the performance of the vacuum pump. If the nozzle is installed incorrectly, misaligned, blocked, damaged, corroded or leaking, it may lead to a decrease in pumping efficiency.

4. Container size: The size of the container also affects the pumping efficiency. A larger container can slow down the rate of vacuum generation and increase the time required to reach a higher vacuum degree, thereby affecting water absorption and pumping efficiency.

5. Vacuum degree: The better the vacuum degree of the vacuum pump, the less residual gas in the sealed container, the thinner the gas, and the greater the pressure difference between the container and the external environment, which can improve the pumping efficiency.

6. Operating environment: The pollution of the system caused by the extracted gas may also affect the extraction efficiency. For example, during the disposal process of molten steel, a lot of gas is released, and small particles such as fine oxide scales may be sucked into the vacuum pump. These small particles may accumulate and adhere to the pump body, reducing the flow conductivity of the pumping pipeline, prolonging the pumping time, and reducing the pumping efficiency of the pump.

What are the common causes and solutions of faults in micro diaphragm vacuum pumps?

Common Fault 1: DC Pump unable to start or difficult to start

Possible causes: power supply issues, motor malfunctions, or excessive accumulation of impurities in the pump.

·Solution: Check if the power supply is normal, if the motor is damaged, and clean the inside of the pump to remove impurities.

Common Fault 2: Unstable pump operation or excessive noise

Possible reasons: Unstable installation of the pump, worn bearings, or damaged diaphragm.

Solution: Reinstall the pump to ensure its stability, replace worn bearings, or repair or replace damaged diaphragms.

Common fault three: The pumping speed of the pump decreases or cannot reach the expected vacuum degree

·Possible reasons: decreased sealing performance of the pump, air leakage in the intake pipeline, or scaling inside the pump.

Solution: Check and replace the seals, check and repair the leakage points in the intake pipeline, and clean the inside of the pump to remove scaling.

Common Fault Four: Pump Overheating

·Possible causes: prolonged continuous operation of the pump, cooling system malfunction, or poor internal lubrication of the pump.

·Solution: Rest the pump properly, inspect and repair the cooling system, and ensure good lubrication inside the pump.

Common Fault 5: Pump Oil Leakage

·Possible causes: aging of seals, improper installation, or damage to pump body.

·Solution: Replace the seal, ensure the correct installation of the pump, and check if the pump body is damaged and repair it in a timely manner.
