Oil-free vacuum pumpIt has the advantages of simple structure, easy operation, convenient maintenance, and no environmental pollution. The Punok series oil-free vacuum pump has good durability and is a dual-purpose vacuum pump for vacuum pumping, compression, and is a basic equipment with a wide range of applications for obtaining vacuum.

1、 Instructions for using oil-free vacuum pump

Before using the oil-free vacuum pump, please carefully read the corresponding model (oil-free vacuum pump structure diagram) to understand the functions of each component.

1. Before use, please carefully check whether all components are connected correctly, including the connection between the oil-free vacuum pump tube and the vacuum pump, the connection between the vacuum pump tube and the supporting equipment, whether the vacuum regulating valve knob is tightened, and whether the plastic buffer cup and the meter head are tightened, to ensure that there is no air leakage in the above areas.

2. Connect the power supply, turn on the power switch on the vacuum pump, and start the vacuum pump.

3. During the working process, the vacuum degree and pumping speed can be adjusted through a vacuum regulating valve.

4. After work, turn off the device. (In some cases, it is recommended not to immediately turn off the device after use. Instead, unplug the hose connecting to the oil-free vacuum pump and allow the pump to continue pumping air for 0.5-1 hour. For specific details, please refer to the third item on precautions for using oil-free vacuum pumps in this article.)

2、 Function of structural components of oil-free vacuum pump

1. Extraction interface: used to connect vacuum pump hoses

2. Vacuum gauge: displays vacuum degree

3. Filter element: used to remove water vapor

4. Buffer cup: used to prevent liquid from being directly drawn into the vacuum pump. If liquid or impurities enter the cup, the buffer cup can be unscrewed, poured out, and cleaned

5. Power switch: used to turn on and off the vacuum pump

6. Vacuum regulating valve: used to adjust the vacuum degree and pumping speed

3、 Precautions for using oil-free vacuum pump

1. This device is not suitable for suctioning highly corrosive gases or gases that are prone to volatile emissions. If a small amount of organic gas is sucked in during the operation of the vacuum pump, in order to prevent internal component corrosion caused by organic gas condensation, air should be evacuated for at least 0.5-1 hour. If the gas being pumped is corrosive, please choose a corrosion-resistant oil-free vacuum pump or switch to other vacuum pump products.

2. It is forbidden to directly suck liquid into the vacuum pump. If a small amount of liquid is sucked in during the operation of the vacuum pump, do not immediately shut down the vacuum pump after use. Instead, evacuate the air for at least 0.5-1 hour to empty it. If the container being pumped contains a large amount of liquid, it is more suitable to use a water ring vacuum pump.

3. Vacuum pumps should not extract hot gases. When the temperature of the pump body exceeds 90 ℃, overheat protection will be activated; After the temperature drops below 60 ℃, it can be used normally. If it is necessary to pump high-temperature gas for a long time, it is recommended to add a cold trap in front of the vacuum pump to reduce the temperature of the gas pumped into the vacuum pump.

4. Maintain good ventilation to facilitate heat dissipation and extend lifespan.

5. Precautions for using the vacuum drying oven: Please first open the vacuum valve of the vacuum drying oven, start the vacuum pump to evacuate the drying oven, and then start heating the vacuum drying oven after reaching the required vacuum degree. The vacuum pump is not easy to work on the heated vacuum drying oven for a long time. Please refer to Note 3 for details.

6. Precautions for use in filtration devices or waste liquid suction: It is important to promptly pour out the liquid from the collection bottle. Directly pumping the liquid into the vacuum pump can easily cause damage to the vacuum pump. If a small amount of liquid is accidentally drawn into the pump during use, please do not immediately turn off the vacuum pump. It is recommended to immediately remove the pump tube connected to the vacuum pump and allow the vacuum pump to evacuate for at least 0.51 hours. If a large amount of liquid is accidentally drawn into the vacuum pump, please contact the dealer immediately.
