Oil-free vacuum pump is a mechanical vacuum pump that can operate without any oil lubrication. It has the advantages of simple structure, easy operation, easy maintenance and no pollution to the environment, so it is widely used in many fields. Oil-free vacuum pump has good durability, is a vacuum pump for vacuum and compression, and is a basic equipment with a very wide range of applications.

Product characteristics:

Environmental protection and pollution-free: oil-free vacuum pump does not produce oil smoke, does not pollute the environment, belongs to environmental protection products, so it is called the 21st century "green vacuum pump".

Easy maintenance: Because there is no need to use lubricating oil, maintenance is relatively simple, reducing maintenance work such as regular replacement of lubricating oil.

Widely used: oil-free vacuum pump can be used for a variety of vacuum operations, such as air conditioning, refrigeration equipment repair, medical equipment suction device, printing machinery, vacuum packaging, vacuum blisting, physical and chemical experiments.

Application Case "Introduction to the process of vacuuming the chamber of plasma cleaner using bipolar rotary vane vacuum pump"

The general process of oil-free vacuum pump for vacuum sample adsorption in the homogenizer can be summarized as the following steps:

First, the preparation stage

Check the equipment: Make sure that the connection between the oil-free vacuum pump and the homogenizer is correct, and all the connections are well sealed without leakage. At the same time, check the working status of the oil-free vacuum pump to ensure that it is in a normal state of use.

Sample preparation: Place the sample to be coated in the coating area of the homogenizer, and ensure that the sample is fixed and stable to prevent movement or falling off during the vacuum process.

2. Start the oil-free vacuum pump

Power on: According to the operation instructions of the oil-free vacuum pump, correctly power on and turn on the power switch. Some oil-free vacuum pumps may need to be preheated for some time to achieve the best working condition.

Observe the operating status: After starting, observe the operating status of the oil-free vacuum pump to ensure that it runs smoothly without abnormal noise or vibration.

Third, vacuum adsorption sample

Open the vacuum valve: When the oil-free vacuum pump is stable, slowly open the vacuum valve connected with the rubber leveling machine. This process should be done slowly to prevent sudden pressure changes from impacting the equipment.

Observe the pressure gauge: During the vacuum process, pay close attention to the pressure gauge reading to understand the vacuum degree of the system. According to the actual demand, adjust the vacuum speed and time until the required vacuum degree is reached.

Sample adsorption: With the increase of vacuum, the vacuum adsorption system in the homogenizer will produce adsorption effect, and the sample will be tightly adsorbed on the coating area. At this point, subsequent coating operations can begin.

Four, coating operation

Adjust coating parameters: According to the type of coating glue and the needs of the sample, adjust the coating parameters of the homogenizer, such as coating speed, coating thickness, etc.

Start coating: After the sample is stably adsorbed in the coating area, start the coating function of the homogenizer and evenly coat the glue on the surface of the sample.

5. End stage

Close the vacuum valve: When the coating operation is completed, first close the vacuum valve connected with the homogenizer to cut off the vacuum adsorption effect.

Stop the oil-free vacuum pump: then turn off the power switch of the oil-free vacuum pump to stop its operation.

Sample removal: After confirming that the vacuum has been reduced and the sample is no longer subject to adsorption force, the sample can be safely removed from the homogenizer.

Matters needing attention

During the entire operation process, pay close attention to the operating status of the oil-free vacuum pump and the homogenizer to ensure the normal operation and safety of the equipment.

Select suitable coating parameters and process conditions according to the characteristics of the coating glue and the needs of the sample.

Regular maintenance and maintenance of oil-free vacuum pumps and homogenizers to ensure long-term stable operation and extend service life.

The above is the general process of vacuuming and absorbing samples for the homogenizer. The specific operations may vary according to different equipment models and application scenarios. In actual operation, strictly follow the equipment manual and safety regulations to ensure the safety and effectiveness of the operation.
