Compared with ordinary vacuum pumps, the R300 laboratory oil-free vacuum suction pump has a significant feature that its front end is equipped with a set of specially designed vacuum regulating valves, which can be used by suction filtration customers. However, many customers still do not understand the role of this component and the specific method of use in the process of use, and cannot play the role of accessories well. cryotubes briefly introduces the structure of the accessory, the role of each component, and how it is being used. The control valve of R300 oil-free vacuum suction pump is divided into 5 parts, the name and function of each part are as follows:
Pump tube interface: used to connect the pipeline, the vacuum suction pump and the filter bottle are connected through the pipeline to form A system. The modified interface adopts the pagoda type, which can connect hoses of different thicknesses, and has strong versatility, including hoses with inner diameters of 4mm-8mm can be used. If the filter device uses other specifications of the pipeline, you can also ask the dealer to replace the interface.
2. Vacuum gauge: It is used to observe the vacuum degree, in order to understand the working state of the instrument and whether it is sucked and filtered normally again. 3. Regulating valve: Located at the bottom of the buffer cup, it is a rotary knob that is used with a vacuum gauge to adjust the degree of vacuum to change the filtration speed of the system.
4. Buffer cup: A buffer is formed between the inlet of the regulator valve and the inlet of the vacuum pump to prevent the filtrate from being sucked back during suction filtration and damaging the vacuum gauge. 5. Filter element: It can prevent dust, particles or water vapor from being directly sucked into the vacuum pump. The main function of these components is to perform vacuum adjustment and prevent the filtrate from sucking back. The specific methods of use are as follows:
