How much do you know about the classification of Molecular Pump supplier? Let's take a look at it briefly!
There are many forms of compound Molecular Pump supplier. According to the structure, there are two main types: one is the series combination of turbine blades and disc traction pump; the other is the series combination of turbine blades and drum traction pump. The turbine stage is mainly used to increase the pumping speed of the pump. Generally, the blade shape is used to increase the pumping speed, and the number of stages is within l0. The traction stage is mainly used to increase the compression ratio of the pump and increase the outlet pressure of the pump.
The disc traction stage is to open several grooves on the plane of the flat disc according to a certain rule, and then connect several discs in series. The mould line includes Archimedes spiral, logarithmic spiral, and circle Arc etc. When pumping air, the high-speed rotating disk "drags" the gas molecules to make them flow reciprocally back and forth along the groove from the inside to the outside and from the outside to the inside, so as to achieve the purpose of pumping.
The cylindrical traction stage is a groove with a certain cross-sectional shape on the cylindrical surface of the cylindrical rotor or stator, such as rectangular, arc-shaped, triangular and other shapes of multi-head spiral grooves. Since the linear groove of the simple traction pump is opened on the outer surface of the rotor cylinder or the inner surface of the pump body, the higher linear velocity of the outer circle of the cylinder can be fully utilized to transfer the momentum of the gas molecules and improve the pumping effect of the pump. In the design and manufacture, you can achieve a more ideal pumping effect by changing the angle between the spiral groove channel and the pumping direction (helix angle).
The above is a brief introduction to the classification knowledge of Molecular Pump supplier.
