Fixed-chip vacuum pump working principle and structure
[Asia Fluid Network News] fixed-chip vacuum pump is a structure is very simple, long service life, easy maintenance vacuum pump. However, the pumping speed requires a large, resulting in difficult to ensure that the slider seal and seldom used. However, understanding the principle of fixed-chip vacuum pump for the subsequent improvement and promotion of related products of great significance, with the continuous expansion of China's market demand, although the fixed-chip vacuum pump has its limitations, but if you can continue to improve its shortcomings, I believe that after Of the market, its status is still immeasurable. The working principle and structure of the fixed-plate vacuum pump The working principle and structure of the fixed-plate vacuum pump are shown in the figure: There is a rotating eccentric rotor (2) in the cylindrical pump chamber (1) of the fixed-plate vacuum pump, (3) which is capable of sliding up and down, and presses the rotor by means of a spring (4) to separate the pump chamber into two spaces A and B. As the rotor rotation angle is different, so that the two space volume alternately increase or decrease, and ultimately to achieve the role of inhalation and exhaust. During the operation of the stator-type vacuum pump, the vane reciprocates vertically and slides on the rotor surface. The spring acts on the vane through a generally angled lever (5). All moving surfaces in a fixed-plate vacuum pump are covered with an oil layer to create an oil seal between the suction and exhaust chambers. In addition, the oil is also filled with all the harmful space inside the pump chamber. The working principle of the fixed-plate vacuum pump is not complicated. It has single-stage and bipolar points. The ultimate vacuum of the bipolar can reach 10-1pa, but its working range is relatively small because of its limited performance. For the user, the choice of a suitable own product is essential, even if this product is still inadequate, but as long as understand the working principle, make the best use of it, and with the continuous improvement of science and technology, the market of fixed-plate vacuum pump Still worth the wait.
