The above process is based on the different scales of the pharmaceutical factory, different types of air compressors. Table 1 Particles, oil, water quality grades in compressed air. Name grade Particle size (um) Particle content (mg/m3) Water content (pressure dew point) °c Oil content (mg/m3) Table 2 Compressed air filter classification, principle, structure and role classification Basic principle and structure action Pre-filter inertial collision, medium-effect fiber, sintered material filter 1um or more particle precision filter diffusion The interception effect is mainly used. The ultrafine fiber combination filters out the diffusion effect of the ultra-precision filter of 0.011 um or more. The ultra-fine fiber combination filters out the activated carbon filter of 0.0111 or more. The activated carbon adsorption + ultrafine fiber filter removes the oil vapor. The odor sterilization filter is mainly used for diffusion effect, and the ultra-efficient and moisture-resistant material is used to filter bacteria and phages. The above page is connected to page 163, waiting for the SPI to send the signal to the clock input/output pin, and the SDI is the latch signal. . When the data to be transmitted is transmitted, the signal output display can be realized by giving a latch signal to the SD. 4-digit digital tube display data sub-program bit selection code segment selection code 3. Conclusion From the above examples, it can be seen that among the commonly used industrial instrument display devices, the LED display is driven by the single-chip microcomputer and the shift register 74HC595, the wiring is simple and practical, and the cost is low. , high reliability. Under the I/O line, the scheme is more ideal.
