What are the five design principles of wireless display?
2. Reliability. Due to the particularity of the environment used by the wireless LED display information distribution system, the relative stability of the system must be guaranteed.
3. Scalability. The system should have good scalability. When the number of terminals increases, the scope of use is expanded, the system functions are enhanced, and the upgrade can be smoothly upgraded to protect investment.
4. Practicality. The operation of the whole system is convenient and concise, and the goal of colleges and universities is to fully reflect the characteristics of fast communication, and it is convenient for operators to process and publish information, so that management can keep abreast of various statistical information.
5. Confidentiality. Strict authority management is implemented for system management. Only keys with certain permissions can be accessed, monitored, implemented, managed, and controlled to ensure system security.
Peristaltic Metering Pump Characteristic
1. Clean and pollution-free: the fluid only passes through and touches the Peristaltic Pump hose.
2. High precision: constant current, reproducibility of up to 0.5%, and flow can be precisely adjusted.
3. Low shear force: It is an ideal tool for conveying shear-sensitive and corrosive fluids.
4. Corrosion resistance: it can transport various fluids, such as organic solvents and corrosive liquids.
5. Idling and dry operation: air or gas-liquid-solid three-phase mixed transportation can also be transported.
6. Possess self-priming ability: self-priming, no need to fill the pump, no need to empty.
7. It has the function of a shut-off valve, does not siphon, has no seals, and has the functions of a shut-off valve and a check valve.
8. Two-way conveying function: reverse pumping and back-suction functions can be realized by changing the direction of the pump runner.
9. Simple maintenance: only need to replace the peristaltic pump hose, no valve and seal replacement.
