1. Material: Pavement sign boards are typically made of durable materials such as aluminum, steel, or plastic. Pavement Sign Board,Pavement Board Signs,Pavement Advertising Boards,Swinger Pavement Signs SUZHOU JH DISPLAY&EXHIBITION EQUIPMENT CO.,LTD , https://www.jh-snapframe.com
2. Size: The size of pavement sign boards can vary depending on their intended use. They typically range from 18 inches to 36 inches in width and 24 inches to 48 inches in height.
3. Weight: The weight of pavement sign boards can vary based on the material used. Aluminum sign boards are lightweight, while steel and plastic sign boards can be heavier.
4. Shape: Pavement sign boards are typically rectangular in shape, but can also be square or circular.
5. Graphics: Pavement sign boards can be printed with graphics or text on one or both sides. Graphics can be printed using a variety of methods, including vinyl graphics, digital printing, or screen printing.
6. Frame: Pavement sign boards may have a frame that holds the sign in place and provides stability. Frames can be made of the same material as the sign board or can be a different material.
7. Base: The base of pavement sign boards can be weighted to provide stability in windy conditions. Some pavement sign boards have a water-filled base, while others have a sand-filled base.
8. Weather resistance: Pavement sign boards are designed to withstand outdoor weather conditions, such as rain, wind, and sunlight. Some sign boards are treated with UV-resistant coatings to prevent fading.
9. Portability: Many pavement sign boards are designed to be portable, with wheels or a handle for easy transport. This makes them ideal for businesses that need to move their signage around frequently.
Solenoid valve failure will have a direct impact on the switching valve and regulating valve action, the common fault solenoid valve does not act, should be checked from the following aspects: (1) Solenoid valve loose or thread head off, the solenoid valve can not be tight, tight Thread fixed head. (2) Solenoid coil burned out, remove the solenoid valve wiring, with a multimeter to measure, if the open circuit, the solenoid valve coil burned out. The reason is the coil damp, resulting in poor insulation and leakage flux, causing the coil current is too large and burned, so to prevent rain into the solenoid valve. In addition, the spring is too strong, the reaction force is too large, the number of coil turns is too small, and the suction is insufficient, the coil can also be burned. In emergency, the manual button on the coil can be turned to "1" position by the "0" bit during normal operation, so that the valve is opened. (3) solenoid valve stuck. Solenoid valve sleeve and valve spool with a very small gap (less than 0.008mm), are generally a single assembly, when mechanical impurities into or too little oil, it is easy to get stuck. Approach can be used steel wire from the hole into the head, make it bounce. The fundamental solution is to remove the solenoid valve, remove the valve plug and spool sleeve, with CCI4 cleaning, making the spool movement in the valve sleeve flexibility. Disassembly should pay attention to the assembly sequence and the location of external wiring in order to reassemble and wiring properly, but also check the oil mist hole is blocked, the lubricating oil is sufficient. (4) leaks. Leakage will result in insufficient air pressure, making it difficult to open and close the forced valve due to damaged gaskets or slide valve wear caused by several cavity blow-by gas. In dealing with switching system solenoid valve failure, should choose the appropriate time, and so on when the solenoid valve is in power loss processing, if not within a switching gap processing, the switching system can be suspended, calmly deal with.
