Related Q&A FAQs:
1. What does the explosion-proof rating Ex d I/Ex tD A21 IP65 represent?
The explosion-proof level Ex d I indicates that the equipment is suitable for the explosion-proof environment of mines (such as coal mines) and can prevent explosive gases from entering the interior of the equipment. Ex tD A21 indicates that the equipment also has explosion-proof protection in dusty environments, which can prevent dust accumulation and explosion. The IP65 protection level indicates that the device is dustproof and waterproof, and can withstand water spray in harsh environments.
2. How to choose the appropriate working voltage?
Select the appropriate operating voltage based on the power configuration of the conveyor belt system. PP-K3-MT2 supports 24VDC, 110VAC, and 220VAC. 24VDC is suitable for low voltage control systems, while 110VAC and 220VAC are suitable for standard power systems. When choosing, it should be ensured that it is compatible with the existing power system and determined based on the power requirements of the equipment.
3. How to ensure long-term stable operation of equipment in extreme environments?
The design of PP-K3-MT2 has taken into account the usage requirements in extreme environments, using wear-resistant and corrosion-resistant materials, and has explosion-proof and high protection levels. However, when used in extreme environments, it is recommended to regularly maintain and inspect the equipment to ensure proper functionality, and adjust device settings according to environmental conditions.
