For the selection of the IP protection level requirements of the smoke control fan control box, refer to the IEC classification of the protection level, and the anti-smoke fan control box is reasonably selected according to the actual operating environment of the cabinet cabinet. IP54's protection level can basically meet the dustproof and waterproof requirements of most outdoor environments. The reasonable choice of the IP protection level of the control box cabinet body of the smoke control fan should avoid the IP protection level is too low, which can not play an effective protective role; the IP protection level is too high, resulting in the cost of the whole box.
Install the anti-smoke fan control box indoors. If there is no waterproof requirement, the IP protection level can generally choose IP30. If the environment is wet, the waterproof requirement can be IP54 or IP55 to prevent foreign objects, dust and water from entering the cabinet cabinet. Affect the normal operation of electrical components.
The two components of the IP protection level, the first number represents the level of electrical dust prevention and prevention of foreign object erosion. The higher the number, the higher the protection level. The foreign objects contain tools, and the fingers of the human body cannot be touched. Partly to avoid the risk of electric shock.
The fire control cabinet produced by Shenzhen Yuxiang Equipment, the national is the relevant requirements for the IP protection level of the fire pump control cabinet: when the fire pump control cabinet is set in an independent control room, its protection level should not be lower than IP30; When the fire pump is set in the same space, its protection level should not be lower than IP55. Therefore, Shenzhen Yuxiang Equipment recommends that customers choose the IP protection level of the corresponding products according to the actual situation when selecting the fire control equipment products, and also choose the regular manufacturers with complete certificates to ensure product quality and after-sales service.
Rotary drilling machine is a kind of construction machinery suitable for hole forming in foundation engineering.
It is mainly suitable for the construction of sandy soil, viscous soil, silty soil and other soil layers, and is widely used in the construction of cast-in-place pile, continuous wall, foundation reinforcement and other foundation foundation
The rated power is generally 125~450kW, the power output torque is 120~400kN·m, 0 large hole forming diameter can reach 1.5~4m, 0 large hole forming depth is 60~90m, can meet the requirements of all kinds of large foundation construction.
1. High drilling efficiency reduces the activity cost;
2. Simple structure, easy to disassemble and maintain;
3. More humanized operation
4. The overall weight is light, and it is a split structure, which is convenient for relocation and transportation
