General guidelines for electric window drives
1. Driving force (including external thrust and shortening force)
This policy is directly related to the weight of the driven window. The unit is generally Newton (N). The driving force of the single-type electric window opener is generally 200N-1000N.
2, flexible stroke
Directly affects the angle of the window opening. (Note: the larger the stroke of the chain window opener, the smaller the driving force)
3, travel speed
Generally, the unit is in mm/s. Since the speed of the electric window opener should not be too large, the existing policy is ≤40mm/s, and the general speed is not adjustable.
4, operating frequency
Refers to the number of repeated operations in a unit of time, this policy directly affects the operating life of the electric window opener, the general electric window opener is not suitable for repeated occasions to open the window
5, the operating voltage
In general, the AC220V voltage operation method can be used. When it is used in conjunction with the fire protection system and in special occasions for safety appliances, the DC24V voltage operation method is selected.
6, operating current
This policy can be used to select the power supply of the large electric window opener linkage system. In general, the electric window opener in the intelligent building can be used up to several hundred at a time.
Dolby electric window drives are primarily used in these 12 local areas:
1. High-level windows: the windows are oriented at a higher or too far distance, and the windows are not accessible by humans alone.
2, the window is too heavy, open or close the effort, manual switch is not convenient to use
3. Fire-fighting smoke exhaust windows with fire-fighting linkage ventilation requirements on the floor
4, there are climate open / close window requirements, for example: windows that need to be automatically closed when it rains
5. For indoors with constant temperature requirements, such as: windows for vegetables or flower greenhouses
6, the room temperature is required, the temperature is too high, automatically open the window,
7. For indoors with strict air index requirements, timely punctual ventilation
8, the indoor demand is more suitable for the brightness, need to adjust the angle of the blinds to complete
9, the window demand is more severe to close the sealing force, such as the sunroof rain protection needs to be closed tighter
10, other special occasions, such as chemical, dust and other factory workshops, need timely ventilation
11. Green, intelligent and energy-saving modern high-rise buildings, such as curtain wall windows, etc.
12, building automation, smart home control, etc.
Electric window openers are electric machines used to open and close windows, so they are called "electric window openers" or "electric window openers", referred to as "window openers" or "window openers". Now it is a high-tech product for the domestic construction profession, and the “smart electric window” is the latest development of the modern window profession.
