400mm Stroke Adjustable Electric Chain Window Opener Smart Homw Window Driver Building Automatic Skylight Motor

The machine used to open and close windows is called a "window opener" or "window opener". It is generally referred to as a "window opener" abroad, while in China it is mostly called a "window opener". It is currently a new technology product in the domestic construction industry, and "smart electric windows" are the latest development in the modern window industry.

1. High rise windows, windows installed at high or far positions that cannot be reached by human labor alone.
2. The window is too heavy, making it difficult to open or close, and the manual switch is inconvenient to use.
3. Fire smoke exhaust windows with fire linkage ventilation requirements on the floor.
4. There are meteorological requirements for opening/closing windows, such as windows that need to be automatically closed when it rains in the warehouse.
5. Requirements for constant temperature indoors, such as windows in vegetable or flower greenhouses.
6. There are requirements for indoor temperature, and windows will automatically open when the temperature is too high, such as windows in communication rooms.
7. Strict requirements for indoor air index are required, and timely and scheduled ventilation and air exchange are required.
8. Suitable brightness is required indoors, and the angle of the louvers needs to be adjusted to achieve this.
9. Windows require strict sealing force for closure, such as the rain proof sunroof which needs to be tightly closed.
10. Other special occasions, such as chemical, dust and other factory workshops, require timely ventilation.
11. Green, intelligent, and energy-saving modern high-rise buildings, such as curtain walls and windows.
12. Building automation control, smart home control, etc.
Rack and pinion electric window opener
It is driven by a straight rack (with a cross-section of 12 * 12mm).
Small chain electric window opener
It is driven by a double-layer small chain (with a cross-section of 13 * 12mm).
Large chain electric window opener
It is driven by a double-layer larger chain (cross-section 17 * 16mm).
Screw type electric window opener
It is driven by a cylindrical straight rod.
type
1) If it is a skylight: then the first choice is to use a rack and pinion type or a push rod type electric window opener (window opener). This type of method is mainly most suitable for vertical force, without the possibility of bending, and has strong resistance to wind and rain, while the thrust is generally very large.
2) If it is a sliding window: sliding arm or sliding electric window openers (window openers) should be selected. This type of method is more suitable for running in a straight line, and when closing the window, the sealing of the window sash is good.
3) If it's a louver: then choose a small rack and pinion or push rod electric window opener (window opener).
4) If it is an upper/lower/suspended window: choose single chain, double chain, rack and push rod types. For windows with appearance requirements, choose chain type (or for larger windows, choose double chain). For windows with smoke exhaust angle requirements, choose (double push rod type with synchronizer) or double rack type window openers.
5) If the window you are designing is too wide or heavy: if the window is too wide (over 1.5 meters wide) or requires a large push/pull force (over 450N) when opening/closing the window, you will consider using a double push electric window opener (window opener). Double push includes rack and pinion double push and screw double push, which means that a machine can simultaneously produce two racks or two chains to push and pull the same large window, ensuring the stability of the window opening and the sealing degree when closing.
Travel or angle
Opening stroke: Convert the required opening angle into the straight-line distance of the window (according to the cosine theorem), only for daily ventilation. The opening angle should generally not exceed 30 degrees (the opening angle depends on the height of the window), and the window stroke is generally 300-400mm for heights within 1 meter; But there are fire protection requirements, and when the fire signal is linked, the maximum angle for opening the window is generally 70 degrees.
Pushing and pulling force
Generally between 200N and 1000N, a simple calculation of push and pull force F=1/2 (self weight of window sash) * (maximum opening stroke/window height). The power of the smallest window opener (window opener) is 200N, which is generally used for flat open windows with less force.
source
The power supply for the window opening machine includes AC220V, DC24V, etc. Generally, the power supply AC220V is used to connect to smart home systems; Generally, metal curtain walls or windows use a safe voltage DC24V power supply. When there are fire protection requirements, DC24V power supply must be used; And communication facilities use DC48V.

Performance characteristics and selection points
Applicable scope
Chain (hidden/external)
The chain should have a certain strength and stiffness, and should be kept straight and not bent under normal circumstances. Usually, the maximum length of the chain is 200-900mm, the maximum load (tension/thrust) is 200-1200N, and the self-locking force is not less than 2000N.
Used for inward or outward opening windows, can be installed at the top, bottom, or sides.
External mechanical locking point
It can be linked with chain or rod window openers to lock and open windows.
Suitable for locking/unlocking pins on large windows.
Multi point lock (hidden) driver
It can be used in conjunction with chain or rod window openers, and can lock/unlock windows counterclockwise and clockwise. The pushing and pulling force shall not be less than 1500N.
Suitable for locking/unlocking pins on large windows.
Push rod (external) window opener
The push rod should be made of stainless steel with special process treatment, high rigidity and strength, and good waterproofing. Push range: 300-1300mm, thrust: 300-3000N, self-locking force not less than 1500N.
According to different models, it can be used for external windows (which can be installed at the top, bottom, side, and central rotation positions), heavy-duty windows on external sloping roofs and large walls, curtain walls, and glass roofs (which can be installed at the top, bottom, and side positions), as well as high position roof windows.
Internal screw (external) window opener
Adopting an internal screw transmission method, the stroke is generally 150-1200mm, and the pushing and pulling force is 750-2000N.
Suitable for high-level side windows and top windows. Generally, it is installed on vertical window surfaces, but there are also special installation methods for parallel window surfaces.
