The electric opening window is a high-tech product integrating mechanical transmission and microelectronics.

Shanghai Dolby Industrial Co., Ltd. is located in No. 589, Quwu Road, Minhang District, Shanghai (China Dream Valley Industrial Park). The geographical position is superior and the traffic is very convenient. The company's predecessor is a professional R&D enterprise that provides OEM and ODM for customers who are engaged in various types of door and window control systems in Europe, America and Southeast Asia. After continuous development and continuous accumulation of its own resources, it has gradually developed into a product development, production, sales, installation and commissioning of its own brand (Dolby), smoke exhaust window, electric window opener and window opener fire linkage intelligent control system. High-tech enterprises with after-sales service.




The appearance of the electric window opener has changed the way of manually opening the window in the past, making the opening of the window into a very simple job.




Therefore, it is a high-tech product integrating mechanical transmission and microelectronics.




The development of the electric window opener has been in the past 20 years. The start electric window opener is only the electric opening of the single window, without any linkage function of the external sensor. With the continuous construction of modern buildings, especially the construction of high-rise and super high-rise buildings, how to automatically open high-altitude windows, making electric window openers more and more important, and some countries have now clearly specified high-altitude glass curtain wall windows. It is necessary to use an electric window opener and an associated moving system when opening.




Electric window opener is divided into its structure




1. Chain type electric window opener (push pull force: 200N-400N, stroke: 150-750mm


2, rack type electric window opener (push pull force: 350N-800N, stroke: 45-1000mm)


3, worm type electric window opener (push pull force: 200N-600N, stroke: 15-1000mm)




According to its operating voltage is divided into: 1, AC 220V / 50Hz 2, DC 24V




The use of electric window opener:




The device of the electric window opener is generally exposed




1, the application occasion




(1) Controlling the indoor temperature. If the temperature is too high, the window will open automatically.




(2) Where indoor air is susceptible to chemical odor, dust, etc.




(3), high-rise windows, which cannot be touched by human resources alone




(4) If there is a fire pleading, the fire window will automatically open or close.




(5), pleading for demand for punctual ventilation




(6) Automatically close the window when there is a climate request




(7), the window is heavier, the manpower is not easy to open




(8), begging for the closing of the window is better, such as the sunroof




(9), occasions with special demands, etc.




2. Calculation formula for the opening stroke and thrust of the window opener




a, open the stroke: S = window height * open the sine of the angle




b. Thrust of skylight or inclined window: F=(W1+W2)/2




F is the thrust required to open the window (unit: N)


W1 is the weight of the window


W2 is the weight of snow




C. Thrust of the upper/lower hanging window: F=W/2*S/H


F is the thrust required to open the window (unit: N)


W is the weight of the window


S is the open stroke (unit: mm)


H is the height of the window (unit: mm)




The company is committed to becoming a professional integrated supplier of comprehensive door and window intelligent solutions. In the process of continuous development, we will work hard to create greater value and support for our customers.
