1. Determine the number of working strokes and the working speed range. After determining the number of working strokes and the speed range, select the appropriate model and specifications based on the site conditions to meet construction requirements.
2. Select the transmission method. Since electric rack and pinion window openers have three transmission methods-gear drive, chain drive, and belt drive-it is crucial to identify the correct transmission method and treat them accordingly to achieve the best cost-performance ratio.
(1) Chain drive models are favored by many users due to their simple structure and low cost.
(2) Gear drive models are often rejected by some mid-to-high-end users due to their higher cost and more complicated maintenance.
(3) Belt drive models are one of the mainstream products on the market due to their low noise and long service life.
(4) For special applications, a variable frequency drive can be added to meet different needs.
