The Points for Attention in Purchasing Electric Shutter Door The rolling shutter door (also known as the rolling shutter) which is common in life is constructed by connecting the door panel as a multi-joint movable module in series, running in the fixed rails on both sides, and pulling the roller blind through the motor driving reel above the door body. Rolling shutters are widely used in shops, banks, hospitals, garages, dock warehouses, factory buildings and other places. The principle of purchasing electric roller shutters is probably the following four points: 1. Selection of profiles for electric rolling shutters The existing rolling shutter profiles on the market are roughly divided into aluminum and aluminum-magnesium alloys. For the overall quality requirements of the rolling shutters, the rolling shutters of aluminum-magnesium alloys can be selected, which has great advantages in toughness. If the overall requirements are not high, you can choose recycled aluminum profiles, the price will be lower. 2, the choice of pulleys for electric rolling doors The pulley of the electric rolling door is composed of two sets of upper and lower parts. The structure of the high-quality upper pulley is complicated, and two pulleys are fixed inside the bearing and the aluminum part. The high-quality electric rolling door must have a self-weight device in the sliding module, and there is not much vibration and abnormal noise when running the sliding.

The replacement method of trackless retractable door pulley The main feature of the electric trackless retractable door is that it will not be damaged on the original ground, and the original site can be installed to maintain the integrity of the original site. However, after years of use of the telescopic movement, the pulley of the retractable door is prone to wear and tear, resulting in the rear door body not moving normally. In this case, the damaged pulley should be replaced, and the retractable door should be kept in normal operation to avoid occurrence. accident. When replacing the pulley, try to choose a professional or the original installed manufacturer, so that the replacement is more careful, you can also see if there are other problems. If the retractable door is still under warranty, you can find the manufacturer to reinstall or send the wheel accessories. . However, finding someone to install on site may cost a lot, sometimes it may be higher than the cost of the wheel. If the factory is shipped and installed, the cost will be low. This situation applies to the case of only a few bad wheels. The wheels of the stainless steel trackless retractable d

How to repair the glass sliding door when it was blown out by the wind?

What should I do if the roller shutter door is broken? Rolling shutters are used in many places, such as garage doors, shop doors, warehouse doors, etc., mainly because the shutter doors are simple to install and easy to operate, so they are so widely used. However, as long as it is a product that will be used frequently, there will always be some parts that will be worn out or even directly broken. Let's talk about several common fault conditions of the rolling door: Rolling shutters are broken and can't be rolled up. This is a problem that many shop owners often encounter. This volume is almost the same as the problem of not being able to pull down. It is mainly caused by manual shuttering, because manpower intervenes, sometimes The ability to use the gas is so large that some parts are damaged, which leads to such a situation. Usually, it cannot be rolled up because the door curtain on the rolling door is stuck in the groove of the guide rail, and maybe even the door piece of the whole curtain is affected. This is caused by force deformation. In this case, it is necessary to find the damaged curtain. If it is just an ordinary card owner, it is flat. If it is deformed, it needs to be replaced immediately to avoid damage to the entire door due to subsequent failure.
