The structure of the quick shutter is not complicated. Generally, you can see the general situation of the product through visual observation, mainly to observe whether the door body is cancelled and closed smoothly. If you do not use the quick door for a long time, in the best routine test, test whether the open and close buttons are normal, and the indication signals of the electrical control box. More detailed maintenance can be divided into converter maintenance, motor maintenance, regular inspection of converter inlet whether there is blockage of foreign matters, monthly cleaning of filter cooling air duct dust. Annual inspection: conductor and insulator are not corroded, if any, they should be wiped with alcohol in time.
Check whether the bolts, screws and plug-ins are loose, and whether there is output and input reactor with short circuit to ground and phase resistance, which should be greater than tens of megaohms under normal conditions. It is very difficult to clean industrial and oil polluted doors. You can scrub them with detergent. It is better not to use strong acid or alkali cleaning solutions. This will not only damage the surface finish, but also damage the metal chips and oxide layer on the surface of the protective film, resulting in the corrosion of metal parts. Especially when some customers clean the sulfuric acid and the wall, you must pay attention not to let the impact of doors and windows. The industrial door motor can be maintained at a proper time.
The reducer shall be lubricated at least every half a year, and other parts shall be inspected regularly and replaced in time. Collision shall be avoided as much as possible during use. For the torsion spring of industrial door, if it is loose after using for a period of time, it should be adjusted and tightened in time, and it needs to be replaced immediately. When opening the industrial door, the strength shall be moderate, and the speed of opening and closing shall be kept as far as possible. A control button is installed beside the fire shutter door. In case of fire, press the button to press the shutter.
The second is the fire linkage control of the fire alarm system. When the fire alarm linkage control system is connected with the fire shutter door controller, the fire shutter door is installed. The fire alarm linkage control system feeds back the signal to the electrical control box of the corresponding part of the fire shutter door to drive the shutter door down. This control mode is the control mode that must be realized, and it is also the standard of fire acceptance. Finally, the mechanical control function located on both sides of the evacuation corridor shall be equipped with shutter opening and closing devices on both sides, and also with mechanical control function, so the fire shutter door shall be equipped with temperature fuse control device.
