Nowadays, the electric rolling shutter doors are widely used. Many warehouses and workshops access the main doors of motor vehicles, and many kinds of car garages in residential buildings still use electric rolling shutter doors. Because of its neat design, perfect function, convenient operation, and manual operation during shutdown, it is widely used. The electric rolling shutter door mainly consists of end plate, roller, rolling shutter motor, transmission chain, slide rail, rolling shutter sheet, electric control box and other components.
Fireproof rolling shutter door is a kind of fire prevention and heat insulation facilities suitable for large openings of buildings. The product plays a certain role in the design and installation. Fire shutter door is widely used in industrial and civil building fire partition area, can effectively prevent the spread of fire, protect the safety of life and property, is an indispensable fire prevention facilities in modern buildings.
From the action of fire to the time when the heat radiation intensity of the back fire surface exceeds the specified value of the critical heat radiation intensity, or when the curtain plate surface is on fire. This period of time is called fire resistance limit, which is used to determine the fire resistance grade of steel fire shutter.
The curtain plate, seat plate, guide rail, lintel and box body shall be made of galvanized steel plate and strip, as well as ordinary carbon structural steel. High quality carbon structural steel or ordinary carbon structural steel, electric welded steel pipe or seamless steel pipe are used for reels. The bearing shall be made of ordinary carbon structural steel or gray cast iron. The thickness of the curtain plate is 1.2-2.0 mm, the thickness of the buried guide rail is 1.5-2.5 mm, and the thickness of the exposed steel plate guide rail is ≥ 3.0 mm. The depth of the curtain plate embedded in the guide rail shall meet the requirements in the table below.
Installation requirements: when the steel fire shutter is installed on the building wall, it should be welded with the embedded parts in the wall or connected with the embedded bolts. It can also be installed with expansion bolts, but its anchoring strength must meet the requirements.
In the process of operation, the operator shall not leave the operation site without authorization. Close attention should be paid to the opening and closing situation and the implementation. No one is allowed to stand or walk under the rolling shutter when opening and closing. In order to prevent travel switch failure, roller shutter stuck, motor blocked and other accidents. Fire compartment and fire partition of steel fire shutter usually do not make frequent use, once the area of fire. The rolling shutter should be put into use effectively, with linkage control and automatic control. The rolling shutter must be carried out according to a set of control instruction program.

The motor is the central address of the whole electric rolling door, and it is also the brain of the whole electric rolling door. It controls the survival of the whole electric rolling door, so the motor equipment and limit debugging are very important in all the electric rolling door equipment programs. If the motor needs to be replaced, the repair should also be very careful. The following Jinan electric roller shutter door installation and maintenance of small series and you introduce some common sense of electric roller shutter door.
The motor of the electric rolling shutter door is connected with the mandrel of the drum by a transmission chain, and the motor anchor is fixed on the sprocket support plate with screws. Before replacing the equipment or motor, the rolling shutter door must be lowered to the lowest end or supported by a bracket. This is due to the following reasons: first, the brake of the rolling shutter door depends on the brake on the motor body; after the motor is cancelled, the rolling shutter door does not brake and slides down actively; second, the transmission chain can be relaxed so that the chain can be removed easily.
Installation and maintenance of Jinan electric rolling shutter door
The process of replacing the motor: mark the motor wiring and then cancel it, loosen the motor anchor screw and take off the drive chain. After all, cancel the motor anchor screw and take out the motor; the order of new motor equipment is opposite, but pay attention to it. After the motor equipment is finished, the circular hand zipper bar on the body should be natural and straight down, and there should be no jamming appearance.
After the replacement of the motor, check the circuit and mechanical organization. There are no obstacles under the rolling shutter door. No traffic is allowed under the door. After admitting, test run and adjust the limit. The limiting organization of rolling shutter door is the device on the motor shell, which is called limiting screw sleeve sliding block type. Before the machine test, loosen the locking screw on the limit organization, and then pull the circular chain by hand to distribute the curtain 1 meter above the ground. First, try the "up", "stop" and "down" buttons to investigate whether the functions of the door lifting, stopping and lowering are flexible and reliable. If normal, the curtain can be raised or lowered to the determined position, and then rotate the limit screw sleeve to adjust the touch to the microswitch roller to hear the noise After the "tick" sound, tighten the locking screw. Repeat the debugging to make the limit reach the best position, and then tighten the locking screw.
Electric roller shutter door in the process is a lot of choice, so more understanding of the industrial knowledge of electric roller shutter door is a good thing, also easy to use as usual.
Installation and maintenance of Jinan electric rolling shutter door
Installation method of electric rolling shutter door (a) reserve ￠ 32mm PVC pipe, from the lower end of the control box to below the ground level, through the wall to the outside, to the approximate position of the track, 0.1-0.15m below the ground level, for the outdoor line of the expansion door to enter the room.
(b) Install the telescopic door, connect the line, and debug the switch control box.
(c) According to the above table, when building the door opening, the inner clearance of the opening shall not be less than 0.75-0.8m, the inner clearance of the height shall not be less than + 0.25m for ordinary doors and + 0.1M for luxury doors; the middle and upper end of the inner side of the end of the door opening shall be provided with a manhole with a width of 0.4m and a height of 0.6m. If possible, the total length of the door opening can be further extended by 0.2-0.3m, so that the manhole can be changed into a small door, It is convenient to repair and maintain the electrical circuit of the telescopic door in the future;
(d) To lead the 220 V power supply to the lower end of the control box, it is better to bring another grounding wire, with the thickness of 1.37, leakage protection device and PVC concealed laying;
(e) Determine the position of the indoor control box, that is, the position of the device to operate the telescopic door switch;
(f) Before laying the track, in addition to leaving a width of about 0.8-0.9 meters, the ground on both sides should be prepared first; after 2-3 days (5-7 days in winter), while laying the track, the civil engineering should cooperate with the ground at the track. During laying the track, the road should not be allowed to pass, so as to avoid bending the track;
