Crystal shutter door installation crystal shutter door product performance
Rolling shutter door plays a role in the prevention of theft in life. The crystal shutter door just makes the appearance of the work that users like to accept, because now, as the customer's preference changes, the beautiful rolling shutter door will meet the needs of people nowadays. The most significant value of the crystal shutter door is still a good return to the anti-theft, in addition it is a beautiful decorative effect. Next Xiaobian will introduce crystal shutter door installation and crystal shutter door product performance. Crystal shutter door installation 1, first look at the manual chain is down, in the motor is fixed on the motherboard, the chain is fixed in the wheel and the motor base gear connection (a certain tight) in the remote control box and the motor connection, try to handle the handle is upside down, If there is a black button on the side of the remote control receiving box, it can be dialed to the other party. 2. Use the ruler to check whether the size of the main board and the sub-board is correct. If the shaft is on the side board correctly, pay attention to the shaft first to play a horizontal line, and then use 10 bits to drill the hole 50 cm. 1 must be Straight, then use the 14-female mother to weld on the shaft. Remember to weld perpendicular to the hole in the shaft. Make sure to weld firmly. Align the center of the first piece of the curtain with the hole in the shaft with 10 bits. Punching must be vertical (fastening can also be fast). 3. Put the roller shutter curtain on both sides and seal it with a head to pull it with a rivet (remember to start sealing one block). 4. After the closure, use a rope to turn over the shaft to make a hole in the curtain. Use a rope to hold it. Do not pinch it at one end. Press the handle's ascending key so that the shaft will run to bring the curtain up. The reel will hold the curtain and the shaft. Together (level tightening padding) and lifting the curtain up must be firm. 5, open the mouth of the track adult word. 6. Level the roller shutter curtain and position it on and off the line. The left pulley is the upper limit position and the right is the lower limit position. (Adjust itself according to the needs of the site) 7, matters needing attention a) Standard voltage 220V b) No persons are allowed to stop at the bottom of the rolling shutter c) There must be no obstruction when the shutter door is running down d) When the shutter is lowered, the shutter automatically stops (or press the stop key) e) Automatically stop the shutter when it is rising f) Do not pass people and vehicles during operation g) Minors need to be under guardian guardianship Crystal shutter door product performance 1, full perspective design, display window display effect, preferred for shops in the downtown area 2, using polycarbonate, anti-theft performance is good 3, closed mute effect, prevent wind and rain dust 4, high-strength design, solid aluminum embedded PC door, structural strength, suitable for large-scale facade use 5, the design is simple and elegant, the appearance of noble and elegant 6, can be up and down / left and right installation, suitable for special molding site installation Editor's summary: The performance of the crystal shutter door installation and the crystal shutter door product are introduced here, and we hope to help everyone. If you want to know more about yourself, you can follow the information on this site. Shutter door crystal shutter door installation A ring split at one point and bent into a helical shape. This causes the washer to exert a spring force between the fastener's head and the substrate, which maintains the washer hard against the substrate and the bolt thread hard against the nut or substrate thread, creating more friction and resistance to rotation. Applicable standards are ASME B18.21.1, DIN 127 B.

Spring washers are a left hand helix and allow the thread to be tightened in a right hand direction only, i.e. a clockwise direction. When a left hand turning motion is applied, the raised edge bites into the underside of the bolt or nut and the part that it is bolted to, thus resisting turning. Therefore, spring washers are ineffective on left hand threads and hardened surfaces. Also, they are not to be used in conjunction with a Flat Washer under the spring washer, as this isolates the spring washer from biting into the component that will resist turning.
The use and effectiveness of spring lock washers has been debated, with some publications advising against their use on the grounds that, when tight, the washer is flat against the substrate and gives no more resistance to rotation than a normal washer at the same torque. However, a spring washer will continue to hold the bolt against the substrate and maintain friction when loosened slightly, whereas a plain washer will not.
The benefit of spring lock washers lies in the trapezoidal shape of the washer. When compressed to loads near the proof strength of the bolt, it will twist and flatten. This reduces the spring rate of the bolted joint which allows it to maintain more force under the same vibration levels. This prevents loosening.
