Chengdu eight Peng glass hardware accessories wholesale and retail vendors slotted automatic doors for indoor fan or fan lightweight double folding doors; mute design, quiet operation, durable, hanging rail with high-quality aviation alloy material, with features from the dust. Fully upgraded, quality assurance Products ?? tensioner: hanging on a belt tensioner module, the module is equipped with a mechanism to adjust the belt tension ?? only peer: This device is made of high quality steel, can restrict the freedom door The net open width, rubber stopper ligands may well slow the impact force ?? belt: using gear belts, small scalability, high transfer efficiency, there is little need for further adjustments as a result of expansion and contraction. ?? Hanger Group: This module is equipped on the door wheels, can be moved on the aluminum rail of the engine case, the maximum weight of 150 kg can carry large doors. ?? Controller: accept human detection signals from the sensors, horse-driven motors, control the movement of the door, can be applied to 220-volt power supply, do not have another transformer ?? motor and transmission device: high efficiency, compact, powerful efficacy DC brushless motor. Transmission gear box with high efficiency, low noise helical gear, and drive belt module. ?? Aluminum beams: high hardness made of aluminum, can be easily cut off, the opening of various widths can be field adjusted, with the optimum size for installation. Features ?? 1, new technology and equipment motors, motor structure to improve and optimize the deceleration devices designed to reduce noise returned 2 into one o'clock, optimization controller program, with the new motor design, run more smoothly, more fluid ?? 3,120 High-strength polyurethane wheels, lower flow friction noise ?? 4,150 nylon pulley, extended service life ??? 5, using a newly developed sensor product specifications 1, 120kg or less (single open), door width (600- 1250mm), opening speed 14-41cm / s, closing speed 10-40cm / sec, the opening hours of 0-9 seconds, the ambient temperature from -20 to 50 degrees Celsius, the normal voltage 200-250V 50 / 60Hz 2, 120kg less * 2 ( double open), door width (600-1250mm), opening speed 14-40cm / s, closing speed 10-38cm / sec, the opening hours of 0-9 seconds, the ambient temperature from -20 to 50 degrees Celsius, the normal voltage 200-250V 50 / 60Hz? 3,150kg or less (single open), door width (600-1250mm), opening speed 14-41cm / s, closing speed 10-39cm / sec, the opening hours of 0-9 seconds, ambient temperature -20 to 50 degrees Celsius normal voltage 200-250V 50 / 60Hz 4,150kg or less * 2 (double open), door width (600-1250mm), opening speed 14-34cm / s, closing speed 10-34cm / s, opening hours 0-9 second, ambient temperature -20 to 50 degrees Celsius, the normal voltage 200-250V 50 / 60Hz another monogamous: fingerprint lock, fingerprint (visual), password disk, wireless password disk
