Supply shutter doors explosion-proof motor explosion-proof explosion-proof switch. Explosion-proof motor. Strong state industrial doors

YB2 explosion-proof series rolling door opener is the introduction of the latest technology, designed for explosion-proof areas requiring explosion-proof requirements shutter doors, such as petroleum, chemical plants, textile well-designed products. The products in strict accordance with the requirements of GB3836.1-2000 "for explosive gas atmospheres Electrical Equipment Part I: General requirements" and GB-3836.2-2000 "for explosive gas atmospheres - the second part of the electrical equipment: flameproof" d "," the developed into flameproof, Ex-mark for Exd I BT4 Exd II AT4, Exd II BT4 explosion-proof roll shutter door motor. Shutter doors of the explosion-proof motor with explosion-proof performance, limit the precise braking power, convenient adjustment function. Second, the product model and name YB2-600 YB: explosion-proof J: rolling door machine 600: machine hoists 600kg three, use the scope and conditions of use applicable to common flammable gas, steam levels, temperature levels, see Table 12, ambient air temperature with the seasons change, but not more than 40 ° C (factory) and as low as -15 ° C ambient air. 3, the altitude does not exceed 1000m. 4, the maximum relative humidity of the ambient air does not exceed 95%, while the average monthly minimum temperature not higher than 25 ° C (factory). 5, rated voltage of 380V. 6, rated frequency 50Hz. 7, protection class IP55. 8 Ex-mark Exd II BT4 9, brake power provided by the motor terminal box of the rectifier; voltage input is AC380V, DC170V output. Features beautiful shape, compact structure, strong horsepower; 2, low noise, low vibration, low power consumption, long life; 3, light weight, small size, easy to install, reliable performance; 4, can be equipped with a power reserve device, the power outage is still normal use. Can be equipped with self-built networks or on the Internet can be remotely pretentious monitor the operation of the monitoring shutter doors. (Distribution) 6, a power outage can also be manually operated door opening and closing five Note To structure and working principle proof shutter door Ex shutter Opener mainly by the reducer, explosion-proof motors, brake clutch and limit other parts. Reducer part is made of aluminum alloy shell, solid and lightweight; clutch electromagnetic brake, when access to power brakes, brakes began to work due to the electromagnetic suction, the electromagnet attracts the armature and compression spring brake disc armature end cover torn off, the motor will start running. The electromagnet lost when power is turned off electromagnetic force, the spring pushes the armature compression brake disc, immediately stop work in the role of friction torque motor; explosion-proof motor selection Exd II BT4 YB2-801-4 the flameproof motor (also can be customized according to customer needs Exd I BT4 mine explosion-proof motor); electronic positioning stopper, shutter doors do not have height requirements, the theoretical limit range is no ceiling limit.
