BQB24(A)
Mine-used flameproof encoder
Purpose and scope of use Application and range of application
Speed closed-loop control is indispensable in coal mine automation systems.Especially for equipment with high requirements for speed feedback, such as mine overhead passenger devices, hoists, and belt conveyors for both people and goods, speed closed-loop control is adopted to enhance the reliability of the system operation. Therefore, the BQB24(A) mine-used flameproof encoder is indispensable in closed-loop control or speed protection devices. The encoder can be used in conjunction with the electrical control devices of mine overhead passenger devices, mine winches, and belt conveyors, or it can be used alone as a speed measuring device and protection device for winches and belt conveyors.
