The\u00a0belt conveyor\u00a0is the main conveying equipment for coking coal. The coal unloading and conveying system of the coking plant has a long conveying distance and a large slope. In order to improve the starting ability of the conveying motor, prevent overload, reduce shock and vibration, and coordinate the drive load distribution, The motor and the reducer are connected by a torque-limiting hydraulic coupling with oil as the transmission medium. Affected by factors such as coal quality and rainy weather, the conveying load of the motor of the unloading system is very unstable during operation, especially when the belt deviates and leaks, jams or blocks the bucket, the load will be instantaneously overloaded, and the torque will be limited. The type hydraulic coupling breaks through the fusible plug instantly, causing the oil to spray out, the speed to drop sharply, and finally the conveying system shuts down. At the same time, the rapid vibration caused by the instantaneous imbalance of the hydraulic coupling can easily cause wear, cracking and distortion of equipment components. In addition, these motors have high energy consumption and low efficiency, and their power consumption accounts for 25% of the total power consumption of the coking plant.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-inner-section elementor-element elementor-element-6aaa00c elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"6aaa00c\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-inner-column elementor-element elementor-element-90d0f16\" data-id=\"90d0f16\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-7088731 elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"7088731\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7ef9d73 elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"7ef9d73\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-6a1f40c elementor-widget elementor-widget-heading\" data-id=\"6a1f40c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Points probl\u00e9matiques :<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0704142 elementor-widget elementor-widget-text-editor\" data-id=\"0704142\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>The motor, hydraulic coupling, brake wheel, and reducer are connected by keys, elastic couplings, and end cap bolts to transmit torque.

there is no mechanical connection between the motor and the reducer, so that the vibration of the conveyor belt drive drum side will not be transmitted to the motor side, and the vibration of the motor side will not be transmitted to the high-speed end of the reducer. At the same time, the amplification effect of vibration in the transmission process is also cut off.<\/p><p>When the coal is blocked and the bucket is overloaded, the magnetic coupler can automatically disconnect the torque transmission of the motor to the load. At this time, the motor runs with no load and the belt stops, thus eliminating the phenomenon of the conveyor belt breaking due to overload.<\/p><p>The peak value of the starting current is reduced by about 20% compared with the previous one, the peak duration of the starting current is shortened by 60%, and the instantaneous tension of the tape is reduced by 30%, thus greatly extending the service life of the tape and the motor. The magnetic coupling is simple in structure, easy to disassemble and assemble, and requires low centering deviation. After replacing the hydraulic coupling, it not only achieves the goal of maintenance-free, but also effectively solves the problem of environmental pollution caused by the leakage of the medium oil in the hydraulic coupling.<\/p><p>From the above analysis, it can be seen that compared with the original hydraulic coupling, the magnetic coupling has the following advantages: maximum allowable eccentricity; allowable pulsating load; transmission of motor output torque through magnetic field, no mechanical connection, which can effectively isolate vibration; Flexible starting, the current is reduced during starting; the speed of the load can be adjusted according to the system operating conditions; maintenance-free and easy to install; conducive to environmental protection.
