EMG thruster EB800-60

detailed description:

EMG thruster EB800-60The idle time refers to the time elapsed from the moment the power is cut off and the brake is applied until the brake shoe comes into contact with the brake disc, mainly reflected in the braking devices of mine hoists and other automatic control systems. Excessive idle time can cause braking lag and potentially lead to safety accidents. Therefore, it is also an important parameter reflecting the performance of braking. Currently, the detection of idle time mostly uses the electric stopwatch method, which has high detection accuracy. However, due to its relatively high cost, it is rarely used in actual testing. In order to accurately detect the idle time at a lower cost, researchers have studied and designed various methods for detecting the idle time of disc brakes. A detection system consisting of a test circuit board, signal processing module, acquisition card, and computer was designed using the working principle of relays, and the detection system was tested using the Labview program module; The idle time has been detected, and the system consists of intelligent sensors, data acquisition devices, industrial control computers, etc. in hardware, and a parameter display interface developed through Kingview in software; During the actual operation of the hoist, the idle time of the disc brake was calculated using a timer.

EMG thruster EB800-60Disc brakes decelerate the brake disc by applying braking force, and braking deceleration is the most direct and objective factor that characterizes braking performance. Therefore, detecting braking deceleration helps to analyze the state of braking performance. At present, the most common method for detecting braking deceleration is to directly collect the rotational speed through photoelectric encoders or other sensors, and then analyze and display it on the upper computer. Measure the operating speed of the hoist using a rotary encoder during the braking process, determine the initial braking speed and time based on the speed curve, and then calculate the braking deceleration; Ge Pinghua et al. used SZGB11 photoelectric sensors and attached black and white line drawings on the circumference of the spindle. During braking, they obtained pulses proportional to the speed and black and white lines, and then calculated the speed and deceleration.
