1X00416H01 WH5-2FF Slewing Protection Device

In order to protect the equipment, 1X00416H01 WH5-2FF must effectively control its slewing angle within the specified range during sampling, so a slewing protection device is installed. The traditional protection device is installed in the lower part of the rotary body travel switch, this switch is easy to damage, so that the equipment rotary protection failure. In the design of the rotary sampler for Shanxi Tunliu Coking Plant, our company utilizes the high-speed counter function of the programmable counter together with the rotary encoder to effectively realize the measurement of the rotary angle and the rotary protection of the equipment, which improves the reliability and accuracy of the equipment and makes the samples taken by the rotary sampler more representative.

The database of 1X00416H01 WH5-2FF adopts the database visual foxpro6.0 which is consistent with the information management system of the factory, and adopts the video capture card, image splitter and closed-circuit monitoring system. The on-site detecting instrument detects each parameter in the production automatically and continuously, and at the same time feeds the signal back to the on-site plc and the upper computer, and displays it on the monitor of the upper computer; the plc and the upper computer compare the technological parameter set in the program, and automatically regulate the working condition of a certain piece of equipment (starting and stopping) and store the data of the quality of the coal, so as to meet the needs of the production process automatically.

1X00416H01 WH5-2FF is controlled by plc, the principle is to use the encoder connected with the slewing mechanism to send pulses to the plc, the plc counts the pulses at high speed through the received pulse signals, and when the pulses corresponding to the angle of slewing are out of the specified range, the plc controls the slewing hydraulic motor accordingly according to the logic of the configuration to achieve the protection of the equipment. The longitudinal travel of the trolley sends out pulses to the plc directly through the encoder, and the plc counts the received pulse signals at high speed and adjusts them according to the value assigned by the upper computer.
