1 problem
GK1250-N-centrifuge scraper blade is a wide horizontal discharge centrifuge-filter, it will be medium-size solid-state from its suspension separated, I's a lot of chemical devices used in thisequipment.
Figure 1 for the centrifuge control system schematic. When centrifuge work (whether manual or automatic mode), the first hydraulic system pumps and electric motors host centrifuges into operation, in centrifuges to work manually, through the switch button B5, B6, B7, B8, B9, B10, B11, B12 in the middle of the corresponding control and electromagnetic valve relay network to complete wash, feed, dehydration (1), is expected to wash, dehydration (2), discharge, and other processes. In the automatic mode of work, B5 press the switch, automatic washing centrifuge network feed ? ? dehydration (1) ? ? expected to wash dehydration (2) ? discharge, and periodically the completion of the process, cycle, the process The duration of time from the corresponding relay (T1 ~ T6) control.
In actual use, because of the separation of different materials, different processes required for centrifuges. However, the original control system in automatic mode, can not automatically choose the way of centrifuges needed to process work. In addition, the distribution system by the time the relay time to set the scope is too narrow, the actual use subject to certain restrictions, most of the devices in manual mode, low productivity, poor separation of materials, equipment failure, caused the cost of production toascend
2 improvements
To address these issues, we have the centrifuge control system is improved, the use of single-chip circuit bearing centrifuge Tour temperature detection, protection and alarm limits, and in automatic mode, the process for selection, set the parameters . |
