AN EFFICIENT APPROACH OF MECHANICAL PUMP SEALING FILTER SYSTEM USING PLC

Electronics and Electronics Engineering

The project gives out the testing and fabrication of working mechanical pump sealing filter system (HYDAC water filter system) along with its purification which had been used to prevent the overheating of Mechanical Pump and for the production of Paper in Industry. Mechanical Pump Sealing Filter System consists of Pump associated with the Shaft, Sealing, Bearings and the Carbon brush. This Pump is mainly used to transfer the water from one place to another. Water requirement and consumption are more in the Paper Industries, so the Pump continuously in working state. To reduce the heat, cooling water is circulated throughout the process into the sealing. This cooling water must be free from fine particles, sands and dust. So, the water should be filtered. The HYDAC Filter is used to filter the water. HYDAC Filter system has automatic Back-Flushing process. This means it automatically cleans the dust particles settled in the filter. To control the all process, the control board circuit and the programs are used. According to the program the water filtered and given to the Pump Sealing to reduce the heating. Because of high cost and low life time we are replacing the circuit board by using the PLC. The PLC program is simple to execute and troubleshooting is also very easy. There are four valves which are controlled by the Program. At a time, the control valve begins a backwash to clean the medium of collected particles and to emigrate the bed and rejects channel that has formed. The backwash is done by the water is sending down to the riser tube from which it enters the filter tank at the bottom. The force of water pulls to media bed, swirling and tossing the granular medium. The water flows to the control valve from the filter tank, which routes through the filter drain line, the particles which are present in the bed are washed to drain. For several minutes the backwash intense rinsing and tossing of the medium.
