LD Series Backwash Industry Water Purifier:
LD series industrial water filter：
Recoil type industrial water filter installed in the water supply pipeline of power plant, chemical industry, printing and dyeing, papermaking and other industries on the pipeline, mainly for the following DN500mm, which can replace the two screen, save money, is the key equipment to achieve the optimization of system management, especially suitable for unattended unattended operation of the hydropower sector.
Technical features：
1. Small size, easy to site layout and installation, maintenance, maintenance, easy adjustment.
Material and structure to maximize the flow of water over the area, effectively reduce the water resistance of the screen, to ensure reliable operation does not occur card, plug, plug phenomenon.
2. The filter adopts 3-6mm stainless steel plate as a whole, the core should be able to withstand the pressure difference of 150 kPa, without deformation, no damage. The utility model has the advantages of long service life, corrosion resistance, no rust, smooth surface and no scaling.
LD type through the differential pressure controller, timing automatic start reducer can be positive and reverse washing, with a clear effect, less water consumption.
Stable operation, clear the impact on the export water pressure is small, fully meet the needs of online operation.
3. The LD function is complete, easy to install, can only access AC380V, 50HZ power source into automatic operation, PLC microcomputer control, can carry out timing, pressure difference, manual control and cleaning, water filter with fault alarm function, and computer network to realize network control.
4. High reliability, long life, low energy consumption.
