1、Use： 
Recoil type industrial water filter installed in the pipeline for water power station, chemical industry, printing and dyeing, papermaking and other industries, main pipeline for the following Dg500mm, which can replace the two screen, save money, is the key equipment to achieve the system optimization management, especially suitable for unattended less people on duty of the hydropower sector. The water filter is a kind of equipment with automatic filter, sewage, sewage it is to eliminate particles and suspended matter in water, the necessary device of. LD type as the technical water supply automatic filtering full-automatic water filter is a genus of rotary type, which is the executing agency and the automatic control mechanism, including the speed reducing device, filter the water body, the electric drain valve, differential pressure controller and electrical control box. The water filter cleaning sewage process can be carried out in an uninterrupted water supply under normal。

2、work principle:

Work process: water filter into the piping system, water enters the water filter is composed of a lower water inlet, filter debris after the water flows out from the water outlet, when the water goes through the network core, because the volume is greater than the net holes and slits, trapped in the network core, when accumulated to a certain number, which causes the water inlet and the water outlet there is a certain pressure difference. When the filter inlet pressure meter and the outlet pressure gauge pressure difference increases to a specified value (filter precision of different diameters with different pressure difference, usually 0.15Mpa), open the drain valve to work, the flow to the attached to the network core inside wall surface impurities dirt back flush, the attachment filter to be discharged, the pressure difference inside and outside the closed the drain valve to return to normal, thus completing the filter and drainage work process.

3、advantages or features;

The small size of the appearance, convenient field arrangement and installation, repair, maintenance, convenient adjustment.

Increase the flow area flow of the plate material and structure to maximize, effectively reduce the filter water resistance, to ensure reliable operation without card, plug, plug phenomenon, greatly prolong the service life of the filter.

The filter uses 3-6mm stainless steel plate stamping, net core should be differential pressure can withstand 150 kopi, not deformation, not broken. Has the characteristics of long service life, corrosion resistance, no rust, surface smooth, no scaling.

CLD type automatic type by differential pressure controller, automatic timing starting speed reducer can be positive reversal, has strong decontamination effect, sewage water consumption.

Stable operation, cleaning of outlet pressure effects of small, fully meet the needs of online operation.

CLDtype automatic type complete function, convenient installation, only access to the AC380V power source, can be 50HZ in the automatic mode, the PLC microcomputer control, can carry out timing, pressure difference control, manual cleaning, water filter with fault alarm function, can realize network control network and computer.

High reliability, long life, low energy consumption
