P-type backwash filters /strainers----water pretreatment filters ---coarse filters

Filtration fitness: 2-6mm Flow capcity: As your need.

1 Function and Uses

P-backwashing filter applied to a variety of water supply systems, process water systems and industrial cooling water systems, especially a 24-hour continuous operation of the non-stop system that can filter out a variety of mechanical impurities in the water to ensure the system safe and reliable operation of equipment.

A wide range of filtration precision: Stainless steel punching boards d = 2.0-6.0mm

Structure and working principle of P-backwashing filter P-backwashing filte is made y by the high-quality carbon steel cylinder, stainless steel punching board( 2-6 mm punching hole), valves and flow-driven composition of the sewage plant. When the filters work, flow-driven valve is turned on, water flows from the entrance to the filter, through the filter, to the exit When the filter needs of sewage, close the valve flow-oriented, open sewage valve, water flow through the filter first half of the filter, part of the water flow into the system by exports, the other part of the water from the filter into the second half of the medial lateral, after sewage outfall discharges played on the filter's backwash effects. Thus the entire washing process can still be running, with no downtime.

To open the valve body flow-oriented sub-two kinds of manual and electric, manual opening mechanism handles used to open the small size, large size (DN500 and above) can be used when the user needs to manually open the worm gear mechanism; Electrical opening mechanism sub-timing control and pressure control of in two ways, using timer control, when equipped with micro-computer controlled timer switch, can set the time requirements to achieve self-cleaning sewage; Use of differential pressure control, equipped with differential pressure controller, when the inlet and outlet differential pressure reaches the set value (usually taken as 0.05MPa), it can automatically clean the sewage. At this point the sewage outfall installation of electric valves, flow-driven valve and electric valve to achieve linkage sewage.

MODEL:

From the installation vertical or horizontal. There are two kinds of manual and electric, manual operation, itis required anti-flushing operation manual, that is, the time required by the manual switching valve and the sewage flow direction valve to complete the sewage. Electric operation is divided into two kinds of timing control and pressure control, need to indicate when ordering.

Conventional nominal pressure 1.0 MPa, other pressure levels( 0.25Mpa, 6Mpa and so on ) may be ordered according to user requirements, orders must be indicated on the nominal pressure in the contract.
