Y filter is to remove a small amount of solid particles in the liquid small equipment, can protect the normal work of the equipment, when the fluid into the filter filter, the impurities are blocked, and the clean filter by the filter outlet, when need to cleaning, as long as the removable filter is removed, reloaded after processing, therefore, the use of maintenance is very convenient.Plastic Filter, also known as decontamination, filter valve, is an indispensable device of conveying medium pipeline system, its role is the mechanical impurities in the filter medium, can on the sewage rust, sand, a small amount of solid particles in the liquid filter to protect the equipment pipe accessories from wear and blockage, can protect the normal work of equipment.
Y Strainer is Y type, one end is the water flow, one end is the precipitation waste, impurities, usually it is installed in the PVC Pressure Reduce Valve,PVC Back Pressure Valve, water level valve, or other equipment inlet, its role is to remove impurities in the water, to protect the normal operation of the valve and equipment, PVC Strainer to be treated water into the body, water impurities deposited in the stainless steel filter, the resulting in pressure difference. Through the differential pressure switch monitoring inlet pressure difference change, when the differential pressure reaches the set value, the electric controller feed hydraulic control valve, drive motor signal, cause the following actions: motor drives the brush rotation, clean the Plastic Strainer, at the same time, the control valve open for discharge, the whole cleaning process only lasts for tens of seconds, when the end of the cleaning, close the Control Valve, motor stop rotation, the system back to its initial state, began to enter the next filtering process. After the equipment is installed, the technicians shall debug, set the filtration time and the cleaning and conversion time. The water to be treated enters the body from the water inlet, and the filter starts to work normally.
Selection principle:
1. Import and export diameter: In principle, the inlet and export diameter of the filter should not be less than the inlet diameter of the matching pump, generally the same with the import pipe diameter.
2. Nominal pressure: determine the pressure level of the filter according to the highest possible pressure in the filter line.
3. Selection of hole number: mainly considering the size of the impurity to be intercepted, and according to the requirements of the medium process. Check the particle size "filter size" below.
4. Quality of filter equipment: the material of the filter is generally the same as the connected process pipe material. For different service conditions, the filter of cast iron, carbon steel, low alloy steel or stainless steel can be considered.
5. Filter resistance loss calculation: for water filter, the pressure loss is 0.52~1.2kpa when the rated flow rate is generally calculated.
