Part 1: Industrial Water Filter Applications
Installed on water supply pipelines in power stations, chemical industries, dyeing and printing, papermaking, and various other industries, mainly suitable for pipelines with a diameter of 500mm or less, and possesses the following advantages:
1: Compact in size, easy for on-site arrangement and installation. Electric water filter, industrial water filter
2: The water filter's inlet and outlet structure is a top and bottom split design, which not only prevents direct water pressure impact on the filter mesh but also alters the traditional filter mesh's filtering process where debris is far from the drain outlet. This often requires cleaning each filter chamber individually during drainage, which can lead to jamming.
3: Mesh Material and Structure - Increases the flow area for water, effectively reducing the resistance of the filter mesh, ensuring reliable operation without jamming, clogging, or blocking, significantly extending the lifespan of the filter.
Filter screen is made of 2-8mm stainless steel plate, fully stamp formed. The core can withstand a differential pressure of 150 kPa without deformation or damage. It features a long service life, corrosion resistance, non-rusting, smooth surface, and no scaling.
5: Electric device operates at a slow speed with smooth running, capable of forward and reverse operations via a differential pressure controller. The timer-activated automatic start of the decelerator allows for forward and reverse rinsing, featuring strong cleaning effect and low water consumption for waste discharge.
Section II: Structure
Filter pumps are available in manual and electric types, mainly consisting of:
1. Turntable shaft assembly 2. Inlet and outlet water ports 3. Bracket housing 4. Mesh core system 5. Electric reducer (including electrical cabinet) 6. Drainage outlet, etc., components. Water filter, industrial water filter, pipeline filter
Section 3: Working Principle
Manual Operation Process: After the filter is connected to the pipeline system, water enters the filter through the lower inlet. As impurities in the water pass through the core, they are retained on the core due to their larger size than the core holes. When accumulated to a certain quantity, it creates a pressure difference between the inlet and outlet. (The pressure difference varies with the filter mesh precision diameter, usually 0.15 Mpa.) Manually open the drain valve to start draining. Rotate the handle, either clockwise or counterclockwise, turning one step every 10-30 seconds. The handle is fixed at each indentation. The water reverses to flush the impurities adhering to the inner wall surface of the core. Continue until a full rotation is completed, then close the drain valve to finish manual draining.
If the customer selects an automatic water filter, options include differential pressure drainage and timed drainage.
1. Differential Pressure Backflushing: When impurities accumulate to a certain quantity, utilize the differential pressure signal between the cooling water's inlet and outlet pipes to backflush and discharge. This is achieved by connecting the electric junction pressure gauge to control signals, which in turn activates the electric backflush valve. The electric reducer operates at a speed of 3-6 rotations per minute, reversing the flow of water to flush away impurities adhering to the inner wall surface of the mesh core. The flushed-out waste is then discharged into the cooling water outlet pipe via the backflushing pipeline and valve.
2. Users can set the effluent timing as needed, ranging from 0 to 9999 hours for the cleaning and effluent schedule. Generally, effluent is set to occur every 12 hours, and the timing can be adjusted according to the water quality of the power plant. Reverse the electric reducer to open the effluent valve, and then proceed with the reverse flushing and effluent process.
