Works ??? JRDZFD type differential pressure electronic water meter with an electronic water treatment and filtration, self-cleaning filter function, mainly by housing, water movement, automatic control devices, cartridges and other components. Work, after the water into the device first by water movement, in the role of high-frequency alternating electromagnetic field, the water molecules can be activated carrier can prevent scale formation, and can destroy the old scale, biocide, the treated water then flow through the cartridge, where the dirt is trapped down the barrel, when the dirt accumulation rises, can clog the filter, so that fewer and fewer cartridge circulation area, resulting in a pressure difference between the front and rear of the water flowing through the cartridge be greater. When the pressure difference reaches the upper limit value controller allows automatic control signal output device, electric pilot valves, electric water valve is closed, and open sewage electric butterfly. After discharge filter dirt circulation area back to normal, ide reduce the pressure difference before and after the water flow through the cartridge. When the pressure difference between the value of the lower reaches controller allows automatic control means responsive to the output signal, turn on the electric pilot valve, the valve, close the drain valve electric, sewage ends. Technical parameters of water quality: hardness <700mg / L sterilization rate: ≥94% working pressure ≤1.6MPa set pressure range: 0-69KPa temperature: ≤98 ℃ cleaning time: 15-40s fouling rate: ≥99 % resistance loss: 2.0-6.0KPa filter specifications: Features: JRDZFD type differential pressure filter electronic processing device also has JRDZ JRFGL water meter and filter characteristics: 1, full-featured: equipment has obvious Anti-fouling, sterilization algae, rust and corrosion inhibiting function, can effectively filter the water and dirt, a machine can. 2, automatic operation: Water foliation host automatic operation, can automatically adjust the frequency of the output parameters; after the first set pressure parameters, you can automatically detect the pressure difference, self-cleaning filters, automatic sewage, truly unattended . 3, accurate and reliable: using intelligent template complex electric field of water treatment technology, stable performance, powerful; pressure controller imported brands, with accurate measurement, control and reliable advantages, eliminate errors due to measurement and control devices do not work or cause downtime phenomenon. 4, economical and practical; small device footprint, high performance and low cost, easy to install, easy to operate. 5, excellent selection: selection of imported pressure controllers and electronic devices, reliable quality; mesh stainless steel drum to strengthen the structure, difficult to damage. 6, multiple self-protection: The controller has a self-diagnostic function, the filtration system operating time limit protection is provided when the device is faulty, causing sewage filter has been in a clear state, the maximum continuous cleaning time is controlled within 5 minutes, and Call the police. 7, green energy: energy consumption and less equipment, no pollution, no noise, no special care, and economic environment. 8, carefully processed: advanced technology, strict quality assurance system, well-organized, well-processing, ensure JRDZFD-automatic differential filter electronic water meter with a domestic leading level of quality and selection, service life more than 15 years.
