HGZPG-D automatic sewage electronic cleaning device to electronic cleaning device and automatic sewage filter perfectly together, so that the device while both water treatment and filtration, to a machine with two purposes. Significantly reduce equipment costs, saving installation space, easy operation and management. Works HGZPG-D automatic cleaning sewage electronic instrument with electronic cleaning device and automatic discharge function, which consists of a housing, valve plates, transport handles, cartridges, water movement and hosts, water treatment machine core located within the housing. Filter uses a special structure in which the stainless steel wedge filter. During normal operation, electronic water meter butterfly plate full, after passing through the filter cartridge is out of the treated water from the inside out through valve plate, dirt is left in the cartridge stopped (when connected to the sewage outfall of the valve closed ), when the movement of water through the water by a high-frequency electromagnetic field treatment, also has Anti-fouling, biocide effect. When dirt accumulation rises, will clog the filter, so that the flow area smaller cartridge, causing the pressure difference between the water flow through the cartridge before and after the increase. When the pressure difference reaches allowed value, the valve plate is automatically turned off, the water flowing out from the front in the cartridge after cartridge segment (residue was collected above) from the outside to scour the cartridge automatically open the drain valve, which slag material can be discharged. After discharge, automatically close the drain valve, butterfly valve plate automatically is turned on, the device into normal operation. Features HGZPG sewage electronic automatic cleaning device has both HG-D filter cleaning device and HGZPG characteristics: 1, fully functional: The device has obvious Anti-fouling, biocide, anti-rust corrosion resistance capabilities, can effectively filter the water contamination, a machine can. 2, advanced technology: water processor to run automatically, using intelligent modules complex electric technology, stable performance, powerful, able to automatically adjust the frequency of the output parameters with water, and has a self-diagnostic function. 3, economical and practical: the device is not an area, high performance and low cost, easy to install, easy to operate, the impact on system operation when sewage is small, do not stop sewage. 4, reliable quality: made of imported electronic components, stable performance, transfer shaft mechanical seal, to overcome the shortcomings of traditional fillers leaky seals, special mesh filter made of stainless steel wedge structure. 5, environmental protection and energy saving: less energy consumption equipment, no pollution, no noise, no special care, the economic environment. 6, carefully processed: advanced technology, strict quality assurance system, well-organized, carefully processed to ensure HGZPG-D-type recoil filter electronic water meter with leading levels of quality. Host life of more than 15 years, slave life of more than 20 years. Technical data quality: hardness <1000mg / L (as CaCO3) sterilization rate: ≥ 98% Working pressure: ≤ 1.6MPa pressure loss: ≤ 5.0KPa Operating temperature: ≤ 100 ℃ Size :8-25 mesh strainer / in Anti-fouling rate: ≥ 99% shape parameter interface mode can be different according to user's demand through, on the same side, opposite side and so on. According to user requirements specification filter manufacture of high precision, high accuracy specifications for the 30 to 80 mesh / in. Hangzhou Laurel Environmental Technology Co., Ltd. is a commitment to scientific research, production and sales of water treatment equipment, filtration equipment, water industry professional valve manufacturer. There are self-cleaning water filters exhaust, constant pressure water vacuum degassing unit, water processor family, screw degassing decontamination other four series, covering electronic cleaning device, electronic water processor, constant pressure water unit Vacuum Water pressure exhaust unit, the entire integrated water processor, vacuum degasser, tank water processor, next to the water processor, screw degassing decontamination, air impurities spiral separator and so on. http://www.gvguan.net/shuichuli/24.htm
