Second filter automatic secondary filter electric secondary filter

Second filter system is then purified water contamination, keeping the condenser water chamber often in a clean state, to ensure the normal operation of plastic balls, rubber balls to improve the recovery rate indispensable means. Our company is the production of electric power auxiliary equipment sentinel plants, through the past few years continue to solicit the views of the majority of users and the secondary filter of repeated trial and continue to improve, so the second filter structure and performance more perfect, and is widely used 6MW 300MW thermal power generating units to open-cycle cooling water system, the praise of new and old customers. Second, fixed and rotary two secondary filter Features Currently the power plant condenser circulating water system is more commonly used, through years of operation proved the existence of the following main problems: 1, fixed characteristics : fixed core network can not rotate, clean up dirt poor, mesh easy to plug, cleaning down to wait. 2, Rotary features: network core rotation, cleaning negative backlash against the strainer strong decontamination capacity than fixed, but the peak season when the goods more serious water pollution, and water containing plastic film. When weeds and other sticky dirt overlooking the strong force, the cleaning effect is still not ideal, such as the case when the sewage chamber blade wear serious, clean-up effect is even worse, there is a big drawback of the structure: (1) Driver Network core A pair of size gear perennial water containing sediment and other impurities in operation, easy to wear and corrosion, seriously affecting the safe and economical operation of the unit. (2) The drive control system is more complex, generally by controlling the solenoid valves, pumps, tanks, fuel tanks, motor oil, oil control box and other components, run among the most prone to oil spills, control failure phenomenon. (3) the maintenance, repair workload. The presence of the secondary filter for the shortcomings, the company through research and repeated trial system is designed to power rotary kick secondary filter, is currently the best performance of the second filter, which has the following characteristics: 1, core network drive gear and circulating water cut off, the lubrication system is fully enclosed to open the form, the gear is no longer water, sediment and other impurities to wear and erosion. 2, to eliminate the transmission of complex fault prone shortcomings exist in the old second filter, fixed line safe, reliable, easy repair and maintenance. Third, the structure and working principle of rotary electric kick secondary filter form structures such as Figure 1, which is mainly composed of: ⑴ ⑵ stainless steel housing core network transmission ⑶ ⑷ ⑸ sewage gear doors and other five components. How it works: circulating water through the trash rack and a mesh filter still contains a lot of suspended solids and sediment and other impurities, after circulating pump into the secondary filter filtered, when suspended solids in water and sediment and other impurities in the filter When attached to a certain number of the internal and external water pressure filter is increased to a predetermined numerical control system (typically 500mmH2O column), start control system to use, sewerage agencies to work, the discharge secondary filter attachments, to be within When the pressure returned to normal at the (general ≤400mmH2O column) control mechanism closes the cycle, thus completing the process of filtering the sewage work
