1、Automatic self-cleaning filter Operation manual Model CNAF-JTBeijing Luolun (Excel Ethics) filtration Equipment technology Co., Ltd1 Product introductionFiltration is one important part of water purification, which filters the impurity in order to achieve the purpose of water treatment or protection
2、. Traditional net filtration approaches have been widely applied in water treatment and industrial water recycling system owing to its good filtration result and small resistance. However, these approaches have the limit of volume of impurity to be treated, easily blocked and complicated cleaning pr
3、ocess which must be cleaned after the whole system is disassembly. This kind of cleaning process loses the monitor and lowers the automation for whole system. Automatic cleaning filtration filters the grey water and automatically cleans the filter without stopping supplying the water. The system is
4、fully automatic and treats big volume of grey water. Picture 12 Serviceable rangeJT- automatic self-cleaning filter widely applied in circle or acyclic cooling waters system, heat exchanging system, central air-conditioning system, and central heating system, hot-water boiler, which are used to prot
5、ect cooling equipment, heating exchanging system, air condition and boiler. It is suitable to industry circulating water filtrations, such as steel system, petroleum chemical industry, metallurgy, electron, papermaking, food.This equipment requests water temperature flow the filter cant surpass 95.T
6、he request of water quality: The suspended substance in water is smaller than 60mg/L, suspended substance can be allowed to achieve 110mg/L in the short adequate time. If the water quality cannot meet the requirements, it needs to pretreatment before enter to the inlet.3 Product functions and charac
7、teristics3.1 product functionsAutomatic cleaning filtration system filters the grey water and automatically cleans the filter without stopping supplying the water. The system has two control types: Manual and automatic. Automatic control: There are two ways for automatic control. One is timer and th
8、e other is pressure difference. Set the time for the filtration on the timer. When it finishes the cleaning process starts automatically. In the meantime, the control system compares the system pressure difference with pre-set pressure difference. If both differences meet together the system starts
9、the automatic cleaning. The duration is set by the timer. When the cleaning finishes the system goes back to the initial state and is ready for the next cycle. Manual control: Turn the switch to the manual and it starts to clean the filter manually. Customers can choose any model of control accordin
10、g to the need. Please see the details of operation in the operation section. 3.2 product Characteristics1) The default filter fitness is 100 microns and optional from 100 microns to 3000 microns. Moreover, its filter area is large, the pollutional load is high, and user can setting according to actu
11、al working condition.2) It is easy to operate automatic cleaning under the electronic monitor. All parameters for the control system can be adjusted. 3) The system has designed for the over-load motor protector. 4) The system features in non-stop supply of water when the cleaning is processed. It co
12、nsumes little water to clean. The amount of water used is less than 1% of the total amount of water. 5) Easy to maintain and uninstall. 6) The system is designed French connection and easy. 4 Product model descriptionsJT-automatic self-cleaning filters specifications is distinguished by inside nomin
