Imported automatic type in Europe and America since the 1960s began to ion exchange equipment to automate the design, along with the development of industrial technology, and gradually developed a multi-way valve and domestic is not the same multi-way valve and integrated valve, mainly in the multi-way valve, the main materials are plastic and lead-free brass two. The core components of a multi-channel integrated valve, the valve plate or the general direction of flow control piston, camshaft driven by a small motor (or piston) to action. Because of the level of development of industrial technology abroad is better, so this type of equipment has been developed quite perfect, product specifications from the home of 0.2t / h to industrial 70t / h or so have high degree of automation controller (already available with the latest industry Ordinary computer or monitor computer communications). 4. Automatic discrete valve types: discrete valve is generally used imported automatic diaphragm or solenoid valve, using the traditional manual mode similar structure, with special automatic controller (MCU or PLC) to form water softening equipment . Automatic type equipment is mainly used for large flow applications, can also be used to transform the traditional manual device, you can, without changes to the original equipment pipeline will transform the traditional manual devices into automation equipment. Thereby reducing the labor intensity, reduce equipment consumption. Fifth, a water softening equipment selection, first you need to provide is the use of demineralized water system which: 1) heating 2) cooling water 3) process water 4) steam boilers 5) iron and steel smelting industry 6) chemical and pharmaceutical industries 2, the system water time: the running time / h of water / average / peak / device needs a continuous supply? If you need to select the Twin centralized control or dual control Twin series, otherwise the menu valve single tank series. 3, the source of water is municipal tap water total hardness \ Groundwater \ surface water, the use of the total area of ??the raw water hardness. For certain types of raw water softener for high hardness, the water cycle system is bound to be reduced, thus resulting in frequent regeneration softener equipment. Relatively reduce the life of the resin. To avoid such situations, you should increase the volume of the resin, which means that the choice of models to increase water softener. 4, the desired soft water per unit flow rate (tons / hour). This may be determined by the nature and requirements of the user equipment; 5, water cycle system is set after set softener models, based on the raw water hardness, work exchange capacity of the resin used can determine the theoretical water cycle system (t). Sixth, the application of water softening equipment: can be widely used to soften steam boilers, hot water boilers, switches, evaporative condensers, air conditioning, direct gas turbine systems, water supply. Softened water treatment can also be used in hotels, restaurants, office buildings, apartments, homes and other domestic water treatment and food, beverage, wine, laundry, printing and dyeing, chemical, pharmaceutical and other industries.
