What are the common types of water softeners?
3) import automatic type: Wright RyderIn Europe and the United States, since 1960s began the automaticdesign of ion exchange equipment, with the development of industrial technology, developed the multi way valve is not the same with the domestic valve and integrated valve, mainly valve, the main materials for engineering plastics and lead brass two.The core component of a multi-channel integrated valve, generally use the valve plate or piston to control the flow direction, by a small motor drives the camshaft (or piston) to action. Because of the development level of industrial technology abroad is good, so this kind of equipment has developed very perfect product specifications from domestic 0.2t/h to industrial were about 70t/h controller, high degree of automation (the latest can communication with the industrial computer or ordinary computer monitor).4) discrete valve fully automatic type:Discrete valve is generally imported automatic diaphragm valve or solenoid valve, using a similar structure with the traditional manual method, with a dedicated automatic controller (SCM or PLC) to form softened water equipmentFull automatic equipment is mainly used for occasions of heavy traffic, can also be used for the transformation of traditional manual equipment, can not change the original equipment pipeline under the condition of manual equipment transformation of traditional automation equipment. So as to reduce the labor intensity of the operation, reduce the equipment cost.
The main features of water softening equipment of this structure are: the process is simple and easy to understand, easy operation, low cost, can be used to flow; but backward technology, large occupied area, operation consumption is large, the actual operation intensity, corrosion salt pump heavy and high maintenance costs.2) domestic combined automatic type:Due to the use of manual equipment is too complex, in early 1990s, the emergence of a new equipment to combined integrated valve as the core. The core component of this equipment is a multi-channel integrated valve, through the rotation of the valve body to change the direction of water flow. This equipment is compared with the traditional manual equipment, compared to the manual the traditional equipment and equipment, equipment covers a lot of small, high degree of automation. But the control method using time control, operation control precision is low. By the design, process and material constraints, with the majority of planar integrated valve equipment easy to wear, wear after repair once the possibility is very small. At present many of the domestic market for this kind of equipment manufacturers, the actual differences in the quality of products is large, a lot of equipment running effect is not satisfactory.
What are the commonly used softening methods? At present, the domestic commonly used softening water equipment mainly has the following kinds:1) manual type:This is the standard way of traditional, mainly downstream / top pressure free countercurrent two forms, usually two parallel steel tank structure, according to different processes, each tank with 8-11 only need manual valves (two tank with 16-20 valve, then left and right) students with salt pump special will be dissolved good salt liquid pump into the resin tank (this equipment was the main form of domestic water softening equipment).
