Automatic softener
Ⅰ、An overview of the
The automatic water softener is a new green, economical and safe water treatment system based on the national industry standard and a lot of successful engineering practice experience. Based on the design principle of end-user requirements, combined with raw water pretreatment, water quality monitoring and deployment system, the adaptive equipment is selected to form an automatic sodium ion exchange soft water system. It has solved many problems, such as high operating cost, frequent equipment failure, unqualified effluent water quality, water quality not matching user's demand, etc. caused by users' single use of water softener.
Ⅱ、The working principle
Hydraulic control valve uses the kinetic energy of water flow to drive two sets of turbines to drive two sets of gears to drive the rotation of water dial and control panel respectively. The water dial accumulates the flow through, and the control panel introduces the raw water pressure signal into a set of valve chambers through a set of channels. At the same time of rotation, the pressure channel is opened or closed according to the set rules, so as to realize the automatic switch of an integrated set of valves.
QC - RST series softener by two resin tank (the main tank and tank) box of three parts, hydraulic control valves, salt water control valve control switch between the main tank and deputy tank, make sure that there is always a tank is in working status, while the other pot in regeneration or standby state, regenerated salt solution by negative pressure suction valve installed inside venturi injector, regeneration and cleaning water is another softened water tank. For different hardness of raw water with different numbers of water dial to achieve the corresponding work and regeneration cycle.
The hardness of water is mainly composed of cations: calcium (Ca2+) and magnesium (Mg2+) ions. When the hardness of raw water by exchange resin layer, the calcium and magnesium ions in the water by resin absorption, at the same time release sodium ions, this switch is to remove the flow of water in the softening of water hardness ions, when the resin absorption of calcium and magnesium ions after reaching a certain degree of saturation, increase the hardness of water, the water softener will be carried out in accordance with the scheduled program automatic failure of the resin regeneration work, with a high concentration of sodium chloride solution (brine) through resin, to restore failure of the resin to sodium to resin.

Key points of construction and installation
1)、Pipeline should be equipped with stress support to prevent stress on the control valve.
2)、When the water inlet pipe of the water softener is connected with the domestic water pipe, a backflow preventer shall be installed on the water inlet pipe.
3)、If the inlet water pressure is lower than 0.15mpa, pressure measures shall be adopted.
4)、The length of the blowdown pipe shall be less than 6m; There is no valve on the pipe; Exit not higher than valve body, end opening, to avoid siphon.
5)、In addition to the water softener with hydraulic drive multiway valve, 220V power supply is required on site.
6)、Do not use iodized salt, use calcium salt as a regenerator.

Ⅴ、Equipment advantages
1.With high degree of automation, the automatic water softener automatically completes the cycle process such as softening and regeneration according to the preset program. In operation, there is no need for any manual operation except the regular addition of reclaimed salt manually, which saves a lot of manpower and material resources. Automatic controller or computer automatic controller (optional) allows users to easily adjust the operation of the system according to changes in water quality.
2.According to the local water quality conditions, the precise setting procedure of the soft water device can guarantee the quality of the effluent under any working condition.
3.High efficiency, low energy consumption, low operating cost due to the water softener overall reasonable design, and the implementation of strict automatic control, so that the resin exchange capacity to ensure full play, so that the equipment salt consumption, water consumption and other indicators are significantly lower than the general water softening device, power consumption significantly reduced.
4.Reliable operation, long service life of DM water softening device switch shell adopts special high strength glass fiber reinforced plastic and composite materials, corrosion resistant, anti-aging, useful life of 50 years, automatic control valve structure design is unique, the valve core is the only moving part, these features make the control valve of reliable performance, long service life.
5.The small floor space and advanced technology design make the soft water device compact in structure, reduce the floor space obviously, and save the construction investment.
6.Widely used in electronic and electric power industry, metallurgy industry, pharmaceutical industry, chemical industry, food and beverage industry, hotels and restaurants, thermal stations, boiler rooms, office buildings, cold storage, shopping malls, air conditioning water, and domestic water softening treatment; Used for water softening treatment of various boilers such as heating, heating and gas supply; It can be used for drinking and bathing water to reduce the hardness of raw water.
