1. [Softening Water Equipment] Working Principle:

The hardness of water is mainly composed of cations: calcium (Ca2+), magnesium (Mg2+). When the raw water containing hardness passes through the resin layer of the exchanger, the calcium and magnesium ions in the water are absorbed by the resin, and the sodium ions are released at the same time. In this way, the water flowing out of the exchanger is the softened water that has lost the hardness ions in the water equipment of the electronic industry. When the resin adsorbs the calcium and magnesium ions to a certain degree of saturation, the hardness of the outlet water When the water softener increases, the regeneration of the failed resin will be carried out automatically according to the scheduled procedure, and the resin will be restored to the sodium resin by using a higher concentration of sodium chloride solution (brine) through the resin.

2. Main characteristics of water softening equipment:

1. High degree of automation, stable water supply conditions and long service life. The whole process of desalination equipment is automatic, only need regular salt addition, without manual interference.

2. High efficiency, low energy consumption and low operation cost. Because the overall design of the softener is reasonable, the exchange capacity of resin can be fully developed, the energy consumption index of the equipment itself is significantly lower than that of the general softening water equipment, and the automatic control equipment does not need full-time operators, which brings many conveniences to users and produces good economic benefits.

3. The equipment is compact in structure and occupies a small area. It does not need special equipment foundation. It can be placed on the flat cement floor.

4. Easy to use, easy to install, debug and operate, stable performance of control components can relieve users'worries.

5. Corrosion-resistant, pollution-resistant, lead-free brass control valves, exchange tanks lined with non-toxic PE plastics, salt boxes made of PE plastics, these are enough to ensure the excellent performance of the equipment in corrosion resistance, pollution resistance, non-toxicity, tasteless and harmless.

3. [Softening Water Equipment] Application Scope:

Industrial boilers, central air conditioners, heat exchangers, hotels and restaurants, food and chemical industry, laundry, printing and dyeing, health care and other industries need to soften water quality to prevent fouling.

4. Product structure of softening water equipment:

The automatic water softener is mainly composed of three parts:

1. American original controller (including computer controller and multi-directional catchment valve system);

2. The parts of tanks imported or made in the United States (including exchange tanks and salt tanks, which can be made of fiberglass reinforced plastics, carbon steel lining and stainless steel);

3. Equipment accessories (including upper and lower water distributors, central pipes, salt valves, salt wells, salt pipes, sewage pipes, filters, solenoid valves, etc.);

Technical specifications of automatic water softener:

1. Influent pressure: 0.25-0.45 MPa, the best is 0.3 MPa;

2. Influent hardness: <6.5mmol/L (if the hardness of raw water exceeds this index, it needs to be redesigned);

3. Water hardness: <0.03 mmol/L;

4. Raw water temperature: 2-50 C;

5. Power supply: AC22DV50Hz, power 10-50W;

6. Resin type: 00lx7 strong acidic cationic resin (imported and domestic brands can be selected);

7. Valve body material: high-strength plastic or brass;

8. Tank material: FRP winding (carbon steel liner and stainless steel tank can be configured according to requirements);

9. Water consumption: <2% of water production; Salt consumption: <100g/g equivalent; Electricity consumption: 3-40W

Fully automatic water softener is to realize automatic control of every step of softener operation and regeneration, and start regeneration by means of time, flow or other sensors. The basic components of the automatic water softener are: FLECK or Autotrol multi-way control valve, resin tank (containing 001 * 7 resin), salt tank and pipeline system.

5. Characteristics of Softening Water Equipment:

Water quality softening process automation: The equipment realizes the automation of ion exchange and resin regeneration process through program control device.

Efficiency: The design of softener is reasonable, so that the effective exchange capacity of resin can be brought into full play.

Save labor: No need for special operation, easy installation.

Non-toxic: The valve body is lead-free brass or engineering plastics.

Water saving: water production rate is over 98%.

Power saving: Because of the siphon principle, no salt pump is needed for regeneration.

Easy to adjust: regeneration cycle and time can be adjusted according to need.

Anti-corrosion of tank body: The tank body is made of stainless steel, fiberglass reinforced plastic and steel lining material to avoid resin pollution.

Wide applicability: It can be used in industrial boilers, heat exchangers, air conditioners, laundry, bathing equipment and food, pharmaceutical, electronic and other industries.
