Principle, composition, working process and process of no tower water supplyapplication

   1, principle: no tower water supply is pressure water supply;

     2Composition: no tower water supply is composed of no tower water supply (pressure tank), pressure switch, pressure gauge, water pump, pipe network and matching valves. It is divided into two parts: pipeline and circuit.

3, working process: no tower water supply (pressure tank) with uniform atmospheric pressure, installation of pressure switch, pressure gauge and pipe network to become a sealed container. When the water pump starts, the water level in the tank rises, the air in the tank is compressed and the air pressure is produced. The pressure reaches the set pressure (such as 0.28mpa), and the pump stops working. The water in the tank can flow out at high speed because of the air pressure. After lowering the water level in the tank, the air pressure is reduced, reaching the set pressure (such as 0.14MPa), and the pump starts automatically, and starts automatically again and again. The essence is a small household water supply system.

4, characteristics and application:

4.1 as a set of household tap water, it can make the farmers' friends and enjoy the same convenience and health as the urban residents.

4.2 no tower water supply pressure, high speed, can meet the solar energy, water heater, washing machine, toilet urinal water pressure requirements, instead of the traditional water tank, water storage, water jar.

When the water pressure of tap water is insufficient in 4.3 cities, two booster can be used.

4.4 can be used for fire protection, agricultural irrigation, and centralized water supply.

Two, pressure, pressure gauge, pressure switch and circuit

1, pressure: the pressure of this product is pressure, unit Mpa (Zhao Pa). 0.1Mpa, the force of 1 kilograms, can increase the water by 10 meters.

2, pressure meter: display pressure index instrument, interface thread has M14 and ZG1/4 two kinds.

3. Pressure switch:No tower water supply can automatically circulate, mainly rely on pressure switch to detect the pressure inside the tank and control the work of the pump. According to its working pressure, it can be divided into three kinds: BSK1 type: 0.11Mpa---0.19MpaBSK2 type: 0.14Mpa---0.28MpaBSK3 type: 0.21Mpa---0.35Mpa, rural residential three storey building, water height is in 10--15 meter, mainly used the first two kinds. 4, the circuit power supply is single phase 220V, 10A current. The power supply is first connected to the pressure switch and then connected to the pump. When you install, please read the instructions in detail, pay attention to earth protection three, pipeline technology, no tower water supply is made up of pressure tank, water pump, check valve, three way, stop valve and water pipe. 1 water pump: the submersible pump and the self-priming pump can be used with the no tower water supply. Under normal circumstances, the brand submersible pump uses single-phase 750W and 1 inch caliber. The brand self priming pump selects single-phase 1000W and 1 inch caliber. The non brand submersible pumps and self priming pumps must be 1.1KW or 1 inch. 2 check valve: check valve 1 to prevent water flow back valve 2 to fill the gas function. When the check valve 1 is out of order, the water in the tank will flow back to the pump to form a negative pressure and can draw the tank flat; and the check valve is 2 to the gas supplement to prevent negative pressure. (the check valve must be installed 2! ) 3, the cut-off valve is installed at the inlet and outlet, so as to facilitate the maintenance and maintenance of the valve.4, the circuit power supply is single phase 220V, 10A current. The power supply is first connected to the pressure switch and then connected to the pump. When installing, please read the instructions in detail and pay attention to the grounding protection.


Three, pipeline technology without tower water supply by pressure tank, water pump, check valve, three, cut-off valve, water pipe.

1 water pump: the submersible pump and the self-priming pump can be used with the no tower water supply. Under normal circumstances, the brand submersible pump uses single-phase 750W and 1 inch caliber. The brand self priming pump selects single-phase 1000W and 1 inch caliber. The non brand submersible pumps and self priming pumps must be 1.1KW or 1 inch.The above water pump selection standard is suitable for the plain area. Because of the difference of terrain, geomorphology and underground level in each area, the selection of water pumps is also very different. We provide a basic selection calculation method for reference.
Submersible pump lift: the vertical distance of +35 meters from the pump to the tank
Self-priming pump: 2 m + horizontal plane under horizontal plane to the vertical distance of tank
Self priming pump head: 30---35 meters
 

2 check valve:

Check valve 1 to prevent water flow back flow

The check valve is 2 to fill the air. When the check valve 1 is out of order, the water in the tank will flow back to the pump to form a negative pressure and can draw the tank flat; and the check valve is 2 to the gas supplement to prevent negative pressure. (the check valve must be installed 2! )

3.The cut-off valve is installed at the inlet and outlet, which is convenient for maintenance and maintenance.
