Steady flow tank

  Steady flow tank is also called negative pressure tank,Contains negative pressure eliminator, etc.,Mainly used in the present In high-rise water supply equipment,It is an indispensable component of non negative pressure water supply equipment.

Negative pressure control technology

The system will set a constant pressure value, if the pipe network pressure is higher than the set pressure value, the pressure transmitter will feedback the pipe network pressure to the frequency conversion control cabinet, the tap water can directly arrive the user pipe network through the direct supply pipeline to carry on the water supply for the user. When the pressure of the municipal pipe network or the change of the water consumption of the user pipe network makes the pipe pressure lower than the set pressure, the pressure transmitter can feedback the pipe network pressure to the frequency conversion control cabinetPlDController, throughPlDThe controller adjusts the output frequency of the inverter, starts the water pump set and adjusts the speed of the pump to keep constant pressure water supply; if the water supply requirement can not be met, the control cabinet will control the start stop of the multi frequency power pump and the speed of the variable frequency pump, so as to achieve the requirements of constant pressure variable water supply.

Negative pressure elimination technology

   Non negative pressure equipment adopts microcomputer frequency conversion technology and effective negative pressure treatment technology to realize pressure superposed water supply. Specific as follows: the equipment through the steady flow tank vacuum compensation system and fully enclosed structure to achieve a direct connection with the tap water pipe network, and overcome the adverse impact on the pipe network. The device through the pipe pressure gauge, vacuum suppressor and compensator in the detection device for collecting the steady flow tank within the vacuum and water level signal, real-time feedback, through the microcomputer control device and special vacuum suppressor compensator in the suppression of negative pressure, ensure steady flow can affect the city network equipment does not eliminate the negative pressure.

When the municipal pipe network is stopped, the water pump unit can still work until the pressure in the steady flow tank drops to the lower limit set by the electric contact and stops automatically, and the water pump is automatically started after the water is put in. When the power failure occurs, the pump unit stops working, and the tap water can enter the user's pipe network through the through pipe. When the incoming call, the unit automatically starts to return to normal water supply.

Negative pressure suppression system

According to the conditions of negative pressure generation, the intelligent control technology is adopted, and the operation condition of the equipment is automatically controlled according to the requirements of the pipe network, so as to eliminate the negative pressure in the steady flow tank. When the pressure of the main network in the setting of protection pressure when running over equipment, normal water supply, when the pressure of the main network in the setting of protection pressure following operation of water supply equipment, water buck, automatic adjustment of equipment operating conditions, when the pressure of the main network to further reduce restrictions on the use of pressure, water supply equipment to stop running, the equipment to meet the network constraints smooth, stable adjustment of the pump outlet flow, the maximum meet user requirements.

Product use

New residential areas or buildings and other domestic water;

The water supply mode of pool and water tank has been built, in order to eradicate the pollution of water thoroughly;

Production and living water for industrial and mining enterprises;

Urban water supply system long-distance water supply intermediate pressure station, regional water supply network pressurization station, high position centralized water supply pressure station.

Product features:
1., the equipment investment province needs no construction of pool or water tank, also does not need to set large pressure tank, saves a large amount of investment, and can make full use of tap water pipe network in turn, water pressure, pressure pump type selection can be reduced, equipment investment reduced.


2. sanitary non polluting water supply system from tap water pipe network to user faucet is totally enclosed structure. Pollutants will not enter the system, the water body is not directly contact with the air, the filter parts are made of food grade stainless steel, there is no two chance of pollution, environmental protection and sanitation.


3. significant effect in energy saving equipment directly and is connected with the tap water pipe network pressure superposed on the basis of a water supply tap water factory on the required pressure, how much worse, how much make up, can make full use of the residual pressure of the water pipe network, low peak period, do not even need to run equipment, energy saving effect is remarkable, and the traditional water supply equipment than. Such as 30%-90%.


4. Water resources are not cleaned regularly, and waste water and human resources are not wasted. Maintenance cost.


5., small area, no need to build a reservoir or water tank, do not need to configure large pressure tank, greatly saving the system area, can save land to improve the real estate utilization rate, in line with national land conservation requirements.


6. the bottom of the operation cost is smaller because of the selection of the pressure pump, and the water supply can be connected by multiple pumps. The water supply is directly supplied by the water directly in the city with low water peak, and the equipment does not need to start the pump. Therefore, the energy consumption is very low during the operation of the equipment, and the operation cost is reduced.


7. the water supply will not stop when the water supply is insufficient, the new generation of pipe network superposed pressure (non negative pressure) water supply equipment developed by our company adopts advanced computer fuzzy control principle, and the normal water supply can be guaranteed when the water supply is insufficient.

 

8 easy to install equipment to the scene, only need to connect the water pipe, the construction cycle is short, according to the installation simple.


9 management and maintenance simple for equipment, there is a public water supply pipe and the user network directly interlinked, when listening to electricity, although the pressure pump stops working, but the water supply plant water supply pressure can still maintain water supply.


10 water supply pump with good performance, good pipe network pressure superposed water supply device for automatic control of variable speed power crisis, automatic shutdown device, automatic call boot, after clap can lie detection, diagnosis and alarm reminding device management and maintenance is simple due to the abnormal will not produce pollution, so no cleaning trouble.


11 water supply pump with good performance, good equipment adopts multistage stainless steel pressure pump, pump casing, impeller and the main parts are made of food grade stainless steel stamping or casting wit, smooth circulation, high efficiency and energy saving, and smooth running, low noise, excellent performance, is the ideal green energy saving water by equipment.
