No negative pressure frequency conversion stainless steel water supply equipment
No negative pressure frequency conversion stainless steel water supply equipment The non-negative pressure frequency conversion stainless steel water supply equipment uses the municipal pipe network as the water source, making full use of the original pressure of the municipal pipe network to form a closed continuous relay pressurized water supply mode, which has good energy saving effect and no secondary pollution of water quality. Development and extension of pressure water supply equipment. On the basis of the pressure of the municipal pipe network, the water supply is directly superimposed to save energy, and it also has many advantages such as full closure, no pollution, small land occupation, quick installation, reliable operation and convenient maintenance....

The non-negative pressure frequency conversion stainless steel water supply equipment uses the municipal pipe network as the water source, making full use of the original pressure of the municipal pipe network to form a closed continuous relay pressurized water supply mode, which has good energy saving effect and no secondary pollution of water quality. Development and extension of pressure water supply equipment. On the basis of the pressure of the municipal pipe network, the water supply is directly superimposed to save energy, and it also has many advantages such as full closure, no pollution, small land occupation, quick installation, reliable operation and convenient maintenance.


The non-negative pressure frequency conversion stainless steel water supply equipment is put into use, the water of the water pipe network enters the steady flow flow tank, and the air inside the tank is discharged from the vacuum eliminator, and after the water is full, the vacuum eliminator is automatically closed. When the pressure of the water pipe network can meet the water demand, the system directly supplies water to the water supply network by the bypass check valve; when the pressure of the water pipe network cannot meet the water demand, the system pressure signal is fed back to the frequency conversion controller by the remote pressure gauge. The pump runs, and automatically adjusts the speed constant pressure water supply according to the amount of water consumption. If the running water pump reaches the power frequency, the other pump starts the frequency conversion operation. When the water pump supplies water, if the water volume of the water pipe network is greater than the water pump flow rate, the system maintains the normal water supply: if the water supply volume is less than the small pump flow rate, the water in the steady flow tank can still supply water normally as a supplementary water source. The air enters the steady flow tank by the vacuum eliminator, and the vacuum inside the tank is destroyed, ensuring that the tap water network does not generate negative pressure. After the water peak, the system returns to the normal water supply state. When the water pipe network stops water, the liquid level of the steady flow tank is continuously decreased, and the liquid level detector feeds back the signal to the frequency conversion controller, and the water pump automatically stops to protect the water pump unit. When the small-flow water supply at night and the pressure of the water pipe network can not meet the requirements, the pressure tank can store and release energy, avoiding the frequent start of the pump.

No negative pressure frequency conversion stainless steel water supply equipment

Seven advantages of no negative pressure frequency conversion stainless steel water supply equipment:

A. No pollution: There is no tank and water tank, and the water is completely sealed and closed, and there is no secondary pollution.

B. Low investment: no need to build tanks and water tanks, no need to clean and disinfect frequently, save 50% of construction costs and post-cleaning protection fees.

C. Small land occupation: there is no need to build a tank and a water-filled box. The facility occupies a small space. The vacated pool location can even be used as a parking space to increase revenue.

D. Good energy saving: make full use of the pressure of urban management work network, the difference is a little, make up a number; when the water supply pressure is satisfactory, the facility is in a shutdown state, and when the water supply pressure is insufficient, the facility starts to work semi-automatically. It is 20%~80% more energy efficient than traditional water supply facilities.

E. The water pressure is stable: the outlet pressure is measured by the sensor in real time, and the frequency control is used to ensure the effluent pressure is permanently fixed.

F. Simple and convenient installation: The complete set of facilities is factory-made, small in size, and can be directly connected with the pipeline inlet and outlet, and the construction period is short.

G. Convenient management: The facility is fully semi-automatically operated, and the facility has reload, short circuit, over current, water shortage and semi-automatic reset.
