The non-negative pressure variable frequency water supply equipment refers to the water supply mode in which the outlet pressure remains unchanged when the water consumption in the water supply network system changes. The export pressure value of the water supply network system is determined according to user needs. The traditional constant pressure water supply method is realized by water tower, high water level tank and pressure tank.


In recent years, with the increasing maturity of frequency conversion speed regulation technology, its remarkable energy-saving effect and reliable and stable control mode, non-negative pressure variable frequency water supply equipment has been widely used in water supply systems. The non-negative pressure frequency conversion water supply equipment implements stepless speed regulation on the water pump motor. According to the water consumption and water pressure change, the microcomputer detects and calculates, automatically changes the water pump speed to keep the water pressure constant to meet the water requirement. It is an advanced and reasonable energy-saving water supply system. Compared with traditional water towers, high water tanks, and pressure tanks, it has advantages in terms of investment, economics of operation, system stability, reliability, and automation.

No negative pressure frequency conversion water supply equipment

The commissioning and operation of the non-negative pressure frequency conversion water supply equipment is crucial for the whole equipment. Through the development of modern technology, we have achieved great results in the entire monitoring system, reducing labor costs and improving work. Efficiency, so, before doing work, we must do a good job of its debugging work, of course, in the operation also need to pay special attention to some related operational matters, so as to avoid malfunction.

1. Carefully check whether the wiring is correct, especially the input and output ends of the inverter. The line cannot be reversed, otherwise it may cause serious damage to the water supply equipment without negative pressure.

2. Check whether all parts of the waterway such as the reservoir and the pressurized pipe network are leaking, and if so, remove them in time.

3. Turn on the power, turn the main switch to the manual state, and check the steering of each pump one by one.

4. Turn the main switch of the non-negative pressure water supply equipment to automatic, and put the electric control cabinet into operation.

5. Adjust the parameters of the control cabinet and set the system pressure.


No negative pressure frequency conversion water supply equipment product features

1. Saving investment: saving about 50% of investment, no need to build a water storage tank or roof water tank, using laminated water supply to reduce the initial investment of equipment.

2, high efficiency and energy saving, low operating costs: can make full use of the municipal pipe network water supply pressure, how much, how much, no negative pressure, compared with traditional water supply equipment can save 30% -90%. Power outages can also maintain the water supply to the municipal pipe network.

3, high degree of intelligence, simple operation, saving manpower: The equipment is controlled by a fully automatic intelligent controller, which is adjusted according to the user's water consumption and the tap water pressure of the pipe network, and is unattended. And the use of human-machine interface (text, digital) display, so that customers can more intuitively see the operation of the device.

4. Environmental sanitation: The equipment is fully enclosed and completely eliminated from secondary pollution of water sources.

5, the protection function is complete: with perfect overload, short circuit, over voltage, under voltage, phase loss, over current, short circuit, water source water shortage and other automatic protection functions. Signal alarm, self-test, fault judgment, etc. can be performed under abnormal conditions.

6. Less land occupation and convenient installation: The whole set of equipment has only one set of water supply control cabinet, no negative pressure steady flow tank and water pump unit. The installation is very simple and convenient.

7. Extend the service life of the equipment: It can reliably achieve soft start for multiple pump sets, so that the power grid and pipe network can be shock-free and run in turn, which greatly prolongs the service life of pumps and motors. Equipment life can be extended by more than 3 times.
