The main functions and application areas of non-negative pressure water supply equipment

along withNon-negative pressure water supply equipmentWith the strengthening of promotion, more and more people pay more attention to it. Among them, the function of non-negative pressure water supply equipment is the most important, so the following will focus onNon-negative pressure water supply equipmentSeveral main functions and application areas.

First, main functions

1. No negative pressure function

The non-negative pressure water supply equipment is directly connected to the municipal pipeline network. The equipment does not generate any negative pressure impact on the pipeline network when working. Through the effective operation of the equipment's microcomputer control system, steady flow compensation system and vacuum suppression system, it automatically monitors, adjusts and adapts at all times to achieve automatic compensation of the suction distance by pre-pressure, thereby eliminating the negative pressure and suction distance generated when the water pump is running. It will never affect the municipal pipeline network and its surrounding water users, and will never cause negative pressure in the pipeline and the resulting air bags, air resistance, pressure oscillations, backflow and water hammer, which are important factors that endanger the safety of the pipeline network or cause hidden dangers.

2. Automatic constant pressure function

According to the actual situation of the project, the outlet pressure of the non-negative pressure water supply equipment can be set on site. The control system has a fast operation speed, and the outlet pressure is always detected and compared with the set pressure, and automatically adjusted to make the outlet pressure very constant. The constant pressure control accuracy is ≤±0.01Mpa. The equipment can realize constant pressure control of pressure sampling at the water outlet of the equipment, pressure sampling at the most unfavorable water point, pressure sampling at any point in the middle of the water supply pipeline, and multi-time constant pressure control, variable pressure control and other control functions.

3. Frequency conversion and timing switching function

When one water pump running at full speed still cannot meet the water demand, the non-negative pressure water supply equipment automatically controls other water pumps to start running and keeps the water pumps in an efficient operating state at all times; when one water pump runs for a long time, the equipment can automatically adjust other water pumps to work, effectively regulating the running time of the water pumps, making the utilization rate of each water pump tend to be equal, avoiding damage to the water pump due to unbalanced water pump utilization, thereby greatly extending the service life of the equipment.

4. Automatic compensation and pressurization function of the pipeline network

The non-negative pressure water supply equipment is directly connected in series with the water pipe network, making full use of the original pressure of the water pipe network. The frequency conversion speed control technology is used to compensate for the difference between the inlet pressure of the tap water and the set outlet pressure, making full use of the pressure of the municipal pipe network and achieving high efficiency and energy saving.

5. Pipeline network overpressure protection function

For high-lift domestic water supply equipment, the outlet pressure of the non-negative pressure water supply equipment is very high. This function is added to prevent the pipe network from overpressure when the municipal pipe network pressure is unstable. When the equipment is in automatic operation, the pipe network pressure exceeds the set overpressure protection pressure, the equipment voice alarm "pipe network overpressure" and adjust the working state to prevent the pipe network pressure from being too high, effectively protect the safety of the water pipe network, and avoid the frequent overpressure damage to the pipe network in high-rise buildings.

6. Fault alarm and processing function

When the non-negative pressure water supply equipment encounters overcurrent, overload, overvoltage, phase loss, overheating, undervoltage and other conditions that are not suitable for the equipment to work during operation, the equipment can automatically switch to the protection state to protect the equipment from damage. At the same time, the equipment automatically skips the faulty circuit or water pump and puts other circuits or water pumps into use to avoid unnecessary equipment shutdown affecting user water use. At the same time, an alarm signal is issued to handle the fault on-site or remotely through local control, remote control and on-site control.

Second, application area

1. In production, such as factories, manufacturing, food industry, and washing equipment.

2. Residential water use, such as villa areas, high-rise buildings, and residential water areas, etc.

3. Public places, such as airports, hospitals, golf courses, primary and secondary schools, universities, gymnasiums, etc.

4. Commercial buildings, such as large sauna centers, bathing pools, hotels, department stores, office buildings, etc.

5. Irrigation areas, such as farms, parks, orchards, planting areas, playgrounds, etc.

6. Other places, such as pools or other forms of water supply bases.

There are many places where non-negative pressure water supply equipment can be used. As long as you pay a little attention, you will find that non-negative pressure water supply equipment can be seen everywhere in our lives, making our lives more convenient.
