Working principle of direct-connected pipe network superimposed high-rise pressurized water supply equipment
The direct-connected pipe network superimposed high-rise pressurized water supply equipment inlet pipe is directly connected to the water pipe network. The water source flows into the equipment inlet pipe under the pressure of the water pipe network pressure and then flows into the non-negative pressure tank, which cleans the negative pressure. Then, the pressurized water pump of the equipment continues to pressurize on the basis of the water inlet pressure, and the water supply pressure is increased to the pressure required by the user, and then the water is supplied to the outlet pipe network; that is, the water is supplied to the user.
1. When the pressure of the tap water is lower than the set pressure required by the user, the control system will automatically control the inverter's frequency conversion soft start operation until the actual working pressure of the user's pipe network is equal to the set pressure. Speed running, the higher the pressure of the tap water, the lower the speed of the variable frequency pump, the lower the pressure of the tap water, the higher the speed of the variable frequency pump. When the pressure of the tap water is equal to the set pressure, the variable frequency pump will delay sleep, that is, Make full use of the original pressure of the tap water to ensure the constant pressure required by the user. When the pressure drops to the awake value, the pump automatically wakes up.
2. The water inlet of the variable frequency pump is connected to a stainless steel steady flow compensator. The microcomputer detects the pressure of the steady flow compensator at all times. Through the water inlet pressure detection and the vacuum automatic suppressor, it is ensured that no negative pressure is generated in the voltage stabilizer compensator, thereby ensuring tap water. The normal water supply of the pipe network.
3. The tap water stops, the equipment automatically stops, the tap water starts automatically, and the power supply restores the normal pressure water supply of the tap water.
4. When the instantaneous negative pressure is generated, all the industrial frequency pumps are stopped first, and then the inverter is decelerated by delaying frequency conversion without stopping, which can ensure the user's water consumption and alleviate the negative pressure situation.
Advantages of direct connected pipe network superimposed high-rise pressurized water supply equipment:
1.No need to build high-level water tanks and pool water tanks-clean, sanitary, efficient, energy-saving, and cost-saving
Zhongying series of direct-connected pipe network superimposed high-rise pressurized water supply equipment is economical and hygienic, making full use of the pressure potential energy of municipal water sources, and maximizing the energy saving effect of frequency conversion speed regulation. Practice has proved that the use of direct-connected non-negative pressure water supply equipment can save more than 50% of the cost of building a pool, compared with other water supply equipment, can save 20% -60% of electricity.
2.Low running noise
Zhongying series of directly connected pipe network superimposed high-rise pressurized water supply equipment uses variable frequency speed control, especially the full frequency control system, most of the time, especially at low speed and low noise operating conditions.
3. Clean and sanitary without pollution
Zhongying series of directly connected pipe network superimposed high-rise pressurized water supply equipment uses a fully enclosed diaphragm tank with both buffering and dynamic compensation functions, which is more practical than the ordinary non-negative pressure water supply equipment on the market. And simplify the control system.
4, advanced products, reliable quality, high degree of standardization, good versatility
The win-win series of directly connected pipe network superimposed high-rise booster water supply equipment adopts a standardized and universal control system technology solution. Key components in the product, such as: motors, pump bearings, inverters, regulators, PLCs, and other components are used. With international and domestic famous brands, it is easy to debug and maintain.
5, full-featured, high degree of intelligence, strong adaptability
Zhongying series directly connected pipe network superimposed high-rise supercharged water supply equipment uses advanced frequency conversion control technology, soft start, overload, short circuit, overvoltage, undervoltage, phase loss, overheating and stall protection functions. Under abnormal conditions, it can perform signal alarm, self-test, fault judgment, etc. It can also automatically adjust the water supply flow according to the level of water consumption. When the inverter fails, it will be automatically degraded (becoming a power-frequency automatic water supply equipment). When the automatic system fails, you can also manually operate the emergency backup to win maintenance time.
