PBWS Non-negative Pressure Water Supply System
Product Introduction
Traditional water supply methods often rely on water storage tanks, which are supplied by tap water pipelines. However, this process can result in wasteful energy consumption. When pressurized water enters the tank, the pressure becomes zero, leading to a loss of energy. But worry not, because our company has developed a solution.
PBWS Variable Frequency Speed Regulation Non-Negative Pressure Water Supply Equipment is a comprehensive water supply system designed by our professional technicians. It addresses the inefficiencies of traditional methods and offers numerous benefits.
One of the major advantages of our equipment is its energy and cost-saving features. With PBWS, you no longer need to build a water storage pool, eliminating the expenses associated with construction. Studies have shown that using our frequency conversion speed regulation system can save over 50% of pool construction costs. Additionally, compared to other water supply systems, PBWS equipment can save between 30% to 40% of electricity consumption.
Not only does our equipment save money, but it also comes with a multitude of features and a high level of intelligence. PBWS utilizes advanced frequency conversion control technology, providing soft start, overload, short circuit, overvoltage, undervoltage, phase loss, overheating, and stall protection functions. Even under abnormal circumstances, such as signal alarms and faults, PBWS can perform self-checks and fault judgments. It is also capable of automatically adjusting the water supply flow based on the level of water consumption.
In summary, PBWS Variable Frequency Speed Regulation Non-Negative Pressure Water Supply Equipment offers an energy-efficient, cost-effective, hygienic, and intelligent solution for all your water supply needs. Say goodbye to wasteful energy consumption and unnecessary construction expenses. Choose PBWS and enjoy the benefits of cutting-edge technology and substantial savings.
Structural characteristics
1. No need to build a water pool – energy-saving and cost saving
The PBWS series variable frequency speed regulation non negative pressure water supply equipment has significant economic, health, and energy-saving effects. Practice has shown that using variable frequency speed regulation non negative pressure water supply equipment can save more than 50% of the construction cost of water tanks, and can save 30% to 40% of electricity compared to other water supply equipment;
2. Easy installation and saving floor space
The PBWS series variable frequency speed regulation non negative pressure water supply equipment can be equipped with both horizontal and vertical flow stabilizing tanks. The two types of flow stabilizing tanks have different characteristics: horizontal flow stabilizing tanks occupy less space; The vertical steady flow tank occupies a small area. The manufacturing and inspection of the steady flow tank comply with the provisions of GB150 “Steel Pressure Vessels”, but since there is no compressed gas stored in the tank, it does not need to be included in the management scope of pressure vessels. The inner wall of the tank adopts the advanced “841 cyclohexane polykolamine Food contact materials inner wall coating” for corrosion prevention, and the product meets the Shanghai Food Hygiene Standard: (This sample only lists the horizontal steady flow tank type, if it needs to be equipped with a vertical steady flow tank, it can be provided separately)
3. Wide range of applications and strong applicability
The PBWS series variable frequency speed regulation non negative pressure water supply equipment can be used for domestic water supply and fire water supply. It can be equipped with any type of water pump. When the equipment is used for fire protection, it is advisable to equip it with a dedicated fire water pump.
4. Fully functional and highly intelligent
The PBWS series variable frequency speed regulation non negative pressure water supply equipment adopts advanced variable frequency control technology, with soft start, overload, short circuit, overvoltage, undervoltage, phase loss, overheating, and stall protection functions. In abnormal situations, it can perform signal alarms, self checks, fault judgments, etc. It can also automatically adjust the water supply flow according to the level of water consumption;
5. Advanced products with reliable quality
The accessories used in the PBWS series variable frequency speed regulation non negative pressure water supply equipment have been screened by many manufacturers and have reliable quality assurance. The key components in the product, such as motors, water pump bearings, frequency converters, circuit breakers, contactors, relays, etc., have also adopted international and domestic famous brand products;
6. Personalized design and uniqueness
The PBWS series variable frequency speed regulation non negative pressure water supply equipment can be equipped with a small air pressure tank based on the stable pressure of the tap water pipeline network to avoid frequent start of the water pump and extend the service life of the equipment. Its storage and pressure stabilization performance is more significant. (May be specified separately)
scope of application
1. Pressurization technology suitable for any area with insufficient tap water pressure:
2. Domestic water for newly built residential communities or office buildings.
3. Low level tap water pressure cannot meet the fire water requirements
4. If the water tank has been renovated and built, a water supply method that shares negative pressure equipment with the water tank can be used to further save energy.
5. A booster pump station in the middle of a wide range of tap water supply.
6. Production and domestic water consumption of industrial and mining enterprises.
Conditions of Use
Working principle
When the equipment is put into use, the water from the tap water pipe network enters the steady flow tank, and the air inside the tank is discharged from the vacuum eliminator. After the water is filled, the vacuum eliminator automatically closes. When the pressure of the tap water pipeline network can meet the water consumption requirements, the system directly supplies water to the water pipe network through a bypass check valve; When the pressure of the tap water pipeline network cannot meet the water consumption requirements, the system pressure signal is fed back to the variable frequency controller by the remote pressure gauge. The water pump runs and automatically adjusts the speed and constant pressure water supply according to the size of the water consumption. If the running water pump reaches the power frequency speed, another water pump will be started for variable frequency operation. When the water pump is supplying water, if the water volume in the tap water network is greater than the flow rate of the pump, the system maintains normal water supply. During peak water usage, if the water volume in the tap water network is less than the flow rate of the pump, the water in the steady flow tank can still supply water as a supplementary source. At this time, air enters the steady flow tank through a vacuum eliminator, and the vacuum inside the tank is damaged, ensuring that the tap water network does not generate negative pressure. After the peak water usage, the system returns to normal water supply state. When the water supply network stops, causing the liquid level in the steady flow tank to continuously decrease, the liquid level detector will feedback the signal to the variable frequency controller, and the water pump will automatically stop to protect the water pump unit. When there is a small flow of water supply at night and the pressure of the tap water pipe network cannot meet the requirements, the pneumatic tank can store and release energy, avoiding frequent starting of the water pump.
