Product Overview:
YMGW non negative pressure household variable frequency water supply equipment for energy conservation and emission reduction is currently a popular trend in China. Our company has developed a non negative pressure water supply equipment based on the variable frequency constant pressure water supply equipment. The non negative pressure water supply equipment fully utilizes the original pressure energy of the tap water network. Under the same water supply demand, relatively small power pumps and control equipment can be selected. At the same time, in the case of low flow water use at night, tap water pressure can be used to directly supply water without starting the pump. Compared to traditional water supply equipment with water tanks, it can save a lot of electricity operating costs and investment costs. Non negative pressure water supply equipment does not require the construction of water tanks or reservoirs, occupying relatively less space, saving initial investment in equipment and the cost of flushing and disinfecting water tanks. The non negative pressure water supply equipment is a fully enclosed structure that truly eliminates secondary pollution in water supply and is a new type of green and environmentally friendly water supply equipment. At present, the commonly used variable frequency constant pressure water supply eliminates surface water tanks and reduces secondary pollution of water quality. However, the cost of constructing and using underground water tanks and the pollution of water quality caused by underground water tanks are also a problem. Therefore, non negative pressure water supply equipment will be the development and extension of variable frequency constant pressure water supply equipment.
The YMGW non negative pressure boosting water supply equipment uses a water pump directly connected to the tap water pipe network, with a pressure regulating tank as the water pump inlet and storage device. A vacuum eliminator is used to eliminate the negative pressure generated in the pipe network. By fully utilizing the tap water pipe network directly connected, a pressure regulating tank is used as the water pump inlet and storage device, and a vacuum eliminator is used to eliminate the negative pressure generated in the pipe network. On the basis of fully utilizing the original pressure of the tap water pipe network, the secondary boosting of the water supply is achieved. This equipment not only achieves the purpose of increasing water supply (without affecting the water of other users in the pipe network), but also saves the investment of water tanks and reservoirs. While ensuring the water quality of the pipe network (without secondary pollution), it can also fully utilize the original water pressure of the pipe network. Its energy-saving effect is extremely significant, reaching more. The non negative pressure water supply equipment is fully automatic and intelligent controlled, with multiple protection and control functions, and can achieve true unmanned operation.
The YMGW non negative pressure variable frequency speed control water supply equipment automatically changes the number and operating speed of water pumps based on the instantaneous pressure and flow parameters in the water supply network, achieving closed-loop regulation of constant pressure variable water supply, thereby improving the company's quality and achieving high efficiency and energy conservation.
Application scope:
1. High rise buildings with water pools, hotels, schools, urban residential areas, enterprises and institutions, and rural living water for new rural construction.
2. Domestic or production water for factories, industrial and mining enterprises.
3. Various types of water plants, water supply stations, sewage and wastewater treatment plants, agricultural irrigation and drainage stations, etc.
4. Centralized hot water supply for high-rise buildings, residential areas, and enterprises and institutions.
5. Pressurization of cooling water and circulating water in production and daily life.
6. Constant pressure oil transportation in oil field pipelines, oil depots, gas stations, etc.
Product features:
1. Significant economic benefits: Multiple advanced technologies are optimized and integrated, and the non negative pressure water supply equipment is directly connected in series with the tap water network, achieving stable pressure, energy saving, hygiene, safe and reliable operation without generating negative pressure, and without the need to build water tanks or reservoirs. It not only reduces the construction period of the project, but also solves the disadvantage of high project cost, and overcomes the shortcomings of large air pressure fluctuations and frequent pump start-up.
2. Sanitary and pollution-free: The equipment is a fully sealed structure, and bacteria and dust will not enter the system; Avoiding the growth of algae, preventing secondary pollution of water sources and water quality pollution issues, users use tap water that meets national hygiene standards.
3. Significant energy-saving effect: The fully enclosed structure operation avoids phenomena such as seepage, running, emitting, dripping, and leaking, without water tanks or pools, saving disinfection and flushing water. Directly connected to the tap water pipeline network can fully utilize the original pressure of tap water, and make up for the difference as much as possible. When the tap water meets the requirements, the equipment will stop working. Non negative pressure water supply equipment operates most of the time at lower frequencies and consumes less power. By adopting frequency conversion technology, further energy saving can be achieved, and the overall energy saving can generally reach more than 50%.
4. Reliable operation: The equipment adopts a frequency converter and high-quality water pump, with complete protection functions and automatic/manual conversion functions, making the operation very reliable. And it has good performance, flexible control methods, and strong anti-interference ability. It has perfect automatic protection functions such as overload, short circuit, overvoltage, undervoltage, phase loss, overcurrent, short circuit, and water shortage. Can perform signal alarm, self check, fault diagnosis, etc. in abnormal situations. When the frequency converter malfunctions, the variable frequency speed regulation water supply equipment can automatically switch to power frequency operation to ensure uninterrupted water supply.
5. Small footprint and easy installation: The entire equipment only has one set of water supply control cabinet and water pump unit, making installation very simple and convenient.
6. Flexible electrical configuration of the equipment: The equipment adopts fully automatic control, PID regulation, keyboard operation, and human-machine interface (text, number) display. Operators only need to switch the electrical control cabinet switch to achieve the desired operating conditions for users, achieving fully automatic unmanned operation.
