Changsha constant pressure water supply device manufacturers are expected to stop falling and stabilize and further develop


The world today is facing unprecedented changes in a century, the world economy is slowing down, trade protection is intensifying, and the digital economy has a significant impact on globalization. The sustained development of China's domestic economy faces both risks and challenges as well as rare opportunities. China's huge market advantage, the strength of reforms to adapt to changes, and the unique advantages of the system are the greatest strengths for China's sustainable economic development.
Although the domestic constant-pressure water supply equipment industry has maintained steady development against the backdrop of a complex and volatile external situation, it still faces many difficulties and challenges are still severe. The industry ’s economic operation is stabilizing, slowing, and worrying. The problem has not yet been resolved. In the future, the Changsha constant pressure water supply device industry will accelerate the transformation and upgrading, and supplement the shortcomings with the core of independent innovation, so as to achieve high-quality development.
The industry predicts that the growth curve of domestic constant-pressure water supply installations this year will show a downward trend and then an upward trend. As long as the kinetic energy conversion is speeded up, the Changsha constant pressure water supply device will definitely turn from danger to opportunity and become stronger.
Features of constant pressure water supply device
1.No need to set up reservoirs and high-level water tanks
The constant-pressure water supply device is directly connected to the municipal pipe network without the need to build a reservoir and a high-level water tank, saving engineering investment and reducing the occupation of building area. When the water supply of the municipal pipe network is sufficient, the volume of the non-negative pressure steady flow tank is small, the entire equipment occupies a small area, and the installation of the equipment only needs to connect the inlet and outlet pipes, which is extremely convenient.
2.Secondary pollution without water source
The non-negative pressure steady flow tank and the entire set of equipment pipelines are all closed. From the municipal pipe network to the user's faucet, they will not be contaminated by debris and dirt in the air. The flow part is treated with anticorrosive coating on the inner wall of the food container. The coating and the constant pressure water supply device are in compliance with relevant food hygiene standards.
3. Significant energy saving effect
The traditional secondary pressurized water supply method uses a storage tank and a high-level water tank. When the water supply pressure of the municipal pipe network is put into the storage tank, energy loss is exhausted and energy is wasted. After adopting a non-negative pressure steady flow tank, the water supply pressure of the municipal pipe network is directly superimposed on the inlet of the feed pump. The water pump only needs to supplement the insufficient part of the municipal pipe network pressure, and the energy saving effect of the whole machine is significant.
4.No need to set pressure regulator pump and large volume air tank
In general, frequency conversion water supply equipment is designed to ensure that the user does not frequently start the water supply pump when leakage of small flow water or zero flow into the pipe network at night. They are equipped with a low-pressure pressure-stabilizing pump and a large-capacity air pressure tank. Sexual investment has also increased the operating costs of the equipment (the power consumption of the evening pump operation).
During the low water peak periods such as at night, the water supply pressure and water supply volume of the municipal pipeline network can basically meet the user's requirements. After using the non-negative pressure steady flow water supply equipment, the original pressure of the municipal pipeline network is fully utilized. Water is directly supplied to the user. The equipment does not require a device pressure stabilization pump and a large-capacity pressure-controlled pressure tank, which saves investment and significantly improves the energy-saving effect when the device is running.
Application range of constant pressure water supply device
Suitable for water supply in any area with insufficient tap water pressure
