Water supply method

The traditional water supply method adopts the combined water supply method of the underground water pool and the water pump, that is, the water supply from the municipal external network to the underground living pool, and the use of the water pump to meet the water pressure. Although this solution can satisfy the stability of water supply pressure and the reliability of water supply, all the tap water is put into the water tank, and then the water is pumped to the water tank to supply water to the user through the secondary pressure of the water pump. The original pressure of the tap water cannot be used, and the system power consumption Large; troublesome installation and maintenance.

No negative pressure frequency conversion water supply program uses frequency conversion without negative pressure pipe network Pressurized steady flow water supply method, no need to build a pool and add a water tank, the second pressurized water supply can be directly connected in series on the tap water pipe network, closed type steady flow compensator And vacuum suppression and compensation system, the use of microcomputer control, automatic adjustment, so that the water pipe does not produce negative pressure. Therefore, the new program will not only not affect the surrounding users of water, but also can take full advantage of the pressure of the tap water to achieve the purpose of energy saving, in addition to eliminate a series of ills caused by the construction of the pool.

Constant pressure water supply

Water quality

The main link in the secondary pollution of drinking water is the pool and tank that are used in the secondary pressurization system. Because pure tap water is put into a pool or a water tank, various impurities and contaminants can easily enter the water. Especially in the summer, the water quality can easily deteriorate and become bad, which seriously pollutes the water source and affects people's health. In addition, improper selection of materials or anticorrosion of the pool or tank will also directly pollute the water.

The non-negative pressure frequency conversion water supply equipment does not have any intermediate adjustment device, no underground living water tank and high water tank, and it is a fully closed system, eliminating the main part of secondary pollution and ensuring the water quality safety in the water supply system. At the same time, the equipment itself has undergone anti-corrosion treatment or uses stainless steel high-quality materials to completely eliminate the secondary pollution in the secondary pressurized water supply system and ensure the user's water supply security.

control method

No negative pressure frequency conversion water supply equipment has over-voltage, over-current, overload, non-water alarm and other protection functions. The equipment fully simulates human brain intelligent technology to fully control the equipment, a high degree of automation; but also according to user needs Remote monitoring and monitoring system realizes 24-hour real-time monitoring of equipment. It also assists users in establishing a centralized monitoring center to monitor the current, voltage of the pump, the pressure of the inlet and outlet pipes, and the frequency of the water pump. Once an abnormality occurs, the equipment will immediately report an alarm. Soft faults can be eliminated through remote monitoring; in addition, the start-stop of devices can also be remotely controlled in the monitoring center.

Investment situation

The non-negative pressure frequency conversion water supply equipment can be directly connected to any pipe network with insufficient tap water pressure for pressurized water supply. There is no need to build a tank for water tanks, and disinfection equipment that has been invested due to secondary pollution can also be omitted. The cost of constructing structures such as tanks for water tanks and the cost of disinfecting the secondary pollution of water are saved, ranging from tens of thousands to as many as 100,000.

Energy Analysis

The traditional water supply design plan puts tap water into the groundwater pool. The pressure of the original municipal pipe network becomes zero, and the water supply points are repressurized from scratch. The original water supply pressure of the tap water is wasted. There is no negative pressure water supply equipment directly connected to the water pipe network. It can fully utilize the pressure of the water supply pipe network and adopt frequency control. The motor pump of the equipment is controlled under the control of the microcomputer and adjusts the speed of the motor according to the pressure of the tap water. When the tap water meets the requirements, the equipment stops working, and the tap water is directly supplied to the user. Compared with other water supply equipment, the electricity saving can be up to 50% to 90%.
