Summary of non negative pressure water supply equipment
Non negative pressure water supply equipment is no negative pressure water equipment technology development department of scientific research personnel of the company for the new system, in order to solve the traditional living water supply system, the development and the negative pressure pump is directly connected to the tap water pipe network, model WFGW, WFJY series of non negative pressure water supply equipment (network regulation pressurization equipment). This product not only solves the problem of pollution two underground pool, also can be matched with pure water equipment, direct drinking water equipment as a booster, can be used in any a pressurized pipe network in water supply system. The series of products to obtain a number of utility model patents.
Characteristics of non negative pressure water supply equipment
1, Electricity saving and water saving
Soft starting with frequency conversion, the current impact is avoided. At the same time, the realization of constant pressure control, but also to avoid the impact of the pipe network, to extend the life of the pipeline and the valve. The traditional water tank two times the water supply mode to put the tap water into the pool, so that the original tap water is zero, and the original pressure energy of the tap water is wasted.
The device is connected with the tap water pipe network to make full use of the pressure energy of the pipe network, and the electricity saving can reach 50% ~ 90%.
2, Eliminating the two pollution of the underground water tank
The traditional pool two pressurized water supply will tap water into the tank, the tank water is contaminated by dirt or animal body, especially in the summer easy to produce algae or mosquitoes directly affect the health of users. The device uses a closed type water supply mode to eliminate the two pollution.
3, Save investment, reduce the occupied area, installation, use, maintenance convenience
Construction of the pool, the total investment of the project, and the use of the process to be cleaned regularly, not only increased the total investment of the project, but also increased the cost of daily maintenance. The device is used for regulating the water supply of the device, saving investment and reducing the occupied area, according to the situation of the user, the vertical or horizontal type of different installation methods can be adopted, and the maintenance is convenient.
4, Using PID closed loop adjustment, constant pressure and high precision, small fluctuations in water quality.
5, With overload, short circuit, over current and other automatic protection function.
6, High degree of automation, reliable operation, convenient management.
Non negative pressure water supply equipment system schematic
Non negative pressure water supply equipment model
1, The microcomputer set to the water pump working pressure, that is, the user water pressure. Living water supply, equipment operation at low frequency by frequency, time monitoring network pressure on the feedback value and the set value calculation and comparison of calculation, if the pressure is higher than the network user required pressure (set pressure) will automatically reduce the output frequency, so that the pump speed is reduced, to reduce the amount of water. If the pipe network pressure is lower than the user's pressure (set pressure) will automatically increase the output frequency. In order to increase the speed of the pump, the output increase, when a pump can not meet the needs of users, the other pump automatic input, to ensure that the user's use of pressure.
2, When the pressure reaches the tap water pipe network and the user use pressure when inverter after a long time after reducing speed until the shutdown, only when the pressure down to a set pressure value, the inverter will start work again. Variable frequency pump group work is only to meet the user's water pressure and the pressure of the pipe network, greatly saving energy.
3, When the flow regulator pressure below atmospheric pressure, opened in the installation of automatic flow regulator top pressure canceller, the gas into the flow regulator, eliminate the negative pressure. When the pressure in the flow regulator is increased, the excess gas can be discharged out of the flow regulator, so that the flow regulator is filled with water to be used for the next peak time. When the flow regulator is filled with water after the installation of automatic closing in flow regulator top pressure canceller, prevent overflow.
