Introduce:
(1) Equipment definition and working principle
Equipment definition: Non-negative pressure water supply equipment, also known as network superimposed pressure water supply equipment, is one type of secondary water supply equipment. It directly connects to the municipal pipeline network and conducts secondary pressurization on the basis of the remaining pressure of the municipal pipeline network to meet the water supply demands of users, while ensuring that the pressure of the municipal pipeline network is not lower than the set value.
Working principle: The equipment forms a regulation mechanism through frequency converters, pressure gauges, regulators, etc., and an execution mechanism through devices such as circuit breakers and contactors, jointly achieving water supply. When the water supply volume of the municipal pipeline network exceeds the water consumption of users, the equipment provides variable frequency constant pressure water supply. When the user’s water consumption increases and the pressure drops, the equipment eliminates the negative pressure through a vacuum suppressor to ensure stable water supply.
(2) Equipment composition and Classification
The equipment composition: The non-negative pressure water supply equipment mainly consists of a constant flow tank, a vacuum suppressor, a variable frequency speed regulation water pump unit, a pressure sensor, a variable frequency control cabinet, etc. These components work together to ensure that the equipment can operate stably and efficiently.
Equipment classification: There are mainly two types of non-negative pressure water supply equipment in the market: tank-type non-negative pressure water supply equipment and box-type non-negative pressure water supply equipment. They are selected based on specific application scenarios and requirements.
Advantages of the equipment:
1.Energy-saving and highly efficient: The equipment fully utilizes the original pressure of the municipal water supply network and saves energy through the superimposed pressure water supply method. Meanwhile, the equipment is equipped with an intelligent regulation function, which can automatically adjust the water output according to the user’s water consumption, achieving high efficiency and energy conservation.
2.Pollution-free: The equipment adopts a fully enclosed water supply method, without pools or water containers, thus avoiding the problem of secondary water pollution.
3.Low investment and small land occupation: No need to build water tanks or water storage boxes, saving construction costs and later cleaning and maintenance costs. Meanwhile, the equipment takes up a small area, providing users with more possibilities for space utilization.
4.High automation: Reliable operation and convenient maintenance; The equipment features a high degree of automation and reliable operation.
