ZS(H/G/X) series of intelligent variable frequency water supply equipment technical features

The technology used makes water use more energy efficient

1, Adaptive water supply mode switching technology

In the face of different water inlet pressure changes, the adaptive water supply mode is switched, and the active municipal water supply and water tank water supply are switched, and the passive water inlet pressure and water tank low water level are forced to self-adapt to meet the stable application requirements of water supply equipment in multiple scenarios.

Note: The technology of ZSX series intelligent tank type superposition frequency conversion water supply equipment

2, small flow hibernation and pressure retention technology

Based on the flow prediction model established by relevant conditions such as continuous constant pressure time, running frequency and running current, the system can determine the situation of small flow or unmanned water use in time and carry out active trial and passive mandatory hibernation to achieve the purpose of energy saving. The large-capacity air pressure tank is configured to buffer the hammer force while increasing the pressure holding time, reducing the frequent start and stop times of the pump to further achieve energy saving and consumption reduction.

3, vector full frequency anti-shake control technology

One-to-one vector frequency conversion operation, multi-level backup, intelligent soft switching, full flow speed regulation, independent analysis of energy consumption data, automatic inspection of low-frequency status, automatic adjustment and optimization of equipment operation mode; It can effectively alleviate the fluctuation of the power grid during the start and stop of the pump frequency, and can obtain instantaneous power saving; At the same time, the pressure in the process of increasing and decreasing the pump is smooth and the jitter is reduced, so that the user experience is better.

4, full frequency segment efficiency balancing technology

Based on the selection software, the optimal pump selection is determined, the optimal flow range of the pump is analyzed, and the pump curve is introduced. The frequency and torque closed-loop control under the dual DSP architecture, adaptive control characteristics, VF multi-point control speed regulation are adopted, and efficiency optimization is carried out by fuzzy algorithm to achieve constant torque safe operation and energy saving and consumption reduction of multiple pumps.

 2, high-precision instrument

Using the international brand pressure sensor + pressure switch of electrical and mechanical combined pressure protection, the ultimate pressure capacity of more than 10MPa effectively prevents water hammer impact, and the detection accuracy of more than 5%o effectively ensures the stability of water supply operation.

 3, high strength base

The base of the high-strength channel steel frame structure is constructed with vertical and horizontal support beams up and down and left and right, and through the manufacturing process of full overlap splicing and full welding of the contact line, the use strength is ensured, and the weight of the water supply equipment can be borne more than 5 times for a long time to ensure no bending deformation.

 4, high standard technology

After mirror polishing and other surface modification of the pipeline, the grain refinement is achieved, the surface roughness Ra is less than one thousandth of the hair, and the fatigue life is several times higher than that of similar products. Laser cutting + fish scale automatic pipeline welding, single-side welding double-side molding process to ensure product quality reliability and stability.

 5, high protective shell

Semi-clad sheet metal cover, with hidden cable layout, the overall structure is more compact, and the protection of the core device is more effective.
