03.Features of water supply equipment

1). Small investment, no need for secondary construction, embedded installation, no stagnant water generated in the equipment, and supply as needed to keep the water quality fresh and alive.

2) Adopting full frequency conversion control, equipped with high-efficiency Siemens dedicated frequency converter, built-in powerful application functions, and a collection of excellent high-performance vector control algorithms, which can control the pump in the best working condition with high efficiency and energy saving, with low power consumption and low operating cost.

3), IP65 outdoor protection level design, comprehensively improve the environmental adaptability, can adapt to various water supply environments; wide voltage design, adapt to the grid fluctuations of about ±20%, no need to worry about the unstable water supply of the equipment due to grid fluctuations.

4) The built-in integrated DC reactor and integrated EMC filter can effectively control the harmonic pollution of the power supply network by the frequency conversion equipment.

5) The equipment can reserve a variety of network communication interfaces according to customer requirements, with strong compatibility and seamless connection with customer monitoring data requirements. The standard configuration adopts a customized IoT communication module, which can realize smart cloud platform mobile APP and computer web management , Control equipment operating parameters anytime and anywhere.

6), configure ultra-clear camera security monitoring system, real-time online monitoring equipment, security, anti-theft, anti-vandalism, automatic alarm capture.

7) The color touch screen man-machine interface is adopted, which is highly intelligent, and the operation is simple and intuitive. It can adjust the water supply according to the user’s water consumption by itself to realize unattended operation.

8) Complete protection functions, complete circuit and automatic protection of water pump, can automatically alarm under abnormal conditions, judge the fault and send alarm information to the user

9) The equipment has the function of estimating flow and energy consumption, and feeds back to the remote interface, without the need to add an additional meter.

10) The Siemens high-efficiency inverter equipped with equipment has perfect frost protection, cavitation protection, and condensation protection, which can effectively ensure the safety of equipment and the stability of water supply

The new generation of WBG type microcomputer frequency conversion direct-connected water supply equipment fully takes into account the special weather in the winter in the north and the rainy season in the south, and specially introduces an outdoor water supply equipment. The microcomputer frequency conversion direct-connected water supply equipment is directly connected to the pipeline, through the constant pressure frequency conversion water supply control system to achieve stable pressure water supply around the clock, adopts the integrated structure design of tank pump, greatly reduces the volume of the equipment, is simple and convenient to install, and is designed as an outdoor type The cabinet is fully considered to be silent, rainproof, moistureproof, dustproof, anti-theft, anti-lightning and other measures to ensure the safe and stable operation of the equipment.
