Domestic Water Supply Cabinet

The Domestic Water Supply Cabinet is a water supply control device specially designed for residential complexes, commercial buildings, hotels, and other civilian applications. Its core purpose is to ensure stable pressure and a continuous supply of potable water. Unlike control cabinets for clear water pumps in industrial settings, this model emphasizes user-friendliness and energy efficiency. Its key advantages are as follows:

• Constant Pressure Water Supply Control: Equipped with a pressure sensor and a variable frequency drive (VFD) module, it continuously monitors pipeline network pressure and automatically adjusts pump speed. This ensures stable pressure (e.g., maintaining 0.3-0.5MPa) during both peak and low water usage periods, preventing fluctuations in tap water flow and improving the user experience.

• Multi-Pump Rotation & Energy Saving: Supports the alternating operation of 2 to 6 pump units. It automatically adjusts the number of running pumps based on water demand (e.g., one pump during low demand, three pumps in parallel during peak hours). Simultaneously, energy consumption is reduced via VFD speed control, achieving 30%-50% energy savings compared to traditional fixed-speed water supply systems.

• Dry Run Protection & Alarm: Fitted with a level sensor to monitor the water level in the storage tank or sump. When the level falls below the set point, the system automatically stops the pumps, triggers audible and visual alarms to prevent dry running damage, and can interface with a water replenishment system to ensure an adequate water source.

• Quiet & Safe Design: The cabinet is lined with sound-dampening materials to reduce operational noise (≤55dB), making it suitable for residential environments. It also features overload, phase-loss, and leakage protection functions, complying with civilian electrical safety standards (e.g., GB 16895.21-2011) to ensure user safety.
