DV/DVS/DVL series non-negative pressure variable frequency water supply system

Product Introduction
Dayuan Pump Industry's DV/DVS/DVL series non-negative pressure variable frequency water supply system is the latest generation of fully automatic pipe network superimposed pressure water supply equipment, which consists of a vertical multi-stage pump unit, a variable frequency control cabinet, pipeline valve accessories, a pressure tank and a non-negative pressure flow stabilizing tank. According to the fluctuation of the outlet water pressure, the control system automatically starts and stops the equipment and performs variable frequency control to achieve stable constant pressure water supply. The non-negative pressure water supply equipment is connected to the municipal water supply network, mainly used to eliminate the impact of insufficient water supply in the municipal pipe network and ensure safe, stable and reliable tap water supply.

Features

1. Energy saving and environmental protection, the system is directly connected to the municipal water supply network, making full use of the network pressure and reducing the system configuration power. According to the immediate water demand, the closed-loop control adjusts the operation of the pump group to accurately save energy; 2. The output network pressure is stable, and the water supply equipment is composed of frequency conversion components to form an automatic closed-loop control. The pressure regulation and recovery accuracy is within 0.5 seconds, avoiding sharp pressure fluctuations during water use; 3. Complete water supply functions and high insurance factor. When a sudden failure occurs in the running pump group, the equipment will intelligently start the backup pump to continuously supply water. The system has a high fault tolerance rate and ensures uninterrupted water supply; 4. The non-negative pressure water supply equipment can flexibly customize the pump group, pipeline, and frequency conversion control equipment according to the user's flow, head, budget and other requirements to meet the use needs in a humanized way; 5. The equipment has negative pressure elimination and water shortage protection
