Description

Technical Field

[0001] This utility model relates to the field of pressure balancing technology, and in particular to an ultrafiltration inlet water pressure balancing device. Background Technology

[0002] By integrating three core modules—intelligent sensing, dynamic decision-making, and flexible adjustment—a highly efficient and stable pressure control system has been constructed. Its core function is to monitor and precisely adjust the inlet water pressure of the ultrafiltration system in real time, ensuring that the membrane modules always operate under optimal conditions. The device employs multi-dimensional pressure sensing technology, which can simultaneously collect inlet water pressure, flow rate, and pulsation data. Combined with a fuzzy adaptive control algorithm, it achieves coordinated control of the electric regulating valve and the variable frequency pump. When pressure fluctuations are detected, the system quickly adjusts the valve opening and pump speed to stabilize the pressure within the set range in a very short time, effectively suppressing water hammer and uneven flow velocity on the membrane surface. The device also features an intelligent energy-saving mode, which can dynamically adjust operating parameters according to actual water demand, significantly reducing system energy consumption. Furthermore, the design of the pressure buffer tank further absorbs high-frequency pressure pulsations, reducing mechanical impact on the membrane modules and thus extending membrane lifespan.

[0003] When in use, if the inlet water pressure is too high during the filtration process, it will damage the ultrafiltration membrane. It is necessary to reduce the water pressure and buffer it. However, the outlet water pressure is low after buffering. Therefore, a balancing device is needed to increase the outlet water pressure.
