Piezo Bending Actuators for Piezo Pump Piezoelectric Actuator

Working Principle Piezo Bending Actuators for Piezo Pump:

Piezoelectric pump, micro-pump made of inverse piezoelectric effect of piezoelectric ceramic, no motor, no rotating parts, piezoelectric ceramic piece as its power driving source, piezoelectric ceramic piece is shortened or stretched radially under AC driving. At the same time, the elastic substrate is bent and deformed to form alternating vibration, which causes the pump chamber volume to alternately change. Under the action of the valve, a pressure difference is generated inside and outside the pump chamber to promote the continuous flow of gas or liquid. Because of its small size, light weight, low power consumption, low noise, no electromagnetic radiation and interference, the startup process has no inrush current, no overheating and easy automatic control, so it is a typical low carbon, energy saving and environmentally friendly new type. Fluid equipment and high-tech products are also a revolutionary technological achievement in the field of micro-pumps, and are also a good helper for related industry upgrades.
