Factory Promotional TU-1D091 thermal wax actuator for industrial thermostatic water regulations mixing valve to US Factories Detail:
1. Operation Principle
The Thermostatic Wax that has been sealed in shell body induces expansion by a given temperature, and inner rubber seal part drives its handspike to move under expansion pressure to realize a transition from thermal energy into mechanical energy. The Thermostatic Wax brings an upward movement to its handspike, and automatic control of various function are realized by use of upward movement of handspike. The return of handspike is accomplished by negative load in a given returned temperature.
2. Characteristic
(1)Small body size, occupied limited space, and its size and structure may be designed in according to the location where needs to work.
(2)Temperature control is reliable and nicety
(3)No shaking and tranquilization in working condition.
(4)The element doesn’t need special maintenance.
(5)Working life is long.
3.Main Technical Parameters
(1)Handspike’s height may be confirmed by drawing and technical parameters
(2)Handspike movement is relatives to the temperature range of the element, and the effective distance range is from 1.5mm to 20 mm.
(3)Temperature control range of thermal wax actuator is between –20 ~ 230℃.
(4)Lag phenomenon is generally 1 ~ 2℃. Friction of each component part and lag of the component part temperature cause a lag phenomenon. Because there is a difference between up and down curve of traveling distance.
(5)Loading force of thermal wax actuator is difference, it depends on its’ shell size.

Test of 7 piezo electric bimorph cantilever beam actuators at 1 Hz, 0-300V. These are wired in parallel and held with ceramic tweezers to prevent shorting.
The bimorph actuators are a laminate consisting of three layers: the top layer is PZT, the middle layer is carbon fiber, and the bottom layer is PZT. They can be thought of as two capacitors in series; on the top side, the PZT-to-carbon fiber represents one capacitor, while the carbon fiber-to-PZT represents the second capacitor on the bottom side. The ‘directionality’ or poling of the PZT depends on the manufacture of the PZT material – meaning that the electric field applied to them should always be in the direction of their alignment (you can’t simply put an AC waveform to them). These actuators are configured to run in “simultaneous drive”, which means that the top-most surface of the top PZT layer is charged at a constant ‘bias’ voltage, the bottom-most pzt surface is held at ground potential, and the carbon fiber layer is given a varying signal in this case a 1Hz sinusoid from 0V to 300V. This arrangement ensures that the signal applied to each ‘capacitor’ unit is always positive. For example, if at one moment the ‘bias’ was 300V and the and carbon fiber was at 150V, then each capacitor would be strained the same amount and the actuator as a whole would be in a neutral position. On the other hand, if the bias was 300V and the carbon fiber layer was held at 50V, then the top PZT would be more strained than the lower PZT, causing the actuator to deflect. In both cases, the polarity of each ‘capacitor’ is respected. There are different types of arrangements for driving actuators, such as the ‘alternating drive’ topology.
