Popular Design for TU-1J01 thermal wax actuator for electric switch valve for Kuala Lumpur Manufacturer 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.

The driver or front seat passenger can adjust both air flow and temperature for backseat passengers, by pressing the REAR button and using the front control panel to adjust climate control settings. When you press the REAR button, “Rear” will appear on the display screen.
A second set of controls is located on the ceiling in the second-row. Press the REAR button on the front control panel until “Rear” disappears from the display screen, to allow second-row passengers to use their controls to independently set their air flow and temperature.
Press the AUTO button for automatic cooling or dehumidified heating. The indicator light turns ON when the system is activated. Set it to the desired temperature. It will automatically regulate and maintain fan speed, air flow and temperature for backseat passengers. Press the top FAN SPEED control button to increase or the bottom button to decrease fan speed. Then adjust the temperature using the TEMPERATURE controls. Press the top arrow for warmer or the bottom arrow for cooler air. Press the MODE button to change air flow outlets for the backseat passengers. Press the OFF button to turn off the rear climate controls.
Please see your Owner’s Manual for important safety information, system limitations and additional operating information.

Ultrasonic vibrations generate heat at the location of defects mainly due to frictional rubbing, viscoelastic losses and plastic deformation at the defects.
Vibrothermography is a non-destructive damage detection method in which an external mechanical energy source induces a temperature difference between the defective and non-defective areas of the object’s surface. The temperature difference emits a broad electromagnetic spectrum of infrared radiation which is not visible to the human eye. Thus, the defected area may be detected by an infrared camera through the process of mapping temperature distribution on the surface of the object.
A coupled thermo-electro-mechanical analysis was performed in ABAQUS to simultaneously model the electrical properties of the piezoelectric actuator, the mechanical waves propagating within a plate with three surface cracks, as well as the thermal properties of the plate.
