professional factory provide TU-1J02 thermal wax actuator for electric switch valve for UAE Importers 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.

I have gotten reports that a 79.5 inch belt is quieter, and better fit. In this video we fix a broken belt and bypass the AC compressor with the new serpentine belt. Very simple, no special pulley or parts required. 4.6 & 5.4 L. F150 expedition. You can do it in minutes!
This video shows the first micro comb-drive actuator experiment in Thailand performed on Tuesday 19 th January 2010. This electrostatically driven micro comb-drive actuator had a suspended rotor comb with 19 fingers each of which was 30 microns in width. The stator comb with same dimensions was anchored to the substrate. The main structures of both rotor and stator combs were made of 300 micron-high SU-8 polymer followed by metal coating by sputtering technique. The patterning of this actuator was done by synchrotron x-ray lithography at micromachining lab, the Synchrotron Light Research Institute, Thailand by Winai Wanburee, a graduate student from the Suranaree University of Technology (Ph.D. program in Electrical Engineering). In this first driving experiment, DC pulses of 1 Hz with various amplitudes were fed into the rotor comb while the stator comb was grounded. This experiment showed an important milestone for MEMS community in Thailand.
