Hot New Products TU-1C05 thermal wax actuator for thermostatic automatic water drain valve Wholesale to Argentina 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.

A space robot that has a manipulator arm mounted on a satellite body was conceived to perform various tasks for construction and maintenance of space structures. For such activities, control strategies need to be developed such that a space robot can change its orientation and articulated shape readily. External force actuators consume fuels that are limited in quantity and expensive. It is pragmatic to minimize the usage of the external force actuators to maximize the useful life span of the space robot. In the absence of external forces, the angular momentum of a space robot is conserved.
This imposes a nonholonomic constraint on the motion of a space robot. In situations where the space robot maintains zero momentum, it is possible to control the attitude of the space robot using the motion of the manipulator mounted on the main body and without using the external force actuators. This has motivated researchers to address the control problem of a space robot without external forces.
