Good User Reputation for TU-1D091 thermal wax actuator for industrial thermostatic water regulations mixing valve to Paris Factory 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.

Alright, today on Repairs101 I thought I’d go over the basics of how your car’s cooling system works.
So an engine’s primary function is to produce power or motive force and one of the by products it creates as a result is heat.
So the system developed to extract heat is fairly simple. A fluid – mostly water – is run through the passages and galleries in the engine. Then when the fluid reaches temperature, it’s released into the radiator. There it exchanges heat with the relative wind from forward momentum or by the air forced over the radiator by a fan.
Now the heart and the brains of the cooling system, respectively, are the water pump and the thermostat.
The water pump is usually found on the front of an engine, belt driven and used to circulate coolant from the engine block to the radiator.
The thermostat is an automatic valve that opens when the water inside the engine hits a predetermined temperature. When it opens the coolant flows until the fluid inside the engine is cool enough to shut the thermostat again.
Now the radiator is a fluid – air heat exchanger that has tiny passages in it with large surface areas exposed to the cool air.
You can test your cooling system by pressurizing it cold with a pressure test kit. You can see the fluid escaping as I release the pressure – so never open a hot rad cap because the heat tells you it’s under pressure.
Now the cap has two functions – one, to seal the system so it will pressurize when it’s heated – and two, to blow off excess fluid due to thermal expansion when it becomes over-pressurized.
In the old days the coolant would just dump out onto the street. Modern designs will catch the fluid from the overflow tube, and redirect it into an expansion tank where it will be collected and then drawn back into the system as it cools off.
Alright thanks for watching and hey! Don’t forget to subscribe!
