The thermal actuators are devices that are mainly utilized for transforming a particular form of energy into motion. A thermal actuator is a kind of non-electric motor that is made up of components like thermal sensitive material and Piston which is capable of producing a type of linear motion in response to the changes in temperature.
Thermal actuator and its uses
Thermal actuators do not require any kind of power source from outside in order to produce motion. In a thermal actuator machine, the temperature directly changes in order to perform some of the predefined tasks like operation of switches, release of latches and opening and closing of valves. Thermal actuators are very sensitive and are used for applications that mainly require actuation at even the slightest temperature changes. These actuators can be utilized for several applications and industries including automotive, aerospace, solar, agricultural industries, HVAC and a few more.
The thermal actuators are most importantly and commercially used in concrete industrial applications. For example, the Aerospace industry utilizes thermal actuators as a safety shut off process, engine lubrication system and fuel control temperature system. This type of thermal actuators are also utilized in the agricultural industry for the livestock watering system, automatic greenhouse ventilation structure, freeze protection and so on.
In the automotive industry, the thermal actuators are utilized as thermostat, transition cooler along with oil temperature regulation application. Thermal sensitive materials utilized in a particular thermal actuator directly respond to the temperature fluctuations, thus causing the thermal actuators piston to move. These materials are basically engineered for expanding with increase in temperature, thus driving the Piston out of the actuator.
How are the thermal actuators manufactured?
The manufacturers produce the thermal actuators in various sizes and options, thus making them an ideal option for various industrial applications. Most of the thermal actuators are mainly designed for the utilization in gas, pressurized or vacuum and liquid environments. These actuators are built out of rugged and durable materials like brass, aluminium, stainless steels and can also be customized as per the industrial requirement. The thermal actuators are machined easily and can be customized or designed to feature any valve end or thread type. Thermal actuator that is made up of good quality metal is resistant to vibration and shock.
Basic features of thermal actuators
Some of the common features that you will found in various thermal actuators include:
- Durable and compact
- reliable than any other actuator type
- unaffected by vibration
- Shock resistant
- works with both gas and liquid
- does not require electricity for operating
- Can be customized as per your product requirement
- reproducible and can be reordered anytime
How do thermal actuators convert the heat energy into the mechanical energy?
The thermal actuators from Suntask have the ability to function quickly and automatically by transmitting the mechanical action after the induction in temperature changes. The mechanical action comes directly from the thermal expansion material which is not affected by the surrounding environment. Thermal actuators have an advantage of adjusting in various temperature ranges and can come under the accurate temperature control system.
The structures of the thermal actuator are very simple and guarantee one with reliable performance. Apart from the industrial application in aerospace and automotive industries, the thermal actuators are also used in sanitization baths, building heating, petrochemicals, solar, water heater, shipbuilding, fire fighting, industrial automatic control, household appliances and others.
