Today, modern life, can be said is the digitization period. Many smart devices have become an integral part of the life of an ordinary person. Amost people forget about simple devices (but not less important used in everyday life. Some people even have a mechanical drive – which the younger generation may regard as a backward technology. Anyway, such devices still exist and can still occupy their place in the latest innovation. This article is for products with linear actuator and accesories and their practical utility.
Linear actuator LA36.
It is possible to call the word “actuator” as “motivator”. Strong enough to hit the vehicle that causes a movement.
When we talk about a actuators and accessories, ie, a device that produces linear motion. The word “motion” can mean different meanings of close/open, raise/lower, push/pull, block/push, etc.
Such mechanisms are widely used in industrial facilities and even in home applications. Everything moving is not possible without a actuators and accessories. Therefore, this product (and accesories) deserves to be a high light title of an important device in our modern life.
Based on the type of power, the Actuators are divided into different types. The classification of actuators depends on the type of energy applied to cause the motion. At now, this mechanism can convert mechanical energy, energy from electricity, air or liquid into motion. The types of actuators have different pros and con. Let’s look at each one separately.
As part of a heating, ventilation and air conditioning (HVAC) system. Damper Actuators control, regulate, control the opening and closing of a control valve (Damper). Opening a valve allows the air from outside a building to allow air to enter, to cool the inside of the building. Or it can close the valve to hold the air inside.
The engine control valve is designed by manufacturers with both electric and pneumatic control. The engine control valve is implemented in the form of spring feedback, rotation, and linear variations. The type of engine that controls the valve is used depending on the type and configuration of the HVAC system in the building.
The purpose of a valve control motor (regulator) allows an HVAC system to deliver outside air. Or move the air system in a way that air can not enter.
An air conditioning system may not be running at the power required to cool the entire space in a building. If the outside temperature is appropriate, the use of outside air will contribute to cost-efficiency improvements. And reduce the pressure on the overall mechanical system. The air that is cooled in the system goes into the building. And the valve control motor can also push the hot air out when the internal air is cooled.
Pneumatic control motors are used. Typically, these valve control motors have a feedback spring for adjusting the actuator, triggered by air pressure changes in the control system. In contrast, the electric control motor is driven by the motor.
Some other types of HVAC control valves include a spring-loaded control motor. As well as a non-return spring motor control device, a suction control motor Fire and Smoke Damper Actuators. Electronic Fail-Safe Actuators are usually controlled by the engine.
straight-drive engines linear actuator in traffic.
Linear actuators (or called: straight-drive engines). The working principle of straight-drive motors is the same as that of conventional rotary motors based on electromagnetic induction. Lorentz force F = qv x B in the linear drive is the force acting on the moving part. Instead of generating the torque in a conventional rotary machine. When the AC current is applied to the primary winding, the magnetic field appears in the gap between the primary and secondary sections.
This magnetic field sweeps through the conductors of the secondary part which results in an electromagnetic induction. The secondary winding should produce an electric current. The magnetic field is applied to the armature current generating the electromagnetic force. Which tends to pull the secondary part running in the same direction from the field. Because a fixed secondary should produce a jet that pushes the primary element in the opposite direction to the magnetic field.
There are three types of actuators and accessories as Short stator type; Long stator; Type stator tooth comb. In the three types, the short stator is used more often. The static part (stator) is no longer meaning but the energy input is the primary and the armature is the secondary. Power cord coils are usually located on the primary side. Synchronous motors are used when magnetic circuits are permanent magnets. More common is the asynchronous linear actuator.
Linear actuators are mainly used in translucent transmissions in vehicles such as locomotives and subways. In some areas of metalworking, crane drive, elevator, compressor, oil well drilling equipment using linear actuators and accessories, etc.
Recently, however, market prices have fallen dramatically. Because of the increasing number of actuators and accessories. Many manufacturers have invested heavily in the production line, the modern equipment for the production of linear actuators.
The number of manufacturers increasing rapidly over the past four years from 4 to 30 manufacturers has created a competitive environment that contributes to reducing the cost of the engine. The actuators and accessories improve very fast. Improvements continue to occur across the entire product range.
