The Working Principle of Electric Actuator

Source:http://www.flowxgroup.comUpdate Time:2014-10-15Hits:

There are several parts that decide the electric actuator working principle. And each part has a direct influence on the performance of the electric actuators. Therefore, it is necessary to lay emphasis on the operation and maintenance of these components.

The first component which influences the electric actuator working principle is electric motor. The electric motor possesses high starting force moment, low starting current as well as small rotation values, which makes electric actuator possess favorable servo feature. There is thermal switch inside of electric motor to function as thermal protection. If there is strange overheat of the electric motor, it is possible to power off the switch that controls the circuit of the electric actuator so as to protect electric motor and electric actuators. After cooling the electric motor, the switch can be power on and the circuit is able to work again. In order to get over with inertia coasting operation, there is electric braking function of the control circuit of adjustment electric actuator.  

Another component that decides the performance of the electric actuator working principle is the reducer. And angular journey electric actuator uses planet reducer together with worm gear operated device, which possess higher mechanical effects as well as mechanical self-locking feature. And sliding stem electric actuator is composed of multiple turn electric actuator reducers and feed screw nut. And there is also moment stroke limiter, which is a standard unit set inside of reducer, composed of over moment protection part, journey control part as well as position sensor and amphenol connectors.

The over moment protection part is one of the important component that decides the electric actuator working principle. The planet gear is able to produce deflection in the middle of delivering moment and set in the rocking beam outside of the gears. And there are sensing elements on both sides of the rocking beams to measure compression spring. And when output moment exceeds set limited moment, the deflection of the inner gear makes rocking beam touch force moment so as to cut off the control circuit to stop electric motor. Another component that decides the electric actuator working principle is switch control pneumatic actuators, which possesses a electric locator inside of it. And in the middle of dealing with problems and debugging, it is possible to operate through handles.

The electric actuator itself is a kind of fitting to be equipped on some machines. Therefore, it is possible to make sure the performance of electric actuator so as to make sure the performance of any machines. And in order to guarantee the performance if the electric actuator, it is possible to understand the electric actuator working principle. Therefore, all of above components should be paid much attention to.
