DKJ-410 DKJ-510 Electric rotary actuator

Overview of DKJ-410 DKJ-510 Electric rotary actuator

DKJ angular stroke and DKZ straight stroke are the earliest and only electric actuators produced in my country. They are products designed by the country during the planned economy period in China.

Our engineers participated in this work at the earliest and made contributions to the launch of DKJ and DKZ products, and also laid the foundation for the professional development direction of the company. This product is used by the earliest large state-owned enterprises because of its simple structure, economical and practical advantages.

With the development of modern industrial computer management, today, our DKJ and DKZ series have two substantial improvements compared with the previous ones: Produce intelligent electronic type, outdoor type, flameproof type, etc. that are directly controlled by computer Improved productThe circuit control part is encapsulated in a small plastic box, commonly known as a module, forming a plug-and-play type that is easy to maintain, with higher adjustment accuracy and longer service life.

Our products are the most standard appearance and installation dimensions, and have played a role in the renovation projects of many large enterprises.

Working principle of DKJ-410 DKJ-510 Electric rotary actuator

DKJ, DKZ series electric actuators are terminal control devices of industrial process measurement and control systems, which can convert the control signals of the system into angular displacement and linear displacement of the output shaft, control the position of valves and other closing parts or other adjustment mechanisms, so that the The controlled medium works according to the state specified by the system.

Electric actuators are divided into proportional and integral types according to control methods. The proportional actuator is composed of an electric servo amplifier and an integral actuator, which can compare the control signal of the system with the feedback signal about the position of the output shaft (closed-loop control) to change the stroke of the output shaft and make it proportional to the output signal relation. The integral actuator is composed of a servo motor, a reducer and a position transmitter. It can cooperate with an electric operator to realize remote operation of valves or other adjustment mechanisms.
