JINYU BRAND DG Electric Linear Actuator ACCEPT OEM
DG Series Electric Linear Actuator
An electric linear actuator is also known as an electric cylinder or linear actuator. As early as in the 1980s, it was introduced into China and was used in steel mills and power plants. Our company was one of the earliest enterprise that engaged in developing and producing of this product series in China. Its rationale is to translate motor’s rotary motion into linear actuator’s linear motion so as to realize remote, centralized or automatic program control and automatic reciprocating movement. The product is compact, safe and reliable. In recent years, the scope of application has been increasingly expanded, reaching out to almost all equipment of reciprocating motion.
An electric linear actuator (i.e., electric linear actuator), is a kind of drive gear that converts rotary motion of a motor to linear motion of a linear actuator in order to realize remote, centralized or automatic control program.
Push and pull force (N); Travel(mm); Speed (mm/s).
- Components: Motor, reduction gear, screw, linear actuator, and electrical control system.
- Structure type: Motor vertical to linear actuator; Motor parallel to linear actuator; Motor and linear actuator are coaxial.
- Drive motor type: Common three-phase asynchronous motor; common two-phase motor; common DC motor; variable frequency motor; DC servo motor; stepper motor and so on. Pneumatic and hydraulic motors can also be used to meet some special requirements.
- Functions: Turning on/off, moving up/down, tilting, conveying, flipping, stop, positioning, and intermittent transmission, etc.
- Application: Metallurgy, mining, electric power, petrochemical, coal, machinery, transportation, shipbuilding, environmental protection, building materials, construction, aerospace, aviation, national defense and other industries.
- Main parameters for model selection:
II. Operation monitor and control type
1. Contact switch (mechanical) 2. Magnetic induction switch 3. Potentiometer 4. Optical grating counter
III. Operation control parameters
1. Fixed speed control; Select fixed speed from model selection table, invariable.
2. Step less speed control: Speed can be adjusted at will through frequency conversion or servo motor.
IV. Selection instructions
First, identify the motion state of the object, carry out force analysis, and calculate push force, travel and speed, and then select linear actuator model from selection table to meet these three parameters. If push force and travel fall short, a lever mechanism may be added to change the arm of force, or place tailor-made order. We are ready to design and manufacture specifically for you what you really need to ensure your satisfaction.
V. Installation instructions
Electric linear actuator housing is equipped with fulcrum bars for installation. A chassis or hanging bracket may be installed in proper position, the shaft extension shall be coupled with driven components. Installation chassis and other accessories can be ordered at your option.
1. The overload protection switch of electric linear actuator must be concatenated to the motor control circuit.
2. In operation, an external travel limit switch must be installed to control the electric linear actuator. Overload protection switch shall not be used as external travel switch. External photoelectric proximity switch can be ordered at your option.
3. Normal electric linear actuators are not allowed to bear radial force in installation and use.
VI. Maintenance and repair
1. Working temperature -15 °C〜40° C, relative humidity< 85%.
2. Maintenance and repair shall be made at regular intervals of running (about six months). To grease the screw, remove the oil plug on the cylinder, make the linear actuator travel forward, then spread grease on the screw with a grease gun. To grease gear and bearing, removable cover plate of the gear box, directly add grease on them.
3. Always pay attention to the position limit switch for fear of its displacement and out of control in multiple use, which may cause motor burned.
