Series electric push rod Shandong Guolong electric push rod Electric push rod Jining electric push rod - Overview of electric push rod:

Series electric push rod is a general manipulator that converts electrical energy into reciprocating mechanical energy. It is suitable for It is suitable for various complex or simple process flows, and has the advantages of compact structure, easy installation, reliable use, simple maintenance, and energy saving. Compared with hydraulic and pneumatic systems, it not only eliminates complicated systems and reduces weight, but is not restricted by climate and environment. It can achieve remote centralized or automatic control and is widely used in metallurgy, mining, electric power, coal, transportation, food, chemicals, building materials and other departments. .

Two electric push rod structure and performance:

Structure:

The electric push rod is composed of a motor reduction gear screw, a copper nut guide sleeve, a piston rod bearing It is composed of bearing seat, spring cylinder seat, connecting fork and photoelectric proximity switch device (optional by the user).

Working principle:

After the motor is decelerated through the first or second stage gear, it drives the screw nut to change the rotational motion of the motor into linear motion, which is beneficial

Use the motor to rotate forward and reverse to realize the reciprocating movement of the push rod. The output push and pull forces are equal. Through various lever arm lengths, the stroke can be increased.

Automatic overload protection function:

The automatic overload protection device in the electric push rod. When the push rod reaches the extreme position or the load exceeds a certain value of the rated thrust, the push rod
/>
The power supply will be automatically cut off to protect the motor and other components from damage, but it shall not be used as a limit switch during normal operation

Therefore, it is required to configure an external travel limit switch device on the machine. Our factory can configure a photoelectric proximity switch device for users to control the normal start and stop of the push rod.
Principle and function
Working principle: The electro-hydraulic push rod uses an electric motor as the power source, and the electric motor rotates in the forward (or reverse) direction, so that the hydraulic oil passes through the two-way gear pump to output pressure oil, and is integrated through the oil circuit The block is sent to the working cylinder to realize the reciprocating motion of the piston rod.
Automatic overload protection function: When the electro-hydraulic push rod is working, if the external force on the piston rod exceeds the rated output force or the piston has reached the end point, the motor is still rotating. At this time, the oil pressure in the oil circuit increases to the set value. Pressure, the relief valve overflows quickly and accurately, realizing automatic overload protection. Although the motor is rotating, it will never burn out.
Self-locking function: A hydraulic self-locking mechanism is designed in the oil circuit integrated block of the electro-hydraulic push rod. When the motor stops, the piston rod immediately stops at a certain position, and the pressure oil is in a pressure-maintaining state.
The speed can be adjusted steplessly within the rated speed range according to user requirements.
Steplessly adjust the push and pull force within the rated output force range.
The stroke can be adjusted steplessly by electronic control within the rated stroke range
Electric push rods are currently divided into three categories according to their rated thrust
