Guangdong electric push rod flameproof electric push rod 1. Overview of electric push rod
The series electric push rod is a general manipulator that converts electrical energy into reciprocating mechanical energy. It is suitable for various complex or simple processes and has a structure It has the advantages of compactness, 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, chemical industry, building materials and other departments.
2. Structure and performance of electric push rod
, structure
The electric push rod consists of motor, reduction gear, screw rod, copper nut, guide sleeve, piston rod, bearing seat, bearing seat, spring , cylinder base, connecting fork and photoelectric proximity switch device (user optional) and other components.
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, and uses the forward and reverse rotation of the motor to achieve push. Rod reciprocates. 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 limit position or the load exceeds a certain value of the rated thrust, the push rod will automatically cut off the power supply and start the operation. It has a protective effect to prevent damage to the motor and other components, but it cannot 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.
1. 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 then passes through the oil circuit. The integrated block is sent to the working cylinder to realize the reciprocating motion of the piston rod.
. When the electro-hydraulic push rod with automatic overload protection function 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 push and pull force within the rated output force range.
, Electronic control can be used to adjust the stroke steplessly within the rated stroke range
According to the rated thrust, electric push rods are currently divided into grades of,,,,,,,,,,,kg, etc., according to The stroke is mm, and each stroke has a speed of or.
