Hydraulic Complete Sets, Large-tonnage Cylinders, DT Electric Actuators

The DT series electric push rod is a general-purpose manipulator that converts electrical energy into reciprocating mechanical energy. It is suitable for a variety of complex or simple process flows, featuring compact structure, easy installation, reliable operation, simple maintenance, and energy-saving benefits. Compared to hydraulic and pneumatic systems, it not only eliminates the complex systems and reduces weight but also is not restricted by climate or environment, enabling long-distance centralized or automatic control. It is widely used in industries such as metallurgy, mining, power, coal, transportation, grain, chemicals, and building materials.

Positioning to control the rod's normal start and stop. 2. Electric Rod Structure and Performance:

Structure:

The electric push rod is composed of components such as the electric motor, reduction gears, screw, copper nut, guide sleeve, piston rod, bearing housing, bearing housing, spring, cylinder base, connecting fork, and photoelectric proximity switch unit (optional by the customer).

2. Working Principle:

The motor drives the ball screw nut after being stepped down by a first or second gear, converting the motor's rotational  Dynamic motion transforms into linear motion, beneficial The reciprocating motion of the push rod is achieved through forward and reverse operation of the motor. Output push-pull force is equal. By varying the lever arm lengths, the stroke can be increased.

3. Overload Automatic Protection Function

The power supply will automatically be cut off, serving as a protective measure to prevent damage to the motor and other components; however, this should not be used as a limit during normal operation.

1、Operation Principle: The electro-hydraulic actuator is powered by an electric motor, which, through forward (or reverse) rotation, drives the hydraulic oil to be output as pressure oil through a bidirectional gear pump. The oil then flows through an integrated oil block to the working cylinder, thereby achieving reciprocating motion of the piston rod.

2、Overload Automatic Protection Function: During the operation of the electro-hydraulic push rod, if the external force on the piston rod exceeds the rated output force or the piston reaches the end position, the motor continues to rotate. At this point, the oil pressure in the oil circuit increases to the set pressure, and the overflow valve quickly and accurately overflows, achieving automatic overload protection. Although the motor is rotating, it will not be damaged.

3、Self-locking Function: The hydraulic circuit module of the electro-hydraulic push rod is equipped with a hydraulic self-locking mechanism, ensuring that the piston rod stops immediately upon the motor's shutdown.  At the location, the pressure oil is in a pressure-holding state.

4、Speed can be infinitely adjusted within the designated speed range, as per customer requirements.

5、Continuous infinite adjustment of push and pull force within the rated output power range.

6、The stroke can be infinitely adjusted within the specified stroke range by electrical control.

7、Electric Push Rods are currently categorized by their rated thrust.12 grades, ranging from 25 to 30,000 kg, with travel distances of 100 to 1,300 mm, each with two speeds: 42/84 or 50/100 rpm, and 26.6/53.2.
