D electro-hydraulic push rod
D electro-hydraulic push rod is a hydraulically driven manipulator that integrates mechanics, electricity and hydraulics. It is suitable for reciprocating push-pull linear (or reciprocating rotation at a certain angle) movements. It can also be used for Places where work needs to be raised, lowered or clamped, and centralized or automatic control of remote dangerous areas can be achieved. It has been widely used in metallurgy, mining, electric power, coal, machinery, transportation, food, chemical industry, cement, water conservancy, building materials, transportation and other departments as a universal power source.
Working principle of D separated electro-hydraulic push rod
The electro-hydraulic push rod is a new type of flexible transmission mechanism integrating mechanical, electrical and hydraulic. It consists of an actuator (cylinder) and a control mechanism (hydraulic control valve). Group) and power source (oil pump, motor, etc.). The electro-hydraulic actuator can have a variety of structural forms according to the on-site installation space and user usage conditions (see the electro-hydraulic actuator outline and dimension diagram for details, and the style can be customized according to user requirements). The electric motor drives the bidirectional hydraulic pump through forward and reverse rotation, and the pressure oil is sent to the cylinder through the hydraulic control valve to realize the reciprocating motion of the piston rod.
The working characteristics of D electro-hydraulic push rod D electro-hydraulic push rod Design oil circuit combination valves with different functions to meet their working requirements. The hydraulic control valve group is mainly composed of a relief valve, an oil suction check valve, a speed regulating valve (user requirements), a hydraulic control check valve (hydraulic lock), etc. It generally has push-out self-locking, pull-back self-locking, and both push-pull and push-pull self-locking. The operating speed is adjustable. The working angles of speed-type non-adjustable electro-hydraulic push rods include horizontal push and upward push (including diagonal upward) and downward push (including diagonal downward).

D separated electro-hydraulic push rod has the following main advantages
It can be started with load and has overload protection function.
The circuit is equipped with a two-way hydraulic lock that can stop at any position within the specified stroke range and self-lock while keeping the output force unchanged.
Push and pull force speed (user requirement) is steplessly adjustable and the driving force range is extremely wide.
If the power is cut off for some reason, the push rod will lock itself to avoid accidents.
Compact structure, easy installation, small space occupation and simple maintenance.
Adopt full hydraulic transmission for sensitive action and smooth operation, which can effectively buffer external impact force and precise stroke control (.)
Electromechanical and hydraulic integrated fully enclosed structure, the working oil circuit circulates in a pressureless closed steel cylinder and is small in size. Oil leakage, no dust collection, no water ingress, no internal corrosion, long service life in harsh working environments.
Working principle:
The electro-hydraulic push rod uses an electric motor as the power source and rotates in the forward (reverse) direction of the electric motor, so that the hydraulic oil outputs the pressure oil through the two-way gear pump and is sent to the working cylinder through the oil circuit integrated block to realize the piston rod. reciprocating motion.
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, and the oil pressure in the oil circuit will increase to the set value. The pressure relief valve quickly and accurately overflows to achieve automatic overload protection. Although the motor is rotating, it will never burn out.
Self-locking function
A pressure self-locking mechanism is designed in the oil circuit integrated block of the electro-hydraulic push rod. When the motor stops rotating, the piston rod immediately stays in a certain position and the pressure oil is in a pressure-maintaining state.

D: electro-hydraulic: separate push rod: explosion-proof
Selection instructions
Electro-hydraulic push rod It is mainly composed of six basic elements such as the type of push rod, motor protection level, rated output force, stroke, rated speed and angle of use. It can also be based on the special requirements of users.
D () type electro-hydraulic push rod means that the split electro-hydraulic push rod requires the motor to be explosion-proof and its maximum thrust stroke and maximum speed/.
