1、 Overview of electro-hydraulic push rods:
DYT series electro-hydraulic push rods are a hydraulic driven robotic arm that integrates mechanical, electrical, and hydraulic functions. They are suitable for reciprocating linear motion (or reciprocating rotation to determine the angle), and can also be used in places where objects need to be lifted, lowered, or clamped. They can also achieve centralized or automatic control in remote hazardous areas. It has been applied in sectors such as metallurgy, mining, electricity, coal, machinery, transportation, grain, chemical industry, cement, building materials, transportation, etc., and is a universal power source
2. Working principle and structural performance of electro-hydraulic push rod:
1. Working principle:
Electric electro-hydraulic push rod is a flexible transmission mechanism that integrates mechanical, electrical, and hydraulic systems. It consists of an actuator (oil cylinder), a control mechanism (hydraulic control valve group), and a power source (oil pump motor, etc.).
. According to the on-site installation space and user usage, the electro-hydraulic push rod can have various structural forms (see the external installation dimension diagram of the electro-hydraulic push rod for details, or customize the style according to user requirements). The electric motor drives the bidirectional hydraulic pump to output pressure oil in both forward and reverse directions, which is sent to the oil cylinder through the hydraulic control valve to achieve the reciprocating motion of the piston rod
2. Structural performance:
The hydraulic control valve group is mainly composed of overflow valve, oil suction one-way valve, one-way valve, speed control valve (user requirements), hydraulic control one-way valve (hydraulic lock), etc. Different functional oil circuit combination valves can also be designed according to the working characteristics of the electro-hydraulic push rod to meet its working requirements.
. Generally, there are push out self-locking, pull back self-locking, and both push pull self-locking; There are adjustable and non adjustable operating speeds; The working angles of the electro-hydraulic push rod include horizontal pushing, upward pushing (including oblique upward), downward pushing (including oblique downward), and so on. The electro-hydraulic push rod has the following advantages:
(1) compact structure, easy installation, small space occupation, and simple maintenance
(2) It can start with load and has overload protection function(3) The circuit is equipped with a bidirectional hydraulic lock, which can stop at different positions within the specified travel range and lock itself, while keeping the output force unchanged(4) Push and pull force, speed (user requirements) are infinitely adjustable, with a wide range of driving forces(5) Due to power failure, the push rod will lock itself to avoid accidents(6) It adopts full hydraulic transmission, with sensitive action and smooth operation, which can effectively buffer external impact forces, and accurate stroke control (≥ 0.5mm)(7) The electromechanical hydraulic integrated fully enclosed structure circulates the working oil circuit in a pressure free closed steel cylinder, with a small volume and no oil leakage. In harsh working environments, it does not suck dust, water, rust inside, and has a long service life
