Electro-hydraulic push rod, that is, electro-hydraulic push rod, is suitable for reciprocating push-pull linear (or reciprocating rotation at a certain angle) motion. It can be used in places where work objects are raised, lowered or clamped, and also It can be used in remote and high-altitude dangerous areas, and can be networked with computers for centralized (program) control. Now it is widely used in metallurgy, mining, coal, electric power, machinery, food, cement, chemical industry, water conservancy, transportation and other departments, and is an indispensable universal power source.
Principle and function of parallel electro-hydraulic push rod
Working principle The electro-hydraulic push rod uses an electric motor as the power source, and the electric motor rotates in the forward (reverse) direction, so that the hydraulic oil outputs pressure oil through the two-way gear pump. It is sent to the working cylinder through the oil circuit manifold 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 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.
, The speed can be adjusted steplessly within the rated speed range according to user requirements.
. The push and pull force can be adjusted steplessly within the rated output force range according to user requirements.
. The stroke can be adjusted steplessly within the rated stroke range according to user requirements.

Note, the voltage level of the motors listed in the above table is, protection The grade is , and the insulation grade is grade .
,
If it exceeds the stroke manufacturing range or speed manufacturing range listed in the table, please indicate it separately, otherwise it will be manufactured according to the technical parameters in the table.
The speed range in the table is for horizontal use. The speed for upward or downward use is half of that for horizontal use.
The typical numbers and power listed in the table are the power of this type of push rod when the rated output force and rated speed are at the maximum value. The motor power is directly proportional to the thrust and speed of the push rod.
Main features of electro-hydraulic push rod
Compact structure, easy installation, small space occupation, simple maintenance
There is a two-way pressure-maintaining self-locking device in the circuit, which can operate within the specified stroke range It stops at any position and locks itself, and keeps the output force unchanged
. When the mechanism has an accident and loses power, the push rod can be automatically locked in this position to avoid accidents
. All hydraulic devices are concentrated in the body. , no external pipes, the cylinder seals are all imported famous brand seals, with good sealing effect, no oil leakage pollution, and long life
, simple electrical control, by adding various limit switches, it is easy to achieve remote control and operational control in hazardous areas, as well as computer automatic control.
Precautions when installing and using parallel electro-hydraulic actuators
. The electro-hydraulic actuator must be installed with enough space and within the ambient temperature range (special orders must be made for high-temperature environments).
. Users can configure the limit switch according to control needs.
. Before installing the electro-hydraulic push rod, place it flat on the ground. Inject hydraulic oil (brand and precision grade) and the oil level should be at the lower edge of the observation port. The oil level of the split push rod should be within the box.
. The exhaust screw ring of the exhaust hole should be loosened before use.
. Please try booting when installing.
. Integral push rod, it can be operated when connected to the power supply
. Split push rod, connected to the power supply, the cylinder can reciprocate several times without load to discharge the air in the cylinder and oil pipe
