D electro-hydraulic push rod
D electro-hydraulic push rod is an electro-hydraulic push rod, which is suitable for reciprocating push and pull linear (or reciprocating rotation at a certain angle) motion and can be used for
raising, lowering or clamping work objects It can also 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 as an indispensable universal power source.
Principle and function of D parallel electro-hydraulic push rod
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 to cause the hydraulic oil to output pressure oil through the bidirectional gear pump. The oil circuit manifold is sent to the working cylinder to realize the reciprocating motion of the piston rod.
. 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. At this time, the oil pressure in the oil circuit increases to the set pressure and overflows. The flow valve overflows quickly and accurately to realize 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 continuously adjusted 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 level and insulation level.
,
If the stroke manufacturing range or speed manufacturing range is beyond the listed range, 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 powers listed in the table refer to 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 D electro-hydraulic push rod
Compact structure, convenient installation, small space occupation and simple maintenance
There is a two-way pressure-maintaining self-locking device in the circuit, which can stop at any position within the specified stroke range. And it is self-locking and keeps the output force unchanged
. When the mechanism has an accident and the power is cut off, the push rod can be automatically locked in this position to avoid accidents
. All hydraulic devices are concentrated in the body and there is no external pipeline. The cylinder seal They all use imported famous brand seals, which have good sealing effect, no oil leakage and pollution, and long service life. The electrical control is simple. By adding various limit switches, it is easy to realize remote and dangerous area operation control and computer automatic control.
Precautions when installing and using D parallel electro-hydraulic actuator
. The electro-hydraulic actuator must be installed with enough space and the ambient temperature is between - degrees (high temperature environments must be specially ordered).
. Users can configure the limit switch according to control needs.
. Before installing the electro-hydraulic push rod, place it flat on the ground and inject hydraulic oil (brand. Accuracy level -). The oil level at the lower edge of the observation port should be within the range of the separation box.
. D, D, and D should loosen the exhaust screw ring of the exhaust hole before use.
. Please try booting when installing.
. The integral push rod can be operated when connected to the power supply
. The split push rod is connected to the power supply to allow the cylinder to reciprocate several times without load to discharge the air in the cylinder and oil pipe
Bring the load.
