Electro-hydraulic push rod, that is, electro-hydraulic push rod, is suitable for reciprocating push and pull linear (or reciprocating rotation at a certain angle) motion, and can be used for rising and falling Or places where work is clamped, 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 and transportation and other departments. It is an indispensable universal power source. 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, and is sent to the work through the oil manifold block. The oil cylinder realizes the reciprocating motion of the piston rod. Advantages:

Has 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 circuit When the oil pressure increases to the set pressure, the relief 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. Stepless adjustment: Stepless adjustment can be made within the rated speed output force and stroke range according to user requirements.

Model Description The electro-hydraulic push rod is mainly composed of six basic elements including the type of the push rod, the protection level of the motor, the rated output force, the stroke, the rated speed and the angle of use. It can also be equipped with three supporting elements according to the special requirements of the customer. Adjustment functions, namely: speed adjustment, push-pull force adjustment, stroke adjustment (stroke switch positioning). Except for the above three adjustment functions, which must be clearly stated when ordering, please refer to the model preparation method and fill in the six major elements carefully.

Note: The voltage levels of the motors listed in the above table are , the protection level is , and the insulation level is Class B. 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 powers listed in the table indicate the power of this type of push rod when the rated output force and rated speed are at the maximum value. Motor power is directly proportional to the push rod thrust speed.

Precautions during installation and use
The electro-hydraulic actuator should be installed with enough space and the ambient temperature should be between 10 and 10 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. Inject hydraulic oil (brand accuracy 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 the computer during installation.
Integral push rod, it can be operated when connected to the power supply
b 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. Loading

Maintenance of the electro-hydraulic push rod
In order to ensure the service life of the high-pressure oil pipe, the oil pipe must be fixed with rubber.
Hydraulic oil must be filtered or replaced regularly, once a year or at a customized period based on actual work.
If the motor is left idle for a long time, the insulation of the motor must be checked before being put into use.
Simple troubleshooting
If it cannot operate when it is first installed, check if the motor is not running or there is insufficient oil.
b If it cannot operate after being used for a period of time, remove the hydraulic control plug, clean the spool of the hydraulic control valve, and replace the hydraulic oil.
After being used for a long time, the push rod can be pushed and pulled without load, but cannot stand with load. Replace the seal for the upper hole of the piston in the cylinder. If the sealing surface leaks, replace the seal. If oil drips from the extension of the oil plug rod, replace the shaft seal.
