Zhengzhou hydraulic push rod Shandong electro-hydraulic push rod
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 in places where work objects are raised, lowered or clamped , 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, and 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 working cylinder through the oil circuit integrated block to realize the piston rod reciprocating motion. Advantages
It 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 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. The oil circuit integrated block of the locking function electro-hydraulic push rod is designed with a pressure self-locking mechanism. When the motor stops rotating, the piston rod immediately stays in a certain position, and the pressure oil is in a pressure-maintaining state. Step adjustment can be carried out steplessly within the rated speed, output force and stroke range according to user requirements.
Style description The electro-hydraulic push rod is mainly composed of six basic elements such as the type of 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. There are three types of adjustment functions, namely speed adjustment, push adjustment, pull adjustment, and stroke adjustment (positioning of the stroke switch). 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 level of the motors listed in the above table is , the protection level is , and the insulation level is level . , 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 push rod thrust and speed.
Precautions during installation and use
There should be enough space for the installation of the liquid push rod, and the ambient temperature should be between 10 and 10 degrees Celsius (high temperature environments must be specially ordered).
Users can configure the travel switch according to control needs.
Before installing the hydraulic push rod, place it flat on the ground. Inject hydraulic oil (brand and 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.
. Loosen the exhaust screw ring of the exhaust hole before use.
Please try turning on the computer during installation.
Body push rod, connected to the power supply, it can operate
Body push rod, connected to the power supply, allows the cylinder to reciprocate several times without load to discharge the air in the cylinder and oil pipe, and then load the
Maintenance of electro-hydraulic push rod
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 it is not used for a period of time, the insulation of the motor must be checked before it is put into use.
Easy troubleshooting
If it cannot operate during installation, check if the motor is not running or there is insufficient oil.
If it fails to 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.
