Electro-hydraulic push rod
Integral straight electro-hydraulic push rod
Electro-hydraulic push rod
Electro-hydraulic push rod, that is, electro-hydraulic push rod, is suitable for reciprocating push and pull in a straight line (or reciprocating rotation at a certain angle) Movement can be used in places where work objects are raised, lowered or clamped, and 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
br/>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. When the set pressure is reached, the overflow valve will overflow quickly and accurately to realize 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.
