Electro-hydraulic push rod and electric push rod, electric actuator, hydraulic cylinder, cylinder compared with the following advantages:
1, with reliable overload automatic protection performance, even if overload or run to the end of the stroke, the motor still runs normally, but will not burn or damage other parts. Electric push rod, electric actuator can not be comparable.
2. The electro-hydraulic push rod can be started with load, while the electric push rod and electric actuator are very difficult.
3, the same electric hydraulic push rod in its rated push and pull range, the push and pull can be stepless adjustment, so the drive range is wide, and the electric push rod and cylinder can not do.
4. In the case of the same thrust and speed, the electric hydraulic push rod consumes half of the electric push rod and the electric actuator.
5, the electro-hydraulic push rod adopts full hydraulic transmission, sensitive action, smooth operation, can effectively alleviate the external impact force, stroke control is accurate, cylinder, electric push rod and electric actuator can not do.
6. Electro-hydraulic push rod adopts electric and hydraulic integrated closed structure, working oil circuit circulation and no pressure closed steel cylinder, small volume, no oil leakage, easy installation and maintenance. In harsh environment, no vacuum, no water, no internal corrosion, service life than cylinder, electric push rod and electric actuator for a long time.
7. The investment is small, the cylinder needs to build expensive air compressor station, and the pressure pipe Louie leaks, the pressure is unstable, and the noise is high; The hydraulic cylinder needs to build a hydraulic station, and the electro-hydraulic push rod only needs to be connected with the power supply.
8, easy maintenance. In special cases, the electro-hydraulic push rod only needs to be replaced, while the hydraulic cylinder needs to be slowly identified first, and then carefully repaired, which will affect the normal operation of all work.
The electro-hydraulic push rod, that is, the electro-hydraulic push rod, is suitable for reciprocating push and pull straight line (or reciprocating rotation of a certain Angle) motion, can be used to rise, fall or clamp the work place, can also be used for long distance and high altitude dangerous areas, and can be networked with the computer for centralized (program) control. Has been widely used in metallurgy, mining, coal, electric power, machinery, food, cement, chemical industry, water conservancy, transportation and other departments, is an indispensable general power source. Working principle:
Electro-hydraulic push rod with motor as power source, through the motor positive (reverse) rotation, so that the hydraulic oil through the two-way gear pump output pressure oil, through the oil circuit integrated block, sent to the working cylinder, to achieve the reciprocating movement of the piston rod. Advantages:
1. With overload automatic protection function: when the electro-hydraulic push rod works, such as the piston rod by external force exceeds the rated output force or the piston has reached the end, the motor is still rotating, then the oil pressure in the oil circuit increases to the set pressure, the relief valve quickly and accurately overflow, to achieve automatic overload protection. The motor is running, but it will never burn out.

2. Self-locking function: the pressure self-locking mechanism is designed in the oil circuit integrated block of the electro-hydraulic push rod. The motor stops rotating, the piston rod immediately stays in a certain position, and the pressure oil is in a state of pressure preservation.

3. Stepless adjustment: According to user requirements, stepless adjustment can be carried out in the rated speed, output force and stroke range.
