Electro hydraulic push rod is a hydraulic driven robotic arm that integrates mechanical, electronic, and hydraulic technologies. It is suitable for situations that require reciprocating linear motion (or reciprocating rotation of a certain angle), as well as places that require lifting, lowering, or clamping of work objects. It can also achieve centralized or automatic control in remote hazardous areas.

working principle

The electro-hydraulic push rod drives the bidirectional hydraulic pump through the forward and reverse rotation of the electric motor, outputting pressure oil, which is sent to the oil cylinder through the hydraulic control valve to achieve the reciprocating motion of the piston rod. Its structure is compact, easy to install, occupies small space, and is easy to maintain.

Fault diagnosis and troubleshooting:

First, determine whether the fault is caused by the entire vehicle biting or individual biting, and then make further diagnosis.

(1) If the entire vehicle brakes are biting: 1. Check if the brake pedal has free travel. 2. Open the lid of the liquid storage chamber and use the "continuous tap" function

Method of braking pedal, observe the return oil condition. If the oil return is slow or does not return, check whether the brake fluid is too dirty or too viscous. If the brake fluid is pure, after stepping on the brake pedal once, release the brake pedal and loosen any one of the cylinder release bolts to spray out the brake fluid, and the biting phenomenon of the entire vehicle's brakes will be eliminated.

(2) If a few wheels bite: 1. First support the brake biting wheel, loosen the cylinder exhaust bolt, and if the brake fluid is urgent

After rapid spraying, the brake shoe will move back and check if the brake oil pipe is blocked. 2. After draining the fluid, if the brake shoes still cannot move back, check if the brake clearance is too small. If all the above checks are normal, then disassemble and inspect the cylinder piston, cup, and other factors that cause poor brake shoe return.

The hydraulic braking device converts pedal force into hydraulic energy to transmit braking force. Its transmission mechanism is simple, but the braking torque generated by the brake is linearly related to the pedal force. If the adhesion between the tire and the road surface is sufficient, the braking force received by the car is linearly related to the pedal force. This performance is called brake pedal feel (commonly known as foot feel), which allows the driver to directly feel whether the various working conditions of the car's braking system are normal, in order to quickly diagnose. Common faults in hydraulic braking systems include: ineffective braking such as brake biting.

Structural composition: The electro-hydraulic push rod is a new type of flexible transmission mechanism that integrates mechanical, electrical, and hydraulic components. It consists of an actuator (oil cylinder), a control mechanism (hydraulic control valve group), and a power source (oil pump motor, etc.). The hydraulic control valve group is mainly composed of overflow valve, oil suction check valve, speed regulating valve (user requirement), hydraulic control check valve (hydraulic lock), etc.

Working principle: The electric motor drives the bidirectional hydraulic pump to output pressure oil in both directions through forward and reverse rotation, and sends it to the oil cylinder through the hydraulic control valve to achieve the reciprocating motion of the piston rod, thereby completing the action of pushing and pulling straight lines or reciprocating rotation at a certain angle.

Product Features:

Overload protection: With reliable overload automatic protection performance, even when overloaded or running to the end of the stroke, the motor will not burn or damage other parts.

Load start: It can start with load, which is difficult for electric push rods and electric actuators to achieve.

Thrust adjustment: Within the rated range of thrust and tension, the thrust and tension can be infinitely adjusted, and the driving force range is wide.

Energy saving and efficient: Under the same thrust and speed, the energy consumption is half of that of electric push rods and electric actuators.

Smooth operation: Adopting full hydraulic transmission, the action is sensitive, the operation is smooth, and it can effectively alleviate external impact forces, with accurate stroke control.

When choosing an EMG electro-hydraulic thruster, multiple factors need to be considered comprehensively to ensure that a product suitable for practical application needs is selected. Here are some key purchasing methods:

1. Determine the model and special requirements:

Firstly, it is necessary to clarify the required push rod model. EMG's electro-hydraulic thrusters have different models such as ED series and EB series, and the performance and characteristics of each model vary. At the same time, it is necessary to consider whether there are special requirements, such as special dimensions, working environment conditions, etc. Some dimensions can be customized according to customer usage scenarios and requirements, but it should be noted that the production cycle of customized products needs to be determined through mutual consultation.

2. Consider the usage environment:

The usage environment is an important consideration factor. If the environment is harsh, such as high temperature, high humidity, strong corrosive gases or dust, the sealing components of the push rod and its accessories need to meet the corresponding protection level and requirements for high temperature and corrosion resistance, otherwise it will affect the performance and service life of the thruster.

3. Determine the output format:

Select the corresponding output form based on the motion trajectory of the controlled object by the thruster. If used for gate valves, globe valves, etc., a multi turn output shaft may be required; For butterfly valves, ball valves, etc., some rotary output shafts are more suitable; For situations that require linear thrust action, such as regulating valves, a linear output shaft should be selected.
