The Ed series electro-hydraulic thrusters are sophisticated devices designed to offer precise control and drive functionality in various industrial applications. These thrusters integrate a motor, centrifugal pump, and cylinder into a compact structure, making them ideal for driving and controlling block brakes, disc brakes, industrial valves, gates, directional swings, rotations, and clamping devices. Below is a detailed analysis of their advantages, application range, working principles, and usage methods.
Advantages
- Robust Design and High Performance:
- The Ed series thrusters are manufactured using advanced technology sourced from the former West Germany EMG company, adhering to DIN15430 and JB/T 10603-2006 standards. This ensures high reliability and optimal performance.
- The thrusters feature an aluminum alloy shell with a fully sealed single push rod structure, contributing to their aesthetic appeal, lightweight nature, and comprehensive functionality.
- Variety and Customization:
- The series includes a wide range of models, from the Ed23 with a rated thrust of 220 N to the Ed630/l2 capable of delivering 6300 N, catering to diverse industrial needs.
- Customization options are available for different voltages and frequencies, accommodating various operational requirements.
- Durability and Protection:
- The motors are non-oil-immersed with F-class insulation, ensuring excellent heat resistance and longevity.
- The electrical protection level is IP65, making the thrusters suitable for use in environments with corrosive media and high humidity.
- Enhanced Control:
- The thrusters can be equipped with additional devices such as limit switches and delay valves to adjust the ascent and descent times, providing precise control over operations.
Application Range
The Ed series thrusters are versatile and can be applied in numerous industrial sectors, including:
- Brake Systems: Used in block and disc brake systems for reliable actuation.
- Valve and Gate Control: Effective in controlling industrial valves and gates, ensuring smooth operation.
- Directional Movement: Suitable for devices requiring directional swings or rotations up to 90 degrees.
- Clamping Devices: Provide controlled force for secure clamping applications.
Working Principles
The Ed series electro-hydraulic thrusters operate by using a motor to drive a centrifugal pump, which in turn generates hydraulic pressure to actuate the cylinder. This mechanism allows precise control over the push rod movement, facilitating various mechanical processes such as braking, clamping, and directional control.
Usage Methods
- Installation:
- Thrusters can be installed vertically, with the piston rod connection block facing upwards, or horizontally as needed. Models such as Ed50-Ed301 allow for a 90-degree rotation of the mounting base.
- It is crucial to ensure that the piston rod does not bear radial forces to prevent impact on performance and lifespan.
- Operation:
- The thrusters can operate continuously (S1) or intermittently (S3-60% duty cycle). Specific models like the Ed23/5 and Ed30/5 offer short strokes, while others like Ed301/12 provide long stroke capabilities.
- Environmental Considerations:
- Suitable for ambient temperatures ranging from -20°C to 50°C. In conditions below -20°C, heaters can be added to maintain operational efficiency.
- For environments with corrosive air, special anti-corrosion treatments are available.
Special Considerations
- Spring Mechanisms:
- Short stroke thrusters can be equipped with various springs (C-spring for braking force, W-spring for reset, D-spring for buffering) to enhance operational control.
- Heating Options:
- Heaters can be installed for operation in low-temperature settings, with specifications available in AC110V or AC220V.
Overall, the Ed series electro-hydraulic thrusters are engineered for excellence in performance, adaptability, and durability, making them a reliable choice for a wide array of industrial applications.
The model naming convention for the Ed series thrusters is structured as follows:
- Ed: Indicates the series code for electro-hydraulic thrusters.
- First set of digits: Represents the rated thrust code, which indicates the maximum thrust the thruster can deliver.
- Second set of digits: Denotes the rated stroke code, specifying the maximum stroke length of the thruster.
- Digits after the slash (“/”): Indicate the auxiliary device code, which specifies any additional features or devices integrated with the thruster.
Example: Ed50/6
- Ed: This is the series code, indicating that the product is part of the Ed series of electro-hydraulic thrusters.
- 50: This is the rated thrust code, which means the thruster is capable of providing 500 N of thrust.
- 6: After the slash, this number represents the rated stroke code, indicating the thruster has a stroke length of 60 mm.
- Auxiliary device code: This part of the model can specify additional features or devices integrated into the thruster, although in this example, there is no specific code following the stroke code.
