An electric over hydraulic cylinder, also known as an electric hydraulic actuator, is a type of actuator that combines the advantages of both electric and hydraulic systems. It utilizes an electric motor to drive a hydraulic pump, which in turn generates hydraulic pressure to actuate a hydraulic cylinder.
Key Features and Functions:
Electric control: The use of an electric motor allows for precise and flexible control over the actuation of the hydraulic cylinder. The electric motor can be controlled using various control methods, such as switches, buttons, or programmable logic controllers (PLCs), providing precise positioning and control.
Hydraulic power: The hydraulic pump driven by the electric motor generates hydraulic pressure, which is used to actuate the hydraulic cylinder. This hydraulic power enables the cylinder to produce high force, making it suitable for applications requiring heavy lifting or pushing.
Compact design: Electric over hydraulic cylinders are often designed to be compact and space-saving. The integration of the electric motor and hydraulic pump into a single unit reduces the overall footprint and simplifies installation.
Energy efficiency: The electric motor in an electric over hydraulic cylinder consumes power only when actuation is required, resulting in energy efficiency compared to continuously running hydraulic systems. This can lead to energy savings and reduced operating costs.
Design and Construction:
The design and construction of electric over hydraulic cylinders can vary depending on the specific application requirements. They typically consist of an electric motor, hydraulic pump, hydraulic cylinder, reservoir, control valves, and associated piping or tubing. The components are integrated into a compact unit that can be mounted directly onto the equipment or machinery.
Maintenance and Care:
Regular maintenance and care are necessary for the optimal performance of electric over hydraulic cylinders. This includes inspecting and maintaining the electric motor, hydraulic pump, seals, and other components. It is important to monitor hydraulic fluid levels, ensure proper lubrication, and address any leaks or issues promptly to prevent potential failures or performance degradation.
Applications:
Electric over hydraulic cylinders find applications in various industries, including material handling, construction, agriculture, automotive, and industrial automation. They are suitable for tasks such as lifting heavy loads, controlling gates or valves, operating hydraulic presses, or any application that requires precise and powerful hydraulic actuation with electric control.
In conclusion, electric over hydraulic cylinders combine the advantages of electric control and hydraulic power, providing precise positioning, powerful actuation, and energy efficiency. Their compact design and flexibility make them a versatile choice for applications that require the benefits of both electric and hydraulic systems.
