There are some key differences between electric hydraulic presses and traditional presses, which are mainly reflected in the driving mode, working principle, scope of application and other aspects.
Drive mode
Electric hydraulic press: The hydraulic pump is driven by an electric motor, and the pressure is generated through the hydraulic system. The hydraulic oil flows in the system to achieve the pressing function.
Traditional press: The mechanical transmission device, such as crankshaft, gear, screw, etc., is directly driven by the electric motor to generate pressure for work. The press may also have pneumatic, hydraulic and other drive modes according to different designs.
Working principle
Electric hydraulic press: The electric motor drives the hydraulic pump, and the pressing force is generated by the flow of hydraulic oil in the pipeline system. The hydraulic system can provide strong and stable pressure, which is suitable for heavy load and high-precision operations.
Traditional press: The mechanical device is driven by the electric motor to act directly on the workbench, and the pressure is usually achieved through mechanical transmission (such as crankshaft, screw, etc.).
Scope of application
Electric hydraulic press: suitable for working environments that require higher pressure or heavy loads, such as metal forming, mold pressing, stamping, etc. The hydraulic system can provide greater pressure and can perform larger load operations in a shorter time. Industrial electric hydraulic presses are suitable for complex process requirements.
Traditional presses: suitable for more conventional pressing, stamping, forming and other operations, especially in some light or medium load applications, such as stamping and press-fitting of small parts.
Pressure regulation and precision
Electric hydraulic press: The hydraulic system can achieve more flexible and precise pressure control, suitable for tasks that need to work under different pressure conditions.
Traditional press: The pressure of the press is adjusted by mechanical transmission, and the pressure regulation method is relatively simple, which is suitable for occasions where the pressure demand is relatively fixed or low.
Operation and maintenance
Electric hydraulic press: It is necessary to regularly check and replace the hydraulic oil and perform maintenance on the hydraulic system. Especially during long-term operation, the hydraulic system of the hydraulic power press may leak or lose.
Traditional press: The mechanical structure of the press is simpler, and maintenance work mainly focuses on the maintenance and lubrication of mechanical parts.
Energy efficiency and environment
Electric hydraulic press: Although the hydraulic system can provide greater pressure, it may not be as energy efficient as a purely mechanically driven press because there may be some energy loss in the hydraulic pump and oil flow.
Traditional press: Directly drive the mechanical transmission through the electric motor, with higher energy efficiency, no use of hydraulic oil, and a cleaner working environment.
Electric hydraulic presses mainly rely on hydraulic systems to provide high force and flexible pressure control, suitable for heavy loads and complex processing tasks.
Traditional presses rely on electric motors to directly drive mechanical devices, suitable for lighter loads and medium pressure work.
You can choose the appropriate equipment based on factors such as processing technology, pressure requirements and equipment maintenance requirements.
