What is the difference between hydraulic press and ordinary hydraulic press


​​




1. Driving method: The hydraulic press is driven by a motor and is used for the pressure assembly of high-precision ball screws. The pressure is converted directly by the torque output of the motor. The ordinary hydraulic press is driven by the motor oil pump, changes the direction through the reversing valve, and then performs pressure operation through the hydraulic cylinder. The pressure passes through the oil pipe and the valve body, and there is a certain loss.



2. Energy saving and environmental protection: The hydraulic press adopts electric motor. When the machine is in standby mode, the motor does not spin. In addition, the speed and power were changed during the installation of the press. In an ordinary hydraulic press, the motor always rotates when it is in standby, requiring a certain amount of power. It also rotates at a constant speed during work and will consume more power. The noise is also higher compared to the motor.







3. Precise control: The hydraulic press can set multi-stroke speed, precise displacement stop, precise position stop, and precise pressure stop within a certain range. However, ordinary hydraulic machines are affected by the sealing of pipelines, valve bodies and cylinders, and it is impossible to carry out high-precision control, and many are achieved through mechanical limits. If the control accuracy of the electronic press is close, the equipment cost will be much higher than that of the electronic press, and the control will be more complicated.

4. Function: The hydraulic press has the following functions: online quality determination of the press: the whole process curve of the pressing force and displacement can be displayed on the LCD touch screen; the whole process control can automatically determine whether the product is eligible for operation at any stage, and reject Defective products 100% of the time, enabling online quality management. The pressing force, pressing depth, pressing speed, holding time, etc. can be input on the operation panel, with friendly interface and simple operation. It can customize, store and recall 100 sets of ballast programs themselves: seven types of ballast modes to meet your different process requirements. The machine itself has precise pressure and displacement control, so there is no need to add additional hard limits on the tool. When processing products of different specifications, different pressing processes are required. By connecting the computer through the external port, the ballast data can be stored in the computer to ensure the traceability of the product processing data, which is beneficial to the production quality control management.
