The hydraulic press has the characteristics of large installed power, high working pressure, large flow, and high frequency. In recent years, more and more attention has been paid to the research on energy-saving technology of hydraulic presses, and green energy-saving is also one of the development trends of a hydraulic press.
The methods of saving energy consumption of the hydraulic press are as follows:
1.The hydraulic press should choose the volume speed regulation method as much as possible
1).Using the flow combination of multiple pumps: to achieve the purpose of speed regulation, this method is an ideal way to save energy.
2).Speed regulation by variable pump: closed-loop pressure control can be carried out by using the hydraulic oil source driven by the motor and the pressure sensor of the main cylinder, which can achieve high-pressure control accuracy and pressure holding accuracy, and at the same time, the energy consumption is very low.
2.Reasonable selection of hydraulic valve for hydraulic press
1).Conventional slide valve: The leakage and internal pressure loss of this type of valve are relatively large, and it is suitable for applications with low pressure and small flow.
2).Cartridge valve type: The valve port of this type of valve adopts a conical surface sealing structure, which generally has no leakage and has obvious advantages over conventional slide valves. Therefore, when designing a hydraulic press system, try to use a cartridge valve.
3.Optimize hydraulic press system design
1) Reasonable selection of hydraulic valve specifications: Calculate the flow required for each action of the hydraulic press.
2) Correctly design the oil block: try to increase the inner diameter of the oil block and reduce the flow rate.
3) Optimize the pipeline design: shorten the pipeline as much as possible, use flange connection, and use fewer threaded pipe joints.
4) Reasonably choose the viscosity of the hydraulic oil: the commonly used hydraulic oil is N30-N68, and the maximum value is taken in the high-temperature season or region。
4. Reasonable use and maintenance of the hydraulic system
Pay attention to the cleanliness of the hydraulic oil, and replace the filter element regularly; when disassembling and washing parts, avoid dirt from entering the system.
