Correction of Hydraulic Press Technical Parameters
Hydraulic press is widely used in industrial production due to its simple structure, convenient maintenance, stable performance and strong lifting force. However, due to changes in process parameters and long-term use, the original parameters of the hydraulic press will be affected, resulting in lack of stability and power, affecting the quality of products. In order to maintain its high stability and productivity, it is necessary to correct the technical parameters of the hydraulic press.
First of all, the temperature should be adjusted. The temperature of the hydraulic oil increases during the operation, which affects its viscosity, stability, oxidation rate and other performance indicators. Therefore, it is necessary to make sure that the temperature of the hydraulic oil is in the optimal range. The normal temperature of the hydraulic oil is 35~70℃, so the temperature of the oil should be adjusted to meet the requirements.
Secondly, the hydraulic oil should be replaced regularly. After long-term use, due to the increase of the water content and the oxidation of the oil, the lubrication performance of the oil will be reduced and the useful components of the oil will be lost, which will affect the stability of the system operation. Therefore, the hydraulic oil needs to be replaced regularly to make sure it is within the optimal range.
Thirdly, the pipes and seals need to be checked regularly. If the pipes and seals are not properly sealed, the oil will leak out and the system pressure will become unstable. Therefore, it is necessary to check the pipes and seals regularly to make sure there are no leaks.
Fourthly, the technical parameters of the motor need to be adjusted. The motor is the power source of the hydraulic press, and its performance will be affected by the changes in voltage and current. Therefore, in order to ensure the stability of the system operation, it is necessary to adjust the parameters of the motor in time according to the changes in voltage and current.
Fifthly, the system pressure needs to be adjusted. The system pressure should be monitored regularly to make sure it is within the normal operating range. The normal operating pressure of hydraulic system is 0.2-0.4 MPa, and if it is lower or higher than this value, it needs to be adjusted.
Finally, the safety protection device needs to be inspected and tested regularly. The safety protection device plays an important role in ensuring the safe operation of the hydraulic press, so it needs to be inspected regularly to make sure it can work properly.
In summary, in order to ensure the high stability and productivity of the hydraulic press, it is necessary to correct the technical parameters of the hydraulic press in time. Temperature, oil, pipes and seals, motor parameters, system pressure and safety protection device need to be paid attention to. Only by doing all these can the safety and efficiency of the hydraulic press be ensured.
