What are the maintenance methods for hydraulic presses?

As a maintenance personnel from an oil press manufacturer, first check the specific working conditions of the hydraulic transmission system of the oil press, and check if there are any problems with the working pressure, speed, hydraulic oil, leakage, vibration, etc. of the oil press system software.
Listen to the sound of the hydraulic transmission system of the hydraulic press, such as the impact sound; Abnormal sound from the centrifugal water pump of the hydraulic press; Distinguish whether the hydraulic transmission system of the hydraulic press is working properly.
Based on the temperature rise, vibration, crawling, and connection tightness of the touch controlled four column hydraulic press, it is possible to distinguish whether the running status of fitness components is normal.
How to diagnose and avoid common faults of high oil temperature on a four column hydraulic press?
The four column hydraulic press has a large load during operation, but its operating speed is relatively slow. The load is smaller during fast release and fast retreat, but the operating speed is faster than during operation. To improve the working efficiency of the hydraulic press, oil provided by secondary pumps or variable frequency pumps can be selected. The hydraulic press selects the oil provided by the variable displacement plunger pump, taking into account comprehensive considerations.
In addition, because the load working pressure under the standard during the operation of the hydraulic press will gradually increase, in order to ensure that the hydraulic press operates under the safety production working standard, a constant output power variable piston pump is selected for the variable speed control circuit. With the increase of the working pressure of the load, the exhaust volume of the pump automatically decreases, and the multiplication of the working pressure of the hydraulic press and the total flow rate is maintained as a constant parameter, that is, the output power will not change.
Therefore, during the operation of the hydraulic press, the most important thing to pay attention to is not to load, which can prevent safety production accidents caused by incorrect operation.
