How to Correctly Replace the Hydraulic Oil of the Hydraulic Press

The operating speed of the hydraulic press is generally determined as follows: when the hydraulic press is working, the load of the hydraulic press is large and the working pressure is also high, so in order to ensure that the hydraulic pump is not overloaded, it is necessary to reduce the flow rate, that is, reduce the working speed of the hydraulic press; When the hydraulic press returns, its load is small and the working pressure is low, so the flow rate can be increased without exceeding the output power of the hydraulic pump, which increases the working speed of the hydraulic press. In general, the operating speed of the hydraulic press is only related to the flow. In other words, the larger the flow, the faster the speed, and the smaller the flow, the slower the speed!

The flow rate determines the running speed of the hydraulic press, and hydraulic oil is one of the indispensable media for the hydraulic components of construction machinery. When the hydraulic oil needs to be replaced due to excessive use of Drain the oil and fill up with new hydraulic oil. However, there are still many old hydraulic oil left in the hydraulic oil pipe and hydraulic control valve at this time. When the hydraulic press equipment is used, the mixed use of the old and new oil will speed up the deterioration of the new oil.​​

The correct oil change procedure of the hydraulic press should first drain the hydraulic oil in the hydraulic oil tank, clean the oil tank and add new hydraulic oil, then remove the circuit main pipe, start the engine and run in a sluggish operation, make the oil pump work, operate each mechanism separately, rely on the hydraulic oil Drain the old oil in the circuit one by one until new oil flows out from the oil return main pipe. Finally, connect the oil return main pipe to the oil tank and add new hydraulic oil to the oil tank to the specified position.
