The bending machine with a lot of hydraulic parts, must be sufficient gear oil. When the gear oil must be removed because of too much application time, some people incorrectly feel that only the oil in the hydraulic press E-mail box must be illuminated and filled with new gear oil. However, hydraulic tubing and hydraulic control valves still have a lot of old gear oil. When the machine is used, the mixing of old and new oil will accelerate the deterioration of the new oil.
The proper oil change process of the bending machine should be the first to release the gear oil in the hydraulic press E-mail box, clean the car fuel tank and add new gear oil, then remove the head of the control loop, start the diesel engine and make the accelerator pedal run, so that the gasoline pump work, independent practical operation organization, with the old oil in the gear oil control loop 1 by 1 to discharge out. Until the pump head has new oil discharge. The pump head is connected to the fuel tank, and new gear oil is added to the fuel tank to specific locations.
Perhaps, this kind of method to change the oil into a bending machine is also its defect, I heard that there is a leading small forklift, so that the oil change, wait for the speed first, the main oil working pressure is 35KG, only the diesel engine, the main oil (that is to say, the new oil) if the return pipeline, it is not necessary to prepare 3 barrels of gear oil in advance. Another, not only a return water pipe must be disassembled one by one, so it is very inconvenient to do one by one.
As the saying goes: "The knife is not idle carpenter", friends do not bother! Imagine that although the oil transition is slow, it depends on the actual model size and condition, but this allows it to happen within a morning to a day. How much will this machine earn today? If 1 component is destroyed due to environmental pollution of the bending machine, in addition to maintenance time and cost, how much must the parts cost? This is definitely not sensational!
