The right steps to change the hydraulic oil in the hydraulic arm cylinder
There are many hydraulic components on construction machinery, which requires sufficient hydraulic oil. When the hydraulic oil needs to be replaced due to deterioration for a long time, some people mistakenly believe that it is only necessary to light up the oil in the hydraulic arm cylinder and fill it with new hydraulic oil. However, at this time, there are still many old hydraulic oils left in the hydraulic oil pipes and hydraulic control valves. When the equipment is used, mixing old and new oils will speed up the deterioration of new oils.
The correct oil change procedure should first release the hydraulic oil in the hydraulic arm cylinder, clean the hydraulic arm cylinder and add new hydraulic oil, then remove the circuit manifold, start the engine at low speed, make the oil pump work, and operate the mechanisms separately. The hydraulic oil drains the old oil in the circuit one by one until new oil flows out of the oil return main. Finally, connect the oil return main to the fuel tank and fill the tank with new hydraulic oil to the specified position.
Of course, this oil change also has its drawbacks. Let ’s talk about a loader with a pilot. In this oil change, the pilot oil pressure will be 35 kg when idling first. The oil return pipe is not necessarily enough to prepare 3 large barrels of hydraulic oil. In addition, there is not only one oil return pipe, which needs to be removed one by one, so it is very troublesome to do one by one.
There are usually two types of exhaust devices: one is to open the exhaust hole at the highest position of the hydraulic boom cylinder and use a long pipe to exhaust the exhaust valve at a distance; the other is at the highest position of the cylinder head Install the exhaust valve directly. For the double-acting hydraulic pump station system, the hydraulic boom cylinder should be provided with 2 exhaust valves.
The role of oil in the hydraulic arm cylinder
The quality of the hydraulic oil in the cylinder of the hydraulic arm is very important. A better hydraulic oil contains a preservative, which can increase the shelf life of the oil, but if it is long, it needs to be replaced again, otherwise the preservative in the hydraulic oil will fail It will damage the effectiveness of the hydraulic machine. When replacing the hydraulic oil, the filter must be carefully cleaned, because the filter only filters out the dirt and dirt in the oil, there is no way to filter other substances contained in the oil.
The density of hydraulic oil will change with the change of temperature, the temperature will increase, the density will decrease, but the change is small, generally considered as a constant, the viscosity changes with the change of temperature. Before use, be sure to keep the hydraulic oil clean. Keep the oil in a sealed place. It is not possible to expose it to the sun or get wet. When adding oil to the tank, you must choose a suitable filter to filter it. . In the process of adding, it is necessary to ensure that all containers are clean and clean. If the dirt enters the oil, the hydraulic oil needs to be replaced again. Remember to keep all appliances clean.
