When it comes to storing your hydraulic cylinder, it is not just a case of putting it in the storage room and waiting until you may need it. Looking after this component before you use it can extend its lifespan and ensure that when you rotate or change out a cylinder you are doing so with one that is still in good condition.
Cylinders need to be kept indoors in a dry, clean area, and should be stored fully retracted. All exposed metal should be covered and protected. Grease can be put on the internal surfaces of the cylinder while a special tape infused with oil is wrapped around the exposed chrome. Before applying the tape, retract the rod otherwise the tape can damage the rod seal. Plug all service points with steel.
An additional option is to consider filling the cylinder with clean hydraulic oil. If the oil is not applied to the cylinder, it will be exposed to air. If the air has excessive moisture, it can cause the rod to rust and become pitted which will have serious consequences when the rod is in operation. This will decrease the effectiveness of the cylinder and its lifespan. If the cylinder is filled with clean oil after it is cleaned, damage to the cylinder can be avoided.
There are many factors that need to be considered when filling the cylinder with oil. If the cylinder is put into storage in winter, and then taken out to be used during summer the ambient temperature of the oil in the cylinder is going to rise causing issues when blanks on the cylinder’s service ports are opened.
When filling a cylinder with oil, the following should be contemplated:
Although this procedure is very technical, not taking the time to do it can damage the cylinder should it be in storage for a long period of time.
