Working hydraulic oil deterioration by the dirt (eg dust, sand, soil, etc.) which are sources are from:
(A) an external hydraulic system dirty. Dirty things when refueling or checking the oil being brought into the system, or by a damaged seal or seal ring into the system;
(2) Internal cleaning is not thorough. Fuel tank and components inside are still left traces of dirt residue;
(3) Fuel containers or utensils unclean;
(4) The pipe when bending left iron rust;
(5) oil improperly stored. Before oil joining the system unclean or has suffered deterioration
(6) has gradually deteriorated oil will corrode parts. Metal may be corroded free molecules suspended in oil.
Dirt can cause hydraulic cutting machine parts to wear and corrosion, especially for finishing parts, they will scratch the inner wall of hoses, seal ring and packing, but these things can cause more damage then dirt into the system, so to a vicious cycle of damage.So Gerson machinery advise the customers that make sure the hydraulic oil clean before to add the hyedraulic cutting machine.
