Laser cutting machine repair improper oil. What should I do

General maintenance staff, when they found the O ring on the cutter deformation or damage to the need to change, tend to just find a similar size shape seal installation, rarely consider the size of the pressure, under normal circumstances, the general cutting machine lubrication pressure < 3 mpa, thus producing a kind of wrong idea, O ring as long as the same size, it can be used to replace. Promised some leakage inside the equipment, but do not allow penetration electrical box and transmission belt, bending machine can be brought back to lubrication in the box. For example: O ring caused by improper oil leakage often occurs in maintenance. Whether dynamic joint surface is still a static joint surface, every 2 ~ 3 min drip a drop of oil, as the drops of oil; All lubrication part every 5 s drip a drop of the above are the flow of oil. In general, the static combining face, every half an hour to drop a drop of oil and dynamic combination of facial every 6 min drip a drop of oil are leaking. Laser cutting machine oil is divided into three states that oil leakage and dripping and flow. 1. Choose improper assembly related parts to choose or assembly differences caused the situation of the oil spill are common. The general requirements of equipment for leakage is: external static binding surface shall not have leakage phenomenon; Dynamic binding surface to have a little leakage, but not allowed to flow to the ground. That in the case of low pressure is ok, but when encounter more than 5 mpa pressure high, will be on the subject. Often find some equipment still leak after replace the sealing ring, still further compression screw oil leak, don't realize is improper replacement of seal oil, between the box body and box cover joint surface with paint, burr, impurities or bruised, make joint surface joint is lax, bending machine and gasket or remove when loading has been forgetful will damage the seal. Screw nut screw too loose, when installation will leak.
