1, axle bearing do I need to lubricate?
Because of NSK bearings working methods and the status differences, thus, for refuelling cycle of the lubrication points, each charging oil and raise and other strict requirements, driving, maintenance staff should be demands the strict implementation of, not something feel free to add a little oil, such a requirement is difficult to meet the NSK bearing lubrication.
2, NSK bearings are often the oil, do you still owe lubrication?
NSK bearing parts of the movement, how they work and the ambient temperature of the different, has a different requirement for lubricant, should raise a variety of different brands of lubricants as required. Only contains the necessary, has the required physical and chemical indexes of lubricant additives, to make them get a good lubrication, not waiting for the brand casual refuelling is a bad thing.
3, add more Lube, no harm.
Equipment structure and usage of the site decided to refuel the largest number, usually in the instructions for use of the device has specific requirements and requests. Maintenance shall be according to the instructions for use, equipment configuration feet and Windows in the right amounts of oil or oil added that excessive to add oil, is counter-productive.
4, after lubricating, dry faster!
Strictly speaking, this is a misunderstanding on the conceptual understanding, only fuel directly to participate in features. Lubricating the generally refers to add lubricating oil to each other between friction pairs, fill them up with its bump, and maintain a certain thickness of the lubricating oil film, meet separated by friction between two surfaces in contact, lower friction, reduced wear and tear of purpose, along with cooling parts and seals. Filling these roles indirectly supporting function of fuel.
5, oil spills, and change the seals.
In the hydraulic system, in most cases the oil spill failure is the result of seal failure. Sealing ring is elastic (pressure), have airproof effect.
Sealing ring installation in place, when there is no oil pressure the elastic should be able to contact surface pressure, namely its section there should be a certain compression deformation; when there is oil pressure, it was pressure to the grooved side elastic played a role. When you replace the sealing rings must be strictly in accordance with the manual selection of seals of the same size, otherwise it cannot guarantee their proper pressure tightness requirements. At the same time, special attention should be paid: not apply seals have been used, and when a new sealing ring should also carefully examine the surface quality, affirms that a small hole, wart, defects such as cracks and grooves and sufficient flexibility must be used. Oil spills, careless changing a sealing ring is sure to delays.
6, seals good models, sets on the line.
When you replace the sealing ring, should strictly open hydraulic system parts cleaning, and take strict precautions against impurity, dirty oil mixing system. When you install, it is better to use special tools to prevent the sharp edges of metal fingernail scratches it even. Sealing rings should never be allowed direct set of components the threaded parts, special cases should be made easy to install appliances or apply a plastic film wrap threaded parts, and tools on outer coating or membrane cleaning of the same types of hydraulic oil. "On the line" is essentially no.
7, spare sealing rings, casually stood on the line.
Due to the seal ring contain more additives, can aging metamorphose. Therefore, at save time as well as avoiding the rays of the Sun, but also prevents it from moisture and heat, also note cannot be exposed to acids, alkali substances, are usually stored for not more than 1.5 years of shelf life. Not with a rope or wire hanging them up to save. Therefore, alternate seals stands is just not okay.
8, oil is dirty, pour it!
In addition to hydraulic oil Rancidity in metamorphic, and also more hydraulic oil and lubricating oil can still be used. Hydraulic oil is only mixed with metal particles, sedimentation and filtration and can be reused. After simple handling, the more polluting heavy oil that can be used as roughing antirust used equipment lubrication and open device, or waste oils collected to surrender for the regeneration of waste oils to use, so as to save energy and reduce waste. "One down" while the easy but polluted the environment, contrary to the principles of sustainable development.
