In the instruction manual of the equipment, generally for each lubrication parts are filled with lubricant detailed requirements. But in the actual use of the investigation found that some maintenance personnel tend to ignore the above requirements. Production of several common equipment lubrication errors:
01 Need lubrication? Add a little oil!
Due to the differences in the way each part of the equipment works and the state in which it is located, and thus the refueling cycle for each lubrication point, the amount of oil filled each time and the way of filling have strict requirements, maintenance personnel should be strictly enforced in accordance with the requirements, and can not be arbitrarily added a little bit of oil to do the job, so it is difficult to meet the requirements of lubrication.
02 has been added to the oil, still owe lubrication?
The moving parts of the equipment, the working mode and the different ambient temperatures, the lubricant requirements are different, should be required to add different kinds of lubricants of different grades. Only the use of necessary additives, with the required physical and chemical indicators of the lubricant, in order to make the equipment to get a good lubrication, do not look at the brand randomly refueling is to be bad.
03 Add more lubricants, no harm?
Equipment running parts of the structure of the form and the use of conditions to determine the amount of refueling, usually in the instruction manual of the equipment have clear provisions and requirements. Maintenance should be based on the instruction manual, equipment configuration of the oil label or dipstick and window and other appropriate amount of supplement, overfill lubricants, it is harmful.
04 After adding lubricating oil, it dries quickly!
Strictly speaking, this is a misunderstanding of the concept, only the fuel is directly involved in the work. Add lubricant, generally refers to the lubricant added to the mutual movement of the friction between the friction between the vice, with which to fill the bumps and maintain a certain thickness of the lubricant film, to achieve the friction between the vice of the two surfaces in contact with each other, reduce frictional resistance, reduce wear and tear, while also cooling the machine parts and sealing effect. These effects of refueling are indirectly supporting the fuel work.
05 Oil leak, change the seal?
In most cases in hydraulic systems, oil leakage failures are the result of seal failure. The seal acts as an elastic (pressure) seal.
After the seal is installed in place, its elasticity should be able to have pre-pressure on the contact surface when there is no oil pressure, i.e., its cross-section should have a certain compression deformation; when there is oil pressure, it is pressed to the side of the groove by the elasticity and so on to play a sealing role. Replacement of the sealing ring, must be strictly in accordance with the instructions to select the same size of the sealing ring, otherwise it can not ensure that the appropriate degree of compression and other requirements.
At the same time, special attention should be paid to: should not have been used sealing ring, but with the new sealing ring should be carefully checked its surface quality, in the confirmation of no small holes, protrusions, cracks and grooves and other defects and have sufficient elasticity before use. Oil leakage, sloppy replacement of a seal is sure to be a mistake.
06 Seal type is good, just put it on?
Replacement of seals, the hydraulic system should first be opened to the parts of the strict cleaning, and strictly prevent impurities, dirty oil mixed into the system. When installing, it is better to use special tools to prevent metal sharp edges or even finger nails to scratch it. Never allow the sealing ring directly over the threaded parts of the components, under special circumstances should be self-made simple installation tools or application of plastic film wrapped around the threaded parts, and in the tool or film coated with clean hydraulic oil of the same type. "Sleeve on the line" is essentially not.
07 spare seals, just put on the line?
Because the seal contains more additives, easy to age and deteriorate. Therefore, in the preservation of both to avoid sunlight, but also to prevent it from moisture and heat, but also pay attention to acid, alkali substances can not be contacted, usually do not store more than a year and a half of the preservation period. They should not be kept by hanging them on a string or wire. Therefore, it is not acceptable to leave the spare seals lying around.
08 Oil is dirty, pour it out!
In addition to the hydraulic oil has been rancid deterioration of the hydraulic oil, there are more hydraulic oil and lubricating oil can still be used. Simply mixed with metal particles of hydraulic oil, after precipitation and filtration can also be reused. Heavier contamination of the fluid after simple treatment, can be used as roughing equipment lubrication and open-air equipment rust use, or will be collected on the waste oil surrendered for waste oil regeneration use, so you can save energy and reduce waste. And "a dump it" although save trouble but pollute the environment, contrary to the principle of sustainable development.
