This paper analyzes the causes of oil leakage of Wood Shredder equipment, expounds the distinguishing methods of oil leakage grades at home and abroad, and probes into the measures for preventing and controlling leakage. The analysis shows that the prevention of oil leakage of Wood Shredder equipment should be controlled from the aspects of structure design, manufacturing process, material selection, pollution control, maintenance and use.
Oil leakage of Wood Shredder equipment not only wastes oil and pollutes the environment, but also affects the service life and working performance of the equipment because the lubricating oil can not reach the lubricating part. Strengthening sealing management can keep the equipment in good condition, effectively improve the operation rate of the equipment, reduce the consumption of water, electricity, gas, oil and materials, reduce pollution and eliminate it. Therefore, it is of great practical value to eliminate the leakage of Wood Shredder equipment. The causes of oil leakage of Wood Shredder equipment include equipment design, manufacture, installation, use and maintenance.
Classification of common oil leakage and leakage grades of 1.Wood Shredder equipment
In Wood Shredder equipment, the leakage material is generally "five oils": fuel oil, lubricating oil, hydraulic oil, mineral oil and cooling oil. Equipment leakage is generally pided into 3 types: oil leakage, dripping oil and flowing oil. Oil penetration: For fixed joints, drop 1 drop of oil every 30 minutes, for movable joints, drop 1 drop of oil every 5 minutes; drop 1 drop of oil every 2-3 minutes; flow oil: drop 5 drops or more per minute. China will generally be pided into serious oil leakage, oil leakage and slight oil leakage 3.
oil leakage per unit time.
Usually it is expressed by 1 h oil leakage (g/ h) or 24 h oil leakage (g/24 h). It can also be represented by mL/ h or mL/ 24 h. For example, ISO06194 4 revolving shaft lip type seal ring Part 4: Performance test method, stipulated that the "qualified test" of the product must use six sealing rings as a group, after the total test time is 240 hours, the maximum allowable leakage of six sealing rings is 12 g, the maximum allowable leakage of a single sealing ring is 3 g. The amount of oil leakage per unit stroke of reciprocating movement is usually expressed as the amount of oil leakage per 100 m (g/100 m) or 1 km (mL/km) per movement.
