Oil leakage in mechanical equipment not only wastes oil and pollutes the environment, but also causes the lubricating oil to fail to reach the lubricating parts, thus affecting the service life and working performance of the equipment. Strengthening seal 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, eliminate public hazards, and realize production. Therefore, eliminating oil leakage in mechanical equipment has great practical value.
Causes of oil leakage in mechanical equipment The causes of oil leakage in mechanical equipment include five aspects: design, manufacturing, equipment installation, use, and maintenance. Classification of oil leakage in mechanical equipment Common oil leakage substances in mechanical equipment include: fuel oil, lubricating oil, hydraulic oil, mineral oil and cooling oil.
Oil leakage in the reduction gearbox, leakage in the contact section between the pump shaft and the packing due to wear, leakage in the leakage layer, leakage of the working medium penetrating into the sealing material with poor density and flowing outward or inward, leakage of vacuum with poor density; destructive leakage of the felt ring seal of the reducer shaft due to deterioration of the use conditions, resulting in sharp wear of the seal, or high temperature carbonization, thermal cracking, plastic deformation and fatigue damage, etc., which rapidly increases the leakage gap.
Severe wear, large deformation, aging of seals, and corrosion of seals. Static leakage refers to the leakage between the joint surfaces of two parts without relative motion. Leakage between joint surfaces such as casing, flange, thread, stop, cutting edge, etc. Reciprocating leakage refers to the leakage between the joint surfaces of two parts with relative reciprocating motion. Leakage between the piston rod and packing. Rotary leakage refers to the leakage between the joint surfaces of two parts with relative rotary motion. Leakage between the shaft and the sealing ring.
