1. The pressure in the fuel tank rises
In a closed reducer, each pair of gears meshing and friction will generate heat. According to Boyle Mario’s law, as the operating time increases, the temperature in the reducer will gradually increase, and the volume inside the reducer No change, so the pressure in the box will increase accordingly, and the lubricating oil in the box will be splashed and spilled on the inner wall of the reduction box. Due to the relatively strong oil permeability, under the pressure in the tank, where the seal is not tight, the oil will seep out from there.
2. The unreasonable structure design of the reducer causes oil leakage
If the reducer is designed without a vent cover, the reducer cannot achieve pressure equalization, causing the pressure in the box to become higher and higher, and oil leakage occurs.
3. Too much fuel
During the operation of the reducer, the oil pool is greatly agitated, and the lubricating oil splashes everywhere in the machine. If the amount of oil is too much, a large amount of lubricating oil will accumulate on the shaft seal, joint surface, etc., resulting in leakage.
4. Improper maintenance process
During equipment maintenance, due to incomplete removal of dirt on the joint surface, improper selection of sealant, reverse installation of the seal, and failure to replace the seal in time, oil leakage may also occur. The use of polymer composite materials to repair and control the oil leakage of the reducer. The polymer composite materials are made of polymer, metal or ceramic ultra-fine powder, fibers, etc. as the base material, and are compounded under the action of a curing agent and a curing accelerator s material. Various materials complement each other in performance and produce a synergistic effect, so that the comprehensive performance of the composite material is better than that of the original composition material. With strong adhesion, mechanical properties, and chemical corrosion resistance, it is widely used in the repair of mechanical wear, scratches, pits, cracks, leakage, casting sand holes, etc. of metal equipment, as well as various chemical storage tanks , Chemical anti-corrosion protection and repair of reaction tanks and pipelines. question. If the static sealing point of the reducer leaks oil during operation, the oil surface emergency repair agent of surface engineering technology can be used to stick to the plug, so as to achieve the purpose of eliminating the oil leakage.
Treatment plan
1. Use polymer composite materials to repair and control the oil leakage of the reducer. The polymer composite materials are based on polymer, metal or ceramic ultrafine powder, fibers, etc., and are compounded under the action of curing agents and curing accelerators. Made of materials. Various materials complement each other in performance and produce a synergistic effect, so that the comprehensive performance of the composite material is better than that of the original composition material. With strong adhesion, mechanical properties, and chemical corrosion resistance, it is widely used in the repair of mechanical wear, scratches, pits, cracks, leakage, casting sand holes, etc. of metal equipment, as well as various chemical storage tanks , Chemical anti-corrosion protection and repair of reaction tanks and pipelines. If the static sealing point of the reducer leaks oil during operation, the oil surface emergency repair agent of surface engineering technology can be used to stick to the plug, so as to achieve the purpose of eliminating the oil leakage.
2. New lubricants can be used to solve the problem of oil leakage at the sealing part. Among many materials, the better application effect is Metre sealant lubricant, which has self-lubricating properties and reduces the gap between the meshing parts. , Effectively alleviate the problem of equipment noise and oil leakage at the dynamic seal part. Lubricant is an oil additive that will not pollute or deteriorate the oil. It solves the hidden safety hazards in production without stopping the machine, and saves the company high maintenance or replacement costs.
