Required.
1. Aging of large generating equipment: As the use time of the equipment increases, the sealing performance of the equipment will gradually decline, leading to oil leakage problems. Therefore, an oil leak pool must be added. .
2. Improper maintenance of large generator equipment: If the equipment is not properly maintained, such as not replacing the seals for a long time, not replacing the lubricating oil in time, etc., it will cause leakage problems. 'oil. , it is therefore necessary to install an oil leak basin.
3. Unreasonable design of large generator equipment: unreasonable design of equipment, such as unreasonable sealing structure, unreasonable design of lubrication system, etc., will lead to oil leakage problems, leakage pool oil must therefore be defined. up. .
Causesoil leaks in generators
More than 90% of oil leak problems are caused by prolonged exposure of the rubber seal ring to alternating cold and hot temperatures, causing The seal ring loses a large amount of plasticizer. In addition to the softener, there has been a problem with corrosion, aging and hardening. At first it was an oil leak, and gradually oil dripping started to occur. Over time, the sealing ring broke. In the past, oil leaks were resolved by removing the engine oil seal and replacing it. Today, with the development of science and technology, the problem of oil leakage can also be solved without disassembly and repair.
Oil leakage in the connection part of the high pressure oil pipe may be caused by poor sealing of the connecting cone joints of the high pressure oil pipe.high pressure oil pipe, fuel injector and fuel injection pump. . Through inspection, Weifang diesel engine parts, after eliminating the causes of oil leakage in the fuel injection pump and injector, check whether the finished surface of the cold tapping cone of the high pressure oil pipeline meets the requirements of the drawing and if there is any error in the bending size. Due to the vibration of the high pressure oil pipe and the installation stress caused by the bending error of the high pressure oil pipe, it is possible to aggravate the lack of tightness of the cone surface sealing.
In order to ensure the requirements of sealing cone shape and dimensional accuracy, it is recommended to add a finishing process of grinding the cone surface after the pipe connection head d The high pressure oil is formed cold and before the oil pipe is bent. In whatconcerns the accuracy of the size and shape of the cone surface, each high pressure oil pipe generally needs to be ground 0.02-0.05mm to form a complete and accurate cone surface, and some people must be further rectified. than 1.0 mm. It is also necessary to put on a protective cover and store it after cold heading, which can completely solve the problem of bruised parts.
