Description
Technical field
The utility model relates to Diesel Fault Diagnosis field, especially a kind of marine diesel lubricating oil moisture early warning
Device.
Background technique
When diesel engine operates, due to the relative motion and contact of piece surface, friction, abrasion are inevitably generated.
Lubricating oil in lubricating system of diesel oil engine has the weights such as anti-attrition cooling anticorrosion, cleaning and sealing as lubrication and cooling medium
It acts on, contains whole tribology information.Due to caused by lubrication failure part failure by wear be in machinery most often
See, most important failure mode, accounts for the 80% of mechanical failure failure.Water when water inlet failure occurs for lubricating system in lubricating oil
It is point exceeded that oil ageing can be accelerated rotten, its oil film Forming ability is destroyed, lubricating oil is made to be deteriorated the lubricant effect of machine,
Accelerate the organic acid generated that can cause to corrode to metal equipment；Moisture also results in emulsification of lubricant and then adsorbs fine particle and produces
Raw sediment, can make the additive in lubricating oil that hydrolysis occur and the generation precipitating that fails, and block oil circuit, influencing lubricating oil just
Often circulation and supply.Meanwhile when the abrasive grain quantity in lubricating oil increases to certain numerical value and replaces not in time, mill is also resulted in
Damage aggravation.Being monitored by state of the real-time monitoring oil quality to machine can be in early detection failure, and to its failure
Reason, position etc. are analyzed, and realize condition maintenarnce.In addition, lubrication oil value in large ship dynamical system usually all mistake
Million, the failures such as lubricating system water inlet are found in time, can be extended Working Life of Lubricating Oil, be substantially reduced shipping transport cost.But

But device, data processing module etc. form.The system can monitor the variation of machine oil integrated quality on-line, and use multisensor
Information fusion technology comprehensive analysis oil conditions show oil conditions information by display, issue warning signal when necessary.
Its monitoring parameters is comprehensive, and has built standard environment, and testing result accuracy is higher, readable strong, professional to object is used
Acquisition of knowledge degree requires complexity that is low, but also therefore increasing system, control and measurement conversion built in measurement and control host computer
Program is complicated；Liquid level sensor, oil bath temperature sensor, probe temperature sensor, pressure sensor, balanced flow has been used to pass
The multiple equipments such as multiple sensors such as sensor and sampler, oil bath case, heater, constant flow pump, system self maintained requirement height,
Manufacturing cost is high.Although being used for the machine oil quality on-line monitoring system combined of multi-sensor information of automobile engine in this application
Real time on-line monitoring is realized, detection parameters are comprehensive, but while directly applying to spot ship diesel engine need to be to lubricating system even
It is that diesel engine body does very big change.
