Design Of High Efficency Essential Oil Filter And On-line Detection And Monitoring

The hydraulic system is composed of power element,actuator,control element and hydraulic oil.Hydraulic system is divided into two categories:hydraulic transmission system and hydraulic control system.The main function of Hydraulic transmission system is to transfer power and movement.Hydraulic control system is to make the hydraulic system output specific performance requirements,generally hydraulic system refers mainly to the hydraulic transmission system.As a major part of hydraulic system,hydraulic oil plays a significant role in the hydraulic system,like transferring energy,cleaning system,abstracting heat etc.Its property can seriously affect the operational reliability and service life of hydraulic equipment.Once the hydraulic oil is polluted with the external and internal influence,it will spread into the whole system,causing a series of domino effect,and finally bring on the malfunction of hydraulic system and components frequently.In order to prevent this situation happens,enhance the operating reliability of the hydraulic system,this article proposes a series of measures to control the pollution by analysing the types of pollutants in the hydraulic system,the characteristics of solid particles,the generation of pollutants and the harm caused by oil contamination.Filter is the only pollution control component in the hydraulic system.In order to maintain the cleanliness of the hydraulic system,the filter must be reliable.Though devising the structure and choosing the material,we designed a high efficiency oil filter performing stable and reliable with long service life based on actual needs,combined with the advanced research achievements home and abroad.This filter can be installed in any circuit of hydraulic system,preventing hydraulic system from the oil pollution,escorting for the hydraulic system if necessary.In order to real-time monitoring the oil contamination degree of hydraulic system,we selected the online automatic particle counter synthesizing technology at home and abroad.Combining this technology with our oil filter,we designed and added oil liquid pollution controlling&the online detection and monitoring system on thehydraulic system,realized the automation,intelligentization and informationization,achieved implementation of the proactive maintenance,reduced the maintenance cycle,provided effective protection and ensured the operating stability and reliability of the hydraulic system.
