In this programme when being full of fluid in rod end chamber, the light beam that reflective photoelectric switch sends is scattered weak, and reflective photoelectric switch can not action; When there is air in fluid, light beam through air, and is received by reflective photoelectric switch under the reflection of optical reflecting layer on the piston rod, and reflective photoelectric switch action, air is discharged from exhaust ports according to setting by staff manually or automatically.
In order to realize automatic vent, further, described jack-up hydraulic ram has hydraulic control system, and described ball valve is Solenoid ball valve, and described hydraulic control system is connected with reflective photoelectric switch signal with Solenoid ball valve respectively,
When in this programme, reflective photoelectric switch detects in fluid and there is air, reflective photoelectric switch action, sends signal feed back to hydraulic control system, sends SC sigmal control ball valve open by hydraulic control system, and according to arranging automatic vent.
Preferably, described optical reflecting layer is chromium coating, and the reflectivity of chromium is good, and nondiscolouring is corrosion-resistant, and chromium coating has very high hardness, can increase the intensity of piston rod, and the friction factor of chromium coating is little, therefore can increase the working life of piston rod.
Preferably, the direction of described reflective photoelectric switch transmitted beam and the axes normal of described piston rod, can reach better Detection results.
Preferably, described reflective photoelectric switch and ball valve lay respectively at the both sides of described cylinder barrel, the axis of described relief opening and the dead in line of described mounting hole.
Preferably, described relief opening is positioned at the one end near cylinder cap on cylinder barrel, and general air can converge in the top of rod end chamber, and relief opening is arranged near cylinder cap place, is convenient to exhaust.
The beneficial effects of the utility model are: automatic vent dredging vessel jack-up hydraulic ram of the present utility model utilizes when in fluid during entrained air, the light that reflective photoelectric switch occurs can be reflected by the chromium coating of piston rod, feed back to hydraulic control system immediately, Solenoid ball valve is opened by hydraulic control system, and carry out automatic vent according to setting, the utility model can get rid of the potential safety hazard that in oil cylinder fluid, entrained air brings in time, improve the Safety performance of oil cylinder greatly, and add intensity and the working life of piston rod.
