Description
Technical field
The utility model relates to a kind of oil cylinder detection device, specifically belongs to the device that a kind of energy on-line checkingi oil cylinder Inner lets out.
Background technique
Compressing cylinder is industrially widely used as actuator.Letting out in oil cylinder is a ubiquitous problem, problems such as exceeding specified value if let out in oil cylinder, easily cause hydraulic jack to slow, transport power is not enough, action is steady, abnormal operation, dynamic performance change, system oil temperature rise is high.
With regard to present circumstances, oil cylinder is let out in occurring, owing to can not directly observe, therefore causes fault very hidden by it, judges comparatively difficulty; Meanwhile, a lot of oil cylinder, because volume is comparatively large, mounting point is complicated, if error in judgement, will affects normal production, and pay meaningless work and time owing to dismantling oil cylinder.
Oil cylinder Inner conventional at present lets out detecting method to be had:
1, keep oil hydraulic cylinder one chamber oil-feed, make oil cylinder stop a certain end position, another chamber oil pipe is opened, observe fluid discharge, or;
2, oil cylinder is vertically parked in certain position, carries out mark, record variable quantity in observation place after a period of time.
The deficiency that first method exists is the oil supply source needing to continue, and need dismantle oil pipe, must guarantee site safety during plus-pressure; The deficiency that second method exists is equipped with requirement to oil cylinder installation position, and hyperbaric chamber need have pressurize element, needs to guarantee to enter hyperbaric chamber without oil simultaneously.
Model utility content
The purpose of this utility model is to overcome that prior art exists needs oil supply source, and oil pipe need be dismantled or requirement is equipped with to oil cylinder installation position, hyperbaric chamber need have pressurize element, need to guarantee to enter the deficiencies such as hyperbaric chamber without oil simultaneously, there is provided one can online quick, easy, detect in oil cylinder and let out situation accurately, safely, and can the device let out of on-line checkingi oil cylinder Inner without the need to dismantling oil cylinder and increasing a kind of of complex components.
Realize the technical measures of above-mentioned purpose:
The device that a kind of energy on-line checkingi oil cylinder Inner lets out, it is: it is primarily of rod chamber detecting tube, rodless cavity detecting tube, oil pressure gauge, cut-off valve that rod chamber detecting tube and rodless cavity detecting tube connect respectively, the selector valve be connected between rod chamber detecting tube with rodless cavity detecting tube, the oil collector be provided with below rod chamber detecting tube forms; Rod chamber detecting tube is connected with the rod chamber of oil cylinder, and rodless cavity detecting tube is connected with the rodless cavity of oil cylinder.
It is characterized in that: on rod chamber detecting tube, safety valve is housed.
Feature of the present utility model: can online quick, easy, detect in oil cylinder and let out situation accurately, safely, and without the need to dismantling oil cylinder and increasing complex components.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-rod chamber detecting tube, 2-rodless cavity detecting tube, 3-oil pressure gauge, 4-cut-off valve, 5-selector valve, 6-oil collector, 7-safety valve.
Embodiment
Be described further below in conjunction with accompanying drawing:
The device that a kind of energy on-line checkingi oil cylinder Inner lets out: it is primarily of rod chamber detecting tube 1, rodless cavity detecting tube 2, the oil pressure gauge 3 that rod chamber detecting tube 1 and rodless cavity detecting tube 2 connect respectively, cut-off valve 4, the selector valve 5 be connected between rod chamber detecting tube 1 with rodless cavity detecting tube 2, the oil collector 6 be provided with below rod chamber detecting tube 1 forms; Rod chamber detecting tube 1 adopts plug-in type or rapid pipe joint to be connected with the rod chamber of oil cylinder, and rodless cavity detecting tube 2 adopts plug-in type or rapid pipe joint to be connected with the rodless cavity of oil cylinder.
Separately on rod chamber detecting tube 1, safety valve 7 is housed.
It should be noted that the utility model can be connected on oil cylinder for a long time, observe oil cylinder whether have leakage of oil situation in time to make operator; Also the whether leakage of oil of detection oil cylinder is carried out after can being connected with oil cylinder where necessary.
Cleaning Principle:
Close all cut-off valves and comprise cut-off valve 4 on the utility model, and be connected with the rod chamber of oil cylinder by rod chamber detecting tube 1, rodless cavity detecting tube 2 is connected with the rodless cavity of oil cylinder; Confirming there is hydraulic lock during oil cylinder this and all pipelines, valve etc. that are connected with oil cylinder are without any external leakage and oil hydraulic circuit, cylinder piston rod is moved to an end position; Open the cut-off valve 4 on rod chamber detecting tube 1, and the selector valve 5 between rod chamber detecting tube 1 and rodless cavity detecting tube 2, the rod chamber of oil cylinder and rodless cavity internal pressure are let out, namely until flow out without fluid; Then the selector valve 5 between cut-off valve 4 on rod chamber detecting tube 1 and rod chamber detecting tube 1 and rodless cavity detecting tube 2 is closed; Open the cut-off valve 4 on rodless cavity detecting tube 2 again, the oil pressure gauge 3 on observation rodless cavity detecting tube 2; After making the rodless cavity of oil cylinder have certain pressure, close the cut-off valve 4 on rodless cavity detecting tube 2, observe rodless cavity internal pressure and whether decline: if pressure does not decline, then prove that oil cylinder is let out without interior, detect and terminate; If pressure drop, then open the cut-off valve 4 on rodless cavity detecting tube 2 and the selector valve between rod chamber detecting tube 1 and rodless cavity detecting tube 25, make rod chamber and rodless cavity internal pressure equal; Close the cut-off valve 4 on rodless cavity detecting tube 2 again, observe pressure and whether decline, if pressure still declines, then close the selector valve 5 between rod chamber detecting tube 1 and rodless cavity detecting tube 2, now, let out in the hydraulic lock in the chamber that pressure drop is fast or cut-off valve have, must process; If pressure does not decline, prove that oil cylinder itself is let out in having, now close the selector valve 5 between rod chamber detecting tube 1 and rodless cavity detecting tube 2, and open the cut-off valve 4 on rodless cavity detecting tube 2 and the cut-off valve 4 on rod chamber detecting tube 1; When the lower exit port on rod chamber detecting tube 1 fuel-displaced stable time, start to record oil pump capacity and timing, finally oil pump capacity to be drawn under test pressure discharge in oil cylinder divided by the time, after having detected, dismounting detection device, recovers original system.
This embodiment is only the best and exemplifies, the restricted enforcement not to technical solutions of the utility model.
