Description
Technical field
The utility model relates to technical field of hydraulic oil cylinder, especially relates to a kind ofly having the hydraulic jack of monitoring oily leakage function.
Background technique
Hydraulic energy is changed into mechanical energy, does the hydraulic actuator of straight reciprocating motion (or oscillating motion) by oil hydraulic cylinder.Its structure is simple, reliable operation.When realizing to-and-fro motion with it, can speed reducer be removed from, and there is no drive gap, stable movement, therefore be used widely in the hydraulic system of various machinery.The pressure reduction on oil hydraulic cylinder ouput force and piston effective area and both sides thereof is directly proportional; Oil hydraulic cylinder is made up of cylinder barrel and cylinder cap, piston and piston rod, seal arrangement, damping device and venting gas appliance substantially.Damping device and venting gas appliance are depending on embody rule occasion, and other devices are then essential.
But existing oil hydraulic cylinder there will be in hydraulic system and enters air, mainly occur because have in system to leak.Now should check the liquid level of hydraulic oil container, the Sealing of oil hydraulic pump intake side and pipe joint, whether oil suction strainer is too dirty.If so, answer replenisher force feed, process sealing and pipe joint, cleaning or replacing coarse filter element, but check whether that leaking is a very difficult thing, therefore covers the shortage in requisition for the method finding out a simple and fast.
Model utility content
The technical problems to be solved in the utility model is: checking the problem of hydraulic system leakage to overcome inconvenience in prior art, providing a kind of and having the hydraulic jack of monitoring oily leakage function.
The utility model solves the technological scheme that its technical problem adopts: a kind of have the hydraulic jack of monitoring oily leakage function, comprise hydraulic jack, flow monitor, stroke detector and controller, the filler opening of described hydraulic jack fixedly mounts flow monitor, described hydraulic jack end winding support installs stroke detector, described stroke detector is connected with the plunger rod contacts of hydraulic jack, described flow monitor is all connected with controller signals with stroke detector, normal hydraulic jack, the movable length of oil inlet quantity and piston rod can be regarded as, the shift motion of the oil inlet quantity and hydraulic cylinder piston rod that therefore detect hydraulic jack can detect the problem whether hydraulic jack has leakage effectively.
In order to more effectively measure the survey leakage position of hydraulic jack, the oil outlet of described hydraulic jack is installed with the second flow monitor, described second flow monitor signal connection control device.
Bring problem in order to avoid hydraulic jack leaks, therefore need the very first time to inform staff, described controller signals connects warning device.
When oil is after the filler opening of hydraulic jack enters hydraulic jack, flow monitor detects oil inlet quantity, while oil enters oil cylinder, piston rod moves forward, and the stroke of piston rod is detected by stroke detector, flow monitor and stroke detector are by the data information transfer of detection to controller, and controller is compared, if find mistake after comparison, warning is informed staff by alarm.While piston rod reach, oil flows out from oil outlet, after the second flow monitor detects, data is passed to controller.Controller can draw by comparison oil inlet quantity and piston rod stroke, oil inlet quantity and oil pump capacity the approximate location that hydraulic jack leaks, that is: when the stroke of movement needed for oil inlet quantity and piston has error, oil pump capacity is equal with oil inlet quantity, then leak position should be between oil outlet and piston; When the stroke of movement needed for oil inlet quantity and piston is error free, if oil pump capacity is less than oil inlet quantity, then leak position should be between piston and oil outlet.
The beneficial effects of the utility model are: whether the utility model can detect hydraulic jack easily and leak, and timely leakage problem can be fed back to staff, avoid because hydraulic jack leaks the series of problems caused, improve working efficiency, save the operating time.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is two-dimensional representation of the present utility model.
In figure; 1. hydraulic jack, 2. flow monitor, 3. stroke detector, 4. controller, 5. filler opening, 6. piston rod, 7. oil outlet, 8. the second flow monitor, 9. warning device, 10. piston.
Embodiment
The utility model is described in more detail by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1 a kind of has the hydraulic jack of monitoring oily leakage function, comprise hydraulic jack 1, flow monitor 2, stroke detector 3 and controller 4, the filler opening 5 of described hydraulic jack 1 fixedly mounts flow monitor 2, described hydraulic jack 1 end winding support installs stroke detector 3, described stroke detector 3 contacts with the piston rod 6 of hydraulic jack 1 and connects, described flow monitor 2 and stroke detector 3 are all connected with controller 4 signal, normal hydraulic jack 1, the movable length of oil inlet quantity and piston rod 6 can be regarded as, therefore the shift motion detecting the oil inlet quantity of hydraulic jack 1 and the piston rod 6 of hydraulic jack 1 can detect the problem whether hydraulic jack 1 has leakage effectively.
In order to more effectively measure the survey leakage position of hydraulic jack 1, the oil outlet 7 of described hydraulic jack 1 is installed with the second flow monitor 8, described second flow monitor 8 signal connection control device 4.
Bring problem in order to avoid hydraulic jack 1 leaks, therefore need the very first time to inform staff, described controller 4 signal connects warning device 9.
When oil is after the filler opening 5 of hydraulic jack 1 enters hydraulic jack 1, flow monitor 2 detects oil inlet quantity, while oil enters oil cylinder, piston rod 6 moves forward, and the stroke of piston rod 6 is detected by stroke detector 3, flow monitor 2 and stroke detector 3 are by the data information transfer of detection to controller 4, and controller 4 is compared, if find mistake after comparison, warning is informed staff by alarm.While piston rod 6 moves forward, oil flows out from oil outlet 7, after the second flow monitor 8 detects, data is passed to controller 4.Controller 4 can draw by comparison oil inlet quantity and piston rod 6 stroke, oil inlet quantity and oil pump capacity the approximate location that hydraulic jack 1 leaks, that is: when the stroke of oil inlet quantity and the required movement of piston 10 has error, oil pump capacity is equal with oil inlet quantity, then leak position should be between oil outlet 7 and piston 10; When the stroke of movement needed for oil inlet quantity and piston 10 is error free, if oil pump capacity is less than oil inlet quantity, then leak position should be between piston 10 and oil outlet 7.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this model utility technological thought, can carry out various change and amendment completely.The technical scope of this model utility is not limited to the content on specification, must determine its technical scope according to right.
