Description

Avoid the mechanism of hydraulic jack oil leak
Technical field
The present invention relates to a kind of filter, and in particular to avoids the mechanism of hydraulic jack oil leak.
Background technology
Hydraulic jack is that hydraulic energy is changed into mechanical energy, straight reciprocating motion is done or the hydraulic pressure of oscillating motion performs member Part.Its simple in construction, reliable operation.Realized with it during reciprocating motion, deceleration device can be removed from, and without drive gap, Stable movement, therefore be used widely in various mechanical hydraulic systems.Hydraulic jack power output and piston rod significant surface The pressure difference on product and its both sides is directly proportional;Hydraulic jack is substantially by cylinder barrel and cylinder cap, piston rod and piston rod, sealing device, slow Flushing device is constituted with exhaust apparatus.Buffer unit is with exhaust apparatus depending on concrete application occasion, and other devices are then essential.
The mechanism with certain mass is driven using hydraulic jack in hydraulic system, when hydraulic jack moves to stroke end There is larger kinetic energy during point, such as do not make deceleration processing, with cylinder cap mechanical collision will occur for hydraulic cylinder piston rod, produce impact, Noise, there is destructiveness.To relax and preventing this harm from occurring, therefore deceleration device can be set in hydraulic circuit or in cylinder body Inside set buffer unit.
Hydraulic jack is the executive component that hydraulic energy is converted to in hydraulic system mechanical energy, and its failure can be summarized as substantially Hydraulic jack misoperation, powerless promotion load, piston rod sliding are creeped and oil leak etc..Due to hydraulic jack failure Cause the phenomenon of equipment downtime of common occurrence, therefore, the fault diagnosis and working service that should pay attention to hydraulic jack work.
Generally, the oil leak of hydraulic jack be divided into let out and leak.Internal draining mainly has following reason:
1st, wear ring is damaged, and pulls cylinder sleeve, piston and sealing;
2nd, fatigue or aging are sealed;
3rd, hydraulic oil is dirty, and a large amount of impurity enter oil cylinder, and piston seal is worn and torn and damaged.
The content of the invention
Present invention aims at the mechanism that offer avoids hydraulic jack oil leak, solution hydraulic oil is dirty, and a large amount of impurity enter Oil cylinder, piston seal is worn and torn and damaged, the problem of causing oil cylinder oil leak.
The present invention is achieved through the following technical solutions:
Avoid the mechanism of hydraulic jack oil leak, including right-angle elbow pipe, controller, display and be arranged in right-angle elbow pipe Pressure sensor, connecting pole and screen modules in heart hole,
The right-angle elbow pipe includes pipeline I and pipeline II orthogonal and connect, and the pressure sensor is wireless pressure Force snesor, its one end is arranged on the inwall of pipeline I close to one end of pipeline II, and throwing of the pressure sensor along the axis of pipeline II Shadow falls in the section of pipeline, and the other end of pressure sensor is connected by connecting pole with screen modules;
The screen modules can filter out the liquid for flowing to pipeline II from pipeline I in impurity;
The controller is connected with display, and pressure sensor can sense the pulling force information for coming from connecting pole, and will Its pressure signal sensed is sent to controller, and the controller receives the information for coming from pressure sensor, and is sent out Display is given, the display receives the information for coming from controller, and is shown on a display screen.Controller is preferably single Piece machine, its model is preferably 8C51SL;Display uses LED display or digital display screen.
The present invention is connected with the fuel tank of oil supply oil supply cylinder, and the fluid in fuel tank is pumped into by right-angle elbow pipe by oil pump In, flow back to fuel tank after sequentially passing through pipeline I and pipeline II.It is pumped into as fluid is constantly rushed in fuel tank in right-angle elbow pipe, in fluid Impurity filtered by screen modules, it is to avoid a large amount of impurity enter oil cylinder, and piston seal is worn and torn and damaged, causes oil cylinder oil leak Situation occur.
When oil pump is stopped, the pulling force signal that pressure sensor is received is the impurity weight in screen modules, work The impurity weight amount that people can be shown by observing on display, to determine whether to change screen modules.
When simultaneously in order to avoid cylinder efficient, the impurity filtered on filter screen is back in fuel tank, between pipeline I and fuel tank Check valve is set, makes fluid can only be from fuel tank flow ipe I.
Further, spring is provided between pressure sensor and connecting pole, the spring is cylindrically coiled spring, and Its diameter parallel is respectively positioned on pipeline II in one end on the axis of pipeline II, spring away from pressure sensor and screen modules In.
When oil flow is larger, screen modules can by the larger pulling force along the axial direction of pipeline II, and when connect The section of post receives pulling force, influences the stability between the service life and connecting pole and pressure sensor of connecting pole, therefore set Spring is put, produces deformation to absorb part energy, protection connecting pole and connecting pole by spring when oil flow is larger Connecting portion between pressure sensor.
Further, the screen modules include filter screen and mounting ring, the screen pack along the circumferentially disposed of mounting ring, And cover the centre bore of mounting ring;
Along the diameter of mounting ring, the center of circle of mounting ring is provided with several linking arms, institute to the circumferencial direction of mounting ring State axis centre of the linking arm along mounting ring symmetrically, it is close on one end and linking arm on the connecting pole away from pressure sensor One end of mounting ring is connected, and the axis of connecting pole is overlapped with the axis of mounting ring.
Further, guide pad is provided with the outer wall of mounting ring, guide groove, institute is provided with the inwall of pipeline II State guide groove extension axis parallel to pipeline II axis, the guide pad be located at guide groove in, and can along guide groove axle Line is moved.
Further, reinforcement, one end of the reinforcement and connecting pole are provided between linking arm and connecting pole The connection of side wall, one end away from connecting pole is connected on the other end and linking arm of reinforcement.
Further, in addition to acoustic-optic alarm, the acoustic-optic alarm includes the buzzing being connected with controller Device and LED.When oil pump is stopped, the pulling force signal that pressure sensor is received is the impurity weight on filter screen, works as impurity When more, controller starts acoustic-optic alarm, to remind workman to change filter screen.
Controller, pressure sensor and acoustic-optic alarm in above-mentioned are prior art, can commercially be purchased Buy.
