Description
Affiliated technical field
The utility model relates to the hydraulic test apparatus field, especially, is a kind of oil hydraulic cylinder tester.
Background technique
The defective meeting of hydraulic cylinder processed finished products causes various leakages, though the leakage on hydraulic cylinder piston both sides can not produce the loss of hydraulic oil, owing to leak, set control action may be affected, until causing the system failure.Hydraulic oil directly leaks in the environment, except meeting influences the working environment of system, also can cause the not enough initiating failure of system pressure.Leak into the danger that hydraulic oil in the environment also has breaking out of fire.So must be behind the oil hydraulic cylinder finished product through pressure test.
The pressure test of oil hydraulic cylinder generally is made up of large-power hydraulic pump and instrument, and complete equipment is expensive, and it is huge to consume energy.
Summary of the invention
To the problems referred to above, the purpose of the utility model is to provide a kind of oil hydraulic cylinder tester, and this oil hydraulic cylinder tester structure is simple, in the time of required less energy consumption bigger pressure can be provided.
The scheme that the utility model technical solution problem is adopted is: this oil hydraulic cylinder tester comprises the pump housing and test splice, and the said pump housing is that an end seals the untight oil hydraulic cylinder of an end, and said oil hydraulic cylinder not closed end is positioned over ground up; Said oil hydraulic cylinder set inside one is the piston of air-tight fit with it; Be full of hydraulic oil in the cylinder body of said piston closes oil hydraulic cylinder, the piston rod of said piston is coaxially arranged with discus on the said piston rod up; Said discus can slide up and down on piston rod; Said discus diameter is less than piston diameter, and said piston rod part is provided with electric capstan, and the twisted rope on the said electric capstan links to each other with discus; Test interface is led to through a pipeline in said oil hydraulic cylinder bottom; Said pipeline is provided with one-way valve, and it is path that said one-way valve gets into test interface by oil hydraulic cylinder, and pressure gauge and valve are arranged on the said test interface.
Further, said piston top is provided with rubber, the impact force of buffering discus.
Further, said piston rod is provided with the impact force scale, convenient adjustment impact dynamics.
The beneficial effect of the utility model is: the electric capstan pulling discus of piston rod part rises, and electric capstan is stopped power supply, and discus falls and piston slap; Piston stress is also pushed hydraulic oil, and hydraulic oil arrives test interface through the one-way valve on the pipeline of oil hydraulic cylinder bottom, and the multiple impact through discus reaches required pressure; Said test interface inserts tested oil hydraulic cylinder, opens the valve on the test interface, and whether observe oil hydraulic cylinder has leakage; After test is accomplished; Can make piston reset through opening one-way valve, pressure solutions is removed, and closes the valve on the test interface; Unload hydraulic jack, the utility model adopts small-power driver and simple relatively equipment to reach identical test pressure.
Description of drawings
Fig. 1 is an embodiment's of this oil hydraulic cylinder tester a structural representation.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified:
In the embodiment shown in fig. 1, this oil hydraulic cylinder tester comprises the pump housing and test splice 13, and the said pump housing is that an end seals the untight oil hydraulic cylinder 1 of an end; Said oil hydraulic cylinder 1 not closed end is positioned over ground up, and said oil hydraulic cylinder 1 set inside one is the piston 2 of air-tight fit with it, is full of hydraulic oil in the cylinder body of said piston 2 confining liquid cylinder pressures 1; The piston rod 21 of said piston 2 up; Be coaxially arranged with discus 22 on the said piston rod 21, said discus 22 can slide up and down on piston rod 21, and said discus 22 diameters are less than piston 2 diameters; Said piston rod 21 tops are provided with electric capstan 23; Twisted rope 24 on the said electric capstan 23 links to each other with discus 22, and test interface 13 is led to through a pipeline in said oil hydraulic cylinder 1 bottom, and said pipeline is provided with one-way valve 3; It is path that said one-way valve 3 gets into test interface 13 by oil hydraulic cylinder 1, on the said test interface 13 pressure gauge 12 and valve is arranged.
Above-mentioned oil hydraulic cylinder tester, said piston 2 tops are provided with rubber, the impact force of buffering discus 22.
Above-mentioned oil hydraulic cylinder tester, said piston rod 21 is provided with the impact force scale, and said discus 22 rises to the pairing impact force scale of different heights, has different momentums when then falling; Convenient adjustment impact dynamics.
When above-mentioned oil hydraulic cylinder tester moved, the electric capstan 23 pulling discuses 22 at piston rod 21 tops rose, and electric capstan 23 is stopped power supply; Discus 22 falls and piston 2 bumps, piston 2 stressed and extruding hydraulic oil, and hydraulic oil arrives test interface 13 through the one-way valve on oil hydraulic cylinder 1 bottom pipe 3; Repeat above-mentioned steps and reach the specified pressure scope up to pressure gauge 12, said test interface 13 inserts tested oil hydraulic cylinder, opens the valve on the test interface 13; Whether have leakage, test can make piston 2 reset through opening one-way valve 3 after accomplishing if observing oil hydraulic cylinder; Pressure solutions is removed, and closes the valve on the test interface 13, unloads hydraulic jack.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
