It sets.
Background technology
Plunger hydraulic pump is a kind of dynamical element of hydraulic system, it mechanical energy can be changed into hydraulic energy from
And pressure oil liquid is provided to hydraulic system, it is the energy source device of hydraulic system.With reference to Fig. 2, equipped with plunger hydraulic
In the hydraulic system of pump 1 ', plunger hydraulic pump 1 ' obtains hydraulic oil by inlet line 2 ' from hydraulic station fuel tank 3 ', and passes through
Oil outlet pipe 4 ' provides hydraulic oil to hydraulic system.Due to having a small amount of hydraulic fluid leak when plunger hydraulic pump 1 ' works,
Drain line 5 ' there are one being also connected between plunger hydraulic pump 1 ' and hydraulic station fuel tank 3 '.
Plunger hydraulic pump 1 ' has a small amount of hydraulic oil and leaks to low pressure chamber from its internal high pressure chest in normal work,
The hydraulic oil for leaking to low pressure chamber flows into fuel tank through connecting plunger hydraulic pump 1 ' and the drain line 5 ' of hydraulic station fuel tank 3 ' again.With
The gradually abrasion of 1 ' inner sealing width of plunger hydraulic pump, the leakage rate of internal hydraulic pressure oil also incrementally increases.Due to drain mast
Road 5 ' is closed, and maintenance personal can not have found the variation of 1 ' internal leakage amount of plunger hydraulic pump and in time in time to wearing more
Serious plunger hydraulic pump 1 ' is replaced.Therefore the thorough wear out failure of plunger hydraulic pump 1 ' is often caused, a large amount of abrasions
Grain enters hydraulic system and paralyses so as to cause hydraulic system；Or 1 ' shell inner fluid pressure of plunger hydraulic pump is caused to permit more than it
Perhaps range damages the oil sealing at pump shaft, causes a large amount of oil leaks.Therefore, we provide a kind of plunger hydraulic pump leakage monitor.
Invention content
The utility model provides a kind of plunger hydraulic pump leakage monitor, to solve existing plunger hydraulic pump because can not
It monitors its internal hydraulic pressure oil leakage quantity and finds hydraulic pump inter deterioration in time and carry out preventative maintenance hydraulic pressure to caused by
The problems such as pumping oil accident.
The utility model adopts the following technical solution：
A kind of plunger hydraulic pump leakage monitor, including oil path block and pressure gauge, the oil path block are mounted on plunger liquid
On drain line between press pump and hydraulic station fuel tank, which is internally provided with a threeway oil circuit, the threeway oil circuit
Equipped with first interface, second interface and third interface, the first interface is connect with drain line, the second interface and hydraulic pressure
Fuel tank of standing connects, and the third interface is connect with the pressure gauge.
Further, further include a pressure meter switch, the pressure gauge is connect by the pressure meter switch and the third
Mouth connection.
Further, the first interface is connect by First Transition pipe fitting with the drain line, and described second connects
Mouthful connect with the hydraulic station fuel tank by the second transition pipe joint, the third interface by third transition pipe joint with it is described
Pressure meter switch connects.
By the above-mentioned description to the utility model structure it is found that compared to the prior art, the utility model has following excellent
Point：
On the draining pipeline that the utility model is arranged between plunger hydraulic pump and hydraulic station fuel tank.In plunger hydraulic pump work
When making, the variation of plunger hydraulic pump internal leakage amount can be obtained in real time by the pressure value variation of pressure gauge on drain line, and
The inter deterioration situation of Shi Faxian hydraulic pumps simultaneously carries out preventative maintenance, avoids largely to grind because of plunger hydraulic pump wear out failure
Damage particle enters hydraulic system, is more than its permission model so as to cause hydraulic system paralysis or plunger hydraulic pump case inner fluid pressure
It encloses and then squeezes a large amount of oil leaks caused by the oil sealing at bad plunger hydraulic pump shaft.The utility model can be to the drain mast in hydraulic system
The hydraulic fluid leak situation on road carries out on-line checking, and the scope of application is big, and application prospect is wide.
Description of the drawings
Fig. 1 is the scheme of installation of the utility model.
Fig. 2 is the schematic diagram for not installing the utility model.
Specific implementation mode
Illustrate specific embodiment of the present utility model with reference to the accompanying drawings.
A kind of plunger hydraulic pump leakage monitor, referring to Fig.1, including oil path block 1 and pressure gauge 2, oil path block 1 are mounted on
On drain line 5 between plunger hydraulic pump 3 and hydraulic station fuel tank 4.Oil path block 1 is internally provided with a threeway oil circuit, this three
Logical oil circuit is equipped with first interface, second interface and third interface, and first interface is connected by First Transition pipe fitting and drain line 5
It connects, second interface is connect by the second transition pipe joint with hydraulic station fuel tank 4.The plunger hydraulic pump leak detecting device further includes
One pressure meter switch 6, pressure gauge 2 are connect by the pressure meter switch 6 with third interface, and third interface is connect by third coupling tube
Head is connect with pressure meter switch 6.
At work, pressure meter switch 6 is opened for plunger hydraulic pump 3.Plunger hydraulic pump 3 is by inlet line 7 from hydraulic pressure
It stands and obtains hydraulic oil in fuel tank 4, and hydraulic oil is provided to hydraulic system by oil outlet pipe 8.Plunger hydraulic pump 3 is gone back at work
There is a small amount of hydraulic oil that can leak to low pressure chamber from 3 internal high pressure chamber of plunger hydraulic pump, leaks into the hydraulic oil of low pressure chamber along
One interface leak is to drain line 5.Drain line 5 is equipped with oil path block 1, and the third interface of the oil path block 1 passes through third transition
Pipe fitting is connect with pressure meter switch 6, and a pressure gauge 2 is also connected on pressure meter switch 6, which can be with real-time display
Pressure value in drain line 5.When the leakage rate of plunger hydraulic pump 3 internal hydraulic pressure oil increases, the numerical value of pressure gauge 2 will appear
Corresponding variation, the numerical value change by reading pressure gauge 2 can find the abrasion condition inside plunger hydraulic pump 3 in time, and
The plunger hydraulic pump 3 for wearing more serious is replaced.
