Description
Technical field
Test detecting equipment field is the utility model is related to, particularly a kind of fork truck radiator impulse test device.
Background technology
Pressure be present in starting and running accelerator in engine, gearbox during normal use in fork truck radiator
Pulse, how to ensure that fork truck radiator will not be ruptured due to pulse in use causes leak oil leak and interior leakage
Problem, then need to carry out pulsating fatigue experiment to it, so as to verify the service life of fork truck radiator and intensity.And fork truck is scattered
Hot device normally simply carries out related heat dispersion and pressurize ability is verified, pulse testing and without.If to radiating
Horizontal pulse checking is entered in device entrucking, then is had the following disadvantages：1st, experiment process needs truck driver long-time operation vehicle to carry out；Labor
Fatigue resistance is big, and cannot be guaranteed the stability of experiment；2nd, the cost for installing complete vehicle test is higher.
Utility model content
The purpose of this utility model is to provide a kind of fork truck radiator impulse test device, realizes and individually fork truck is radiated
Device carries out pulse testing.
To solve the above problems, the utility model uses following technical scheme：
A kind of fork truck radiator impulse test device, including radiator, in addition to hydraulic oil container, variable-frequency motor, gear pump
And electromagnetism support valve；Cleaner is provided with the hydraulic oil container, the cleaner is connected by the import of fuel sucking pipe and gear pump
Connect, the gear pump electrically connects with variable-frequency motor, and the outlet of gear pump supports the P mouths of valve to be connected by flowline with electromagnetism, institute
The A mouths for stating electromagnetism support valve are connected with radiator, and the T mouths of magnetic valve support valve take back hydraulic oil container；The import of the radiator
End is provided with pressure measuring tie-in.
Further, it is provided with thermometer in the hydraulic oil container.
The beneficial effects of the utility model are：It is of the present utility model simple in construction, operation facility, it is ensured that difference pressure
The test requirements document of power pulse, the pulse checking to fork truck radiator is rapidly completed, manpower is saved, reduces experimentation cost.
Brief description of the drawings
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings, wherein：
Fig. 1 is structural representation of the present utility model；
Wherein：1- hydraulic oil containers, 2- cleaners, 3- gear pumps, 4- variable-frequency motors, 5- electromagnetism support valve, 6- thermometers, 7-
Radiator.
Embodiment
A kind of fork truck radiator impulse test device shown in 1 referring to the drawings, including radiator 7, hydraulic oil container 1, frequency conversion
Motor 4, gear pump 3 and electromagnetism support valve 5.Electromagnetism support valve 5 be existing product, its collection overflow valve, check valve, choke valve,
The valve of electromagnet cut off valve four, has three P mouths, A mouths, T mouths hydraulic fluid ports.
Cleaner 2 and thermometer 6 are provided with the hydraulic oil container 1, the cleaner 2 passes through fuel sucking pipe and gear pump 3
Import connects, and the gear pump 3 electrically connects with variable-frequency motor 4, and the outlet of gear pump 3 supports the P of valve 5 by flowline with electromagnetism
Mouth connection, the A mouths of the electromagnetism support valve 5 are connected with radiator 7, and the T mouths of magnetic valve support valve 5 take back hydraulic oil container 1；It is described
The entrance point of radiator 7 is provided with pressure measuring tie-in, to measure the pulse during experiment（To embody in figure, with reference to existing
There is design）.
Operation principle of the present utility model is as follows：Adjust the pressure of electromagnetism support valve 5, flow adjustment knob is suitable location
Afterwards, start variable-frequency motor 4 and drive gear pump 3, gear pump 3 is delivered to electromagnetism support valve from after draw oil in hydraulic oil container 1
5, so it is oily to the delivery hydraulic pressure of radiator 7.
During experiment, the pulse of observation compression fittings detection, hydraulic pressure is controlled by the rotating speed for adjusting variable-frequency motor 4
The output flow of oil, pulse and flow are adjusted by the pressure of electromagnetism support valve 5, flow adjustment knob, control electromagnetism
The commutation of valve 5 is supported, different pulses is obtained, so as to meet the pulsating fatigue test requirements document to fork truck radiator.
It is described above, the only preferable embodiment of the utility model, but scope of protection of the utility model is not limited to
In this, any one skilled in the art is in the technical scope that the utility model discloses, the change that can readily occur in
Change or replace, should all cover within the scope of protection of the utility model.Therefore scope of protection of the utility model is with claim
The protection domain of book is defined.
