Abstract
The utility model discloses a hydraulic component testing device which comprises a testing support and a pressure supplying system arranged on the testing support. The pressure supplying system comprises a hydraulic pump, a drive device in transmission connection with the hydraulic pump, a hydraulic oil tank and a multi-way valve. An oil outlet of the hydraulic oil tank is connected with an oil inlet of the hydraulic pump. An oil inlet of the hydraulic oil tank is connected with an oil return opening of the multi-way valve. An oil inlet of the multi-way valve is connected with an oil outlet of the hydraulic pump. The multi-way valve further comprises two oil outlet ports for being in series connection with a hydraulic component to be tested. Before installation of a hydraulic system of a harvester, the device is used for testing pressure bearing capacity of corresponding components so as to ensure reliability of all the hydraulic components in a finished automobile.
Description
Technical field
The utility model relates to a kind of hydraulic unit testing apparatus.
Background technique
The hydraulic system of grain harvesting machine contains the many kinds of liquid pressure part, as control system, gear pump, valve, hydraulic pipe line and hydraulic joint etc., the bearing capacity of each hydraulic unit has a direct impact the performance of hydraulic system, and bearing capacity is low, and oil leakage phenomenon easily occurs.Although independent hydraulic pipe line had carried out pressure test before producer dispatches from the factory, but the bearing capacity of other hydraulic unit is unclear, especially when whole hydraulic system on cropper the assembling complete after, if there is problematic hydraulic unit, be not easy the place of pinpointing the problems in the equipment debugging process, stayed potential safety hazard for the complete machine operation; Even pinpoint the problems, also to dismantle whole hydraulic system, increased undoubtedly commissioning staff's the amount of labour and debug time.
The model utility content
The purpose of this utility model be to provide a kind of the installation before just can grasp the testing apparatus of each hydraulic unit bearing capacity of hydraulic system.
The utility model adopts following technological scheme: a kind of hydraulic unit testing apparatus, comprise test bracket and be arranged on test bracket for pressing system, the described pressing system that supplies comprises oil hydraulic pump and the drive unit that is connected with hydraulic pump driving, also comprise hydraulic oil container and multi-way valve, the oil outlet of described hydraulic oil container is connected with the filler opening of oil hydraulic pump, filler opening is connected with the return opening of multi-way valve, the filler opening of described multi-way valve is connected with the oil outlet of oil hydraulic pump, and multi-way valve also has the oil out port that is used for supplying hydraulic unit serial connection to be measured of two.
Described oil hydraulic pump is for detachably being assemblied in the gear pump on test bracket, and described drive unit is motor.
Be serially connected with pressure maintaining valve between described oil hydraulic pump and multi-way valve, be serially connected with pressure gauge between pressure maintaining valve and multi-way valve.
Adopt the hydraulic unit testing apparatus of said structure, owing to having contained the parts such as oil hydraulic pump, hydraulic oil container, multi-way valve for pressing system, be connected to form a complete chain tape between them, with being connected with two oil outlets of multi-way valve respectively into and out of hydraulic fluid port of hydraulic unit to be measured, drive unit provides power for oil hydraulic pump, provide needed pressure by the power of regulating drive unit for the confession pressing system, realize that the bearing pressure of hydraulic unit to be measured detects.Before the hydraulic system installation of cropper, by the bearing capacity of the corresponding hydraulic unit of this device to test, guarantee the reliability of each hydraulic unit in car load.
Description of drawings
Fig. 1 is a kind of embodiment's of the present utility model structural representation.
Embodiment
The embodiment of the utility model hydraulic unit testing apparatus: as shown in Figure 1, comprise test bracket 5, be equipped with on test bracket 5 for pressing system, comprise oil hydraulic pump 3, drive unit 2, hydraulic oil container 1, multi-way valve 7 and pressure maintaining valve 4 for pressing system, in the present embodiment, oil hydraulic pump 3 adopts gear pump, and drive unit 2 adopts motor.Oil hydraulic pump 3 detachably is assemblied on test bracket 5, the oil outlet of hydraulic oil container 1 is connected with the filler opening of oil hydraulic pump 3, the return opening of filler opening multi-way valve 7 connects, the filler opening of pressure maintaining valve 4 is connected with the oil outlet of oil hydraulic pump 3, oil outlet is connected with the filler opening of multi-way valve 7, multi-way valve 7 also has two oil out port simultaneously, is connected with respectively test on two oil out port with managing 6.
Connection between each parts of the present embodiment all realizes by hydraulic pipe line and hydraulic joint, in addition, be equipped with pressure gauge on the pipeline between oil hydraulic pump and multi-way valve, for detection of the pressure in oil hydraulic pump downstream, can see more intuitively the pressure size of hydraulic circuit.
During application, for inhomogeneous hydraulic unit to be measured, if during the oil hydraulic cylinder of test cropper hydraulic system, with two tests with pipe 6 respectively with being connected into and out of hydraulic fluid port of hydraulic unit to be measured, oil hydraulic pump 3 will convert high pressure oil to by the hydraulic oil that hydraulic oil container 1 provides, high pressure oil enters hydraulic unit to be measured through the in-line of multi-way valve 7, then passes through in the vent line hydraulic return fuel tank 1 of multi-way valve 7 again; If during the oil hydraulic pump of test cropper hydraulic system, the application's oil hydraulic pump is replaced, then two tests are got final product with other pipe fittings connections of pipe 6 use.
In other embodiments, oil hydraulic pump also can adopt vane pump or plunger pump, and drive unit is selected the equipment corresponding with oil hydraulic pump.
