Technical Field
The utility model belongs to the technical field of hydraulic measurement, and relates to a long-time oil drainage quantity testing device.
Background
The leakage of the product is generally tested by adopting a hand pump or a test bed, the method is generally used for measuring the leakage value in a short time, once the leakage is tested for a long time (more than 24 h), the hand pump needs to continuously supplement pressure, and the time and the labor are wasted; the test bench is adopted for leakage test, because the leakage quantity value of a product is very small, oil liquid in the test bench cannot be sufficiently cooled, the service life of the test bench can be greatly shortened in long-term leakage test, even the test pipeline can be broken, the test can be stopped midway, and the test of long-term leakage cannot be completed.
SUMMERY OF THE UTILITY MODEL
The purpose of the utility model is: a long-time oil drainage test device is provided. The utility model greatly reduces the labor cost of the test, reduces the safety risk of the test bed and the test, and ensures the safety of the long-time test.
The technical scheme of the utility model is as follows: a long-time oil drainage testing device comprises a test oil source, a stop valve, an energy accumulator and a pressure gauge which are connected in series through pipelines in sequence; the pressure gauge is used for measuring the pressure of the energy accumulator.
In the long-time oil drainage testing device, the energy accumulator is connected with the oil inlet pipe opening at one side of the tested product through a pipeline, and the other oil ports of the tested product are respectively connected with the measuring cup.
In the long-time oil drainage testing device, the pressure of the energy accumulator is 1-2 MPa higher than the rated test pressure.
In the long-time oil drainage amount testing device, the pressure of the energy accumulator is not lower than the rated test pressure within the preset observation time.
In the long-time oil drainage testing device, the stop valve is closed after the energy accumulator is charged by the test oil source.
In the long-time oil drainage testing device, the stop valve is a mechanical stop valve.
The utility model has the advantages that: according to the utility model, the accumulator replaces a test oil source to supply pressure to the tested product for a long time, so that the risk of pump burning when the test oil source oil pump works for a long time is avoided, and the test safety is improved. Meanwhile, the pressure of the energy accumulator in the observation time (generally 8h) is not lower than the rated test pressure, so that a tester does not need to frequently maintain the pressure through manual pressure, the labor intensity of the test is greatly reduced, and the test efficiency is improved.
In conclusion, the utility model greatly reduces the labor cost of the test, reduces the safety risk of the test bed and the test, and ensures the safety of the long-time test.

Detailed Description
The utility model is further illustrated by the following figures and examples, which are not to be construed as limiting the utility model.
Example 1. The utility model provides a long-time draining volume testing arrangement, constitutes as shown in figure 1, mainly includes experimental oil source 1, pipeline 2, stop valve 3, manometer 4 and energy storage ware 5, connects experimental oil source 1, stop valve 3, manometer 4, energy storage ware 5 and tested product 6 in series together through pipeline 2, and stop valve 3 is between experimental oil source 1 and energy storage ware 5, and manometer 4 is between energy storage ware 5 and tested product 6. During testing, the pipeline 2 is connected with an oil inlet pipe orifice at one side of a tested product 6, and other oil ports of the tested product are respectively connected with a measuring cup 7; during testing, the energy accumulator 2 is charged through the test oil source 1, the pressure of the energy accumulator 2 is monitored through the pressure gauge 4, the pressure of the energy accumulator 2 is higher than the rated test pressure by 1-2 MPa, the volume of the energy accumulator 2 is reduced to the rated test pressure according to the pressure of the energy accumulator 2 for 8 hours, and the pressure of the test oil source 1 is closed after the energy accumulator 2 is fully charged. When testing for a long time, once the pressure displayed by the pressure gauge 4 is found to be lower than the required test pressure, the test oil source 1 is started to be raised to the required pressure, the stop valve 3 is opened to charge the energy accumulator 5, and when the pressure of the energy accumulator 2 is higher than the rated test pressure (1-2) MPa, the stop valve 3 is closed, the pressure of the test oil source 1 is reduced, and the test oil source 1 is closed. The process is circulated until the test is finished. The structure effectively tests the tiny leakage value between long-time systems, and avoids the faults caused by the fact that a test oil source works for a long time, particularly a test oil source pump station cannot be cooled sufficiently under the tiny leakage condition.
Example 2. A long-time oil drainage testing device is shown in figure 1 and comprises a test oil source 1, a stop valve 3, an energy accumulator 5 and a pressure gauge 4 which are connected in series through a pipeline 2 in sequence; the pressure gauge 4 is used for measuring the pressure of the accumulator 5.
The energy accumulator 5 is connected with an oil inlet pipe orifice at one side of the tested product 6 through the pipeline 2, and other oil ports of the tested product 6 are respectively connected with the measuring cup 7.
