Description
Technical field
The utility model relates to oil pump Performance Detection technical field, is specifically a kind of oil pump performance testing device.
Background technique
The effect of oil pump provides reliable lubrication to the key position such as motor car engine, gearbox.Oil pump is generally made up of housing, internal rotor, external rotor and pump cover etc.Oil pump dispatch from the factory last as to carry out the platform experiment of Performance Detection, to ensure the qualified of product of dispatching from the factory.General when carrying out oil pump testing property, test out oil pump under the different oil temperatures of regulation, the curve of its fuel pump outlet pressure versus flow relation, thus compare from the curve of fuel pump outlet pressure versus flow relation under the different oil temperatures of regulation, thus show whether machine oil pump performance reaches the Eligibility requirements of regulation.Described different oil temperatures are generally in 40 DEG C ~ 140 DEG C, and optional several oil temperature point, as 40 DEG C, 50 DEG C, 80 DEG C, 90 DEG C, 120 DEG C, 140 DEG C etc., tests fuel pump outlet pressure versus flow relation under this different temperatures.And the oil pump performance testing device of prior art is when carrying out its testing property, first successively by machine oil heating to different temperature spotss, then utilize flow transducer and pressure transducer to measure the relation of fuel pump outlet pressure versus flow.Due to when machine oil heating or cooling, the required time is longer, thus makes oil pump testing property consuming time longer, and testing efficiency is lower.And for producing the producer of oil pump in enormous quantities, its slowly detection speed can not meet the demand of production in enormous quantities, affect the economic benefit of enterprise.
Model utility content
The technical problems to be solved in the utility model is, overcome the defect of above prior art, the variation relation of a kind of oil pump of simulation test at the same temperature fuel pump outlet pressure versus flow when different temperatures is provided, and the oil pump performance testing device that the test time is short, testing efficiency is high.
Technical solution of the present utility model is, there is provided a kind of oil pump performance testing device with following structure: it comprises worktable, oil groove, described worktable is connected with oil pump to be detected, it also comprises control module and data disaply moudle, described oil groove is communicated with the inlet port of oil pump to be detected, the oil outlet of described oil pump to be detected is communicated with oil exit pipe, the outlet end of described oil exit pipe is communicated with main oil pipe and return tube, and described main oil pipe is all communicated with oil groove with the outlet of return tube; Described oil exit pipe is connected with flow transducer, the first pressure transducer and the first pressure regulator valve in turn along oil extraction direction, described main oil pipe is connected with the second pressure transducer, return tube is connected with the second pressure regulator valve; Described data disaply moudle, flow transducer, the first pressure transducer, the second pressure transducer, the first pressure regulator valve are all connected with control module with the second pressure regulator valve.
The first described pressure regulator valve and the second pressure regulator valve are relief valve.
Described control module is PLC.
After adopting above structure, the utility model oil pump performance testing device compared with prior art, have the following advantages: this oil pump performance testing device is when testing, oil pump to be measured is installed on the table and the inlet port of oil pump is communicated with oil exit pipe with oil groove respectively with oil outlet, then oil temperature is heated to setting value, as 90 DEG C, make oil pump work to be measured, the flux signal that machine oil discharged by oil exit pipe inner engine oil pump is passed to control module by flow transducer, and is shown by data disaply moudle, keep the flow of oil exit pipe inner engine oil constant, control module controls the first pressure regulator valve and the second pressure regulator valve is opened, then control module controls the change of the first pressure regulator valve aperture, thus measured with the first pressure regulator valve aperture change and the oil pressure (being also fuel pump outlet pressure) of the oil exit pipe of change by the first pressure transducer again, carry out curve plotting by the data of the fuel pump outlet pressure versus flow recorded, then to compare the requirement seen and whether reach regulation with the relation curve of fuel pump outlet pressure versus flow at this temperature (90 DEG C) of regulation, when measuring other temperature spotss beyond this temperature 90 DEG C, during as 40 DEG C, control module controls the continuous change of the first pressure regulator valve and the second pressure regulator valve aperture, the pressure range specified when making the pressure between the first pressure regulator valve and the second pressure regulator valve reach this temperature (40 DEG C), the force value within the scope of this is measured again by the second pressure transducer, the relation curve of fuel pump outlet pressure versus flow when can draw out this temperature (40 DEG C), and then to compare the requirement seen and whether reach regulation with the relation curve of fuel pump outlet pressure versus flow at this temperature (40 DEG C) of regulation, by that analogy, under can different temperatures being drawn, the relation curve of fuel pump outlet pressure versus flow, thus compare with the relation curve of fuel pump outlet pressure versus flow that specifies under this different temperatures again, so just can show whether machine oil pump performance reaches the Eligibility requirements of regulation.Therefore, this oil pump performance testing device can at the same temperature, and the variation relation of simulation test engine oil pump fuel pump outlet pressure versus flow at different temperatures, the test time is short, testing efficiency is high.
