The invention provides an internal combustion engine oil pump test bed, and relates to an oil pump test bed. The test bed is used for testing the comprehensive performance of gear pumps and rotor pumps of internal combustion engines and other volumetric oil pumps. The internal combustion engine oil pump test bed comprises a drive motor, a torque-rotating speed measuring instrument, a thermometer, a pressure gauge, a regulating valve, a change valve, a gear flowmeter, an oil tank, a heating thermostat, an overflow valve, a vacuum pressure gauge, and an oil suction filter net; and the internal combustion engine oil pump test bed is characterized by also comprising a transparent flowmeter, wherein the transparent flowmeter is connected in series to an oil outlet pipe behind the pressure gauge and before the regulating valve and the overflow valve. The internal combustion engine oil pump test bed has the advantages that: whether an oil pump to be tested leaks air can be intuitively observed, and oil pumps to be tested of which the flow rates do not meet the JB/T8413 standard requirement obviously can be directly found through reading without complicated calculation.

Description

The engine oil pump of internal combustion engine test stand
Technical field
The present invention relates to a kind of lubricant pump test-bed, this test stand is in order to the assembly performance of test internal-combustion engine with gear pump and rotor pump and other positive displacement oil pump.
Background technique
The engine oil pump of internal combustion engine product is before dispatching from the factory, and product quality standard department of manufactory must completely examine quality of product, performance, whether meets the company standard of JB/T 8413 and relevant product to identify product.NBS JB/T 8886-1999 stipulated internal-combustion engine with the assembly performance testing apparatus of gear pump and rotor pump and other positive displacement oil pump by drive motor, turn round square – tachometer of measuring, thermometer, pressure gauge, modulating valve, selector valve, gear meter, fuel tank, heating constant-temperature equipment, relief valve, pressure vacuum gauge and oil suction filter screen and constitute.Its working principle is: tested oil pump is installed on the test stand, rotates under the drive of drive motor, reads rotating speed by moment of torsion-tachometer of measuring; Tested oil pump produces negative pressure because the increase of sealed volume forms parital vacuum in rotary course, fluid enters in the tested oil pump by the oil suction filter screen and realizes oil suction, and pressure vacuum gauge is read input pressure; Read temperature and the pressure that pumps hydraulic fluid port by thermometer and pressure gauge; Fuel-displaced size of regulating flow by modulating valve through selector valve connection gear flowmeter, can calculate and judge from the reading of gear meter whether oil pump capacity is qualified; Relief valve plays the overflow pressure stabilization function; The constant temperature of oil is guaranteed by heating constant-temperature equipment in the fuel tank, and thermometer is used to measure the temperature of oil.Put into practice through long-term the detection, we find that there is following defective in the test stand of JB/T 8886-1999 regulation: 1, because flowmeter adopts gear meter, though test traffic is very accurate, but can't directly read the result from flowmeter, must be through complicated calculating, therefore use trouble, and more time-consuming.2, through the test stand of JB/T 8886-1999 regulation examine the quality of the production, performance shows that qualified product still might be the waste product pump of gas leakage.
Summary of the invention
The objective of the invention is to overcome the prior art deficiency, provide a kind of tested oil pump that can visually see whether to leak gas, do not need just can directly read the engine oil pump of internal combustion engine test stand that flow does not obviously meet the tested oil pump of JB/T 8413 regulations requirement through complicated calculations.
Technical solution of the present invention is: the engine oil pump of internal combustion engine test stand comprises drive motor, Niu Ju – tachometer of measuring, thermometer, pressure gauge, modulating valve, selector valve, gear meter, fuel tank, heating constant-temperature equipment, relief valve, pressure vacuum gauge and oil suction filter screen; The drive motor tested oil pump that is in transmission connection, moment of torsion-tachometer of measuring is connected between drive motor and the tested oil pump; The filler opening of tested oil pump is connected with the oil suction filter screen by oil inlet pipe, and the oil suction filter screen is immersed in the fluid of fuel tank, and pressure vacuum gauge is installed on the oil inlet pipe; The oil outlet of tested oil pump is connected with relief valve with modulating valve respectively by oil outlet tube, pressure gauge and thermometer are installed on the oil outlet tube, the flow-off of relief valve is connected with fuel tank, modulating valve connects selector valve, gear meter and fuel tank successively by oil pipe, and heating constant-temperature equipment and fuel tank thermometer are arranged in the fuel tank; The diameter of oil inlet pipe and oil outlet tube is more than or equal to the twice of tested oil pump into and out of the hydraulic fluid port diameter; It is characterized in that: the present invention also comprises a transparent flowmeter, and transparent flowmeter is connected on the pressure gauge rear side, on the oil outlet tube of modulating valve and relief valve front side.
Described transparent flowmeter comprises a transparent straight pipe that has scale, and the two ends envelope of transparent straight pipe has end cap, is fixed with a guide rod between two end cap, and buoy is enclosed within on the guide rod, and can run through being connected with oil outlet tube on the two end cap respectively along the upper and lower slip of guide rod.
Described buoy is a stainless steel, and it is truncated cone, and the less taper platform bottom surface of area is arranged on oil inlet end one side of transparent flowmeter.
Described transparent flowmeter adopts the glass flow rate meter that is used for the test water flow in the chemical field.
Advantage of the present invention is: 1, owing to inserted the glass flow rate meter on the oil outlet tube between modulating valve and the tested oil pump, by pumping oil whether bubble is arranged in the sight glass flowmeter, can judge whether tested oil pump leaks gas; 2, the variation of the position of the buoy by the sight glass flowmeter, can judge intuitively whether tested oil pump capacity conforms with designing requirement, although the flow that the glass flow rate meter shows is accurate like that by the flow that calculates not as good as gear meter, but by the sight glass meter readings, can reject most tested oil pump that JB/T 8413 regulations require that obviously do not meet, the tested oil pump that has query is carried out accurate Calculation by gear meter again, see whether meet JB/T 8413 regulation requirements, can save the substantive test time like this.
