Abstract
The utility model discloses an oil pump pressure-limiting valve starting pressure testboard comprising a working platform (1), a fixture (2) arranged on the working platform (1) and used for clamping an oil pump to be tested, a sensor and a pressing plate device (3) arranged above the fixture, wherein the fixture (2) is provided with a gas flowmeter (4) for detecting the flow of gases at an outlet of the oil pump. The oil pump pressure-limiting valve starting pressure testboard has good test accuracy.
Description
Technical field
The utility model relates to test board, specifically is a kind of lubricating oil pump pressure limiting valve opening pressure test board.
Background technology
Each lubricating pump of automobile must carry out the test of the opening pressure of pressure limiting valve before dispatching from the factory, current test has had the oil survey to change the gas survey into, high pressure gas flows out from the lubricating oil pump outlet by pressure limiting valve from the inner chamber of lubricating oil pump, in the inner chamber of lubricating oil pump, sensor is set during test, comes the detected air pressure pressure drop by sensor.Though it is easy to clean that above gas is surveyed, the efficient height, but still have the following disadvantages: because sensor reads pressure time and is spaced apart 0.2s, read a force value a when being 0.2s, 0.4s the time read another force value b, force value after force value a and force value b subtract each other is pressure drop during greater than a certain setting value, and test board judges that then pressure limiting valve opens.But because pressure limiting valve is to-and-fro movement when opening, may be the same in the position between 0.2s and the 0.4s, just do not produce pressure drop yet,, so just cause the test board test accuracy poor even if pressure limiting valve is that opening can not become unlatching by erroneous judgement yet like this.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of test accuracy good lubricating oil pump pressure limiting valve opening pressure test board.
The technical solution of the utility model is, a kind of lubricating oil pump pressure limiting valve opening pressure test board with following structure is provided, comprise worktable, be arranged on anchor clamps, the sensor of the tested lubricating oil pump of clamping on the worktable and be located at the presser device of anchor clamps tops, described anchor clamps are provided with the gas meter of machines oil pump exit gas flow.
The utility model compared with prior art, have the following advantages: because described anchor clamps are provided with the gas meter of machines oil pump exit gas flow, when test, judge by gas meter whether pressure limiting valve is opened, promptly judge by the variation of flow, avoiding sensor is that opening also can be become the situation of not opening by erroneous judgement for pressure limiting valve, the assurance sensor can accurately be responded to pressure drop, makes test board accuracy of the present utility model good
As improvement, it also comprises the ratio adjusting valve that is located on the anchor clamps the utility model, described ratio adjusting valve is located between gas meter and the tested machine oil delivery side of pump, can regulate the outlet air pressure of tested lubricating oil pump, guarantee the scope of application of gas meter, thereby make test board can be fit to the pressure limiting valve opening pressure test of the lubricating oil pump of all size model, applicability is wide.
Description of drawings
Accompanying drawing 1 is the structural representation of lubricating oil pump pressure limiting valve opening pressure test board of the present utility model.
Accompanying drawing 2 is the anchor clamps schematic top plan view of lubricating oil pump pressure limiting valve opening pressure test board of the present utility model.
As shown in the figure: 1, worktable, 2, anchor clamps, 3, presser device, 4, gas meter, 5, ratio adjusting valve.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 and Figure 2, lubricating oil pump pressure limiting valve opening pressure test board of the present utility model, lubricating oil pump pressure limiting valve opening pressure test board comprises worktable 1, is arranged on anchor clamps 2, the sensor of the tested lubricating oil pump of clamping on the worktable 1 and is located at the presser device 3 of anchor clamps tops.Described sensor is positioned on the anchor clamps 2, after tested lubricating oil pump installs, sensor just is positioned at the inner chamber of lubricating oil pump, described anchor clamps 2 are provided with two register pins, its upper surface also is provided with sealing gasket, described presser device 3 is that conventional pressing plate and depression bar formed, and its expanding-contracting action is driven by cylinder, and described anchor clamps 2 are provided with the gas meter 4 of machines oil pump exit gas flow.
Described gas meter 4 is positioned at the exit of tested lubricating oil pump.
Lubricating oil pump pressure limiting valve opening pressure test board of the present utility model, it also comprises the ratio adjusting valve 5 that is located on the anchor clamps 2, described ratio adjusting valve 5 is located between gas meter 4 and the tested machine oil delivery side of pump.
Above gas meter 4 all is connected with the PLC programmed control mainboard of test board with ratio adjusting valve 5, and concrete connected mode and principle of work are conventional prior art, so do not give unnecessary details at this.Certainly gas meter 4 and ratio adjusting valve 5 can also be directly arranged on the worktable, are communicated with by tracheae between two.
Claims (3)
