Problems solved by technology

If the flow rate, spray angle, and spray cone angle that meet the standard requirements cannot be achieved, the engine bearing will work abnormally, or even be damaged by overheating
[0003] At present, the engine manufacturer does not provide any equipment for testing the flow rate of the lubricating oil nozzle in the bearing cavity, so it is difficult to effectively control the lubricating oil flow output by the nozzle

Embodiment 1

[0029] like Figure 1~2 A test device for lubricating oil nozzles of engine bearings is shown, including a first filter 17, an oil supply pump 6, a temperature sensor 11, a second filter 18, a supply pressure control valve 9, and a flow sensor connected in sequence by pipelines 13. Collection pool 23, pneumatic oil pump 24, oil barrel 25, supply control valve 26, third filter 19, oil return pump 7, fourth filter 20, oil tank 21, outlet of flow sensor 13 and inlet of collection pool 21 There is a nozzle 28 under test indirectly between the ends.

[0030] The oil tank 21 is used to hold and heat lubricating oil; electric heater 4, first filter 17, oil supply pump 6, temperature sensor 11, second filter 18, supply pressure control valve 9, flow sensor 13, pressure sensor 15 , a temperature controller 12, a flow indicator 14, a pressure indicator 16, a sensitive valve 8, a trim valve 10, a third filter 19, an oil return pump 7, and a fourth filter 20 together constitute a lubrica...

Embodiment 2

[0041] like image 3 Shown is the second embodiment of the test device of the engine bearing lubricating oil nozzle of the present invention. The difference between the second embodiment and the first embodiment is that a lubricating oil sampling and analysis unit 27 is added in the second embodiment. The lubricating oil tested by the tested nozzle 28 is sampled and analyzed to prove whether the used lubricating oil can be reused. Since the nozzle 28 under test has lubricating oil used for installation, these lubricating oils contain a lot of impurities and the viscosity is reduced. The lubricating oil used for installing is mixed with the lubricating oil used for testing. This mixed lubricating oil will affect the measured Nozzle 28 test results, therefore, sampling and assaying this miscellaneous lubricating oil can reduce the positiveness of the miscellaneous lubricating oil to the test. Laboratory analysis is to detect the amount of impurities and viscosity of lubricating...

Abstract

The invention discloses a testing device of an engine bearing oil nozzle. The testing device of the engine bearing oil nozzle comprises a first filter, a fuel feed pump, a temperature sensor, a second filter, a supply pressure control valve, a flow sensor, a collecting pool, a pneumatic oil pump, an oil drum, a replenishment control valve, a third filter, an oil scavenger pump, a fourth filter and an oil tank through pipelines in a successive connection mode, wherein a measured nozzle is arranged between an outlet end of the flow sensor and an inlet end of the collecting pool. The first filter is arranged in the oil tank, and an electric heater is arranged in the oil tank. A heating cycle oil line is arranged between an outlet end of the fuel feed pump and an inlet end of the oil scavenger pump. The temperature sensor is connected to a temperature controller through data lines. The temperature controller controls a heater. A balancing bypass is arranged between an outlet end of the temperature sensor and an inlet end of the third filter. A balancing valve is arranged on the balancing bypass. The flow sensor is in external connection with a flow displayer. By the adoption of the testing device of the engine bearing oil nozzle, an actual fuel feeding condition is achieved, simultaneously, the nozzle can be tested in real time, and normal work of a bearing is guaranteed.

Description

technical field [0001] The invention relates to a testing device for engine components, in particular to a testing device for lubricating oil nozzles of engine bearings. Background technique [0002] The bearing lubricating oil nozzle in the engine (or bearing lubricating oil nozzle) is one of the components of the lubrication system. The lubricating system mainly includes nozzles, throttles, circulation oil passages, and sealing rings. The lubricating oil is guided through the oil passage and then passed The nozzle sprays onto the engine bearings, thereby lubricating and cooling the engine bearings. In order to lubricate and cool engine bearings well, the lubricating oil nozzle must have a standard flow rate, a precise spray angle and a suitable spray cone angle. If the flow rate, spray angle, and spray cone angle that meet the standard requirements cannot be achieved, the engine bearing will work abnormally, or even be damaged by overheating. [0003] At present, the eng...
