[0025] The following will be combined Figure 1-7 The present invention is described in detail. The exemplary embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention. The oil pump in this solution is a test piece.
[0026] An electronic oil pump test device includes a base plate 5 and an oil tank assembly 1, an inlet assembly 2, an outlet assembly 3, and an oil pump installation assembly 4, all of which are installed on the base plate. The oil tank assembly is used to store test oil and filter oil. The inlet assembly controls the oil to enter the oil pump test by opening or closing the inlet switch valve. The outlet assembly controls the oil from the oil pump to enter the oil tank assembly by opening or closing the precision control valve, and provides different pressure loads for the oil pump by adjusting the valve body opening. The oil pump installation assembly is used for oil pump installation and oil pump output pressure monitoring. The oil tank assembly, the inlet assembly, the outlet assembly, and the oil pump installation assembly are all installed on the base plate by screws to form a complete oil pump test device. The base plate is made of aluminum alloy, and screw holes of different specifications are designed according to the assembly requirements of related components. At the same time, a handle 5.2 is provided on the top of the base plate for the hand-held position when the oil pump test device is carried and moved, saving manpower. Four evenly distributed foot pads 5.3 are installed at the bottom of the base plate by screws. The material of the foot pad is a temperature-resistant rubber material of -40℃ to 150℃, which can effectively play a vibration reduction role.
[0027] The fuel tank assembly includes a fuel tank 1.1 and a fuel tank cover plate 1.5 made of transparent material. The fuel tank is fixed on the bottom plate and an oil filter mounting plate 1.2 and an oil filter 1.3 are sequentially installed in the fuel tank from bottom to top. By assembling the oil filter and the oil filter mounting plate, the filtering function of the automobile oil circulation system can be simulated to filter the oil. Impurities and debris in the entire test device can be filtered to avoid additional damage to the test sample - the oil pump. A fuel tank sealing ring 1.4 is provided in the fuel tank cover plate and is sealed with the fuel tank, which can play a sealing role. At the same time, an oil inlet is provided on the fuel tank cover plate. The test medium - oil, is stored in the fuel tank. The transparent material fuel tank cover plate is convenient for testers to observe the internal condition of the fuel tank.
[0028] The inlet assembly includes an oil tank interface 2.3, an inlet switch valve 2.1, a pipeline interface 2.4, a first metal hose 2.5 and an oil pump bracket interface 2.6 which are arranged in sequence along the oil flow direction. The inlet switch valve is used to control the amount of oil entering the oil pump and is fixed to the bottom plate through a fixing block 2.2. The left side of the inlet switch valve is connected to the oil tank interface 2.3 by a thread. The other side of the oil tank interface away from the inlet switch valve is installed with the oil tank by several screws. The right side of the inlet switch valve is connected to the pipeline interface by a thread. The first metal hose is connected to the pipeline interface and the oil pump bracket. A sealing gasket 2.8 is provided between them and clamps 2.7 are provided at the connections between the pipeline interface and the oil pump bracket on both sides of the first metal hose. The other side of the oil pump bracket interface away from the first metal hose is installed with the oil pump mounting assembly by several screws. At the same time, the other side of the oil tank interface and the other side of the oil pump bracket interface are equipped with a first sealing ring 2.9. The sealing gasket and the first sealing ring are used to seal. The threaded connection parts of the inlet switch valve on both sides and the oil tank interface and the pipeline interface are wrapped with waterproof sealing tape to ensure that the seal of the connection position is leak-proof.
[0029] The outlet assembly includes a precision control valve 3.1, an outlet fixing block 3.2 and a second metal hose 3.3. By rotating the disc above the precision control valve and adjusting the test valve opening, the outlet pressure can be provided for the oil pump, and the test conditions of different loads of the oil pump can be tested. A sealing gasket 2.8 is installed between the precision control valve and the oil tank, and is fixed to the oil tank by screws to achieve a sealing function; the outlet fixing block is used for connecting the precision control valve and the oil pump bracket interface 2.6, and the two sides are respectively equipped with a sealing gasket 2.8 and a first sealing ring 2.9, which respectively realize the sealing function with the precision control valve and the oil pump bracket interface; the two ends of the second metal hose are respectively connected to the oil pump bracket interface, and a sealing gasket 2.8 is installed therebetween, and finally fixed and installed by a clamp 2.7 to achieve the sealing of the entire pipeline, and the oil pump bracket interfaces 2.6 at both ends are respectively assembled on the outlet fixing block and the oil pump mounting assembly, and are assembled with a sealing ring 2.9 at the same time, and finally the overall sealing from the oil tank 1.1 to the oil pump mounting assembly is achieved.
[0030] The oil pump assembly includes an oil pump bracket 4.1 that matches the oil pump 4.4 assembly, and also includes a pressure gauge interface 4.2 and a pressure gauge 4.3. The inlet and outlet of the oil pump bracket are respectively connected to the first metal hose and the second metal hose through the oil pump bracket interface 2.6. The oil pump installation assembly takes the oil pump bracket as the core, and designs a special oil pump bracket for the assembly requirements of each oil pump. However, the assembly design of the oil pump bracket interface at its inlet and outlet is universal. Different oil pump products can share the oil pump test assembly by only involving the production of a special oil pump bracket, which greatly reduces the production cost and saves the production cycle. The pressure gauge interface is sealed and assembled on the oil pump bracket through the pressure gauge sealing ring 4.5 to achieve the sealing function. The pressure gauge is assembled into the pressure gauge interface through a threaded connection and a sealing tape is wrapped around the thread of the pressure gauge to achieve the sealing of the pressure gauge.
[0031] During the test, the opening of the precision control valve is adjusted through the numerical feedback on the pressure gauge, so as to manually intervene in the pressure regulation of the oil circuit test assembly, and ultimately meet the different working conditions of the oil pump test requirements.
[0032] The oil seal ring, sealing gasket, first seal ring and pressure gauge seal ring in this solution are all made of rubber material that is temperature-resistant at -40°C to 150°C and resistant to engine oil, meeting vehicle environmental requirements.
[0033] In a specific embodiment, the entire oil pump test device has an outer size of length*width*height=656*514*307mm, which is small, light and flexible. The entire device can be placed in high-temperature or low-temperature equipment according to test requirements to realize tests under different working conditions.
[0034] During the implementation process, Figure 8As shown, the test personnel control the rotation of the test piece - oil pump 4.4 through the control system, and the oil in the test bench flows in the direction of the dotted arrow. The pressure gauge 4.3 displays the oil flow pressure in real time. By adjusting the opening of the precision control valve 3.1, the pressure of the oil flowing out of the oil pump can be increased or decreased to meet the test of different working conditions. When the oil enters the internal pipeline of the oil tank 1.1, it enters the oil filter 1.3, and finally flows out of the oil tank and flows into the inlet switch valve body 2.1. At this time, the oil has been filtered, which can prevent impurities from flowing into the oil pump 4.4 and ensure that the rotating parts in the oil pump are not worn. This is a simulation of on-vehicle application. The opening of the inlet switch valve 2.1 can also be adjusted to increase or decrease the pressure of the oil entering the oil pump to meet the test of different working conditions.
[0035] In the current project development, large-scale special oil pump test equipment is usually used for product debugging and testing. Because the equipment is expensive (usually millions of dollars), it leads to the disadvantages of limited number of test samples, long test cycle, high test cost, low flexibility, etc. Now, a set of cost data comparison is made between the electronic oil pump test bench sold in the market and this solution, as shown in the following table:
