Problems solved by technology

[0003] Due to the quality of diesel oil, the internal one-way valve of the hand oil pump that pumps oil at the dirty oil end is often stuck and does not work, which directly leads to the failure of the hand oil pump function, especially when the engine needs to be exhausted after the engine stops. The air in the tank cannot be exhausted, and the engine cannot be started, causing great trouble to the user

Embodiment 1

[0020] Embodiment one: if figure 1 and figure 2 As shown, an electric oil pump 100 without a bypass oil circuit includes a pump body 1, the pump body 1 is provided with an inlet pipeline 2 having an oil inlet 21 and a connection port 22, and the pump body 1 An oil inlet passage 3 , a pump chamber 4 , an oil outlet passage 5 and an oil outlet 6 are also arranged in sequence. The pump chamber 4 is provided with a hydraulic pump assembly 8 driven by a drive motor 7 .

[0021] The electric oil pump 100 can be used after being assembled with the filter 9 through the threaded connection shaft 10. After the assembly of the electric oil pump and the filter 9 is completed, the connection port 22 of the inlet pipeline 2 and the dirty oil of the filter 9 The end 91 communicates, and the oil inlet channel 3 communicates with the center pipe 92 (clean oil end) of the filter 9 through the threaded connection shaft 10 .

[0022] The above-mentioned hydraulic pump assembly 8 can be a plung...

Embodiment 2

[0026] Embodiment two is: as image 3 and Figure 4 As shown, an electric oil pump 200 with a bypass oil circuit includes a pump body 1, the pump body 1 is provided with an inlet pipeline 2 having an oil inlet 21 and a connection port 22, and the pump body 1 is also provided with An oil inlet passage 3, a pump chamber, an oil outlet passage 5 and an oil outlet 6 are arranged in sequence, and a hydraulic pump assembly 8 driven by a drive motor 7 is arranged in the pump chamber, and the oil inlet passage 3 and the outlet A bypass oil passage 11 is communicated between the oil ports 6 , and a bypass check valve 12 is arranged in the bypass oil passage 11 .

[0027] The electric oil pump can be used after being assembled with the filter 9 through the threaded connection shaft 10. After the electric oil pump and the filter 9 are assembled, the connecting port 22 of the inlet pipeline 2 and the dirty oil end of the filter 9 91 communicates, and the oil inlet passage 3 communicates...

Abstract

The invention discloses an electric oil pump which comprises a pump body, wherein an inlet pipeline with an oil inlet and a connecting opening is arranged in the pump body, and the connecting opening is used for being communicated with the dirty oil end of a filter; an oil inlet passage, a pump cavity, an oil outlet passage and an oil outlet which are sequentially communicated are also arranged in the pump body; the oil inlet passage can be communicated with a central pipe of the filter by a thread connecting shaft, and a hydraulic pump assembly driven by a drive motor is arranged in the pump cavity. Through the electrification of a manual oil pump, the invention easily solves the current problem of time and power waste when a driver uses the manual oil pump to replace a filter and shuts down to exhaust; and the invention adopts the structural design of oil pumping at the clean end and ensures the working stability of the electric oil pump.

Description

technical field [0001] The invention relates to an automobile part, in particular to an electric oil pump. Background technique [0002] In the fuel system of modern diesel engines, especially the high-pressure common rail system, hand oil pumps are widely used. The hand oil pump is generally assembled with the water separator to form a water separator assembly. Its main function is to discharge the air in the filter and fill the filter with diesel oil after the engine stops, so as to ensure that there is no leakage due to the filter. There is a large amount of gas in the tank and the engine cannot be started. There are also many drivers who are accustomed to using the hand oil pump to fill the filter when changing the filter, instead of filling the filter with diesel oil and then assembling it on the hand oil pump seat as required. In this way, the frequency of use of the hand oil pump is greatly improved, and relatively high requirements are put forward for the performan...
