Description

Technical Field

[0001] The utility model relates to the technical field of oil delivery pumps, in particular to a constant force electric oil delivery pump. Background Art

[0002] The oil pump is a device used to transport liquids, mainly used to transport fuel, lubricating oil, hydraulic oil and other liquids. Its function is to ensure that a sufficient amount of liquid is transported from one place to another, and to maintain a certain pressure to overcome the resistance of the pipeline and liquid filter. During the use of oil transportation, the oil pump needs to be fixed. When the existing oil pump is used, it is generally fixed in a suitable position. When the position of the oil pump needs to be replaced, it is not convenient to disassemble the oil pump, which affects the use effect.

[0003] According to the description of an electric oil pump with a connecting bracket published on the patent website (authorization announcement number: CN205936914U), the electric oil pump with a connecting bracket includes "a housing, a flange, a fixing sleeve, a positioning plate", etc. to fix the oil pump.

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] The electric oil pump with a connecting bracket uses a shell, a flange, a fixing sleeve, a positioning plate, etc. to fix the oil pump. However, when the oil pump is in use, a formed flange and a plug-in sleeve fixing sleeve are provided on the oil pump. The oil pump can be fixed by connecting the fixing sleeve with an adjusting bolt. However, most oil pumps do not have a formed flange and a plug-in sleeve fixing sleeve. This fixing method cannot be applied to other oil pumps, has a poor use effect, and the fixing method cannot ensure the stability of the oil pump. Therefore, it is necessary to improve this oil pump.
