Problems solved by technology

The traditional oil pump will cause pressure instability due to temperature rise or the influence of backflow, especially at the oil outlet end of the oil pump. If the oil outlet end is not stabilized, the oil pressure at the oil outlet end will easily increase. , over time, it affects the seal of the oil outlet, so that there is a certain degree of safety problem

Embodiment Construction

[0029] refer to Figure 1 to Figure 3 An embodiment of an oil pump with an anti-leakage device and an oil leakage detection method thereof according to the present invention will be further described.

[0030] For ease of description, if spatially relative terms such as "upper", "lower", "left", and "right" are used in the embodiments, they are used to describe the relative relationship between one element or feature shown in the figure and another element or feature Relationship. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degr...

Abstract

The invention discloses an oil pump with an anti-leakage device and an oil leakage detection method thereof, and aims to provide an oil pump with good anti-leakage effect, simple structure and strong practicability. As well as the oil outlet, it also includes a leak-proof detection device. The leak-proof detection device includes an external fuel pipe connected to the oil outlet, and a monitoring mechanism arranged in the external fuel pipe. Determining whether oil leakage occurs in the external fuel pipe forms a good monitoring effect and facilitates timely prevention. The invention is suitable for the technical field of auto parts.

Description

technical field [0001] The invention relates to the technical field of auto parts, more specifically, it relates to an oil pump with an anti-leakage device and an oil leakage detection method thereof. Background technique [0002] The function of the gasoline pump is to supply the fuel required by each injector and cold start injector. There are generally two types of electric gasoline pumps used in electronically controlled gasoline injection systems, namely roller electric gasoline pumps and vane electric gasoline pumps. Roller type electric gasoline pump, one end of the pump casing is the oil inlet, and the other end is the oil outlet. The roller pump on the side of the oil inlet is driven at high speed by the drive motor in the middle of the pump casing. The rotor is installed eccentrically in the pump body, and the rollers are installed in the grooves of the rotor. [0003] When the oil pump rotates, due to the action of centrifugal force, the rollers in the rotor gr...
