Description
Technical Field
The utility model belongs to VP pump low pressure oil feeding system field especially relates to a VP pump body suitable for IV stage on non-road.
Background
According to the emission regulation of the fourth IV stage of the non-road state, the requirements of the environmental protection department are met, the emission regulation can not be met by an original VE pump, an oil injection system such as a full electric control VP pump can be used, when the EVP-1 type electric control VP pump of our company is matched with engine models such as 493 of the IV stage of the non-road state, a sensor on one side of a piston cavity of the VP electric control pump has an interference phenomenon in the installation process, and due to the fact that the sensor is installed at the upper end of the piston cavity of the original pump body, when a piston moves in the piston cavity, the sensor possibly collides with a connecting part at one end of the sensor, a phenomenon that oil leaks from a high-pressure cavity exists, and therefore a VP pump body suitable for the IV stage of the non-road state needs to be designed to solve the problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to the technical problem who exists among the prior art, provide a VP pump body suitable for IV stage on non-road, concrete technical scheme is as follows:
the utility model provides a VP pump body suitable for IV stage on non-road, including pump body structure, pump shaft neck structure is installed to the front end of pump body structure, pump shaft neck structure with install the flange structure between the pump body structure, piston cavity structure is installed to one side of pump body structure, electromagnetism valve cavity structure is installed to one side of piston cavity structure, and the sensor is installed to one side in addition, the sensor is through installing the structural threaded lug of pump body is fixed, the apron structure is all installed at the upper and lower both ends of piston cavity structure, the apron structure is installed through the screw mode the piston cavity is structural.
The utility model discloses a further improvement lies in: and a limiting opening structure is arranged between the upper part of the sensor and the edge of the piston cavity structure.
The utility model discloses a further improvement lies in: the limiting opening structure is of a semicircular structure and is used for guiding the sensor wire harness and preventing the sensor wire harness from rubbing with a sharp edge of the pump body.
