Engine hole type oil nozzle single-hole extruding and grinding device and use method

Abstract

The invention discloses an engine hole type oil nozzle single-hole extruding and grinding device and a use method. The engine hole type oil nozzle single-hole extruding and grinding device comprises an oil nozzle seat, an oil nozzle body and a shaft needle single-hole circulation rod sleeve which is arranged in the oil nozzle body and can rotate. A ball head at the bottom of the shaft needle single-hole circulation rod sleeve is provided with a rod sleeve spraying hole which can be communicated with any oil nozzle spraying hole after rotating, a sealing face is arranged between the ball head and the oil nozzle body, and the bottom of the oil nozzle seat is further connected with at least one working liquid box through a discharging electromagnetic valve. By means of the structure and the method, the shaft needle single-hole circulation rod sleeve can rotate and drive the rod sleeve spraying hole to rotate so that the rod sleeve spraying hole can be communicated with any oil nozzle spraying hole, and flow or spraying characteristic detection or uniformity evaluation or repairing operation can be conducted on any independent oil nozzle spraying hole. Due to the multiple working liquid boxes, the discharging electromagnetic valve and the like, fast switching of flow detection or grinding or cleaning operation can be achieved by directly controlling the actions of feeding and discharging electromagnetic valves.

Description

technical field [0001] The invention relates to an engine fuel injector nozzle processing device and a using method thereof, in particular to a single-hole extrusion grinding device and a using method of an engine hole type fuel injector nozzle. Background technique [0002] Energy crisis and environmental pollution are two major problems facing the world today, and the engine consumes a lot of fuel energy and emits a lot of harmful gas pollutants, which is the main producer of energy and environmental problems, so how to improve the fuel of the engine Utilization efficiency and reduction of harmful emissions are of great significance. [0003] In the engine, the injection effect of the fuel injection system directly affects the utilization rate of fuel and the emission of harmful gases, and the fuel injector is one of the important components in the fuel system. have a very important impact. With the wide application of common rail technology, fuel injectors are also grad...

AI Technical Summary

Problems solved by technology

If the nozzle flow coefficient is not up to the standard, repeated liquid extrusion and grinding will have great randomness in the shaping of the nozzle holes. At the same time, it is impossible to repair the shape and structure of a single nozzle hole. When the requirements are high and the nozzles cannot meet the requirements, scrap and reprocess new nozzles. When the nozzle flow detection test bench is used to detect the flow of the nozzle, the flow rate of a single nozzle hole and the flow rate between each nozzle hole cannot be measured. The flow uniformity of the test and evaluation has great limitations
