Abstract
The utility model belongs to a diesel engine detection device which comprises a constant pressure supply mechanism providing a nozzle with low pressure oil, a multi-hole nozzle, a beam-splitting oil collection part, a flow sensor and a processing and displaying part; the input end of the beam-splitting oil collection part is provided with a plurality of inlets to correspondingly connect with a plurality of orifices of the nozzle; the plurality of outlets of the output end of the beam-splitting oil collection part are corresponding with the inlets of the input end, and are respectively connected to the flow senor thereof through pipes; the measuring signal of the flow sensor is connected to the processing and displaying part. The utility model can judge the processing quality of the nozzle through uniformity detection of each orifice flow of the multi-hole nozzle coupled pair, therefore ensuring the quality of the products.
Description
The utility model belongs to the diesel engine pick-up unit, mainly proposes each spray orifice flow detection testing table of a kind of use for diesel engine perforated plate type atomizer.
The spray orifice flow is an important indicator of injector nozzle matching parts performance, and it directly has influence on dynamic property, economy and the emission behavior of diesel engine.At present, in domestic each oil nozzle manufacturer the total flow of perforated plate type atomizer idol part is measured, and can't be measured the flow value of each spray orifice.The size of each spray orifice flow value has directly reflected the machining precision and the cleanliness in this hole, and each orifice flow amount unevenness will cause the diesel engine performance variation when excessive, therefore tackles each spray orifice flow of perforated plate type atomizer idol part and measures.
The purpose of this utility model promptly is to propose each spray orifice flow detection testing table of a kind of use for diesel engine perforated plate type atomizer, detect the crudy of oil nozzle and whether have burr and dirty stifled phenomenon by measurement, thereby guarantee product quality each spray orifice discharge uniformity of perforated plate type atomizer idol part.
The utility model is finished the technical scheme that its invention task taked: detect testing table by the supplied with constant voltage mechanism that low pressure oil is provided for atomizer, perforated plate type atomizer, beam splitting oil-collecting parts, flow sensor and processing, display device constitute; Beam splitting oil-collecting parts input end has the corresponding connection of a plurality of spray orifices of a plurality of inlets and atomizer, and a plurality of outlets of its output terminal are corresponding with the inlet of input end, and is communicated with separately flow sensor by pipeline; The measuring-signal connection processing of flow sensor, display device.
The flow detection testing table that the utility model proposes utilizes beam splitting oil-collecting parts that each hole oil bundle of atomizer is collected respectively and its importing is independently measured in the flow sensor separately, treated and demonstrate each spray orifice flow number and total flow numerical value with digital form, display mode is chosen as single measurement or the multiple averaging value is measured.It detects the crudy of passing judgment on atomizer by the homogeneity to each spray orifice flow of perforated plate type atomizer idol part, thereby guarantees its product quality.
The utility model detection testing table also can be used for Diesel Engine Plant tests to the quality of buying oil nozzle, and the replacing number of times when installing to reduce oil nozzle is raised labour productivity.
Embodiment:
Accompanying drawing 1 is the utility model structural representation.
As shown in drawings, 1 for the supplied with constant voltage mechanism of low pressure oil is provided to atomizer 3, can be made up of fuel tank and oil pump; It provides low pressure oil stream by pipeline 2 for atomizer.The corresponding connection of a plurality of spray orifices of a plurality of inlets of beam splitting oil-collecting parts 4 input ends and atomizer 3, a plurality of outlets of its output terminal import corresponding flow sensor 5 with inlet is corresponding with the oil bundle, the measuring-signal connection processing of flow sensor 5, display device, measuring-signal is handled and shown, processing, display device can be central processing unit 6, nixie display 7.
