Abstract

The utility model relates to a cooling nozzle targeting testing device which is characterized in that the testing device includes an oil storage box used to store the oil liquid and an oil outlet pipe which is led out from the oil storage box; the oil outlet pipe is connected with a pressure adjuster; an oil outlet of the pressure adjuster is connected with a pressure gauge via an oil pipe; an output terminal of the pressure gauge is connected with a cylindrical support which is used to fixedly arrange a to-be-tested cooling nozzle via the oil pipe; the bottom of the cylindrical support is provided with a pedestal; the pedestal is provided with a targeting jet hole which is corresponding to the cooling nozzle; an oil collecting box is arranged below the targeting jet hole. Through the above structure, an oil beam is diverged in different degrees at a nozzle hole under different pressures. If the oil beam is seriously diverged under a specified pressure, and the oil beam can not pass through the targeting jet hole completely, the cooling nozzle is not qualified. The targeting test of multiple nozzles can be carried out repeatedly. The cooling nozzle targeting testing device can guarantee that each cooling nozzle arranged on an engine can work effectively. The cooling nozzle targeting testing device has the advantages of simple structure, convenience of use, accurate testing, improved product qualified rate, and the like.

Description

A kind of cooling jet target practice test unit
Technical field
The utility model belongs to engine check frock field, particularly a kind of verifying attachment that is used to check the correct target practice of cooling jet.
Background technology
When diesel engine design, along with the raising of engine capacity, piston is done manual work to be increased, and the piston cooling seems particularly important.Generally, a kind of more effective type of cooling promptly is cast with cooling oil duct in piston, and cooling jet spray machine oil cools off piston in cooling oil duct.In the engine use, if cooling jet can not accurately spray machine oil in the oilhole of piston cooling oil duct, will cause a series of faults such as the molten top of piston scuffing of cylinder bore, failure effect is very serious.Each nozzle that must guarantee to be installed on the engine can spray machine oil according to design discharge accurately; Even it is qualified cooling jet that nozzle merchant guarantees to dispatch from the factory; But in transportation, possibly cause some nozzle defective, but let us can not find with range estimation.To above situation, it is very necessary to invent a kind of installation front nozzle target practice test unit, and this device is simple to operate, has solved the problem of the defective cooling jet of misloading.
Summary of the invention
The utility model provides a kind of simple in structure, easy to use, test accurately for solving the technical matters that exists in the known technology, improves the cooling jet target practice test unit of product percent of pass.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
A kind of cooling jet target practice test unit; It is characterized in that: this test unit comprises the oil storage box of a fluid; Saidly draw flowline from oil storage box, said flowline connects pressure governor, and the oil-out of said pressure governor connects tensimeter through petroleum pipeline; Manometric output terminal connects through oil pipe and is used for fixing the cylindricality support of placing cooling jet to be detected; The lower end that said cylindricality supports is provided with base, and base is provided with the target practice jet orifice corresponding with cooling jet, and the below of target practice jet orifice is provided with swab case.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme; To at first correctly cooling jet be installed and support in cylindricality, can control flow rate of lubricating oil under the different pressures through regulating tensimeter then, nozzle bore place ejection oil bundle has dispersing in various degree under different pressures; If oily Shu Yanchong disperses under the pressure of regulation; Can not be all through the target practice jet orifice, then this cooling jet is defective, can carry out the target practice test of a plurality of nozzles repeatedly.Each cooling jet that this device assurance is installed on the engine can effectively be worked.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, oil storage box; 2, swab case; 3, flowline; 4, pressure governor; 5, petroleum pipeline; 6, tensimeter; 7, cooling jet; 8, cylindricality supports; 9, base; 9-1, target practice jet orifice.
Embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1, a kind of cooling jet target practice test unit, this test unit comprises the oil storage box 1 of a fluid; Saidly draw flowline 3 from oil storage box 1; Said flowline 3 connects pressure governors 4, and pressure governor can provide hydraulic oil, simultaneously also can the set pressure size; This pressure governor belongs to known products, and its concrete structure is not in this too much description.The oil-out of said pressure governor 4 connects tensimeter 6 through petroleum pipeline 5; The output terminal of tensimeter 6 connects through oil pipe and is used for fixing the cylindricality support 8 of placing cooling jet 7 to be detected; The lower end of said cylindricality support 8 is provided with base 9; Base 9 is provided with the target practice jet orifice 9-1 corresponding with cooling jet 7, and the below of target practice jet orifice 9-1 is provided with swab case 2, in like manner also can be with oil storage box as reclaiming fluid.
Method of application; Cooling jet at first correctly is installed is supported in cylindricality, can control flow rate of lubricating oil under the different pressures through regulating tensimeter then, nozzle bore place ejection oil bundle has dispersing in various degree under different pressures; If oily Shu Yanchong disperses under the pressure of regulation; Can not be all through the target practice jet orifice, then this cooling jet is defective, can carry out the target practice test of a plurality of nozzles repeatedly.Each cooling jet that this device assurance is installed on the engine can effectively be worked.
