Abstract
The utility model relates to a testing device of an engine air compressor. The technical scheme provided by the utility model is as follows: the testing device of the engine air compressor comprises a main pipeline capable of being communicated with the air compressor; the main pipeline is communicated with an air storage cylinder; a pressure gauge and a safety valve are arranged on the air storage cylinder; a first valve is arranged on the main pipeline; a front unloading pipeline is arranged on the main pipeline in the front of the first valve; a second valve is arranged on a front branch pipeline; and both the first valve and the second valve are electrically connected with a time relay. The testing device of the engine air compressor disclosed by the utility model has the benefits of being capable of simulating a working condition, solving the problems of being incapable of carrying out an effective reliability test on a testing rack of the air compressor and the like, finding out the problems of the air compressor as early as possible before volume production of the whole testing device, and effectively improving the problems.
Description
Technical field
The utility model is a kind of test unit of engine air press.
Background technology
It is that air drum for car load provides source of the gas that air compressor machine on the engine mainly acts on, and air compressor machine is driven by motor-driven gear, and rotation and train through bent axle pass to air compressor machine with driving force, thereby realize the acting of air compressor machine.Yet air compressor machine lacks effective checking means as one of key components and parts on the engine always when parts carry out fail-test, is empty race the under the non-loaded situation.Thereby a lot of problems fail when whole aircraft reliability test, effectively to be verified, cause air compressor machine a lot of problems in actual application, to occur, and user's use is all brought inconvenience, and also cause very big economic loss and negative social influence to main engine plants.
Summary of the invention
The technical matters that the utility model will solve provides a kind of testing equipment of engine air press; It can simulated condition; Solve air compressor machine and can not do problems such as effective fail-test, can the problem of air compressor machine found before the complete machine volume production as early as possible and effectively improved at test-bed.
The utility model is realized through following technical measures: a kind of test unit of engine air press; It comprises the main line that can be communicated with air compressor machine, and said main line is communicated with air drum, and said air drum is provided with tensimeter and safety valve; Said main line is provided with valve one; Main line before the said valve one is provided with preceding offloading pipeline, said before bye-pass be provided with valve two, said valve one, valve two all are electrically connected with the time relay.
The concrete characteristics of the utility model also have, and the main line behind the above-mentioned valve one is provided with the back offloading pipeline, and said back offloading pipeline is provided with valve three, and said valve three is electrically connected with tensimeter.
Above-mentioned tensimeter is the contact tensimeter.
The beneficial effect of the utility model can be known through foregoing description; It is skillfully constructed, with low cost; Easy to use; Can simulated condition, solve air compressor machine and can not do problems such as effective fail-test at test-bed, can the problem of air compressor machine be found before the complete machine volume production as early as possible and effectively improved.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Among the figure, 1, air compressor machine, 2, the time relay, 3, safety valve, 4, the contact tensimeter, 5, valve one, 6, valve two, 7, valve three, 8, air drum.
Embodiment
For clearly demonstrating the technical characterstic of this programme, through an embodiment, this programme is set forth below.
Shown in accompanying drawing, a kind of test unit of engine air press, it comprises the main line that can be communicated with air compressor machine; Said main line is communicated with air drum; Said air drum is provided with contact tensimeter and safety valve, and said main line is provided with valve one, and the main line before the said valve one is provided with preceding offloading pipeline; Bye-pass is provided with valve two before said, and said valve one, valve two all are electrically connected with the time relay.Main line behind the valve one is provided with the back offloading pipeline, and said back offloading pipeline is provided with valve three, and said valve three is electrically connected with tensimeter.
During experiment, the work that air compressor machine does not stop along with the running of engine can decide air compressor machine to inflate according to the Push And Release of time relay operation valve one and valve two in the course of work and enter air drum or be discharged to atmosphere.Wherein, when valve one was opened, gas got into air drum, is equivalent to like this load to air compressor machine; And valve one cuts out, when valve two is opened, gas flows in the atmosphere, air compressor machine is equivalent to zero load like this, adjusts air compressor load factor survey through the time relay.
Suppose that contact tensimeter that air drum the connects force value of setting up an office is 8bar, when promptly pressure reached 8bar, valve three was opened automatically, and the gas of air drum will be emitted like this, thereby simulates the situation of car load use source of the gas.In addition, air drum need be worn a safety valve, and when tensimeter or valve three break down when can not normally lose heart, safety valve is opened, and guarantees the safety of air drum and surrounding enviroment.
The utility model can pass through or adopt existing techniques in realizing without the technical characterictic of describing; Repeat no more at this; Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited in above-mentioned giving an example; Variation, remodeling, interpolation or replacement that those skilled in the art are made in the essential scope of the utility model also should belong to the protection domain of the utility model.
