Abstract
The present invention discloses a high temperature gas pressure test method which is realized by a pressure sensor (1), a sampling adapter (3) and a pressure guide medium (6). The pressure in a high temperature gas transmission pipeline is transmitted to the pressure sensor (1) via the pressure guide medium in a pressure guide hole of the sampling adapter (2), and during the transmission process, the guide pressure medium of the sampling adapter (3) is cooled by cooling water. The method of the present invention solves the failure problem of a high temperature gas pressure test sensor, enables the cost of the high temperature gas pressure test sensor to be reduced, the zero drift of the pressure sensor caused by temperature to be reduced, and the test precision to be improved.
Description
Technical field
The present invention relates to a kind of method for testing pressure, particularly a kind of high-temperature fuel gas method for testing pressure
.
Background technology
In the test in the fields such as Aeronautics and Astronautics, the pressure of combustion gas while needing test engine igniting, the temperature of engine gas can arrive more than 1000 DEG C, the scope of application of present usual pressure sensor is not higher than 70 DEG C, the scope of application of high-temperature-resistance pressure sensor is not higher than 500 DEG C, and its resistance to elevated temperatures is higher, its manufacturing cost is just higher.These two kinds of sensors are when for high-temperature fuel gas pressure test, and high temperature passes to pressure transducer sensitive area by heat insulation medium, thereby make pressure transducer have larger zero drift, and test error more even makes sensor failure, does not reach test request.
Summary of the invention
The object of the invention is to provide a kind of high-temperature fuel gas method for testing pressure, solves the problem of high-temperature fuel gas pressure test sensor failure.
A kind of concrete steps of high-temperature fuel gas method for testing pressure are:
The first step is installed sampling adapter
Employing has the sampling adapter of cylindrical cavity body structure, and sampling adapter one end is pressure guide hole, and the sampling adapter other end is that pressure transducer is installed threaded hole.On high-temperature fuel gas transmission pipeline, offer the threaded hole of a conducting, the pilot nose end of sampling adapter is connected with the threaded hole of high-temperature fuel gas pipeline, pressure guide hole length is greater than 5cm, aperture is less than 3mm, in hole, fill 320 DEG C～1200 DEG C high temperature resistant railway grease as pilot medium, pilot medium prevents the direct contact pressure sensor sensitive area of high-temperature fuel gas simultaneously.Sampling adapter pressure transducer is installed end face machined grooves, and the embedded O shape of groove rubber washer, seals.
The cooling pilot medium of second step
The water inlet of sampling adapter connects running water pipe with plastic tube, and due to the pressure-acting of tap water, tap water flows out from water delivering orifice after the circulation of sampling adapter cooling chamber.High-temperature fuel gas transmission pipeline internal pressure conducts to the sensitive area of pressure transducer by the pilot medium in sampling adapter pressure guide hole, in conductive process, utilize tap water to carry out cooling to the pilot medium of sampling adapter.
So far completed high-temperature fuel gas pressure test.
This method has solved the problem of high-temperature fuel gas pressure test sensor failure, has reduced the cost of high-temperature fuel gas pressure test sensor, and the pressure transducer zero point drift that has reduced to be caused by temperature improves measuring accuracy.
