Abstract
The invention relates to a voltage stabilizing test warehouse, which comprises a warehouse body, an induced air segment and an air exhaust segment, wherein one end of the induced air segment is connected with the warehouse body, and the other end is connected with a rear main adjusting butterfly valve of an expander; an air entraining segment by stepless bleeding hot-air in proportion is arranged on the induced air segment, and a current stabilizing segment is arranged at the induced air segment close to the warehouse body; the warehouse body adopts a sealing structure, and is provided with a warehouse door; a temperature sensor is arranged in the warehouse body, and high-temperature-resistant glass observation windows are arranged on two sides of the warehouse body; and a video monitoring system is arranged outside the warehouse body. As a hot air input mechanism, a current stabilizing device, the high-temperature-resistant glass windows and the video monitoring system are arranged, the voltage stabilizing test warehouse can realize the stability of temperature and wind speed in the test process, the flame state of an igniter during low-temperature-point testing is conveniently observed, and accordingly, the whole testing process is monitored.
Description
Technical field
The present invention relates to a kind of voltage stabilizing test cabin.
Background technology
At aviation field, product will be tested under the different temperatures environment product before paying sometimes, verifies whether product is adapted to various abominable conditions of work.Need under-54 ℃ of environment, to carry out the test of air-fuel mixture low-temperature ignition such as certain aeromotor lighter, comprise that test(ing) medium (oil, gas), testpieces, test section etc. all need reach-54 ℃ and just can test, test required wind speed and divide 5 gradients, maximum wind velocity requires to reach 55m/s, and test condition is harsh.Generally speaking, the means such as acting drop in temperature externally expand by refrigerant switching technology, gas, set up the low-temperature test environment, but this low temperature environment such as direct use, can have then that temperature is unstable, fluctuations in wind speed is large, flame observable and the process of the test shortcoming that is difficult to monitor not during to the lighter ignition operation, makes the larger error of existence in the process of the test, precision and stability is poor, correctly the actual working state of evaluation test part ensures so need set up a journey new test storehouse.
Summary of the invention
Purpose of the present invention provides a kind of test cabin, and it is stable to be implemented in the process of the test temperature and wind speed, the flame status in the time of can observing easily the work of engine ignition device, and can monitor whole process of the test.
Technical scheme of the present invention is: test cabin comprises warehouse, the air inducing section, exhaustion section, described air inducing Duan Yiduan connects warehouse, main regulation butterfly valve behind the other end connection decompressor, be provided with in proportion stepless blending hot gas bleed section in the air inducing section, part at the close warehouse of air inducing section arranges a steady flow segment, this steady flow segment is the in proportion straight tube of 3～8 times of couplings of diameter and length, described warehouse is hermetically-sealed construction and is provided with door, be provided with temperature sensor in the warehouse, temperature sensor connects controller, described controller connects the hot-air valve, at the warehouse bilateral pyroceram view window is set, and video monitoring system is set outside warehouse.
The present invention in use, the cold air of decompressor output, by with the stepless ratio blending of hot gas, through behind the steady flow segment, form the air-flow of stablizing wind speed, enter test cabin, temperature sensor in the test cabin imports the temperature value of measuring into controller, and then come the hot gas amount of control inputs by the opening degree of hot-air valve, thereby the temperature of desired gas in the adjustment test cabin for ignition channel and the outside interlayer cooling duct of testing provides igniting and cooling desired gas, can be observed the test-fired flame situation of internal point firearm by the pyroceram window, simultaneously, monitor testing whole process by video monitoring system.
The present invention is by arranging hot-air input mechanism, constant-current stabilizer, pyroceram window and video monitoring system, can realize that temperature and wind speed are stable in the process of the test, flame status during easily observation point firearm low temperature experimental tests, and then whole process of the test monitored.
Fig. 1 is structural representation of the present invention.
