Incubator aperture 11 can the inert gas such as nitrogen injection and helium as protective gas, to provide the experimental enviroment of stabilization.
Experiment one：
During upper couple is for the friction-wear test of ice pin, air inlet pipe 14 and the cooling external refrigerating plant of escaping pipe 10, refrigerant are cooled down
Flowed in copper pipe and low temperature friction wear testing machine is freezed, the upper vent hole 17 of original state outer layer thermal-insulating body 31,
Lower passage 22 is closed, and the frost part charging hole 1 on right side is closed, and outer layer incubator aperture 11 is closed, internal layer incubator aperture 27
Close, internal layer thermal-insulating body 7 is opened, and now, internal layer thermal-insulating body 7 is connected with the space of outer layer thermal-insulating body 31, protected by internal layer
Refrigeration copper tube heat exchange in incubator is realized to two refrigeration of cavity, because the larger refrigeration of cavity volume is slow.Work as outer layer
Temperature sensor 5,19 in thermal-insulating body 31 is when displays temperature is -2 DEG C on display module 9 is controlled, the frost on the right side of opening
Part charging hole 1, sends the ice pin 28 for being preserved in cryogenic box in advance into frost part charging hole 1, and ice pin 28 is slided under gravity
To horizontal stand, now rapid to close frost part charging hole 1, ice pin 28 is in -2 DEG C of environment will not be melted, and both hands put on one's gloves
The operation leather glove put on outer layer incubator chamber door 33 is operated, and opens illuminating lamp 8, clamping ice pin, finishing and by internal layer
Thermal-insulating body 7 is closed, and at this moment, only to lowering the temperature in internal layer thermal-insulating body 7, the cooling space cooling rate that diminishes adds cooling tube
Hurry up, until temperature needed for experiment, internal layer thermal-insulating body is observed after closing inner thermal insulating layer casing 7 by endoscope and illuminator 18
Working condition in 7.
In experiment, ice pin 28 effectively prevent thawing in -2 DEG C of environment during clamping, and staff is grasped in -2 DEG C of environment
Work also will not frostbite.
Experiment two：
During upper couple is the low temperature friction-wear test of non-ice pin, clamping can be fulfiled ahead of schedule, however it is necessary that providing protective gas
Working environment removing steam.
Outer layer incubator upper vent hole 17, lower passage 22 and frost part charging hole 1 are opened during original state, internal layer insulation
Casing 7 is closed, and dry protective gas is input into from outer layer incubator aperture 11, and leather hose 20 is connected with internal layer incubator aperture 27,
Now dry protective gas continually enters internal layer thermal-insulating body 7, is required because friction wear testing machine is eccentric, internal layer incubator
Partly there is the slotted eye of non-close on body, dry protective gas is from bottom to top by the air in internal layer thermal-insulating body 7 from slotted eye
Extrude.
When the measured value of moisture detection sensor 30 reaches 0 in internal layer thermal-insulating body, dry protective gas is protected from outer layer
The upper vent hole 17 of incubator body enters, and now outer layer thermal-insulating body aperture 11 remains unchanged and keeps the input of protective gas, dry guarantor
Shield gas extrudes the air in outer layer thermal-insulating body 31, lower passage 22 and frost part charging of the air from external thermal insulation casing
Discharge in hole 1.
When the moisture detection sensor 25,4 in the lower passage 22 and frost part charging hole 1 of outer layer thermal-insulating body 31 is measured
When value all reaches 0, leather hose 20 is separated with internal layer incubator aperture 27 by operating leather glove, and cover internal layer incubator aperture
Lid 21, puts the lid 3 on passage port lid 23 and frost part charging hole 1 under outer layer incubator, then stops supply protection gas
And outer layer incubator upper vent hole lid 16 and the small port lid 13 of outer layer incubator are covered, now, drying is filled with the cavity of closing
Protection gas, illuminating lamp 8 is opened all the time in operating process, then turn on cryogenic system start cooling, during experiment pass through endoscope
And the observation working condition of illuminator 18,.
In experiment, can reflect the full situation of protective gas and effectively eliminate moisture low indirectly by detecting moisture
Influence under temperature to testing, the inwall spheroid shape of outer layer thermal-insulating body 31 is conducive to gas to flow, it is to avoid right angle, it is not easy to form dead
Angle, cooling cavity is always less internal layer thermal-insulating body 7, and cooling rate is very fast.
Part that the present invention does not relate to is same as the prior art or can be realized using prior art.
