Abstract
The invention discloses a liquid nitrogen automatic conveying device which solves the liquid nitrogen supplementing problem of reliability test during the preparation process of infrared focusing plane detector component. The technical proposal is that a liquid storage tank with more volume is manufactured and connected with a liquid nitrogen tank of the equipment so as to form a communicating vessel, thus using the large nitrogen tank as the liquid nitrogen storage of the equipment, greatly increasing the liquid nitrogen storage quantity of the equipment and improving the liquid supplementing period.
Description
Technical field
Patent of the present invention relates to cryogenic technique, specifically is meant a kind of liquid nitrogen auto conveying device, is applicable in the infrared focus plane field in the focal plane component failtests.
Background technique
The HgCdTe infrared focal plane prober has more and more widely application at space flight, military affairs, industry and medical domain, and it has irreplaceable key effect at aspects such as national defence, national security and weather forecast.In order to improve the reliability of its work, prober is carried out high low temperature Cycle Screening and the low temperature aging test becomes conventional reliability growth work gradually.These tests all require the low temperature about the liquid nitrogen boiling point, usually use liquid nitrogen as cold temperature source in the industry, but because the liquid nitrogen liquid container volume of equipment itself is limited, need in the real work regularly to carry liquid nitrogen with supplement consumed to equipment.Under many circumstances, to reach twice above liquid nitrogen every day and replenish, waste time and energy very much, sometimes because fluid infusion cycle weak point, under the situation of continuous operation, require to add at weekend even night liquid nitrogen, this has restricted carrying out of this class reliability trial work greatly.
Summary of the invention
The purpose of this invention is to provide a kind of liquid nitrogen auto conveying device, solve the liquid nitrogen supplementary question in the detector module on focal plane of infrared ray reliability trial.
Technological scheme of the present invention is: make the bigger liquid container of a volume, the liquid nitrogen container that carries with equipment couples together, and forms connecting vessels, with the liquid nitrogen storage of this big liquid nitrogen container as equipment, has increased the liquid nitrogen memory space of equipment greatly, has improved the fluid infusion cycle.Accompanying drawing 1 is the structural drawing of apparatus of the present invention, fluid infusion liquid container 2 is placed on the support of sufficient intensity among the figure, equipment liquid container 10 is fixed on the equipment interface, the liquid level that guarantees fluid infusion liquid container 2 is higher than the liquid level height of self liquid container, makes liquid nitrogen flow into the equipment self liquid container automatically in liquid supply device.Connect with vacuum tube 4 between two containers, joint uses flange 5 sealings, and coated outside one deck heat insulation layer 3 is at last again with detachable safety cover 6 fixing protections.The effect of adiabatic stopper 9 is sealings and adiabatic among the figure, prevents that liquid nitrogen from revealing, heat dissipation, and two vacuum tubes insert liquid container by this adiabatic stopper, and vacuum tube 8 is an outlet pipe, and vacuum tube 4 is an indusion tube.Indusion tube couples together equipment self liquid container and liquid supply device liquid container, forms connecting vessels, and outlet pipe has guaranteed the pressure balance of whole system and atmosphere.
The invention has the advantages that: device for prolonging the fluid infusion cycle of equipment, make the utilization of equipment more flexible, improved the utilization efficiency of equipment.
