Method and system for simply and efficiently injecting mercury into ultrahigh-voltage capillary tubular mercury lamp

Abstract

The invention relates to a method and a system for simply and efficiently injecting mercury into an ultrahigh-voltage capillary tubular mercury lamp. The method comprises the steps of injecting liquid mercury into a lamp tube directly through a mercury injector first and then exhausting air; and compared with the conventional method for exhausting air first and then injecting the mercury, the method has the advantages that: an indirect mercury-accommodating container, namely a mercury bulb, is eliminated, the links related to the mercury bulb are saved and the operation for enveloping and isolating the lamp tube is simplified. The system for injecting mercury comprises the mercury injector for injecting the mercury into the ultrahigh-voltage capillary tubular mercury lamp directly and an air exhausting cart for exhausting the air inside the ultrahigh-voltage capillary tubular mercury lamp filled with the mercury, wherein the mercury injector and the air exhausting cart are sequentially connected with each other. By the method and the system, the problems of complex procedures, time consumption and labor consumption, low working efficiency and the like of a method for injecting mercury by using an external mercury bulb are solved.

Description

technical field [0001] The present invention relates to lamp tube mercury injection technology, more specifically, relates to a mercury injection method and system for an ultra-high pressure capillary mercury lamp. Background technique [0002] The ultra-high pressure capillary mercury lamp is a kind of gas discharge lamp. Since this kind of lamp needs to be filled with necessary liquid mercury as the discharge substance when it is working, the method of filling liquid mercury into the discharge tube is called mercury injection. [0003] The current commonly used mercury injection method adopts the mercury injection method of external mercury bubble, including the following steps: [0004] 1. Inject mercury into a small quartz container (mercury bubble); [0005] 2. Connect the mercury bulb and the lamp tube to the exhaust port of the exhaust truck; [0006] 3. After exhausting and inflating, seal off the mercury bulb and the lamp tube together from the air extraction inte...

Problems solved by technology

[0008] In the actual operation of this method, each lamp tube corresponds to a mercury bubble filled with mercury, because the amount of mercury in each lamp tube is different, and each lamp tube needs to be in one-to-one correspondence with its mercury-filled mercury bubble, so the operation It is necessary to distinguish the independent labels of each lamp tube and mercury bulb, otherwise it is easy to be confused; when the lamp tube is connected to the exhaust car, it is necessary to connect the mercury bulb first, resulting in cumbersome procedures; there are mercury bubbles on the exhaust pipe before introducing mercury. It is easy to break the exhaust pipe during the process; after the exhaust of the lamp tube is completed, the mercury in the mercury bulb needs to be poured into the lamp tube again, which is time-consuming and laborious, and the work efficiency is low; Mercury injection error
