Abstract

The invention relates to an internally heated getter pump. The pump comprises a plurality of air suction elements 1, a supporting body, positioning plates 5 and a base 6. The supporting body comprisesa central supporting bar 2 and a cylindrical hollowed-out thin shell 4. The central supporting bar 2 is connected with the cylindrical hollowed-out thin shell 4 through one positioning plate 5. The positioning plates 5 and the cylindrical hollowed-out thin shell 4 are fixed to the base 6 through the central supporting bar 2. A pump body is provided with the multiple air suction elements 1 which are uniformly fixed to the positioning plates 5 through thin metal bars 11 correspondingly. The base 6 is a high vacuum CF flange and is connected with the pump body central supporting bar 2 in a threaded form and connected with heating systems and thermocouples in the pump body and an external power supply by embedding four vacuum electrodes 7 in the base through kovar alloy. The internally heatedgetter pump provided by the invention adopts the internal heating column shaped air suction elements and is high in heating efficiency, uniform in exciting and high in air suction speed.

Description

technical field [0001] The invention relates to an internal heating type getter pump, which belongs to the field of vacuum technology. It can be used to obtain or maintain an ultra-high vacuum state. Background technique [0002] The getter pump gets rid of the traditional configuration of the vacuum pump, and uses the alloy material as the getter to combine with the active gas, which can remove the main residual gases hydrogen and carbon monoxide in the ultra-high vacuum system, so as to obtain and maintain the ultra-high vacuum degree of the system. It has a series of advantages such as high pumping speed, clean and oil-free, no moving parts, no vibration, room temperature pumping, and low energy consumption. [0003] The early structure of the getter pump is to roll or coat the getter material on the metal nickel or nickel-plated iron base strip. This structure has a large suction area and a large suction speed. However, the getter material has poor vibration resistance...
