The present invention relates to a method for determining the time for maintenance and repair of a vacuum pump or a cryogenic blower, which can supply fluid into a thermal vacuum chamber for a thermal vacuum test of a satellite and is provided with a coolant channel therein for cooling. To this end, provided in the present invention is the method for determining the time for maintenance and repair of a vacuum pump or a blower for a thermal vacuum chamber of a satellite, which comprises: a coolant supply pipe (10) which supplies a coolant to a coolant channel; a coolant discharge pipe (20) which discharges the coolant from the coolant channel; and a first flow amount switch (S1) and a second flow amount switch (S2) which are provided at the coolant discharge pipe (20). In addition, the present method further comprises: an alarming step of enabling, when the first flow amount switch (S1) detects a flow amount flowing in the coolant discharge pipe to be under a first flow amount, a control unit to send an alarm for maintenance and repair of a vacuum pump or a cryogenic blower; and a stopping step of enabling, when the second flow amount switch (S2) detects the flow amount flowing in the coolant discharge pipe to be under a second flow amount, the control unit to send an emergency stopping command to the vacuum pump or the cryogenic blower.

    본 발명은, 인공위성의 열진공 시험을 위한 열진공챔버 내부로 유체를 공급하며, 내부에는 냉각을 위한 냉각수 채널을 구비한 진공펌프 내지 극저온 블로워의 유지보수시기를 결정하는 방법으로서, 상기 냉각수 채널로 냉각수를 공급하는 냉각수 공급관(10); 상기 냉각수 채널에서 냉각수를 배출하는 냉각수 배출관(20); 및 상기 냉각수 배출관(20)에 구비되어 제1유량스위치(S1)와 제2유량스위치(S2);를 이용하여, 상기 제1유량스위치(S1)가 상기 냉각수 배출관을 흐르는 유량이 제1유량 이하임을 감지하면, 제어부가 진공펌프 내지 극저온 블로워 유지보수를 위한 알람을 울리는 경고단계;와 상기 제2유량스위치(S2)가 상기 냉각수 배출관을 흐르는 유량이 제2유량 이하임을 감지하면, 상기 제어부가 상기 진공펌프 내지 극저온 블로워를 비상정지 명령을 내리는 정지단계;로 이루어지는, 인공위성 열진공 챔버용 진공펌프 내지 블로워의 유지보수시기 결정방법을 제공한다.
