Embodiment
With reference to explanation accompanying drawing 1, it shows a kind of high-temperature vacuum solar collector pipe vacuum leak hunting proving installation, and it comprises:
Vacuum system is used to form the required vacuum tightness of vacuum tube to be detected, and is provided with vacuum meter 7;
Station is connected to said vacuum system through valve, so that vacuum tube to be detected is detected;
Detect source of the gas, be connected to said station through vacuum system through valve; And
Leak locator 2 is connected to said station through valve through said vacuum system.
About required vacuum tightness, be not the technological point of this programme, and the parameter that relates to process aspect is confirmed, can be confirmed by the technical parameter of leak locator here, this is the right and wrong problem of usually seeing all.
The station here also is meant the detection station.
As for the protection source of the gas, also be the equipment that cooperates leak locator mainly, such as source nitrogen, further, said detection source of the gas is a nitrogen pot 3.
Said vacuum system comprises the gas-holder 4 that is provided with tensimeter 8, and this gas-holder inserts the main line of vacuum system through valve, and connects the parts of said protection source of the gas as this vacuum system.Charge into detect blanket gas can avoid managing in vacuum tightness low excessively; Cause malaria to get in the pipe, getter can not make little inefficacy very soon, guarantees that the heat waste of thermal-collecting tube can significantly not reduce; Serviceable life can be long, and then guarantee the sustainability of the operational efficiency of thermo-power station.,, can construct the opening and closing time of suitable vacuum plant through the control of valve.Tensimeter then provides reference, through the amount of gas in the control gas-holder, makes the pressure that feeds behind the high temperature pipe remain on 1 atmospheric pressure.
Preferably; The vacuum source parts of said vacuum system are for being connected to the oil-sealed rotary pump 1 of main line through valve; The final vacuum of single-stage oil-sealed rotary pump is at 10-1Pa; Can satisfy the normal operation of system fully, mouthful highest pressure of the permission of leak locator leak detection simultaneously generally at 1000Pa once also can satisfy.
