With reference to Fig. 1-Fig. 3, wherein Fig. 3 can be considered and discloses a kind of sealing property method of testing in the lump, and this tightness testing method comprises the following step:
1) Open valve I2 closes other valves, opens air compressor 1, treat that surge tank 4 internal pressures increase to 0.5MPa after, open valve II5, the moisture that deposit in the surge tank that will test last time 4, dirt etc. pass through pipeline
3 emptyings (step 31) to surge tank;
2) tested mechanical rapping apparatus raised-face flange 27 is installed on the test cylindrical shell raised-face flange 28 by the bolt pad, metal hose 17 is connected with tested mechanical rapping apparatus air intake opening 26, the gas channeling end cap 23 of the pick-up unit 22 that leaks outside is installed in tested mechanical rapping apparatus piston waveguide tube 21 ends (step 32);
3) Open valve I2, valve
9, valve
10, close other valves, open the electric heater on air compressor 1, surge tank 4 and the test cylindrical shell 11, make surge tank and the interior gaseous tension of test cylindrical shell and temperature increase to predetermined pressure and temperature (step 33), described predetermined pressure range is: 3.5MPa ~ 4.0MPa, and predetermined temperature is: 250 ℃ ~ 270 ℃;
4) by test cylindrical shell 11 upward pressure sensors and temperature sensor monitors test cylindrical shell 11 internal pressures and temperature, wait to reach pre-provisioning request after, heat-insulation pressure keeping 5min(step 34);
5) emit the bubble situation in the water tank 25 in observation and the recording step 34, if there is continuous bubbling phenomenon to produce in the water tank, namely there is defective in these tested mechanical rapping apparatus 20 external seals, are substandard product; If no continuous bubbling phenomenon produces in the water tank 25, namely tested mechanical rapping apparatus 20 does not have leakage (step 35) to outside atmosphere;
6) further tested mechanical rapping apparatus 26 is carried out the inner sealing performance test: Open valve
2, valve
10, close other valves, keep test cylindrical shell 11 interior temperature and pressure constant, open air compressor 1, treat surge tank 7 inner air pressures and temperature increase to predetermined lifting values, heat-insulation pressure keeping schedule time 30min; Specifically, step 36 is actually by improving surge tank 4 internal pressures comes the pressure of air in lift line IV14 and the tested mechanical rapping apparatus air intake opening 26, should predetermined lifting values be 0.5MPa ~ 0.6MPa, be that pipeline IV14 inner air pressure is tested cylindrical shell 21 internal pressures and wanted high 0.5MPa ~ 0.6MPa, simultaneously, prevent decrease of temperature (step 36,37) in surge tank 4 and the test cylindrical shell 11 by electric heater;
7) situation of change of last micro-flowmeter 13 indicating values of pipeline IV14 in observation and the recording step 37, specifically, the indicating value of micro-flowmeter 13 is namely represented the mobility status of gas medium in pipeline IV14, under the predetermined pressure difference effect, pipeline
Gas will flow in test cylindrical shell 11 by tested mechanical rapping apparatus 20 inner structures in 14, and the indicating value of micro-flowmeter 13 is tested mechanical rapping apparatus 20 by the size of its air intake opening 26 toward test cylindrical shell 11 internal leakages; Simultaneously, observe and recording step 37 processes in the situation (step 38) of bubble in the water tank 25;
8) if micro-flowmeter 13 maximum indicating values are greater than 0.5g/min in the step 38, show that there is the defective of interior seal leakage in this tested mechanical rapping apparatus 20, is substandard product; If smaller or equal to 0.5g/min, judge that according to this tested mechanical rapping apparatus air intake opening 26 meets technical requirement to test cylindrical shell 11 internal leakage situations, namely interior sealing is qualified; Simultaneously, if no continuous bubbling phenomenon generation in the water tank 25 in the step 38, then tested mechanical rapping apparatus 20 external seals of this platform meet the requirements; The lattice if these tested mechanical rapping apparatus 20 interior external seals are combined can be judged these tested mechanical rapping apparatus 20 sealing properties qualified (step 39,40);
9) finish inside and outside sealing property test after, close other all valves, Open valve V16 makes test cylindrical shell 11 internal gas pressures by pipeline V15 and pipeline
14 internal gas pressures reach balance, slower Open valve
19, make the interior gas of test cylindrical shell 11 and pipeline IV14 pass through pipeline simultaneously
18 drain into ambient atmosphere, the damage that step 36 causes tested mechanical rapping apparatus 20 because of the pressure differential that produces between test cylindrical shell and tested mechanical rapping apparatus air intake opening when avoiding pressure release; Specifically, if test cylindrical shell 11 is asynchronous with the pressure release of tested mechanical rapping apparatus air intake opening 26, the rapping topworks of tested mechanical rapping apparatus 20-tested mechanical rapping apparatus piston rod 29,30 of tested mechanical rapping apparatus drop bars can break away from tested mechanical rapping apparatus piston waveguide tube 21 under the effect of this pressure reduction, cause the damage of tested mechanical rapping apparatus 20, so pipeline V15 can realize tested mechanical rapping apparatus 20 is carried out non-destructive sealing test (step 41);
After cylindrical shell 11 to be tested, pipeline IV14 finished pressure release, the mechanical rapping apparatus 20 of test was finished in dismounting, installs next tested mechanical rapping apparatus; Slowly Open valve I2, valve III9, valve IV10 close other valves, repeating step 32 ~ 42; Specifically, the present invention has introduced balance branch road-pipeline V15, also can the warranty test cylindrical shell when making in the step 41 not by the outside pressure release of surge tank 4 and the synchronous pressure release of tested mechanical rapping apparatus air intake opening 26, gases in the surge tank 4 and extraneous circulation have been cut off in the step 41 during pressure release, make that the gas that has reached pre-provisioning request pressure and temperature in the surge tank 4 obtains keeping, can avoid during repeating step 32 repeating again heating for a long time process of pressurization, effectively save experimentation cost and test period, improve test efficiency (step 42).
