And the rotary joint 7 detects that the workpiece is installed, and then the pressing detection work is started.
Step two, as shown in fig. 1 to 8, when the interior of the rotary joint 7 is pressurized, the control cabinet 5 starts the pressurizing water pump 6, the pressurizing water pump 6 starts to work to absorb water from the interior of the water tank 2, the water in the interior of the water tank 2 is sucked through the water inlet pipe 602 and is discharged through the water outlet pipe 603, when the water discharged through the water outlet pipe 603 flows to the position of the tee 604, the electromagnetic valve 606 is in a closed state, so that the water flow continues to advance along the water outlet pipe 603, the water flow flows into the transverse groove 814 through the water outlet pipe 603, and the transverse groove 814 is communicated with the vertical groove 813, so that the water flow flows into the interior of the rotary joint 7 through the transverse groove 814, the vertical groove 813 and the; air can exist in the pipeline in the pressurizing process, the main shaft 805 and the whole detection device are vertically designed, and the exhaust valve 818 is installed at the top of the through hole 815, so when the pressurizing water pump 6 works, water flow can move upwards through the air in the pipeline, the air in the pipeline can be exhausted through the exhaust valve 818 above the main shaft 805, the water flow can flow into the through groove 811 of the main shaft 805 through the rotary joint 7 in the pressurizing process until the through groove 811 is filled with water, no air exists in the whole pipeline system, and the influence of the air on the water pressure detection value can be prevented; so when detecting rotary joint 7, its work piece vertical setting, the inside bubble is automatic to rise and is discharged through discharge valve 818 when suppressing the water injection, can prevent to have the inside air influence to look at the experimental result when suppressing.
When the pipeline system is filled with water, the water pump 6 is pressed to continue working, when the pressure reaches a certain pressure value in the future, the water pump 6 is pressed to automatically stop working (the maximum working pressure of the water pump 6 is adjusted to be the detection standard pressure in the early stage), and when the water pump 6 stops working, the controller in the control cabinet 5 automatically records the time t1 and the pressure p 1.
And step three, referring to fig. 1 to 8, when the pressurizing water pump 6 stops working, the speed reducing motor 3 starts working, the speed reducing motor 3 rotates to drive the driving pulley 301 to rotate together, so that the belt 4 drives the driven pulley 808 to rotate together, and the driven pulley 808 is in key connection with the second partition 807 on the main shaft 805, so that the driven pulley 808 can drive the upper component of the rotary joint 7 to rotate together through the main shaft 805, and the rotary joint 7 can be driven to rotate by the speed reducing motor 3 to simulate the rotary water supply action of the rotary joint 7.
When the time is rotated for the time of min (the time can be adjusted by the controller in the control cabinet 5), the controller in the control cabinet 5 records the time t2 and the pressure p2 again; therefore, p1-p2 are the pressure change values in the time period from t1 to t2, and whether the rotary joint 7 is qualified or not can be judged according to the pressure change values.
To sum up, the design of detection device 8 is suppressed to the rotation, suppress to the inside water injection of rotary joint through suppressing water pump 6, when its pressure reachs certain numerical value, suppress water pump 6 automatic stop, it is rotatory to drive rotary joint 7 through gear motor 3, can simulate the 7 rotatory water supply actions of rotary joint, survey manometer 601 numerical value after motor simulation certain time, through the comparison of front and back pressure numerical value, the pressurize effect of detectable rotary joint 7 during operation, judge whether rotary joint 7 is qualified according to its numerical value, thereby improved rotary joint 7 and restoreed the qualification rate, it leaks the incident and takes place to reduce the conticaster bale restoration cost to reduce to go up the line.
Step four, combining with the data recorded by the controller in fig. 1-8, after the controller records the data for the second time, the speed reducing motor 3 stops working, and the rotary joint 7 is still; at this time, under the control of the control cabinet 5, the electromagnetic valve 606 is automatically opened, because the interior of the water outlet pipe 603, the interior of the rotary joint 7 and the interior of the through hole 815 are communicated, and the pressure in the pipeline is high, when the electromagnetic valve 606 is opened, the water in the interior flows out through the pressure relief pipe 605, and the flowing water returns to the water tank 2; therefore, the middle part of the water outlet pipe 603 is provided with a tee 604; the other end of the tee 604 is provided with a pressure relief pipe 605; the middle part of the pressure relief pipe 605 is provided with an electromagnetic valve 606; the bottom of the pressure relief pipe 605 is arranged in the water tank 2, after the rotary joint 7 is detected, the pressure relief action can be realized through the control of the electromagnetic valve 606, and the rotary joint 7 can be detached under the normal pressure state; during the detection, water is absorbed from the inside of the water tank 2, and after the detection is finished, the water flows back to the water tank 2, so that a loop is formed, the circulating pressurization detection work is realized, and water supplement to the inside of the water tank 2 is basically not needed.
When the electromagnetic valve 606 is opened for 5 seconds, the electromagnetic valve 606 is rotated and closed; the whole pipeline system is in a normal pressure state, at this time, the bolts 804 on the fixed seat 701 at the bottom of the rotary joint 7 and the bolts 804 on the flange 705 at the top are loosened, the rotary joint 7 can be detached from the base 801, and the detection of the rotary joint 7 is finished once.
