[0044] Turn on the pump control mechanism 6, the motor 9 rotates, drives the plunger pump 7 through the coupling, opens the valve of the water tank 8, and water is sucked into the plunger pump 7 after passing through the purifier 20. When the plunger pump 7 is working normally, adjust the pressure of the pressure regulating valve 10 to the minimum (loosest) position, and adjust the safety pressure of the safety valve 11 normally (maximum). At this time, water sprays out from the water jet nozzle, and a large amount of water flows out of the outlet of the pressure regulating valve 10. The plunger pump 7 operates normally and makes normal sound. Turn the switch of the pressure regulating valve 10 and slowly increase the pressure regulating valve 10, observe the change of the reading of the pressure gauge 12, and be ready to turn off the power at any time when the operation sound of the plunger pump 7 is abnormal or the reading of the ammeter is abnormal. The normal maximum current reading is 15 A, and the maximum reading of the pressure gauge 12 is 35 MPa. When it exceeds, relieve the pressure through the safety valve 11; Turn on the water jet control mechanism 13, the programmable controller of the two axes drives the driver and its stepping motor to achieve two-dimensional interpolation motion, and can perform diversified controls such as acceleration and deceleration, drive the single-axis stepping motor, and achieve the motion in the z direction parallel to the cutting water jet. By moving the water jet nozzle in the three-axis directions of front-back, left-right, and up-down, the unvulcanized rubber and vulcanized rubber are cut and sampled.
