[0044] The part high-pressure flushing operation step, the worker pushes the flushing jig main body 1 and moves it to the placement position of the parts to be flushed by using the universal wheels at the bottom, places the parts to be flushed between the two cavities of the flushing jig main body 1, starts the high-pressure pump, and the high-pressure pump delivers liquid and sand suction through the connecting pipe 2 and the connecting sleeve 101 to the inside of the cavity, and the cavity discharges the liquid and sand suction outward to flush the parts, and during the flushing process, the flushing time and pressure can be adjusted according to the actual situation;

[0045] After the flushing is completed, the high-pressure pump is stopped, the pressing frame 304 is pushed in the reverse direction with both hands to overcome the locking force of the locking block 308 and make the pressing frame 304 turn outward, at this time the locking rod 306 is relaxed, the connecting pipe 2 is taken off from the connecting sleeve 101, and the separation of the connecting pipe 2 and the connecting sleeve 101 is completed;

[0046] The main difference between the second embodiment and the first embodiment is that the high-pressure flushing structure of the flushing tool body 1 is based on the prior art, and the installation of the high-pressure pump on the connecting pipe 2 and the operation of the fine sand and water tank are also based on the prior art. Therefore, the use steps of the second embodiment are more focused on the operation of the prior art part based on the first embodiment.

[0047] Based on the preparation and installation of the connecting device 3 in the first embodiment, further check the selected high-pressure flushing structure of the prior art to ensure that all parts are intact. According to the installation method of the prior art, add the high-pressure flushing structure on the basis of the cavity and the connecting pipe 2, ensure firm installation, and good sealing of each connection part.

[0048] High-pressure pump installation and debugging steps: the staff installs an existing high-pressure pump on the connecting pipe 2, strictly according to the installation instructions of the high-pressure pump to ensure correct installation position and tight connection of each connection interface. After installation, debug the high-pressure pump to check if it is running normally and the pressure output meets the requirements.

[0049] Fine sand and water tank setting steps: the staff also refers to the prior art to set fine sand and water tank based on the high-pressure pump, to ensure that the amount of fine sand added meets the flushing requirements, the amount of water in the water tank is sufficient, and the fine sand and water supply system is running normally and can be smoothly transported to the high-pressure pump for flushing work.
