At this time, the controller controls the unloading valve 20 to be electrically closed, and the first reel control valve 12 to be electrically opened. The controller outputs a certain current value to enable the hydraulic pump 19 to reach a certain displacement, the hydraulic motor 21 reaches a certain motor rotating speed, and the high-pressure water pump 8 is further controlled to reach a certain water pump rotating speed, so that high-pressure water with a certain water pump pressure is output. The set pressure representing the target water pump pressure set by the controller is slightly lower than the preset value of the first pressure regulating valve 11. The real-time water pump pressure at the outlet of the high-pressure water pump 8 is detected by the pressure sensor 9, the real-time water pump pressure is compared with the set pressure, and if the real-time water pump pressure is lower than or higher than the set pressure, the hydraulic pump displacement of the hydraulic pump 19 is controlled to correspondingly change, so that the water pump pressure of the high-pressure water pump 8 can be always maintained at a stable value, and the overflow condition of the first pressure regulating valve 11 does not exist.
When the nondestructive excavation is carried out, the spray gun is connected to the outlet of the hose of the second reel 18, the nondestructive excavation is pressed down, the unloading valve 20 is closed, the electromagnetic directional valve 13 is opened, the second switching control valve 14 is switched in an electric mode, the target pressure value set by the controller is slightly smaller than the preset pressure value of the second pressure regulating valve 16, and the water pressure regulating process is similar to the regulating process when the pipeline dirt is cleaned.
When the cleaning operation is performed, the spray gun is connected to the outlet of the hose of the second reel 18, and the cleaning button is pressed. At this time, the unloading valve 20 is electrically closed, the second reel control valve 13 is electrically opened, and the water pressure adjusting process is similar to the adjusting process when the pipeline is cleaned of dirt. In the high-pressure waterway system of the embodiment, the second reel 18 is shared by the nondestructive excavation and cleaning operations, and the function switching is realized by switching the second switching control valve 14, so that the operation is simple and easy.
When the pipeline is operated for draining, a drainage button is pressed. At this time, the drain valve 4 is electrically opened, and the clean water in the pipe between the water tank 1 and the high-pressure water pump 8 is discharged through the drain valve 4 due to the action of gravity. After a certain delay, the drain valve 4 is closed, the air storage tank control valve 6 is electrically opened, the first reel control valve 12 is electrically opened, and the clean water in the hose and the corresponding branch of the first reel 15 is discharged. The first reel control valve 12 is powered off and closed after a certain time delay, the second reel control valve 13 is powered on, the clean water in the branch circuit of the second pressure regulating valve 16 is set for discharging, the second switching control valve 14 is powered on and commutated after a certain time delay, the clean water in the hose and the connecting branch circuit of the second reel 18 is discharged, and the water discharging button is closed after water discharging is completed.
