[0032] An operating table 2 is mounted on the surface of the mounting bracket 1.

[0033] A water tank 9 is installed inside the mounting frame 1.

[0034] The surface of the operating table 2 is equipped with multiple shelves 3.

[0035] The No. 8 vertical multistage centrifugal pump is a Southern Pump CDM5-17 series light-duty vertical multistage centrifugal pump. Its main structure includes an impeller, pump casing, and mechanical seal (CDLA-12 / WBF14). The impeller outer diameter is 82mm, the rotation speed is 2900rpm, the motor power is 3kW, and the flow rate is 5m³ / h. 3The pump has a flow rate of [number] m / h, a head of 105 m, an efficiency of 70%, and a media temperature range of -15℃ to +70℃ (hot water type can reach +120℃).

[0036] The stainless steel bag filter model 7 is Yuehuahao YH-4# stainless steel bag filter. Its structure includes a filter housing and a filter bag. The working pressure is 0.2-1.0MPa, the flow rate is 5-10m3 / H, and the accuracy is 20μm. There are four such filters in total.

[0037] The frequency converter 5 is used to monitor and regulate the cleaning pressure, keeping it at 7 kgf.

[0038] The electrical control system 4 is the core of the equipment's control system, used to set relevant parameters and control the equipment's start-up and shutdown operations.

[0039] The labeling machine 6 can label the hose after cleaning.

[0040] Water tank 9 is used to store cleaning agents.

[0041] Connection between vertical multistage centrifugal pump 8 and stainless steel bag filter 7: Stainless steel bag filter 7 is connected to vertical multistage centrifugal pump 8 through a pipeline. Vertical multistage centrifugal pump 8 extracts cleaning agent from water tank 9 and transports it through a pipeline to stainless steel bag filter 7 for filtration. The filtered cleaning agent is then transported through a pipeline to a high-pressure hose for circulation rinsing.

[0042] Connection between frequency converter 5 and vertical multistage centrifugal pump 8: Frequency converter 5 is connected to vertical multistage centrifugal pump 8 through electrical circuits to monitor and adjust the operating status of vertical multistage centrifugal pump 8, thereby controlling the cleaning pressure.

[0043] Connection of electrical control system 4 to various components: Electrical control system 4 is connected to vertical multistage centrifugal pump 8, frequency converter 5 and label printer 6 through electrical lines to realize the control of the entire equipment.

[0048] Place the power steering high-pressure hose and other parts to be cleaned on the rack 3 on the operating table 2.

[0049] II. Cleaning Stage

[0050] Press the start switch, and the electrical control system 4 issues a command to start the vertical multistage centrifugal pump 8. The vertical multistage centrifugal pump 8 draws out the cleaning agent from the water tank 9 and delivers the cleaning agent to the stainless steel bag filter 7 through the pipeline.

[0051] The cleaning agent is filtered through a stainless steel bag filter 7 to remove impurities, and then delivered through a pipeline to a high-pressure hose.

[0052] The inverter 5 monitors the cleaning pressure in real time, ensuring it remains at 7 kgf. Under high pressure, the cleaning agent circulates and flushes within the high-pressure hose for 10 seconds. This high-pressure circulation effectively removes particulate and fibrous foreign matter, as well as abrasive particles such as quartz, gravel, corundum, and glass, ensuring the total weight of impurities in the hose is ≤100 mg / m³. 2 It meets the cleanliness requirements.

[0053] III. Conclusion

[0054] After cleaning is complete, the device will light up an OK green light, indicating that cleaning is finished. At this time, the cleaned parts can be taken out from the rack 3, and the labeling machine 6 can label the cleaned hoses for subsequent management and use.

The machine monitors the cleaning pressure in real time through a frequency converter 5 and precisely adjusts the rinsing force to avoid foreign matter residue due to insufficient pressure or damage to the inner wall of the hose due to excessive pressure, thus ensuring the stability of the cleaning effect.

[0057] The vertical multistage centrifugal pump drives the cleaning agent to circulate and rinse within the hose, shortening the rinsing time and significantly reducing operation time compared to traditional cleaning processes, thus improving production efficiency.
