When water is discharged from the centrifuge, the discharge speed is affected by the installation position of the multi-way connecting pipe 1 and the suction pipe 2. When the multi-way connecting pipe 1 and the suction pipe 2 are installed at a higher position, the flow rate is slower. At this time, the second control valve 202 near the multi-way connecting pipe 1 is opened. Under negative pressure, the water is quickly drawn into the intermediate pipe 201, accelerating the discharge of water from the centrifuge and improving the drainage efficiency.

At this time, the vacuum pump 203 is started to vent the air in the vacuum section, forming a negative pressure inside. When water is discharged from the centrifuge, the water discharge speed will be affected by the installation position of the multi-directional connecting pipe 1 and the suction pipe 2. When the installation position of the multi-directional connecting pipe 1 and the suction pipe 2 is higher, the flow rate is slower. At this time, the second control valve 202 near the multi-directional connecting pipe 1 is opened, and under the negative pressure state, the water flow is quickly sucked into the intermediate pipe 201. In the process, the centrifuge accelerates the discharge of water, improving drainage efficiency. Then, another second control valve 202 is opened to allow water to drain into the discharge pipe 3. The multi-directional connecting pipe 1, including the cross-shaped four-way multi-directional pipe 101, allows the installation direction of the suction pipe 2 to be selected according to the connection situation. After the installation position of the suction pipe 2 is determined, the first control valve 104 is controlled to close the other two discharge branch pipes of the multi-directional pipe 101, providing users with convenient multi-directional connection options according to the installation environment. The discharge pipe 3, including the plastic telescopic flexible hose 302, allows users to easily adjust the position of the discharge end of the drain pipe and connect it to drainage mechanisms such as sewers.
