[0002] Processing equipment is typically equipped with a cooling system to cool the workpiece, tools, and equipment within the processing area to maintain machining accuracy and extend the life of the cutting tools. The equipment is equipped with a coolant circulation pump station. The coolant on the equipment is collected at the pump station and filtered and deslagging.

[0026] like Figures 1 to 5As shown, the utility model discloses a coolant circulation pump station, which includes a housing 10, a filter assembly 30 installed on the housing 10, a pumping assembly 40, an output assembly 20 and a control assembly 60. The control assembly 60 is electrically connected to the pumping assembly 40 and the output assembly 20, and the pumping assembly 40 is connected to the filter assembly 30. The housing 10 is a box-type structure, and the internal space can accommodate other components. The pumping assembly 40 adopts a motor and water pump structure to realize the transportation of coolant in the pipeline. It is worth mentioning that the coolant circulation pump station is not limited to the pumping and transportation of coolant, and other liquid fluids can also be pumped and transported using the pump station.

[0027] The output assembly 20 includes a diverter block 21, a pressure stabilizing mechanism 23 installed on the diverter block 21, a plurality of output connectors 24 and a control valve 22. Each control valve 22 controls one output connector 24. The diverter block 21 is provided with a main channel 211 and a plurality of branch channels 212 connected to the main channel 211. Each branch channel 212 is connected to an output connector 24. The main channel 211 and the plurality of branch channels 212 form a main-branch structure. Each branch channel 212 is independently controlled to achieve one or more outputs. The aperture of the main channel 211 is larger than the aperture of the branch channel 212 to provide stable pressure and flow. The diverter block 21 is installed with a plurality of control valves 22 so that each output connector 24 can be independently controlled, thereby improving the controllability of each output.

[0028] The pressure stabilizing mechanism 23 is connected to the main channel 211. The pressure stabilizing mechanism 23 is provided with a reflux channel 26. The reflux channel 26 is connected to the filter component 30. When the pressure in the main channel 211 exceeds a preset threshold, the pressure stabilizing mechanism 23 is connected to the filter component 30. The filter component 30 is used to connect to an external device.

[0029] The pressure stabilizing mechanism 23 is used to maintain a stable pressure in the main channel 211, thereby stabilizing the pressure output by each output connector 24. When the pressure in the main channel 211 is too high, the pressure stabilizing mechanism 23 releases the pressure and guides the coolant in the main channel 211 to flow out, thereby maintaining a stable pressure in the main channel 211.

[0030] The pressure-stabilizing mechanism 23 stabilizes the pressure within the main channel 211 and, when it exceeds a preset threshold, opens to return excess coolant within the main channel 211 to the filter assembly 30.

The control assembly 60 controls each solenoid valve independently to switch on and off, thereby achieving on-off control of the output connector 24. The control assembly 60 controls the coolant circulation pump station and the equipment in conjunction to ensure the corresponding directional output of coolant.
