単になる。Furthermore, according to the second feature, the centrifugal separation chamber and the pump chamber are located on the same rotation axis but are separate rooms, so the separation effect in the centrifugal separation chamber is adversely affected by the components necessary for pump operation. This will not cause any adverse effects. If the centrifugation chamber also serves as a pump chamber, the components necessary for the pump operation will agitate the oil to be centrifuged, reducing the centrifugal action. Of course, the fact that the centrifugal separation chamber and the pump chamber are on the same rotational axis means that the centrifugal force from the centrifugal motor can be easily applied to the pump chamber, making the configuration of the device extremely simple. become.

清浄化される。Now, when the rotational drive source 11 is started to drive and untreated oil begins to be introduced through the introduction pipe 20, the centrifugal separation chamber 13 and the pump chamber 14 rotate, and the introduced oil is thereby subjected to centrifugal force. receive. This centrifugal force separates the crude contaminants from the oil in the centrifugal separation chamber 13. As oil is continuously introduced into the centrifugal separation chamber 13, the liquid level increases, and the centrifuged oil sequentially enters the pump chamber 14 through the opening 14b. The oil that has entered the pump chamber 14 continues to be subjected to a large centrifugal force, and the further outward it goes, the greater the pressure is generated. Due to this high pressure, the oil in the pump chamber 14 is pushed out from the suction port 41 into the oil transport pipe 40 and is carried to the filter 4. The oil conveyed to the filter 4 is filtered there from fine contaminants that have not been centrifuged. This cleans the oil.

ることができる。If the rotation speed of the centrifugal separator 10 is constant, the hydraulic pressure near the oil transport pipe suction port 41 in the pump chamber 14 is also approximately constant, and a special pressure regulating valve is not required to adjust the transport pressure. do not. When the filter 4 becomes clogged and the amount of filtered oil decreases, the liquid level in the pump chamber 14 will increase.
Oil will eventually overflow from the pump chamber 14, but by providing an overflow flow rate sensor in the recovery pipe 30, it is possible to easily know when it is time for maintenance of the filter 4.
