Detailed Description
Referring to fig. 1, the present embodiment provides a phase crossing prevention structure for a three-phase disk separator, which employs a liquid level ring and a small lock ring with overflow holes, so that when a light phase and a heavy phase overflow, the light phase and the heavy phase do not overflow into an opposite pump chamber and are discharged from an overflow port, thereby effectively preventing phase crossing between the light phase and the heavy phase. The device comprises a liquid level ring 2 and a small locking ring 6, wherein the liquid level ring 2 is arranged between a heavy-phase centripetal pump 1 and a light-phase centripetal pump 7, a liquid level ring overflow groove 9 is formed in the liquid level ring 2 along the circumferential direction, a liquid level ring overflow channel 3 is formed in the liquid level ring along the radial direction, the liquid level ring overflow groove 9 is connected with one end of the liquid level ring overflow channel 3, the other end of the liquid level ring overflow channel 3 is connected with a small locking ring overflow groove 5, and the small locking ring overflow groove 5 is connected with a small locking ring overflow channel 4 formed in the small locking ring 6 along the radial direction.
A heavy phase centripetal pump 1 is arranged above the liquid level ring 2, and a heavy phase pump chamber 11 is arranged outside the heavy phase centripetal pump 1.
A light-heavy phase serial phase channel 10 is arranged in the liquid level ring overflow groove 9, when the liquid level is smaller than the light-heavy phase serial phase channel 10, heavy phase liquid enters the liquid level ring overflow groove 9 through the light-heavy phase serial phase channel 10 due to centrifugal force generated by high-speed rotation, then enters the small locking ring overflow groove 5 through the two liquid level ring overflow channels 3 on the liquid level ring 2, and finally is discharged out of the rotary drum through the pair of small locking ring overflow channels 4 on the small locking ring without entering the light phase pump chamber 8.
