FLUID DELIVERY DEVICE

摘要

A fluid delivery device, comprising an integrated cabinet (41), a pump (42) installed in the integrated cabinet (41), an inlet pipeline (43) connected to the pump (42), and an outlet pipeline (44) connected to the pump (42); the pump (42) comprises a motor (421) located at the bottom portion of the integrated cabinet (41), a pump head (422) located at the top portion of the integrated cabinet (41), and a magnetic coupling portion (423) located between the motor (421) and the pump head (422); the pump head (422), the magnetic coupling portion (423) and the motor (421) are arranged in a sequence from top to bottom; and the pump head (422) is provided with a U-shaped flow channel and a gear mechanism (4222) therein located at the bottommost portion of the flow channel. The fluid delivery device eliminates bubbles in the solution accumulated in the pump, thus ensuring a working efficiency of fluid delivery of the pump, and ensuring precise control of a delivery amount.
