Operating Principle of High-Temperature Thermal Oil PumpThe working principle of the high-temperature thermal oil pump is similar to that of a gear pump, which alters the working volume through gear meshing to convey the melt. The working process includes:

　　1.

·When the thermal oil pump rotates, the melt enters the gear teeth slots of the two gears in the suction cavity.

·As the gears turn, the melt is drawn into the discharge chamber from both sides.

·The re-engagement of the gears pushes the molten material out of the tooth slots into the discharge cavity, ultimately being forced into the outlet pipe.
