[0002] A slurry pump is a type of pump equipment specially used to transport slurries containing abrasive solid particles. They are widely used in mining, electric power, metallurgy, coal, environmental protection and other industries. The working principle of a slurry pump is based on centrifugal force. The slurry is sucked in and accelerated from the suction end through the rotation of the impeller, and then the kinetic energy is converted into static pressure energy through the volute pump casing and transported to the discharge pipe at a higher pressure.

[0003] In order to reduce the possibility of slurry blockage at the discharge end of the slurry pump, an auger is usually set at the discharge end of the slurry pump to transport the slurry at the discharge end of the slurry pump, and an extension pipe is set on the opposite side of the discharge end, and a motor for driving the auger is installed at the end of the extension pipe.

[0004] However, since the slurry pump transports the slurry through pressure, the slurry at the discharge end and inside the extension pipe will have a certain pressure, and the liquid in the slurry will seep into the interior of the motor from the connection between the auger and the motor shaft end, causing damage to the motor and reducing the service life of the motor.
