1)YZ Model Submersible Slurry Pump is a vertical but only suction cantilever centrifugal pump structure. The impeller is a semi-opened vane, and stirring blades are provided at the extension of the suction side of the impeller.
YZ pump is a single counter-level, single suction cantilever structure, with bearing seat, supporting seat, connecting pipe connected hydraulic parts of the pump, the liquid is discharged from the liquid pipe components, the impeller of the pump is a semi-opened impeller, impeller blade inlet extension is provided with mixing blades, the main characteristics of the pump is in the liquid part of the pump shaft, there is enough stiffness, impeller, pump shell between the bearing, do not use shaft seal, A medium containing a larger concentration of fixed particles can be transported. The length of the pump under the liquid insertion is between 800-2000, with suction pipe if necessary. The shaft seal uses a larger pump inserted into the liquid operation, without shaft seal, transmission by a vertical motor installed on the motor support and support seat, with a coupling connected to the pump.

The distribution of solid particles in the pipe (generally referred to as horizontal pipe) becomes more and more uneven as the average velocity of slurry decreases. When the velocity decreases to a certain value, a fixed or sliding bed surface appears at the bottom of the pipe. The velocity at which the particles begin to form a bed is called the sedimentation velocity. Since water is the commonly used transport fluid, it is usually turbulent under normal pipe flow conditions, so the flow mode of heterogeneous suspension under silting velocity is almost turbulent. It is directly related to the settling velocity of particles and the turbulence degree of the system, so it increases with the increase of particle size, particle mass and solid content. The importance of siltation velocity to pipe flow is obvious and it is the lower limit for safe operation. If the flow rate is lower than the silting rate, a bed of solid particles will form in the pipe, resulting in increased friction loss and often pulsating, and even blockage of the pipe. In order to ensure the normal flow of slurry in the pipeline, the velocity must exceed a given minimum value, which is called the critical settling velocity. Generally, the critical settling velocity is greater than the sedimentation velocity.
