Background
The main working components of the slurry pump are an impeller and a shell, and an impeller device in the shell is positioned on a shaft and is connected with a motor to form a whole. When the motor drives the impeller to rotate, the blades of the impeller force the slurry to rotate, namely the impeller does work on the slurry along the movement direction of the slurry, so that the pressure potential energy and the kinetic energy of the slurry are forced to be increased. The slurry flows from the center of the impeller to the outer edge, and a certain vacuum is formed in the center of the impeller, so that the slurry is continuously pressed into the impeller due to the fact that the pressure above the liquid level of the storage tank is higher than the pressure at the inlet of the pump. The slurry is reduced in the internal peripheral speed of the overflow part, so that the pressure in the cavity is increased, external pressure flushing water is supplied into the cavity, solid particles are prevented from entering the inlet seal of the impeller and the packing seal, and further the abrasion of the sealing element is prevented, but the external pressure flushing water is too high in cost, and a small amount of flushing water is easily dropped at the positions of a water seal joint, a water seal ring and the like, so that the slurry is not applicable to occasions with high environmental requirements. In order to prevent the vacuum damage and the interruption of water absorption caused by air leakage at the suction end, the shaft seal type of the traditional slurry pump usually adopts a packing seal, and the sealing structure is easy to cause the leakage of shaft seal water and has poor sealing effect.
