Centrifugal impeller centrifugal pump impeller is a key component. (1) according to their mechanical structure can be divided into closed, semi-closed and open three. Closed impeller for conveying the cleaning liquid; semi-closed and open impeller for conveying suspension containing solid particles, low efficiency of such pumps. Closed and semi-closed impeller during operation, a portion of the high pressure fluid leaving the impeller can leak into the cavity between the impeller and the pump casing, the impeller due to the suction inlet of the front side of the liquid pressure is low, so that the liquid acts on the front wheel, rear pressure side of the range, they had a point to the inlet side of the impeller axial thrust. The force pushing the inlet side of the impeller to move, causing the impeller and casing wear at the contact, resulting in severe vibration of the pump, D25-30X8 coal mine pump wear, damage to the normal operation of the pump. In the impeller rear panel drill several holes, it can reduce the pressure on both sides of impeller poor, thereby reducing the adverse effects of axial thrust, but also reduces the efficiency of the pump. These holes are called balance hole. (2) by pipette in different ways can be divided into single-suction impeller and double suction two, D12-25X11 coal mine pump wear, simple single-suction impeller structure, fluid can only be sucked in from the side. Double suction impeller impeller symmetrically from both sides simultaneously sucked liquid, D25-30X6 coal mine pump wear, which not only has a large liquid absorption capacity, and essentially eliminate axial thrust. (3) According to the geometry of the impeller blades, coal pump wear can be divided into backward curved blade, radial and bending forward three, since the rear curved blades in favor of converting the kinetic energy of the liquid static pressure energy, and therefore is widely used.
