Major parts of the slurry pump is introduced

mortar pump main components impeller, pump shell and the shaft seal device.

open impeller impeller in blade on both sides of the cover plate, suitable for conveying materials containing relatively large amounts of suspended solids, low efficiency, rarely used.
half closed on the suction side of impeller cover plate, and on the other side has a flat, suitable for conveying easy precipitation or materials containing particles, and a low efficiency;
closed impeller blade on both sides of the plate before and after, high efficiency and is suitable for conveying liquid contains no impurities.
closed impeller has a single suction and double suction in two ways.

function is to pump shell impeller sealing in a certain space, so that the role of the impeller suction and pressure of liquid. Pump shell into a spiral shape, it is also called the volute. , because of the port area gradually expanded from the impeller around the high-speed liquid gradually reduce the flow velocity, the part of the kinetic energy is converted to static pressure can effectively. Not only collected by the impeller pump shell out liquid, but it is also an energy conversion device.

shaft sealing device is used to prevent the liquid in the pump shell leakage along the axis or outside air leakage into the pump housing.
common shaft seal device has two kinds of packing seal and mechanical seal.
filler in general use oiled or coated with graphite asbestos rope.
mainly mounted on the shaft mechanical seal ring and fixed on the pump casing between static ring end face seal for relative motion and to achieve
