[Asia Pump Network News] mortar pump is a slurry pump, it has a wear-resistant, anti-corrosion characteristics. The main components of the mortar pump impeller, pump housing and shaft seal device, then we understand that it is the structure of these major components is what? If you do not understand, the following is the main components of mortar pump structure introduced. The main components of mortar pump structure 1, the impeller can be based on different leaf cover, divided into open impeller, semi-closed impeller, closed impeller three. Open impeller on both sides of the blade without cover, suitable for conveying material containing a large amount of suspended solids, low efficiency, rarely used; semi-closed impeller in the suction side of the cover without cover, and on the other side cover , Suitable for conveying easily sediment or pellet containing materials, the efficiency is also lower; the closed impeller has front and back covers on both sides of the blade and is suitable for conveying liquids without impurities. It has single suction and double suction. 2, pump shell Its role is to seal the impeller in a certain space, so that the role of impeller suction and out of the liquid. Pump casing made of spiral shape, it is also known as the volute. Due to the gradual enlargement of the cross-sectional area of ​​the flow passage, the high-speed liquid thrown out from the impeller gradually reduces the flow velocity and effectively converts part of the kinetic energy into static pressure energy. Pump housing not only brings together the liquid thrown by the impeller, but also an energy conversion device. 3, shaft seal device The role of shaft seal device is to prevent liquid leakage within the pump casing along the shaft or outside air leakage into the pump housing. Commonly used shaft seal packing packing and mechanical seal are two kinds of packing seal generally with oil or graphite coated asbestos rope, and the mechanical seal is mainly by the shaft mounted on the fixed ring and the stationary ring in the pump casing Between the end face for relative movement to achieve the purpose of sealing.
