Abstract
The utility model relates to a centrifugal mud sand pump for digging and discharging mud and sand. The utility model is composed of an electric motor seat, a pump body, a bearing protective seat, a pump seat, a pump shell, a main shaft, an upper bearing, a lower bearing, an impeller wheel, etc. Compared with the existing common vertical slurry pump, the service life of the bearing is improved, the framework type sealing ring of the interior of the pump seat is conveniently changed, and the utility model is suitable for mud and sand digging and discharging engineering.
Description
The utility model belongs to engineering silt particle excavation mechinery technical field, is specifically related to a kind of centrifugal sand pump that bearing protection seat is arranged.
At present, the vertical slurry pump of the excavation that China generally uses in engineering, cleaning silt particle mainly is made up of motor cabinet, the pump housing, pump seat, pump case, rotary main shaft, metal (upper and impeller etc.The upper and lower bearing of this slurry pump rotary main shaft places respectively within motor cabinet and the pump seat.Because the working environment of pump is in mud, sand or silt particle mixing material, during work, the influence of working pressure in the wearing and tearing of mud, sand particle and the pump in the very short operating time, causes sealing function inefficacy in the pump.Because impeller high speed rotating in pump case, silt particle produces pressure greatly under action of centrifugal force, just can upwards break through skeleton seal ring in the pump seat along main shaft, enters in the lower bearing of main shaft, very fast bearing wear is damaged.Because skeleton seal ring itself is exactly a quick-wear part, need often to change simultaneously, change skeleton seal ring and must dismantle bearing.The slurry pump of frequent dismounting bearing, axle reduces gradually with the quality of fit of bearing.Not only tear open, unload, repair very convenient, but also will influence engineering construction.
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides a kind of and can improve the slurry pump bearing centrifugal sand pump with bearing protection seat in working life.
The purpose of this utility model is achieved in that sand pump mainly is made up of motor cabinet, the pump housing, bearing protection seat, pump seat, pump case, rotary main shaft, metal (upper and impeller etc.Promptly on the basis of the vertical slurry pump that generally uses now, set up a kind of bearing protection seat.Bearing protection seat is installed between the pump housing and the pump seat, and the lower bearing that revolves a main shaft places in the bearing protection seat.Thrower is equipped with in bottom at bearing protection seat inner bearing seal ring, has silt particle on the bearing protection pedestal and throws away mouth.When machinery is opened, after sand pump work a period of time, because centrifugal action, silt particle is arranged when main shaft is upwards crossed the pump seat seal ring, press the silt particle of leaping up up to be thrown away mouth by silt particle and throw away the pump housing by the thrower of high speed rotating.So just avoid silt particle to enter lower bearing, played the effect of protection bearing.When the skeleton seal ring in the pump seat need be changed, needn't dismantle bearing.Repair, disassemble or assemble are very convenient.
Description of drawings:
Accompanying drawing 2 is structural representations of sand pump bearing protection seat.Among the figure, 2-1 is a rotary main shaft, and 2-2 is a bearing protection pedestal, and 2-3 is a thrower, and 2-4 is that silt particle throws away mouth, and 2-5 is skeleton seal ring, and 2-6 is a lower bearing, and 2-7 is a bearing cap.
Embodiment's accompanying drawings of the present utility model is as follows: bearing protection seat is made of bearing protection pedestal 2-2, thrower 2-3, skeleton seal ring 2-5, bearing cap 2-7 etc.Bearing protection pedestal has silt particle and throws away a mouthful 2-4.Bearing protection seat 1-6 is installed between pump housing 1-4 and the pump seat 1-7, and the lower bearing 1-5 of rotary main shaft 1-3 places within the bearing protection seat 1-6.When machine work, rotary main shaft 1-3 rotation, impeller 1-9 rotates, because centrifugal action forms big pressure in the pump case 1-8, the part silt particle will move upward along main shaft 1-3.After silt particle is crossed the skeleton seal ring 1-11 of pump seat, just silt particle is thrown away a mouthful 1-12 by silt particle with the thrower 1-13 of rotary main shaft 1-3 high speed rotating and throw away the pump housing.Thereby avoided silt particle to enter lower bearing 1-5, played the effect of protection bearing.
The utility model is owing to designed bearing protection base device; present vertical mud, silt particle, the sewage pump that generally uses; can greatly improve the working life of bearing, and pump seat in-seam frame type sealing ring damages when repair the back and need not dismantle bearing, change very convenient.Be highly suitable for digging the use of spoil disposal sand engineering.
