Abstract
The utility model provides a marine lifting axial flow pump which comprises a coupler, a pump shaft, a water outgoing elbow, a connecting pipe, a guide vane body, impellers, guide vanes and a water incoming horn pipe. Runners among blades of the guide vane are diffusive, a motor support is arranged at the upper end of the water outgoing elbow, and anticorrosion layers are arranged on inner and outer sides of the connecting pipe, the water outgoing elbow and the water incoming horn pipe. Flow of the marine lifting axial flow pump is dozens of times that of common submersible pumps, and the marine lifting axial flow pump is low in lift, so that lifting requirements of a ship can be quickly met; a pump body and other parts are all provided with the anticorrosion coatings, thereby being durable, corrosion-resistant and free of corrosion, liquid containing particles and oil can be pumped, and output flow is stable; the internal impellers are in central symmetry, so that pulsation hardly occurs. During working, the marine lifting axial flow pump is needless of manual water adding and guiding, extremely low in noise, high in efficiency, stable in operation, simple in structure and convenient to mount.
Description
Technical field
The utility model relates to axial-flow pump, especially relates to a kind of lifting axial-flow pump peculiar to vessel.
Background technique
Axial-flow pump is a kind of high-specific rotation speed water pump, because flow is large, the characteristics such as lift is low, be widely used in some departments.Aspect farmland discharging-irrigating, the irrigation in fritter field adopts the removable miniature axial-flow pump; Adopt big-and-middle-sized axial-flow pump controlling flood and draining flooded fields; Adopt Large Axial Flow Pump aspect water conservancy construction, distruting water transregionally; Other advance draining as large-scale iron and steel enterprise water use, dock, and the propelling of shallow draft ship also adopts axial-flow pump usually.
The discharge of present steamer biloge water or wheel cabin bottom water are pressed general diaphragm pump or the reciprocating pump that adopts the transmission of eccentric wheel mode, in use, need to add water to manual in diaphragm pump or reciprocating pump, and diaphragm pump or reciprocating pump can not be taken out the sewage of particle; During work, noise ratio is larger, also is easy to " pulsation " phenomenon.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of lifting axial-flow pump peculiar to vessel, produces the phenomenon of " pulsation " in the time of can effectively solving work, and the output output flow is stable, and lift is low, and noise is little.
For achieving the above object, the utility model proposes a kind of lifting axial-flow pump peculiar to vessel is provided, comprise coupling, pump shaft, Discharging bent-tube, connecting tube, diffuser, impeller, stator and water-inlet horn pipe, described connecting tube upper end is connected with Discharging bent-tube, described connecting tube lower end is connected with diffuser, described diffuser lower end is connected with the water-inlet horn pipe, described Discharging bent-tube upper end is provided with coupling, described coupling bottom is connected with pump shaft, be provided with stator and impeller in described diffuser, institute's stator of telling and impeller are connected on pump shaft, described impeller is with respect to the pump spindle center symmetry, the interlobate runner of described stator is divergent contour, described water outlet upper end is provided with electric machine support, described connecting tube, the interior outside of Discharging bent-tube and water-inlet horn pipe is provided with anti-corrosion layer.
As preferably, be provided with emergency support outside described connecting tube, the convenient installation with fixing.
As preferably, the bearing in described coupling adopts high-grade ball bearing, increases water displacement and drainage efficiency.
Flow of the present utility model be tens times of common submersible pump flow and also lift low, can meet rapidly the lifting requirement of ship, the pump housing and remaining part are all through being provided with corrosion-resistant finishes, durable wear, do not corrode, can take out the liquid that contains particle and oil content, output flow is stable: internal impeller belongs to Central Symmetry, and " pulsation " phenomenon does not almost have.During work, do not need to add diversion by hand, noise is extremely low, and efficiency is high, stable, simple in structure, easy for installation.
