Description
Technical field
The present invention and a kind of long-shaft pump, particularly relate to long-shaft pump under a kind of combined vertical solution, belong to electromechanical equipment technical field.
Background technique
Under current existing spatial guide blade formula liquid in long-shaft pump, there is two profiles formula: a kind of is guide bearing structure pattern, and another kind is rolling bearing structure pattern.Long-shaft pump under the spatial guide blade formula liquid of guide bearing structure pattern, is provided with guide bearing and carries out radial fit location, bear the radial force of water pump between pump shaft and spatial guide blade.Pillar coordinates with spatial guide blade and connects, and pump shaft connects with transmission shaft case butt coupling, is placed in pillar and (does not have pillar to be then directly placed in connecting tube), pump medium contact with water pump.Connecting tube arranges bearing support, arranges guide bearing in bearing support, guide bearing and transmission shaft carry out radial fit location, play guide-localization effect.This guide bearing adopts rubber material or composite to make, water pump is very high at running medium speed, usually make guide bearing because of sliding friction serious wear, again because of guide bearing and pump shaft, transmission shaft and pump physical contact between media, lift is as easy as rolling off a log enters guide bearing along with the High Rotation Speed of axle produces for the impurity that medium includes, and makes guide bearing and axle serious wear.Water pump must arrange cooling liquid water pipe, injects cooling liquid and lubricates, lowers the temperature and rinse, thus cause environment unhygienic, waste water resource when water pump operation to guide bearing.Due to the structural limitations of long-shaft pump under the spatial guide blade formula liquid of this structural type, weight and the axial force of the whole rotor part of water pump are all born by the thrust-bearing above pump holder or motor, the cantilever of the axle of water pump is very long, guide bearing and axle easily wear and tear again, matching gap increases, the vibration values of water pump operation increases, thus causes the very fast damage of thrust-bearing or motor.Because the vibration values of this structure water pump increases, the cantilever of the axle of water pump is very long, and therefore the shaft seal of water pump can not adopt mechanical seal, can only adopt packing seal, so the medium that water pump is pumped can leak, affects environment.Water pump because of this structure adopts case butt coupling to carry out spindle, and the concentricity of the axle of water pump is difficult to be guaranteed, and the operational shock value that can strengthen water pump increases, and also can bring the installation, maintenance inconvenience extremely of water pump simultaneously, increase installation and maintenance cost.Axle because of this structure water pump directly contacts with medium and easily corrodes, and water pump is when pumping Korrosionsmedium, and what the axle of water pump all adopted is all stainless steel, causes the manufacture cost of water pump too high.Due to the above-mentioned reason of this structure water pump, cause that the Security of water pump is not high, working life is long, lift is not high, the degree of depth is not long under liquid.
Long-shaft pump under the spatial guide blade formula liquid of rolling bearing structure pattern, at spatial guide blade, between pillar and connecting tube, be provided with rolling bearing assembly, this rolling bearing assembly and spatial guide blade upper end adopt seal with O ring to coordinate, rolling bearing bottom is provided with outside framework oil seal, and rolling bearing assembly and lower end, spatial guide blade cooperation place are provided with outside framework oil seal and black box.This kind of bearing unit is placed in spatial guide blade upper end, adds the jib-length of pump shaft between impeller and bearing, reduces the stiffness of pump shaft.When in the process of water pump at high speed operation, the swing of impeller and pump shaft is very large, thus causes the damage of rolling bearing assembly, affect the normal use of water pump, the working life of reduction water pump.Occur because water pump O shape circle and black box in long-term using process have failure phenomenon, this medium that water pump can be caused to pump enters in rolling bearing assembly, and the working environment destroying rolling bearing damages bearing; Add on bearing unit and exhaust port is not set, during water pump operation, the heat that black box and bearing produce can make the air in pillar expand, pillar cannot be discharged, thus increase the weight of to affect the sealability of water pump and the working life of bearing, affect the normal use of water pump, reduce the working life of water pump, increase the maintenance cost of water pump.Because there being the impact of above reason, make that the degree of depth under the liquid of water pump falls short of, lift is not high enough.
At present under the spatial guide blade formula liquid of existing two kinds of structural types in long-shaft pump, owing to being all directly adopt spatial guide blade to be combined to form pump chamber, because the axial dimension of spatial guide blade is long, so the pump shaft of water pump is long and affect machining accuracy, waste raw material; Water pump spindle is all adopt impeller balance hole to balance to equilibrium of forces, and the phenomenon if equalizing orifice is blocked, then cause axial force balance poor effect, and for making water pump axial force fully be balanced, impeller balance hole design is very large, thus reduces the efficiency of water pump.Therefore the quantity of water pump vane assembling is restricted, and affects water lift of pump.
