Description
Technical field
The present invention and a kind of long-shaft pump relate in particular to long-shaft pump under a kind of combined vertical solution, belong to the electromechanical equipment technical field.
Background technique
In the long-shaft pump, two kinds of patterns are arranged under present existing spatial guide blade formula liquid: a kind of is the guide bearing structure pattern, and another kind is the 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, the radial force of bearing water pump between pump shaft and spatial guide blade.Pillar cooperates connection with spatial guide blade, pump shaft connects with case butt coupling with transmission shaft, and placing in the pillar (does not have pillar then directly to place in the connecting tube), pumps medium with water pump and contacts.In connecting tube bearing support is set, guide bearing is set in the bearing support, guide bearing and transmission shaft carry out the radial fit location, play the guide-localization effect.This guide bearing adopts rubber material or composite to make, water pump is very high at the running medium speed, usually make guide bearing because of the sliding friction serious wear, again because of guide bearing with pump shaft, transmission shaft and pump medium and directly contact, the impurity that medium includes makes guide bearing and axle serious wear along with the High Rotation Speed of axle produces the as easy as rolling off a log guide bearing that enters of lift.Water pump must arrange the cooling liquid water pipe, when water pump operation guide bearing is injected cooling liquid and is lubricated, lowers the temperature and wash, thereby cause environment unhygienic, waste water resource.Because the structural limitations of long-shaft pump under the spatial guide blade formula liquid of this structural type, the weight of the whole rotor part of water pump and axial force are all by the thrust-bearing above the pump holder or motor bears, the cantilever of the axle of water pump is very long, guide bearing and axle be easily wearing and tearing again, matching gap increases, the vibration values of water pump operation increases, thereby 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, so 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.Because the water pump of this structure is to adopt case butt coupling to carry out spindle, 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, increases the installation and maintenance cost.Easily corrode because of direct the contacting with medium of the axle of this structure water pump, water pump is when pumping Korrosionsmedium, and what the axle of water pump all adopted all is stainless steel, causes the manufacture cost of water pump too high.Owing to the above-mentioned reason of this structure water pump, cause the Security of water pump not high, working life is long, lift is not high, the degree of depth is not long under the liquid.
Long-shaft pump under the spatial guide blade formula liquid of rolling bearing structure pattern, between spatial guide blade, pillar and connecting tube, be provided with rolling bearing assembly, this rolling bearing assembly adopts seal with O ring to cooperate with the spatial guide blade upper end, the 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 bearing unit places the spatial guide blade upper end, has increased the jib-length of pump shaft between impeller and bearing, has reduced the stiffness of pump shaft.In the process of water pump at high speed operation, the swing of impeller and pump shaft is very large, thereby causes the damage of rolling bearing assembly, affects the normal use of water pump, reduces the working life of water pump.Occur because water pump O shape circle and black box in long-term using process have failure phenomenon, this medium that can cause water pump to be pumped enters in the rolling bearing assembly, destroys the working environment damage bearing of rolling bearing; Add exhaust port is not set on the bearing unit, during water pump operation, the heat that black box and bearing produce can make the air in the pillar expand, can't discharge pillar, thereby 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 the impact of above reason is arranged, make that the degree of depth falls short of under the liquid of water pump, lift is not high enough.
In the long-shaft pump, long because of the axial dimension of spatial guide blade owing to being directly to adopt spatial guide blade to be combined to form pump chamber all under the present spatial guide blade formula liquid having two kinds of structural types now, so the pump shaft of water pump is long and affect machining accuracy, waste raw material; Water pump spindle all is to adopt impeller balance hole to carry out balance to equilibrium of forces, and the phenomenon if equalizing orifice is blocked then causes the axial force balance poor effect, obtains abundant balance for making the water pump axial force, and the impeller balance hole design is very large, thereby reduces the efficient of water pump.Therefore the quantity of water pump vane assembling is restricted, and affects the lift of water pump.
