Description
Technical field
The utility model relates to a kind of novel liquid sewage pump.
Background technique
In existing structure, impeller is double shrouded wheel; and be one mechanical seal; when carrying some to contain the sewage of particle or fiber; easy clogging impeller also makes mechanical seal lose efficacy; blocking or mechanical seal fail, and pump all obtains and stops immediately, in order to overcome the above problems; in order to make pump can the long-time running when the wastewater media containing particle or fiber, special design be optimized to existing structure.
Summary of the invention
The purpose of this utility model solves the problems referred to above existing in prior art, provides a kind of novel liquid sewage pump.A kind of novel liquid sewage pump of the utility model design, comprise the pump housing, suction pipe, impeller, pump cover, protecgulum, connecting base, axle, mounting plate, clamping coupling, motor rack, motor, lifting pipe, it is characterized in that: on protecgulum, offer tapped hole, twist in tapped hole and be connected to adjusting screw, adjusting screw is relative with pump housing outer wall, protecgulum is relative with impeller, pump shaft is provided with twice mechanical seal, first mechanical seal is arranged on pump cover place, second mechanical seal is arranged on connecting base lower end, in connecting base upper end, bearing is installed, bearing housing is contained on pump shaft.The utility model has the advantages that, cross fluid space large, the sewage with certain granules can be carried, and with certain dissection, be applicable to the working environment that the degree of depth under liquid is less than 1m.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and example, the utility model is elaborated.
Accompanying drawing is the utility model structural drawing.
Embodiment
A kind of novel liquid sewage pump in figure, comprise the pump housing 1, suction pipe 2, impeller 3, pump cover 4, protecgulum 5, connecting base 6, axle 7, mounting plate 8, clamping coupling 9, motor rack 10, motor (not drawing in figure), lifting pipe 11, it is characterized in that: on protecgulum, offer tapped hole 12, twist in tapped hole and be connected to adjusting screw 13, adjusting screw is relative with pump housing outer wall, protecgulum is relative with impeller, pump shaft is provided with twice mechanical seal, first mechanical seal 14 is arranged on pump cover place, second mechanical seal 15 is arranged on connecting base lower end, in connecting base upper end, bearing 16 is installed, bearing housing is contained on pump shaft.
Adjust gap between impeller and protecgulum, excesssive gap by adjusting screw between the impeller of this practical nova and protecgulum, volumetric loss is large, gap is too small, has certain wearing and tearing, makes power excessive, supercurrent runs, and in order to reasonably ensure the stable operation of water pump, gap is adjusted to 0.5mm.Secondly, impeller blade adopts the structural type of the large cornerite of front opened single channel, and it is large that this structural type crosses fluid space, can carry the sewage with certain granules, and with certain dissection.
Adopt twice mechanical seal.This twice mechanical seal is connected, and separate work, plays the effect of duplicate protection.Close pump side mechanical seal is first mechanical seal, because may particle be had in medium, so dynamic and static ring material is Tungsten carbite/Tungsten carbite, and second mechanical seal dynamic and static ring material Tungsten carbite/graphite.
This New sewage pump bearing plays a supportive role, owing to being a bearing, also the size just determining the axle of this pattern pump can not be long, also the axial dimension just determining this pattern pump can not be long, also determine the applicable situation of this novel liquid sewage pump, be applicable to the working environment that the degree of depth under liquid is less than 1m.
Coupling adopts folder coupling.First, this coupling is the folder shell utilizing two subdivisions vertically, is clamped by bolt to realize diaxon and connects, and by the frictional force transmitting torque between two half-coupling surfaces, utilizes that straight pin is auxiliary to be connected.Secondly, when the assembling of this coupling and dismounting, axle does not need to move axially, so mounting or dismounting easily.In a word, this coupler structure is simple, and mounting or dismounting are convenient, are applicable to low speed (the highest peripheral velocity is 5M/S), without impacting, and the stable occasion of oscillating load.
