Abstract
The invention discloses a short-neck pump which comprises a front cover, a rear cover, an impeller, a partition device arranged in a pump body, and a motor. The impeller is parallel to the end face of the pump body and eccentrically arranged on the lower portion of space in the pump body, and the partition device comprises a partition part and a flow guide part. The impeller is eccentrically arranged away from a liquid outlet, a large space is reserved for the liquid outlet to process liquid flow from the impeller, and liquid outflow resistance is reduced. Meanwhile, the flow guide part is arranged between a liquid inlet and an inlet of the impeller, liquid flow entering from the liquid inlet is processed, liquid inflow resistance is reduced, and the technical aim of improving work efficiency of the short-neck pump is achieved by combining the partition part and the flow guide part.

Preferably, the described second space right side from bottom to top gradually broadens, and described liquid outlet connects the top of described second space.
Preferably, described impeller is connected by transmission shaft driven with described motor, and described bonnet bottom is provided with for the through hole through described power transmission shaft.
It is further preferred that the inner side of described bonnet end face is centered by described power transmission shaft, the radial baffle plate that multiple projection is set.
It is further preferred that be provided with black box between described bonnet and described power transmission shaft.
Preferably, multiple reinforcement it is provided with between described diversion division and described separating part.
Preferably, the top of the connector of described diversion division and described inlet be circular arc, bottom be rectangle, be provided with the sealing ring of same shape between described diversion division and described inlet.
Preferably, the bracing frame of hollow out it is provided with between described bonnet and described motor.
It is further preferred that support frame as described above bottom arranges base.
Preferably, the bottom of described protecgulum is provided with leakage fluid dram and the bleed plug emptying liquid in the described pump housing.
Owing to technique scheme is used, the present invention compared with prior art has the advantage that
Due to the present invention away from liquid outlet eccentric be provided with impeller, left the bigger space of liquid outlet for and removed to arrange from impeller liquid stream out, reduced out the resistance of liquid；Being provided with diversion division between inlet and impeller eye simultaneously, arranged the liquid stream entered from inlet, reduced feed liquor resistance, both be combined with each other and have reached to add the technical purpose of short neck pump work efficiency.
