Abstract
The invention relates to a pump, and in particular relates to a lead pump for conveying molten liquid lead in a lead smelting plant and a lead product plant. The lead pump comprises a motor arranged on a base motor installing seat, a pump shaft driven by the motor, an impeller arranged on the pump shaft, and a pump housing internally provided with the impeller and externally connected with a lead discharging pipe, wherein the motor is arranged on one side of the pump shaft. The lead pump realizes overload protection on the motor and the pump shaft, solves the problem of lead blockage, and has the advantages of high efficiency, low energy consumption and stable and reliable operation because the pump housing and the pump shaft are sealed.
Description
Technical field
The present invention relates to a kind of pump, particularly the plumbous pump that is used for dissolving the liquid lead conveying of a kind of plumbous smelter and leadwork factory.
Background technique
At present, traditional plumbous pump major defect has: 1. transmission joint mode: drive motor connects by the rigid coupling device with pump shaft can not carry out overload protection, when occurring can making motor damage or pump shaft distortion when stifled slag is serious.2. pump shaft connects with bearing spider by Decorative drum, and bearing support links to each other by coupling with drive motor, connects too much stability and accuracy of manufacturing to pump shaft and makes troubles.3. original to be designed to structural carbon steel modified for the material of pump shaft, do not contain the heat resisting alloy element, and when the lead pan temperature reached 600 ℃, heat treatment began to lose efficacy, and rigidity descends.4. the original structure of pump case is cast inblock, and the flow channel shape error is large, and rough surface can't guarantee size and shape precision and the smoothness of pump case runner, and during pump operation, the internal flow turbulent flow is serious, also can cause vibrations, lowers efficiency.5. original impeller is the full-open type impeller, is divided into two-layer up and down, very low because plumbous liquid in the chamber can not in time replenish efficient through the evidence upper strata, and with the plumbous liquid amount of being divided into layer, two-layer plumbous liquid can consume part energy when converging.Blade quantity is more, is 8, makes the pump internal clearance too small, and after finishing using, plumbous liquid is difficult to be back to lead pan, causes stifled plumbous.
Summary of the invention
In order to overcome the deficiency of existing traditional plumbous pump, the invention provides a kind of can overload protection, reduce the loss of pump shaft impeller, it is reliable to operate steadily, and is not easy stifled plumbous plumbous pump.
The objective of the invention is to realize by following approach: a kind of plumbous pump, it comprises the motor that is installed on the base electrical machinery fitting seat, by motor-driven pump shaft, be installed in impeller, the in-built impeller on the pump shaft and pick out the pump case of lead pipe, described motor is installed on a side of pump shaft.
As the further optimization of this programme, described motor is by belt connection for transmission pump shaft.
As the further optimization of this programme, described pump shaft is installed in the bearing spider on the lower cylinder stent.
As the further optimization of this programme, described lower cylinder stent is made of cylinder and two flange integral solder.
As the further optimization of this programme, described impeller is fixed on the pump shaft by flat key and flow guiding nut.
As the further optimization of this programme, described impeller is half-opened impeller.
As the further optimization of this programme, described pump case is made of upper pump case and lower pump case, wherein goes up and has the labyrinth seal groove on the pump case.
As the further optimization of this programme, described to go out lead pipe be multi-section structure, joint with save between connect by pipe joint.
As the further optimization of this programme, described belt is V-shape belt.
As the further optimization of this programme, described impeller blade quantity is 6.
The plumbous pump of the present invention has been realized motor and pump shaft overload protection have been solved the problem of stifled lead, and pump case and pump shaft have been realized sealing, is that a kind of efficient is high, energy consumption is low, the plumbous pump of stable and reliable operation.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described in further detail:
Fig. 1 is structural representation of the present invention;
Fig. 2 is pump shell structure schematic representation of the present invention;
Among the figure, motor 1, belt 2, motor mount 3, bearing spider 4, pump shaft 5, base 6, lower cylinder stent 7, go out lead pipe 8, upper pump case 9, impeller 10, flow guiding nut 11, lower pump case 12, labyrinth seal groove 13.
Embodiment
As shown in Figure 1 and Figure 2, the plumbous pump of the present invention, it comprises motor 1, pump shaft 5, impeller 10 and pump case.Described motor is installed on base 6 motor mounts 3, motor 1 is positioned at a side of pump shaft 5, motor 1 is by V-shape belt 2 connection for transmission pump shafts 5, pump shaft 5 is installed in the bearing spider 4 on the lower cylinder stent 7, lower cylinder stent 7 is made of cylinder and two flange integral solder, this core structure, its strength and stiffness can guarantee the smooth running of pump; By flat key and flow guiding nut 11 half-opened impeller 10 is installed on the pump shaft 5, its blade quantity is 6, and impeller 10 is installed in the pump case; Pump case is made of with lower pump case 12 upper pump case 9, wherein goes up and has labyrinth seal groove 13 on the pump case 9, and pump case is minute half a formula digital control processing part, guarantees precision and the degree of finish of pump case runner, and pump operation is steady, and fluid resistance is little.Pump case picks out lead pipe 8, go out lead pipe 8 and be multi-section structure, for the ease of cleaning, joint with save between connect by pipe joint.
The working state of the plumbous pump of the present invention is vertically to insert lead pan, and plumbous liquid level need to not have pump case, and plumbous pump underframe keeps basic horizontal.Behind the motor plugged, the power of motor passes to pump shaft by belt, and pump shaft is by bearing spider constraint, pump shaft impeller quick rotation.Blade impels plumbous liquid also to follow fast rotational, flies to from impeller under the effect of centrifugal force, imports the pump case inner chamber, flow to out lead pipe from the pump case outlet, after plumbous liquid in the pump was dished out, the core of impeller formed vacuum area, and the plumbous liquid outside the vacuum area is by certainly reentering the region of no pressure.The circulation that goes round and begins again so just can realize the continuous conveying of plumbous liquid.
