Abstract
The utility model relates to a pump and in particular relates to a lead pump for dissolving and conveying liquid-state lead in lead smelting plants and lead product plants. The lead pump comprises a motor arranged on a motor mounting seat of a base, a pump shaft driven by the motor, an impeller mounted on the pump shaft, and a pump shell which is internally connected with the impeller and is externally connected a lead pipe; and the motor is arranged on one side of the pump shaft. According to the lead pump, overload protection of the motor and the pump shaft is realized, the problem that the lead is blocked is solved, seal of the pump shell and the pump shaft are realized, and the lead pump is high in efficiency, low in energy consumption and stable and reliable in operation.
Description
Technical field
The utility model relates to a kind of pump, and particularly a kind of plumbous smelter and leadwork factory is used for dissolving the plumbous pump that liquid lead is carried.
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 is connected 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 the up and down two-layer, and is 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.
The model utility content
In order to overcome the deficiency of existing traditional plumbous pump, the utility model provide a kind of can overload protection, reduce the loss of pump shaft impeller, operate steadily reliable, be not easy stifled plumbous plumbous pump.
The purpose of this utility model is achieved through the following channels: 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 arranged on impeller, the in-built impeller on 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 bearing spider on 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 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 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 utility model 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, are 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 utility model is described in further detail:
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model pump shell structure schematic diagram;
In 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 utility model, 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 bearing spider 4 on 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 pump shaft 5, its blade quantity is 6, and impeller 10 is installed in 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 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 utility model is vertically to insert lead pan, and plumbous liquid level need to not have pump case, and plumbous pump underframe keeps basic horizontal.After motor switched on power, the power of motor passed 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 pump was dished out, the core of impeller formed vacuum area, and the plumbous liquid outside 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.
