Abstract
The utility model provides a delivery pump provided with a sweeping device. The delivery pump comprises a pump body, a power transmitting device, a working transfer component, a driving shaft, a pump inlet cavity and a pump outlet cavity, and is characterized in that pipelines are respectively led out of the bottom of the pump inlet cavity and the bottom of the power outlet cavity and are communicated with a public pipeline. The delivery pump has the benefits that liquid containing sediment can be smoothly delivered; the sediment in the liquid has no influence on the operation of the pump, the fault that work components of the pump cannot be clamped by the sediment and the delivery pump can be ensured to be stably operated.
Description
Technical field: the utility model relates in a kind of conveying liquid and contains sedimentary transfer pump, particularly a kind of transfer pump that is provided with blowing cleaner.
Background technique: existing transfer pump: screw pump, centrifugal pump, Under Water Pumps, deep-well pump etc., they mainly by the pump housing, power transmitting deice, work running gear, transmission shaft, pump into the oral cavity, pump the oral cavity and form.Their in use common a kind of deficiencies that exists are: during the sludge of, fine particle Powdered when containing in the liquid that they are being carried; sludge in service can be deposited in and pump into oral cavity and work running gear place; block the work running gear of pump; cause pump not turn round and disorderly closedown; this kind situation frequently takes place; make and to shut down cleaning, reparation; just can turn round; this makes that the operation period of transfer pump is extremely short; have a strong impact on production; this problem is not well solved for a long time, badly influences the application of transfer pump when conveying contains sludge liquid.
Summary of the invention: the purpose of this utility model is; at existing transfer pump in the liquid of carrying because of containing work running gear that sludge the causes frequent generating pump problem of shutdown that is stuck, and a kind of transfer pump that can smooth and easy conveying contains sludge liquid-be provided with transfer pump of blowing cleaner is proposed.
Can realize the utility model purpose by following technical proposals, a kind of transfer pump that is provided with blowing cleaner, comprise the pump housing, power transmitting deice, work running gear, transmission shaft, pump into the oral cavity, pump the oral cavity, it is characterized in that, pump into oral cavity bottom, each outwards draws a pipeline to pump the bottom, oral cavity, they are communicated with common line.
For making the sludge in the pump housing before pump is opened, be in state of suspension, be beneficial to it outside pump is opened the liquid excavationg pump of back with conveying, common line is connected with the blowing medium supply station, in the pipeline of its connection, be provided with valve.
For avoiding blowing cleaner when not needing to purge, still to move the delivery efficiency that influences pump, pumping into the bottom, oral cavity, pumping in the common line that is connected between each pipeline of outwards drawing of bottom, oral cavity and be provided with valve.
The pressure of the blowing medium that the blowing medium supply station provides is slightly larger than the delivery pressure of pump.
When transfer pump was screw pump, Under Water Pumps, deep-well pump, blowing medium can be pressurized gas, water vapour or the liquid compatible mutually with carrying liquid.
When transfer pump was centrifugal pump, blowing medium was a liquid.
Effect of the present utility model is: it can be carried swimmingly and contain sedimentary liquid, sludge in the liquid does not have influence to the operation of pump, this is that this pump is provided with blowing cleaner, promptly in the entrance cavity of pump bottom, pump the bottom, oral cavity and respectively draw a pipeline, they are communicated with common line; Or on aforementioned blowing cleaner basis, common line is connected the blowing medium supply station, in the pipeline of its connection, valve is set; Or on aforementioned blowing cleaner basis, valve is set pumping into oral cavity bottom and pump on the common line that connects between the pipeline of being drawn the bottom, oral cavity.Aforementioned blowing cleaner can to pump in the oral cavity, sludge in the outlet plenum carries out outer flushing and flushing certainly, makes sludge with carrying the liquid rear pump external, the fault that sludge blocks the pump work parts can not occur, can make the smooth and easy stable operation of transfer pump.
Below in conjunction with drawings and Examples the utility model is further set forth:
Description of drawings:
Accompanying drawing 2 is the utility model embodiment 2 a structural representation (broken section);
Accompanying drawing 3 is the utility model embodiment 3 a structural representation (broken section).
Embodiment:
Its workflow is: after the pump startup operation, the working pressure that pumps oral cavity 6 is higher than and pumps into oral cavity 5 pressure, flow back to through outlet plenum inlet tube 8, common pipe 9, entrance cavity inlet tube 7 and pump into oral cavity 5 at the liquid that is transferred that pumps oral cavity 6, and flow velocity height, blow afloat and stir the sludge that pumps in the oral cavity 5, allow the sludge that pumps in the oral cavity 5 float on a liquid all the time, and with carrying outside the liquid output pump.
Embodiment 2, referring to accompanying drawing 2, a kind of transfer pump that is provided with blowing cleaner, transfer pump is screw pump, Under Water Pumps, deep-well pump, it by the pump housing 1, power transmitting deice 2, work running gear 3, transmission shaft 4, pump into oral cavity 5, pump oral cavity 6, entrance cavity inlet tube 7, outlet plenum inlet tube 8, common pipe 9 form.Entrance cavity inlet tube 7 is drawn by pumping into 5 bottoms, oral cavity, and pumps into oral cavity 5 UNICOMs; Outlet plenum inlet tube 8 is drawn by pumping 6 bottoms, oral cavity, with outlet plenum 6 UNICOMs; Entrance cavity inlet tube 7 is connected with common pipe 9 with outlet plenum inlet tube 8; Common pipe 9 is connected with blowing medium supply station 10, in the pipeline of its connection, is provided with valve 11.Blowing medium in the blowing medium supply station 10 is a pressurized gas, also can be water vapour or the liquid compatible mutually with carrying liquid.The pressure of the blowing medium that blowing medium supply station 10 provides is slightly larger than the delivery pressure of pump.
Present embodiment can solve embodiment 1 before pump startup if having sludge get lodged in entrance cavity or work running gear in and the problem of initiating failure.
Its workflow is: before opening pump, open valve 11, blowing medium enters and pumps into oral cavity 5, pumps oral cavity 6, blows afloat and stir precipitation sludge within it, allows sludge be in state of suspension, behind pump startup, can allow the sludge that is in state of suspension with carrying outside the liquid delivery pump, after several minutes, pump enters embodiment's 1 running state in the pump startup operation, this moment, but throttle down 11 moved in embodiment 1 running state.
Present embodiment can solve embodiment 1 or 2 for avoiding blowing cleaner still to move the problem of the delivery efficiency that influences pump when not needing to purge, because the conveying liquid that refluxes has reduced the output quantity of carrying liquid, and sludge has only that be accumulated to through certain hour just can be to the fault of trigger pump when a certain amount of, the period of the opening and closing of valve 12 can according to carry in the liquid sedimentary what determine.
Its workflow is: before opening pump, open valve 11 and 12, blowing medium enters and pumps into oral cavity 5, pumps oral cavity 6, blows afloat and stir precipitation sludge within it, allows sludge be in state of suspension, behind pump startup, can allow the sludge that is in state of suspension with carrying outside the liquid delivery pump, after several minutes, pump enters embodiment's 1 running state in the pump startup operation, this moment, but throttle down 11 moved in embodiment 1 running state; But space closure and Open valve 12 in running, how much definite the gap period is sedimentary according to carrying in the liquid.
