Abstract
The utility model discloses a special centrifugal pump, which comprises a pump body, an impeller, a water inlet and a water outlet. The utility model is characterized in that the inner of the pump body is provided with a channel warehouse for preposition water supply, and the channel warehouse is positioned in front of the impeller. The chamber wall of the channel warehouse over against the impeller is provided with a window cover, and the impeller is a semi-open type double-blade impeller. Because the structure of the present dredge pump is thoroughly reformed, the utility model preferably solves the problem of plugging prevention and can rapidly eliminate the plugging problem. The utility model is suitable for transportation and treatment sewage and is suitable for transportation of similar liquid medium which contains large granular suspended substance.
Description
The utility model belongs to centrifugal pump, particularly a kind of sewage centrifugal pump that is used for inhomogeneous fluid.
The centrifugal water pump that is used for blowdown faces the most thorny issue to be exactly anti-plugging and to get rid of blocking problem.Existing Ordinary Centrifugal Pumps can be used as pollution discharge pump, but poor performance.
The purpose of this utility model is to propose a kind of blowdown centrifugal water pump that can solve anti-plugging preferably and be easy to get rid of the plugging fault problem.
Blowdown centrifugal water pump of the present utility model comprises the pump housing, impeller, and water intake, water outlet is characterized in that being provided with in the said pump housing passage storehouse of a preposition water supply, it is positioned at the impeller front, is provided with the window lid over against the passage Cang Qiangbi of impeller; Said impeller is the semi-open type two blade impeller.
The inboard of said water intake is provided with clappers that play the non-return effect.
Said impeller below also is provided with the pumping chamber, is provided with a clean-up port above the pump housing, and the pumping chamber communicates with the clean-up port.
Main good effect of the present utility model has:
1. owing to adopted the semi-open type two blade impeller, allow the large-size particle that passes through between blade, the particulate matter maximum diameter that embodiment provides reaches 75 millimeters, so that the utmost point is not easy is blocked;
2.,,, only need a few minutes just can resume operation as long as can implement the operation of removing obstacles just open the window lid because of being provided with the passage storehouse of water supply in the pump housing even blocked;
3. this pump inlet capacity is strong, and liquid level is above to be used so be adapted to be mounted within, and wide application, for example vehicle-mounted flood fighting water drainage, suction under ground piping sewage all are suitable for.Also can recoil after the blowdown and remove contamination, carry out maintenance operation then, provide convenience for carrying out production strictly in line with rules and regulations, improve the housekeeping operation condition by clean-up port and passage thereof;
4. external motor can adopt belt drive, can guarantee safe operation.
Be illustrated below in conjunction with embodiment and accompanying drawing thereof:
Fig. 1 is a structure principle chart of the present utility model.
Fig. 2 is the left view of Fig. 1.
Referring to accompanying drawing.Token name claims as follows among Fig. 1,2:
1. water intake 2. clappers 3. water outlets 4. protect liner plate 5. spiral cases 6. impellers 7. Sealings 8. tank filler sleeves 9. bearing 10. impeller shafts, 11. reservoir compartments 13. discharge orifices, 14. safety valves, 15. passage storehouses, 12. pumping chambers, 16. windows and cover 17. quick-release handles, 18. clean-up port cap assemblies, 19. clean-up ports, 20. pump housings.
The blowdown centrifugal water pump of illustrated embodiment, comprise the pump housing 20, impeller 6, water intake 1, water outlet 3, it is characterized in that being provided with in the said pump housing 20 a passage storehouse 15, the usefulness of fixing a breakdown as water channel with in safeguarding, its chamber is positioned at impeller 6 fronts, chamber wall over against impeller 6 is provided with window lid 16, be easy to find out failure cause, and got rid of by opening the window lid; Said impeller 6 is the semi-open type two blade impeller, and the space is big between the blade of this impeller, is not easy to stop up.Be provided with clappers 2 that play the non-return valve action in addition in the inboard of water intake 1, be used to prevent sewage backflow.Use the clappers back just need not in intake pipe, safety check or bottom valve be set again.As shown, clappers 2 are installed on the inclined-plane of water intake 1 the inner, utilize hinge to be connected and fixed, and open during suction function in passage, just can close automatically because of action of gravity during decompression in passage, play the safety check effect.During the impeller operation, sewage, is discharged from water outlet 3 by impeller 6 by clappers 2 inlet passage storehouses 15 from water intake 1 again.Be provided with in the chamber of the spiral case 5 at impeller 6 places and protect liner plate.Wherein protect liner plate 4, be easily damaged parts, wear and tear, can change for regular check because of the solid particle in the aqueous medium of getting dirty impacts.For simplicity, it and window lid 16 is designed to one, has so also just satisfied convenient disassembly, the needs easily of fixing a breakdown.Impeller 6 is got the semi-open type double blade structure, and this structure can be avoided the generation of blocking phenomenon basically.In addition, also be provided with back blade at the back side of impeller 6.Back blade is set avoids impeller dirt deposition behind.Sealing 7, tank filler sleeve 8, bearing 9, impeller shaft 10, reservoir compartment 11 constitute conventional impeller shaft supporting, sealing, lubrication system among the figure.Damage cast iron pump body in order to prevent overvoltage in the chamber, also be provided with safety valve 14 in the said pump housing.Below impeller blade, also be provided with pumping chamber 12, increase work efficiency with it.Simultaneously, also be provided with discharge orifice 13 in the pumping chamber of the pump housing.This discharge orifice 13 is located at low level, and surplus liquid can be clean by this hole discharging in the chamber, and it helps transportation, preserves and prevent ponding.The 15th, the passage storehouse constitutes one with window lid 16 together with protecting liner plate 4.For easy to maintenance, on window lid 16, also be provided with quick-release handle 17.The quick-release handle is connected with nut 17 times, is connected and fixed by the bolt and the pump housing, and the charge and discharge operations of window lid 16 is efficient and convenient, and the handling window lid does not need assistant tool.Can change after unloading for whole and protect liner plate, and fully expose impeller, be convenient to implement to remove obstacles or keep in repair.Shown in Figure 2, be provided with clean-up port cap assemblies 18 above the pump housing 20, it by cover plate, pressing plate, bridge screw, hold out against screw and form, below the assembly clean-up port 19 and passage thereof, communicate with pumping chamber 12, the cleaning that aims at the pumping chamber is cleared up and is established, and regularly removes dirty amassing, and can guarantee to bring into play the works fine performance of pump.
The blowdown of present embodiment is functional with the centrifugal water pump anti-plugging, and the largest particles diameter that can pass through between blade reaches 75 millimeters, and its flow is big comparatively speaking, the lift height all is better than standard-required, external motor V-type belt drive, can guarantee safety, getting rid of generic failure can free-hand field operation.
