Abstract
A reversion-prevention vertical submerge slurry pump comprises a pump body. A threaded pump shaft is arranged in the pump body, and a motor support is arranged on the pump body. The reversion-prevention vertical submerge slurry pump is characterized in that a one-way bearing is arranged on the extending end of the pump shaft and the motor support, an inner ring of the one-way bearing is fixedly connected with the extending end of the pump shaft, and an outer ring of the one-way bearing is matched with the motor support. The one-way bearing of the reversion-prevention vertical submerge slurry pump adopts a wedge block type overrun clutch working principle, and has a good reversion-prevention effect. The reversion-prevention vertical submerge slurry pump has the advantages of being small in size, large in transmission torque, stable in operation and the like.
Description
Technical field
The utility model relates to the mechanical structure field of pump, especially a kind of structure of slag stock pump.
Background technique
The structure of disclosed a kind of vertical slag slurry pump on the market, it comprises the pump housing, the interior pump shaft that has screw thread that is provided with of the said pump housing, impeller is connected with pump shaft.Its kind of drive is that screw thread rotation advances defeated material medium to be transported to the outlet end of slag stock pump by the entrance point of slag stock pump; Slag stock pump with this structure; Thereby often, user's misoperation causes the pump shaft counter-rotating in actual use because managing the refluence of inner high voltage liquid with the drive electrode reversal connection of slag stock pump or when the slag stock pump is shut down; And then make pump shaft and impeller come off, sometimes even with the pump cover bursting, give and produce, safeguard and bring a lot of inconvenience; Thereby, be necessary thoroughly to solve on this basis the problem that pump shaft reverses.
The model utility content
The purpose of the utility model is to use the Wedge type over running clutch working principle, provides a kind of permission pump shaft to rotate along the screw propulsion direction, at its vertical slag slurry pump under liquid of anti-reverse that is automatically locked in the other direction.
The technological scheme of the utility model is achieved in that
Provide a kind of anti-reverse vertical slag slurry pump under liquid; It comprises the pump housing; The pump shaft that has screw thread is set in the said pump housing, and electric machine support is arranged on the pump housing, it is characterized in that: said pump shaft shaft extension end and said electric machine support are provided with a unilateral bearing; The inner ring of said single-phase bearing is fixedly connected with said pump shaft shaft extension end, and the outer ring of said single-phase bearing cooperates with electric machine support.
The vertical slag slurry pump under liquid of aforesaid anti-reverse is characterized in that: said unilateral bearing is fixed on the pump shaft through two axle head snap rings.
The vertical slag slurry pump under liquid of aforesaid anti-reverse, it is characterized in that: said electric machine support is the cylndrical surface with the unilateral bearing outer ring and cooperates, and said unilateral bearing moves axially with pump shaft.
The said unilateral bearing of the utility model has adopted the Wedge type over running clutch working principle, has played good anti-reversing effect, and it is little to have a volume size, and carry-over moment is big, and advantage such as operate steadily.
Description of drawings
Fig. 1 is a kind of embodiment's of the utility model a structural representation.
Embodiment
Embodiment below in conjunction with accompanying drawing 1 explanation the utility model:
Referring to Fig. 1, provide a kind of anti-reverse vertical slag slurry pump under liquid, it comprises the pump housing 1, the pump housing 1 top is sequentially provided with output tube support 4, bearing support 5, electric machine support 8, bearing support 5 is affixed with output tube support 4, and electric machine support 8 is affixed with bearing support 5; In the said pump housing 1 pump shaft 6 that has screw thread is set; Impeller 2 is connected with pump shaft 6; Be provided with backplate 3 with impeller 2 corresponding parts in the pump housing 1; It is characterized in that: said pump shaft 6 shaft extension ends and said electric machine support 8 are provided with the unilateral bearing 7 of a Wedge type over running clutch working principle job, and the inner ring of said single-phase bearing 7 is fixedly connected with said pump shaft 6 shaft extension ends, and 7 outer rings of said single-phase bearing cooperate with electric machine support 8.
Said unilateral bearing 7 is fixed on the pump shaft 6 through two axle head snap rings.
Said electric machine support 8 is the cylndrical surface with unilateral bearing 7 outer rings and cooperates, and said unilateral bearing 7 moves axially with pump shaft 6.
Though preceding text have shown the detailed embodiment of the utility model, obvious, the art personnel of skill institute of related domain revise and change can carry out part under the prerequisite of the utility model; The content of mentioning in the description of preceding text and the accompanying drawing is not as the restriction to the utility model only as illustrative case, has the vertical slag slurry pump under liquid of anti-reverse of above-mentioned technical characteristics, all falls into the utility model protection domain.
