Abstract
The utility model discloses an improved pump, which comprises a pump body, an impeller and a pump shaft. The pump shaft is positioned in the pump body; and the impeller is sleeved at one end of the pump shaft. The improved pump is characterized in that a through bolt hole is formed in the sleeved end face of the impeller and the pump shaft, the impeller is connected with the pump shaft through a locking bolt, and a locking washer is arranged between the impeller and the pump shaft. The impeller of the improved pump is fastened on the pump shaft through the through locking bolt, so that the impeller, the pump body and the pump shaft are prevented from being scrapped by extrusion and collision between the impeller and the pump body when the impeller is withdrawn from the pump shaft due to reversal of a motor during early debugging of the pump.
Description
Technical field
The utility model relates to a kind of pump that medium is a drilling fluid of pumping, and is specifically related to the pump that a kind of anti-motor counter-rotating causes impeller to withdraw from from pump shaft.
Background technique
Existing pump mainly is made up of the pump housing, impeller and pump shaft, and impeller set is connected on the pump shaft, and the gap between the blade front-end face of impeller and the pump housing overcurrent conical surface is 0.5-0.8mm.During pump is debugged in the early stage; Because turning to that electric current phase sequence and motor phase sequence, pump require during the motor wiring is not inconsistent and the causes motor counter-rotating; Impeller withdraws from from pump shaft; Because the blade front-end face and the gap between the pump housing overcurrent conical surface of impeller are little, cause impeller and pump housing extrusion and collision that impeller, the pump housing, pump shaft are scrapped.
The model utility content
The utility model technical problem to be solved is: a kind of improved pump is provided; This pump makes certain improvements on former pump; The impeller that will be socketed on the pump shaft with lock bolt tightly locks together, and has avoided the debugging of pump initial stage to cause impeller and pump housing extrusion and collision to cause impeller, the pump housing, pump shaft to be scrapped because of the motor counter-rotating makes impeller withdraw from from pump shaft.
For reaching the foregoing invention purpose, a kind of improved pump is provided, comprise the pump housing, impeller and pump shaft; Said pump shaft is positioned at the pump housing; Said impeller set is connected to an end of pump shaft; It is characterized in that: said impeller and pump shaft cover contact surface is provided with the entire body bolt hole, and connects through lock bolt, and between be provided with lock washer.
In sum, this improved pump tightly locks together through the impeller that lock bolt will be socketed on the pump shaft, has avoided the debugging of pump initial stage to cause impeller and pump housing extrusion and collision to cause impeller, the pump housing, pump shaft to be scrapped because of the motor counter-rotating makes impeller withdraw from from pump shaft.
Embodiment
Below in conjunction with accompanying drawing the utility model is done detailed description.
Fig. 1 is the existing pump structural representation;
Fig. 2 is improved pump structure schematic representation.
Wherein: 1, the pump housing; 2, impeller; 3, lock washer; 4, lock bolt; 5, pump shaft; 6, entire body bolt hole.
Fig. 1 is an existing pump, and it mainly is made up of the pump housing 1, pump shaft 5 and impeller 2, and impeller 2 is socketed on the pump shaft 5, and the gap between the blade front-end face of impeller 2 and the pump housing 1 overcurrent conical surface is 0.5-0.8mm.
Fig. 2 is improved pump, comprises the pump housing 1, impeller 2 and pump shaft 5; Said pump shaft 5 is positioned at the pump housing 1; Said impeller 2 is socketed on an end of pump shaft 5; It is characterized in that: said impeller 2 is provided with entire body bolt hole 6 with pump shaft 5 cover contact surfaces, and connects through lock bolt 4, and between be provided with lock washer 3.
During existing pump is debugged in the early stage; Because turning to that electric current phase sequence and motor phase sequence, pump require during the motor wiring is not inconsistent and the causes motor counter-rotating; Impeller withdraws from from pump shaft; Because the blade front-end face and the gap between the pump housing overcurrent conical surface of impeller are little, cause impeller and pump housing extrusion and collision that impeller, the pump housing, pump shaft are scrapped.
Improved pump tightly locks together through the impeller that lock bolt will be socketed on the pump shaft, has avoided the debugging of pump initial stage to make impeller withdraw from the problem that causes impeller and pump housing extrusion and collision to cause impeller, the pump housing, pump shaft to be scrapped from pump shaft because of the motor counter-rotating.
Though describe in detail in conjunction with the embodiment of accompanying drawing, should not be construed as qualification to the protection domain of this patent to the utility model.In the described scope of claims, various modifications that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
