Abstract
The utility model discloses an impellor of a shearing pump. The impellor of the shearing pump comprises an impellor body, a shearing pipe and a shearing disc; the shearing disc sleeves the axis of the impellor body and the connection part between the shearing disc and the axis of the impeller body is welded; the shearing pipe is welded on the outer side surface of the impellor body; the inner side surface of the impellor body is axially provided with a connection bulge; the connection bulge and the side surface of the shearing disc are welded integrally; the axis of the impellor body is provided with an internal thread connected with a main shaft, wherein the length of the internal thread is greater than 30mm; an internal thread, connected with the main shaft, of the impellor body has the length of 38mm. According to the impeller disclosed by the utility model, the impellor structure of the shearing pump is simplified, and the connection intensity of the shearing disc and the impellor body is improved, so that the efficient operation of the impellor of the shearing pump is ensured; the thread, connected with the shaft, of the impellor body is lengthened, so that the transmission torque increases; the assembly technology is simplified, and the installation is more convenient.
Description
Technical field
The utility model relates to a kind of Shearing pump vane wheel.
Background technology
On-the-spot Shearing pump vane wheel used is in the time that impeller is worked, mainly by shearing pipe and the shearing disk chopping mud medicine containing colloid at present.Shearing disk is by pressing plate, itself and impeller body to be compressed, and it is not slided in the time of high speed rotating.The problem that current this impeller exists is: when 1, shear pump is worked, the rotating speed of impeller is 2200 revs/min, and situation about not pressing tightly easily appears in shearing disk, causes shear pump inefficiency; 2, this impeller is assembled into together by three part accessories, therefore, cumbersome when assembling, assembly fee man-hour; 3, the bonding strength of impeller body and axle is less.
Utility model content
The utility model provides a kind of Shearing pump vane wheel, strengthens bonding strength, improves shear pump operating efficiency; Simplify the structure of impeller, install more convenient.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of Shearing pump vane wheel, comprise impeller body, shear pipe and shearing disk, shearing disk is set on impeller body axis and junction welding, on impeller body lateral surface, be welded with and shear pipe, be provided with vertically connection bump on impeller body medial surface, connection bump and shearing disk side are integrally welded, impeller body axis is provided with the internal thread being connected with main shaft, and the length of internal thread is greater than 30mm.
The length of the internal thread that impeller body is connected with main shaft is 38mm.
The utility model has been simplified the blade wheel structure of shear pump, but has improved the bonding strength of shearing disk and impeller body, has ensured the efficient operation of Shearing pump vane wheel; Increase the reach that impeller body is connected with axle, therefore increased the moment of torsion transmitting; Assembly technology has been simplified, and installs more convenient.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment: as shown in Figure 1, a kind of Shearing pump vane wheel, comprise impeller body 1, shear pipe 2 and shearing disk 3, shearing disk 3 is set on impeller body 1 axis and junction welding, on impeller body 1 lateral surface, be welded with and shear pipe 2, on impeller body 1 medial surface, be provided with vertically connection bump, connection bump and shearing disk 3 sides are integrally welded, impeller body 1 axis is provided with the internal thread being connected with main shaft, and the length L of internal thread is greater than 30mm.In the present embodiment, the length of the internal thread that impeller body 1 is connected with main shaft is 38mm, has improved the transmitting torque power of impeller body.Label 4 in Fig. 1 is and is welded to connect place.
By the change to blade wheel structure, shearing disk 3 and impeller body 1 are welded to one, to strengthen the intensity of connection, improve shear pump operating efficiency; Remove pressing plate, simplify the structure of impeller, install more convenient.
Claims (2)
