Abstract
The utility model relates to a high pressure chemical centrifugal pump impeller locking device, including first, two impeller nut and stopping screw, first, two impeller nut's different screw pitch, first, two impeller nut fit on the pump shaft to the internal rotation by centrifugal pump pump shaft outer end and tightly with impeller fixed connection on the pump shaft, outer end face guard terminal surface in the pump shaft outside of an impeller nut, be equipped with on an impeller nut's the outer terminal surface with the off -center screw in pump shaft axle center, the stopping screw is screwed the screw and is supported tight pump shaft terminal surface outward.
Description
Technical field
This utility model is related to a kind of centrifugal pump, specifically a kind of high pressure chemical industry centrifugal pump impeller locking device.
Background technology
The impeller of centrifugal pump is generally connected directly between on pump shaft using single or multiple nuts, under the environment that runs up,
The fixation of generally impeller easily loosens, and causes the damage of pump.
The content of the invention
This utility model provides a kind of compact conformation, and install convenient, the high pressure chemical industry centrifugal pump impeller being connected firmly is prevented
Loose device.
The technical solution of the utility model is：A kind of high pressure chemical industry centrifugal pump impeller locking device, it is characterised in that：Including
First and second impeller nut and stopping screw, the pitch of first and second impeller nut is different, and first and second impeller nut is by centrifugal pump pump
Axle outer end is inwardly combined on pump shaft and tightly impeller is fixedly connected on pump shaft, and the outer face of the first impeller nut covers in pump shaft
Outer face, the outer face of the first impeller nut is provided with the screw with the biasing of pump shaft axle center, and stopping screw screws screw and pushes against pump
Axle outer face.
This utility model is designed with the screw thread of different pitch in pump shaft of centrifugal pump, for screwing and presses the of tight impeller
First, two impeller nut, and in the first impeller nut outer face the screw of a bias is designed for tightening stopping screw, stopping screw
Enough frictional force is produced with pump shaft outer face after eccentric position is tightened, prevents first and second impeller nut from loosening, so as to ensure leaf
Wheel is reliable, even if impeller reversion, reversing can ensure that pump is not damaged, effectively prevents impeller from loosening, and improves centrifugal pump and uses peace
The complete and life-span.
Description of the drawings
Fig. 1 is this utility model structural representation.
In figure：The pump housing 1, impeller 2, pump shaft 3, the first impeller nut 4, the second impeller nut 5, stopping screw 6.
Specific embodiment
It is described further below in conjunction with drawings and Examples.
Shown in Fig. 1：A kind of high pressure chemical industry centrifugal pump impeller locking device includes first and second impeller nut 4,5 and retaining spiral shell
Nail 6, the pitch of first and second impeller nut 4,5 is different, and first and second impeller nut is inwardly combined on by the outer end of pump shaft 3 in the pump housing 1
On pump shaft 3 and tightly impeller 2 is fixedly connected on pump shaft, the outer face of the first impeller nut covers in pump shaft outer face, the first leaf
The outer face of wheel nut is provided with the screw with the biasing of pump shaft axle center, and stopping screw 6 screws screw and pushes against pump shaft outer face.
