Abstract
The utility model discloses a shaft coupling protection casing of centrifugal pump, include: positioning a plate; the cover body, it has inlayer protection casing and outer protection casing, outer protection casing one side is equipped with open structure, outer protection casing tip department inboard sets up outer protection casing recess, the inlayer protection casing is installed in outer protection casing, and outer protection casing passes through outer protection casing recess chucking on the positioning disk, and open structure department installation fastener for fasten outer protection casing. The utility model provides a protection casing can adjust length as required to adapt to different environment, form the protection to shaft coupling and other rotating parts. The utility model discloses reduce the kind of protection casing, reduced manufacturing cost.
Description
Technical Field
The utility model relates to a protection casing especially relates to the shaft coupling protection casing of centrifugal pump.
Background
The centrifugal pump comprises a base, a motor and a pump, wherein the motor is arranged at one end of the base, the pump is arranged at the other end of the base, and the motor is connected with the pump through a coupler. The outside of the coupler is provided with a protective cover for protecting the coupler. When motors of different models are matched with the centrifugal pump, the distances between the motors of different models and the pump are different due to different extending lengths of motor shafts, and the traditional protective cover cannot completely protect the coupling.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above problem, a shaft coupling protection casing of the better centrifugal pump of commonality is provided.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a coupling shield for a centrifugal pump, comprising:
positioning a plate;
the cover body, it has inlayer protection casing and outer protection casing, outer protection casing one side is equipped with open structure, outer protection casing tip department inboard sets up outer protection casing recess, the inlayer protection casing is installed in outer protection casing, and outer protection casing passes through outer protection casing recess chucking on the positioning disk, and open structure department installation fastener for fasten outer protection casing.
Further: an opening is formed in one side of the positioning plate.
Further: the inner layer protective cover is cylindrical.
Compared with the prior art, the utility model discloses following beneficial effect has: the utility model provides a protection casing can adjust length as required to adapt to different environment, form the protection to shaft coupling and other rotating parts. The utility model discloses reduce the kind of protection casing, reduced manufacturing cost.

Detailed Description
Example 1
Referring to fig. 1 to 10, a coupling shield for a centrifugal pump includes a puck 1.
The cover body 2 has inner protection casing 21 and outer protection casing 22, outer protection casing 22 one side is equipped with open structure 221, outer protection casing 22 tip department inboard sets up outer protection casing recess 222, inner protection casing 21 is installed in outer protection casing 22, and outer protection casing 22 passes through outer protection casing recess 222 chucking on positioning disk 1, and open structure 221 department installation fastener 223 (the form of outer protection casing fastening bolt is adopted in the embodiment) for fastening outer protection casing 22.
The outer protection casing recess can set up to one or multichannel as required, sets up to the twice in this embodiment, is located the left end and the right-hand member of protection casing respectively. The connection mode dismouting of outer protection casing recess and positioning disk is convenient, practices thrift the cost.
In this embodiment, an opening 11 is formed on one side of the positioning plate 1. Is favorable for disassembly and assembly.
In this embodiment, the inner protective cover 21 is cylindrical.
The positioning plate is connected with the pump 100 through positioning plate fastening bolts, and the pump 100 is provided with reserved mounting holes for connecting the positioning plate fastening bolts. The inner protective cover is cylindrical, is moved into (installed in) the outer protective cover, and then clamps the outer protective cover groove of the outer protective cover with the positioning disk. And according to the distance between motor and the pump, adjust the inlayer protection casing to suitable position, screw up outer protection casing fastening bolt again, whole shaft coupling protection casing is accomplished the installation.
The protective cover is simple and firm to install, protects the coupler in a radial all-around mode, and is divided into an inner layer and an outer layer. When the protective cover is matched with motors of different models, the distances between the motors of different models and the pump are different due to different extending lengths of the motor shafts, and the problem can be perfectly solved by the drawing structures on the inner layer and the outer layer of the protective cover.
Under the condition of matching with different motors, the rotating parts (pump shaft, motor shaft and coupling) can be completely protected. The design reduces the variety of the protective cover, enhances the universality of the protective cover and reduces the production cost.
Also shown in the drawings are motor 200, base 300, etc.
Example 2
The basic structure is the same as that of the embodiment 1, and the difference is that the protective cover is provided with an observation hole for checking the running conditions of the pump and the motor. The specific form is many, for example, round or long-strip-shaped observation holes are arranged on the circumference of the outer layer protective cover and the inner layer protective cover.
Above only do the preferred embodiment of the present invention, the protection scope of the present invention is not limited to the above embodiment, all belong to the technical scheme of the present invention all belong to the protection scope of the present invention. For those skilled in the art, several modifications can be made without departing from the principle of the present invention, and such modifications should also be considered as the protection scope of the present invention.
