Description
Technical field
The present invention relates to a kind of eccentricity gauge of screw pump rotor, belong to mechanical device field.
Background technology
Screw pump mainly includes two core components：Rotor, stator, the screw rod of screw pump are referred to as rotor, and screw rod bushing claims
For stator.Rotor profile is made up of single or double spiral camber, installed in bore of stator, is rotated and is realized pumping function.Rotor is straight
Footpath, eccentric throw and helical pitch are the important parameters of direct reflection screw pump architectural characteristic.The size of eccentric throw directly influences pump
Performance, efficiency and life-span, the size of centrifugal force is also directly determined, so as to have influence on the abrasion of the vibration of pump, noise, or even stator
Deng.But, in current screw pump production process and think little of the verification of eccentric throw, also lack simple calibration tool to complete
Verifying work.
The content of the invention
The technical problem to be solved in the present invention is to overcome existing defect to be examined there is provided a kind of eccentric throw of screw pump rotor
Tool, it is simple in construction, it is easy to operate, it can quickly and efficiently complete the verification to eccentricity of rotor.
In order to solve the above-mentioned technical problem, the invention provides following technical scheme：
A kind of eccentricity gauge of screw pump rotor, including detector and verification contrast device, the detector include bottom
Seat and dial gauge, the base are cuboid, and the upper surface of the base is provided centrally with connecting seat, the center of the connecting seat
Through hole is provided with, the side of the connecting seat is provided with screw, and four angles of the lower surface of the base are provided with placement pin, institute
The bottom surface for stating placement pin is provided with outer inclined-plane, and angle of inclination is 55 °~65 °, the pointer set insertion through hole of the dial gauge,
And the screw is screwed in by screw be fixed, the pointer of the dial gauge is passed by through hole；The verification contrasts device
The difference of dumbbell shape, end circular cylinder radius and middle part circular cylinder radius is equal to the eccentric throw of rotor to be verified, and the length of middle part cylinder is small
In the length of the base.
Further, the angle of inclination of the outer inclined-plane for laying foot plate surface is 55 °.
A kind of eccentricity gauge of screw pump rotor of the present invention, it is simple in construction, it is easy to operate, can be quickly and efficiently complete

Length is less than the length of base 11.
Operation principle：Detector is placed on verification contrast device, makes pointer termination contact middle part cylinder and is set to
Zero-bit, then detector is placed on the rotor for needing to verify, minimum point is found out in the position of moving detector, and observes dial gauge
Whether zero-bit is in, confirms whether eccentric throw is qualified with this.
A kind of eccentricity gauge of screw pump rotor of the present invention, it is simple in construction, it is easy to operate, can be quickly and efficiently complete
The verification of paired eccentricity of rotor.
Finally it should be noted that：The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention,
Although the present invention is described in detail with reference to the foregoing embodiments, for those skilled in the art, it still may be used
To be modified to the technical scheme described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic.
Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., should be included in the present invention's
Within protection domain.
