The utility model provides a disassembly structure of a novel guide rod support sleeve, which has a good support effect and is easy to disassemble. The guide rod support sleeve comprises an outer sleeve and an inner sleeve, wherein one end of the outer sleeve is connected with one end of the inner sleeve through a direct connecting rib, and the guide rod support sleeve is characterized in that: the other end of the outer sleeve is connected with the other end of the inner sleeve through a forwards extending oblique connecting rib.
Description
Technical Field
The utility model belongs to the technical field of dismounting devices and methods of large diaphragm pumps, and particularly relates to a novel dismounting structure of a guide rod support sleeve.
Background
In the hydraulic end of a large diaphragm pump, a guide rod support sleeve is positioned in a cavity of the hydraulic end, and a guide rod connected with the diaphragm continuously reciprocates in the support sleeve under the thrust of a piston. The field operation practice of a large number of diaphragm pumps shows that whether the structure of the guide rod supporting sleeve is reasonable or not is crucial to the long-term, stable and safe operation of the diaphragm pump, and the specific reasons are as follows:
1) because the guide rod reciprocates in the support sleeve, the length direction of the support sleeve needs to be designed with enough space, so that the support sleeve can really play the roles of guiding and positioning the guide rod.
2) The guide rod can flexibly reciprocate in the support sleeve, and the support sleeve can be stably and reliably mounted, so that the fit relationship between the support sleeve and the guide rod is determined to be clearance fit; the matching relationship between the supporting sleeve and the cavity is transition matching.
In conclusion, the design of a supporting sleeve structure with a large supporting length, a strong guiding effect and convenience in mounting and dismounting becomes a problem to be solved urgently by designers of the hydraulic end of the diaphragm pump.
