Description
Technical Field
The utility model belongs to the technical field of the diaphragm pump, concretely relates to be applied to guide arm support sleeve structure of large-scale diaphragm pump fluid end.
Background
The guide rod is connected with the diaphragm in the hydraulic end of the large diaphragm pump, and reciprocates along with the rubber diaphragm in the operation process of the large diaphragm pump, and the guide rod support sleeve can play an important role in positioning the guide rod and stabilizing the operation of the diaphragm. However, the inevitable friction between the guide rod and the guide rod support sleeve easily causes the support sleeve to fall off after long-term operation, which is not only a factor affecting the continuous operation rate of the large-scale diaphragm pump, but also a great hidden trouble affecting the safe and stable operation of the diaphragm pump. The supporting sleeve fixing device with the traditional structure adopts the mode of additionally installing the baffle plate, so that the effect is not good, and the supporting sleeve is not easy to replace by operation and maintenance personnel.
Disclosure of Invention
The utility model discloses just to above-mentioned problem, provide a guide arm support sleeve structure of diaphragm pump fluid end easy fixed and change.
For realizing the above purpose of the utility model, the utility model discloses a following technical scheme, the utility model discloses a diaphragm chamber, diaphragm chamber link to each other with the cavity, are provided with the guide arm in the cavity, and the guide arm links to each other with the indoor diaphragm of diaphragm, sets up supporting sleeve subassembly, its characterized in that between guide arm and the cavity: the support sleeve assembly comprises an outer sleeve fixed at the joint of the cavity and the diaphragm chamber, inner sleeves are fixedly arranged at the front end and the rear end in the outer sleeve, and the guide rod is arranged in a guide pipe in the inner sleeves.
As a preferred scheme of the utility model, be provided with the top cover with overcoat front end contact in the diaphragm chamber.
Furthermore, the contact part of the top sleeve and the outer sleeve is provided with mutually matched cones.
As another preferable scheme of the utility model, the outer sleeve is connected with the cavity through the inner hexagon screw; the inner sleeve and the outer sleeve are connected through a locking screw.
The utility model has the advantages that: the top sleeve of the utility model is positioned at the front end of the outer sleeve, and adopts the mutually matched conical surface contact, thereby playing the role of axial positioning for the outer sleeve according to the stress characteristic of the outer sleeve; a bolt hole is defined on the outer sleeve and is combined with the cavity through an inner hexagon screw, so that the radial positioning of the outer sleeve is ensured; the locking of guide arm support cover is realized to axial and radial two sides, promotes the security and the stability of equipment operation. The outer sleeve and the top sleeve can be both made of seamless steel pipes by machining, so that the device has the advantages of low cost and convenience in machining.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the attached drawing, 1 is a diaphragm body, 2 is a diaphragm chamber, 3 is a top sleeve, 4 is an outer sleeve, 5 is a plug, 6 is an inner hexagon screw, 7 is an inner sleeve, 8 is a sleeve, 9 is a cavity, 10 is a guide rod, and 11 is a locking screw.
Detailed Description
The utility model discloses a diaphragm chamber 2, diaphragm chamber 2 link to each other with cavity 9, are provided with guide arm 10 in the cavity 9, and the diaphragm body of guide arm 10 in with diaphragm chamber 2 links to each other, sets up between guide arm 10 and the cavity 9 and supports cover subassembly, its characterized in that: the supporting sleeve assembly comprises an outer sleeve 4 fixed at the joint of the cavity 9 and the diaphragm chamber 2, inner sleeves 7 are fixedly arranged at the front end and the rear end in the outer sleeve 4, and the guide rod 10 is arranged in a guide pipe in the inner sleeves 7.
As a preferred scheme of the utility model, be provided with in the diaphragm chamber 2 with the top cover 3 of overcoat 4 front end contact.
Further, the contact part of the top sleeve 3 and the outer sleeve 4 is provided with mutually matched conical shapes.
As another preferable scheme of the utility model, the outer sleeve 4 is connected with the cavity 9 through an inner hexagon screw 6; the inner sleeve 7 and the outer sleeve 4 are connected through a locking screw 11.
Further, a plug 5 corresponding to the socket head cap screw 6 is arranged on the cavity 9.
The outer sleeve 4 and the inner sleeve 7 are assembled according to the mode shown in figure 1; the assembled inner sleeve 7 and the outer sleeve 4 are arranged in a cavity 9 of the diaphragm pump; then the top sleeve 3 is arranged in the diaphragm chamber 2, and the top sleeve 3 is just positioned at the front end of the outer sleeve 4 in the hydraulic end and can be contacted, so that the axial positioning effect is achieved; the cavity 9 and the outer sleeve 4 are locked by the inner hexagon screw 6 to form radial positioning. And the plug 5 is screwed to ensure that the hydraulic oil in the cavity 9 is not leaked.
When the supporting sleeve assembly needs to be replaced, the supporting sleeve can be pulled out from the front end only by taking down the top sleeve 3 from the pump head direction.
It should be understood that the above detailed description of the present invention is only for illustrating the present invention and is not limited by the technical solutions described in the embodiments of the present invention, and those skilled in the art should understand that the present invention can still be modified or equivalently replaced to achieve the same technical effects; as long as the use requirement is satisfied, the utility model is within the protection scope.
