Description

TECHNICAL FIELD

[0001] The utility model relates to reciprocating diaphragm pump technical field, especially a large -scale reciprocating diaphragm pump diaphragm guide rod support. BACKGROUND

[0002] The diaphragm pump is used for the high concentration tailing delivery in the mineral processing industry, and the delivery slurry is delivered to the pipeline by reciprocating movement of the diaphragm to extrude the slurry, and the diaphragm guide rod reciprocally rubs in the guide rod support when the diaphragm reciprocates, and the guide rod support is made of brass, and when the lubricating oil quality is not good, the guide rod support is easily damaged, and after the guide rod support is damaged, the diaphragm pump needs to be disassembled and replaced with spare parts, which not only has high labor intensity of maintenance work, but also increases the maintenance cost. SUMMARY

[0003] In view of the above technical problems, the utility model provides a large -scale reciprocating diaphragm pump diaphragm guide rod support for solving the problems of high labor intensity of maintenance work and high maintenance cost after the wear of the existing reciprocating diaphragm pump diaphragm guide rod support.

[0004] In order to realize the above purpose, the technical scheme of the utility model is as follows:

[0005] A large -scale reciprocating diaphragm pump diaphragm guide rod support, including auxiliary sleeve, auxiliary sleeve is installed in the mounting hole of diaphragm guide rod support, and the guide rod is arranged in the auxiliary sleeve, and the outer diameter of the auxiliary sleeve is consistent with the inner diameter size of the mounting hole of the diaphragm guide rod support, the end of the auxiliary sleeve is provided with a flange, a first connecting hole is formed in the flange, a second connecting hole is formed in the position corresponding to the first connecting hole on the diaphragm guide rod support, and the first connecting hole is connected with the second connecting hole through a bolt.

[0006] Further, two jackscrew holes are further formed in the flange of the auxiliary sleeve.

[0007] Compared with the prior art, the utility model has the advantages that the worn diaphragm pump guide rod support is processed, the auxiliary sleeve is detachably installed, in the subsequent use process, when the auxiliary sleeve reaches the service life, the whole does not need to be disassembled, only the auxiliary sleeve needs to be removed and replaced, the overhaul time and the replacement of spare parts are saved.

[0013] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0014] like Figure 1-3 As shown, a diaphragm guide rod bracket of a large reciprocating diaphragm pump includes an auxiliary sleeve 3, which is installed in the mounting hole 2 of the diaphragm guide rod bracket 1, and the guide rod 4 is passed through the auxiliary sleeve 3. The outer diameter of the auxiliary sleeve 3 is consistent with the inner diameter of the mounting hole 2 of the diaphragm guide rod bracket 1. The end of the auxiliary sleeve 3 is provided with a flange 8, and the flange 8 is provided with a first connecting hole 6. A second connecting hole 5 is provided at a position corresponding to the first connecting hole 6 on the diaphragm guide rod bracket 1, and the first connecting hole 6 and the second connecting hole 5 are connected by a bolt 7.

[0015] Two top screw holes 9 are further provided on the flange 8 of the auxiliary sleeve 3 .

[0016] When using:

[0017] S1, enlarge the inner diameter of the damaged diaphragm guide rod bracket 1 to φ58mm, and machine a second connecting hole 5 of M6×15mm every 90° between the inner and outer diameters, for a total of 4;

[0018] S2, according to the φ40mm diaphragm guide rod 4 used, make an auxiliary sleeve 3 with an inner hole size of φ40mm and an outer diameter of φ58mm. The length of the auxiliary sleeve 3 is 140mm, which matches the length of the damaged diaphragm guide rod bracket 1. The auxiliary sleeve 3 adopts the flanging 8 process, the flanging 8 thickness is 10mm, and the flanging 8 size is φ78mm.

[0019] S3, at the center of the outer diameter of the auxiliary sleeve 3 and the outer diameter of the flange 8, a first connecting hole 6 is set every 90°, the position of which is consistent with the second connecting hole 5 on the diaphragm guide rod bracket 1, and two M6 bolt top screw holes 9 are set to facilitate the disassembly of the auxiliary sleeve 3.

[0020] S4, install the processed auxiliary sleeve 3 in the damaged diaphragm guide rod bracket 1, and use M6*20mm bolts 7 to fix the auxiliary sleeve 3 in the damaged diaphragm guide rod bracket 1.

[0021] S5, install the installed diaphragm guide rod bracket 1 to the original position of the equipment, and install the diaphragm guide rod 4 in the auxiliary sleeve 3.

[0022] S6, start debugging equipment.

[0023] The utility model processes the worn diaphragm pump guide rod 4 bracket and detachably installs the auxiliary sleeve 3. In the subsequent use process, when the auxiliary sleeve 3 reaches the end of its service life, it is not necessary to disassemble the entire sleeve, but only to remove and replace the auxiliary sleeve 3, which saves maintenance time and spare parts replacement costs.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
