Description

Technical Field

[0001] The utility model relates to the field of reciprocating pumps, and particularly relates to an internal cooling water pipeline and a reciprocating pump. Background Art

[0002] In the traditional cooling water pipeline arrangement for the packing box component jacket cooling of a reciprocating pump, two external pipelines are arranged above the packing box, one of which is a cooling water inlet pipeline and the other is a cooling water outlet pipeline. In some compact packing box components, due to the small distance between the two cooling water pipelines, the flange assemblies of the cooling water pipelines interfere with each other. To avoid interference, a set of pipelines needs to be bent outwards, resulting in complex pipelines. Content of the Utility Model

[0003] The utility model aims to provide an internal cooling water pipeline to solve the problems of small distance between the cooling water pipelines of a compact packing box component in the prior art, such as flange interference or complex pipelines.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme: An internal cooling water pipeline includes a packing box installed on a pump body. A cooling jacket is arranged inside the packing box. A first pipeline communicating with one end of the cooling jacket is arranged inside the pump body. A second pipeline is arranged outside the pump body and the packing box, and the second pipeline communicates with the other end of the cooling jacket.

[0005] Preferably, as an improvement, a plurality of packing boxes are arranged side by side on the pump body, and the cooling jackets of the plurality of packing boxes are all communicated with the first pipeline and the second pipeline.

[0006] Preferably, as an improvement, the first pipeline includes a transverse hole opened inside the pump body. A branch hole communicating the cooling jacket with the transverse hole is arranged inside the pump body. A flange assembly communicating with the transverse hole is arranged at the side end of the pump body.

[0007] Preferably, as an improvement, three packing boxes are arranged side by side on the pump body.

[0008] The principle and advantages of this scheme are as follows: In practical application, the cooling water pipeline of the packing box includes the second pipeline exposed outside the packing box and the pump body and the first pipeline inside the pump body. Compared with the prior art, a set of exposed cooling pipelines is reduced. The flange assemblies of the first pipeline and the second pipeline are at a relatively far distance. For a compact packing box component, the flange assemblies of the two cooling water pipelines do not interfere with each other, and there is no need to set bent pipelines. The overall pipeline system has a simple structure, avoiding a complex cooling water pipeline system.

[0009] A reciprocating pump adopts a built-in cooling water pipeline as described above. For such a reciprocating pump, the overall space occupied by the stuffing box assembly is smaller, there will be no interference during the pipeline installation process, the pipeline structure is simple, the reciprocating pump installation process is more convenient and smooth, while ensuring the cooling effect of the stuffing box, it is more conducive to the installation and use of the reciprocating pump in a limited space.
