Detailed Description
Embodiments of the present application are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and intended for the purpose of explaining the present application and are not to be construed as limiting the present application.
In this document, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
As described in the background art, a high-pressure plunger pump is a common type of feed pump, for example, the high-pressure plunger pump can be used as a feed pump of a reverse osmosis membrane device, but a plunger of the high-pressure plunger pump moves repeatedly, if the filler leaks, sewage is carried out from a suction cavity to a plunger chamber, such as a drain of the plunger chamber is not smooth, and water is easily accumulated; at this time, the plunger is repeatedly moved, so that the sewage is easily supplied to the gear box, the lubricating oil in the gear box is emulsified and deteriorated, and all rotating parts (a crankshaft, a large tile, a small tile, a cross head and the like) are worn, so that the high-pressure plunger pump is damaged to influence production.
For the above reasons, this embodiment provides a water blocking ring for a high-pressure plunger pump, as shown in fig. 6 and 7, including a ring body fixedly mounted to the plunger, the ring body including a water blocking portion and a mounting portion, the water blocking portion being fixed to the mounting portion and extending radially toward the plunger, the mounting portion being fixedly mounted to the plunger by a fastener (e.g., a set screw).
Through the technical characteristics, the plunger piece capable of preventing repeated movement can bring sewage into the gear box, and when the plunger piece is used, the ring body is arranged on the plunger through the fastener, and the ring body and the plunger synchronously reciprocate.
For better disassembly and assembly of the ring body, as shown in fig. 1 and 2, in one embodiment, the ring body comprises a plurality of half rings 100, preferably two half rings 100; the two half rings are symmetrically arranged, adjacent half rings 100 are connected by a fastener 200, and a plunger mounting area 300 is formed in the middle of the connected half rings. Further, the half ring 100 has an axial abutting portion 102, and a radially extending water blocking piece 101 is provided on one side of the abutting portion 102, and the water blocking piece 101 is located close to the rotating member side of the plunger pump;
