Abstract
The invention discloses a rust-proof feed pump wear ring which comprises a ring body, wherein a wear ring body is tightly connected on the inner wall of the ring body in a sleeved mode, and a rust-proof layer is arranged on the outer wall of the ring body. The rust-proof layer is adhered with the ring body through glue, and a plurality of wear-resisting protrusions are arranged on the inner wall of the wear ring body so that leakage loss in the pump is enabled to be reduced, and the rust-proof feed pump wear ring is low in abrasion, good in glue-together resistance, and good in stability of a rotor, reduces operation cost of a power plant, and the rust-proof layer can play a role of rust prevention.
Description
Technical field
The present invention relates to the feed water pump technical field, relate in particular to a kind of anti-rust wear ring for water-feeding pump.
Background technique
The feed water pump wear ring is easily damaged parts, and wear ring is got seal action at the high lower of pump impeller import, so the as easy as rolling off a log wearing and tearing of this part, may cause killing of pump rotor, affects flow, lift and the efficient of pump, even can affect the critical speed of rotation of pump.
Summary of the invention
Problem for above-mentioned prior art exists the invention provides a kind of anti-rust wear ring for water-feeding pump.
To achieve these goals, the technical solution used in the present invention is: a kind of anti-rust wear ring for water-feeding pump comprises ring body, the inwall of ring body is socket one wear ring closely, the outer wall of ring body is provided with resin layer, and bonding by viscose glue between resin layer and the ring body, the inwall of wear ring is provided with several wear-resisting projections.
As preferably, wear-resisting projection is arranged in several rows along the internal surface circumferential direction of wear ring.
Compared with prior art, the invention has the advantages that: the inwall of wear ring is provided with several wear-resisting projections, so that reveal in the pump that loss reduces, low wearing and tearing, anti-ly join that performance is good, rotor stability is good, reduced power plant's operating cost, resin layer can play antirust effect.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure: 1, ring body; 2, wear ring; 3, resin layer; 4, wear-resisting projection.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
As one embodiment of the present invention, consult Fig. 1, the present invention includes ring body 1, the inwall of ring body 1 is socket one wear ring 2 closely, the outer wall of ring body 1 is provided with resin layer 3, between resin layer 3 and the ring body 1 by viscose glue bonding, the inwall of wear ring 2 be provided with several wear-resisting protruding 4.The wear-resisting protruding 4 internal surface circumferential directions along wear ring 2 are arranged in several rows.
The inwall of wear ring 2 is provided with that several are wear-resisting protruding 4, so that reveal in the pump that loss reduces, low wearing and tearing, anti-ly join that performance is good, rotor stability is good, has reduced power plant's operating cost, and resin layer 3 can play antirust effect.
To the above-mentioned explanation of the disclosed embodiments, make related domain professional and technical personnel can realize or use the present invention.Multiple modification to these embodiments will be apparent concerning those skilled in the art, and General Principle as defined herein can in situation about not breaking away from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention will can not be limited to these embodiments shown in this article, but will accord with principle disclosed herein and features of novelty the widest consistent scope.
Claims (2)
1. anti-rust wear ring for water-feeding pump, comprise ring body, it is characterized in that: the inwall of described ring body is socket one wear ring closely, and the outer wall of ring body is provided with resin layer, bonding by viscose glue between described resin layer and the ring body, the inwall of described wear ring is provided with several wear-resisting projections.
2. anti-rust wear ring for water-feeding pump according to claim 1, it is characterized in that: described wear-resisting projection is arranged in several rows along the internal surface circumferential direction of wear ring.
