Abstract
The invention discloses a flushing structure for preventing a sealing ring from being worn. A sealing ring is arranged between a pump body and an impeller; an interface is formed in a position, which is positioned on the sealing ring, on the pump body; and a flushing pipeline which is connected with an external flushing source is arranged on in interface. The flushing structure has the characteristics tha: the structure is simple; and the external flushing source is introduced into the surface of the sealing ring, so that heat produced by the sealing ring in the running process of a pump is lowered, the service life of the sealing ring is prolonged, cost consumption is lowered, and disassembly and assembly work is reduced.
Description
Technical field
The present invention relates to the fluid conveying machine technical field, be specifically related to a kind of flushing mechanism that prevents single-stage cantilever centrifugal pump seal wears.
Background technique
Seal ring is mounted on impeller and the pump housing, prevent the wearing and tearing of impeller and the pump housing, play the effect of friction pair, seal ring produces amount of heat in the pump running, very easily damage, be that easily damaged parts needs often to change, and in order to reduce loaded down with trivial details in cost and the disassembly process, be most important the working life that prolongs seal ring.
Summary of the invention
The object of the invention is to overcome above-mentioned not enough problem, a kind of flushing mechanism that prevents seal wears is provided.
The technological scheme that the present invention adopts for achieving the above object is: a kind of flushing mechanism that prevents seal wears, between the pump housing and the impeller seal ring is installed, the position that the described pump housing is positioned at seal ring offers interface, and the flushing line that is connected with flushing source, outside is installed on the described interface.
Described flushing line by jiont treatment on interface.
Described flushing line is equipped with flange with the end that outside flushing source is connected.
Characteristics of the present invention are: simple in structure, and the seal ring surface is injected in flushing source, outside, thereby reduced the heat that seal ring produces in the pump operation process, prolonged the working life of seal ring, reduced cost consumption, also reduced disassemble and assemble work.
Description of drawings
Fig. 1 is structural representation of the present invention.
Wherein: 1, flange 2, flushing line 3, joint 4, interface 5, seal ring 1, seal ring 27, impeller 8, the pump housing.
Embodiment
As shown in Figure 1, between the pump housing 8 and the impeller 7 seal ring is installed, seal ring can be comprised of seal ring 1 and seal ring 26, seal ring 1 is enclosed within the outside of seal ring 26, the position that the described pump housing 8 is positioned at seal ring 1, seal ring 26 offers interface 4, by joint 3 flushing line 2 is installed on the described interface 4, and described joint 3 is screwed in the interface 4 and with flushing line 2 and welds together, the described flushing line the other end is equipped with flange 1, and described flange is connected with outside flushing source; During use, washing solution is injected into the surface of seal ring 1 by flushing source, outside by flange 1, flushing line 2, joint 3, interface 4, thereby the heat that reduction seal ring 1, seal ring 26 produce in the pump operation process, the working life of prolongation seal ring.
The above; only be the better embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technological scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
Claims (3)
1. prevent the flushing mechanism of seal wears, it is characterized in that: between the pump housing (8) and the impeller (7) seal ring is installed, the position that the described pump housing (8) is positioned at seal ring offers interface (4), and the flushing line (2) that is connected with flushing source, outside is installed on the described interface (4).
