Abstract
The utility model discloses a pump, which comprises a pump case (1) and a slag hole (2) connected onto the pump case (1). Besides, the inside of the joint of the pump case (1) with the slag hole (2) is provided with a boss (3). The pump has the advantages of abrasion resistance and long service life.
Description
Technical field
The utility model relates to thermal power plant slag transporting system, is specifically related to the pump housing in the transporting system.
Background technique
Because slag fragment hardness height, also has corrosive action after mixing seawater, the pump housing in the slag transporting system of thermal power plant will bear the wearing and tearing of high hardness slag and the corrosion of seawater under pressure, at the interior lateral wearing especially severe of the connection part of pump case and taphole, the slag yield of the pump housing is descended even make pump case the phenomenon of wearing and tearing perforation occur.And the pump housing of pump case appearance wearing and tearing perforation phenomenon can only guarantee to use by changing new pump, thereby causes the operation of transporting system to stop and the dismounting transposing of workload greatly, has also caused the waste of material simultaneously.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of wear-resistant, the pump housing of long service life.
For solving the problems of the technologies described above, the utility model adopts a kind of like this pump housing, and it comprises pump case and the taphole that is connected on the pump case, and the inboard of described pump case and taphole connection part is provided with boss.
Be provided with the arc transition connecting body between described boss and pump case and the taphole.
After adopting above structure, the utility model compared with prior art, have the following advantages: because the inboard of described pump case and taphole connection part is provided with boss, the thickness that the setting of this boss makes the inboard of pump case and taphole connection part be used to wear and tear also increases, make the pump housing more wear-resisting, longer service life.
As improvement, be provided with the arc transition connecting body between described boss and pump case and the taphole, it is smooth and easy that the slag fragment is flowed out.
Description of drawings:
Accompanying drawing is the main TV structure schematic representation of the pump housing of the present utility model.
Shown in the figure: 1, pump case, 2, taphole, 3, boss.
Embodiment:
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in drawings, the pump housing of the present utility model, it comprises pump case 1 and the taphole 2 that is connected on the pump case 1.Unlike the prior art be that described pump case 1 is provided with boss 3 with the inboard of taphole 2 connection parts.
In the present embodiment, described boss 3 is
The round boss of 80mm is provided with the arc transition connecting body between described boss 3 and pump case 1 and the taphole 2, that is to say that described boss 3 and pump case 1 and taphole 2 are connected with arc transition.
In addition, the pump housing of the present utility model contains 2.9～3.3(weight) C, the 26～28(weight of %) Cr of %, that is to say the carbon content and the C/Cr ratio that have improved the pump housing, the raising of first carbon content increases the integral hardness of the pump housing, the pump housing is more wear-resisting, the raising of the 2nd C/Cr ratio strengthens the ability of pump housing anti-seawater corrosion, has prolonged the working life of the pump housing.
Claims (2)
1. pump housing, it comprises pump case (1) and is connected taphole (2) on the pump case (1) that it is characterized in that: described pump case (1) is provided with boss (3) with the inboard of taphole (2) connection part.
2. the pump housing according to claim 1 is characterized in that: be provided with the arc transition connecting body between described boss (3) and pump case (1) and the taphole (2).
