Abstract
The utility model discloses a pump body which comprises a pump casing and a liquid outlet connected to the pump casing, and a boss structure is arranged at the joint of the pump casing and the liquid outlet. The boss structure is connected with a heat tracing chamber formed by a heat tracing sleeve for medium in a heating pump through a welding member, and a circular ring is arranged on the inner side of the liquid outlet. The front surface of the circular ring is perpendicular to the axis of the pump casing, and the shape of the circular ring matches with the die pulling inclination of the boss structure. The surface of the inner channel of the pump body and the surface of the heat tracing chamber are painted with a ceramic layer. The pump body is wear resistant, high temperature resistant, safe and reliable and is long in service lifetime.
Description
Technical field
The utility model relates to a kind of pump housing, is specifically related to the horizontal pump housing in a kind of transporting system.
Background technique
Because slag fragment hardness is high, after mixing seawater, also has corrosive action, 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 declined and even make pump case occur the phenomenon of wearing and tearing perforation.And the pump housing of pump case appearance wearing and tearing perforation phenomenon can only guarantee to use by changing new pump, thereby cause the operation of transporting system to stop and the dismounting transposing of workload greatly, also caused the waste of material simultaneously.
Model utility content
The purpose of this utility model is to provide a kind of wear-resistant, high temperature resistant, long service life and the safe and reliable pump housing.
In order to achieve the above object, the utility model has following technological scheme:
A kind of pump housing of the present utility model, comprise pump case and be connected to the liquid outlet on pump case, the joint of described pump case and liquid outlet is provided with a boss structure, and this boss structure connects by a weldment the hot chamber of the companion for heat pump medium that companion's hot jacket is wrapped to form.
Wherein, described liquid outlet inner side is provided with an annulus, and the front surface of this annulus is perpendicular to the axle center of pump case.
Wherein, the shape of described annulus and the pattern draft of boss structure match.
Wherein, the inner flow passage of described pump housing surface and accompany hot chamber surface spraying ceramic layer.
Owing to having taked above technological scheme, the utility model has the advantage of:
1, neat and artistic in the utility model profile, the specialization and the standardization that have improved whole product, the anti-corrosion capacity of the pump housing is strong, in the working life of extension device, has reduced cost of production.
2, the toroidal design that the utility model pump housing liquid outlet increases, for the pump housing leaves the solder bond face of accompanying hot chamber in advance, strengthens the rigidity of the pump housing.
3, the utility model simple structure, can promote the use of.
Accompanying drawing explanation
Fig. 1 is the utility model structural profile schematic diagram;
Fig. 2 is the utility model structural representation;
Fig. 3 is the utility model companion hot jacket structural representation.
In figure: 1, liquid outlet 2, accompany hot chamber 3, companion hot jacket 4, boss structure 5, annulus 6, pump case
Embodiment
Below implement to be used for illustrating the utility model, but be not used for limiting scope of the present utility model.
Referring to Fig. 1-3, the utility model comprises pump case 6 and is connected to the liquid outlet 1 on pump case, described pump case 6 is provided with a boss structure 4 with the joint of liquid outlet 1, this boss structure 4 connects by a weldment the hot chamber 2 of the companion for heat pump medium that companion's hot jacket 3 is wrapped to form, and boss structure 4 is the round boss of diameter 75mm.
According to the contact condition with slurries, respectively on the inner flow passage surface of the pump housing and accompany hot chamber 2 surface spraying 1-3 layers pottery, and different surface of contact adopts different types of pottery to be sprayed.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here cannot give all mode of executions exhaustive.Every still row in protection domain of the present utility model of apparent variation that the technical solution of the utility model extends out or change that belong to.
