Abstract
The utility model discloses a pump with cooling insulation structures. The pump with the cooling insulation structures comprises a pump body, a pump shaft, an impeller, a pump cover and a motor. The pump shaft is arranged inside the pump body, a mechanical seal is arranged between the pump body and the pump cover, the impeller is arranged at the front end of the pump shaft, a motor shaft is connected with the pump shaft, and the cooling insulation structures are arranged on the pump cover and the pump body respectively. By means of the cooling insulation structures, the pump cover and the pump body are provided with clamping sleeves respectively, and cooling insulation media can pass through the clamping sleeves. The pump with the cooling insulation structures has the advantages that due to the fact that the pump cover and/or the pump body is provided with the clamping sleeves, and the cooling insulation media can pass through the clamping sleeves, the using demands under different temperature working conditions can be met when the pump is used.
Description
Technical field
The utility model relates to a kind of pump valve structure, belongs to pump valve fluid field.
Background technique
In the production of chemical industry and oil sector, raw material, semi-finished product and finished product are liquid mostly, and raw material is made semi-finished product and finished product, and needing through complicated manufacturing process, pump has played the effect of carrying liquid and the pressure flow of chemical reaction being provided in these processes.
Yet pump in use, often can run into following two kinds of operating modes: on the one hand, for the medium of the excess Temperature by pump, the pump of conventional design can not satisfy usage requirement, and the heatproof of the machine envelope of pump is had higher requirement; On the other hand, temperature-resistant when running into the requirement medium by pump is that medium can be incubated, and the pump of conventional design can not meet the demands again.
Summary of the invention
The utility model purpose provides a kind of pump with the cooling insulating structure, by the improvement to structure, so that pump can satisfy different operating mode user demands.
The technical solution of the utility model is: a kind of pump with the cooling insulating structure, comprise the pump housing, pump shaft, impeller, pump cover and motor, be provided with pump shaft in the described pump housing, be provided with mechanical seal between the described pump housing and described pump cover, described pump shaft front end is provided with impeller, and motor shaft is connected with pump shaft, offers respectively the cooling insulating structure on described pump cover and the pump housing, described cooling insulating structure is to offer respectively chuck on described pump cover and the pump housing, can be by the cooling thermal insulation medium in the described chuck.
Further technological scheme, described chuck are included in two through holes offering respectively on the described pump cover and the cavity that can pass through the cooling thermal insulation medium, and described through hole all connects with described cavity.
Perhaps, described chuck is included in the cavity of offering respectively three through holes on the described pump housing and can passing through the cooling thermal insulation medium, and described through hole all connects with described cavity.
The utility model has the advantages that: by offering chuck at pump cover and/or the pump housing, can be by the cooling thermal insulation medium, so that pump can satisfy the user demand of different temperatures operating mode in use in the chuck.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is the structural representation of pump cover among the utility model embodiment one;
Fig. 2 is the side sectional view of Fig. 1;
Fig. 3 is the structural representation of the utility model embodiment one middle pump body;
Fig. 4 is the side sectional view of Fig. 3.
Wherein: 1, the pump housing; 2, pump cover; 3, through hole; 4, cavity.
Embodiment
Embodiment one: referring to shown in Fig. 1 to 4, a kind of pump with the cooling insulating structure, comprise the pump housing 1, pump shaft, impeller, pump cover 2 and motor, be provided with pump shaft in the described pump housing 1,2 of the described pump housing 1 and described pump covers are provided with mechanical seal, and described pump shaft front end is provided with impeller, motor shaft is connected with pump shaft, offer respectively the cooling insulating structure on described pump cover 2 and the pump housing 1, described cooling insulating structure is the chuck of offering respectively on described pump cover 2 and the pump housing 1, can be by the cooling thermal insulation medium in the described chuck.Certainly, also can only offer chuck at the pump housing 1, also can only offer chuck at pump cover 2.
Preferred embodiment, shown in Fig. 1,2, described chuck is included in two through holes 3 offering respectively on the described pump cover 2 and the cavity 4 that can pass through the cooling thermal insulation medium, and described through hole 3 all connects with described cavity 4.
Preferred embodiment, shown in Fig. 3,4, described chuck is included in the cavity 4 of offering respectively three through holes 3 on the described pump housing 1 and can passing through the cooling thermal insulation medium, and described through hole 3 all connects with described cavity 4.
The present embodiment by increased respectively the chuck design on pump cover and the pump housing, passes through the cooling thermal insulation medium in use in the chuck.For the medium of the excess Temperature that passes through pump, can in chuck, lead to cooling water by through hole 3, reduce the temperature that mechanical seal is born; For the medium that the insulation demand is arranged by pump, then can in pump, pass through high-temperature water or steam, reach the effect of insulation, thereby satisfy the user demand of different operating modes.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the people who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalent transformation or modifications of doing according to the Spirit Essence of the utility model main technical schemes all should be encompassed within the protection domain of the present utility model.
