Abstract
The utility model relates to a horizontal middle-opened double-cylinder multistage centrifugal pump. The pump comprises a bearing component, an inner core component, cylinders and a rotor component, wherein a volute body with an up-down symmetrical split structure along the horizontal middle-opened surface is positioned among the cylinders and the inner core component, and the inner core component is arranged in the volute body. The pump has the characteristics of compact structure, convenience in manufacturing, installation, maintenance and detection and safety and reliability in operation, and can meet the working requirements on delivering trace particles or inflammable, explosive, high-temperature or high-pressure media.
Description
Technical field the utility model relates to a kind of multistage centrifugal pump, and especially a kind of being applicable to opened the double shell horizontal multi-stage centrifugal pump in level that tar conveying, crude oil or liquid gas etc. contain micro-particle and inflammable, explosive, high temperature or high-pressure medium.
The current double shell horizontal multi-stage centrifugal pump of background technique inner core is generally the radially i.e. uniform arrangement vertically of sectional type structure of subdivision, therefore need, by stator and multi-part integral disassembly, assemblies such as the pump housings, to have the problems such as inconvenient maintenance in using in repair and replacement pump inner rotor part process.
The summary of the invention the purpose of this utility model is to provide in a kind of level rational in infrastructure, easy to maintenance and opens the double shell horizontal multi-stage centrifugal pump.
For achieving the above object, open the double shell horizontal multi-stage centrifugal pump in the utility model level and comprise bearing part, inner core parts, cylindrical shell, rotor part, it is characterized in that for the volute casing along the upper and lower symmetrical subdivision structure of the face of opening in level the inner core parts are arranged in volute casing between cylindrical shell and inner core parts.
After adopting said structure, because volute casing is along opening face subdivision structure in level, being arranged on the volute casing inner rotor part after the dismounting connecting bolt can wholely take out, and has avoided existing pump equipment must dismantle inner core parts stage casings at different levels, could dismantle the situation of rotor part, thereby repair and replacement are convenient.Because inner core adopts whole extraction structure, leakage point is few, safe and reliable to operation.
The utlity model has compact structure, the characteristics such as manufacture, installation, maintenance is easy to detect.
Description of drawings 1 is for opening the overall structure schematic diagram of double shell horizontal multi-stage centrifugal pump in the utility model level.
Fig. 2 is for showing the cylinder part structural drawing as Fig. 1.
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing:
As Fig. 1,2 shows, open the double shell horizontal multi-stage centrifugal pump in the utility model level by bearing part 1, inner core parts 6, cylindrical shell 3, rotor part 4, wherein for along the volute casing 2 of the upper and lower symmetrical subdivision structure of the face of opening in level between cylindrical shell and inner core parts, the inner core parts are arranged in volute casing.While being keeped in repair, after dismounting connecting bolt 5, except cylindrical shell, other all parts both can wholely be extracted out, and transferring to safety has the workplace of maintenance condition to carry out the dismounting repairing.Because volute casing is along two the symmetrical parts that go to upper and lower of opening the face subdivision in level, open the top volute casing, after the whole taking-up of rotor part, can its interior easily damaged parts of repair and replacement.Thereby can avoid the dismounting rotor component that existing pump equipment sectional type core arrangement exists also will dismantle stator part, cause the problem that the maintain and replace part is inconvenient, workload is large, can reduce the dismounting number of times, improve assembly precision, reduce assembling difficulty simultaneously.
The utlity model has compact structure, manufacture, installation, maintenance, characteristics easy to detect, safe and reliable to operation, can meet and carry the job requirement that micro-particle or inflammable, explosive, high temperature or high-pressure medium are arranged.
