Abstract
The utility model provides a core package adjusting gasket of a cylindrical multi-stage centrifugal pump. The core package adjusting gasket of the cylindrical multi-stage centrifugal pump is arranged between an outer shell body of a centrifugal pump and a core package assembly and is a flat gasket. An expansion clearance is formed between the flat gasket and the outer shell body. According the core package adjusting gasket of the cylindrical multi-stage centrifugal pump, improvement is conducted on the basis of the prior art, a traditional disc spring or a winding gasket can be improved to the flat gasket, so that the structure is simple, cost is low and assembly is convenient.
Description
Technical field
The utility model belongs to the centrifugal pump field, is specifically related to a kind of core bag spacer of tubular multistage centrifugal pump.
Background technique
Centrifugal pump is flowing medium (gas and liquid, also can be the mixture of suspended particulate and gas or liquid) enter from blade rotor root (import), medium relies on the high speed rotating blade to obtain centrifugal force, produces a high pressure, from the medium transport equipment of pressure relief opening (outlet) outflow.Multistage centrifugal pump is that the plural pump that will have said function gathers together, on the fluid channel structure, the medium pressure relief opening that shows the first order communicates with the import of the second level, and the medium pressure relief opening of the second level communicates with the import of the third level, and so the mechanism of series connection has formed multistage centrifugal pump.The meaning of multistage centrifugal pump is to improve setting pressure.
The tubular multistage centrifugal pump mainly comprises frame and core pack assembly; Described core pack assembly comprises pump shaft and inner housing, and is arranged on the impeller assembly in the inner housing, and the end that its SMIS pack assembly contacts with frame generally all is provided with core bag spacer.But present core bag spacer all is to adopt dish spring or wound gasket, and this is so that the difficulty of processing of core bag spacer is large, complicated structure, and cost is higher.
The model utility content
The utility model is for above-mentioned the deficiencies in the prior art, and a kind of core bag spacer of simple in structure, tubular multistage centrifugal pump that cost is low is provided.
The utility model is achieved by the following technical solution:
A kind of core bag spacer of tubular multistage centrifugal pump, described core bag spacer are arranged between the frame and core pack assembly of centrifugal pump; Described core bag spacer is a flat gasket.
Further setting of the present utility model is, is provided with the clearance for expansion between described flat gasket and the frame.
The core bag spacer of tubular multistage centrifugal pump described in the utility model improves on the basis of existing technology, and traditional dish spring or wound gasket are improved to flat gasket, and structure is more simple, cost is cheaper, and easy to assembly.
Description of drawings
Fig. 1 is the structural drawing that core bag spacer described in the utility model uses state.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the utility model provides a kind of core bag spacer of tubular multistage centrifugal pump, and described core bag spacer 1 is arranged between the frame 2 and core pack assembly 3 of centrifugal pump; This core bag spacer 1 is mainly used in the position, adjusting play, as setting off the place mat effect.Described core bag spacer 1 is a flat gasket.Be provided with the clearance for expansion between described flat gasket 1 and the frame 2, can guarantee that like this core bag spacer 1 still can play a role under the higher temperature operating mode.
The above is preferred embodiment of the present utility model, and all equivalent variations of doing according to the utility model claim all should belong to protection domain of the present utility model.
Claims (2)
1. the core bag spacer of a tubular multistage centrifugal pump, described core bag spacer is arranged between the frame and core pack assembly of centrifugal pump; It is characterized in that, described core bag spacer is a flat gasket.
2. the core bag spacer of tubular multistage centrifugal pump according to claim 1 is characterized in that, is provided with the clearance for expansion between described flat gasket and the frame.
