Abstract

The utility model discloses an improved structure of a vortex pump body supporting frame. The improved structure comprises a vortex pump (10) and a vortex pump body supporting frame (20), wherein an annular groove (31) is arranged at the contact position of the inner cavity of the vortex pump body supporting frame (20) and a bearing (30), a seal ring (32) is arranged inside the annular groove (31), the inside diameter of the seal ring is smaller than the diameter of the inner wall at the correspondingly contacted pump body supporting frame (20) when the seal ring (32) is in a free state, the annular groove (31) is of an annular square groove structure, and the seal ring (32) is a O-shaped nitrile rubber ring. By adopting the improved structure, the sliding between the bearing and the pump body in the use process of the pump body bearing supporting part of the vortex pump is effectively prevented, and the phenomenon that a motor, the bearing and a sealing element of the equipment are damaged because of overheat bearing and large pump body vibration are prevented.

Description

Eddy current pump housing supporting frame improves structure
Technical field
The utility model relates to a kind of turbulence pump, especially relates to the eddy current pump housing supporting frame of a kind of use in the rubber production device and improves structure.
Background technique
In the turbulence pump that is applicable to the low-flow high-lift working condition, because of the advantages of small volume of pump, simple in structure, and because pump housing bearings part all is an iron casting, cast iron supporting frame and bearing are assembled into interference fit; Cause in use occurring easily the bearing and the pump housing and slide,, pump housing vibration overheated because of the bearing place takes place greatly, the phenomenon of parts such as damage equipment motor, bearing and Sealing.
The model utility content
The utility model slides for the bearing and the pump housing in use appear in pump housing bearings part easily that solve the turbulence pump in the existing rubber production device; Generation is overheated because of the bearing place, pump housing vibration is big; Prevent to present situation such as damage equipment motor, bearing and Sealing and a kind of efficiency of providing the phenomenon of bearing and pump housing generation relative movement, avoid the overheated eddy current pump housing supporting frame between the bearing and the pump housing to improve structure.
The utility model is to solve the problems of the technologies described above the concrete technological scheme that is adopted to be: a kind of eddy current pump housing supporting frame improves structure; Comprise turbulence pump and turbulence pump pump housing supporting frame; It is characterized in that: be provided with circular groove at turbulence pump pump housing supporting frame inner chamber and bearing contacting point; Be provided with seal ring in the circular groove, the internal diameter of the seal ring size of seal ring under free state is less than the inner diameter size at the pump housing supporting frame place of corresponding contact.After the bearing assembling, the seal ring compressive deformation is fitted closely with bearing outer ring; Turbulence pump is when normal the use; Pump shaft drives bearing inner race and ball rotates; Bearing and the surface friction drag of supporting frame of the surface friction drag that forms between bearing outer ring and supporting frame and seal ring in the conventional structure has prevented the phenomenon of bearing and supporting frame generation relative movement effectively.Thereby bearing and the pump housing in use appear in pump housing bearings part easily that solved turbulence pump to slide, and, the pump housing overheated because of the bearing place takes place vibrate greatly the technical problem of present situations such as damage equipment motor, bearing and Sealing.
As preferably, described circular groove is annular square groove structure.Effective embedded sealing ring, and make seal ring that disengaged position not take place.
As preferably, described seal ring is a nitrile butadiene rubber O type circle.Effectively increase frictional force and reliable working life.
As preferably, described circular groove is located at by turbulence pump pump housing supporting framing front end head place.Effectively increase frictional force.
The beneficial effect of the utility model is: the utility model can prevent effectively that the pump housing bearings part of turbulence pump from use occurring the bearing and the pump housing easily and sliding; Generation is overheated because of the bearing place, pump housing vibration is big, and this phenomenon of damage equipment motor, bearing and Sealing takes place.Reduction is overheated because of the bearing place, pump housing vibration is big, and phenomenons such as damage equipment motor, bearing and Sealing take place.Can obtain the comparison extensive use at rubber, petroleum chemical industry.
Description of drawings:
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed description.
Fig. 1 is the structural representation that the utility model eddy current pump housing supporting frame improves the preferred implementation of structure.
Embodiment
Embodiment
Among the embodiment shown in Figure 1; A kind of eddy current pump housing supporting frame improves structure; Comprise turbulence pump 10 and turbulence pump pump housing supporting frame 20; Be provided with circular groove 31 at turbulence pump pump housing supporting frame 20 inner chambers and bearing 30 contacting points, circular groove 31 is annular square groove structure, and circular groove 31 is located at by turbulence pump pump housing supporting frame 20 front end places; Be embedded with seal ring 32 in the circular groove 31, seal ring 32 is adopted as nitrile butadiene rubber O type circle.The internal diameter of the seal ring size of seal ring 32 under free state is less than the inner diameter size at pump housing supporting frame 20 places of corresponding contact; After the bearing assembling; Nitrile butadiene rubber O type circle 32 compressive deformations are fitted closely with bearing 30 outer rings, and bearing 30 exterior edge faces are equipped with bearing cap 33.Pump is when normal the use; Pump shaft 11 drives bearing 30 inner rings and ball rotates; Bearing and the surface friction drag of supporting frame of the surface friction drag of bearing outer ring and supporting frame 20 and 32 formation of nitrile butadiene rubber O type circle in the common structure has prevented that effectively bearing 30 and the phenomenon that relative movement take place supporting frame 20 from taking place.
