Abstract
The utility model is related to a kind of shield pump bearing moving sealing ring, including step, outer openings groove, spiral shape step, step is located at the outside upper measurement of shield pump bearing moving sealing ring, outer openings groove is located at the peripheral bottom of shield pump bearing moving sealing ring, and spiral shape step is located at the inwall of shield pump bearing moving sealing ring.Traditional oblique angle direct through groove is replaced with spiral shape step, the fast shortcoming of the flow velocity before can improving can slow down stream speed oil, and distribution of oil mass is uniform, and can improve sealing property.
Description
Technical field the utility model is related to a kind of shield pump bearing moving sealing ring, belongs to shield pump bearing sealing neck
Domain.
Background technology
Traditional shield pump bearing moving sealing ring, as shown in Figure 1, Figure 2, including step 2, outer openings groove 3, oblique angle direct through groove
4, step 2 is located at the outside upper measurement of shield pump bearing moving sealing ring 1, and outer openings groove 3 is dynamic with sealing located at shield pump bearing
The peripheral bottom of ring 1, oblique angle direct through groove 4 is located at the inwall of shield pump bearing moving sealing ring 1, because inwall is direct through groove,
During use, stream speed oil is too fast and uneven, so as to influence sealing property.
The content of the invention
The purpose of this utility model, which is to provide one kind, can slow down stream speed oil, and distribution of oil mass is uniform, and can improve sealing
The shield pump bearing moving sealing ring of performance.
In order to achieve the above object, design is a slows down stream speed oil, and distribution of oil mass is uniform, and can improve sealing
The shield pump bearing of energy is highly desirable to moving sealing ring.The technical solution of the utility model is to provide a kind of shield pump bearing and used
Moving sealing ring, including step, outer openings groove, spiral shape step, step is on the outside of shield pump bearing moving sealing ring
Enclose, outer openings groove is located at the peripheral bottom of shield pump bearing moving sealing ring, and spiral shape step is located at shield pump bearing with close
Seal the inwall of rotating ring.
Original oblique angle direct through groove is replaced with spiral shape step by the utility model, in use, stream speed oil is slow, and
Uniformly, moreover it is possible to improve sealing property.
The utility model has the advantages that：
1st, stream speed oil is slowed down, and distribution of oil mass is uniform；
2nd, sealing property is improved.
