Abstract
The utility model provides a kind of pressure energized formula centrifugal pump impeller sealing ring, by body seal ring, rubber ring, wear-resisting nonmetallic materials sealant composition.It is characterized in that：Body seal ring has a conical socket in the sealing surface direction contacted with impeller, and rubber ring is similar to conical socket shape, and is embedded in groove, and is bolted on body seal ring.One layer of wear-resisting nonmetallic materials sealant is adhered in the sealing surface direction that rubber ring is contacted with impeller.The utility model has the advantages that, when rubber ring is subject to the compression shock of centrifugal pump ante-chamber leakage flow, can be moved down along taper surface, wear-resisting nonmetallic materials sealant can be brought into close contact with impeller, so as to reduce leakage.Install rubber seal additional, just reduce body seal ring and the contact area of impeller that metal material is made, reduce friction, improve the life-span of impeller and sealing ring.
Description
Technical field
The utility model is related to a kind of self-tightening type centrifugal pump impeller sealing ring.
Background technology
Centrifugal pump is the necessaries of trandfer fluid, is widely used in all trades and professions, including all types of industries pump, Agricultural Water
Using pump and the civilian pump of life and it is applied to the high-performance of the national economy important industry such as nuclear energy power generation, thermal power generation department
Pump.But the presence of sealing ring gap, increases volumetric loss and the energy dissipation of centrifugal pump, so as to reduce the whole of centrifugal pump
Body efficiency.And metallic packing ring is larger with the friction of impeller, reduces the life-span of sealing ring and impeller.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of leakage rate that can either reduce centrifugal pump, again can
Reduce the sealing ring of friction.
The technical solution of the utility model is to provide a kind of pressure energized formula centrifugal pump impeller sealing ring, by body seal
Ring, rubber ring, wear-resisting nonmetallic materials sealant composition.It is characterized in that：Body seal ring is in the sealing surface side contacted with impeller
To there is a conical socket, rubber ring is similar to conical socket shape, and is embedded in groove, and it is close to be bolted on main body
In seal ring.One layer of wear-resisting nonmetallic materials sealant is adhered in the sealing surface direction that rubber ring is contacted with impeller.
The utility model has the advantages that, when rubber ring is subject to the compression shock of centrifugal pump ante-chamber leakage flow, can be along cone
Shape is moved downwards, and wear-resisting nonmetallic materials sealant can be brought into close contact with impeller, so as to reduce leakage.Install rubber seal additional
Circle, just reduces body seal ring and the contact area of impeller that metal material is made, reduces friction, improves impeller and close
The life-span of seal ring.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
As shown in the figure：1st, rubber ring, 2, body seal ring, 3, wear-resisting nonmetallic materials sealant, 4, impeller ante-chamber, 5, leaf
Wheel.
Specific embodiment
The utility model is further elaborated below by example and accompanying drawing.
As shown in figure 1, body seal ring has a conical socket, rubber ring and cone in the sealing surface direction contacted with impeller
Connected in star shape is similar, and is embedded in groove, and is bolted on body seal ring.It is close that rubber ring is contacted with impeller
One layer of wear-resisting nonmetallic materials sealant is adhered in front cover direction.The compression shock of centrifugal pump ante-chamber leakage flow is subject in rubber ring
When, can be moved down along taper surface, wear-resisting nonmetallic materials sealant can be brought into close contact with impeller, so as to reduce leakage.
