Axial mechanical seal
The axial mechanical seal of the present invention comprises a housing with an enclosed annular space containing fluid under pressure; a seal ring and a carrier supporting the seal ring are axially and radially displaceable in the annular space when subjected to heavy vibrations; a series of pockets are annularly disposed in the housing and each includes a compensating element having a portion in contact with the fluid under pressure that yields to accept the fluid displacement resulting from the axial movement of the seal ring and its carrier inside the annular space.
In an axial mechanical seal including a housing with an annular inner spacecontaining fluid under pressure, a seal ring and a carrier means supporting said seal ring in said annular space, said seal ring and said carrier means being axially and radially displaceable in said annular space when subjected to heavy vibrations: aseries of pockets annularly disposed in said housing; compensator means in each said pocket, said compensator means consisting of resilient yielding means having a portion in contact with said fluid under pressure; said resilient means yielding in saidpocket to accept fluid displacement as a result of axial movement of said seal ring and said carrier means in said annular space.
Basically, an axial mechanical seal includes a pair of flat sealing faces forming part of a rotating seat ring and a stationary sealing ring; these flat faces are urged into fluid sealing engagement with one another by the application of force(usually springs) to one or both of them. In addition, these faces are subjected to the pressurized fluid contained within a portion of the seal housing into which a rotatable shaft extends.
Vibrations which are transmitted from the machine to the seal cause difficulties, especially in large units such as turbines, sterntubes, etc. Depending on the frequency and the amplitude of these vibrations, there occurs periodical lift-off ofthe sealing faces resulting in significant leakage therebetween. In extreme cases, this effect can cause very short suction and discharge periods in the sealing gap with High Speed leakage flow and extreme high pressure differences leading to erosion ofthe sealing surfaces and rapid damage of the seal. These vibrations may be divided into radial and axial movements. Radial movements lead to the sliding of the sealing ring and the seat ring in the radial direction of the faces of each other; however,these movements are, in most cases, accepted by standard axial mechanical seals. On the other hand, axial movements generate forces in the area of the seals which may be divided into mass forces and hydraulic forces. In order to reduce mass forces,parts subject to such forces are usually made as light as possible. Also, by adjusting the load of the springs urging the faces in contact with one another, the area of resonance can be avoided.
The hydraulic forces are significantly larger than the mass forces as considerable amounts of fluid must be displaced and suctioned within very short time intervals. Because of the above-mentioned periodical lift-off, these hydraulic forces maylead to a constant opening of the seal faces as the forces in the springs are not capable of restoring the contact of the sealing faces in the short time intervals. This condition leads to a constant and very high leakage, eliminating the advantage oflow leakage and high life expectancy of axial mechanical seals as compared to other types of seals.
It is therefore an object of this invention to provide a seal which is capable of tolerating vibrations without the aforementioned negative effects.
The present invention therefore provides a series of pockets annularly disposed in the housing an axial mechanical seal and of compensator means in each of these pockets. The compensator means consist of resilient means having a portion incontact with the fluid under pressure and yielding in the pockets to accept the fluid displacement caused by the axial movement of the seal ring and the seal ring carrier means when they are subject to high vibrations.
The scope of applicability of the present invention will become apparent from the detailed description given hereinafter; it should be understood, however, that the detailed description, while indicating preferred embodiments of the invention, isgiven by way of illustration only since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art.
Basically, the present invention provides compensators in the housing of an axial mechanical seal, which compensators are capable of accepting the displaced fluid without high flow velocity and forces and of disposing of this fluid according tofrequency.
