Abstract:
Increasing the reliability and service life of dynamic-pump shaft seals is the most important requirement for their creation. The most common type of seals is still traditional stuffing box seals, which are controlled leakage assemblies that are periodically restored during operation. A radical change in the design of standard stuffing box seals is the transition to face packing seals with a constant pressure against the packing. It is shown that face packing seals can successfully combine the advantages of mechanical face seals and the simplicity and relatively low cost of traditional stuffin

This research explore on the effect of size and material of packing seal and discharge valve opening to the leakage rate at stuffing box for pump P7301-A. Leak at stuffing box is unavoidable due to gap exists between the pump casing and shaft. Therefore, it is necessary for a suitable sealing system which includes packing size and material to be installed on all pumps for controlling the leakage rate without damaging the pumps. It is also important for operator to know the proper discharge valve opening at which the pump should be operated to get minimum leakage. Experiment was conducted by re

The wear model of the stuffing box packing seal, particularly the surface of the protective sleeve of the shaft, is presented. Modeling was performed using the ANSYS software, using the Transient Structural module which have the built-in Archard wear model. The wear model was validated in accordance with the results of previous experimental studies considering the effect of applied pressure. It was determined that when the degree indicators in the Archard equations are m = 1.5 and n = 1.3, the proposed wear model allows obtaining sufficiently accurate wear intensity values.

Abstract:
The article is devoted to creating a refined computer model of the face packing seal (FPS) based on the solution of the two-way fluid-structure interaction (2-way FSI) problem. An approach to the average gap was proposed based on the micro-space’s working medium leakage between the friction pair’s roughness elements. Three FPS designs were studied, in which the following operating parameters were alternately changed: inlet pressure, load factor, stuffing box parameters, and friction coefficient.

Abstract Concerns about possible galvanic/crevice effects between graphite/PTFE composite type packing and stainless steel have been addressed. Natural seawater testing of simulated boat shaft/stuffing box assemblies revealed little difference in the overall crevice corrosion behavior of UNS S31603 when in contact with a graphite/PTFE composite or flax fiber type packing. While periodic rotation of the shaft showed some beneficial effect, the use of sacrificial zinc anodes was almost fully effective in preventing attack in 60-day tests.

Abstract:
The long term tightness performance of stuffing box packings, used in valves, is conditioned by the capacity of its material to maintain a contact pressure to a predetermined minimal threshold value. Due to creep, this contact pressure decrease with time depending on the creep properties and the stiffness of the housing. Assessing relaxation is a key parameter in determining the tightness performance of the stuffing box packing over time.

Abstract:
The demands on industry to reduce fugitive emissions are increasing, steadily /1/, /2/. On this background it is necessary to improve function and tightness of tightening joints like flanged joints and stuffing box packings. Function and tightness can only be guaranteed if the entire chain of parameters involved is taken in to account (design criteria, gasket factors, calculation, mounting procedure). On the field of flanged joints there are standardization projects on the way that address the topics of the new regulatory demands. Only few work is done regarding stuffing box packings, however.

Abstract:
The evaluation of the radial contact stress in a gland packing and its distribution in the axial direction at both the stem and housing interfaces is of major importance when predicting leakage. The method that uses direct measurement of this stress through the use of strain gages installed at the outer surface of the housing is not straightforward. The complexity of the problem is caused by the complex axisymmetric problem with a load variation in the axial direction. The use of analytical and numerical FE modeling can be feasible.

Abstract:
The tightness of valves, compressors and pumps is ensured by superposed braided rings installed in a system of stuffing-box. The nature of the packings material and structure, which is like a rectangular braided cord, influences the proper stuffing-box assembly behavior. During installation, a minimum compressive load is required to ensure a minimum level of tightness. A fairly large percentage of this axial compression load is transferred to the radial direction to generate the contact pressures at the packing-stem and packing-housing interfaces necessary for sealing.

The sealing of valve stems is ensured by the traditional systems of packed stuffing boxes. The performance of this type of sealing system used also in rotating equipment is dependent on the radial contact pressures generated by the packing axial compression. The mechanical behavior of a packing seal is characterized by the transmission ratio of the axial stress over the radial stress known as the lateral pressure coefficient which is one of the required characteristic used to select packing seals.

Packed stuffing-boxes are mechanical sealing systems that are extensively used in pressurized valves and pumps. Yet there is no standard design procedure that could be used to verify their mechanical integrity and leak tightness.

While the packing contact stress with the side walls is predictable using existing models there is no analytical methodology to verify the stresses and strains in the stuffing-box housing.
