Mechanical seals are leakage control devices, which
are found on rotating equipment such as pumps and mixers to prevent the
leakage of liquids and gases from escaping into the environment. A
mechanical face seal is an important component of variety of pumps used
in chemical, petrochemical and process industry.
The seal is designed to fit around the shaft or some
part connecting to the shaft in a way such that the leakage between the
two regions is acceptably small under all circumstances of operation.
Wherever the rotating shafts are used, shaft seals
find their place with them. Generally rotating shafts either run into
fluids where the fluid is sealed by the shaft seal or are supported by
bearings, which are in turn sealed by a shaft seal. Thus almost all
rotating equipment require a shaft seal.
The various types of mechanical equipment that utilize shaft seals are as follows:
The various types of mechanical equipment that utilize shaft seals are as follows:
-
Aerospace industries where motors and engines in rockets and turbo jets.
-
Water pumps used in irrigation, pumping of fertilizers and insecticides.
-
Swimming pool pumps and garbage disposal pumps, dishwashers and washing machines use small sealed pumps.
-
Water turbines, steam turbines, feed pumps, and nuclear reactor cooling pumps.
-
The petroleum, chemical, textile and drug industries all use pumps extensively in their respective processes.
-
All automotive engines, compressors, air conditioners.
-
Ship propeller shafts as well as its auxiliary equipment in ship yards.
Solidworks Model 2
The sliding clamp is manually placed in the T-slot
and screwed against the die clamping edge. Once the high-pressure
spindle has been adjusted to suit the height of the clamping edge, the
clamping force is built up by turning the hexagon nut in a clockwise
direction. The clamping force achieved depends on the tightening torque
selected with the torque wrench. If the parts are not rigid, tighten the
high-pressure spindle using the hexagon nut until there is no play.
Applications:- For clamping and locking dies on press beds and rams
- On beds of machine tools
- When the available space is limited
SolidWorks is a 3D solid modelling package which
allows users to develop full solid models in a simulated environment for
both design and analysis. Designing in a modelling package such as
SolidWorks is beneficial because it saves time, effort, and money that
would otherwise be spent prototyping the design. SolidWorks software
provides users with an intuitive 3D experience that maximizes the
productivity of your design and engineering resources to create better
products faster, and more cost-effectively.
Today, most manufacturers of automobiles, arm and construction equipment, recreational vehicles and other gasket-using equipment apply three-dimensional (3D) computer-aided design
(CAD) software to create product models. The technology allows
designers to produce engine and ultimately whole vehicle designs solely
on computers. By modelling in three dimensions, the designers can do
electronically all the spatial fitting of a components with respect to
clearances and tolerances, avoiding a lot of rework on actual hardware.
CAD software supplies the tools for both design and
manufacturing to create and explore various shapes, mechanisms, and
structures. The software enables all the geometries to effectively
communicate together. In turn, you are able to view and troubleshoot a
concept without prototyping, cutting, forming, etc. Solid models are
characterized by the deļ¬nition of 3D volumes, both interior and
exterior. In addition to volume and mass property data, Solid models
usually provide cross section and interference detection.
