Measure the inside diameter of the seal face, the length of the spring, and the diameter and thickness of the stationary seat to estimate the size of a component mechanical seals.
You
now have the correct pump for your application, but you need a mechanical seals
to ensure that your operations work smoothly. They are an essential component
in a wide range of industrial and commercial applications, preventing leakage
as well as dangerous emissions.
So,
how can you know whether you have the correct seal for your pump?
Here's
all you need to know about gauging a mechanical seal...
What Exactly Are Mechanical Seals?
This
device prevents fluid and gas leakage during conveyance via rotating equipment
such as pumps and mixers. They are often made up of both fixed and rotational
components that work together to provide a tight sealant.
They
come in a variety of designs, arrangements, and materials to handle liquids and
gases at a variety of pressures, temperatures, and speeds.
What Are the Most Common Mechanical Seals
Components?
They
are critical components of industrial pumping systems. Using the proper seals
is essential for maintaining a regulated flow of liquid, preventing leaks and
cross-contamination, and maintaining a high degree of cleanliness.
However,
before you can correctly measure your seals, you should become acquainted with
its components. Though each seal has its own set of components, mechanical
seals usually include four main sections:
To
sealant against the stationary part, the sealant face is attached to and
rotates with the shaft.
Secondary
sealant are used to provide sealing around the mating ring, gland, and in
housing.
Stationary
seats are installed in the housing and do not rotate together with the shaft.
When
the pump is not functioning, springs or other mechanical loading mechanisms are
used to apply axial force and maintain a static seal.
How Are They Determined?
You
must isolate each component and calculate its dimensions independently to precisely
measure your seals:
Take
the stamp face off the spring and measure its internal diameter. This will
define the size of the shaft or sleeve.
Determine
the length of the spring once it has been detached from the sealant face.
Take
measurements of the stationary seat's exterior diameter, interior diameter, and
thickness.
Once
you've determined your measurements, locate and cross-reference the correct
sealant for your application.
How to Choose the Best Mechanical Seal for Your
Process?
Now
that you understand how to measure mechanical sealant, the next step in
choosing which mechanical seal you want is to ensure it fits the design and
material criteria for your operations.
In
processing they are classified into three types: cartridge, component, and gas.
A
cartridge sealant is a self-contained item that contains the sealing components
that have been pre-assembled and pre-programmed by the manufacturer. Depending
on the use, they might have one or two seals.
A
component sealant is made up of a spinning unit and a stationary seat that is
housed in housing.
Because
a gas sealant does not employ a wetted barrier fluid, the seal faces rely only
on a thin layer of air or nitrogen. These are often used in situations that
demand optimum protection against leakage or contamination.
These
materials can affect how well a sealant works and how long it will last before
requiring repair. Typically, the principal sealing surfaces are formed of a
hard substance, such as silicon carbide, ceramic, or tungsten carbide, in
combination with a softer material, such as carbon. Depending on the pressure,
temperature, and chemical qualities of the liquid within, several alternatives
can be employed.
American
seal & packaging can keep your operations going smoothly by offering
anything from non-chemical exterior sealant to cartridge-mounted double sealant,
as well as a comprehensive range of support systems such as fluid distribution
units, easy-clean systems, and a variety of additional configurations.
