various applications of metal bellow seals
The metal seal is an elastic container that can be compressed when pressure is applied to the outside of the container or extended. . .
The bellow seal with technology has various advantages and applications.
The metal seal is an elastic container that can be compressed when pressure is applied to the outside of the container or extended under a vacuum.
After pressure or vacuum release, the bellows is restored to its original shape.
In space applications, such as a reservoir with drinking water and an accumulator for collecting waste water, there are metal bellows seals.
Various liquids and gases can be measured using metal seals, as well as extreme temperatures.
Although the bellows seal can eliminate O-
It can even reduce potential leak paths to increase compatibility.
Technical products that can be similar to the original leather bellows traditionally used for fireplaces and forges.
Types and applications of bellows: valve seals: these are used between the shell and the rising rod to seal the internal part from the outside world.
In Europe, this device is mandatory in order to ban any leakage.
Load cell: when the load cell is applied pressure or strain, it will deform.
This deformation is detected by a strain gauge through which the low voltage DC flows.
Voltage fluctuations are detected and displayed on the control panel.
That is, when the Bellow seal is installed on the meter to protect it from external influences.
Vacuum Circuit Breaker: The transformer is always very large, and its voltage is very large.
Therefore, when used for high voltage, the spark is affected, so as a precaution, oxygen must be removed in the area where the spark occurs.
This is the time when a metal bellows seal is required to fully seal the spark area.
The bellows is used to seal so much volume that the inner part of the bellows is also evacuated or filled with inert gas.
Exhaust air box: in many industries such as railways and automobiles, the engine often operates and causes its own vibration.
Therefore, in order to compensate for these movements and temperature differences that cause thermal expansion, a bellows is used to connect the exhaust pipe to the funnel.
Mechanical Seal: The seal is used to close the inside of the pump from outside to prevent leakage.
When the pump shaft is turned, there must be a sealing element consisting of a fixed ring and a rotating ring.
These metal bellows seals are installed on the pump shaft.
Springs are also installed to apply enough pressure on both rings.
This spring has the form of a diaphragm (welded)bellow.
In the mechanical industry, metal bellows seals are often used in various industries such as actuators, aerospace, etc. , such as fluid management equipment such as height sensors and accumulators, lightning arresters, Volume compensator and fluid storage.
There are usually two types of formation and welding.
These are also used in medical fields such as implantable drug pumps.
