The custom hydraulic seals are mainly used for sealing for rotation. But it is also called the seal for rotating shaft. Moreover, it is composed of a “reinforcing ring” that fixes the oil seal.
The outer lip of the machine is called the “secondary lip” and the inner lip of the machine is called the “main lip”. Similarly, an oil seal consisting of two lips like this is called a “double lip”.
In order to seal the oil inside the main lip to prevent it from leaking, it is necessary to take care not to make a mistake in the mounting direction. Because the angle inside and outside is different.
Custom hydraulic seals must withstand extreme temperatures, high pressures and shear forces inside the cylinder.
Subsequently, these seals should prevent fluid from leaking from your cylinder.
Generally, these seals are used to prevent gas / air leaks.
Similarly, depending on the application, the seals are made of:
Shaft seals for your hydraulic pumps, motors, rotary bushings, couplings, crankshafts and wheel hubs, etc.
Furthermore, to stop water and / or dirt, a V-ring is used.
A Custom hydraulic seals is the seal mounted in the piston as a fluid seal. Moreover, a pneumatic piston seal is the seal mounted in the piston against gas leaks.
They prevent leaks and keep the oil / gas in place. With this oil, pressure builds up on one side on two sides to allow the piston rod to move back and forth. .
Furthermore, static seals are used as auxiliary elements for O-rings. In addition, the main objective is to prevent the sealing ring from entering the space between the two metal parts.
We have included in our range static seals. Such as:
Generally, seals fall into two categories:
Thin pieces interposed between two immobile surfaces; tight against each other to seal.
The sealing is done: either by compression of a flat seal; either by deformation of an O-ring. Similarly, it fills the entire volume available in the housing.
Dynamic joints are characterized: by the mobility of one of the two elements compared to the other.
Generally, all the seals used in industry are dynamic seals.
Static seals are generally flat seals.
The different types of Custom hydraulic seals used in industry are:
– flange seals,
– Seals for coupling sleeves,
– polymerized seals,
– Similarly, metal seals.
Generally, lange seals are used:
The flanges are welded or screwed to each end of the piping to be assembled.
Commonly, we insert a seal.
These flanges are held in place by bolts. So that they can withstand the pressure exerted inside the piping.
Joint for coupling sleeve:
The coupling sleeve coupling is a quick and economical way to join two ends of pipes while ensuring their perfect seal.
Furthermore, this joint is commonly called by its trade name “joint Victaulic”.
Similarly, some sleeves can resist up to a pressure of 70 bars.
In addition, the couplings for the coupling sleeve are very suitable for repairs and piping additions.
Polymerized joints, whose name comes from polymer, exist in the forms:
– Custom hydraulic seals,
– Four-lobe ring seal,
– Sectional annular seal (square, rectangular or V).
Subsequently, it is sometimes found in the flanges.
Generally, these joints are sealed:
The contact surfaces must be perfectly smooth.
Polymerized joints have the advantage of being easier and quicker to assemble. Therefore, Custom hydraulic seals are less expensive.
Joints activated by the tightening of the elements:
Pressure activated Custom hydraulic seals:
Generally, the tube-shaped metal joints are represented in two models:
One being pierced with small holes on the inner periphery of the ring;
Simultaneously, the other is not completely closed.
These two features are intended:
To keep the elasticity of the joint;
Allow it to return to its original shape when the pressure is released.
Moreover, metal gaskets must be pre-activated at the time of installation.
Metal joints of circular cross – section are the most used.
In most cases, their diameter does not exceed 60 mm.
In addition, the metal seals can be steel, copper (for threading) etc.
Precaution to take for Custom hydraulic seals:
Premature deterioration of the Custom hydraulic seals can be caused by a rise in the temperature of the fluid compared to the maximum admissible temperature.
It is estimated that an increase in temperature of 10 ° C results in a halving of the life of the seals.
One solution is to provide a sufficient number of coolers in the circuit to keep the temperature of the fluid below 60 to 65 ° C.
In rare situations there may be an incompatibility between the material of which the seal is made and certain fluids in the hydraulic circuit.
Custom hydraulic seals are components that prevent the leakage of lubricating oil and are used in machines that require lubricating oil.
It is a ring-shaped component made of metal and rubber. Moreover, it has a structure that prevents the leakage of lubricating oil by rubber. Moreover, it has a coil spring built into it.
This is an important part because if the lubricating oil does not leak. Mechanical parts may be deformed by frictional heat and become useless. It is also used in cars and motorcycles. Moreover, you can also replace Custom hydraulic seals yourself when performing maintenance.
