Beginner’s guide to hydraulic seal size, types, and protection methods

Hydraulic seals and supplies
Perfect hydraulic seals and supplies must have the quality to block the leakage of liquid or fluid through a cylinder. Moreover, a good hydraulic seal should have the following abilities to withstand under
What are the uses of Hydraulic seals and supplies?

  • Extreme pressure
  • High pressure
  • Transverse forces inside a cylinder.

So, the hydraulic seal function is basically about the prevention of leakage of all type of fluids. But this function is not just about prevention from leakage. This system actually uses a fusion of some special types of seals.

How many types of Hydraulic seals and supplies are there?

There are many kinds of seals and supplies which engineers use in Hydraulic seals and supplies systems.

These are:

  • Static Seals
  • Piston seals
  • Dynamic Seals
  • Lip Seals
  • Double-lip seals

Here we are giving you the brief description of each of the above seals and supplies.

Static seals:

Engineers normally use these types of seals in parts which are non-moving.

Piston seals:

These types of seals help to save leakages of fluid throughout the head of cylinder. Furthermore, it permits the pressure of the targeted fluid to increase in one side of the piston. And also helps the cylinder to make it broaden or back off.

Dynamic Seals:

When engineers seal two parts they make use of a Dynamic Seals between them. As they know that it has a rotary or a reciprocating motion. Such as in a hydraulic cylinder, piston to barrel seal has used.

Lip Seals:

Lip seals are actually the other name of dynamic seals. And they are mostly used for the purpose of rotating shafts. But manufacturers generally make use lip hydraulic seals and supplies in applications that have low pressure.

Double-lip seals:

These types of seals are generally used in contact with shafts of two-sided pumps or motors.

How many types of rings are there which engineers use in Hydraulic seals and supplies?

Here are some types of rings that engineers also use in hydraulic seals to make them perfect in all ways.

Such as:

  1. Type O-Rings
  2. Backup Rings
  3. Wear rings

Brief description of each type of ring

O-Rings

O-Rings are good and favorable seals. And engineers use these seals actually in the following applications:

  • Dynamic
  • Static

Backup Rings

Manufacturers use hydraulic seals and supplies backup rings with the combination of O-Rings especially in fusion of high pressure and approval among parts. As they have the ability to force the O-ring inside the space and between the mating parts.

A successful installation totally depends on the nature of the applications. There are various kinds of procedures for a successful installation. And we have to follow several processes whether a new seal is installed or it is replacing the first one.
What are some useful tips for a successful installation of Hydraulic seals and supplies?

There are many specific things which engineers generally have to keep in their minds. And these things actually need a great care and attention when considering them. Furthermore, these are some helpful tips which will help you completely for a better and problem free installation.

  • Lubrications
  • Protection
  • Cleanliness
  • Heating
  • Right tools

Some deep information and details about the useful installation of Hydraulic seals and supplies

Lubrication

It is very important that before the installation, engineers must lubricate both

  • Seal
  • Sealing path.

There are many kinds of lubricants which increase the durability and also help to stop scratching.

Furthermore, the names of other lubricants are:

  • Silicone grease or oil
  • Fluorocarbon fluid
  • Petroleum base
  • Barium grease

It is very essential that lubricate which you select to lubricate must be suitable and adaptable with the raw material.

Protection:

Manufacturers know the ways to secure the hydraulic seals and supplies from severe type of corners and burrs. Because this type of surface will completely harm them.

Some extra tips for successful installation of Hydraulic seals and supplies

Cleanliness

Engineers have to make sure that for better hydraulic seals, all tools have cleaned using lint-free cloths. And also clean the seals as dust can affect very badly the performance of the sealing. Furthermore, dust can also be the main reason to its failure.

Heating

Always heat the targeted seals before installation in order to check the elasticity. Try to soak the seal into a hot lubricant as it will really help you to soften the seal compound. And it will also help to strengthen its elasticity.

Furthermore, this process will obviously help in a successful installation of seal. But it is a necessary element that avoid to heat beyond the limits of the temperature. Because it can damage the seal.

Right tools

For perfect hydraulic seals and supplies, you must use the right and perfect tools. Because using right tools will obviously help to eliminate the possibilities of damaging and indenting.

For a successful installation, read, interpret and figure out the best process of installation. Whenever there is a doubt in your mind regarding any part, try to get help from an expert.

Furthermore, you should attain the perfect knowledge about hydraulic seal installation and not try to do it without complete and authentic information.

What are the common failures of hydraulic seals and supplies?

For a successful hydraulic-cylinder operation, always select the perfect seal. And for a perfect seal operation, engineers must have full knowledge about its working and installation. Because seals are very important and essential for hydraulic cylinders.

Since, they have the ability to avoid the leakage of the fluids among various components. As we have described above that there are two main categories of hydraulic seals. Like static and dynamic. Manufacturers use dynamic seals basically between two parts.

Hydraulic seals and supplies can fail and maybe there is a need to replace them. But the expert design engineers can have the ability to reduce the factor of damaging these seals. Engineers have to keep in mind the following main causes of failures and must try to avoid these harmful impacts.

These harmful impacts are:

  1. Wear
  2. Fracture
  3. Hardening
  4. Scarring
  5. Contamination
  6. Improper installation
  7. Chemical Erosion

Hardening

In the condition of high temperatures of fluids the hydraulic seals turn into a hard state. And it usually occurs in the applications in two conditions like:

  • High-velocity heat generation from rubbing operations
  • High temperatures of fluids

Scarring

When we talk about the operating life of these seals, the tools of installation and its procedures are very crucial. The installation which is unsuitable will cause serious dents and cuts in seal lip. And it will also seriously damage the efficiency of hydraulic seal.

But it will also mix the foreign elements in the fluid. Hence it is a serious type of failure in the installation of Hydraulic seals and supplies.

Furthermore, description of remaining causes of failure are given below

Contamination 

oil seal manufacturers in china

When engineers introduce into the hydraulic rod the following elements like:

  • Jetsam
  • External flotsam.

Then they will cause the pollution in the hydraulic rod. And as particles add these elements like:

  • Mud
  • Dirt
  • Powder,
  • Many other tiny factors with the piston.

Hence all these particles make the seal dirty. So, it will lose the capability of avoiding the piton area from dirt.

Improper installation

As we have already described that unsuitable installation may cause a serious problem in the hydraulic seals and supplies. It can create problems like:

  • Uncleanliness
  • Unsafe handling
  • Contamination
  • And incorrect sizing of the chosen seal.

So, before finalizing the design, its seals must be selected for better performance.

Chemical Erosion

Always try to select reliable hydraulic seal supplier to avoid chemical erosion. Because it will create the serious problem as it clashes a corrosive fluid. When engineers make use of unreasonable materials, it will obviously result in the following conditions:

  • Durometer
  • Swelling
  • Shrinkage of the seals.
