Understanding Oil Filtration And Contamination

A basic knowledge of oil filtration requirements, challenges, and solutions can make it easy to understand oil contamination and filtration. Oil filters are utilized in many types of hydraulic machinery to improve the quality of oil.

Oil filtration requirements

Filtration plays a key role in maintaining hydraulic equipment and fluids. The fluid contamination leads to corrosion, wear, unsatisfactory performance, and ultimately, the equipment failure. Most of the oil filters perform a simple function; trapping the particles in small holes and cleaning oil. The fluid passes through the filter while particles above a certain size are trapped. Engine oil filters have to deal with the following challenges:

  • To remove or mitigate contaminants that are detrimental to the engine
  • To have the ability to hold contaminants for the required service interval
  • To have the capacity to allow oil to flow through the filter and be cleaned

There are many types of oil filtration products that vary in terms of performance and efficiency. Some filters offer 50% efficiency which means they remove half of the contaminants in oil at a given particle size. We can test the efficiency of an oil filter through various techniques.Cold flow is a common term experts use to describe a condition where oil experience restrictions while passing through the filter. It happens when oil becomes thick due to high soot and sludge levels. Cold flow also happens when filtration experts put filters on high efficiency. When the unfiltered oil is allowed to circulate in the engine, it stimulates corrosion process that affects engine life. Therefore, it is important to have the filters with the right balance of efficiency, cold flow ability, and capacity.

Capacity, efficiency, and cold flow ability are three critical requirements and mandatory to ensure extended engine life and performance. Real world testing is the only way to determine an optimal balance of these three requirements.

Contamination in lubrication systems

We must first understand the issues that arise due to oil contamination in an engine. We can classify contaminants in diesel engines lubrication systems as organic and inorganic. Organic contamination or sludge is formed due to by-products of combustion and comprises more than 70% of total contaminants in diesel engines. It limits the ability of a filter to trap harmful contaminants.

Inorganic contaminant also called dust is formed due to core sand, wear metal, gasket material, and dirt. A filter’s capacity to filter out dust does not reflect its performance. High-quality oil filtration systems play effective role in holding sludge along with the dust in the oil. Controlling these organic and inorganic contaminants can effectively reduce wear in the engine and improve equipment performance.

What Are the Benefits of Using Plastic Injection Molding?

Plastic injection molding is one of the most efficient methods for producing complex plastic parts at high volume. It is not only extremely efficient, but also very flexible in use with the option to make changes to the base material throughout the production process. Let’s take a look at a few of the most pleasing qualities of using plastic injection molding:

High accuracy

Plastic injection molding is a manufacturing method that is highly accurate provided a precise mold is used. On average, the accuracy level is likely to be in the region of about 0.006 inches.

Fast and efficient

The fast and efficient nature of this type of manufacturing makes it the most popular option for producing a high volume of plastic items. However, the actual time to create each piece will vary with the complexity of the actual mold. A typical time to create each item is in the region of 15 to 25 seconds.

Keeps labor costs to a minimum

The automated nature of plastic injection molding helps to cut labor costs because this type of machinery only needs a minimal workforce to keep going. Once the actual mold is created, the machinery will keep running successfully with appropriate supervision in place.

Minimize waste

The ability to minimize waste and benefit the environment is certain to be an appealing quality for many. This type of machine is not only very efficient, but is also appreciated for the very small amount of waste produced at the time of production. It only needs to use the set amount needed to create each molded piece. Additionally, if there is any waste, this can easily be recycled elsewhere on a different project.

Easy to change production

Plastic injection molding is designed to offer great flexibility with the option to make changes throughout the production process. Several of the things that can actually be changed include the type and color of material used.

High-strength parts

The parts produced using this production method can easily vary in strength. A simple way to improve on the all-round strength of a part is to add a special type of filler to the base plastic material. This has the benefit of reducing the volume of liquid plastic which results in great strength and durability of the finished item. The ability to control the plastic strength makes plastic injection molding a great option for any industry that needs the super strong products.
