It is also important to understand that not all hydraulic oil filters would typically same one purpose.
Normally,a suction filter precedes a hydraulic pump at the suction port or otherwise submerged in the reservoir mostly attached along the suction line before the pump.
In this case, a rather large filter is preferable to handle huge flow rate and miniaturize larger pressure differential.
This type of filter is designed with a higher micron rating that buffers the pump from harmful hydraulic fluid contaminants that circulates within the medium.
It is strategically positioned at the pump"™s outlet to protect the fragile and sensitive components such as actuators, valves and instrumentation from contamination emanating from the pump.
The filter media element deployed in such a filter can remove a higher percentage of minute fluid contaminants.
Return filter may be located either inside the fluid reservoir or in-line (at the control valve).
It is available in different assembly styles.
The location of this filter allows all the system medium to flow through it before directing it to the fluid reservoir.
This type of filter is designed with media material that can trap and remove debris generated from the hydraulic system.
In an elaborate hydraulic system, some sections usually carry extremely sensitive components and only receives a fraction the medium flow.
Pilot line pressure filter is installed at critical system juncture to check properly system medium cleanliness level.
Other new hydraulic or lube systems are installed with off-line filter systems.
Off-line filter is predominantly self-contained filter system.
It consists of power source (pump-motor) and an array of filtration flexibility to clean hydraulic fluids before circulating in the hydraulic system.
It mainly gets connected to system reservoir.
There are hydraulic systems where shutting down for service does not stand a chance like high flow and low-pressure systems.
Hence, they need a duplex low pressure, high flow filter.
This type hydraulic oil filter can handle high viscosity and high flow media.
The duplex low pressure, high flow filter may constitute of up to 22 filter media materials in each vessel.
It extends life of system components.
Use of a single filter assembly means that you are bound to experience downtime when there is a breakdown, service or cleaning the filter media element.
In other applications like in power generation, the condition is highly undesirable.
Therefore, it is prudent to use a duplex high-pressure filter.
Duplex has identical filter housing; one in operation while the other one on standby.
It also has an integral valve occasionally used to divert the medium flow when one needs servicing.
There is no system shutdown experience while using duplex high-pressure filter.
It is wise to note that correct hydraulic oil filter and installation can guarantee years of durable system components as.
Of course, it will also improve system performance.
And more importantly, this guarantees affordable system maintenance since contamination-related failures are contained.
In this chapter, I am going to cover various hydraulic oil filter specifications design and materials.
Of course, I will also touch on the cutting-edge technologies in hydraulic oil filters.
A proper hydraulic oil filter choice will ensure efficient and effective hydraulic system.
Besides, it guarantees a sturdy system performance that exceeds optimal specifications.
This is because such specification gives the filter outstanding characteristics.
In particular, great particulate absorbent in fluid power, engine oil, lubrication oil as well as transmission oil systems.
What follows are the various hydraulic oil filter specifications that can help you meet acceptable cleanliness levels for different applications:
In order to keep up a robust and reliable filtration process, inevitably, you can bank on the efficacy of stainless hydraulic oil filters.
Also, it has been designed with a sound structural integrity that ensures a long service life.
For example, the refined stainless steel micronic material enables the hydraulic oil filter do ultra-filtration accuracy together with sustainable system protection.
Stainless Steel Pleated Filter Cartridge
Product customization put into consideration the following technical details: application environment, layer, mesh and wire-mesh counts.
This is to ultimately meet the filtration requirements for your hydraulic machineries.
Some of the main features include:
It is designed using synthetic fiber-glass material.
Fiber-glass hydraulic oil filter is an excellent choice for gases and liquid applications.
It offers essential protections for your hydraulic and machinery systems due to its increased particulate capture efficiency and dirt-holding capacity.
This is attributed by the typically minute and uniform fiber size made with varying qualities in dimensions.
Fiber glass hydraulic filter
Ability to enhance the structural permeability of filter media element makes it safeguard your systems from wear down, increased throughput and reliability.
There are a number of fiber-glass hydraulic oil filter for various specialty configurations: coalescing filter elements, Coreless filter elements, Industrial process filter elements and anti-static filter elements.
The main features include the following:
Hydraulic oil filter with cellulose multilayer filter media experience rather low medium flow resistance and possesses relatively high dirt-holding capacity.
Unlike stainless steel and fiber glass oil filter, paper on hydraulic oil filter it is the best in absorbing from hydraulic fluid.
Such paper filter media materials are made from wood pulp and polyester.
Paper oil filter is suitable for applications where it is necessary to remove water from hydraulic oil.
Cellulose hydraulic filterOn the other hand, polyester filters are equally inexpensive as the paper counterpart, however, it has low hygroscopic properties.
This makes it an affordable filter where little or no water removal required.
Newer filters are designed and configured for heavy-duty use.
They are mainly forged from a combination of paper and synthetic media materials.
Whereas the fiber blend improves efficiency and increases dirt-holding capacity, the cellulose effectively draws out water from hydraulic systems.
Here are some of the main features of cellulose hydraulic filters.
At this point, you should be able to determine the type of hydraulic oil filter that best suits your hydraulic filtration requirements.
Hydraulic oil filters are designed with dirt-holding capacity, which once are attained, there is an urgent need for the oil filter element overhaul.
But if changed early before using up the dirt-holding capacity, it becomes a waste of resources.
On the other hand, if you change it due past its capacity, you subject the hydraulic system to the harmful particles flowing within medium since the bypass shall have opened.
In the long run, it becomes a costly affair altogether.
The main point is to change the hydraulic oil filter when all the dirt-holding capacity is used up before the bypass valve goes on.
Continuous monitoring of hydraulic system filter element should keep you posted about the filter condition and performance of the system.
Hydraulic oil filters
Let"™s start right away to elaborate on how to change hydraulic oil filter.
It is advisable to make sure the safety of the technician before anything.
Make sure the hydraulic system is off-line, i.e., there is nothing running to avoid oil losses around the filter assembly.
To avoid contamination ingression around the workstation, use a vacuum cleaner to dust out the filter, otherwise use a clean cloth rag to carefully wipe the area.
Never use a solvent because it can contaminate the hydraulic fluid system.
Proceed to vent and drain the hydraulic oil filter assembly before dismounting it.
You may either drain the medium into the system or drain it into a bucket and transfer it to a quarantine tank.
Also, remember to recycle the quarantine oil through an off-line filter cart to remove the fluid contaminants.
Afterwards, make sure you take a sample for testing to find out whether it meet the set cleanliness level and necessary application requirements like viscosity, additive packages.
If the hydraulic oil meets the specification still use the off-line filter cart to inject it back into the system.
If you take off the lid of the filter assembly, do not drop it on the floor.
Place it on a clean lint-free cloth rag and another one on top to avoid exposure to contaminants.
Remove the used up filter element and place it aside.
Perhaps, you should wear a new pair gloves when handling the new hydraulic oil filter element.
Unpack the hydraulic filter element from its carton, however, access it from the bottom and keep the element wrapped to avoid environmental contamination ingression.
Adhering to such details will greatly extend the life of the element.
This is because most severe contaminants cannot be seen through the "œnaked eyes".
Now, may be the right moment to set the new element in place.
It should be an easy exercise if the assembly is accessible from the top.
Gently guide the filter to slide down to seat at the base of the assembly housing using the wrappings or clean gloves.
This should lower contamination cause during the overhaul.
Make sure you check out the bowl or lid for defect, otherwise opt to use a new one to avoid system contamination ingression.
Now return the filter assembly cover gasket to re-seal the hydraulic system.
Use compressor air to purge around the assembly before bringing it back on-line.
Voila!
You are through with oil filter element changeover procedure.
It"™s that simple.
In chapter 2, you saw why hydraulic oil filters have proven beyond reasonable doubt that they effectively trap and remove hydraulic fluid contaminates.
This in turn oils filter improves optimal performance, tames down the cost of repair and maintenance.
In addition, they reduce system downtime and extend service life for system components.
In this second last chapter, you are going to cover industrial applications of hydraulic oil filters.
Since hydraulic oil filters are used in vast industrial applications, we shall look at an industry at a time.
Hydraulic oil filterLet"™s get right to the main subject of this section:
Hydraulic oil filters have built a reputation for oil and gas industry, helping instrumentation technicians and engineers carry on robust filtration.
A profound research and development has resulted to specialization of in instrumentation filters that can as well as analyze the medium quality.
Furthermore, instrumentation filters are available in an array of specification for instance, sizes and pressure ratings.
Dynamism of industrial processes allow for hydraulic oil filter customization to meet varying filtration demands.
Hydraulic oil filters are best for fluid sample analyzing in most filtration systems.
This is because they can coalesce, trap particulate etc.
Factory machines together with complete lines of production rely on hydraulic oil filters to stop oil contaminates from causing irreversible damage to factory equipment.
Barine hydraulic and machinery systems are installed with hydraulic oil filter to improve the engine performance and reliability.
The huge fuel and oil reservoir of ships are built with advanced and efficient filtration mechanism that have been conveniently installed with hydraulic oil filters.
This is to make sure that engines and hydraulic systems are supplied with clean fuel and oil that has no sludge and system contamination ingestion.
These oil filters continuously and vigorously filter out oil and fuel impurities.
It thus, enables ferries and ships to reliable do their transportation schedule with no downtime.
Industrial hydraulic oil filters are used to protect offshore rigs during oil drilling.
Most drilling equipment utilizes hydraulic machines that must run at optimum performance specification.
To avoid debris, dirt and other fluid particulates from unnecessary hydraulic system breakdown, they fit hydraulic oil filters.
Fossil power generation industry is one industry that uses hydraulic oil filter to remove particles ingested in the hydraulic circuit of operations.
Before entry into the reservoir, return line filters are installed to remove particles of medium flow.
This avoids reintroduction of impurities into the system reservoir.
Hydraulic oil filters are also playing very important roles in the petrochemical processing industry as they are specially installed just after the pump.
Pressure oil filter designs are more robust to accommodate the immense full-system pressure.
The petrochemical processing plants have fragile and sensitive components, instrumentation and parts like proportional valves, meters, gauges, low pressure filters, etc.
Using hydraulic pressure oil filters provides adequate protection for such equipment.
Therefore, there is no situation where contamination will cause hydraulic system failure.
Hydraulic oil filters serve as a "˜kidney loop "˜ in industrial vehicles like bulldozers, excavators, tractors and many more.
As the engine runs, lube and oil systems circulate medium from reservoirs of hydraulic oil filters.
The purpose of the filtration is to refine the medium and avoid contaminated fluid from reaching the engine and machine moving parts.
After using up the dirt-holding capacity the filter is changed.
Having a right hydraulic oil filter housing assembly is also an important aspect to check on while making a purchase order.
You may have excellent filter media choices that excel in a number of applications, however the housing assembly must also be for the environment.
Now, whenever you want to buy a new hydraulic filter housing, first ask yourself these simple questions:
The housing assembly must meet integrity tests and regulatory compliance.
On the other hand, it should not hugely inflate the price of hydraulic oil filter or no hassle for customization.
Hydraulic filterThere are various flexible hydraulic oil filter housing assembly options, such as drain locations, steam jackets and special vent.
However,biopharmaceutical, biotech, food & beverage and pharmaceutical industries, housing assembly should meet the set stringent requirements.
It is essential to understand your hydraulic system environment and special requirements.
Make sure you confirm that the hydraulic oil filter housing assembly is made to meet critical features and match premium product standards.
The following are three lines of the housing assembly:
A. ASME rated vessels;
B. Industrial; and
C. Sanitary.
Basically, these units are designed and made from 316L stainless steel.
For sanitary ones, both the exterior and interior surfaces are expertly electro-polished.
The hydraulic oil filter housing assembly must meet ASME and ISO 9001 standards.
All the housing assemblies are designed with ease of cleanability with little obstruction to medium flow.
And, let me tell you one thing:
There is an ever-increasing demand for exceptional filter cartridge, but most people fail to recognize the integrity and construction of filter housing assembly.
You should understand that without proper housing assemblies, the filter element is useless.
The best filter element must have:
Quality hydraulic filtration processes need a quality filter cartridge as well as quality housing assembly.
A housing assembly that is up to scratch make quality its priBary goal.
As much as you will focus on quality, also pay attention to other housing assemblies that offer an economical alternative, particularly, for less critical filtration applications.
At this point, I know you"™re now enlightened about the fundamental aspects of hydraulic oil filter you should look for.
From the working principle, best material, replacement to choosing the right housing for the hydraulic oil filter.
The truth is:
With this information, you can prevent possible contaminations that can lead to hydraulic system failure.
