How to Choose the Best Oil Filtration System?

The choice of a product depends on various external factors.  Price, quality, performance, and reliability are just some the considerations when choosing a product.  The choice of industrial equipment also depends many of the same factors.

In choosing oil processing equipment, you will find that there are many different types of processing units intended for purification of different petroleum based oils  and fluids.

There are a large number of manufacturing companies specializing in oil processing systems. These systems include a wide range of equipment used to process different lubricants, hydraulic and turbine oils, and complex systems for oil regeneration.

The purchase of equipment for the filtration and purification of used oils is justified through the saving of money and resources.  Additionally, this equipment greatly helps in reducing problems with equipment failures and downtime, as well as reducing environmentally harmful waste oil products.  Overall, these modern machines greatly increase the service life of industrial equipment.

When choosing the right processing equipment for your business, strict attention should be paid to the technical specifications of the filters that will be used by the processing equipment:

  1. The physical size of the oil filter. This key component of the purification system must be small enough to save space and weight, but have high filtration performance in both volume and filter fineness;
  2. Filter Test Results.  Oil filters can be monitored in various ways, but one of the most common methods is the beta-factor test.  The beta factor is calculated by dividing the number of the larger particles trapped in the filter medium by the number of particles of the same size downstream of the filter.  For example, if the beta ratio is 10:1, it means that for every ten (10) particles that enter the filter, only one (1)passes through the filter without being trapped in the filter medium;
  3. Pore ​​size of the filter medium; and
  4. Performance and rate  flow.

According to studies conducted by General Motors, and published by the Society of Automotive Engineers (SAE), it was determined that the service life of an engine can be increased eight times by using five (5) micron filter mediums instead of the standard 40mm filter medium found in most massed produced automotive oil filters.

This means that the steady improvement of oil filtration systems will continue as the cost of new equipment rises and consumers demand better equipment with longer service lives.  There is an old saying that contends that oil does not wear out, it only becomes dirty.  In any case, keeping oil clean and free from contaminants and moisture will greatly extend the service life of your electric power equipment and hydraulic systems.

The traditional oil change therefore, is no longer necessary.  The high tech equipment available from GlobeCore can keep your insulating oils and hydraulic fluids in new like condition indefinitely.  Oil Processing units from  GlobeCore remove soot and sludge, dirt, moisture and dissolved gases.

If however, you decide to invest in oil processing equipment, it is worth taking the time to carefully consider your needs.  You will soon learn that not all systems for filtering oil are created equal.  Sometimes, bright brochures are specifically designed to confuse the customer.  As the consumer and business manager, you should make sure that filtration and processing equipment has passed all the necessary tests and has verified results of performance.  Here at GobeCore, we work with our customers to determine the best equipment that meets the needs of our customers.  GlobeCore has a very large and diverse line of oil processing equipment.  We work very closely with our customers so you get the best and most cost effective equipment to compliment the needs of your business.

Hydraulic System Assembly

Hydraulic System Installation Requirements

During the assembly and installation of hydraulic systems, the first concern is to provide easy access to the components and assemblies.  The service replacement of a system component should not require disassembling of neighboring components and hydraulic drive components.  Hydraulic systems should also not bear the weight of connecting pipes.  Additionally, loads caused by elastic deformation are undesirable and lead to future maintenance problems and should be avoided.

Sufficient pressure of hydraulic fluid should be provided in the hydraulic suction line.  The diameter of the suction line should not be less than the mean diameter of the pump’s suction inlet pipe.  The flow rate of the fluid in the suction line should also be limited to approximately 1.2 meters per second.  The resistance should be minimal with pressure in a range of between 0.02 – 0.025 MPa.  The rate of fluid flow in the drain lines of hydraulic drives with open circulation, should not exceed the flow rate in the suction line.  Otherwise, air and oil emulsion will form in the hydraulic tank when being drained.  The drain outlet should be submerged in the oil at a 45 degree angle.  The minimum clearance of the outlet from the bottom of the tank is calculated as twice the diameter of the drain pipe.

To prevent formation of air pockets, the drain outlets of hydraulic machines should be oriented in an upward direction.  If the drain line is long, its cross section should be increased to prevent pressure build up in the machine.

Connections are made by either flexible steel lines or rubber-metal hoses.  The specifications of the lines or hoses should meet the following requirements:

  • the hoses must not hang or kink;
  • sharp bends or twists are not allowed;
  • the hoses must not rub against each other and other components of the machine during operation;
  • the length of a straight part near the connection must be at least six times the external diameter of the hose.

Air removal devices are installed in the topmost point of the pipes.

Assembly and Installation of Hydraulic Machines and Hydraulic Systems

Assembly is begun by testing all components and parts ensuring that all required parts are present and on hand.  The first parts to be assembled are hydraulic assemblies, connection lines and instrumentation.  Control and cooling systems are next in the assembly process.  During assembly, all openings for the entry and exit of hydraulic fluids must be tightly sealed with plugs.  Purification and etching of internal surfaces of the pipes is mandatory.  Following the purification and etching process, the pipes are rinsed in special baths, dried with hot air and plugged until installation.  To ensure pipe integrity and performance at high pressure, they are tested before installation using twice the normal operating pressure.

The correct installation of sealing materials requires additional attention.  Dents, chips and other damage on the surface of parts for connecting and sealing is unacceptable and will lead to fluids leaks.  The size and cleanliness of contacting surfaces must comply with the existing standards and regulations.

Before installing the seals, a lint-free swab, soaked in benzene, is used to treat the seal surfaces and the surfaces they will make contact with.  Next, the surfaces are dried at room temperature until the benzene evaporates.  Only then can the seals and part surfaces be coated with the operating liquid or a lubricating material neutral to the material of the seal.

Seals must not be warped, stretched, twisted or damaged in any way.  If the sealed components do not have bevels, special assembly arbors are used for installation of seals with uneven or step-shaped parts.

Assembly and dis-assembly of positive displacement hydraulic drives must be done in accordance with the operators manual.

Filling of the System with Hydraulic Fluid

Upon completion of assembly, hydraulic fluid will be placed into the equipment.  Special attention must  be paid as to the correct type and correct amount of hydraulic fluid that will be put into the system.  The fluid must not contain water and solid particles must be removed by special filtration equipment prior to filling.

GlobeCore offers the UVR line of equipment for this purpose and it is based on unique and industry leading technology.  The GlobeCore UVR system is equipped with drying and degassing sections. Solved gases and water are removed from the oil by vacuum and the liquid is filtered.  The remaining contaminants are removed by Fuller’s Earth adsorbents.

The advantage of GlobeCore’s equipment is its versatility.  The UVR systems not only process hydraulic oils, they also process transformer oil, turbine oil, industrial oils, diesel fuel, HFO, kerosene, gas condensate and gasoline.

After using the GlobeCore Process of oil purification, the hydraulic oil is fully restored and is made to comply with and/or exceed industry standards.  After using the GlobeCore Process, your company can confidently avoid the cost of repairs and replacement of components that would have most likely failed due contaminated hydraulic fluid.

Filtration fineness cannot  exceed that of the finest filter in the hydraulic system.  Hydraulic fluid is filled into the system at special filling stations equipped with manual or mechanical drives.  The use of such stations have several obvious advantages.  (1) Availability of a tank protecting the oil from contamination during transportation, storage and filling;  and (2)  input and output fine filters providing the required fineness of filtration.

Filling of a positive displacement hydraulic system can be roughly divided into three stages: (1) The first stage is to fill the oil into the hydraulic system and remove air through the drain system.  The fluid is fed through the assembly line and into the lower drain point of the hydraulic drive.  As liquid enters the system, air is pushed out into the hydraulic tank through the top drain point;  (2) The hydraulic tank is filled to the top level; and (3) the hydraulic system is then topped off with fluid.

After completion of the these three stages, the positive displacement hydraulic drive is tested at idle with minimal rotation speed of the drive shaft.  The tests are repeated every 15 seconds. Hydraulic system filling is controlled by the rate of decrease in the hydraulic tank fluid level.  When the tank is filled, the drive motor is starts to operate at idle speed.  It operates at this speed for 3 to 5 minutes.  The system is then filled with liquid to the required level usually indicated by the mark on the hydraulic tank indicator.

Hydraulic System Operating Oil – What should we do next?

The cooling and purification of industrial hydraulic oil is a basic requirement in extending the service life of any hydraulic system.  Efficient cooling and purification solutions increase the reliability and service life of hydraulic equipment systems.  Efficient operation, along with timely prevent maintenance, will increase your long term profits.  To protect your equipment and the components of your hydraulic systems, the GlobeCore company, which operates in more than 70 countries in the field of oil purification equipment, offers a wide range of systems for reclamation and regeneration of any oil type.  This includes transformer insulating oil, hydraulic oils, transmission oils, turbine oils, and industrial oils of all types.

Used oils do not need to be used only as relatively cheap heat or energy sources any longer.  At present, it is possible to restore the used oil to its full market value.  GlobeCore has developed the GlobeCore Process for degassing, drying, and the purification of oils and hydraulic fluids.  Today, GlobeCore regeneration systems will allow your company to profit from used oils instead of having to pay for oil replacement and for the cost of disposing of used oil.

The Problem

Disposal of waste oil is becoming less and less common.  According to the latest expert conclusions, a large amount of waste oil products are constantly being generated in many industrial applications.  This rise in industrial waste oil has led to increases in handling and disposal costs and fines for violations of environmental regulations.

The Solution

GlobeCore offers an excellent solution to the problem.  The GlobeCore Process is now available for the complete restoration of used oil used in commercial applications.  The customer will no longer have to  pay for oil disposal, oil handling and for environmental licenses.  Instead, the customer can now reuse the what used to be a waste product.  A unique oil purification and regeneration process is used in a wide range of GlobeCore products.  The GlobeCore Process is environmentally sound because it does not cause the emission of unwanted gases, liquids and solid materials into the environment.  The use of the GlobeCore Process  facilitates up to a 95% conversion rate and that equates to a tremendous saving for your company in time, labor, oil and money.

GlobeCore has a line of equipment intended for the purification and regeneration of used industrial oil by removing solid particles, water, and other contaminates.  The process produces oil color improvement due to the removal of oil aging products, unwanted additives and finely dispersed asphaltenes.  The GlobeCore machines are quite simple and easy to operate.  They do not require complex adjustments and enjoy the competitive advantage of high mobility and the use of special self-reactivating sorbents for the regeneration of fluids.

Up to 90% of tar, asphaltenes, carbenes and carboids are removed from the used oil in the process of purification with mild effect on the oil’s additives.   Various solid particles and water are removed entirely with complete restoration of the oil to it’s original specification and color.

Complete GlobeCore plants may be used for the filtration and adsorption process of various types of oils, including hydraulic fluids and industrial oils.  The GlobeCore systems does not require readjustment for various oils.  They also do not require filter replacements since the regeneration and adsorption elements automatically reactivate themselves after each cycle of oil restoration/regeneration has been completed.

The uniqueness and affordability of the GlobeCore Process units makes them an excellent and cost effective investment for your company.
