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.

Flushing of Hydraulic Systems Found in Industrial Equipment and Mobile Machinery

Hydraulic System Contamination

In accordance with widely accepted industrial standards, preventive maintenance processes that remove contaminates from hydraulic systems can produce the following benefits and results:

  1. The effective Service Life of hydraulic motors, pumps, valves and distribution devices can be doubled.
  2. Hydraulic system warranties can be extended by as much as two years due to the reduction in the risk of hydraulic system component failure during the warranty period.  Fluid purity however, must still be monitored and controlled and the hydraulic system must be cleaned annually.
  3. Equipment downtime is reduced.
  4. The cost of transportation of equipment to repair facilities is reduced or eliminated.

Even if oil and hydraulic filters are changed completely, it still does not guarantee that the hydraulic system will be completely free of contaminants.  Solid particulate matter, can and will, remain in valves, pumps, motors and on the internal surfaces of high pressure hoses.  By introducing certain changes that greatly improve filtration system efficiency, equipment downtime can be significantly reduced because the fluid is purified and contaminates can be removed much more effectively than by a simple oil and filter change.

Studies and practical experience indicate that over 70% of hydraulic system failures occur within the hydraulic drive.  In turn, 50% of the hydraulic drive failures occur due to the presence of solid particles in the hydraulic fluid circulating in the system and the drive.  The high percentage of drive failures is due to the fact that hydraulic drive components rapidly wear down when operating with contaminated liquid.  This leads to a reduction of operating efficiency and an increase of internal energy loss.  Operational costs also rise all due to a lack of timely preventive maintenance.

If Serial Filters are used in the hydraulic system, the concentration of solids in the fluid will be approximately 0.022% by weight.  This is 4.4 times above the acceptable standard.  Particles from 10 to 40 micron in size can constitute up to 50% of the contaminants in the fluid.  These sizes mostly coincide with the clearances between friction surfaces and are therefore, the most dangerous and cause the most wear.

As with serial filters, Main Line Filters also cannot provide the required level of hydraulic fluid purification needed to prevent systems failures by themselves.   The hydraulic drive therefore, must be rinsed by special means or processes.

The importance of a thorough cleaning of the hydraulic drives is because of the high level of precision components found in hydraulic systems that are very sensitive to even small amounts of contamination.  As the system becomes larger, the rate of contamination also becomes larger increasing the need for timely preventive maintenance.

If the equipment is operated in dusty environments, particles of dust will settle on cylinder shafts and will enter the hydraulic drive.  A large portion of contaminates and wear products enter the hydraulic tank through the drain lines and cylinder shafts thereby avoiding the filter system.

A excellent way to improve and maintain the purity of hydraulic fluid is through periodic rinsing and removal of harmful particles.  GlobeCore’s UVR Purification Units are specially designed systems aimed at purification of turbine oil, industrial oil, and transformer oil and have a reputation for versatility and reliability.  They have the ability to purify oils and fluids back to their original new like condition and can even exceed well established quality standards.  The UVR plants, due to their compact design and high level of mobility, can be used at your maintenance facility or offsite at remote locations.  There are no restrictions that limit the use of the UVR systems anywhere there is a need for oil purification services.  The compact design allows GlobeCore to ship the UVR units to anywhere in the world.

While cleaning the system, it should be noted that special detergents can only be used in the beginning stages of the process since any detergent remaining is considered an unwanted contaminant.

Prevention of Contamination

Prevention of hydraulic system failures is only possible if enough attention is paid to the most likely cause of the failures.  It is generally accepted that contaminants are the leading cause of system failures. It is therefore, important to use effective methods of controlling and preventing contamination.  Controlling contamination can help to ensure efficient operation of the system, extend the service life of components, and eliminate malfunctions before costly repairs or unplanned down time is required.

Testing

A daily testing of the hydraulic system allows the operator to quickly localize leaks and other malfunctions before they impact operation.  Periodic checks include checking the pressure in the system, visual inspections, and checking fluid level before, during and after the completion of the work cycle.

Inside the Hydraulic System

Prevention of contamination is very important, but it is equally as important to understand the processes occurring inside the hydraulic system. Regular checking of hydraulic fluid is the best way of localizing part wear and contamination.

Regular sampling

In order to precisely estimate the condition of the hydraulic system, regular sampling of the fluid is required and recommended as part of a comprehensive preventive maintenance program.  It is recommended to take an oil sample for analysis every 500 hours of operation or sooner if the equipment is operated in extreme conditions.  If samples are taken regularly, a certain base line may be established and will allow the operator and maintenance manager to immediately see any deviations allowing for timely corrective action.
