Using Oil Filtration Equipment From America to the Arctic

Oil filtration equipment removes contaminants from transformer oil, including water, particulate matter, air and other gases. Such systems commonly employ high vacuum and heat for oil treatment.

Oil filtration equipment is connected to the power transformers and the contaminated oil is supplied into the purification unit by pumps.Most of the filters used in such equipment can remove solid particles as small as 1 micron. To remove other contaminants, the oil is heated and passes through a vacuum chamber, where gas and water are removed from the surface of the oil.

The available range of oil processing equipment includes comprehensive systems, which are capable of performing multiple purification tasks.These units are used for preparation of fresh fluid for use in power systems, regeneration of transformer oil for further use and servicing of the power distribution facility in general.

Fresh oil must comply with purity and and quality standards, so it is degassed, dehydrated and filtered before being used in power systems.

If the oil already in use ages and demonstrates low flashpoint, high ash content, high cloud point, high dissipation factor, high acidity and low dielectric strength, the oil should be thoroughly  regenerated.

Since disposal of old oil and buying new oil are costly affairs, using the available equipment to purify oil and extract the sediment from the windings of the transformer is a very viable option, which saves on many costs, including the cost of repairing or even replacing a failed transformer.

Oil purification equipment is built for operation in various environments and climates. Stability and processing capacity of the machinery in high or low ambient temperatures, atmospheric pressure and elevation above sea level, makes the equipment usable by many clients the world over.

Bypass Oil Filtration: A Workaround?

Most users rarely think of the capabilities and difficulties of the equipment at their disposal.

This is equally true for regular consumers and large industrial users with large parks of various machinery and equipment.

This article focuses of bypass oil filters.

Filtration equipment of various models purifies and restores the quality of various fluids.

A reliable comprehensive purification system extends the service life of the oil and of the equipment the oil is used in.

The main components of such systems are vacuum chambers or adsorption columns, along with coarse and fine filters.

There are two types of fine filters: full-flow or bypass. The difference is that a full-flow filter takes the entire liquid flow, while a bypass filter is installed into the system in parallel and only takes 10% of the purified oil.

So, what do we know about oil filters, their capabilities and design? How does filter design influence filter efficiency?

Oil filters are used extensively for purification of motor, transmission, lube, hydraulic, turbine, transformer and other types of oil. The oil filter is an essential part of an automobile engine. First engine oil filters were quite simple, no more than a screen before the oil pump.

The first bypass filter was developed by American engineers in the beginning of the previous century. Most of the oil was supplied to the engine, while some oil was sent to the filter in parallel. With time, all oil was filtered. Oil from the filter returned to the sump.

Pure bypass filtration systems are not very common in the market, since such filter only processes 10-20% of oil circulating in the engine. However, the filtering media are usually rather effective in removing the smallest contaminant particles.

Actually, combined use of full-flow and bypass oil filters extend oil change intervals. This is because most of the oil is filtered by the full-flow filter, while the bypass filter removes the fine particles. As a result, the full-flow filter does not clog as fast.

Double-stream filters are also quite popular. These are designed around combining a full-filter and a bypass filter in one container. In such container, oil is divided in two streams, one of which goes through to the motor, while the other passes through a fine filter and goes back.

While looking for the optimal solution, the client should not only research all offers carefully, but also, maybe, participate in trials of such filtration systems and compare the efficiency of various filter solutions. There are many systems to chose from, bypass filter being only one of them.
