1. Stands for liquids cleaning SOG

Purpose

Centrifugal fine cleaning of industrial and energy oils, liquid coolants, hydrosystems working liquids, diesel fuel and kerosene from mechanical impurity and water. The stands are made on SOG base model 913K1M (all models have certificates of conformity)

Description

By cleaning fineness the SOG stands correspond to 5-micron aviation filters. They enable to separate undissolved water.

In comparison with cartridge systems for similar purpose the SOG stands are distinguished by high economy in operation owing to higher mud absorbing capacity (10 kg) - several grams with filters - and absence of replaceable filtering elements.

High efficiency, low dimensions, mobility and easy operation of the stands make it possible with high quality and minimal costs to service different equipment immediately at site:
aircraft construction, motor and air-engine enterprises
cleaning of working liquids, test beds, process equipment, plane and helicopter hydrosystems;
machine and machine-tool plants, repair shops
providing cleanliness of hydraulic systems of machine tools, presses, automatic lines, foundry machines, as well as removal of processing products from liquid coolants on oil and water base;
power supply enterprises cleaning of turbines and pumps oils, as well as in vacuum and adsorption installations for transformer oils regeneration as a preliminary stage for cleaning from undissolved water and mechanical impurities;
gas- and oil-pumping stations
oils cleaning in lubrication systems of gas-and oil-pumping units;
railway transport enterprises
periodic oils cleaning of hydraulic systems of track-repair machines, machine tools for processing of wheel pairs, removal of water and mechanical impurities from motor oils;
service stations of automotive, road and construction technical equipment
refueling-in and periodic cleaning of hydrosystem oils of tractors, dredges.

Principle of operation

Smallest firm and liquid contamination particles are deposited on surface of a centrifuge-pump rotor equipped with spiral or disc insert as result of its rotation of with very high speed. (One pass of liquid through the stand allows to reduce the concentration of contamination particles by hundreds times).

After centrifuge stopping liquid impurities flow down from the rotor in a settling tank, firm impurities are directed in a mud collecting vessel.
Stands with a system of continuous water drainage from the centrifuge rotor are used if fuel and oil contain a lot of water.

2. Restoration of transformer oils. Facilities for restoration of transformer oils UVM

Purpose

Cleaning of transformer oils from mechanical impurities, acids and water at refueling-in and operation of oil-filled equipment. They are promising for use in power sites of different enterprises.

Description

UVM facilities provide:

- Increase of transformer oil breakdown voltage to 70 кV;
- Acidity reduction by 10 times;
- Oil heating to +70оС.

Process of cleaning includes centrifugal and adsorption stages that enables to increase efficiency of equipment operation and significantly (by dozens of times) to prolong service life of the adsorbents (practically no regeneration is needed).

Models produced

Models produced: UVM-01 (a centrifugal cleaning unit + an absorption cleaning unit), UVM-03 (an oil-heating unit + a centrifugal cleaning unit + an absorption cleaning unit).

The centrifugal cleaning unit.

Due to that one of models of SOG stands is included in a structure of the unit, UVM facilities can be used for cleaning of highly polluted oils, providing substantial increase of a adsorbents resource.

At UVM productivity of 900 l/hour to 80% of total water (dissolved and emulsive) is removed from oil for one pass, and the rest water is adsorbed by zeolite (absorption cleaning unit), providing output water content of 10-20 g/t. (At typical initial watering of 100g/t adsorbents resource is enough for treatment of not less than 200 t of transformer oil).

The SOG stand operate in the facility as a pump to supply oil through adsorbers.
The adsorption cleaning unit.

It includes eight adsorbers, containing cartridges with zeolite (water removal) and silica gel (removal of acid, oxidation products and water).

A single-stage or a repeated (circulating) cleaning method is used depending on oil pollution level.
The oil-heating unit.

The oil-heating unit. It provides optimum oil temperature (50оС) for cleaning by adsorbents of both types. Oil heating is carried out for one pass. The unit can be used as an independent module for heating and pumping of mineral oils in warehouse and shop conditions.

3. UPOM facility: used oil into diesel fuel

Transformation of used oils in diesel and other kinds of fuel.
The method enables:

- to obtain an additional volume of good-quality diesel fuel corresponding to GOST standard and not worsening engine operation (it is confirmed by results of laboratory tests);
- to save on expenditures for recycling used oils and to improve ecological situation in an object.

Preliminary cleaned used oil (no more than 5-7%) is mixed with diesel fuel with the subsequent two-stage cleaning of obtained mixture in "thin-walled" centrifuges (SOG).

Facility is promising for operating in sea and river ports, enterprises using heavy vehicles, railway.

In Russia there are no analogues. The cost of UOMM facility is $20.0 thousands (the cost of the American-Canadian "Wotec" analogue is $320.0 - 400.0 thousands at more expensive maintenance service).

Cooperation proposals:

- Industrial tests of UOMM facilities at a Customer's enterprise with drawing up of the Contract or the Agreement for the test period without financial obligations.

- Decision-making about commercialization of the Contract (Agreement) on base of tests results.

As a rule, in the world equipment with expensive replaceable filtering cartridge elements is used for cleaning used oil.

The alternative technology on base of centrifugal cleaning principle (with the use of a centrifuge) is cheaper and more effective.

The data on firms using technology of centrifugal cleaning is presented below.

4. Proportioning pumps

JSC

Purpose


Pressure proportioning of different liquids (inert, toxic, aggressive) in heat-and-power engineering, oil-production and other industries.

Description

The pumps feature a fundamentally new highly effective design of the power drive based on a linear electromagnetic motor (there is no reduction gear and mechanism for rotation conversion into reciprocating motion). It enables notably improve reliability and efficiency of the device operation.

The microprocessor control system with automatic overload protection in the hydraulic system enables to realize smooth regulation of the pump capacity, manual and automatic control in digital or analogous modes.
