Oil coolers series МП

Oil coolers series МП are meant for the construction of the oil cooling system.

Oil coolers are manufactured in climatic versions of УХЛ and O, the category of placing is 3 or 4 according to GOST 15150-69.

Oil coolers МП consist of a body, upper and lower water chambers, and of a pipe system.

The tube system (tube bundle) of a thin-walled stainless steel tube (non-circular tube) is expanded in two tubes, partitions and casings. As a result, the coolant's resistance to corrosion effects increases very much, without affecting the intensity of heat transfer. The flow rate of the liquid in non-circular tube is up to 10 times higher than in the smooth tube. The dynamics of the flow of liquid and the process of heat exchange is preserved along the entire length of the transversely profiled tube.

Principle of operation and construction of oil coolers series MP:

The cooling water is fed through the branch input tube under the pressure to the lower water chamber, from which, countercurrent to the oil it goes along the tubes to the upper one, after which it returns to the lower one through the return tubes. From the lower water chamber, water goes through the outlet tube. On this chamber there are hatches for cleaning it. On the body there are oil inlet and outlet tubes. On the upper water chamber there is a crane for air discharge, on the body - nipples for flushing the heat exchange tubes.

Technical characteristics, overall and mounting dimensions of oil coolers are agreed by order.

Basic standarts of water:

Characteristics Sort of water and reference designation
Fresh water Mineralized water Sea water
ПВ МВ1 МВ2 МВ3 МВ4 МВ5 МВ6 МВ7 МВ8
Reference designation of cooler version depending on sort of cooling water
Н М М2 М5, СМ
Salt content
in water, mg/l
0…300 300…1500 1500…3000 3000…5000 5000…15000 >15000
Type of contamination runoff, mg/l ≤1 - ≤1 -
suspensions,

- ≤23 ?50 - ≤25 - Abrasive contaminants
≤25
-

Note:
Runoff – total content of ammonia, hydrogen sulfides, nitrites etc.
Suspensions – fractions of mineral and organic origin (mechanical impurities).
For water МВ2, МВ3, МВ4, МВ5 – content of chlorides has not to be more than 2000 mg/l regardless of the total salt content.

 

 

Climatic versions and category of placing:

 

 

УXЛ- for macroclimate areas with moderate and frigid climate.

Т - for all macroclimate areas overland, except the macroclimate area with very frigid climate (general climatic version).
- for use in spaces (contents) with artificial regulation of climatic conditions (in enclosed heated or cooled spaces).

 Reference designation of cooler type by order:

МП-65-Н-УХЛ4, (ТКЛУ.065179.205), ТУ 3113-002-76242415-2015, where:

МП –series of oil cooler;
65 - heat exchange surface m2
Н - cooler version depending on the characteristics of the cooling water;
УХЛ - climatic version according to GOST 15150-69;
4 - category of placing according to GOST 15150-69;
ТКЛУ.065179.205 - designation of main engineering document.

Example of product recording by export deliveries to the countries with moderate climate:
МП-65-Н-УХЛ4 эксп., (ТКЛУ.065179.205-02), ТУ 3113-002-76242415-2015.

Example of product recording by export deliveries to the countries with tropical climate:
МП-65-Н-Т4 эксп, (ТКЛУ.065179.205-04), ТУ 3113-002-76242415-2015.

 

Besides above-listed types of the oil coolers, we design and produce the oil coolers by specification of the customer.
