Abstract
The invention relates to the bench test circulating cooling system for diesel engine. It is an enclosed system with separated high and low temperature water system, the former composed of water tank, water pump, water separator, diesel engine, return water collector, plate cooler, and the latter composed of low temperature water pool, water pump, water separator, cooling tower, to form the high and low temperature circulation water system. It avoids the pollution of rain and microbiology of the water circulation system.The coolant corrosion inhibitor is made of water treatment agent: water=1:100(l). The PH value of the coolant is kept between 8.3-10, better solved rust and deposition issue of the components, ensured reliability of the diesel engine.
Description
Technical field
The present invention relates to the processing of diesel engine test bay bench test recirculating cooling water system, the disposal route of refering in particular to a kind of diesel engine bench recirculating cooling water system.
Background technology
Because domestic diesel engine manufacturing plant does not generally deal with recirculated water in bench test diesel engine at present, diesel engine generally all adopts open-cycle system in the bench test process, caused the parts of diesel engine to produce corrosion and scale formation, influenced the later reliability service of diesel engine in diesel engine bench test back.
Summary of the invention
In order to overcome above-mentioned difficulties, the invention provides a kind of process of diesel engine test run cold water process, solve diesel engine bench test back and produced corrosion and scale problems.
The present invention solves the problems of the technologies described above the scheme that is adopted:
1. cooling water system adopts closed circle water system, and the high-low-temperature system of diesel engine is separated, and forms the high-temperature internal circulation successively by water tank, water pump, water trap, diesel engine, backwater water collector, panel cooler; Low temperature pond, water pump, water trap, cooling tower have been formed respectively independently low temperature outer loop water system successively in addition, the common warm closed circle water system of height of forming.Thereby overcome the problem that the open circulation water system may be subjected to rainwater and contamination by micro.
2. use or cooling water system is subjected under the situation that oil and incrustation scale pollute when cooling water system is first, before adding the cooling water corrosion inhibitor, the reply water system carries out necessary prerinse, removal greasy dirt, foundry loam, incrustation scale etc.
3. the interpolation of cooling water corrosion inhibitor: at diesel coolant circulation system interpolation cooling water corrosion inhibitor in the water tank, adding proportion is: water treatment agent: water=1 (liter): 100 (liters), described cooling water corrosion inhibitor are that nitrite/borate is that the basis contains organic corrosion inhibitor compound.The chilled water pH value of Control Circulation water system does not reach requirement can add 50ml in recirculated water per ton alkaline controlling agent Unitor AlkatinityControl as pH value between 8.3-10.
When 4. using first, can suitably improve the concentration for the treatment of agent, proportioning can be risen to: water treatment agent: water=1 (liter): 80 (liters) in order to ensure result of use.In the diesel engine process of the test, the recirculated cooling water pressure that diesel engine is advanced in control remains on 0.1-0.3MPa.
5. before bench test, produce corrosion for fear of parts and components of diesel engine, in the water tank of the hydraulic testing operation hydraulic testing, also add the cooling water corrosion inhibitor in proportion.
Advantage of the present invention is:
(1) at diesel engine bench test back parts corrosion and scale formation, after the process of employing diesel engine test run cold water process, solved diesel engine bench test back parts corrosion and scale formation well, guaranteed the reliability that diesel engine uses.
(2) diesel coolant outer loop water, adopt high-low-temperature separately after, avoided circulation may be subjected to rainwater and contamination by micro.

Embodiment
According to technical scheme of the present invention, the present invention takes closed circle water system, and the high-low-temperature system of diesel engine is separated, and has formed independently high low temperature circulation respectively by water tank, panel cooler, cooling tower etc.The technology of implementing diesel engine test run cold water process is: at first the diesel coolant circulation system has been carried out the pre-film of flushing, guaranteed the cleaning of cooling water recirculation system.For the interpolation of cooling water corrosion inhibitor is got ready.
Add the cooling water corrosion inhibitor that Nanjing Ocean Shipping Supply Company provides in the diesel coolant circulation system in water tank, by the first requirement of using of water treatment agent: water=1 (liter): the interpolation of 80 (liter) ratio.The chilled water pH value of measuring the Control Circulation water system meets the requirements at 8.3-10.The diesel engine operation guarantees that circulating water pressure remains on 0.1-0.3MPa.
