Embodiment Construction

[0015] According to the technical solution of the present invention, the present invention adopts a closed circulating water system to separate the high and low temperature water systems of the diesel engine, and the independent high and low temperature circulating water systems are composed of water tanks, plate coolers, and cooling towers. The process of implementing the cooling water treatment of the diesel engine test run is as follows: firstly, the cooling water circulation system of the diesel engine is washed and pre-filmed to ensure the cleanliness of the cooling water circulation system. Be prepared for the addition of cooling water corrosion inhibitors.

[0016] Add the cooling water corrosion inhibitor provided by Nanjing Ocean Shipping Supply Co., Ltd. to the water tank of the diesel engine cooling water circulation system, according to the requirements for the first use of the water treatment agent: water = 1 (liter): 80 (liter). Measure and control the pH value o...

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 [0001] The invention relates to the treatment of a circulating cooling water system of a diesel engine test stand, in particular to a treatment method of a circulating cooling water system of a diesel engine test stand. Background technique [0002] At present, domestic diesel engine manufacturers generally do not treat the circulating water used in the bench test of the diesel engine, and the diesel engine generally adopts an open circulation system during the bench test, resulting in rust and corrosion of the parts of the diesel engine after the bench test of the diesel engine. Scaling phenomenon will affect the reliable operation of the diesel engine in the future. Contents of the invention [0003] In order to overcome the above-mentioned difficulties, the present invention provides a process for treating the cooling water of the diesel engine test run, which solves the problems of rust and fouling after the diesel engine bench test. [0004] The solut...
