Description
Technical Field
The utility model belongs to the technical field of engine water cooling system maintenance system and specifically relates to an engine water cooling system's operation processing apparatus.
Background
The water cooling system of the engine (the water cooling system of the engine is commonly known as the whole cooling liquid circulating system of the water-cooled engine, the whole system is composed of key parts such as the engine (comprising a water pump), a water pipe, a radiator and the like, wherein the cooling liquid is forcibly circulated in the system to realize the transmission and the heat dissipation of the redundant heat of the engine) is a totally-sealed forced circulating system, and the water pump of the engine provides circulating power for the whole system. The engine water cooling system is in large and small circulation: the control is realized by an engine thermostat, the cooling liquid circulates in the engine during small circulation, and a cooling liquid circulating path is 'engine-radiator-engine' during large circulation of the engine.
To prevent air from entering the system and causing corrosion or low temperature boiling of the coolant due to insufficient system pressure (the boiling point of the coolant in high altitude areas decreases with increasing altitude), it is common for the system to be in a fully sealed form. The conventional water cooling system comprises a fully-sealed upper water chamber type system and a secondary water tank type system, and the structure of the secondary water tank type system is shown in figure 2. The common water cooling system of the engine can meet the use requirement of full-sealed forced circulation. The numbers in the figure are specified as follows: 1-engine, 2-degassing pipe, 3-water outlet pipe, 4-auxiliary water tank, 5-degassing pipe, 6-water radiator and 7-water inlet pipe.
Once the leakage condition occurs in the common engine water cooling system, the requirement of full-sealed forced circulation cannot be met. Even if the leak point occurs at a low position of the entire system (e.g., at the piece 7 in fig. 2), serious troubles such as high temperature of the engine due to a large amount of leakage of the coolant may occur.
In order to solve the problem of leakage of the cooling liquid, engineers have taken some measures to avoid the leakage. Two are commonly used:
1. a transparent observation window is added at a proper position of the water radiator, and the quantity of the cooling liquid and whether leakage exists are judged by observing the liquid level of the cooling system before or after the equipment runs or stops.
2. When the cooling system is in operation, the vehicle will alarm to stop or reduce the load once the leakage level of the system is lower than a certain limit value.
The two methods have certain positive effects, but have obvious limitations and defects. The method 1 must be used during parking, cannot be applied in the operation process of equipment, and cannot judge the leakage point of the cooling system and carry out emergency treatment. Method 2 can be used when the equipment is running, but the leakage point of the cooling system cannot be judged and emergency disposal is carried out.
