Abstract

The invention discloses a control system for a water adding tank of an explosion-proof diesel engine. The control system for the water adding tank of the explosion-proof diesel engine comprises an exhaust manifold (1), a washing tank (2), the water adding tank (5) and an electronic control unit (ECU) (4). The exhaust manifold (1) is connected with the washing tank (2), and the water adding tank (5) adds water into the washing tank (2) through a pipeline. An electronic liquid level sensor (3) is arranged in the washing tank (2), and the ECU (4) is connected with the liquid level sensor (3) and an electromagnetic valve (6). The electronic liquid level sensor (3) is used for obtaining water level information of the washing tank (2), and the ECU (4) is used for controlling opening or closing of the electromagnetic valve (6) according to the water level information and a preset water level threshold value. By means of the control system, the tail gas disposal effect of the explosion-proof diesel engine is greatly improved.

Description

technical field [0001] The invention belongs to the field of explosion-proof diesel engines, and in particular relates to a control system for a water supply tank of an explosion-proof diesel engine. Background technique [0002] At present, mining transport vehicles powered by diesel engines need exhaust gas treatment. In order to keep the temperature of the diesel engine below 70°C, the exhaust gas of the diesel engine must be passed into the water washing tank. On the other hand, during the operation of the diesel engine, since the water in the washing tank is continuously taken out, the water level in the washing tank will become lower and lower, and when the water level in the washing tank is too low, the temperature of the diesel engine will drop. When the temperature exceeds 70°C, it is necessary to add another replenishing water tank, and fill the water in the replenishing water tank into the washing tank. At present, in the explosion-proof diesel engines of mining ...
