Ventilation system and electric locomotive

Abstract

The invention relates to a ventilation system and an electric locomotive. The ventilation system comprises an air suction unit, an exhaust unit and a switch circuit, wherein the air suction unit comprises a first speed regulating fan and an air suction air passage, the air suction passage is communicated with an air inlet of the first speed reducing fan, the exhaust unit comprises a second speed regulating fan and an exhaust air passage, the exhaust air passage is communicated with an air outlet of the second speed regulating fan, and the switch circuit is connected with the first speed regulating fan and the second speed regulating fan and is used for controlling the first speed regulating fan and the second speed regulating fan to synchronously work. The ventilation system provided by the invention can be applied into a cab of the electric locomotive, fresh air can be supplemented into the cab, in addition, vitiated air can be synchronously exhausted, and the sufficient ventilation of the cab is realized.

Description

technical field [0001] The invention relates to ventilation technology, in particular to a ventilation system and an electric locomotive. Background technique [0002] At present, the cabs of electric locomotives are equipped with air-conditioning equipment. In order to ensure the effect of cooling and heating, the cabs are required to be well sealed, and the space in the cabs is small. fresh air. [0003] In the prior art, when the air in the cab is ventilated, an independent air supply system is usually used to supply fresh air to the cab, and an exhaust port is set for exhaust. However, because this exhaust method is natural exhaust, Moreover, the exhaust port is small, the exhaust resistance is large, and the intake of fresh air is usually large, the exhaust volume does not match the intake of fresh air, and the discharge capacity of dirty air in the cab is poor; A large difference in discharge will lead to an increase in the air pressure in the driver's room and affec...

Problems solved by technology

[0003] In the prior art, when the air in the cab is ventilated, an independent air supply system is usually used to supply fresh air to the cab, and an exhaust port is provided for exhausting. However, because this exhaust method is natural exhaust, Moreover, the exhaust port is small, the exhaust resistance is large, and the intake of fresh air is usually large, the exhaust volume and the intake of fresh air do not match, and the discharge capacity of dirty air in the cab is poor; The large difference in discharge will lead to an increase in the air pressure in the driver's room and affect the air quality in the driver's room

[0004] To sum up, when the existing cab is ventilated, the incoming fresh air does not match the exhausted dirty gas, resulting in insufficient ventilation, which affects the air quality in the cab and affects the driver's health
