Problems solved by technology
[0002] The water supply pipelines of rail vehicles, especially railway passenger cars, mostly use water pumps to provide pressurized water. When the water pumps work, noise will be generated, which will reduce the comfort of passengers.
[0003] In the prior art, in order to reduce the impact of noise on passengers, the water pump is mostly installed on the top of the vehicle roof, and an inspection door is set on the roof. It is inconvenient to operate the water pump from the inspection door.

The invention discloses a water pump box for a rail vehicle and a rail vehicle. The water pump box includes a box body and a water pump arranged in the box body; the box body is provided with a support plate for supporting the water pump and a The fixing seat for fixing the support plate; at least one first elastic mounting seat for reducing the lateral vibration of the water pump is arranged between the support plate and the fixing seat; and / or the water pump and the support plate are provided There is at least one second elastic mount for reducing longitudinal vibration of the water pump. In the present invention, by setting the first elastic mounting seat between the support plate and the mounting seat and / or the second elastic mounting seat between the water pump and the support plate, the water pump can be smaller in the horizontal direction and / or in the up and down direction during operation. The movement of the amplitude can reduce the noise generated by the vibration when the water pump is running, so that the water pump box of the present invention is not limited by the installation position, and it will not affect the passengers in the compartment when it is installed at a position that is convenient for maintenance personnel.
Description
technical field [0001] The invention belongs to the technical field of rail transit equipment, in particular to a water pump box for rail vehicles and the rail vehicles. Background technique [0002] The water supply pipelines of rail vehicles, especially railway passenger cars, mostly use water pumps to provide pressurized water. When the water pumps work, noise will be generated, which will reduce the comfort of passengers. [0003] In the prior art, in order to reduce the impact of noise on passengers, the water pump is mostly installed on the top of the vehicle roof, and an inspection door is set on the roof. It is inconvenient to operate the water pump from the inspection door. [0004] In view of this, the present invention is proposed. Contents of the invention [0005] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a water pump box for rail vehicles capable of anti-vibration and noise reduct...
