The invention relates to the technical field of pump box unit design, in particular to a motor
train unit pump box
unit device. The device comprises a box body and a water pump arranged in the box body, the inner wall of the box body is provided with a heat preservation material, the upper part of the water pump is provided with a
pressure switch, the bottom of the
pressure switch is connected with the water outlet
pipe, a second
junction box is arranged in the box body, a
transmitter and a
relay are arranged in the second
junction box, the bottom of the water pump is connected with a manual
ball valve through a tee joint, the outer side of the manual
ball valve is connected with an
electromagnetic valve, and the bottom of the
electromagnetic valve is connected with a drain
pipe. The device further discloses a manufacturing method of the motor
train unit pump box
unit device, according to the motor
train unit pump box
unit device, parts inside the box body can be isolated and protectedthrough the heat preservation material, external low-temperature gas is prevented from entering the device, the water pump and the
water supply can be carried out in winter through the heat tracing device, the normal work of the drainage pipeline is effectively protected and guaranteed, and the phenomenon that the
icing phenomenon occurs when the temperature is low is avoided.
