Problems solved by technology

When the lubricating oil is emulsified, the surface of the screw will not be able to form a covering oil film, resulting in the wear of the screw profile, resulting in problems such as low exhaust volume and long blowing time; further development will cause the bearing of the screw group to wear due to lack of oil, causing the machine head to hold Dead burning damages the motor, endangering driving safety

Abstract

The invention provides a train wind source system and lubricating oil emulsification prevention method. A first valve and a second valve are adopted for switching backflow branches with different displacements to carry out grading adjustment on flow of compressed air flowing through a drying tower, thus the final displacement of a wind source system is adjusted, and at the premise of meeting the requirement for normal wind use of a train, the wind source system has a large displacement during the passenger peak season and the vehicle starting initial wind supplementing stage, and has a relatively small displacement during the normal operation period or other working conditions with few passengers. The system and the method have the final effect that the wind source system always maintainsa high operation rate during the train operation period, and therefore the problem of emulsification of lubricating oil of the system is solved.

Description

technical field [0001] The invention relates to the field of rail transportation, and more specifically, to a train air source system and a method for preventing and controlling lubricating oil emulsification. Background technique [0002] The air source system of a rail transit vehicle is an equipment device that provides compressed air for the train, and the compressed air it provides ensures the normal operation of the train braking system and bogie system. The air source system consists of compressor head, safety valve, dryer and precision filter. Due to its high mechanical reliability and excellent dynamic balance, the screw air compressor can continuously output high-flow compressed air without pulsation, and is very convenient to operate and maintain. It is widely used in the air source system of rail vehicles. [0003] The air compression of the screw air compressor is achieved by the volume change of the tooth slots of the male and female rotors that are installed ...
