Wind source system of electric locomotive

Abstract

Disclosed is a wind source system of an electric locomotive characterized in that an air compressor is respectively connected with a main air reservoir pipeline and a pressure measuring pipeline through a main air pipe, the pressure measuring pipeline comprises a first steel pipe, a second steel pipe, a connector and a pressure gauge, one end of the first steel pipe is connected with the main air pipe, and the other end of the first steel pipe is connected with the first end of the connector; one end of the second steel pipe is connected with the pressure gauge, and the other end is connected with the second end of the connector; the first end of the connecting joint is provided with a first inserting hole for the first steel pipe to be inserted, the second end of the connecting joint is provided with a second inserting hole for the second steel pipe to be inserted, the connecting joint is internally provided with a straight-through channel communicated with the first inserting hole and the second inserting hole, and the diameter of the straight-through channel is 1 mm or 1.5 mm. According to the wind pressure pipeline, the problem that a pressure gauge shakes seriously can be thoroughly solved, particularly, the connecting joint is arranged at the tail end of the pipeline, and airflow pulsation in the air pipeline can be eliminated through limitation of the diameter of the straight-through channel in the connecting joint.

Description

technical field [0001] The invention relates to electric locomotive accessories, in particular to an electric locomotive wind source system. Background technique [0002] The air source system of HXD3D electric locomotive mainly includes the main air source system composed of air compressor unit, double-tower air dryer, main air cylinder, etc., and the auxiliary compressor, auxiliary dryer, regeneration air cylinder, lifting bow control module, There are two parts of the auxiliary air source system composed of bow-raising air cylinder and so on. [0003] The air compressor unit has two screw-shaped rotors, and there is almost no fluctuation in the compressed air delivery, but in fact, during the operation of the rotor, because the suction and exhaust are intermittent, the two alternately, making the air flow in the pipeline pulsating . The specific performance is that the main air cylinder MR (red) of the two-needle pressure gauge in the driver's cab vibrates seriously. T...
