Output pressure stabilizing air compressor with pressure boosting nozzle

Abstract

The invention discloses an output pressure stabilizing air compressor with a pressure boosting nozzle, and relates to the technical field of air compressors. An electromotor supporting seat is connected with an air compressor electromotor; the air compressor electromotor is connected with an air compressor body; the air compressor body is connected with an air inlet pipe; the air inlet pipe is connected with an air nozzle; the air compressor body is connected with an output pipe; the air nozzle is connected with an air filter; a pressure sensor is mounted on the output pipe; a center control is mounted on the air compressor electromotor; a conical dust cap is mounted at the top of the air filter; an air guide baffle and an oil film filter screen are connected to the lower part of the dust cap; the air guide baffle and the oil film filter screen are cylindrical; an oil can is mounted below the air filter, and is upwardly opened and cylindrical; the diameter of the air guide baffle is less than that of the oil can and greater than that of the oil film filter screen; the air nozzle is in the shape of a fusiform horn of which the outer end is small and the inner end is gradually enlarged.

Description

technical field [0001] The utility model relates to an air compressor with a boost air intake nozzle and a stable output pressure with a boost air intake nozzle, which relates to the technical field of air compressors. Background technique [0002] my country's railway network spreads all over the country, and railway passenger transport is the mainstream means of transportation. [0003] During my country's railway operation, at 4:41 on April 28, 2008, the downlink Beijing-Qingdao passenger train T195 derailed between Wangcun and Zhoucun on the Jiaoji Line and rushed to the outside of the uplink base. At this time, the normal operation of the 5034 passenger train from Yantai to Xuzhou failed to brake enough, and finally collided with the derailed vehicle at a speed of 70 kilometers per hour, and the locomotive and the 1st to 5th carriages derailed. The Jiaoji railway train collision accident has caused 72 deaths and 416 injuries. [0004] Therefore, the train braking resp...

AI Technical Summary

Problems solved by technology

[0007] But, the deficiency of this brake machine of prior art is: when the train is running normally, the filling or exhausting of the brake main pipe is controlled by the locomotive, and when the brake main pipe is filled with wind, the compressed air will be distributed through each vehicle. Valves / control valves flow to the service and auxiliary cylinders for this vehicle

However, since each vehicle is only controlled by electric signals when the electropneumatic brake is charged, the wind source required in the charging process is still provided by the locomotive.

Even under the control of electric signals, the auxiliary air cylinder and the active air cylinder of each vehicle can start to inflate air almost at the same time, but the total air volume has not been reduced, and the air inflating time still cannot be effectively shortened.

[0013] It can be seen that no matter whether it is an automatic air brake or an electro-pneumatic brake, after a relief, the pressure in the auxiliary air cylinder fails to return to the standard value in a short period of time, and the brake cannot be applied when braking is required. Cylinders provide enough compressed air that the brakes don't produce enough braking force, or even no braking effect at all
