Description

Compact auxiliary compressor unit

Technical Field

The application relates to the field of compressors, in particular to a compact auxiliary compressor unit.

Background

The railway plays a very important role in modern logistics systems as an important infrastructure of the country, a development artery of national economy and a popular vehicle. The high-speed railway construction and the development of high-speed heavy-load high-power alternating-current electric locomotives are the key points of the modern development of railways, and in recent years, the high-speed railway construction in China is rapidly developed and is now the first country with the mileage of high-speed railways in the world.

An auxiliary compressor unit is needed to provide clean, clean and dry compressed air for a locomotive pantograph lifting system in advance in the running process of the electric locomotive so as to ensure the stable and reliable running of the electric locomotive, is a powerful guarantee for the reliable running of the electric locomotive, and is an indispensable component of a high-speed and heavy-load high-power alternating-current electric locomotive.

The compressor unit in the auxiliary compressor unit used on the domestic direct current transmission electric locomotive at present has the advantages of large volume, weight of more than 70 kilograms, large occupied space and incapability of meeting the use requirements of compact space and weight of the electric locomotive.

Disclosure of Invention

The present application provides a compact auxiliary compressor unit to solve the problems presented in the background art.

A compact auxiliary compressor unit comprises a shell, wherein an oil-free compressor, a cooler, an air inlet filter, a dryer, an overflow valve and a one-way valve are arranged in the shell, one end of the oil-free compressor is connected with the air inlet filter, the other end of the oil-free compressor is connected with one end of the cooler, the other end of the cooler is connected with one end of the dryer, the other end of the dryer is connected with one end of the overflow valve, and the other end of the overflow valve is connected with the one-way valve;

the dryer is a double-tower dryer. The double-tower dryer comprises two main functions of drying and regeneration, wherein the double towers of the double-tower dryer are used for drying one and regenerating the other, and the two towers are mutually switched after a period of time, so that the double-tower dryer can work circularly without special shutdown for drying recovery.

Preferably, a fine filter is arranged between the dryer and the overflow valve. For ensuring cleanliness, cleanliness and dryness of the compressed air.

Preferably, a safety valve is arranged between the dryer and the fine filter. To ensure safe use of the compressed air.

The application provides a compact auxiliary compressor unit has following beneficial effect:

1. the weight of the whole machine is less than or equal to 45 kg, and compared with the existing other auxiliary compressor units, the weight is reduced by 25 percent;

2. the double-tower dryer is adopted, so that the regeneration system of the auxiliary compressor continuously and alternately recovers the activity of the drying agent, and the efficiency of the auxiliary compressor is improved;

3. the oil-free compressor, the cooler and the dryer are integrated in the same shell, and compared with other existing auxiliary compressor units, the oil-free compressor, the cooler and the dryer are compact in structure and smaller in occupied space.

FIG. 2 is a top view of a compact auxiliary compressor package according to an embodiment of the present disclosure;

fig. 3 is a schematic connection diagram of a compact auxiliary compressor unit according to an embodiment of the present disclosure.

Wherein: 10-shell, 20-oil-free compressor, 30-cooler, 40-air inlet filter, 50-dryer, 501-drying tower, 60-overflow valve, 70-check valve, 80-fine filter and 90-safety valve.

Detailed Description

The technical solutions in the embodiments will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Referring to fig. 1 to 3, a compact auxiliary compressor unit includes a housing 10, an oil-free compressor 20, a cooler 30, an intake filter 40, a dryer 50, an overflow valve 60 and a check valve 70 are disposed inside the housing 10, one end of the oil-free compressor 20 is connected to the intake filter 40, the other end is connected to one end of the cooler 30, the other end of the cooler 30 is connected to one end of the dryer 50, the other end of the dryer 50 is connected to one end of the overflow valve 60, and the other end of the overflow valve 60 is connected to the check valve 70; the oil-free compressor 20, the cooler 30, the intake air filter 40, the dryer 50, the relief valve 60, and the check valve 70 are all integrated in the same housing 10.

Specifically, the dryer 50 is a double tower dryer consisting of two drying towers 501. The double-tower dryer comprises two main functions of drying and regeneration, and is essentially different from the single-tower dryer used in the prior art in that the single-tower dryer can only be shut down after being operated for a period of time, and drying recovery is carried out by using the drying air in the regeneration air cylinder, while the double-tower dryer can be operated all the time because the double-tower dryer is regenerated and recovered when in operation and does not need special shutdown and recovery. The double towers of the double tower dryer are switched each other when one is dry and the other is regenerated after a period of time, thus the cycle work can be realized, the activity of the dryer 50 can be recovered, and the service life of the dryer 50 can be prolonged.

Referring to fig. 1 to 3, a fine filter 80 is provided between the dryer 50 and the relief valve 60 to ensure the compressed air to be clean, clean and dry; a safety valve 90 is provided between the dryer 50 and the fine filter 80 to ensure safe use of the compressed air.

When the compact auxiliary compressor unit provided by the application works, the oil-free compressor 20 works to compress air to a required exhaust pressure; the compressed air with increased pressure enters a dryer 50 for drying after being cooled by a cooler 30; the dried compressed air passes through the fine filter 80, the overflow valve 60 and finally the check valve 70 for the locomotive air system.

Other embodiments of the present application will be apparent to those skilled in the art from consideration of the specification and practice of the application disclosed herein. This application is intended to cover any variations, uses, or adaptations of the invention following, in general, the principles of the application and including such departures from the present disclosure as come within known or customary practice within the art to which the invention pertains.
