The original machine type adopts a motor to accelerate and drive the impeller through a gear box, and has great limitation when in use. Large volume, difficult installation and high cost.
SUMMERY OF THE UTILITY MODEL
The utility model discloses it is too big to current centrifugal compressor volume, difficult installation, defect such as cost height adopts centrifugal compressor to add permanent-magnet machine and turbo expander structure in an organic whole to reach small, the purpose that the cost is low.
In order to achieve the above purpose, the present invention adopts the following technical solution.
A centrifugal compressor directly driven by diesel oil comprises a first base shell, a base body and a second base shell, wherein the first base shell, the base body and the second base shell are sequentially connected; a first accommodating space is arranged in the first base shell, and a centrifugal compressor is arranged in the first accommodating space; a second accommodating space is arranged in the second base shell, and a turbine expander is arranged in the second accommodating space; a third accommodating space is arranged in the base body, a permanent magnet motor and a shaft penetrating through the permanent magnet motor are arranged in the third accommodating space, and two ends of the shaft are respectively connected with the centrifugal compressor and the turboexpander; the second accommodating space also comprises a diesel combustion chamber.
Furthermore, the diesel combustion chamber is provided with a diesel inlet for spraying atomized diesel into the compression cavity diesel combustion chamber.
Furthermore, a power supply structure is arranged on the base body and used for supplying power to the permanent magnet motor.
Further, the first base shell, the base body and the second base shell are made of cast aluminum shells.
Compared with the prior art, the utility model, following beneficial effect has at least.
The utility model relates to a do not use diesel engine as power, but directly use diesel oil in the inside burning of centrifugal compressor as the technique of power, in the use, because of having removed diesel engine, also need not acceleration gear, so the volume is very little, is convenient for install and provides power use on various integration equipment. Because no wearing part is arranged, the problem of service life limitation of the diesel engine is solved.
The application does not use a diesel engine as power, but directly uses diesel oil to be combusted inside a centrifugal compressor as power. In the using process, the diesel engine is removed, and the speed increasing gear is not needed, so the size is very small, and the device is convenient to be arranged on various integrated devices to provide power for use. Because no wearing part is arranged, the problem of service life limitation of the diesel engine is solved.
And, the utility model overcomes current centrifugal compressor is bulky, difficult installation, and defects such as cost height adopt centrifugal compressor to add permanent-magnet machine and turbo expander structure in an organic whole to realize small, easily install, advantage such as cost low. And can also realize the dual energy conversion of electric power and diesel oil, so in the use, the practicality is very strong, can use electric drive, can use diesel oil drive again, convenient good usefulness.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to the attached drawings, the application discloses a centrifugal compressor directly driven by diesel oil, wherein a turbo expander is added on the basis of the original centrifugal compressor to serve as a driving machine, a permanent magnet motor serves as a starting machine, the centrifugal compressor rotates at a high speed, atomized diesel oil is sprayed into a compression cavity, high-pressure air is sprayed into fuel oil to generate deflagration, the gas expands rapidly and is discharged through the turbo expander, and therefore high-speed operation is achieved, and redundant gas generated by the centrifugal compressor is used as gas energy of a user side.
The centrifugal compressor directly driven by diesel oil comprises a first base shell 1, a base body 3 and a second base shell 9, wherein the first base shell 1, the base body 3 and the second base shell 9 are sequentially connected; a first accommodating space is arranged in the first base shell 1, and a centrifugal compressor 2 is arranged in the first accommodating space; a second accommodating space is arranged in the second base shell 9, and a turbo expander 6 is arranged in the second accommodating space; a third accommodating space is arranged in the base body 3, a permanent magnet motor 4 and a shaft 5 penetrating through the permanent magnet motor 4 are arranged in the third accommodating space, and two ends of the shaft 5 are respectively connected with the centrifugal compressor 2 and the turboexpander 6; the base body 3 is provided with a power supply structure 10 for supplying power to the permanent magnet motor 4. The second accommodating space also comprises a diesel combustion chamber 7. The diesel combustion chamber 7 is provided with a diesel inlet 8 for spraying atomized diesel into the compression cavity diesel combustion chamber 7. In the design, a cast aluminum casing, a cast aluminum impeller and the like are adopted.
This centrifugal compressor of diesel oil direct drive utilizes permanent-magnet machine 4 as the starter, starts, makes centrifugal compressor 2 rotate at a high speed, spouts vaporific diesel oil in compression cavity diesel oil combustion chamber 7, because of high-pressure air spout the fuel after, can produce the detonation, gaseous emergence expands rapidly, discharges through turbo expander 6 to realized high-speed operation, the unnecessary gas that centrifugal compressor 2 produced, as the gas energy of user.
