Problems solved by technology

[0002] During the use of a certain type of engine pressure ratio regulator in the field, affected by technology and climatic conditions, frequent failures occurred
At present, there is no such precise adjustment tool in this field. The traditional adjustment method is affected by the operating space. Relying on general-purpose tools, there are safety hazards in the adjustment process. It is difficult to operate and cannot accurately control and record the adjustment amount based on visual estimation of the adjustment amount.
Long test run time, high fuel consumption and equipment loss

Embodiment 1

[0030] Such as figure 1 As shown, a through hole is provided on the peripheral surface of the front end of the transmission shaft 2, and the operating handle 1 is cylindrical, which is in interference fit with the through hole to facilitate rotation; the end of the transmission shaft 2 is provided with a sleeve 6, and the sleeve 6 is a universal joint. The sleeve can adapt to various adjustment positions and adjustment angles, and can avoid the intricate external circuits, pipelines and brackets. The inner diameter of the sleeve 6 is the same as the outer diameter of the adjustment part. Ventilation holes 7 are provided. When the adjustment part is exhausted, the gas is discharged from the gap of the sleeve 6 along the ventilation holes 7. Therefore, the adjustment does not interfere with the normal exhaust of the adjustment parts and does not affect the normal operation of the engine; the drive shaft 2 is covered with a The positioning sleeve 4, the positioning sleeve 4 and t...

Embodiment 2

[0032] The transmission shaft 2 is divided into multiple sections, and each section is fixed by hinges so that it can be folded and stored conveniently. The other parts of the device are the same as in Embodiment 1.

[0033] The device using method of the present invention comprises the steps:

[0034] 1. Reset the reading first, so that the pointer 3 is aligned with the reference line on the positioning sleeve 4.

[0035] 2. The sleeve 6 is in reliable contact with the adjustment part.

[0036] 3. Hold the positioning sleeve 4 with the dial with one hand, and turn the operating handle 1 clockwise or counterclockwise with the other hand according to the adjustment needs.

[0037] 4. After a stage of adjustment is completed, read the adjustment amount on the dial of the positioning sleeve 4 and record it, repeat step 3 to adjust the pressure ratio regulator, and repeat until the adjustment is qualified.

Abstract

The invention provides a pressure ratio control unit precise adjustment tool and an application method thereof. The pressure ratio control unit precise adjustment tool comprises a transmission shaft.A sleeve is arranged at the tail end of the transmission shaft. The inner diameter of the sleeve is the same as the outer diameter of a position to be adjusted. A positioning sleeve is arranged at theposition near to the front end of the sleeve. The positioning sleeve and the transmission shaft are in clearance fit. A baffle is arranged on the transmission shaft and is arranged on the end face ofthe side, facing the sleeve, of the positioning sleeve. A dial is arranged on the end face of the other side of the positioning sleeve. A pointer is arranged on the transmission shaft. The pointer makes contact with the dial. With the pressure ratio control unit precise adjustment tool and the application method thereof, in the application process of an engine, a pressure ratio control unit can be precisely adjusted, it is avoided that accessories need to be replaced because the adjustment amount is overproof, the adjustment time is shortened, and equipment loss is reduced.

Description

technical field [0001] The invention belongs to the field of aero-engines, and relates to a precise adjustment tool for a pressure ratio regulator and a using method thereof. Background technique [0002] When a certain type of engine pressure ratio regulator is used in the field, due to the influence of technology and climatic conditions, frequent failures occur. At present, there is no such precise adjustment tool in this field. The traditional adjustment method is affected by the operating space. Relying on general-purpose tools, there are safety hazards in the adjustment process. It is difficult to operate based on visual estimation of the adjustment amount, and it is impossible to accurately control and record the adjustment amount. The test run takes a long time, and the fuel consumption and equipment loss are relatively large. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the above-mentioned prior art, a...
