Described here in the article is the operating principle of pressing deep blind hole of forged hi-pressure cylinder casing involving the processing method of twice hole-pressing and mould-stripping by "explosion".

The paper analyses the causes of higher vibration of the front radial bearing of CO2 comperessor Hp cylinder and present the corresponding solutions,and then solved the problem .

This paper analyzes and deals with the problem of the trip of CO_2 compressor set caused by high axial vibration of HP cylinder,andproposes the the paecautions against the reoccurrtence of similar incidents.

During the performance test implemented after turbine alteration,it is found that the HP cylinder extraction steam tempreture is abnormally high.

Based on the characteristics of stress distribution in high-pressure cylinder,the formula of calculating the maximal equivalent stress(inside wall) is educed according to the fourth strength theory and the quantitative relationship between cylinder's inside pressure and diametrical ratio and the fatigue limit were founded.

Temperature and stress analysis for high pressure cylinder of supercritical 1000 MW steam turbine;

Analysis of blast fault at the tail of high pressure cylinder in 600 MW turbine and countermeasures

In view of the problems of combustion in the cylinder and flame out of high pressure cylinder, the combus- tion and the causes of problem is analyzed, and the improving measurements are put forward.

Aim at the problems existed in the super high pressure cylinder in some factory,the super high pressure cylinder is taken the improved design by using the optimal design principle of shrunk-on double-layers cylinder.

According to the problems existed in the super high pressure cylinder, an improved design is accomplished.

Based on the analysis and calculation of the diametrical ratio and strss to a super high pressure cylinder, it is found that the diametrical ratio doesn t conform to the optimal design principle and the stress isn t well-distributed.
