·A prematurely failed vertical turbine pump shaft was investigated for root cause analysis The analysis involves operating conditions visual examination chemical composition bulk hardness microstructure and fractured surface analysis Visual examination clearly showed that the shaft had failed at the step region; however no evidence of fatigue striations/beach
·Due to the high in situ stress of the deep rock mass and the restraining effect of the surrounding rock the deep hole blasting of vertical shaft faces the problems of low borehole utilization rate and poor blasting effect In this regard this paper proposes a deep hole multi stage cut blasting technology of vertical shaft Preliminary engineering practice shows that such cut
correct wiring and rotation of motor shaft V a For vertical hollow shaft motor driven pumps ensure the top shaft nut adjusting nut and gib key are removed and the motor is not coupled to the pump The pump shaft can turn freely from the pump motor As an added pre caution on a one 1 head shaft assembly it is advisable
4 ·The rotor speed of the GS series vertical shaft crusher at the highest is clocked at 82m/s due to highly efficient cooling Compared with VSI series crushers GS series vertical shaft crushers have more capacity and lower power consumption The basic principle of operating a VSI crusher is to accelerate stones to break against each other in
Vertical Shaft Impactor VSI is a type of crusher that is used to reduce the size of rocks and other materials to create aggregates and other construction materials Rock on steel VSI on the other hand uses steel anvils to break down the material The design is ideal for medium to high abrasion materials with high reduction ration Among
·vertical shaft refers to a long cylindrical underground opening that runs vertically as water conveyance system in Hydropower projects Construction of a vertical shaft is not an break through point was achieved The excavation period of VS1 using Raise Climber was ended on 7/3/2079 after the breakthrough of shaft excavation The Raise
·Firstly the developed excavation machine is not sufficiently powerful to break large stones into ones with diameters of less than m in order to use the vacuum system efficiently Secondly this method was developed to construct a vertical shaft in a rock mass with sufficient strength so that earth retaining walls cannot be put in place
