Title: Method and device for predicting life of plant structure
Inventor: ANZAI HIDEYA
IPC: G01M99/00
Filed: 1994-08-29
Abstract: PURPOSE: To predict the life of a structure by installing a sensor part consisting of a same metal material near a plant structure under a corrosive environment and guiding hydrogen through the sensor part after being generated due to corrosion to the outside of the structure and then measuring the amount of transmission of hydrogen in unit time. CONSTITUTION: A plurality of sensor parts formed by the same metal material as that of a plant structure placed under a corrosive environment is provided in an actual environment near the structure for forming a clearance. Hydrogen which is generated due to corrosion is transmitted through each sensor part and is guided to the outside from the structure. The amount of transmitted hydrogen per unit time is measured for cases where there is clearance and there is no clearance at the sensor part and the hydrogen concentration in metal for the presence or absence of clearance is estimated based on the result. A crack tip hydrogen concentration is obtained from the result and the three-axis stress at the crack tip which is assumed in the structure.  The time change of crack length is obtained from the time integration of the sum of the crack progress speed of the same metal under the concentration and the crack progress speed due to corrosion solution and the time when the crack reaches a limit depth is obtained, thus predicting life.

Title: Bearing lubricating device for pump
Inventor: HARADA ICHIRO
IPC: F04D29/04
Filed: 1985-09-18
Abstract: PURPOSE:To achieve the prevention of blockage in a lubricating water line and the damage of bearings by supplying fresh water as bearing lubricating water for a given period of time by means of a fresh water supply pump so as to prevent the breeding of oceanic life in said line, in a vertical shaft pump which supplies sea water as bearing lubricating water. CONSTITUTION:Usually, a line B is used to supply sea water as bearing lubricating water. And a fresh water supply pump separately installed is started for a given period of time to supply fresh water to the lubricating water line. The changeover from sea to fresh water is automatically carried out by means of a check valve installed, by making the discharge pressure of the fresh water supply pump higher than the supply pressure of sea water lubricating water. The period of 24hr in which fresh water is caused to flow is sufficient, and it is so arranged that changeover valves 19 are operated by a timer 20. Thus, the breeding of oceanic life in the bearing lubricating line can be prevented, and accordingly the blockage of the line brought about thereby and the damage of bearings due to the falling off of the dead bodies of shellfishes and the like can be prevented.
