。A method for preventing corrosion on the surface of a conventional seawater hydraulic machine will be explained with reference to FIG. In water turbine operation, the seawater flow P rotates the flow runner 2 in the direction of arrow Pl,
Although it generates power, the flow of seawater P has pressure, so the flow of arrow P3 becomes the flow of arrow p4. It flows in the direction of arrow P5, passes through the gap that normally exists between the main shaft 3 and the packing 14, and scatters in the direction of arrow P6. At that time, the scattered droplets collide with each surface of the bearing case bottom plate 5-1, the upper cover, and the surface of the main shaft 3, and cover each of these surfaces and the surrounding equipment surface with seawater components. Generally, each of these surfaces is coated, but due to the vibrations caused by the operation of hydraulic machinery and the deterioration of the paint over time, cracks occur in the coating, and seawater components It entered through the crack and damaged the aforementioned bearing case 4 and bottom plate 5-1. This has disadvantages such as accelerating corrosion on each surface of the upper cover 4, the main shaft 3, and the surfaces of surrounding equipment, impairing the safety of each part, and reducing the service life of the entire hydraulic machine. there were.
本発明の目的は、海水の飛散飛沫が機械表面に衝突しな

３内に淡水供給管１０より供給された圧力を保有する。In Figure 2, under the operating conditions of the water turbine, the flow of seawater P is indicated by the arrow P.
It flows in the direction of I to rotate the runner 2 and generate power.Also, under the conditions of pump operation, manual power is transmitted to the main shaft 3 (not shown), causing the runner 2 to rotate as described above for the water turbine operation. Rotating in the opposite direction, directing the flow of seawater in the direction of arrow P2, and pumping up, that is, pumping up water, under conditions that do not matter whether the turbine is operating or the pump is operating.
Since the seawater flow P or P2 has pressure, if there is a gap, it tries to pass through it. seawater flow P,
Or, if we explain by displaying a part of P2 on arrow P3, P
3 passes through the gap g2 formed between the upper cover 4 and the runner 2, reaches the runner back pressure chamber R2, and connects the packing 6 and the lower part of the main shaft 3 housed in the packing case 4-2 (4). The fresh water tries to flow into the fresh water chamber R3 through a gap g1 normally maintained between the fresh water and the outer diameter surface of the fresh water 3-1, with a flow path of P4+P. On the other hand, since the fresh water chamber R3 is filled with fresh water at a pressure slightly higher than the pressure held in the runner back pressure chamber R2 from the fresh water supply pipe 10 in advance, the seawater in the runner back pressure chamber R2 is It does not flow into R3. Also, fresh water room R
3 holds the pressure supplied from the fresh water supply pipe 10.

を防止することを可能とする。On the other hand, the flow of P3 flows out through the gap g normally maintained between the outer diameter of the stem 2]-1 of the stem 21 of the guide vane 21 and the inner diameter surface of the bearing case 4-3, and flows into the fresh water chamber R1. However, since the watertightness of the packing 20 in this part is very good, it is difficult for seawater 3) to flow into the freshwater chamber R1, but a small amount of seawater may flow into the freshwater chamber R1. If there is no fresh water in the area, seawater will stay there and cause damage to the upper blade bar J bottom plate 4-] and the bearing case 4-3. It corrodes the upper cover 4, etc. As a means for preventing this corrosion, fresh water is supplied to fill the fresh water chamber R1 from the fresh water supply pipe 1]. In addition, a salt concentration detector 8 is housed and installed in the fresh water room R8.
When salt above a predetermined value enters the freshwater room R+, this is detected, converted into an electrical signal, and sent to the freshwater supply control device via lead 4!8-1 (not shown). Electricity (No. 8 is delivered, and if the salt concentration in the fresh water room R3 exceeds a certain predetermined value, the flow rate control valve j8 installed in the drain pipe 12 and the flow rate control valve installed in the fresh water supply pipe 11 17 respectively, and fresh water is supplied from the fresh water supply pipe 11,
Water continues to be drained from the drain pipe 12 until the salinity in the fresh water chamber RI falls below a certain certain level, and when the salt concentration in the fresh water chamber I≧, becomes below a certain certain level, the flow rate control valve 18 is closed, and then,
The flow control valve 17 is closed on the condition that the freshwater chamber R1 is filled with freshwater, and the freshwater chamber RI is always filled with freshwater whose salinity is below a certain value. It is possible to prevent corrosion caused by seawater over the entire surface that comes into contact with freshwater.

整する。Another embodiment of the invention will be described with reference to FIG. The conditions for the water wheel rotation or pump operation of the seawater hydraulic machine are as explained above using the example in Fig. 2, but the flow of seawater with pressure passes through the gap g+ via the arrows P3+P4, and then passes through the gap g+ as shown by the arrow P5. However, there is a fresh water supply pipe 10. in the fresh water room RI. Fresh water is supplied through the flow control valve 16, and the pressure in the fresh water chamber R1 is set to be slightly higher than the pressure held in the runner back pressure chamber R2. The seawater does not flow into the freshwater chamber R3. In addition, the fresh water in the fresh water room R3 is
4 and the outer diameter of the main shaft 3 to reach the drain chamber R3, pass through the drain pipe 13, and be discharged to the outside of the device. Therefore, the phenomenon of splashing seawater splashing onto the bottom plate 5-1 of the metal case 5°, which increases corrosion, does not occur.
In addition, a salt concentration detector 9 is housed and installed in the freshwater room R.
When salt above a predetermined value enters the fresh water chamber R1, this is detected, converted into an electrical signal, and sent to the fresh water supply control device via the radar wire 8-1, and the salinity is detected. The opening degree of the flow rate control valves 16 and 17 is adjusted according to the concentration of fresh water to increase the amount of fresh water supplied.
The salt concentration in I is always adjusted to be below a predetermined value.
このように、淡水室Ｒ７内の淡水に接する面全体にわた
