Title: Electrode of electrode type water level detecting unit for submerged pump
Inventor: OKUDA AKIRA
IPC: F04D15/00
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To facilitate a change in setting of the controlled water level corresponding to the real condition of a field of use, and to prevent the generation of damage due to the impact by fall and collision. SOLUTION: This electrode is formed by fitting a coil spring type extension electrode 3 to the inner peripheral surface or the outer peripheral surface of a tubular fixed electrode 2, which is led downward outside of a pump motor, from under the fixed electrode 2. The controlled water level is changed by cutting the extension electrode 3 at a desirable length, removing it, or exchanging it with one having a different length. With this structure, the fixed electrode having a relatively short length can be used, and since the fixed electrode has the tubular structure, the electrode having the excellent impact resistance in comparison with the conventional narrow and long rod-like fixed electrode can be obtained.
