Overhauling date: 2001.01.06.
Purpose: For continuous survey
At the time of on duty checking, we sounded noise from FO. Purifier NO.1 bearing chamber, so we decided to overhauled it. Just then, we thought of overhauling work could be together to do with annual survey.
Procedure:
(1.) Disconnected water feed line and dismounted handle connection piece. Then, unscrew fastening bolts.
(2.) Unscrew small lock ring with hook wrench (left-hand thread), and removed centripetal pump and spacer ring.
(3.) Using pressure tools, then, unscrewed lock ring and removed it.
(4.) Lift off bowl top, removed separating disk.
(5.) Unscrew the hex head screw from the spindle and removed it.
(6.) Using the assembling device, lift out the sliding piston.
(7.) Lift the bowl bottom out of the frame.
(8.) Pull out operating –feeding device together with the hose and put it aside, and removed spindle cap.
(9.) Unscrew Allen screws from neck bearing protection cap and removed it out of frame.
(10.) Unscrew the motor fastening bolts and given a slight movement, then, taken off the driving belt.
(11.) Pull spindle with fitted ball bearing out of the frame.
(12.) Checked every part and cleaned it. Renewed worn parts and hardened O-rings.
(13.) After the examination, assembled it in reverse process.
(14.) Renewed bearing chamber oil.
