Abstract
PURPOSE: To automatically feed priming water of the dredging pump and the lubricating water of the cutter by conneting the discharge side of the water pump to the discharge side of the dredging pump through a check valve while the discharge side of the pump connected to the water pipe on the bearing of the cutter.
CONSTITUTION: When the water pump 18 is actuated, water discharge from the pump 18 is fed to the dredging pump 10 and the water pipeline 26 by way of a choke valve 34 and a check valve 35, and the same time, the water is fed to the water pipes 23 and 24, where it first reaches the sand discharging pipe 17 because of extremely small clearances 19a and 20a. Upon the driving of the dredging pump following the opening of the cock 30, the check valve is closed to stop the supply to the sand discharging pipe 17 and the water from the water pump 18 is sent to the water pipes 23 and 24. Upon the halting of the dredging pump 10, the check valve 35 is opened to allow the priming water automatically to be sent the dredging pump 10 and the water pipeline 26 from the water pump 18.
