Topic It offers the oirurihuta device which the sliding aspect in the oil interior shaft seal device of the submerged pump which can solve the problematical point which it occurs with the white conversion including the air bubble of the lube entirely the lubrication is done. SolutionsTo surround outside the double type shaft seal device 32 which is categorized to the top and bottom inside oil room 24 with annular tube body, 39 inside this annular tube body 39, the suction chamber 40 which has the inlet port 43 of bottom side, the emission room 41 which has the emission mouth 44 of top side, the aforementioned suction chamber consist three rooms which are made the acceleration room 42 where, is located between 40 of the intermediate section and the emission room 41 the aforementioned suction chamber 40 and the emission room 41 make larger diameter than the acceleration room 42, on the inside perimeter aspect of the aforementioned acceleration room 42 lube a in the emission room 41Groove 45 in order to lead according to revolving direction it is provided with arrangement of up-grade, inlet port width of 43 and emission mouth 44 equality to the width of the aforementioned groove 45 is set below that.
