Abstract

PURPOSE: To prevent scuffing as well as keep the efficiency of bearing constant regardless of the presence or absence of overflow from pump by providing a pump liquid level-holding part at the upper part of a bearing bush and also a bearing- lubricating part at the lower part.
CONSTITUTION: A pump liquid level holding part 19 at the upper part of a bearing bush 14 is provided radially with upper and lower supply holes 20a and 20b, and also its inner circumference is provided with a linear groove 21 leading to both the supply holes 20a and 20b. Also, a circular groove 24 is provided at the upper part of a pocket 23a above a bearing-lubricating part 22 and also connected to a discharge groove 25. Thus regardless of the presence or absence of overflow, sodium can be discharged to a lower low-pressure chamber 9 on the back side of impeller, and the efficiency of bearing can be kept sufficiently all the time.
