Vertical pump and urea synthesis plant |
| abstract |
A vertical pump includes: a rotary shaft; multi-stage impellers; a casing accommodating the multi-stage impellers; a mechanical seal provided in a penetration part of the casing for the rotary shaft; a balance sleeve, the balance sleeve being positioned between a final stage impeller of the multi-stage impellers and the mechanical seal in the penetration part for the rotary shaft; an intermediate chamber provided between the rotary shaft and the casing and provided on an opposite side of the multi-stage impellers across the balance sleeve in an axial direction of the rotary shaft, the intermediate chamber communicating with an intermediate stage impeller among the multi-stage impellers; a low pressure chamber provided between the rotary shaft and the casing, the low pressure chamber communicating with a low pressure side compared to the intermediate chamber; and a partition wall part dividing the intermediate chamber and the low pressure chamber. |
