換えを頻繁に行うことになり、作業効高が低下する。(Prior art and its problems) In Bonn f, in which the main impeller in the pump casing is connected to the drive shaft and the drive shaft bearing is supported on the guide vane on the upstream side of the main impeller, the pump fluid is used to lubricate the bearing. Or it may be used as a coolant. In this case, conventionally, a passage is bored in the drive shaft, one end of which is disposed as a water inlet on the downstream side of the main impeller, and the other end is opened in the bearing part. In this case, since a passage can be bored in the drive shaft,
The strength of the drive shaft is reduced, and therefore the diameter of the drive shaft must be increased, resulting in an increase in the size of the drive shaft. Further, in order to prevent foreign matter in the fluid from being supplied to the bearing, a filter is disposed in the flow path, but this filter is susceptible to damage due to the stress caused by the rotation of the drive shaft. This results in frequent replacement of the filter, which reduces work efficiency.

According to the present invention, since the filter is housed in the casing, which is a stationary member, the filter is not subjected to centrifugal force and has a long life.

して機能する。(Example) The inducer 1 is fixed to one end side of the drive shaft 4, and then
The guide vane 2 is supported on the drive shaft 4 via a bearing 6. Furthermore, the main impeller 3 is fixed to the drive shaft 4. As is clear from the attached drawings, the drive shaft 4 holding the inducer 1, guide vanes 2, and main impeller 3 is attached to the pump casing so that the inducer 1 is on the upstream side and the main impeller 3 is on the lower i side. It can be kept within 5. Note that the guide vane 2 functions as a stationary side member.

に直交させ得るので、流路9の加工は容易である。A flow path 8 is provided in the pump casing 5. The flow path 8 opens at a portion where the main impeller 30 is located on the high pressure side. On the other hand, the guide vane 2 serving as a stationary member is provided with a passage 9 that communicates with the bearing 6, so that the passages 8 and 9 are communicated with each other. A filter 7 is arranged in the flow path 8. When a helical-shaped blade is used as the guide vane 2, the center line of the flow path 9 can be made orthogonal to the axis of the drive shaft 4, so that processing of the flow path 9 is easy.
主羽根車3により高圧となった流体の一部は、フィルタ
