Abstract

PURPOSE:To improve working efficiency in exchanging a filter by opening one end of a passage passing through a casing and a guide vane at the downcourse side part of a main impeller, while the other end thereof at a bearing, and providing a filter in said passage. CONSTITUTION:The passage of a pump casing 5 is opened at a part where a main impeller is positioned, and a passage 9 passing through the part of a bearing 6 is provided at a guide vane 2 so that both passages are connected with each other. A filter 7 is arranged in the passage 8, and thereby the part of high pressure fluid is purified by the filter 7 so as to be supplied to the bearing 6. With this arrangement, the passages are provided in the casing, and thereby the working, in comparison with the case that the passages are provided on the driving shaft, is simplified so that it is possible to facilitate the exchange of the filter.

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.

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.
