Drain part and contain electrical cell in pit of this drain part

The utility model discloses a drain part, it is used for the well drilling with electrical cell in the pit, the drain part is set up as to change to get into the drive a plurality of water conservancy diversion passageways of turbine pivoted flow of fluid direction, in, the drain part include the body with set up in a plurality of water conservancy diversion baffles of body inner wall are adjacent form between the water conservancy diversion baffle the guide of water conservancy diversion passageway flow of fluid. The utility model discloses the excessive impact of drilling fluid to the blade has been reduced to the drilling fluid that can make great majority passes through water conservancy diversion collision on impeller blade the biggest acting position. 本实用新型公开了种导液部件，其用于钻井用井下发电单元，所述导液部件被设置为改变进入驱动所述涡轮转动的流体的流动方向的多个导流通道；中，所述导液部件包括本体和设置于所述本体内壁的多个导流挡板，相邻的所述导流挡板之间形成所述导流通道引导所述流体的流动。本实用新型减少了钻井液对叶片的过度冲击，并且可以使大多数的钻井液通过导流碰撞在叶轮叶片最大做功位置上。
