摘要： The present invention relates to a fluid agitator which may stir fluid in a closed space without leakage of the fluid. The fluid agitator has a motive means and a bearing means installed in the closed space.In the fluid agitator employing a electric motor as the motive means, only the stator coil of the motor which is weak in its resistance against high temperatures and humid atmosphere is sealed in a sealing chamber. The sealing chamber may be provided with a cooling device to cool the inside thereof. The driving shaft of the motor is supported by a bearing having resistance to high temperatures and high humidity and is provided with an agitating blade.In the fluid agitator employing a turbine system as the motive means, a turbine chamber and a turbine blade are set in the closed space. A fluid supply is furnished to introduce fluid into the turbine chamber from outside of the closed space for driving and rotating the turbine blade. The turbine blade is connected to an agitating blade through a rotation transmission.

摘要： A mechanical seal for sealing a slurry liquid between a casing and a rotary shaft comprises a fixed seat ring; a rotatable slide ring in the casing and abutting against the seat ring to form a sealing face therebetween; a helical spring in the casing and surrounding the rotary shaft, and biassing the rotatable slide ring toward the seat ring; and a rotatable ring on the rotary shaft and rotatable with the rotary shaft and holding the spring at a predetermined position relative to the rotary shaft, the spring being interposed between the rotatable slide ring and the rotatable ring. A small space is provided between the casing and the rotatable ring and the rotatable ring has a helical projection on the outer surface thereof. The helical projection of the rotatable ring and the helical spring are directed such that upon rotation thereof a force is produced in a direction away from the sealing face and toward the interior of the casing. The spring is preferably a helical screw-thread-like member of rectangular cross-section.
