Type circle, axle stretch end are equipped with mechanically-sealing apparatus, can prevent outside moisture and moisture from entering motor cavity and preventing in machine absolutely
Edge lubricating oil leaks.Some filling type motor lower portions have pressurizer, its inner cavity oil can be remained in motor operation course
Pressure is greater than external water pressure.
C, Water-filled Type Submersible Motors
Water-filled Type Submersible Motors inner cavity is full of clear water (generally pure soft water), and axle stretch end is equipped with mechanically-sealing apparatus and rubber
Glue oil sealing can prevent external sewage or sediment contamination from entering motor cavity.Lower part is equipped with rubber bag tank, in motor operation course certainly
Hydraulic pressure inside and outside dynamic balancing machine prevents water inside and outside machine to be interchangeable by oil-sealing arrangement, enters electricity with water to reduce foreign matter
The chance of machine inner cavity.
Performance characteristics:
(1) due to much smaller than common 380V current of electric of the operating current of high-power submersible motor, to make
The volume of high-voltage motor greatly reduces, and has saved motor mounting space, reduces the cost of equipment.

Rate reduces combustion profit oil consumption cost of diesel engine etc..
(3) submersible motor control system is more simple and convenient than liquid oil motor system, and control speed is fast, and service efficiency is high, fortune
The row time is long, and maintenance management is simple.
(4) high-pressure immersed electromotor directly drives underwater dredge pump or reamer head by shaft coupling, saves and was driven in the past
Long axis, bearing block, gear-box and ancillary equipment reduce energy loss of motor during driving load, improve transmission
Efficiency.
(5) high-pressure immersed electromotor has the characteristics that structurally reasonable, easy for installation, reliable performance, is long-term work in underwater
The ideal driving equipment of environment.
