This series of engineering Marine special diving motor is resistant to salt water diving three-phase asynchronous motor, used in the dredging of dredging ship supporting the reamer motors and mud pump motor, allow diving depth is not more than 30 m. The closed structure, shell for corrosion resistant steel welding and become, all fasteners for stainless steel material. Stator coil, slot insulation, varnish and other major insulation materials are chosen for heat resistance class F or class H materials, after many leaching and spray paint forming surface resistance, salt fog resistance wet paint, ensure motor reliable operation.
Supporting reamer diving motor generally USES 4, 6 very frequency conversion motor, type YSXP, allow constant torque control and speed regulation, to prevent axis current for bearing damage, out to the shaft bearing the adopt the special insulation structure, eliminate the axis of the current generation, ensure the service life of the bearings. The frequency conversion motor without encoder.
Mud pump motor supporting diving usually adopts the low speed and filling model motor oil, such as 16 extremely, type YSX, allow the pump impeller installed directly to the motor shaft stretch, the shaft bearing structure stretch the consideration for the radial and axial load to bear ability. Motor internal filling with special requirements lubricating oil, lubricate, heat conduction and pressure effect, installation requirements equipped with automatic pressure device.
Diving motor of static sealing the sealing rubber seal glue sealing and article, according to the different dynamic seals the installation and use of condition use of mechanical seal or oil seal, also can use both combination sealing form; Diving motor set seal junction boxes, access cables and connectors are used special seal measures to prevent the junction boxes happens inside seepage failure; The box can be used in a motor and cavity seal isolation, motor with winding and bearing inner cavity overheating protection sensor, motor and junction boxes with internal leakage alarm sensor, further protect motor in underwater safety operation.
The diving motor supporting the reamer or mud pump underwater, and adopts hydraulic motor allocate compared with installation is simple, high reliability, the efficiency of the system can be greatly increased 20% 30%, reduce fault point improving the running time, almost no oil leakage occurs, water environment protection, etc. And the seal box with common motor is also installation is simple compared, cooling condition is good, the equipment is small, do not need to match cabin pressure, no need for additional seal link, etc.
