TKBS 在疏浚作业中累积运行时间。 Cutter heads grinding through clay and rock, submerged pumps moving sand and gravel slurry, trailing arms working ten metres below a vessel under way，every duty cycle that punishes a motor, the dredge industry runs continuously.
绞吸式挖泥船使用旋转切割头破碎海床, 然后通过潜水泥泵泵送泥浆。两个电机位置: 位于梯架末端的切割驱动,以及潜水泥泵。
同一平台也用于深海采砂及采矿工况，如泥浆输送和矿井排水。材料与密封根据土质选配：TKBS 电机适应几乎所有化学土质成分。
两者都处于电机所能承受的最具磨蚀性的环境中。 切割电机在齿牙击中岩石时承受冲击负荷。 The submerged pump motor runs continuously against a heavy slurry head.
TSHD 沿海床拖曳一根或两根吸管, drawing slurry up into the vessel's hopper. 潜水泥泵位于水下, halfway down the suction pipe，the only practical place to keep prime at depth.
电机就装在这台潜水泵上。 Trident builds it pressure-compensated, oil-filled where the duty demands it, and matched to the pump's inverter drive for the variable speed control TSHD operations need.
深海采砂 is the most demanding submersible duty Trident motors see. The vessel sits in open water above a mining grid; the pump unit operates at depths where ambient pressure compresses chamber gas and stresses every seal.
一型I TKBS motors are built specifically for this duty. Automatic pressure balancing devices keep internal chamber pressure equalised with the surrounding water column. 多级轴密封 and oil-filled chambers handle the ambient hydrostatic load.
每个疏浚工况都结合了四种严苛的条件。 A motor built for industrial pumping will not survive，the engineering choices have to be made for this specific environment, from the winding insulation up.
沙石泥浆以高速通过泵叶轮。密封面、轴套和轴承迷宫承受连续的颗粒侵入压力。
切割头撞击黏土、岩石和障碍物。每次冲击都是通过联轴器传递到电机轴和定子的扭矩尖峰。
疏浚电机每天运行 18 至 24 小时,持续数周。散热必须在没有空气冷却的情况下工作，电机必须将损耗散入海水。
在两次部署之间电机会浸没数月。在电机停转时密封件必须承受压差，此时密封面不会通过旋转得到刷新。
TKBS 结构中的每个工程决策 maps directly to a dredging duty condition. 电机内没有任何东西是因为它在数据表上好看而存在的。
机械密封主级,油封次级,氟橡胶静密封圈。套筒材料按泥浆硬度精选。
鼠笼式转子按冲击扭矩设计。切割驱动端的轴径和键按重复冲击负荷设计。
高温绕组绝缘。通过焊接外壳将热量传导至周围海水,按 S1 连续工况设计。
通过灌封密封电缆连接,以防止长时间静态期间水通过电缆芯的毛细管进入。
Automatic pressure balancing device on 一型I motors. Internal chamber pressure tracks ambient to 300 米 without overloading static seals.
Whether it is a replacement for an obsolete motor, a new build specification, or an upgrade to add VFD compatibility，Trident engineers respond with a TKBS 配置 matched to the duty.
