Abstract
The invention relates to an amphibious hard-alloy mining vertical pump capable of running in idling or being in series-connection. U-shaped protective walls are arranged at two ends of an insulating connector of a submersible motor and disposed outside a metal conductor, extend out of an insulating body of the insulating connector and are provided with conductor wire opening. The insulating connector can be a single-phase connector used for each phase of conductor wires individually, or a three-phase integrated connector, and each end of the three-phase integrated connector is provided with three U-shaped protective walls. Opening directions of all the U-shaped protective walls are the same. The size of the connector is smaller than that of the conventional product, accumulation of dew is avoided, and advantages can be remarkable specially when large-section conductor wires are connected with the connector.
Description
Technical field
The present invention relates to a kind of cemented carbide idle running amphibious husky pump of can connecting, it is land and dual-purpose amphibious type water pump under water, is applicable to carry the sand-discharging submerged pump that contains solid abrasive particles in the liquid or land with vertical pump.
Background technique
Prior art, " vertical pump for mine " by name has three patent of invention: ZL200410078876.4, ZL200410078879.8, ZL200410078880.0.
At present, not yet retrieve can connect cable coupling box and the wiring base of amphibious husky pump and submersible machine thereof of cemented carbide idle running and have the not ponding technological scheme convenient with being connected heavy gauge wire of insulation retaining wall.Along with husky pump maximizes, power of motor increases, and conductor cross-section increases, and it is little to be badly in need of volume, does not gather dew, and large-section lead connects very easily wiring base and terminal box, but such difficult problem fails to solve so far.
