4. Structure Characteristic of WQ Series Sewage Submersible Pump
WQ series submersible sewage pump is equipped with status indicator and protection device to ensure for pump safe and reliable operating.
1). The unique cable airproof is adopted, avoid leakage of cable.
2). Heat protector in stator assure of operating life of the motor.
3). The pump adopts outer recycling cooling design with motor power more than 18.5kw, which can keep the pump operating safely under the lowest water level.
4). A floating switch is installed at the bottom of motor chamber to protect the mechanical seal in the motor side.
5). The oil-water probe is installed at the up end of the oil chamber between pump and motor that can protect the mechanical seal in the side. If leakage occurs, the system will signalize and start protection.
6). Adopt perfect mechanical seal, the sealing material adopt tungsten carbide, silicon carbide and hard metal alloy, which can prevent the water from entering into the motor, and keep the operating reliable and safety.
7). The auxiliary impeller can balance the pressure outside of the mechanical seal, prevent the water entering into the oil chamber and prolong the life of the motor.
8). Unique impeller design, wide passage allow large solid and long fiber passing through freely, it features non-clog, convolve-proof and good passing ability.
9). The changeable wearing ring is installed between the impeller and the volute to keep the optimum operation conditions.
