1. Our WQ-type general sewage pump adopts a large flow channel anti-clogging hydraulic parts design, which greatly improves the dirt passing ability, and can effectively pass the fibrous material 3 times the pump caliber and solid particles with a diameter of about 30% of the pump caliber.
2. Reasonable design, reasonable supporting motor, high efficiency, energy saving effect is remarkable.
3. The mechanical seal adopts a double-channel tandem seal, the material is hard corrosion-resistant tungsten carbide, which is durable and wear-resistant and can make the pump run continuously for more than 8000 hours.
4. Compact structure, small volume, easy to move, easy to install, no need to build a pump room, submerged in the water can work, greatly reducing the project cost.
5. The pump oil chamber is equipped with an oil and water probe, when the mechanical seal on the pump side is damaged, water enters the oil chamber, and the probe generates a signal to protect the pump. A fully automatic safety protection control cabinet can be equipped according to the user's needs to monitor the pump's water leakage, power leakage, overload over-temperature, etc., to ensure that the pump runs reliably and safely.
6. Double-rail auto-coupling installation system brings great convenience to the installation and maintenance of the pump, and people don't have to go in and out of the sump pit for this purpose. Float shape can automatically control the pump stopping and starting according to the required water level changes, without the need for personal supervision. The use of head range to ensure that the motor is not overloaded.
7. According to the use of occasions, the motor can adopt the water jacket type external circulation cooling system, which can ensure the safe operation of the electric pump in the state of no water (dry).
8. There are two kinds of installation modes: fixed automatic coupling installation and mobile free installation, which can meet different usage occasions.
9. The pump body and impeller are designed using CAD technology and are repeatedly modified concerning the hydraulic model to match the pump body and impeller so that the flow channel is wide and dirt can pass through the pipeline. The impeller is strictly balanced to minimize vibration and extend the life of the bearings and mechanical seals.
