Model QW -Sewage Submersible Pump
The QW and WQ non-blocking submersible sewage pump is a new generation of pump products developed on the basis of the introduction of foreign advanced technology and combined with the characteristics of domestic water pumps. It has remarkable energy saving effect, anti-winding, no clogging, automatic installation and Features such as automatic control. It is convenient in discharging solid particles and long-fiber waste, and has a unique effect. The pumps feature a unique impeller structure and a new mechanical seal that efficiently transports solids and long fibers. Compared with the conventional impeller, the impeller of the pump adopts a single flow path or a double flow path. It is similar to a curved pipe of the same cross-section.
It has very good over-flow and is equipped with a reasonable volute to make the pump effective. High and impeller dynamic and static balance test, so that the pump has no vibration during operation. The hydraulic performance of the pump is advanced and mature. The performance indicators of the products have reached the relevant standards. After the products are put on the market, their unique effects, reliable performance and stable quality are welcomed and praised by the users.
Second, QW, WQ submersible sewage pump application range
- Municipal engineering, construction sites;
- Sewage discharge from residential areas;
- Sewage discharge from hospitals, hotels, etc.;
- Urban sewage treatment plant drainage system;
- Civil air defense system drainage station, water supply device of the water plant;
- Discharge of heavily polluted sewage from factories and businesses.
- The design of large-flow anti-blocking hydraulic components greatly improves the ability of dirt to pass through, and can effectively pass 5 times of fiber material of the pump diameter and solid particles with a diameter of about 30% of the pump diameter.
- The design is reasonable, the matching motor is reasonable, the efficiency is high, and the energy saving effect is remarkable.
- The mechanical seal adopts double-channel series sealing. The material is hard and corrosion-resistant tungsten carbide. It has the characteristics of durability and wear resistance, which can make the pump run safely for more than 8000 hours.
- The pump is compact in structure, small in size, convenient to move, easy to install, no need to build a pump room, and can work in submerged water, greatly reducing the project cost.
- The oil pump is provided in the pump oil chamber. When the mechanical seal on the pump side is damaged, the water enters the oil chamber, and the probe generates a signal to protect the pump.
- According to the needs of users, the automatic safety protection control cabinet can be used to monitor the leakage, leakage, overload and over-temperature of the pump to ensure reliable and safe operation of the pump.
- Double-rail automatic coupling installation system brings great convenience to the installation and maintenance of the pump, and people do not have to enter and exit the sump for this purpose.
- The float switch can automatically control the pump to stop according to the required water level change, without the need for special care.
- Ensure that the motor is not overloaded during the use of the lift range.
- According to the use occasion, the motor can adopt the water jacket type external circulation cooling system to ensure the safe operation of the pump in the waterless (dry) state.
- The installation method has two types: fixed automatic coupling installation and mobile free installation, which can meet different use occasions.
