Application

Submersible sewage pump WQ (QW) type, also known as (non-blocking submersible sewage pump) is based on the reference of domestic advanced technology,

A new generation of pump products developed in combination with the characteristics of domestic water pumps, the non-blocking submersible sewage pump has significant energy saving effect.

Anti-winding, no clogging, automatic installation and automatic control. It has a unique effect in discharging solid particles and long-fiber waste.

This series of sewage pumps uses a unique impeller structure and a new mechanical seal to efficiently transport media containing solids and long fibers. The impeller is compared to a conventional impeller

The pump impeller is in the form of a single flow channel or a double flow channel. It is similar to a curved pipe of the same cross section and has a very good overcurrent with a reasonable volute.

The pump has high efficiency and the impeller static and dynamic balance test, so that the pump has no vibration during operation. The pump's hydraulic performance is advanced and mature.

The performance indicators of the products have all 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.

Feature

1. It adopts the design of large-flow anti-blocking hydraulic components, which greatly improves the ability of dirt to pass, and can effectively pass 5 times of fiber material of the pump diameter and solid particles with a diameter of about 50% of the pump diameter.

2, the design is reasonable, the supporting motor is reasonable, the efficiency is high, and the energy saving effect is remarkable.

3. 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.

4, the pump is compact, small in size, easy to move, easy to install, no need to build a pump room, can work in submerged water, greatly reducing the project cost.

5. There is an oil-water probe 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.

6. It can be equipped with automatic safety protection control cabinet according to user needs to monitor the leakage, leakage, overload and over temperature of the pump to ensure reliable and safe operation of the pump.

7. Double-rail automatic coupling installation system brings great convenience to the installation and maintenance of the pump. People do not have to enter and exit the sump for this purpose.

8. The float switch can automatically control the pump to stop according to the required water level change, without special care.

9. Ensure that the motor is not overloaded during the use of the lift range.

10. According to the use occasion, the motor can adopt the water jacket type external circulation cooling system to ensure the safe operation of the electric pump in the dry (dry) state.

11. There are two kinds of installation methods: fixed automatic coupling installation and mobile free installation, which can meet different usage occasions.

Working Condition

1. The sewage pump series products are applicable when the rated voltage is 380V and the power frequency is 50Hz.

2. The medium temperature does not exceed 40 degrees Celsius, the medium density is ≤1150kg/m3, and the PH value is between 5-9;

3. The altitude does not exceed 1000 meters;

4. The annual viscosity of the transport medium does not exceed 1000CP;

5. The product must be completely submerged into the water during operation, but the depth of diving should not exceed 10m;

6. The material of the product is mainly cast iron, which can not be used in medium with strong corrosiveness or strong corrosiveness;
