Product Overview
WQ non clogging submersible sewage pump is a new generation of pump products successfully developed on the basis of introducing foreign advanced technology and combined with the use characteristics of domestic water pumps
It has the characteristics of significant energy-saving effect, anti continuous winding, non clogging, automatic installation and automatic control
It has a unique effect in discharging solid waste and long fiber waste

This series of pumps adopts unique impeller structure and new mechanical seal, which can effectively deliver solids and long fibers
Compared with the traditional impeller, the pump impeller adopts the form of single channel or double channel
It is similar to a pipe with the same section size, has very good overcurrent and is equipped with a reasonable volute chamber
The pump has high efficiency, and the impeller has passed the dynamic and static balance test, so that the pump has no vibration in operation

The hydraulic performance of the pump is advanced and mature
After testing, all performance indexes of the products meet the relevant standards
After the products are put on the market, they are welcomed and praised by the majority of users with their unique efficacy, reliable performance and stable quality t

Product features
1
The design of large flow channel anti blocking hydraulic components is adopted, which greatly improves the dirt passing capacity, and can effectively pass through fiber material 5 times the diameter of the pump and solid particles with a diameter of about 50% of the diameter of the pump

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

3
The pump shaft is chrome plated, which greatly improves the corrosion resistance and wear resistance of the shaft and significantly improves the service life of the whole pump

4
The connection between cable and motor adopts rubber sleeve overall vulcanization technology, which has long-term and reliable waterproof effect

5
The mechanical seal adopts double channel series seal, which is made of hard corrosion-resistant tungsten carbide
It has the characteristics of durability and wear resistance, which can make the pump operate safely and continuously for more than 8000 hours

6
The pump has the advantages of compact structure, small volume, convenient movement and installation, and there is no need to build a pump house
It can work by diving into the water, which greatly reduces the project cost

7
The oil-water probe is set in the pump oil chamber
When the mechanical seal on the water pump side is damaged, the water enters the oil chamber and the probe generates a signal to protect the pump

8
The full-automatic safety protection control cabinet can be equipped according to the needs of users to monitor the water wetting, power turning, overload and overtemperature of the pump, so as to ensure the reliable and safe operation of the pump

9
The double guide rail automatic installation system brings great convenience to the installation and maintenance of the pump
People do not have to go in and out of the sewage pit for this purpose

10
The float switch can automatically control the stop and start of the pump according to the required water level change without special personnel

11
Ensure that the motor is not overloaded within the service head range

12
According to the application occasion, the motor can adopt water jacket external circulation cooling system, which can ensure the safe operation of the electric pump under the condition of no water (thousand type)

13
There are two installation methods: fixed automatic stick installation and mobile free installation, which can meet different application occasions

Applicable occasions of the product
1
Discharge of industrial and commercial wastewater with serious pollution

2
Drainage system of urban sewage treatment plant

3
Sewage drainage station in residential area

4
Drainage station of civil air defense system

5
Sewage discharge from hospitals and hotels

6
Municipal engineering and construction site

7
Auxiliary machines for exploration and mining

8
Rural biogas digesters and farmland irrigation

9
Water supply device of waterworks

Pump service conditions
1
The medium temperature shall not exceed 60ic, and the gravity shall be 1
0 & middot; 1
3kg/dm3, pH value in the range of 5-9

2
For the pump without internal gravity circulation cooling system, the exposed liquid level of the motor shall not exceed 1 / 2
3
Generally, the pump must be used within the service head range to ensure that the motor is not overloaded
If it needs to be used within the full head range, it should be noted separately when ordering for the convenience of the manufacturer

4
During operation, the pump motor current shall not exceed the rated current of the motor
