CHINA FACTORY SUBMERSIBLE SEWAGE PUMP TYPE WQ/S,WQS WITH KNIFE GRINDING SHREDDING TYPE. SEWAGE PUMP SERIES WQ/S,WQS CHINA SUPPLIER,FACTORY AND MANUFACTURER

      WQ/S type submersible sewage pump with knife chopper is a new type of sewage equipment designed and produced according to national standards on the basis of foreign advanced submersible sewage pump technology. This series of pumps has the advantages of simple structure, strong sewage discharge and high efficiency and energy saving. At the same time, it can be equipped with automatic control and automatic installation of auto-coupling devices, so that the combination of the pumps is better, and the operation of the pumps is safer and more reliable.

 

 

      The submersible sewage pump has many advantages, the outstanding one is that it can be used directly in the water. However, when there is no trash rack or it is inconvenient to install the trash rack, the common submersible sewage pump often has the phenomenon that the pump and the pipeline are blocked by the larger debris in the sewage, causing trouble to the user. In order to solve this headache, our company has developed a submersible sewage pump with knife chopping , which not only has all the advantages of the usual submersible sewage pump, but also has the following unique advantages:

1. The S-type double-blade impeller can shred sacks, plastic woven bags, canvas gloves, leather gloves, cotton woven gloves, as well as daily plastic bags, cloth, toilet paper, sanitary napkins, cotton threads and other objects and discharge them smoothly. It can completely avoid the pump and pipeline being blocked by the debris in the sewage, and it is not necessary to set up expensive sewage blocking and decontamination devices when using it.

2. The impeller and pump cover are made of rust-resistant materials and undergo heat treatment. The cutting edges on the impeller and pump cover have sufficient hardness and corrosion resistance, so they are extremely wear-resistant and can remain sharp for a long time.

3. The size of the impeller flow passage and the size of the pump body flow passage are precisely matched, so that the chopped debris can pass through smoothly.

4. The unique arrangement of bearings and mechanical seals makes the cantilever of the shaft very short, and the rigidity and strength of the shaft are high. In this way, the vibration of the shaft is very small, which greatly reduces the leakage of the mechanical seal; the shaft can withstand a large amount of stress. Shock load; the bearing is completely in the oil bath of the oil chamber, which can get good lubrication and cooling, and still has a long life even under the heavy load working condition where the pump shreds hard objects from time to time.

5. Both the pump side and the motor side are equipped with mechanical seals to achieve reliable double submersible shaft seal protection for the motor. The oil in the oil chamber fully lubricates and cools the mechanical seal. The mechanical seal area on the pump side has a structure for shredding and driving out debris, so that debris can not accumulate or deposit in the mechanical seal cavity, so as to avoid it affecting the normal operation of the mechanical seal.

6. The scraping grooves set between all the overcurrent rotating parts and the fixed parts can scrape off the thin and tough debris squeezed between the overcurrent rotating parts and the fixed parts, so as to avoid increasing the pump power or blocking the rotor. .

7. It can be equipped with double-rail automatic coupling installation system according to user needs, which brings great convenience to installation and maintenance, and people do not need to enter the sump for this purpose.

8. It can be equipped with a fully automatic safety protection control cabinet according to the needs of users, which can absolutely protect the pump from water leakage, electric leakage, overload and over-temperature, etc., which improves the safety and reliability of the product.

9. It can be equipped with a float switch according to the needs of the user, which can automatically control the start and stop of the pump according to the required liquid change, without the need for special personnel, and it is extremely convenient to use.  

      It is suitable for conveying liquids containing solid particles, long fibers, and special Dirty, sticky and slippery sewage can also be used to pump clean water and weak corrosive media.

1. The temperature of the medium does not exceed 60℃, the density of the medium is 1.0-1.3×103kg/m3, and the PH value is within the range of 5-9;

2. The motor part exposed to the water surface should not exceed 1/2;

3. The main parts of this model pump are made of cast iron, so it cannot be used for pumping highly corrosive liquids.

Note: If users have special requirements (such as high corrosive medium), they can put forward when ordering, in order to provide products with more reliable materials.
