Characteristics of cutting type sewage pump

Characteristics of cutting type sewage pumpParameters: flow rate of 10m3/h, head of 10m, power of 0.75KW, speed of 2900r/min. Compared to ordinary submersible sewage pumps, its cutting function can effectively cut debris contained in sewage.Ru MaBags, plastic woven bags, canvas gloves, leather gloves, cotton woven gloves, as well as daily plastic bags, fabrics, toilet paper, sanitary napkins, cotton thread and other objects can be smoothly discharged to avoid blockage of pumps and pipelines by debris in sewage. There is no need to set up expensive interception and decontamination devices during use.

Characteristics of cutting type sewage pumpMain purpose:

1. The discharge of severely polluted wastewater from factories and businesses.

2. Urban sewage treatment plant drainage system.

3. Sewage drainage stations in residential areas.

4. Civil air defense system drainage station.

5. Wastewater discharge from hospitals and hotels.

6. Municipal engineering and construction sites.

7. Exploration and mining supporting equipment.

8. Rural biogas digesters for farmland irrigation.

9. The water supply system of a water plant.

10. Various breeding farms, slaughterhouses, septic tanks, etc.

1. The medium temperature does not exceed 60 ℃, and the medium density is 1.0-1.3kg/dm3, The pH value is within the range of 5-9;

2. The exposed liquid level of the pump motor part without internal self circulation cooling system shall not exceed 1/2;

3. In general, the pump must be used within the range of head to ensure that the motor is not overloaded. If it needs to be used within the full head range, it should be specified separately when ordering for the manufacturer to manufacture.

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

To solve this headache inducing problem, our company has developed a belt withEfficient cutting type submersible sewage pumpThis type of pump not only has all the advantages of a typical submersible sewage pump, but also has the following * * properties:

1. The S-shaped double blade impeller can shred and smoothly discharge objects such as burlap bags, plastic woven bags, canvas gloves, leather gloves, cotton woven gloves, as well as daily plastic bags, fabrics, toilet paper, sanitary napkins, cotton threads, etc. It can prevent pumps and pipelines from being blocked by debris in sewage, and does not require expensive interception and decontamination devices during use.

2. The impeller and pump cover are made of corrosion-resistant materials and have undergone heat treatment. The cutting edges on the impeller and pump cover have sufficient hardness and corrosion resistance, making them extremely wear-resistant and able to maintain sharpness for a long time.

3. The impeller channel size matches the pump body channel size accurately, allowing the shredded debris to pass smoothly.

4. The arrangement of bearings and mechanical seals in * 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 small, and the leakage of the mechanical seal is greatly reduced; The shaft can withstand significant impact loads; The bearing is immersed in the oil bath of the oil chamber and can receive lubrication and cooling, even under heavy load working conditions where the pump occasionally shatters harder objects, it still has a long service life.

5. Both the pump side and the motor side are equipped with mechanical seals to achieve reliable dual submersible shaft seal protection for the motor. The oil in the oil chamber provides sufficient lubrication and cooling for the mechanical seal. The pump side mechanical seal area has a structure for shredding and driving away debris, which prevents debris from accumulating or depositing in the mechanical seal chamber, thereby avoiding its impact on the normal operation of the mechanical seal.

6. The scraping groove set between all the overcurrent rotating parts and fixed parts can scrape off the thin and tough debris squeezed between them, avoiding an increase in pump power or blockage.

7. A dual rail automatic coupling installation system can be equipped according to user needs, which brings great convenience to installation and maintenance, and people do not have to enter the sewage pit for this.

8. According to user needs, a fully automatic safety protection control cabinet can be equipped to protect the pump from water leakage, electric leakage, overload, and overheating, improving the safety and reliability of the product.

9. According to user needs, a float switch can be equipped to automatically control the start and stop of the pump based on the required liquid changes, without the need for dedicated personnel supervision, making it extremely convenient to use
