Working conditions

Model meaning
Structure Description

★Bearing:
Imported SKF, NTN bearings, reasonable configuration, can extend the service life of the pump.

★Cooling:
Built-in cooling system, whether the motor is above or below the liquid level, can ensure the normal operation of the pump. A portion of the liquid is extracted to draw the vibration generated by the motor from the pump cycle to the cooling cylinder and pump housing. When external cooling is required, the cooling jacket can be separated from the pump housing and connected to the cooling system separately.

★Motor:
Class F insulation, maximum working temperature 155 ℃, protection grade IPX8, good sealing effect.

★Mechanical seal:
The German Bogman mechanical seal is adopted, and the two-way seals are connected in series and work separately to isolate the motor from the pump seal and provide double protection for the motor.
The pump side sealing material is tungsten carbide/tungsten carbide, and the motor side sealing material is graphite/silicon carbide.

★Oil room:
The oil lubricates and cools the mechanical seal and prevents liquid from penetrating into the motor for additional safety. A certain amount of air is left in the oil chamber to reduce the accumulated elevated pressure.

★Impeller:
After optimized design, the impeller will not be blocked when conveying liquid, has the best flow and speed, and has the highest efficiency. Each working condition has a suitable impeller to choose from.
According to the extracted medium, there are single-leaf, double-leaf and three-leaf impellers to choose from.

★Pump casing:
Using CAD/CAM technology, the highest efficiency and minimum wear.

★Monitoring system:
Three series thermal control switches are embedded in the stator, which are in a "normally open" state at normal temperature and open when the stator temperature reaches 125°C.
The oil chamber is equipped with a water leakage probe to detect water leakage. When the mechanical seal on the pump side leaks and the oil-water ratio in the oil chamber reaches a certain concentration, an alarm signal (indicator light) will be issued to automatically cut off the power supply and stop the pump.

The maintenance personnel should replace the lubricating oil in time, check the mechanical seal on the pump side, and replace it if necessary.

Motor junction boxes of 30kW and above are equipped with water leakage probes to check whether the cable seal is leaking.,

★float switch:
When the mechanical seal on the motor side leaks, the liquid enters the switch chamber and reaches a certain height, and the float switch will issue a warning signal (the indicator light is on).

Application case of submersible sewage pump in Algerian sewage treatment plant

Introduction

Globally, sewage treatment is an increasingly important topic, especially in the context of rapid urbanization and industrialization. As an important country in North Africa, Algeria's urban and industrial development has a growing demand for sewage treatment. With its advanced submersible sewage pump technology, Shanglishi Pump Group has successfully applied it in multiple sewage treatment plants in Algeria, demonstrating the superiority of its products. This article will elaborate on the nine characteristics of Shanglishi Pump Group's submersible sewage pump through specific data comparisons, and analyze it in combination with actual application cases in Algeria.

Background of sewage treatment in Algeria

Algeria is a country with rich natural resources and vast land, but with the acceleration of urbanization, sewage treatment problems are becoming increasingly prominent. According to data from the Algerian National Water Company (ADE), in 2022, Algeria's urban sewage treatment rate was only 60%, and in some areas, this proportion was even less than 50%. In order to improve this situation, the Algerian government has increased its investment in sewage treatment facilities in the past few years, especially in large cities and industrial areas.

Features of Shanglishi Pump Group's submersible sewage pump

1. Strong sewage discharge capacity

Shanglishi Pump Group's submersible sewage pump is designed to handle liquids containing solid particles and can effectively discharge sewage, wastewater, etc. In the application of a sewage treatment plant in Algeria, the sewage pump has a sewage discharge capacity of 500 cubic meters per hour and can easily handle sewage containing solid particles with a maximum diameter of 50 mm. This performance greatly improves the efficiency of sewage treatment and reduces the treatment time.

2. Efficient motor

The submersible sewage pump is equipped with a high-efficiency motor to ensure stable power output under various working conditions. In actual use in Algeria, the motor efficiency of the submersible sewage pump reaches more than 90%, which significantly reduces energy consumption. Compared with traditional pumps, the use of Shanglishi Pump's submersible sewage pump can save about 30% of electricity costs.

3. Wear-resistant materials

The pump body and impeller are made of wear-resistant materials to extend service life and reduce maintenance costs. In the sewage treatment plant in Algeria, after one year of use, the wear rate of the submersible sewage pump was only 2%, while the wear rate of the same industry products was as high as 10%. This difference effectively reduces the frequency and cost of maintenance.

4. Automatic coupling device

Many submersible sewage pumps are designed with automatic coupling devices for easy installation and maintenance. In the application case in Algeria, the installation time was shortened by 50%. The operator only needs to put the pump into the sewage tank, and the automatic coupling device can quickly complete the connection, greatly improving work efficiency.

5. Anti-clogging design

The anti-clogging design of the impeller and flow channel can reduce the risk of clogging and ensure the smooth operation of the pump. In the sewage treatment plant in Algeria, after using the submersible sewage pump of Shanglishi Brand, the number of clogging incidents was reduced by 80%. This not only reduces downtime, but also improves overall processing capacity.

6. Multiple control methods

Submersible sewage pumps can be equipped with multiple control methods, such as float switches, liquid level controllers, etc., to adapt to different working environments. In the sewage treatment plant in Algeria, a liquid level controller is used to monitor water level changes in real time, ensure the automatic start and stop of the pump, and improve the intelligent level of operation.

7. High protection level

Shanglishi Brand submersible sewage pumps usually have a high IP protection level to ensure safe operation in humid and watery environments. In the sewage treatment plant in Algeria, the IP68 protection level of the submersible sewage pump effectively prevents the intrusion of water and dirt, ensuring the long-term stable operation of the equipment.

8. Compact structure

The submersible sewage pump has a compact design and occupies a small space, which is easy to install in a limited space. In the sewage treatment plant in Algeria, the compact design of the submersible sewage pump enables it to be installed smoothly in a small space, optimizing the space utilization of the plant.

9. Low noise operation

The optimized design makes the submersible sewage pump low noise during operation, suitable for noise-sensitive environments. In the sewage treatment plant in Algeria, the noise level of the submersible sewage pump is controlled below 60 decibels, ensuring the quietness of the surrounding environment and meeting local environmental protection requirements.

Data comparison analysis

By comparing the actual application data of the submersible sewage pump of Shanglishi Pump Group with that of other brands of submersible sewage pumps in the sewage treatment plant in Algeria, its advantages are further highlighted.

Features	Shanglishi Brand Submersible Sewage Pump	Original Submersible Sewage Pump
Drainage capacity（m³/h）	500	350
Motor efficiency	90%	70%
Wear rate	2%	10%
Installation time (hours)	2	4
