What Are The Scope Of Use And Product Characteristics Of Submersible Pumps

Feb 05, 2025

Submersible pumps are suitable for conveying granular sewage and waste in industries such as chemical, petroleum, pharmaceutical, mining, paper industry, cement plants, steel mills, power plants, coal processing industry, as well as urban sewage treatment plant drainage systems, municipal engineering, construction sites, etc. Stainless steel submersible pumps can also be used to pump clean water and corrosive media.
What issues must be noted during the use and maintenance of deep well submersible pumps?
The submersible pump cannot operate without dehydration. Test run under anhydrous conditions for no more than 5 minutes. During the pumping process, if the water level does not drop significantly, it is important to ensure that the pump body is not exposed to the water surface for operation.
After the submersible pump is stopped, it cannot be restarted immediately. It must wait for the stored water in the pipe to flow back before starting. If water cannot be discharged after starting, the machine should be stopped immediately to investigate the cause and eliminate it.
Different models of submersible pumps should be used according to the specified head; The inner diameter of the matching rubber, iron or canvas pipes should meet the technical requirements.
When placing or lifting a submersible pump into or out of the water, it is necessary to hold the rope on the "ear side" and never pull the cable. If you want to move, disassemble or repair, you should first cut off the power supply.
The submersible sewage pump mainly has the following product features:
1. By adopting a unique single blade or double blade impeller structure, the ability of pollutants to pass through is greatly improved, which can effectively pass through fiber materials with a diameter of 5 times the pump diameter and solid particles with a diameter of about 50% of the pump diameter.
2. The mechanical seal adopts a new type of hard and corrosion-resistant tungsten carbide material, and the seal is improved to a double end face seal, allowing it to operate in the oil chamber for a long time, which can ensure the safe and continuous operation of the pump for more than 9000 hours.
3. According to user needs, a fully automatic safety protection control cabinet can be equipped to provide absolute protection against pump leakage, electric leakage, overload, and overheating, improving the safety and reliability of the product.
4. The float head can automatically control the start and stop of the pump according to the required liquid level changes, without the need for special supervision, making it extremely convenient to use.
5. 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.
6. The overall structure is compact, the volume is small, the noise is low, the energy-saving effect is significant, the maintenance is convenient, and there is no need to build a pump room. It can work underwater, greatly reducing the project cost.
7. The sealed oil chamber is equipped with high-precision anti-interference water leakage detection sensors, and thermal sensitive components are embedded in the stator winding to provide absolute protection for the water pump motor.
