2.Working principle of Submersible Sludge Pump

1. Design and Components of  Submersible Sludge Pump

Submersible sludge pump, as a special pumping equipment for sludge treatment, is widely used in industrial fields and wastewater treatment processes. The sludge handled by this type of pumping equipment is a mixture of semi-solid particulate matter and water. The design and component configuration of a submersible sludge pump have a crucial impact on its efficiency and practicality.

1. Motor and power supply:

Such pumps are often equipped with submersible motors designed for underwater operation. To ensure safe operation of the motor, special seals must be used to prevent water from entering. The power supply of the submersible sludge pump produced by OCEAN Pump has been carefully matched and can be customized according to the voltage and frequency of the customer’s location, such as 220V/380V/400V/660V, etc. The frequency can also be consistent with local standards, such as 50HZ/60HZ, etc. The motors and cables are specially designed and customized to adapt to various hydraulic environments.

2. Pump casing

The pump casing is designed to be robust, wear-resistant and corrosion-resistant to accommodate the abrasive particles and corrosive elements present in the sludge. Usually, the pump casing is made of cast iron, stainless steel or other corrosion-resistant alloys. The structural dimensions of the submersible sludge pump produced by OCEAN Pump are reasonably designed based on the principles of hydraulic engineering to ensure that the customer’s transmission medium is fully understood before providing selection suggestions to the customer, so as to recommend a suitable pump casing to the customer. Material.

3. Impeller:

As the core component of pumping, the design of the impeller is crucial. The layout of the blades or blades can effectively promote the flow of sludge. Usually, the impeller is made of wear-resistant materials to cope with use under different working conditions. In order to meet a wider range of needs, the OCEAN Pump design team developed a large flow channel impeller with a maximum particle diameter of up to 60mm without affecting the flow, lift and efficiency of the pump.

4. Sealing mechanism:

The article mentioned that in order to prevent water from entering the motor or other sensitive parts, seals are used for protection. Mechanical seals or lip seals are often used to maintain waterproof enclosures. These sealing solutions are based on the extensive experience of the OCEAN Pump design team over many years. For high-power submersible sludge pumps, we will customize special mechanical seals, or even use two sets of mechanical seals to ensure the sealing performance of the entire equipment.

5. Bearings:

High-quality bearings play a vital role in supporting rotating parts, ensuring stable operation and extending service life of the pump. The main goal of bearing design is to withstand heavy loads and wear conditions. OCEAN Pump Company’s bearing products widely use Harbin bearings, which have excellent quality, can withstand heavier loads, have excellent wear resistance and have long service life.

6. Sensors and controls:

At this stage, the variable frequency control cabinet has been the first choice equipment recommended by OCEAN Pump to customers, and its variable frequency start function can effectively protect the motor. In addition, we have equipped the pump with double cables, whose main function is to transmit signals to the motor. These include three transmission signal lines: leakage protection, overload protection and oil chamber water intrusion protection. Once water leakage in the oil chamber, motor overheating or current leakage is detected, the control system will immediately send a signal and shut down the machine immediately to ensure the safety of the surrounding environment and operators.

7. Inlet and outlet connections:

In recent years, OCEAN Pump has designed several improved devices for the inlet of traditional pumps, with the main goal of minimizing the risk of clogging while promoting efficient flow. The outlet part is equipped with a flow meter and pressure sensor, allowing customers to remotely control and monitor underwater sand pumping conditions in real time. By promptly adjusting the position and flow rate of the pump, clogging can be effectively prevented.
