1. Power options of Submersible Dredging Pump

1. Electric drive:

As a common driving method, electric drive is widely used in industrial and civil fields. Submersible dredging Pumps are usually driven by an electric motor, which is installed on the upper part of the pump. Through the connection between the motor rotor and the impeller, the rotational power of the motor is transmitted to the impeller. The advantage of the Submersible dredging Pump is that it can work normally in harsh environments, is easy to install and maintain, and can reduce the impact on the surrounding environment.
OCEAN Pump Company has rich experience and technical strength in the field of electric drive. They can provide electric Submersible dredging Pumps in various power ranges to meet different needs, including but not limited to 220V/380V/440V/600V, etc. In addition, the voltage frequency can also be customized to 50HZ or 60HZ according to country differences. Experiments have proven that all products can achieve corresponding power frequency values.
In addition, 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. To ensure safe operation of the pump, we also equip the pump with dual cables, mainly used to transmit motor signals. 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 to ensure the safety of the surrounding environment and operators.

2.Hydraulic drive:

Hydraulic drives are suitable for applications requiring high pressure and lift, especially when there is a lack of electrical power or when operating in hazardous environments. The advantage is that the motor will not be burned due to overload. When the pump runs overloaded, the oil will flow back to the tank through the overflow pipe without causing damage to other components. There are two applications for hydraulic drive: one is to directly use the excavator’s hydraulic pump station to drive, and the other is to establish an independent hydraulic pump station.
At present, the method of directly using the hydraulic pump station of the excavator to drive has gradually become popular. OCEAN Pump has expertise in hydraulic system design and manufacturing, providing high quality, reliable hydraulically driven Submersible dredging Pumps. Before purchasing a Submersible dredging Pump for a customer, we will fully understand the customer’s excavator model, power and displacement, and calculate and match the corresponding Submersible dredging Pump for the customer based on actual data.

2.Flow and Lift Head Requirements of Submersible Dredging Pump

When purchasing a Submersible dredging Pump, the selection of flow parameters is particularly critical. First of all, the required flow rate needs to be determined according to specific working conditions, taking into full consideration factors such as the type of liquid to be transported, the transportation distance, height, and pipeline resistance. It is recommended to reserve a certain amount of extra margin to accommodate possible changes in working conditions in the future. OCEAN Pump Technology Department provides complete technical information, including performance curves and dimensional drawings of the pump system. Before selecting a model for the customer, we will fully understand the customer’s flow, discharge height and discharge distance requirements, clarify the lift requirements, and ensure that the pump can provide sufficient lift to meet the delivery height requirements. Find out how your submersible pump performs at different flow rates by looking at its performance curves and make sure you match the system curves to achieve optimal pump efficiency.

When selecting a Submersible dredging Pump, in addition to flow rate, also need to consider the key parameter of head, because both determine the performance and scope of application of the pump. First, determine the required flow rate according to specific working conditions, fully considering factors such as liquid type, transportation distance, and pipeline resistance. At the same time, the lift requirements are clarified to ensure that the pump can provide sufficient lift to meet the delivery height requirements. The OCEAN Pump technical department will provide detailed technical support based on customer needs to ensure the accuracy of selection. Find out how your submersible pump performs at different flow rates and heads by looking at its performance curves, and make sure you match the system curves to achieve optimal pump efficiency. Considering possible changes in the future, choose a pump with variable frequency speed regulation function and adjust the flow rate and head according to actual needs to improve energy efficiency and reduce energy consumption. Taking these factors into consideration will help you choose a Submersible dredging Pump suitable for specific application scenarios to ensure its efficient and stable operation under various working conditions.

3.Submersible Dredging Pump Flow Solid Particle Size and Concentration

When purchasing a Submersible dredging Pump, the characteristics and concentration of flowing solid particles are crucial considerations. First, the size and type of solid particles in the slurry need to be identified to ensure that the pump is designed to handle them effectively. Generally speaking, the impeller of a Submersible dredging Pump adopts a closed design. Although it has a high lift, the flow rate is small and blockage is prone to occur. In order to solve this problem, the OCEAN Pump design team carried out targeted research and development and created a Submersible dredging Pump with a wide flow channel impeller that can pass large particles while ensuring flow and head. Choosing a pump with a larger solid particle passing capacity can effectively prevent clogging and improve pump operating efficiency.
In addition, OCEAN Pump has designed a variety of inlet joints for Submersible dredging Pumps for different working environments. For high-concentration slurry, a more powerful pump is required to achieve effective transportation and processing, and its overflow concentration can reach 60%. Taking the above factors into consideration, we ensure that the Submersible dredging Pump can handle various types of slurry stably and efficiently during practical application.

4 Wear Resistance of Submersible Dredging Pump

The wear resistance of a Submersible dredging Pump measures its ability to resist wear and tear on pump components caused by solid particles. When dealing with slurries containing particulate materials, the wear resistance of the pump is particularly critical. First of all, core components such as the impeller and pump casing of the pump should be made of wear-resistant materials. For example, the flow-passing parts of the Submersible dredging Pump produced by OCEAN Pump Company, including the pump casing, impeller, guard plate, water-absorbing plate, etc., are all made of high chromium Made of alloy Cr28 to resist the impact and wear of particles, it is called A05 in some areas. In order to ensure material quality, we use professional testing equipment to test factory products so that customers can purchase with confidence. Secondly, reasonable flow channel design and impeller shape can also reduce the impact and wear of solid particles on the internal components of the pump. All things considered, the wear resistance of a Submersible dredging Pump is a decisive factor in ensuring the long-term stable operation of the pump. Choosing a pump with excellent wear resistance is of great significance for handling slurry containing particulate materials.

5. Operating Environment of Submersible Dredging Pump

The operating environment of a Submersible dredging Pump has a direct impact on its performance and life. First, the working depth of the pump in the liquid needs to be considered to ensure that the appropriate diving depth is selected to meet the engineering needs. The Submersible dredging Pump produced by OCEAN Pump uses cables made of special materials and is suitable for operating environments with a diving depth of up to 200 meters. For such deep operating conditions, OCEAN Pump developed a special customized submersible motor and uniquely designed a mechanical seal to effectively prevent water leakage.
In addition, the variable frequency control cabinet has become the first choice equipment recommended by OCEAN Pump to customers, and its variable frequency start function can effectively protect the motor. At the same time, to ensure the stable operation of the pump, we equip the submersible dredging pump with dual cables, whose main function is to transmit signals to the motor. It includes 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.

The selection of a Submersible dredging Pump requires comprehensive consideration of factors such as flow requirements, flow solid particles and concentration, wear resistance, design and structure, anti-clogging ability, energy efficiency and operating costs, maintenance and upkeep, as well as supplier reputation and after-sales service.
