1.What is Submersible Dredging Pump
Submersible dredging pumps are specialized equipment for underwater dredging operations and are used to remove sediment, mud or debris from the bottom of water bodies such as rivers, lakes, ports and channels. This type of pump is designed to operate in underwater conditions, with its centrifugal pump immersed directly in water or mud. The motor and impeller have waterproof seals to effectively prevent water ingress and damage.
Dredging is a significant engineering activity aimed at creating and maintaining navigable waterways, deepening water depths, and facilitating land development. Submersible dredging pumps play a crucial role in this process by removing sediment from the water body’s floor, ensuring clear waterways. Their direct immersion in water enables efficient transportation of sediment, mud, and debris, contributing to the sustainable utilization of water resources.
OCEAN Pump, a leading manufacturer in the industry, designs submersible dredging pumps specifically for underwater applications. These pumps are extensively utilized in various scenarios, including rivers, lakes, ports, and channels. The waterproof and sealed motor and impeller guarantee the stability and reliability of the equipment during submersible operations. By effectively cleansing the water body’s floor, submersible dredging pumps help prevent water siltation, enhance navigation in waterways, and promote the sustainable utilization of water bodies.
2.Key Factors When Choosing a Submersible Dredging Pump
OCEAN Pump’s submersible dredging pump is primarily designed to handle a wide range of slurry compositions, encompassing both coarse and fine particles. These pumps excel at pumping slurries with high concentrations of solids, typically exceeding 50% by weight. To address potential challenges such as clogging and excessive wear, the R&D department at OCEAN Pump has developed large channels and replaceable wear-resistant impellers. The impellers are crafted from durable materials, such as high-chromium alloys, to withstand the abrasive nature of the slurry.
Submersible dredging pumps offer several advantages in various mining applications, including mineral extraction, ore processing, and tailings treatment. These advantages include high efficiency, wear resistance, energy savings, adaptability, and environmental friendliness. OCEAN Pump’s product lineup is carefully curated to cater to specific requirements, ensuring that you can find a suitable submersible dredging pump that addresses your needs effectively.
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.
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.
