Seven Elements Of Submersible Dredge Pump Design
Submersible dredge pump, is also known as submersible sand pump, submersible slurry pump, submersible heavy duty pump, is a new pump type designed and developed which are highly used for dredging, reclamation, seabed, sand dredging and piping. The pump is composed of two parts: motor and pump along with the mechanical seal assembly. The motor and the pump are combined with the same shaft (rotor). The entire pump has a short length and a compact structure. Equipped with a variety of protection devices, dredge pump operates safely and reliably.
Submersible Dredge Pump Design
The submersible dredge pump is designed for dredging solid (sand, gravel, rock etc) underwater and piping to another distination. When the dredge pump is required to operate, the pump and the motor are below the liquid level. The submersible dredge pump does not need to consider the cavitation problem, with the reason that, dredge pump impeller and casing are immersed in the water/slurry.
Three Elements Of Submersible Dredge Pump Design
1.The submersible dredge pump overview
Beside of the main dredge pump impeller, there is a stirring impeller at the bottom to spray the precipitated slag into a mixed liquid of water and solid particles. The pump can achieve high concentration delivery without auxiliary equipment. The unique sealing device can effectively balance the pressure inside and outside the oil, balance the pressure at both ends of the mechanical seal, ensure the reliable operation of the mechanical seal to the maximum extent, greatly extend the service life, and the motor can increase the water inlet detection according to user requirements. Various protection devices such as overheating enable the product to operate safely for a long time under severe working conditions.
2.The structure characteristics and working principle of the submersible dredge pump
The submersible dredge pump is a coaxial pump and motor. When the dredge pump is in working, the shaft rotates the pump impeller to transfer energy to the slurry medium in order to generate a certain flow rate, which drives the solid material to flow and realize the slurry transportation.
The selection design of the submersible dredge pump has a great influence on the service life and operational stability of the dredge pump. A scientific and rational selection design will affect whether dredge pump can achieve the best efficient operation.
3. The characteristics of the efficient operation of the dredge pump:
(1). High quality disposable lubrication bearings.
(2). Seal monitoring Inject oil into the oil chamber between the motor and the pump cover. As a protection zone, the sensor is sealed and monitored. Once it leaks, it will shut down immediately.
(3). The hydraulic components of the large channel are designed to ensure that particles of a certain size are not blocked and reduce failure.
(4). The motor shaft is made of stainless steel, and the rotor is tested for dynamic balance, which is more perfect.
(5). Double mechanical seal, made of silicon silicate/titanium hydride (or tungsten titanate/titanium tungsten) to ensure long-term reliable operation of the pump.
