Technology share of DOH Dredge pump Structural features and applications.
DOH type of dredge pump is also a part of dredge pump which are highly used for mining, mineral processing, dredging sand, sludge, chemical etc. DOH type of dredge pump is also replaceable to AH Warman pump.
The structure of the DOH dredge pump
DOH type dredge pump is a horizontal, double-shell, axial suction centrifugal dredge pump. The main components are: bearing assembly, stuffing box, pump body, sheath, pump cover, impeller, front guard plate, rear guard plate, bracket (refer to the schematic diagram of the fractional dredge pump);
The discharge direction of DOH dredge pump can be rotated in 8 directions at intervals of 360° within 360°.
The fractional dredge pump can transport light abrasive slurry as well as strong abrasive slurry.
When the pump speed is lower than the maximum transfer 60%, the pump outlet flow rate is less than 8 m / s can deliver strong abrasive slurry
Conversely, when high speed, high lift and large flow rate, transport light abrasive slurry
note
Strong abrasive slurry refers to concentrate of black colored mine, slurry of solid particles with tailings >0.1mm, volume concentration >5%, and power plant slurry
Light abrasive slurry refers to slurry with particle size <0.1mm, volume concentration <5%, slurry of coal slurry and mortar of power plant
AHR is suitable for conveying small particle size, no sharp angle particles and high concentration slurry, and can also transport corrosive slurry
DOH type dredge pump, there are two types of shaft seals, such as packing and impeller. Users can change to mechanical seals with special requirements.
There is also a special fractional dredge pump G/GH type gravel pump, which is a horizontal, single-shell, axial suction centrifugal dredge pump.
The pump body cover is connected by a special clamping device, so that the pump outlet can rotate freely within 360°.
DOS type gravel pump generally transports large abrasive and strong abrasive slurry with good cavitation performance and large suction capacity. It is widely used in the case of high requirements for pump cavitation, and is often used in dredgers. Dredging, dredging rivers, power plant ash and the transportation of explosions in front of the ironworks
DOS pump has three sealing forms: packing, impeller and mechanical seal.
