Dredge Pump Types:
1.Single-Walled Dredge Pump
2.Double-Walled Dredge Pump
3.Underwater Dredge Pumps
Technical Features and Performance
1.The whole construction is suitable for dredging ship.
1.1 Reliable and simple structure.
The 200-1000WN dredging pump is designed into double suctions single-stage, single suction cantilever horizontal structure with bracket, which is lubricated by forced diluted lubricant. The safety and reliability of double pump casing make the liner used up until it is nearly broken. Even if the liner broken, water cannot flow into pump casing.
1.2 Easy disassemble and convenient installation maintenance.
2.Dredging performance is excellent.
2.1 Good NPSH
2.2 Strong through-out capability, wide application.
2.3 The curve of performance decreases sharply.
3.Excellent anti-wear performance, long service of wet parts.
4.A little hydraulic loss, high efficiency, low power consumption.
5.Reliable shaft sealing without leakage.
The 200-1000WN dredging pump adopts spiral sleeve L sharp rubber sealing device that consists of three L sealing ring and one special thread bearing shaft sleeve.
Note: Dredge pumps can be offered according to customer’s requirement.
Ship Proportions
L/B
The ratio of the length and breadth can differ quite dramatically depending on the type of vessel. Common values:
Passenger Ships |
6-8 |
Freighters |
5-7 |
Tug Boats |
3-5 |
A larger L/B value is favorable for speed, but unfavorable for manoeuvrability.
L/D
The length/depth-ratio. The customary values for L/D varies between 10 and 15. This relation plays a role in the determination of the freeboard and the longitudinal strength.
B/T (T=Draught)
The breadth/draught -ratio, varies between 2.3-4.5. A larger breadth in relation to the draught (a larger B/T value) gives a greater initial stability.
B/D
The breadth / depth ratio, varies between 1.3 and 2. If this value becomes larger, it will have an unfavorable effect on the stability (because the deck will be flooded when the vessel has an inclination) and on the strength.
