Marine Power Plant Diesel Engine Fuel Oil Handling System
Disc Separator 5000 LPH
Description:
1. Model PDSD5000-H separator is mainly used to remove water and mechanical impurities from fuel oil, lubricating oil, and other mineral oil in marine diesel engine units and land-used diesel generator units of power stations so as to reduce wear of the diesel engine and other machine and prolong engine life. The model is also used to separate two unsolvable liquids with different specific gravity or remove a small number of solid particles from a liquid.
2. The machine adopts automatic control, it has the advantages of high efficiency, low oil consumption, convenient operation, and economic maintenance cost.
3. The clear oil and dirty water are pumped out by a centripetal pump, and the sludge is discharged automatically and fully.
4. The machine is one kind of rotary machine with high speed, After accurate dynamic balancing, it can run for a long time with low vibration, safety, and security.
5. The design, product, and acceptance are conformed to the standard of GB/T5745 “Marine Disc Separator”.

Value Analysis:
1. Peony adopts SKF bearing, which is consistent with Alfa, Westfalia.
2. Alfa and Westfalia only provide clients with the bearing and the gear in the overhaul package(need to buy separately) while Peony has a more sufficient attachment supply.
3. Peony never reduces the number of spare parts and tools for users buying many sets of the same model machine. (unless the customer put forward in specially).
4. Regular spare parts are all in stock in Peony’s company.

Principle and structure
The disc separator is the vertical centrifuge. The drum is installed on the upper side of the vertical shaft. Driven by the motor, it will rotate at a high speed through the gearing. Inside the drum, there is a group of dish parts overlaying each other – a disc. There is a very small gap between the disc. The suspension (or emulsion) is fed into the drum through the inlet in the middle of the drum. When the suspension (or emulsion) flows through the gap between the disc, under the action of the centrifuge, the solid particles (or droplets) go down to the disc in the formation of sediment (or liquid layer). Along the disc surface, the sediment slides out of the disc and accumulates at the part with the largest diameter inside the drum. After the separation, the liquid is discharged out of the drum from the drain outlet. The role of the disc is to reduce the sediment distance of solid particles (or droplets) and enlarge the sediment area of the drum. With the disc inside the drum, the capacity of the separator is improved greatly. The solid gathering inside the drum is manually removed by taking apart the drum after power off or discharges from the drum through the slag-off part with the separator power on.
