4000 LPH Automatic Marine Oil Purifier Disc Stack Centrifuges Separator
Description
1.Model PDSD4000 separator is mainly used to remove water and mechanical impurities from diesel oil, lubricating oil and other mineral oil in marine diesel engine unit and land-used diesel generator unit of power station so as to reduce wear of the diesel engine and other machine, and prolong engine life.
2.The model is also used to separate two unsolvable liquids with different specific gravity or remove small amount of solid particle from liquid.
3.The machine adopts automatic control, and has the advantages such as high efficiency, low oil consumption, convenient operation and economic maintenance cost.
4.The clear oil and dirty water are pumped out by centripetal pump, the sludge is discharged automatically and fully.
5.The machine is one kind of rotary machine with high speed. After accurate dynamic balancing, it can run for long time with low vibration, safety and security.
6.The design, product and acceptance are conformed to the standard of GB/T5745 Marine Disc Separator.
Principle and structure
Disc separator is 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 – disc. There is very small gap between the disc. 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 discharge 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.
Advantages
1. Automatic piston type slag removal
2. Modular design
3. Automatic operation
Installation Notice
1. When install the separator, make sure there is enough space around the machine for its maintenance and repairing.
2. The foundation must be firm,plan and leveling.
3. All the pipes connecting with separator should be flexible.
4. The operation water of the separator must be soft water, the pressure of which is between 0.025MPa and 0.03MPa
