How to select the type and place your order:
Where heavy oil cabinet of daily use has its bottom level vertically higher by 2 or over 2m than the bottom level of oil supplying unit installation, one may select the two-pump type oil supplying unit, as this unit has low pressure for the air depletion in oil mixing, which reduces the evaporating temp of the light substances and water content in the fuel oil in high tempt oil return pipe. Two-pump type suits fuel oil below 1500s by Redwood viscosity scale.
The tonnage of the vessel, or container number, type of vessel, kind of fuel oil the vessel is going to use, location of shipyard where the vessel is built, and its main routes of voyage
Number of main engines or aux engines that consume heavy oil, manufacturer of the engine, their power and routine operating load, low speed engine or medium speed engine
Setup of the heating equipment on board, whether or not equipped with steam/heat conducting oil fuel boiler, waste steam boiler, hot water boiler, waste gas heat conducting oil boiler or waste gas from fuel oil combination boiler etc. Parameters such as steam evaporation volume and evaporating pressure
Power supply mode: normally 380V/50Hz/3Φ; in special cases where 440V/60Hz/3Φ、220V/60Hz/3Φ or others are used the relevant situation will have to be given.
In principle it is not recommended to use the main heating setup as electrical heating of the oil supplying unit. It is selected only when there is no other heating source in the cabin. However, electric heating can be an aux standby source of heat.
Layout of machine cabin and oil cabinets (oil tank, sedimentation cabinet, daily use cabinet and dirty oil cabinet)
You will please provide above mentioned plant conditions for us to give reference in type selection of purpose of optimum working conditions.
Two choices are available of oil supplying unit structural layout: 3-D individual cabinet control mode and plane integrated control mode. Unless customer specifies otherwise, control setup will be flat integrated mode.
A comparison between the flat integrated control mode and the 3-D individual cabinet control mode
Compared with 3-D individual cabinet control mode, the flat integrated control mode has the following advantages:
type
item |
flat integrated control |
individual cabinet control |
basic setup |
fully identical |
fully identical |
equipment layout |
basically a planar layout |
basically a 3-D layout |
operability |
simple and clear by one look, one can learn to operate in the shortest time |
equipment maintenance somewhat more complicated, operation is relatively more difficult because of the seemingly complicatedness |
maintenance |
easy operation and maintenance, operators/maintenance crew are not usually seen as dirty or smeared |
less easy of operation and maintenance. In case pump above gets leaky, the equipment and pipeline below may get damaged. |
repairs |
open and flat layout makes it easy to maintain, replace or dismount |
Because of frames around operating, maintenance, repairs, replacing or dismounting are not very easy |
gravity center and vibration characteristics |
Low gravity center lowers the free end, thereby greatly reducing vibration and enhancing the reliability of the equipment |
Comparatively higher gravity center and greater vibration make stability and reliability somewhat inferior |
electrical layout |
adoption of independent branch lines greatly reduces the probability of electrical failure and makes it a lot easier for service and maintenance |
Concentrated cable laying in the framework and spread out electrical cabinets make wire connections more complicated, repairs and removal of cable/wire more difficult, resulting in less good reliability. |
outer dimensions |
An additional 250—400 lengthwise, with identical width and height |
comparatively less room taken |
lifting and installing |
comparatively difficult to lift and move, parts/components may get damaged |
easy and convenient to lift and handle, not liable to damage parts and components |
appearance |
simple and quietly efficient |
fullness and elegance |
man/machine functionality |
a more human product, easy to operate |
less easy |
Concluding from above, the company recommends the flat integrated control oil- supplying unit. Where customer so requires, the company will also provide 3-D individual cabinet control oil supplying unit.
