Champion Filters and Strainers on Ship:Types and Uses
For
a prolonged safe, trouble free and efficient operation of machinery and system on board ship, it is important that there is proper maintenance, record of correct parameters and prevention of impurities from entering the systems. The first and second points are a part of routine duties; however for preventing impurities from entering, it is important that every system is incorporated with filters and strainers which help in removing contamination from the system.
Filter & Strainer on Ship
Filter is a fine mesh screen which is used to remove impurities from oil, water and air on ship. Filters are mounted in pairs as a duplex system so that one can be used and other is kept on stand by at a time. Filter can be used both in low pressure (suction) and discharge (high pressure) side of the system and is used to remove the smallest part of dirt which is carried away in the system. The cleaning frequency of filters depends upon the type of the filter and is decided by the manufacturer. The schedule is normally included in the planned maintenance system on board.
Strainer is a type of filter used mostly on low pressure or suction side and is used to remove large contamination particles from the system. This is because the mesh screen openings in the strainer are bigger in size and are similar to those of coarse filter. If the suction condition is critical, then the strainer can be fitted on the discharge side. This purely depends upon the make and recommendation of the manufacturer. Normally strainers are cleaned whenever they are opened or when the pressure drop on the filter side is high.
Type of Filters Used on Ship
Types of filters depending upon the Media
1) Hydraulic Filter: Hydraulic filters are very useful for removing solid contamination from lube and fuel oil systems of marine machinery. Without filters in the lube or fuel oil system, the machinery internal parts, bearings, piston, rings, liners etc. can get damaged, which will result in inefficient working of the machinery. Different applications of hydraulic filters are:
a) Fine Mesh Screen Filter: It is the most commonly used filter in lube and fuel oil systems on board. It can be used both on suction and discharge side of the system. It is normally used in cylinder lube oil line, main engine and auxiliary engine fuel oil line & diesel oil line, boiler fuel oil line and in different lube oil systems on board etc.
b) Magnetic filter: This normally consists of filter elements which are magnetic in nature and which help in catching fine metal or ferrous particles that run in the system. These elements are surrounded by a basket screen which also acts as a filter and simplifies the cleaning of the filter. Magnetic filters are used in lube oil system.
c) Auto Back Wash Filter: In auto back wash filters, when the pressure difference increases, an indication of filter getting clogged, the auto system cuts-off the filter and opens the bypass. The auto wash takes place with the help of an electric motor connected to a shaft which cleans the filter. During this operation, the drain of the filter gets open.
d) Centrifugal filter: As the name suggests, these filters work on the principal of centrifugal force removing high density fluids and impurity from the oil. It is normally used for lube oil systems. Most of the Auxiliary engines have attached centrifugal filters.
