How To Overhaul Fuel Oil Purifiers On Merchant Ships

By Engr Matahula, Smart Pwashemeno Overhauling fuel oil purifiers on merchant ships typically involves a series of maintenance procedures to ensure their optimal performance. Here is a general guideline for overhauling fuel oil purifiers: Preparation: Obtain the necessary tools and spare parts for the overhaul. Review the manufacturer's instructions and guidelines for the specific purifier model on your ship. Ensure that you have appropriate personal protective equipment (PPE) for the task. Shutdown and Isolation: Shut down the purifier and isolate it from the fuel system by closing the relevant valves. Drain any remaining fuel and ensure the system is depressurized. Disassembly: Carefully disassemble the purifier according to the manufacturer's instruc...

All About Boiler Water Blow Down And Procedures For Marine-Boilers

What is boiler water drum blow down in marine boilers? In marine boilers, the boiler water drum blowdown refers to the process of removing a portion of the water contained in the boiler drum to control the concentration of dissolved and suspended solids. Blowdown is necessary to maintain the desired water quality and prevent the buildup of harmful impurities in the boiler. During boiler operation, water is continuously evaporated to produce steam, leaving behind dissolved and suspended solids. If these impurities are allowed to accumulate, they can cause various problems such as scale formation, corrosion, and reduced heat transfer efficiency. Blowdown helps to remove these impurities and maintain optimal boiler performance. The blowdown process involves opening a valve or a blowd...

Mechanical Seal Vs Packing Gland: What Is The Difference?

A mechanical seal and a packing gland are two different methods used to create a seal in various types of machinery and equipment. Here's a comparison between the two: Function: Mechanical Seal: A mechanical seal is a device designed to prevent leakage between rotating and stationary parts in a system, such as pumps, compressors, or mixers. It consists of two flat faces, one stationary and one rotating, held together under pressure by springs or other means. Packing Gland: A packing gland, also known as a stuffing box, is a traditional sealing method that uses packing material, such as braided or molded fibers, placed around a rotating or reciprocating shaft. It is compressed by a gland follower or a packing nut to create a seal. Sealing Efficiency: Mechanical Sea...

Understanding Oil Purifiers and Their Need On Ships

by Engr Matahula, Smart Pwashemno on Oil Purifiers Oil purifiers, also known as oil centrifuges or oil separators, are essential equipment on ships for maintaining the quality of lubricating and fuel oils. They are used to remove impurities, contaminants, and water from the oil, ensuring that it meets the required standards for efficient operation of ship machinery. On ships, oil purifiers are primarily used for two main purposes: Lubricating Oil Purification: Lubricating oil is used in ship engines, turbines, and other machinery to reduce friction and wear between moving parts. Over time, the oil gets contaminated with particles, sludge, and water, which can lead to reduced lubrication efficiency and increased component wear. Oil purifiers are employed to remove these contam...

Function Of Steering Gear Systems In Seagoing Ships

By Engr Matahula, Smart Pwashemeno Steering Gear Systems In Seagoing Ships Steering gear systems are crucial components of seagoing ships, as they allow for the control and maneuverability of the vessel. These systems are responsible for changing the direction of the ship by altering the position of the rudder or rudders. Let's delve into the basics of steering gear systems in seagoing ships. Types of Steering Gear Systems: Mechanical Systems: Traditional ships used mechanical steering gear systems, which involved a direct mechanical linkage between the steering wheel on the bridge and the rudder. This system required physical force to move the rudder and was commonly found in older vessels. Hydraulic Systems: Most modern ships employ hydraulic steering gear systems. These s...

Difference Between Brake Power And Indicated Power Of Internal Combustion Engine

The power output of an internal combustion engine is a crucial factor in determining its performance. Two of the most commonly used methods for measuring this power output are indicated power and brake horsepower. First of all, when we say indicated power it is the total power produced within the cylinder in one complete cycle without considering any losses, and on the other hand, the amount of power available at the dynamometer is called brake power. Let’s take a closer look at the difference between indicated and braking power. Brake power is usually less than indicated power. The difference between indicated and brake power is called friction power. The primary goal of Internal combustion engine design and development is to lower production costs while increasing efficie...
