( PART- 01)
To keep the machinery running and well almost all industries need mechanical Engineers. Mechanical Engineer works in different positions and departments respectively like Assistant Engineer, Engineer, Chief Engineer, Managerial level and Machine maintenance, Utility maintenance, Product Research & Development, Workshop, Operation etc. job in Studying various Bangladeshi industries job responsibilities requirement a short summary for preparing a job interview for a mechanical engineer is listed below.
> Valves : Different types of manual, Automatic ( Pneumatic, Electric Operated) valves used in Water, Steam, other Hydraulics, and Pneumatic line. Example: Globe valve, Butterfly valve, Check valve, gate valve etc. Applications of the valves, maintenance parameters etc. Other topics related with valves like Strainer, Reducer, Flanges, bend, elbow , Union , etc. are required to learn with their applications.
> Pumps: Pump is a very important equipment in modern industries. As a mechanical engineer once should know details of pump including their operation, maintenance and applications. Different pumps are used in different applications in water, and other hydraulic product line to convey them in desired destination. Centrifugal and Positive displacement pump ( Lube pump, Progressive cavity pump, Screw pump, gear pump , Piston pump etc.) are widely used in modern factory operations. pump seal is one of the most important things to understand .
> Conveyor : Conveyor system is used to carry the finished product as well as other products to one place to another. Conveyor system comprises with conveyor belts, motor, pulley/chain drive, conveyor frame etc. Types
> ETP : Effluent Treatment Plant is one of the waste treatment method which is designed to purify industrial waster water for its reuse and safe water to environment . The PH, DO, COD , BOD , TDS parameters and the terms used for.
> WTP: Water treatment Plant is the process used in industry to improve quality of water to use in the desired end use application. Widely improved water is used for Boiler, Process area etc.
> TPM: Total Productive Maintenance is a team based system which constantly improve the effective of machinery equipment for increasing plant and equipment reliability . Main pillars of TPM are Focused maintenance, Autonomy, Quality maintenance, Planned maintenance, Safety , health and environment, Training and education .
> Compressor: Compressor is one the most important utility equipment used in different industries. Types of Compressor, Compressor regular maintenance, troubled maintenance, Spare parts etc are necessary information required while preparing for the interviews.
> Boiler: Boiler is another most important utility equipment in various industry. Generally Boiler is used to get steam for using in different application . Steam has direct and indirect use in the plant. Boiler mountings, accessories , Burner system, regular check list, maintenance schedule, Boiler water parameters are important topics. Condensate recovery system , Exhaust gas boiler , are also related with boiler.
> Chiller: For process area and machinery uses Chiller is used to maintain to control the room temperature. Air Handling Unit, Chiller regular check list, regular maintenance , Chiller types, Air Handling Unit (AHU) , diffuser, Refrigerant types and characteristics etc are important topics. Working principle of Chiller, Block diagram , etc are theoretical topics .
> Cooling Towers: Cooling tower is used to cooling the water of chiller, hydraulic system etc. Different types of cooling towers are used in different uses. Cooling tower maintenance list, cooling tower types, cooling tower load calculation are important topics.
> PLC : Every modern industries are now using PLC based machinery for smooth , accurate and less time consumption. How PLC works , troubleshooting knowledge will enhance job prefer-ability.
> QMS : Quality Management System, ISO 17025:2017 documentation list .
