Management of change (MOC) Management of change (MOC) is that any measures or minor changes in the process plant are called management of change. There are many types of management changes that occur in a plant, like changes in P&ID, changes in isometric drawing, changes in equipment design, changes in operating procedures, changes in inspection […]
Bearing The term bearing comes from the bear, a bearing is a component that supports load while permitting relative motion between two parts of the machine. Bearing is an important part of a machine that carries the load, reduces friction, and gives a smooth operation. The selection of bearings is based on the requirement of […]
Cavitation in the centrifugal pump Cavitation in centrifugal pump is the formation of bubbles, because the liquid suction pressure fall below its vapor pressure or any other reasons. There are many cases of cavitation in centrifugal pumps, these are discussed below. The formation of the bubble mostly happens in a pipe inside, equipment, valves, and […]
NPSH (Net positive suction head) What is NPSH? NPSH (net positive suction head) is the difference between suction pressure and lowest pressure inside the pump or system. By the use of the Bernoulli theorem, calculated if the suction pressure is greater than vapor pressure, then the risk of cavitation is negligible, but in other cases, […]
FMECA (failure mode effects and criticality analysis) The (FMECA) failure mode effects and critical analysis method is used to identify and prioritize failures that could occur in the processing system or particular equipment. It is a part of FMEA. With the help of failure mode effects and criticality analysis to identify what types of maintenance […]
What is a gasket? A gasket is a mechanical seal that is placed between two or more mating surfaces to prevent fluid or gas leakage. Gaskets can be made from a variety of materials, such as rubber, metal, cork, or paper, depending on the application requirements. They are designed to conform to the irregularities of […]
Condition-based maintenance (CBM) Condition-based maintenance is also called (predictive, proactive) in which perform the activity depends on the condition of the equipment. To achieve the maximum production goal and avoid the unexpected equipment failed. Condition-based-maintenance Condition-based maintenance has two parts condition monitoring maintenance reliability-centered maintenance When Condition-based maintenance (CBM) should be needed and when […]
What is the role of a maintenance engineer? The main role of a maintenance engineer is Maintaining the equipment. Reduce maintenance costs. Keep the plants running at reliability and at full capacity. Reduces resources like human effort and assets. Inspection of the equipment on a routine basis. Analysis of the criticality of equipment on the […]
Preventive maintenance Preventive maintenance is a proactive type of maintenance in its action was taken before breakdown maintenance and prevented failure of machines and also saves from equipment downtime. Preventive maintenance can be done like weekly, monthly, quarterly, half-yearly, yearly some time also use a quote (prevention is better than cure) for […]
Breakdown maintenance Breakdown maintenance is a prominent approach to equipment maintenance that primarily centers around resolving issues as they arise, rather than implementing preventive measures. While this strategy may offer certain advantages, it also presents several drawbacks that can impact operational efficiency and overall productivity. In this comprehensive exploration, we delve into the benefits and […]
Introduction of compressor A compressor is a mechanical device that is designed to increase the pressure of a gas by reducing its volume. It is used in a wide range of industries, including manufacturing, chemical processing, oil and gas production, and refrigeration. Compressors come in various types and sizes, ranging from small portable units to […]
Mechanical Equipment Mechanical equipment in a chemical plant is used for a variety of operations that are involved in different stages. This equipment is used to conduct a variety of chemical processes and support production. Here are several links to some of the main mechanical equipment that may be used in a chemical plant. There […]
