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 […]
Mechanical seal A mechanical seal is a vital device employed to effectively prevent the leakage of liquid from the inside casing to the outside, specifically by creating a seal between the static and rotating components. These seals find extensive usage in centrifugal pumps and various other equipment. The classification of mechanical seals is based on
Troubleshoot of centrifugal pump When troubleshooting a centrifugal pump, it’s important to follow a systematic approach to identify and resolve the problem. Here’s a general troubleshooting guide for centrifugal pumps: Start with Safety: Ensure that the pump is turned off and disconnected from the power source before beginning any troubleshooting activities. Follow all appropriate safety
Type of pumps There are many different types of pumps that can be used for a variety of applications. From electric and air-operated pumps to manual and hydraulic ones, each has its own characteristics that make it suitable for certain tasks. In this guide, we’ll discuss the different types of pumps, their features, and how
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 Turbine? The turbine is a mechanical device which converts the kinetic energy into mechanical power by the help of buckets and blades. It is also called energy-producing devices. When fluid enters through the nozzle and strikes the bucket or blade, then the rotor is started rotating because blades or buckets are fixed on
Centrifugal pump It is a mechanical device that is used to transfer the fluid from one place to another place with the help of a rotating impeller. The rotating impeller converts kinetic energy to hydraulic energy with the help of pump casing. Centrifugal pumps work on the principle of centrifugal force. When the impeller starts
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
