machinery problem. We intend to do a project on “Vibration analysis of centrifugal pump at BPCL Kochi Refinery”. The vibration analysis we have done is a part of predictive maintenance on rotary equipments. This technique is mainly used for the improved performance of equipments. Using this we can predict the condition of internal parts of the equipment. We are mainly dealing with the vibration analysis of centrifugal pump‚ compressors and motors. It includes typical causes of vibration like misalignment

You could also use carbon dioxide or sulfur hexa-fluoride between glass. Another type of window that is used commonly to keep the home cool is tinted glass. Tinted glass and tinted window films are used on buildings to reduce heat gain through windows. Advancements in tinted glass have now allowed us to make the glass appear just as a regular window that

AUTOMATIC WATER PUMP CONTROLLER The automatic water pump controller is used to control the water pump motor. The motor gets automatically switched on when water in the overhead tank (OHT) falls below the lower limit. Similarly‚ it gets switched off when the tank is filled up. Built around only one NAND gate IC (CD4011)‚ the circuit is simple‚ compact and economical. It works off a 12V DC power supply and consumes very little power. The circuit can be divided into two parts: controller circuit and

consider a multiple pump system to meet the design requirements. Two typical options include parallel and series configurations of pumps. Specific performance criteria must be met when considering these options. Given a piping system which has a known design flow rate and head requirements‚ Qdes‚ hdes‚ the following pump selection criteria apply. Pumps in Parallel: Assuming that the pumps are identical‚ each pump must provide the following: Q(pump) = 0.5 Qdes h(pump) = hdes Pumps in Series: Assuming
