An Overview of Centrifugal Pumps
Centrifugal pumps are widely used as industrial pumps and also in cooling, water control and chemical processing systems. They are preferred over other types of pumps since they are simple, reliable and efficient. Centrifugal pumps transfer energy to the fluid bei......
Economical processing accuracy for surface processing, cylindricity, parallelism, end face runout and perpendicularity, coaxiality
Introduction
Cylindrical surfaces are important components of many precision machines. As each component of the machine is made of the highest standards and accuracy, each component needs to be processed according to sychronized machining standards. In order to achive perfect accuracy, cylindric......
Bearing running speed
Bearings are one of the most important components used in machinery and equipment. It is a device used to support, guide and reduce friction between moving parts. Although there are different types of bearings; rolling, thrust, linear and journal bearings all have speed restrictions that must be a......
There are several kinds of bearings installed on the centrifugal compressor
Centrifugal compressors are typically mounted with two or three main bearings. The main bearings support the main drive shaft, which cycle pumps gas compressor impellers that are arranged in series. The bearing arrangement provides a balanced system, which helps minimise vibration, increase effici......
