Fluid Mechanics & How it Relates to Mechanical Engineering
Viscosity Measurement Equipment This article provides an introduction and description to some of the different types of viscosity measurement devices used in the field, factory, and laboratory, and how to select which one to use.
Care and Maintenance of Chicksan Valves and Swivel Joints Chicksan loading arms were developed in the fifties to load and discharge oil tankers. Their main features are unique swivel joints and isolating valves fitted each side of a powered emergency release system. Chiksan arms are also used in the chemical, oil refining, and offshore industries.
Desalination Technologies Many countries throughout the world are currently experiencing severe water restrictions due to drought conditions.
To alleviate this, modern desalination plants are being developed with a view to providing drinking, irrigation and process water from seawater using for example Forward Osmosis.
Fluid Pumps: Classification and Types Classification of fluid or hydraulic pumps is based on fluid flow pattern through pumps and fluid supplied by pumps. Pumps can be classified as intermittent flow Positive Displacement Pumps and continuous flow Roto-Dynamic or Turbo Pumps. Read more on criteria of classification and different types.
Types of Reciprocating Positive Displacement Pumps: Diaphragm Pump Diaphragm Pumps have a diaphragm as the reciprocating part. The reciprocation of this diaphragm produces the pumping action of the diaphragm pump. The diaphragm can be actuated by liquid or air. Accordingly pumps are called as hydraulically operated or air operated diaphragm pumps.
Types of Reciprocating Positive Displacement Pumps: Piston Pump Reciprocating pumps can have two types of reciprocating part, a piston or a diaphragm and based on this, reciprocating pumps can be piston or diaphragm pumps. Each type has different features suitable for specific applications. Read in this article construction, working and variants of Piston Pumps.
Reciprocating Positive Displacement Pumps Reciprocating Positive Displacement Pumps has reciprocating parts to pump fluid. During one direction of motion of the reciprocating part fluid or liquid is taken inside and during the other opposite direction of motion fluid is pushed out. Reciprocating part can be a piston or a diaphragm.
Reliable Lubrication A lubrication system is essential for wear prevention in machine parts. The hydraulic oil forms a thin film between the moving parts that prevents their direct contact with each other. The hydraulic oil viscosity should be suitable for the application.
