Centrifugal Tutorial Centrifugal Pump A centrifugal pump is one of the simplest pieces of equipment. Its purpose is to convert energy of an electric motor or engine into velocity or kinetic energy and then into pressure of a fluid that is being pumped. The energy changes occur into two main parts of the pump‚ the impeller and the volute. The impeller is the rotating part that converts driver energy into the kinetic energy. The volute is the stationary part that converts the kinetic energy into

well. This can be achieved by various drilling techniques. In this chapter rotary drilling rigs will be examined. These are‚ in practice‚ the only ones operating today in the field of hydrocarbons exploration and production. The drilling rigs used on land are complexes of mobile equipment which can be moved in reasonably short times from one drill site to another‚ drilling a series of wells. In particular‚ the typical rotary rig for drilling onshore medium to deep wells‚ indicatively more than 3‚000

mechanical type‚ the screw rod is actuating the movable jaw. One end is connected to the movable jaw and it passes through a fixed type nut. When we rotate one end of the screw rod it will rotate in the nut and in turn moves the movable jaw. Here the rotary motion is converted into reciprocating motion. In Hydraulic type’s one end of the piston rod is connected to the movable jaw and the piston slides in the cylinder. Here the hydraulic fluid actuates the movement of the piston; this in turn actuates

launder. Through the above process‚ the washing function is finished. The clean sand and stone is lift up by vane. When it goes up slowly‚ the water begins to drop through the mesh and fall back in the washing launder. On one hand‚ water is removed from the sand and stone; on the other hand‚ the water can be fully used. Finally‚ the sand and stone goes to the out launder from the rotary impellor to finish the washing task. jaw crusher:http://www.jawscrusher.org impact crusher:http://www.impactscrusher

instrumentation have problems. Determine the flow of pipeline. Check whether there are ore to prevent the ball mill running. Check the ring gear and pinion gear case with or without abnormal noise.The order of starting ball mill is: first start the ball mill oil pump. When the oil pressure reaches 1.5 ~ 2.0 kg / cm2‚ it is allowed to start the ball mill‚ and then start the grading machine. All are functioning properly‚ and then start grinding. In operation‚ we must always pay attention to bearing temperature

IMPACT OF a jet ABSTRACT The objective of this experiment is to determine the force exerted by a jet of water on vanes of various shape.Three different shape of vanes;flat plate‚conical cup‚and hemispherical cup are used for this experiment.The results obtain from the experiment are then used to compare with the theoretical results.Force generated on the surface of vane depends on the rate of change of momentum and it can be calculated by recording the time taken for water to reach a certain

Results and discussion 5 4. Conclusion and Recommendations 8 References 8 Appendix 9 Abstract The experiment was conducted to find the impact of water on different types of vanes‚ it consists of 3 types the flat plate‚ conical cup and the hemispherical cup. Forces are generated by jet of water impacts the vanes that produces various angles of deflection. In the end the slope calculated was used to compare with the theoretical slope and the deviation slope was calculated. 1.0 Introduction
