Where are reciprocating positive displacement pumps used?
Reciprocating positive displacement pumps are typically used for applications that need to maintain low flow rates against high resistance. Some may be used to pump highly viscous and heavy fluids, like sludge and slurry. Diaphragm valves are often used when pumping toxic and hazardous fluids.
What is reciprocating positive displacement pump?
Reciprocating positive displacement pumps A Reciprocating Positive Displacement pump works by the repeated back-and-forth movement (strokes) of either a piston, plunger or diaphragm (Figure 1). These cycles are called reciprocation.
What is an example of a positive displacement pump?
Examples of rotary positive displacement pumps are gear pumps, screw pumps, progressive cavity pumps, rotary piston pumps, water ring pumps, rotary vane pumps, roller vane pumps and peristaltic pumps.
Where are reciprocating pumps used on ships?
Reciprocating pump are very important part of the ship’s machinery and any other industry which is present in the world. High pressure is the main characters of this pump, and this high pressure output are being used in places like starting of the engine or you can say the building of pressure in the fluids.
What are the two types of positive displacement pumps?
Positive displacement pumps, which lift a given volume for each cycle of operation, can be divided into two main classes, reciprocating and rotary. Reciprocating pumps include piston, plunger, and diaphragm types; rotary pumps include gear, lobe, screw, vane, and cam pumps.
What are the applications of reciprocating pump?
Uses of Reciprocating Pump
- Oil drilling operations.
- Pneumatic pressure systems.
- Light oil pumping.
- Feeding small boilers condensate return.
What pumps are used onboard ships?
Rotary Types Of Displacement Pumps Are Commonly Used On Board Ships In Place Of Reciprocating Pumps. A Rotary Pump Continuously Scoops The Fluid From The Pump Chamber By Means Of Gears Or Screws, Or Vanes Etc.
Which type of pump is positive displacement pump?
Positive-displacement pumps can be divided into two major types: rotary and reciprocating. All rotary pumps use some form of rotating element, such as gears, vanes, or lobes to increase the discharge pressure. Reciprocating pumps use pistons or wobble plates to increase the pressure.
What is HPP pump?
The high-pressure pump is a centrifugal pump with a head of between 200 and 1200 m, which is used, for example, in pressure booster systems, Low-pressure, medium-pressure or super-pressure pumps are used for other areas of application.
Where is reciprocating pump used in ship?
Uses of reciprocating pump The lubricating pump is a reciprocating pump and it supplies the lubrication oil to the main engine. The main bilge suction pump is also a reciprocating pump. For ballast they are sometimes used.
