What is the working principle of a reciprocating pump?
Introduction of Reciprocating Pump: Reciprocating Pump is a Positive Displacement type pump that works on the principle of movement of the piston in forwarding and backward directions whereas the Centrifugal pump uses the kinetic energy of the impeller to supply the liquid from one place to another place.
Which is reciprocating pump?
A reciprocating pump is a class of positive-displacement pumps that includes the piston pump, plunger pump, and diaphragm pump. Well maintained, reciprocating pumps can last for decades. Unmaintained, however, they can succumb to wear and tear.
What are the main components and action of a reciprocating pump?
A hollow cylinder made of steel alloy or cast iron. Arrangement of piston and piston rod is inside this cylinder. Suction and release of liquid is takes place in this so, both suction and delivery pipes along with valves are connected to this cylinder.
Where is reciprocating pump used?
Incorporating reciprocating pumps results in repeatable and precise mechanical operations. Industries that commonly use reciprocating pumps include: Oil and gas: Oil and gas industry applications include disposal, offshore oil, production, injection, feed, charge, steam generators, mainline, and field gathering.
What is application of reciprocating pump?
Applications of Reciprocating Pump: 1) It is used in vehicle washing centers. 2) It is used in small hand-operated pumps such as cycle pumps, football pumps, etc. 3) It is used as an important part of the hydraulic jack. 4 )It is commonly used in gas industries. 5) It is also used in oil refineries.
What are the advantages and disadvantages of a reciprocating pump?
Advantages and Disadvantages of Reciprocating Pump
- This pump is self-priming – Not require filling the cylinders by starting.
- This pump can work in wide pressure range.
- Priming is not necessary in pump.
- Provide high pressure at outlet.
- Provide elevated suction lift.
- They are use for air also.
How are reciprocating pumps classified?
Classification of Reciprocating Pumps A piston or plunger that reciprocates in a cylinder. Suction and delivery pipes with non-return valves, a suction valve in the suction pipe and a delivery valve in the delivery pipe. Crank and connecting rod mechanism.
How do you start a reciprocating pump?
How to Start A Pump?
- Line up the pump seals coolant.
- Line up the pump casing jacketing cooling tower.
- Check the bearing oil level.
- Open the pump suction level fully.
- Remove the vapour / air from the pump casing.
- If it is reciprocationg pump keep suction and discharge valve full open.
What is the efficiency of reciprocating pump?
The overall efficiency of a reciprocating pump unit is generally above 85 percent throughout its full operating range (see Figure 4).
What is the disadvantage of reciprocating pump?
Disadvantages of Reciprocating Pump: 1) The pump is very costly (Capital cost is high). 2) Viscous liquids are difficult to pump using a reciprocating pump. 3) The maintenance cost of the pump is very high as there is a large number of parts. 4) The flow rate is less.
What type of flow does the reciprocating pump have?
Explanation: The reciprocating pump has a continuous flow. It has a constant discharge even if head on the delivery side varies.
What are the parts of a reciprocating pump?
A reciprocating pump consists of several parts and those are: 1 Suction Pipe 2 Suction Valve 3 Delivery Pipe 4 Delivery Valve 5 Cylinder 6 Piston and Piston Rod 7 Crank and Connecting Rod 8 Strainer 9 Air Vessel
What are the advantages of reciprocating pump?
There are four major advantages of a Reciprocating Pump and those are the following: High pressure is obtained at the outlet. The priming process is not needed in this pump. Reciprocating Pump provides high suction lift.
Are reciprocating power pumps suitable for seawater reverse osmosis?
