In what conditions we use a reciprocatory pump?
Reciprocating pumps are used most often for low-capacity, high-pressure service. The initial cost of small reciprocating pumps is competitive with centrifugal pumps.
Where do we use centrifugal pump?
Common Industrial Centrifugal Pump Applications Water supply for residential areas. Fire protection systems. Sewage/slurry disposal. Food and beverage manufacturing.
Where reciprocating pump is used in ship?
Reciprocating pump is the term that is used for the pumps that perform to and fro motion to displace fluid from suction line to discharge line. Reciprocating pumps move water or other liquids by a plunger or piston that travels back and forth inside a cylinder. Under Reciprocating pumps comes.
What types of fluids are pumped by reciprocating pump?
Air-operated piston pumps use a reciprocating piston and check mechanism to produce fluid flow and pressure. They can produce fluid pressures in excess of 6,500 psi, so they’re popular for pumping viscous fluids such as sealants, adhesives, inks and lubricants.
Why centrifugal pump is called Rotodynamic pump?
A rotodynamic pump is a kinetic machine in which energy is continuously imparted to the pumped fluid by means of a rotating impeller, propeller, or rotor, in contrast to a positive displacement pump in which a fluid is moved by trapping a fixed amount of fluid and forcing the trapped volume into the pump’s discharge.
What are the applications of single acting reciprocating pump?
The applications of Reciprocating Pump are as follows.
- Gas industries.
- Petrochemical industries.
- Oil refineries.
- Vehicle water servicing centers etc.
Which motor is used in centrifugal pump?
The applications of different DC motors are: DC shunt motor: It is an almost constant speed motor. Hence it is used for driving constant speed line shafts, lathes, centrifugal pumps, small printing presses, paper making machines, etc.
Which pump used in ship?
This is a rotary displacement or a rotary positive displacement pump. There are two gears, one is driven by an electric motor through a chain or wheel drive. The other gear is known as the idle gear.
Is centrifugal pump Rotodynamic?
A: Rotodynamic pumps are kinetic machines in which energy is continuously imparted to the pumped fluid by means of a rotating impeller, propeller or rotor. To answer the question directly, a centrifugal pump is a type rotodynamic pump, and not all rotodynamic pumps are centrifugal pumps.
How does a reciprocating pump work?
The reciprocating pump works on the principle of positive displacement. A reciprocating piston pump consists of a piston that moves back and forth in a cylinder. The piston is connected with a crankshaft with the help of a connecting rod. This piston moves as the connecting rod move due to the motion of the crankshaft.
When reciprocating and centrifugal pump is used?
Difference between Centrifugal Pump and Reciprocating Pump:
| S. No. | Centrifugal pump |
|---|---|
| 4. | It is used for pumping high viscous fluid. |
| 5. | In this pumps discharge is inversely promotional to the viscosity of fluid. |
| 6. | Efficiency of these pumps are low compare to reciprocating pump. |
| 7. | Centrifugal pump have problem of priming. |
What are reciprocating pumps used for?
Reciprocating pumps are used in all injection based applications, such as: fuel injection in engines, medicine industry applications, and some water pumping applications.
What is the discharge pressure of a reciprocating pump?
Fig. 4.17. Schematic diagram illustrating a force of 10,000 pounds (44,482,216 N) acting on a piston with area of 50 in 2 (323 cm 2) yields a discharge pressure of 200 psi (1379 kPa). Reciprocating pumps, like reciprocating compressors, require inlet and outlet valves to ensure the liquid always travels from inlet to outlet.
What is suction pipe in reciprocating pump?
Suction pipe connects the source of liquid to the cylinder of the reciprocating pump. The liquid is suck by this pipe from the source to the cylinder. 2. Suction Valve Suction valve is non-return valve which means only one directional flow is possible in this type of valve.
What is the function of piston head in reciprocating pump?
The piston head is fitted with the piston rings for sealing. It helps to seal against the cylinder lining and minimize internal leakage. It is mandatory for the smooth operation of reciprocating pumps. The piston is moving backward and forward continuously in the cylinder.
