Which one is the part of reciprocating pump?
MAIN COMPONENTS OF THE RECIPROCATING PUMP- • Cylinder with a piston, piston rod, connecting rod, crank.
Delivery pipe • Suction, delivery valve.
On the basis of water being in contact with one side or both sides of the piston..
Why it is called centrifugal pump?
A centrifugal pump is a mechanical device designed to move a fluid by means of the transfer of rotational energy from one or more driven rotors, called impellers. … The action of the impeller increases the fluid’s velocity and pressure and also directs it towards the pump outlet.
Which pump is more efficient?
In general, a reciprocating pump is more efficient than a centrifugal pump. Reciprocating machines are generally applied on low-flow/high-head service. Centrifugal pumps can have efficiencies as low as 40 percent on low-flow/high-head service.
What is negative slip in reciprocating pump?
Slip is defined as the difference between theoretical discharge and actual. discharge. If actual discharge is greater than theoretical discharge negative value is found this negative value is called negative slip.
Which pump is used for high discharge?
Please see the following image where there is comparison between positive displacement pumps (Reciprocating pumps are type of PDP) and Dynamic pumps (Centrifugal pumps). It is clear that PDP are used when we need high outlet pressure and dynamic pumps are used when we need high discharge.
What are the types of reciprocating pump?
In brief: There are four common types of reciprocating pumps – power pumps, power diaphragm pumps, air-operated pumps and air-operated piston pumps. Power pumps convert a rotary motion into reciprocating motion that can develop more than 40,000 psi discharge pressure or deliver more than 4,000 gpm.
What is the function of reciprocating pump?
It is often used where a relatively small quantity of liquid is to be handled and where delivery pressure is quite large. In reciprocating pumps, the chamber that traps the liquid is a stationary cylinder that contains a piston or plunger.
What is the major drawback of reciprocating pump?
Disadvantages of Reciprocating Pump: This reciprocating pum has high wear and tear therefore requiring very high maintenance. The flow is not uniform, so we have to fit a bottle at both ends. The flow is very low and cannot be used for high flow operation.
What is pump and its types?
Pumps can be classified by their method of displacement into positive-displacement pumps, impulse pumps, velocity pumps, gravity pumps, steam pumps and valveless pumps. There are three basic types of pumps: positive-displacement, centrifugal and axial-flow pumps.
What is the application of centrifugal pump?
Applications of Centrifugal Pumps: Supplying water, boosting pressure, pumping water for domestic requirements, assisting fire protection systems, hot water circulation, sewage drainage and regulating boiler water are among the most common applications.
What is the difference between reciprocating pump and centrifugal pump?
Centrifugal pump is a rotary pump uses the kinetic energy of impeller to transfer liquid. A reciprocating pump is a positive displacement type pump which is forced through the piston.
What are the two types of piston pump?
The two main types of piston pump are the lift pump and the force pump. Both types may be operated either by hand or by an engine.
