Difference Between Pump and Compressor

Pumps have the ability to move liquids or gases. Compressors typically only move gas due to its natural ability to be compressed. Pumps and compressors both have very high pressure rises. There are different types of compressors that move air into a chamber.

What is the difference between centrifugal pump and compressor?

Centrifugal pump

The key difference between such compressors and pumps is that the compressor working fluid is a gas (compressible) and the pump working fluid is liquid (incompressible). Again, the engineering methods used to design a centrifugal pump are the same as those to design a centrifugal compressor.

What is the difference between pump and motor?

The main function of motor is to change the energy from electrical to mechanical. A pump operates with a motor otherwise an engine. The motor operates with an energy source. A pump moves liquid with the help of forces such as air.

Is a vacuum pump a compressor?

A vacuum pump is just an air pump, like a compressor, where you use the input side for suction, rather than using the output side for blowing. Many air compressors make good vacuum pumps if you can find the air intake, enclose it, and attach an appropriate hose or fitting.

What is a compressor used for?

Air compressors have many uses, including: supplying high-pressure clean air to fill gas cylinders, supplying moderate-pressure clean air to a submerged surface supplied diver, supplying moderate-pressure clean air for driving some office and school building pneumatic HVAC control system valves, supplying a large ...

What are the three types of compressors?

The three most common air compressors are the reciprocating, rotary screw and centrifugal. Reciprocating air compressors are considered positive displacement machines, which means they increase the pressure of the air by reducing its volume.

What is the principle of compressor?

Air compressors work by forcing air into a container and pressurizing it. Then, the air is forced through an opening in the tank, where pressure builds up. Think of it like an open balloon: the compressed air can be used as energy as it's released.

What are the types of pumps?

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.

Which motor is used in pumps?

The motor used to drive the pump is typically a three phase, squirrel cage induction motor, with a nameplate power rating in the range 7.5 kW to 560 kW (at 60 Hz).

Does a pump need a motor?

Pumps are generally powered by electric motors that drive an impeller. As a result of movement of water, a partial vacuum is created which is later filled with more air. A motor, on the other hand, is based on Faraday's law of electromagnetic induction which is one of the most basic laws of electromagnetism.

Can compressor oil be used in a vacuum pump?

Vacuum pump oil is used in mechanical vacuum pump of vacuum system. Compressor oil is mainly used in the lubrication of cylinder and piston friction parts of gas compressor, exhauster and piston pump, as well as inlet and outlet valves. ... Low viscosity oil is also used in each Type rotary compressor.

What can a vacuum pump be used for?

Vacuum pumps are also used for decorative vacuum coatings on metal, glass and plastics, energy saving and durability of glass, ophthalmic coating, hard coatings for Formula One engine components, dairy equipment such as milking machines, vacuum impregnation of electric motor windings or wood, trash compactors, air ...

How does a vacuum pump works?

The vacuum pump functions by removing the molecules of air and other gases from the vacuum chamber (or from the outlet side of a higher vacuum pump if connected in series). While the pressure in the chamber is reduced, removing additional molecules becomes exponentially harder to remove.
