Difference Between Pump and Compressor


The pump and compressor is a mechanical component. In this article we will study differences between Pump and Compressor  in detail.

Before moving to our main topic we will see definition of these two first,

What is a Pump?

  • A Pump is a device used for transferring the liquid to another place from one place.
  • For example In Hydro Plant the water from the head pond to the turbine blade, Pump is used for moving the fluid.
  • The pump is basically used in hydraulic machines to lift the water from the ground surface to the topmost position.

There are two types of Pump:

  1. Positive Displacement Pump and
  2. Dynamic Pump

What is Compressor?

  • Compressor is also a mechanical component in which the compressed gases are stored and supply when needed.
  • From Compressor we supply compressed gases to vehicles like motorcycle, 4 wheeler and so on.

Different types of Compressor are:

  1. Axial Compressor.
  2. Centrifugal Compressor.
  3. Rotary Screw Compressor.
  4. Reciprocating Air Compressor.

Difference between Pump and Compressor:

PUMPCOMPRESSOR
Pump is a mechanical device which is used for transferring the liquid and gases from one place to another place.Compressor is also a mechanical device used for storing the compressed gases and releases whenever needed.
The pressure of energy increases at higher heights.But there the pressure of energy increases by compressing gases.
In Pump, there is no change in the volume at the inlet to outlet.But here In Compressor, there is a change in the volume at the inlet to outlet.
A pump is used for transferring liquid like water, oil, and so on.But the compressor is used for transferring only gases.
There is not having storage here. Pump only transfers.The compressor has storage and it stores the Compressed gases.
A pump is used to increase the pressure of the incompressible fluid.A Compressor is used to increase the pressure of the compressible fluid.
When it comes to the price, the pump price is less.But the compressor price is more comparatively Pump.
The pump is used in domestic places like Home, Machine, Lifting water, and so on.Whereas the compressor also work at domestic place only like supplying the compressed air into Motorcycle wheel, Bicycle wheel and othrs.
A pump is governed by the suction head and Delivery head.A compressor is governed a compression ratio, The compressor ratio is output pressure to input pressure.
In Pump the kinetic energy increases of the fluid which further increases the pressure energy.But in compressor by pressuring in smaller volume it Increases the potential energy.
There is no such compression ratio here.The compression ratio is always more than one.

Laser Cutting Machine

Laser cutting     is a fabrication process which employs a focused, high-powered   laser beam   to cut material into custom shapes and designs. This process is suitable for a wide range of materials, including metal, plastic, wood, gemstone, glass, and paper, and can produce precise, intricate, and complex parts without the need for custom-designed tooling. There are several different types of laser cutting available, including fusion cutting, oxidation cutting, and scribing. Each laser cutting process can produce parts with precision, accuracy, and high-quality edge finishes, and with generally less material contamination, physical damage, and waste than with other conventional cutting processes, such as mechanical cutting and waterjet cutting. However, while laser cutting demonstrates certain advantages over more conventional cutting processes, some manufacturing applications can be problematic, such as cutting reflective material or material requiring secondary ma...

Biomechanical engineering

Image
 Biomechanical engineering is a field that integrates principles of mechanical engineering with biological systems, particularly focusing on the interaction between mechanical factors and living organisms. Here are some key aspects and applications of biomechanical engineering: Biomechanics : This involves the study of the mechanical aspects of biological systems, such as how forces affect cells, tissues, and organs. Biomechanical engineers apply principles from mechanics (statics, dynamics, fluid mechanics, etc.) to understand and analyze biological structures and functions. Medical Devices : Biomechanical engineers design and develop medical devices such as prosthetics, implants, orthotics, and assistive devices. These devices aim to improve mobility, enhance bodily functions, or replace damaged biological structures. Tissue Engineering : This field combines engineering principles with biology to create biological substitutes that restore, maintain, or improve tissue function. Bi...

Coordinate Measuring Machine Probes

Image
  A  Coordinate Measuring Machine  is defined by the ability of its probe. As with CMMs, there are several types of probes available. There is the contact probe, which measures the workpieces by making contact with them. The non-contact probe that employs lasers or machine vision probes which scan with optical sensors. Contact probes are a more accurate way of measuring. However, the laser or machine vision probes are far quicker to use, while still holding a high degree of accuracy. There are also multi-sensor probes which combine both touch and optical scanning, giving the benefit of both types in one probe. Coordinate Measuring Machines: Contact Probes The two most common contact probes are Touch Trigger Probes and Analog Scanning Probes. Touch Trigger Probes: A touch trigger probe has a stylus that is attached to a bearing plate. This is then connected to pressure sensors inside the housing of the probe. Each time the probe makes contact with the workpiece, it generat...
