Site Dumper and uses

Site Dumper
A dumper is a vehicle designed for carrying bulk material, often on building sites. Dumpers are distinguished from dump trucks by configuration: a dumper is usually an open 4-wheeled vehicle with the load skip in front of the driver, while a dump truck has its cab in front of the load. The skip can tip to dump the load; this is where the name "dumper" comes from.

Air Compressor and it uses

Air Compressor
An air compressor is a device that converts power (using an electric motor, diesel or gasoline engine, etc.) into potential energy stored in pressurized air (i.e., compressed air). By one of several methods, an air compressor forces more and more air into a storage tank, increasing the pressure. When tank pressure reaches, its engineered upper limit the air compressor shuts off.

Classification

Compressors can be classified according to the pressure delivered:

  1. Low-pressure air compressors (LPACs), which have a discharge pressure of 150 psi or less
  2. Medium-pressure compressors which have a discharge pressure of 151 psi to 1,000 psi
  3. High-pressure air compressors (HPACs), which have a discharge pressure above 1,000 psi

They can also be classified according to the design and principle of operation:

  1. Single-Stage Reciprocating Compressor
  2. Two-Stage Reciprocating Compressor
  3. Compound Compressor
  4. Rotary-screw compressor
