Types of Shanghai air compressors

Shanghai air compressors are mechanical devices used to generate compressed air. There are various types of air compressors that can perform different tasks and fit different industries.

• Reciprocating air compressor

  A Shanghai reciprocating air compressor uses pistons and cylinders to compress air. It's designed with a power source that moves the piston up and down. As the piston moves down, air fills up in the cylinder. When the piston moves up, the volume of air reduces, thus increasing the pressure of the air. The compressed air is dispensed through a pipeline. This type of air compressor is widely used in small workshops and industries because it’s affordable and the size is compact.

• Rotary air compressor

  Rotary air compressors work by using rotating screws or vanes to compress air. They operate continuously and can dispel large volumes of compressed air. A rotary air compressor is ideal for big commercial and industrial use that requires vast amount of pressure. This machine functions very well in manufacturing factories, construction sites and oil extraction industries.

• Centrifugal air compressor

  A centrifugal air compressor employs high-speed rotating impellers to increase the velocity of the air and convert the kinetic energy into compressed air. Centrifugal compressors are commonly used in large-scale industrial applications, pneumatic conveying systems, and cooling systems. Some of the key benefits of using a centrifugal compressor are: low maintenance cost, less space taken and very low noise level.

Specification & Maintenance

• Motor Power:

  The power of the motor is usually stated in kilowatts (kW) or horsepower (HP). It indicates the amount of power generated to drive the compressor.

• Working Pressure:

  The operating pressure of an air compressor specifies the maximum pressure it can reach. It is typically expressed in bar, psi (pounds per square inch), or kg/cm².

• Flow Rate:

  The amount of air a compressor can deliver is referred to as its flow rate. It is typically expressed in cubic feet per minute (CFM) or liters per minute (L/min).

• Displacement:

  The volume of compressed air generated by a compressor is referred to as its displacement. Like the flow rate, it is usually measured in CFM or L/min.

• Tank Size:

  A compressed air storage tank's dimensions affect how much compressed air it can hold. Generally, tanks are available in sizes from small (typically a few gallons/liters) to large (up to thousands of gallons/liters).

• Power Source:

  The type of power source that powers a compressor is referred to as its power source. It can be an electric motor, a gas engine, or a diesel engine, among others.

• Regular Inspection and Maintenance:

  Conduct regular inspections of the air compressor to promptly discover potential issues. Check the connections, fasteners, and seals to ensure there is no air leakage. Regularly calibrate and test the pressure and flow to ensure that the compressor is operating at the correct parameters.

• Replace Filters:

  The air intake of the air compressor goes through the filter, which prevents impurities from entering. Regularly replacing filters can ensure that the compressor is supplied with clean air. Set a filter replacement schedule based on the usage environment and filter quality.

• Oil Change:

  If the air compressor is oil-lubricated, it is necessary to change the oil regularly. The compressor's lubricating oil lowers friction and dissipates heat. Proper oil changes can maintain the smooth operation of bearings and the cooling of the machine.

• Maintenance of Cooling System:

  Air compressors need to maintain proper operating temperatures. Regularly check the cooling system, such as cooling fans and radiators, to ensure efficient heat dissipation. Also, check the coolant level and add coolant in time if necessary.

• Regular Cleaning:

  Cleaning the air compressor helps remove dust and dirt that accumulate over time. Wipe the surfaces and components of the compressor with a soft cloth and clean the intake and exhaust ports. Ensure proper ventilation around the machine to avoid overheating.

Uses and scenarios of Shanghai air compressors

Industrial air compressors create high-pressure air to power machines in many manufacturing plants. Some of the common applications of air compressors in factories include the following:

• Pneumatic tools: Air compressors are primarily used to power pneumatic tools such as nail guns, impact wrenches, sanders, drills, spray guns, and many more. Pneumatic tools are common in many factories due to their lightweight, higher power-to-weight ratio, reliability, and greater efficiency than electric tools.
• Mechanical presses: Air compressors power the high-pressure air used in mechanical presses to bend, compress, and shape various materials. Mechanical presses are prevalent in the automotive industry.
• Inflation: Air compressors are also used in factories to inflate tires, sporting goods, air mattresses, and balloons, among other items.
• Packaging: Factory air compressors are used to package products by creating high-pressure blasts of air to seal products in containers and remove excess product from sealed containers. Air compressors are also used for bottle and canister inflation.
• Conveying: Air compressors are used to convey light materials such as powders and grains by creating high-pressure air blasts used to transport the materials through pipelines.
• Cutting and grinding: Air compressors power cutting and grinding machines in factories that cut metals and other materials using high-pressure air streams.
• Strapping and fastening: An air compressor can be used to fasten products together by creating a high-pressure blast of air that drives straps and nails into a material.
• Paint spraying: Air compressors are used in spray guns to paint products. They can also be used to de-spray or unpaint products before manually painting them.
• Cleaning: Air compressors can be used in cleaning applications to remove foreign materials or excess liquids from the surface of an object. They create a high-pressure air blast used to remove foreign objects from the surface.

How to Choose Shanghai Air Compressors

The first step to buying a suitable air compressor for sale is to identify the target customers' needs. A variety of factors can indicate the customers' needs that a business buyer should consider when researching the air compressor's application. They include the type of tools and equipment customers use, the required PSI and CFM, the preferred power source, workstation size, and noise level.

As mentioned earlier, different types of air compressors produce varying amounts of pressure and volume. A business buyer should familiarize themselves with the PSI and CFM of each air compressor type and the tools that use them. For example, the portable air compressor is suitable for small jobs like inflating tires and operating small hand tools. It works perfectly for a workstation that runs on pneumatic tools like nail guns. However, it may not produce enough CFM to power a paint sprayer. A gas-powered or oil-lubricated air compressor for sale will be better at handling that job.

Consider the air compressor's preferred power source. Electric air compressors are ideal for indoor use, while gas-powered air compressors are suitable for outdoor use. Workstation size can also affect the choice of air compressor. Determining the setup can help one find a compact or portable air compressor that will not take much space. Some customers may prioritize a quiet air compressor, while others will look for the fastest one to get the job done. Finding the ideal choice for each customer application will give one a competitive advantage when reselling.

Shanghai air compressor Q&A

Q1: Who makes Shanghai air compressor?

A1: Shanghai Screw Compressor has two parent companies: Shanghai Electric Group Corporation, which provides industrial products and services, and Shanghai Tongli Compressor Co., Ltd., which specifically focuses on air-compressor technology.

Q2: How long will a Shanghai air compressor last?

A2: A well-maintained air compressor can serve between 10 to 15 years or even longer before it starts to demand frequent repairs and becomes economically unwise to maintain.

Q3: What is the maintenance schedule for an air compressor?
