Engineering Tools for Pneumatics

air consumption calculator

The air consumption calculator is an option for monitoring energy efficiency, already in the design phase.

Rexroth facilitates the work of design engineers with a number of consistent, easy-to-operate online tools

  • Catalog
  • Configurators
  • CAD
  • Calculation programs with air consumption calculator
  • Circuit diagram software
  • eShop, including queries for delivery times and prices

From the digital catalog to the shopping basket: many machine industry suppliers provide options to obtain information or place orders with the click of a mouse. Rexroth’s integrated online options go one step further: pneumatic components can be efficiently designed, configured, downloaded as 3-D CAD data, and ordered on-the-spot – from product selection to documentation of the finished product and ordering in no time flat.

Simple, intuitive operation is a high priority for Rexroth’s online tools for pneumatic components. You can get results in just a few mouse clicks, and the results here are more than just a data sheet. Less than 30 minutes are all that it takes to go from a design idea to a completed order – including the material number, price, delivery time, technical documentation, and CAD files. Almost the entire product range can be configured using these tools, which are interlinked to allow easy, useful switching, for example from the configurator to the eShop.

The customer no longer needs to go through time-consuming manual calculations; the dimensions and component combinations can be checked for plausibility and an energy- and cost-efficient selection can be made.

The online catalog at serves as the primary reference and contains all technical information on a product. From the catalog, the user can invoke the other tools with a single mouse click.

The configurators permit the optimum selection of suitable components; multi-level configurations are possible. The selection of accessories is also integrated in this step. Program rules ensure that only correct combinations can be selected. The system generates a unique material number for the configured product. This makes it possible to order completely new product variants using a regular, specifically generated material number. As the result of the configuration, the user receives detailed documentation: in the area of system design this comprises the circuit diagram, dimensioned drawing, item-based drawing, and CAD data. Administrative data include the material number for the order, the price, and delivery time, as well as a parts list.

The generated 2-D or 3-D CAD data can be downloaded and integrated in design drawings.

Starting from Acrobat Reader version 8.0, the customer can manipulate 3-D CAD drawings in space, thus allowing a direct, dynamic view of the configured product from all sides. An additional special feature: in addition to finished components, newly configured products including accessories are also available for download as CAD files.

With its calculation programs, Rexroth provides a tool in which the parameters of an application can be specified. The programs calculate the suitable product for the application; the product can then be viewed in the catalog, configured as necessary, and ordered.

For energy-efficient applications, the air consumption calculator determines the required air quantity. With operating data for compressor power, operating hours, mass to be moved, stroke and cycle time, the calculator generates the energy requirements for different configurations. The design engineer can immediately recognize the effects that different cylinder diameters and valves, as well as tubing lengths and diameters, will have on air consumption and then create the most energy-efficient combination.

The free-of-charge circuit diagram software, D&C Scheme Editor 2.0, provides an additional service. This intuitive software enables the standard-compliant creation of even complex pneumatic circuit diagrams. The user has access to an extensive pneumatics library containing symbols that can be selected as needed and entered into the worksheet by “drag and drop”. The circuit plan can be supplemented by data sheets and hyperlinks – all in a single application. Knowledge of CAD is not necessary to use the Scheme Editor. The software generates parts lists based on the material and item numbers of the components.

The eShop functions as the customer’s shopping basket. The customer places an online order using a Rexroth material number and can then query for prices and delivery times.
