How Distributed Manufacturing is Evolving Business

Advantages of Distributed Manufacturing

Historically manufacturers own and operate a dedicated factory and develop or leverage existing supply chains to meet the needs of their customers. Consider a manufacturer located in Cincinnati, Ohio. They are in an ideal location for logistical distribution throughout the Midwestern and perhaps Southern United States. They have dozens of their own dedicated distributors and operate through other independent distributors. Traditionally this model has helped them to be a strong player in a large geographic footprint, yet they find it difficult to be competitive in the Northeast or Western U.S., and prohibited from being competitive internationally.

Brennan Opens Doors to New Global Headquarters Facility

Back in January of 2019, Brennan began the construction and remodel of our Corporate facility in Solon, OH. What was once a small, single facility back in 1953 is now one of many facilities across the globe.

Follow These Guidelines When Designing Your Hydraulic System

The design of hydraulic systems for heavy equipment and other machinery must take into account how and where the system is to be used.  In accordance with ISO 14121-1, a risk assessment must be conducted to ensure there are not any predictable risks in the design that could carry over into the field.  Reasonably foreseeable misuse shall not cause hazards.  If any portion of the design is unable to foresee potential risks in the field, then safeguards and warnings must be integrated into the system following safety standards as identified in ISO 12100.  As further precaution, ISO 13849-1 is used in the design of control systems.

Designing Hydraulic Fittings and Flanges into a System

Along with hose, tube and pipe conductors every hydraulic system incorporates a series of fittings, and often flanges, to connect the conductors to actuators, pumps, valves and other components. Because of the need for system maintenance, removable fittings are required, except for certain specialized systems.

Drain Lines, Valves, Filters, Lines and Pumps in a Hydraulic System

Sizing case drain lines. Typically, hydraulic motors and pumps have hoses that run to a case drain in order to drain excess internal oil from the motor.  Having a case drain usually requires running motors in series to avoid damage.  If the case drain line is undersized on a hydraulic pump (piston) it can cause the pressure in the case to be too high.  As the pump’s life depreciates its volumetric efficiency will decrease, which in turn will increase leakage from the case drain line.  If there is extreme case pressure it can cause the piston shoe to lift off the swash plate.  This will cause damage that will force the pump to stop working.  Go by the case drain port size or up-size it. It is important to make sure the case pressure is below the max rating, which if necessary, can be adjusted at the case drain port size, or increase the size of the port.  Case pressure can also become too high at:

A Quick Guide to Selecting Components for Your Hydraulic System

Selecting the correct inside diameter of fluid piping, such as steel tubing, steel pipes and hydraulic hoses

Piping should be sized to avoid drops in pressure. Unstable flow causes unnecessary friction between the walls of the piping and the fluid, ultimately creating lost energy in the system which will raise the temperature of the fluid.  This is due to excessive fluid velocity which causes turbulence and unplanned pressure drops.  By maintaining a practical fluid velocity, pump inlet conditions will be controlled which will reduce the potential of excessive heat.

Why the Design of A Hydraulic System Matters

Hydraulic systems in heavy equipment are designed utilizing certain principles for performing work using multiple components.  For instance, motors activate pumps; the pumps pressurize hydraulic fluid that passes through tubes to actuators.  As an example, the actuators in an excavator move the arm or bucket. The fluid passes through filters, is recycled through the system, and circulates back to the pump.

Considerations for Proper Hydraulic Component Selection

Proper Component Selection

Ensuring a leak-free hydraulic system begins with the design, which involves selection of the correct hydraulic fittings, hoses and other components for the application.  This could be a hose-end connection, hose or tube to port, a tube end or flange fitting.

Understanding Lockout & Tagout Safety Procedures

Lockout and Tagout Safety Procedures 

LOTO, or lockout and tagout, is the most relied upon procedure for maintenance safety.  According to OSHA, "Lockout/tagout refers to specific practices and procedures to safeguard employees from the unexpected energization or startup of machinery and equipment, or the release of hazardous energy during service or maintenance activities.

Brennan Moves Toward a More Environmentally Friendly Workspace

In January of 2019, Brennan broke ground on the new Global Headquarters facility in Solon, OH. Since then, much progress has been made and completion is nearing quickly. While many external and cosmetic changes have been made, there has also been internal change with a shift toward creating a more sustainable workspace.

The Importance of Being Proactive With Corrective Maintenance

Corrective Maintenance
System components should be inspected during preventative maintenance to address any anticipated issue before failure occurs.  Ideally the need for corrective maintenance can be identified and addressed during PM or in preparation for a scheduled or planned shutdown.  Be sure any repair of components is performed properly.  If not, issues may arise that can cause even greater harm.
