Capabilities
Learn why SAI Hydraulic Motors has been the icon of "power through efficiency" for the past 50 years. Although this story began over 50 years ago, the reason SAI has remained one of the leading companies in the design and production-technology of crankshaft radial piston hydraulic motors has been their advancements in technology year after year. They have specialized in the ability to transform hydraulic power into mechanical power and help designers match overall efficiencies to the application requirements they are seeking. Let's break it down

Hydraulic System Efficiency
This requires hydraulic system designer to first match the motor, then the pump to a specific system performance expectation. Whether the requirement is to do something within a specific time frame, or in handling a given amount of load, the design of the entire system will change depending on the motor selected.
That  is why the motor selection comes first in the process; you start with the load requirement, then work back to the prime mover—the pump that will put the fluid power into the motor selected to deliver the performance goal.

Motor Type
Each motor type— gear, vane, in-line piston, bent-axis piston and radial piston—has a specific performance profile. So, knowing the application performance requirement and which motor type best meets the objective is the first step. Then it’s necessary to evaluate the design advantages of your motor options along with the degree of complexity you want for the overall system. In the end, it all goes back to the application’s performance expectations.

Motor Function
A hydraulic motor is a hydraulic actuator that, when properly connected into a hydraulic system, will produce a rotary actuation. This can be unidirectional or bidirectional depending on the system design. Motors are similar in design to pumps only where a pump takes a rotary actuation to move hydraulic fluid out of the unit, whereas a motor will take flow into itself and put out a rotary actuation.

Motor Selection Criteria

  1. The application of the hydraulic motor generally dictates the required horsepower and motor speed range, although the actual speed and torque required may sometimes be varied while maintaining the required horsepower.

  2. The type of motor selected depends on the required reliability, life, and performance. But where output speed must be reduced, the overall cost of the motor with speed reduction must be considered to optimize the overall drive installation costs.

  3. Once the type of the fluid is determined, the selection of actual size is based on the expected life and the economics of the overall installation of the machine.
    Caution: A fluid motor operating at less than rated capacity will provide a service life extension more than proportional to the reduction in operation below the rated capacity.

  4. Once the type of fluid is determined, the selection of actual size is based on the expected life and economics of the overall installation on the machine.
    Caution: A fluid motor operating at less than rated capacity will provide a service life extension more than proportional to the reduction in operation below rated capacity.


 SAI Hydraulic Motor Product Features

FEATURE: High Starting Torque
BENEFIT: The SAI motor has virtually the same starting torque and dynamic torque. This is due to the presence of the crankshaft roller bearing. With this, startup friction is greatly reduced.

FEATURE: High Volumetric Efficiency
BENEFIT: In all SAI motor parts under pressure, the sealing is provided by Teflon/elastomer seals. The seal can compensate for the normal wearing of parts, as well as the natural expansion of the parts under stress. This enables SAI motors to maintain excellent volumetric efficiency, even after several thousand working hours. This is especially useful in applications requiring precise speed control at very low speeds or good braking capability.

FEATURE: Contamination Resistance
BENEFIT: The SAI design can withstand very large contamination particles in the system, up to 40 µm. All dynamic parts, such as cylinders, pistons, distributors, and valves, are hardened to further enhance their performance and contamination resistance. Large clearances and seals between dynamic parts also adds to the contamination resistance.

FEATURE: Thermal Shock Resistance
BENEFIT: The large clearances also allow SAI motors to have excellent thermal shock resistance. The large clearances will accept thermal expansion, and will not cause the dynamic parts to come in contact with each other and prolong the life of the motor.

FEATURE: Cavitation Resistance
BENEFIT: The innovative SAI design allows the motor to run in partial or full cavitation. The roller bearing under the piston does not require lubrication, and the piston retaining rings ensure that the pistons remain in firm contact with the central roller bearing. These innovative features allow the SAI motor to operate in full cavitation. The traditional hydraulic motor design with hydrostatic balancing under the pistons require lubrication at all times. If there is no lubrication present, it will experience significant frictional damage.

EHA Electro-Hydraulic Automation

EHA has the capability and the resources to refurbish valuable but outdated equipment with updated automation controls and safety devices.

Project: Refurbish customer’s numerous industrial press machines to achieve increased productivity, better mechanical performance and safety.

Goals:

  1. To cost-effectively refurbish several pieces of similar equipmentHuman Interface technology on Industrial Press
  2. Keep components similar and interchangeable
  3. Decrease spare parts inventory
  4. Improve machine automation architecture
  5. Install equipment and verify with test pieces

Increased Productivity

A human-machine interface (HMI) is typically local to one machine or piece of equipment, and is the interface method between the human and the equipment/machine. An operator interface is the interface method by which multiple equipment that are linked by a host control system is accessed or controlled.

Each press was updated with a HMI (Human Machine Interface) which stores a recipe of data for each die change. Each die has a part number punched into the HMI and parameters are loaded specific to that die to control the position and tonnage for each part. Waste is virtually eliminated and setup time was greatly reduced to minimize change-over labor cost.

  • The press has the capability to pass on information for recording cycle times and number of cycles over Ethernet network.

Better Mechanical Performance

The existing hydraulic system was loud and inaccurate requiring the use of multiple directional control valves, flow controls, and manually adjusted limits for positioning. In addition:

  • The set-up procedure was labor intensive
  • Had lots of part variance
  • Created wasteful man-hour costs
  • Was full of system shock and leaked

The old system was eliminated and simplified with one proportional valve for motion control, a pressure transducer for tonnage control, and a linear transducer for position control. The new, simplified combination has increased speed, accuracy, force, position control, and is quieter.  Additional cooling and filtering were added for heat and contamination control for less down time.

Safety

The old system was associated with operational safety hazards. Improvements included:

  • Guarding & light curtains
  • Safety switches
  • Safety controllers
  • Hydraulic lock valves (to reduce the possibility of an unsafe condition during operation.

The guarding was installed to provide safety for operator and non-operators by incorporating physical barriers around the press using doors for accessibility with locking safety switches.  An area scanner was added to simplify accessibility during production for the operator eliminating opening and closing safety guarding creating operator fatigue.  The cycle start was done with a no-touch, two hand no tie down optical switches to help contribution to safety and help eliminate operator fatigue.

Freeedom Foundation

Tasked with a challenge, employees at Iowa Fluid Power know the meaning of success. The Veterans' Freedom Foundation provides financial assistance and other services to veterans.  It might just mean a cab ride to the hospital or sending a care package, but we feel fortunate to help provide any assistance needed to our veterans. Veterans’ Freedom Foundation bridges this gap.  If veterans face losing their homes or vehicles due to a missed payment, Veterans’ Freedom Foundation donates money to make the payment, buying time until full assistance arrives.

Our recent challenge at IFP was to collect donations to exceed our goal of buying and distributing 2200 lbs. of food. We did just that this week with over a ton of food going to this important charity.

Food donation to the Veteran's Freedom Foundation

Testimonials:
Without the Freedom Foundation I and my wife and child would be homeless. This is the second time they have been a tremendous help with funds, food,  and support. This foundation has plenty of resources to call upon. The people here have giant hearts and have the Vets interest in mind!!         
Thank you!
J.K.

Freedom Foundation,
I would like to thank you from the bottom of my heart for your assistance. From time to time there are Veterans like myself that fall short. I'm grateful that Veterans help Veterans. We look out for each other.
Richard M

In observance of Veteran's Day, the Veteran's working at the IFP corporate office will be distributing the food to those in need. To learn more about the Veteran's Freedom Foundation, visit:
