Selecting a hydraulic power supply for vibration test systems starts with your required operating pressure and flow, or the test profiles you need to run.
Compatibility with your shaker and the available facility utilities are also important when comparing quotes.
Application Requirements and Test Profiles
For an existing vibration test system, start with the equipment’s specified pressure and flow needs. If you’re planning a new installation, share your intended test profiles with Team Corporation so it can evaluate the hydraulic supply requirements for the proposed equipment.
Load, stroke, and speed are relevant to shaker performance, but customers can provide equipment specifications or intended profiles as the starting point for power supply selection. Team Corporation sizes its hydraulic power supplies to accommodate its servovalves and also offers units for integration with components from other manufacturers.
Optimal Working Pressure
Your power supply must maintain the operating pressure required by the vibration test equipment. Confirm that requirement with the equipment supplier, then review the proposed hydraulic circuit for pressure losses.
Team Corporation accounts for pressure drops when sizing the supply so the test equipment receives its required operating pressure. Share your proposed hose routing and connection arrangement during selection so the company can evaluate losses across the circuit.
Flow Rate Requirements for Your Test Profiles
Your existing test equipment’s flow specification gives you a basis for comparing hydraulic power supplies. A pump’s volumetric flow rate measures the liquid volume it delivers per unit of time. Share the required capacity in gallons per minute or liters per minute when requesting a quote.
For a new shaker, Team Corporation can assess the supply requirements based on the test profiles you intend to run. Its HPS-65 and HPS-110 models offer flow capacities of 15 and 30 gallons per minute, respectively. Compare the proposed unit’s flow capacity against your requirements to confirm its suitability for your application.
Electrical Power and Installation Requirements
Before ordering, compare the proposed unit’s electrical requirements with the supply available in your facility. Team Corporation lists voltage, frequency and phase specifications by model, so confirm the configuration for your installation with its representative before proceeding.
Equipment dimensions also affect placement. Review the proposed unit’s length and width against your available floor space, then check its height and access needs before finalizing the layout.
Where personnel work near the power supply, discuss sound requirements during selection. Team Corporation offers an optional quiet motor and pump assembly on many models. Ask which configurations support that option and request the sound information you need to evaluate placement.
Hydraulic Oil Needs and Reservoir Capacity
Team Corporation recommends Mobil DTE 26 for its hydraulic test systems. Any alternative fluid requires the company’s approval.
The minimum oil cleanliness level is ISO 4406:16/14/11, with ISO 4406:15/13/10 as the preferred level. Liquid viscosity decreases as temperature rises, which reduces resistance to flow. For this equipment, the hydraulic fluid supplied during operation should remain between 100 and 115°F.
Water content should remain at or below 100 parts per million, particularly where equipment is exposed to humidity or condensation. Recommended maintenance includes oil analysis and filter servicing every 500 operating hours or every three months, whichever comes first.
Reservoir capacity depends on the installation’s hose lengths and sizes, as well as its pressure and flow requirements. These details inform reservoir selection for the proposed test setup.
Cooling, Filtration and Operating Controls
The installation’s valves, actuators, and bearings determine its oil conditioning requirements. Recommended filtration uses an absolute rating of 3 microns for the pilot and main lines, and 10 microns for the return line. Filter designs that prevent bypass help ensure oil passes through filtration.
Cooling capacity must accommodate the heat generated at full load. Facility planning should account for the selected unit’s heat removal needs and cooling water requirements. Models with heat exchangers include water-saving valves, while the HPS-6A uses air cooling.
Noise-control options can also affect the final configuration, so ask whether the proposed unit supports acoustic enclosures, vibration isolation, or an optional quiet motor and pump assembly if your lab has sound limits or nearby workstations.
Remote start and stop capability and interlocks for power interruptions also factor into control integration. Monitoring sensors track oil temperature, oil level, pressure, and filter condition. Confirm these functions and their connections against your test system’s control requirements before installation.
Supplier Expertise and System Integration
Compare supplier quotes against the same pressure and flow requirements, then check compatibility with your existing test equipment. Each quote should identify the proposed configuration and clarify which installation provisions your lab must supply.
Team Corporation makes hydraulic power supplies for use with its own components and equipment, as well as equipment from other manufacturers. Available features include remote start and stop capability and monitoring sensors for oil temperature, oil level, pressure, and filter condition.
Electrical requirements and cooling arrangements vary by model, so include these details in your comparison. Review equipment dimensions against the available installation space and confirm whether the quoted configuration includes any optional quiet motor and pump assembly.
Frequently Asked Questions
Equipment specifications give you a good starting point for a discussion with a supplier. Your installation layout and available utilities help complete the selection.
How do you match a power supply to a specific test system?
Match the supply to the pressure and flow requirements of your existing or planned equipment. If you have test profiles instead, they can serve as the basis for assessing the required hydraulic capacity.
What is the ideal reservoir size for continuous testing?
Reservoir capacity depends on the installation’s hose lengths and sizes, as well as its pressure and flow requirements. These details guide the selection of the tank for the proposed test setup.
How do environmental factors affect fluid power?
Your facility must accommodate the selected unit’s heat removal and cooling utility requirements. Sound levels may also influence equipment placement or the selection of an optional quiet motor and pump assembly.
How does fluid media impact power transmission?
Mobil DTE 26 is the recommended fluid for these hydraulic test systems, and alternatives require equipment supplier approval. Oil cleanliness and an operating fluid temperature of 100 to 115°F also form part of the specified operating requirements.
How do you balance price and quality when buying?
Look beyond the initial quote to evaluate reliability, track records, and available technical support. Equipment that works well with your current test system prevents expensive compatibility problems that can offset any up-front savings.
Secure the Best Power Supply for Your Lab
Before accepting a quote, confirm that it addresses the pressure and flow your tests require and the utilities your facility can provide. Share your equipment specifications or intended profiles, along with the proposed hose layout, so the selection reflects your intended outcome.
