Test Bench
The Hydmark’s hydraulic test bench is the ultimate diagnostic tool, capable of thoroughly testing a vast array of new or rebuilt components and sub-assemblies prior to their installation in a working system. The Hydmark’s hydraulic test can test the efficiency of hydraulic pumps and motors as well as valves and cylinders.
Our test benches are designed for general shop testing of hydraulic pumps, valves, motors, and cylinders as individual components. Utilization of a test bench enables the operator to conveniently simulate a component’s function in its circuit and perform a realistic test, thereby providing the necessary quality control before any repaired component is replaced on a machine. Component performance is determined by comparing test results of the component loaded with a manufacturer’s specifications to an unloaded condition.
Pumps and motors can be tested dynamically. Pump and motor testing is aided by the wide speed and torque ranges built into the bench and by the universal mounting bracket and mounting accessories that come with the bench. An open loop hydrostatic variable volume hydraulic system provides the power and speed control for the drive shaft. Motors can be dynamically tested, under load, for operating efficiency. Pumps can be tested for external leakage and volumetric efficiency in either direction, at speeds from 100 to 2400 rpm. The test bench can also be used to break-in pumps and motors to manufacturer’s specifications before they are installed in a system.
Cylinder leaks are easy to find. Double-acting cylinders may be cycled, and tested for both internal and external leakage at any point of piston travel. Scored cylinder walls and defective packing are easily detected. Single-acting cylinders are tested at maximum stroke.
Valve testing time is minimized. Pressures can be set, external and internal leakage spotted, flow and pressure data can be generated and checked against operating requirements and overall valve efficiency determined. Optional electrical and pilot pressure supplies are available on the bench for testing solenoid-actuated and pilot-operated valves.
What the Test Bench can do for you:
Test incoming hydraulic components to identify problems
Test all rebuilt parts for proper operation to ensure customer satisfaction.
Carefully “break in” components with rotating parts (pumps and motors) using clean, filtered hydraulic fluid to give rebuilt pumps and motors a long service life.
Prevent warranty claims and help customers solve hydraulic system problems.
Test used hydraulic components before they are sent out, preventing unnecessary expensive repair work. In many instances, you may find that only an inexpensive shaft seal or housing o-ring is necessary to put a component back in operation.
Ensure you are receiving quality rebuild work and prevent expensive additional production equipment downtime by performance testing repaired components.
Conduct performance tests on rebuilt hydraulic components for proper operation before they are reinstalled on your production hydraulic equipment, preventing additional expensive production equipment downtime.
Check used components removed from production equipment. Parts can be tested for proper operation and unnecessary repair work can be eliminated.
