Most industrial machinery dealing with fluids experience cyclic pressure load from time to time. Unlike the steady-state load, cyclic load can cause more severe malfunctions or damage and eventually shortens service life of the machines.

High-pressure impulse profile

Test Stands for Impulse Testing

Southwest Research Institute (SwRI) staff have developed three dedicated test stands to perform impulse tests to help component and machinery manufacturers to evaluate the cyclic load environment. These impulse test stands cover a very wide range of pressures such as:

Low Pressure Range: 0–300 psi
Medium Pressure Range: 0–4,000 psi
High Pressure Range: 0–30,000 psi

Low-pressure impulse profile

Test stands are carefully developed and can be used to conduct impulse tests in accordance with ISO, SAE, and military specifications. They can also be used to conduct nonstandard or industrial-specific impulse tests to evaluate components such as:

Fuel hoses
Oil hoses
Seals
Fuel rails and injectors
Pressure sensors
Fuel filters
Oil filters
