The HLP series servo-controlled pressure gauge fatigue test bench utilizes reciprocating pulse pressurization technology—driven by a booster cylinder and using a liquid test medium (such as water or hydraulic oil)—to simulate a liquid pressure pulse environment. It is primarily designed for conducting pressure-cycling fatigue tests on various types of gauges to evaluate their fatigue life and modes of fatigue failure. Key features include precise pressure control, high testing frequency, low power consumption, minimal heat generation, and low noise levels.
