Study on the Influencing Factors of the Response Characteristics of the Slide Valve-Type Direct-Acting Relief Valve with External Orifice

The slide valve-type direct-acting relief valve with external orifice (SVTDARVWEO) is widely used in hydraulic systems, and its response characteristics are influenced by key factors. It of great significance to carry out research on the influencing factors SVTDARVWEO. working principle SVTDARVWEO analyzed present study. simulation model established using AMESim. influence diameter, viscosity coefficient, element mass, spring stiffness, oil seal length, diameter studied. results show that: (1) smaller is, oscillation frequency, amplitude maximum overshoot pressure, flowrate, displacement velocity are. (2) When coefficient 50 N/(m/s), 55 N/(m/s) 60 oscillate periodically, but decreases gradually, frequency 250 Hz. will reach their respective stable values earlier. (3) mass 0.01 kg, 0.015 kg 0.02 gradually. value (4) stiffness greater higher number oscillations are, addition more time being required. (5) With increase pressure velocity, stability also correspondingly. (6) decreases, increase, decreases.
