According to the safety modulus of hydraulic hose ruled by international standard, we recommend that the working pressure is one forth of the minimum blast pressures.
按照有关国际标准规定的液压胶管的安全系数，我们推荐的工作压力通常为胶管最低爆破压力值的四分之一。

It was shown by calculation results that the flow ripple and fluid noise of hydraulic pump increased seriously when the bulk modulus descended.
结果表明，随着油液体积弹性模量的下降，泵的流量脉动及流体噪声均增大。

However, because of the high elasticity modulus and low viscosity of seawater, there is serious vibration in seawater hydraulic relief valve.
