Resistance, then liquid be introduced into the first collecting tank, then by shunting liquid bath during radiated, enter back into the second collection
Liquid bath, finally leaves protecting against shock accumulation of energy radiator from liquid outlet；It is larger in the shunting liquid bath internal resistance of protecting against shock accumulation of energy radiator
When, because the pressure in now accumulation of energy pipe is smaller, some liquid is entered in accumulation of energy pipe, as liquid is in accumulation of energy intraluminal fluid
The rise of position, the air in compress energy storage pipe so that the pressure in accumulation of energy pipe is also raised, the pressure in final accumulation of energy pipe reach with
Pressure at inlet is equal, and now the liquid velocity at inlet slows down, and the pressure at inlet also reduces therewith, with entering
Pressure at liquid mouthful reduces, and into the liquid in accumulation of energy pipe because pressure is higher than at inlet, returns into the first collecting tank
It is interior, then radiated during by shunting liquid bath, enter back into the second collecting tank, finally leave protecting against shock from liquid outlet
Accumulation of energy radiator.
Because the motility of air is good, substantially without hysteresis quality, air, which runs into, in protecting against shock accumulation of energy radiator impact
The moment of power, just compress and act immediately, this action is completed in moment, there will not be hysteresis quality as mechanical damping and be used
Fatigue.
