In practical work, especially in some large-scale Hydraulic system In order to ensure that the whole system can maintain a relatively stable working state, we often set up two circuits to achieve the purpose, namely, pressure maintaining circuit and pressure relief circuit. So, in Design of hydraulic station What are the pressure maintaining circuit and pressure relief circuit of the hydraulic cylinder? Let's briefly introduce this problem.
In fact, they all play a very important role. The main function of the pressure maintaining circuit is to keep the system pressure basically constant when some actuators in the hydraulic cylinder stop or deform suddenly, so as to reduce the loss. The main function of the voltage holding circuit is to make the system slowly release the energy stored during the holding period, so as to avoid the impact or noise caused by sudden release.
In fact, they all play very important characters. The key function of the pressure maintaining circuit is to maintain the working pressure foundation of the system software unchanged when some electric actuators in the hydraulic cylinder suddenly stop or deform, so as to minimize the damage. The key function of the pressure relief circuit is to make the system software slowly release the kinetic energy stored in the pressure holding period, so as to prevent the impact or noise caused by sudden release.
Naturally, for different hydraulic transmission systems, setting the circuit is also different. For some system software with high curing characteristics, we must select the appropriate circuit setting, so that the working pressure of the upper chamber of the hydraulic cylinder can be automatically maintained in a certain range and relatively stable. When the working pressure is released, we can operate it according to the sequence valve to keep it for a long time when the working pressure is released.
This paper introduces the two circuits and their different functions in the hydraulic cylinder, hoping that the introduction of these contents can help us to better use these devices.
