The role of accumulator hydraulic system is pressurized oil stored in the need for time and re-emit. Its main role in the following aspects. Implementation of certain components of the hydraulic system for the auxiliary power supply is intermittent operation, the total working time is very short, the implementation of some components of the hydraulic system, though not intermittent operation, but within a work cycle (within a stroke or a) speed varies greatly. After setting the accumulator in such a system can use a smaller pump power to reduce the power of the main drive, so that the size of the entire hydraulic system is small, light weight, and inexpensive. For emergency power source for some systems require that when a pump failure or power outage (for oil actuators suddenly interrupted), the actuator should continue to complete the necessary action. For example, for security reasons, the hydraulic cylinder piston rod must be retracted into the cylinder. In this case, the need for an accumulator of appropriate capacity for emergency power source. Added to maintain constant pressure leaks and the actuator does not operate for a long time, and to maintain a constant pressure system, the accumulator can be used to compensate for the leakage, so that a constant pressure. Due to the sudden hydraulic shock absorbing commutation valve, hydraulic pump suddenly stop motion actuator suddenly stopped, and even human in need of emergency brake actuators and other reasons, will make the liquid flow inside the pipe changed dramatically, and have an impact pressure (oil strike). Although the system has a safety valve, but still inevitably generate pressure surge and short-term impact. This impact pressure, often caused by instrumentation systems, components, and sealing device malfunction or even damage the pipe rupture, the system will also produce significant vibration. If before the control valve or the installation of a hydraulic cylinder impact source accumulator can absorb and mitigate such impacts. Absorb pulsation, reducing the noise of the pump pulsation flow causes pressure pulsation, so that the movement speed of the actuator is uneven, vibration and noise. At the outlet of the pump in parallel with a responsive and small inertia accumulator can absorb pulsating flow and pressure to reduce noise. [Company Name] Tengzhou Machine Co., Ltd.
