What should I do if the flow stability of a bladder accumulator is poor? If you’re not sure, take a look at the introduction in this article. Today, the editor will introduce effective solutions.
- Accumulator not functioning
This is mainly because the air valve is severely leaking, there is no nitrogen inside the skin bag, or the skin damage of the skin bag causes oil to enter. When p0>p2, that is, the working pressure is too low, it can also cause the accumulator to lose its proper energy storage function. In order to fully utilize the energy accumulator’s ability to absorb pulsating pressure, the distance between each connecting pipeline at the branch point of the main pipeline should be short, the diameter should be large, and it should be as close as possible to the source of pulsation, otherwise it will cause significant pressure pulsation and affect the effectiveness of energy storage.
- Poor stability of the flow released by the accumulator
For an accumulator, the instantaneous flow rate of the charging and discharging liquid is a variable, when it comes from a large capacity and Δ In a system with a large range of p=p2-pl, in order to obtain a relatively constant and large instantaneous flow rate, the following measures can be taken to improve it.
① A flow control device can be added between the accumulator and the actuator.
② Using several small capacity bladder accumulators in parallel to replace a large capacity accumulator, different charging pressures can be used between several small capacity accumulators.
③ Working pressure range Δ P should be minimized as much as possible, or the structural capacity of the accumulator can be appropriately increased.
④ During the entire working cycle, it is necessary to arrange the filling time reasonably to ensure sufficient filling time, avoid internal leakage problems in the system during the filling period, and ensure that the pressure can reach p2 during the filling process.
