Degassing the hydraulic energy storage tank

What are the components of a degassing device?

The degassing device consists of a pneumatic distributor 6, an air filter 7, check valves 8 and 9, a pneumatic cylinder 10 (as a vacuum pump) and a stand 11. The hydraulic accumulator is installed on the drain line connected to the suction line of the pump through the valve 3 (with two fixed positions).

What are the physical methods for degassing working fluid?

The known physical methods for degassing working fluid include: incubation in hydraulic tanks, mechani-cal destruction of bubbles, filtration, evacuation, cavitation, centrifugation, and others. Each of these methods has its own drawbacks.

Can a hydraulic accumulator be degassed without affecting pump operation?

It is concluded that the working fluid can be degassed without affecting pump operation. Due to the absence of a mechanical drive and throttling, the system allows more effi-cient use of drive energy. Keywords: hydraulics, hydraulic accumulator, liquid, pressure, vacuum, degassing, pump charging.

Does degassing affect the process of suction?

Due to the cyclical nature of the system (recharge and degassing), degassing does not affect the process of suction of the working fluid by the pump, which will allow for the application of a higher negative pressure and thus increase the efficiency of degassing.

Does degassing take place?

In this case, degassing does not take place. Charging and degassing are carried out cyclically. At pressures below the set value, the discharge line af-ter the accumulator is blocked by the hydraulic distributor, while the accumulator is charged and the working fluid is drawn in from the hydraulic tank.

Can working fluid be degassed without affecting pump operation?

The article reveals the principle of operation of a combined system for degassing working fluid and pump charging by means of a hydraulic accumulator for hydraulic systems with working bodies in the form of hydraulic cylinders. It is concluded that the working fluid can be degassed without affecting pump operation.
