6 FAQs about [Piston pump accumulator]
How does a piston accumulator work?
A piston accumulator consists of a fluid section and a gas section with the piston acting as a gas-proof screen. The gas section is pre-charged with nitrogen. The fluid section is connected to the hydraulic circuit so that the piston accumulator draws in fluid when the pressure increases and the gas is compressed.
What is a HYDAC piston accumulator?
The compressibility of a gas (nitrogen) is utilised in hydro-pneumatic accumulators for storing fluids. HYDAC piston accumulators are based on this principle. A piston accumulator consists of a fluid section and a gas section with the piston acting as a gas-proof screen. The gas section is pre-charged with nitrogen.
What type of accumulator is best for a piston pump?
Bladder or diaphragm accumulators are the best types for dampening high-pressure spikes at the outlet of a piston pump. They respond quickly and prevent excessive wear on the bore and seals, unlike piston accumulators.
What is a gas-charged piston accumulator?
A gas-charged piston accumulator is a type of accumulator that has a free-floating piston with seals separating the liquid and gas. It operates and performs similarly to the bladder type, but can cost twice as much as an equal-sized bladder type in certain applications.
What is a threaded piston accumulator?
Our Threaded Piston Accumulator are completely repairable and refillable, which offers a great flexibility. Weight reduced piston accumulators are made with a plastic piston, made out of a high strength thermosetting composite material. The especially developed plastic piston owns the same high gas durability as the steel piston.
What is a spring-loaded piston accumulator?
A spring-loaded piston accumulator is identical to gas-charged units, but a spring forces the piston against the liquid instead of gas. Its main advantage is no gas to leak, but it's not suitable for high pressure and large volume.
