An accumulator is placed close to the pump with a non-return valve preventing flow back to the pump. In the case of piston-type pumps this accumulator is placed in the ideal location to absorb pulsations of energy from the multi-piston pump. [citation needed] It also helps protect the system from fluid hammer. This protects system components ...
The pump swivel angle covers both positive and negative flow direction. Disadvantages: The pump cannot be utilized for any other hydraulic function in an easy way and cooling can be a problem due to limited exchange of oil flow. High power closed loop systems generally must have a 'flush-valve' assembled in the circuit in order to exchange much ...
That implies the following main applications for a radial piston pump: machine tools (e.g., displace of cutting emulsion, supply for hydraulic equipment like cylinders) high pressure units (HPU) (e.g., for overload protection of presses) test rigs; automotive sector (e.g., automatic transmission, hydraulic suspension control in upper-class cars)
Each HPU consisted of an auxiliary power unit (APU), fuel supply module, hydraulic pump, hydraulic reservoir and hydraulic fluid manifold assembly. The APUs were fueled by hydrazine and generated mechanical shaft power to drive a hydraulic pump that produced hydraulic pressure for the SRB hydraulic system. The two separate HPUs and two ...
Only a few hydraulic power transmission networks are still in use; modern hydraulic equipment has a pump built into the machine. In the late 19th century, a hydraulic network might have been used in a factory, with a central steam engine or water turbine driving a pump and a system of high-pressure pipes transmitting power to various machines.
SMPC – subsea multiphase pump, which can increase flowrate and pressure of the untreated wellstream [citation needed] SN – seat nipple; SNAM – Societá Nazionale Metanodotti now Snam S.p.A. (Italy) [27] SNP – sidewall neutron porosity; SNS – southern North Sea; S/O – Slack Off; SOBM – synthetic oil-based mud; SOLAS – safety of ...
There are two specialized types of hydraulic intensifier used for water jet cutting.The first and most common is the inline hydraulic intensifier. Oscillating hydraulic pistons are used to compress water to the required pressure levels.
Be this source of the high pressure a pump (in case of liquid) or a gas compressor (in case of gas), the aim of the HIPPS in these cases is to reliably shut down the pump or the gas compressor creating the high pressure condition in a reliable and safe manner.
