Question
1. What are the main functions of the hydraulic accumulator in hydraulic systems? thie hydralic accumalatorin hydralic 2. What are the differences betwean the pressure relief valve and the pressure reducing valve in function, configuration, and normal state of the valve (aormally closed or open), drain path of the fluid in the chamber where the adjusting spring is mounted (intemally drained or externally drained)? 3.If a two-way pressure compensated flow control valve is connected in the opposite way, namely, the inlet part and outlet part are interchanged, will the valve function as normal in the flow control? Analyze it 4. As shown in figure 1, an electro-hydraulic directional valve is used to control the direction of motion of the eylinder. But it is found that the cylinder cannot be activated (moved) when the solenaids are energized. What is the possible reason? ?Explanation / Answer
Answers
1)Hydraulic accumulator used as a pressure storage reservoir in which non-compressible fluid in under pressure that as applied an external force whenever necessary in the hydraulic system. the accumulator also used as :-
a) used as a shock absorber to damped out water vibrations.
b) it can act as a buffer to absorb fluid fluctuation in the hydraulic system.
2) answer in an attached file.
3) Pressure-compensated flow control valves are used with actuators that must move at a constant rate, regardless of pressure.
if pressure compensated valve connected to opposite port supplying fluid at a constant rate as whatever pressure is set in compensator valve. flow stays same at constant pressure the same regardless of inlet or outlet fluctuations.
4)solenoid valve is an electromechanical actuated valve to control the flow of liquids and gases.
the possible reason to not move cylinder i.e is inlet reservoir is not connected to inlet port of cylinder (from a figure)
