| 500 ## - GENERAL NOTE | |
| General note | Hydraulic actuator is the main component in hydraulic power steering system of tractors<br/>and other hydraulic machinery. These actuators must be inspected to an acceptable<br/>level through an efficient inspection machine in order to prevent mechanical failure.<br/>Previous studies have shown that actuators with end of line quality testing perform<br/>well and enhance reliability and durability. Previous studies on analyzing industrial<br/>products through automated inspection machines make a significant contribution in<br/>the development of these products. In this research project , we have develop a fully<br/>automated hydraulic actuator test rig for hydraulic cylinder manufacturers for end of line<br/>quality testing. A series of advanced control valves combined with intelligent algorithm<br/>have been employed to measure the key performance parameters. Two external actuators<br/>have been connected with the central work piece actuator to enable the cylinder to cycle<br/>against an external load sufficient to maintain a constant operating pressure of 140 bar<br/>for 90,000 cycles. This will enable actuator to perform accordingly as per standard<br/>requirement in which total leakage shall not exceed 50ml/90,000 cycles. Hydraulic<br/>gear pump is used for fluid flow in the circuit. Hydraulic Pump is connected with<br/>eclectic 3-phase motor through couplings to transfer the hydraulic oil in hoses. Solenoid<br/>directional control valves, pressure distributor valve and pressure relief valves were used<br/>for maintaining the hydraulic oil pressure at 140 bar during endurance testing. Another<br/>test namely performance test has been performed on the hydraulic actuator in which<br/>piston keeps in between 25 mm and pressure on one side of the piston keeps at 240 bar<br/>for 1 minute and then pressure reduces to zero and than again pressure increases to 20<br/>bar for 5 minutes. Same procedure was repeated on the other side of piston. Standard<br/>for this test requires no external leakage and internal leakage is set to be not exceeded<br/>than 5ml/minute during pressure test. Results of endurance test shows that leakage was<br/>not exceeded than 50ml/90,000 cycles. Results of performance test shows no external<br/>vi<br/>leakage and internal leakage was not exceeded than 5ml/minute. The project research<br/>present an effective procedure to quality check hydraulic actuators with proof of the<br/>concept to actuators manufacturers. The new procedure is a significant improvement<br/>towards manufacturing more reliable actuators |
