DESIGN of SPEED CONTROL of HYDRAULIC MOTOR

-This study is about Hydraulic Power Pack in hydraulic system Hydraulic drives and controls have become more important due to automation and mechanization. A large number of the advanced and incredible machineries are controlled partly or totally by hydraulics. Hydraulic system is less convoluted and has less moving parts. Today drive and control framework designing is unfathomable without hydraulics. Hydraulic Power Pack gives energy to the activities of the water driven framework, likewise moves the liquid through the framework, gives a protected greatest framework working pressing factor, and furthermore helps with keeping up the liquid temperature and tidiness. Water driven Power Pack is chosen by Pressure range, ostensible force and Size of tank different boundaries.

The main goal of the research done in this paper is to examine possible improvements in energy efficiency of the hydraulic power systems and with this lower gas emission from working machinery. It is here given a brief explanation of the existing hydraulic systems putting special attention on a hydraulic system with separate meter-in and separate meter-out (SMISMO). While the aim of this research is to improve the hydraulic energy efficiency mainly using the SMISMO system, additional research on using those systems for simultaneous speed and pressure control of the cylinders is also observed. The results obtained through experimental studies will be used to further improve the hydraulic system. Further upgrade of this system is to design automated SCADA system for improved data acquisition and control the valves in servo systems.

Test Result

One of very important and vital tool in road marking is road mark erasing machines. In general, the machine used to repair road markings is a road marking erasing machine that is pushed manually. However, this machine has a disadvantage that requires a long time in the process of erasing the road marking, so making it less efficient. Therefore, the truck road mark erasing machine is one of the options to replace the erasing machine that is pushed manually. The machine uses a grinding system with a vertical blade eraser position and hydraulic power to drive the blades as it is able to withstand shock loads and thrust upwards due to the removal process, having overload protection, and the size of components are not large. The study started with doing observation to the existing manual erasing machine, then determining the required blades and calculating as well as selecting the required components of the hydraulic system. Based on the calculation, the blade specification was obtained and selected, i.e surface milling cutter of type WFX12200R from Sumitomo Electric Hardmetal Corporation having rotation speed 750 rpm, hydraulic motor from Danfoss of type OMR-80 having torque 136 Nm dan displacement 80.3 cc/rev., and using hydraulic pump from Parker of type 0210 having displacement 21 cc/rev. From the test result in the field, this machine is three times faster than the manually pushed machine, less number of the blade used, and the engine as a resource on the machine is more durable.
