“…Penelitian lain adalah penambahan Variabel Frequency Drive (VFD) pada motor pompa hydraulic power unit untuk mengatur frekuensi motor hidrolik yang menghasilkan efisiensi energi 80,65% [4]. Keuntungan lain dengan penggunaan VFD ini adalah temperatur kerja turun 65%, aliran oli turun 91%, noise yang muncul pada sistem turun 5,75%, dan sistem juga tidak berisik tapi lebih kuat dibanding tanpa menggunakan VFD [5].…”

Proses retrofit adalah proses penggantian atau penambahan suatu komponen ke mesin dengan tujuan untuk memberikan nilai tambah pada performa mesin tersebut. Pada penelitian ini, proses retrofit diaplikasikan pada penggantian penggerak drilling axis mesin Ficep H-beam Drilling LFB-200-49. Proses retrofit ini membutuhkan komponen motor servo sebagai energi penggerak dan ballscrew sebagai pengubah rotasi motor menjadi gerakan linear twist drill saat melakukan proses pengeboran untuk menggantikan sistem hidrolik yang digunakan sebelumnya. Pada perancangan retrofit yang dilakukan terhadap mesin Ficep H-beam Drilling ini, gaya dorong yang dihasilkan sistem hidrolik digunakan sebagai acuan untuk mengetahui kebutuhan dynamic load yang harus ditransmisikan oleh ballscrew sedangkan thrust axial force dari mata bor digunakan sebagai acuan dalam menentukan daya motor servo. Dalam merancang penggantian sistem hidrolik ke sistem motor servo ini, komponen yang disarankan adalah ballscrew dengan pitch 10 mm dan diameter poros ballscrew 38 mm yang memenuhi syarat transmisi dynamic load 50.210,56 N dan motor servo dengan daya 8,12 kW dengan penambahan gear ratio 3 : 1. The retrofit process is the process of replacing or adding a component to a machine with the aim of adding value to the machine's performance. In this study, the retrofit process was applied to the replacement of the Ficep H-beam Drilling LFB-200-49 drilling machine axis. This retrofitting process requires a servo motor component as driving energy and a ballscrew to convert the motor rotation into a linear twist drill motion during the drilling process to replace the hydraulic system used previously. In the retrofit design carried out on the Ficep H-beam Drilling machine, the thrust generated by the hydraulic system is used as a reference to determine the dynamic load requirements that must be transmitted by the ballscrew while the thrust axial force from the drill bit is used as a reference in determining the power of the servo motor. In designing the replacement of the hydraulic system to this servo motor system, the recommended components are a ballscrew with a pitch of 10 mm and a ballscrew shaft diameter of 38 mm which meets the requirements for dynamic load transmission of 50,210.56 N and a servo motor with a power of 8.12 kW with the addition of a gear ratio of 3. : 1.

“…An apparatus that controls the speed and rotational force, or output torque, of electromechanical equipment, is known as a variable speed drive (VSD) [32]. VSD applications have gained popularity recently due to the promise of significant energy savings [33]. Most of the industrial machinery powered by hydraulic systems is often operated largely in partial operating conditions.…”

With the growing cost of electrical energy, the necessity of energy-saving implementation in industries based on energy audits has become a major focus area. Energy audit results indicate energy-saving potential in an application and require the physical presence of the auditor’s team for monitoring and analyzing the energy consumption data. The use of Industrial Internet of Things (IIoT) for remote data monitoring and analysis is growing and new industrial applications based on IIoT are being developed and used by various industrial sectors. Possibilities of a mixed method of physical and remote energy audit using IIoT in industrial applications and its advantages as proposed in this research work needs to be explored. Existing hydraulic press machines running with direct online starter (DOL) can be run with variable speed drive (VSD) for energy saving but this requires an extensive energy audit. Key electrical and operational parameters of the hydraulic pump motor were monitored and analyzed remotely using IIoT in this research work by operating the hydraulic press with DOL and VSD motor control methods one by one. The input power factor of the hydraulic pump motor showed an improvement from 0.79 in DOL control to 0.9 in VSD control at different motor loads. The hydraulic pump motor starting current showed a reduction of 84% with VSD control. The hydraulic pump motor’s continuous current was reduced by 40% and 65% during the loading and unloading cycle, respectively, with VSD control. Electrical consumption was reduced by 24% as a result of operating the hydraulic pump motor at 35 Hz with VSD control without impacting the performance of the hydraulic press. These results indicated more efficient control by changing to VSD control in comparison with DOL control. A combination of physical and remote energy audits as performed in this research work using the proposed IIoT framework can be utilized for implementing energy saving in hydraulic presses thus motivating industries to adopt available more energy-efficient technologies at a faster pace.

As a new type of global energy-saving transmission mode, frequency conversion hydraulic drive system has been widely used. Since hydraulic systems become more complex and transfer more power, operating accidents often occur unexpectedly. Therefore, online monitoring of the running state of the hydraulic system is significant during its long-term operation. The pressure, flow, and vibration signals obtained by traditional monitoring methods are nonstationary and susceptible to disturbance. In order to solve this problem, a method of monitoring power condition of the motor driven hydraulic system based on input voltage and current of the motor is proposed. The present study uses the amplitude and phase information of the voltage and current signals on the stator side of the AC motor to form a dynamic power circle graph and extracts feature information from the graph to monitor the power state and its dynamic change process of the hydraulic system. Results obtained from experiments conducted under different frequencies and loads indicate that the proposed method can realize the online monitoring successfully and effectively. Furthermore, the method has another advantage of monitoring the dynamic power change process of the hydraulic drive system and the power matching process between the motor and the system load condition in a visualized way.
