“…The main requirement of the laboratory testing device was to simulate a real hydraulic circuit of a farm tractor as closely as possible. That is why the hydraulic circuit components, cyclical load application and fluid temperature were selected based on technical and operational data of farm machinery and its real-life use (Tkáč et al, 2018). Machinery manufacturers have recently tried to introduce into hydraulic systems new plant-or synthetic-based fluids and oils that are more environmentally friendly, decomposable and less damaging to water resources.…”

The design of the experimental laboratory device is based on the construction of the hydraulic circuits of mobile devices. It is possible to ensure the repeatability of the flow characteristic measurements at the laboratory. This means that in the operating test it is possible to verify the flow characteristics of the hydraulic pump and these results are not affected by the change in the physical properties of the applied liquid. By comparing of the flow characteristics directly on the work equipment (mini-excavator, etc.), the disadvantage is the need for dismantling the hydraulic pump and its mounting on the laboratory device. In some working device removal is not possible, where dismantling is structurally difficult or is time consuming, which increases the cost of their operation.The proposed experimental laboratory device serves to verify the flow characteristics of the hydraulic pump and is also designed to be universal, to test external gear hydraulic pump and hydraulic pump with inclined plate.

Introduction. The article describes the test bench specialized software, developed for technical inspection of domestic and foreign volumetric hydraulic drives in repair enterprises and service centers. The results of bench tests using a hydraulic bench and software are presented. Materials and Methods For the application software development, G graphical programming language of the Laboratory Virtual Instrumentation Engineering Workbench (Lab- View) programming environment developed by the National Instruments Company has been used. The reliability of the results obtained has been confirmed by a series of bench tests of domestic and foreign volumetric hydraulic drives. Results. There has been developed and implemented new test bench software for the technical inspection of hydraulic drives of different models from domestic and foreign manufacturers in repair plants and service centers. The software is used to capture, process and store data from the sensors during testing, to calculate and output measurement data, to conduct nonlaboratory analysis of the testing process in graphical, textual and video formats, to calibrate sensors, and to store the test results in the electronic library system. The specialized software runs under the Microsoft Windows 7 x86 (32-bit) operating system and is installed on a personal computer of the hydraulic bench data processing unit. The developed software is characterized by the ergonomics of the user interface, the ability to control all the parameters of diagnosing the tested volumetric hydraulic drives. Discussion and Conclusion. Specialized software and the test bench permit high accurate monitoring of all technical condition parameters of the most common domestic and foreign volumetric hydraulic drives in accordance with the requirements of the manufacturers in the repair enterprises and service centers.

This paper deals with process of remanufacturing which is a process that is applied to products have expired or have been damaged, so the products can be reused with almost the same quality and balance as new products. PT UTR plant Jakarta has a new project, namely remanufacturing PT MCG's hydraulic cylinder. To maintain customer trust, each component that is remanufacturing must be ensured of its quality by means of testing before being sent to the customer. This equipment is made based on the use of management methods that have been standardized, namely 7++ ups tools. In collecting the required data, a direct approach was taken by following the existing remanufacturing process flow, so that the tool to be made was really useful and easy to use. From the results of the research carried out, we make a special equipment of a stand test bench hydraulic cylinders so that each component of the hydraulic cylinder that was remanufacturing could be done on a test bench. With this equipment, the quality standards of remanufacturing hydraulic cylinders can be accounted for.
