Hydraulic system flushing is a crucial step, primarily designed to remove impurities generated during the manufacturing and installation processes. This ensures the cleanliness of the system, thereby enhancing equipment stability and extending its lifespan. Below is a further interpretation and analysis of the aforementioned content:
The Importance of Hydraulic System Flushing
Oil contamination in hydraulic systems is a primary cause of failure. During the manufacturing and installation of hydraulic systems, impurities may remain in the piping due to pre-installation, disassembly, transportation, storage, installation, and welding processes. Therefore, flushing the hydraulic system is highly necessary.
Washing methods and washing circuit layout:
The choice of flushing method and the layout of the flushing circuit directly impact the flushing effect and time. To improve flushing efficiency, it is necessary to select the appropriate flushing flow rate and method, and to rationally arrange the flushing circuit.
Cautionary Notes During the Washing Process:
During the rinsing process, the following points should be noted:
Valve blocks, pipe interfaces, and pump group inlets and outlets must be securely sealed with clean tape to prevent secondary contamination on-site.
Regularly inspect the degree of contamination in the filter cores and replace them promptly.
Regulate the washing oil temperature between 40-70℃ as per specifications. Excessive oil temperature can lead to a decrease in dynamic viscosity, an increase in flow rate, and a higher Reynolds number. The typical range for the Reynolds number during washing is 2000-4000.
During the hydraulic system flushing, regular inspections are required to promptly address issues such as pipeline oil leakage. At the same time, attention must be paid to changes in oil temperature and pressure to ensure the normal operation of the system.
All hydraulic cylinders, motors, and energy storage devices, as well as the flushing circuit, have been disconnected to ensure effective flushing and equipment safety.
Hydraulic system trial run and stable operation:
Through effective flushing, a solid foundation is laid for the trial operation and stable performance of the hydraulic system. During the trial operation, it is crucial to closely monitor the system's operating status and changes in various parameters, making timely adjustments and optimizing system performance. Similarly, during operation, regular maintenance and inspections of the hydraulic system are necessary to ensure its stability and reliability.
