The cleanliness of the hydraulic rotary actuator oil circuit is directly related to its operational stability and service life and requires regular cleaning. There is no fixed standard for its cleaning cycle, which is mainly determined flexibly by the structure of the hydraulic system and the degree of contamination. The following is a concise and practical method for cleaning the oil circuit:
First, clean the oil tank and pipelines. Use a volatile and residue-free cleaning solvent to thoroughly clean the hydraulic system oil tank. After removing oil stains and impurities from the inner wall, purge with precision-filtered dry air to remove solvent residues; then clean the pipelines. For severely contaminated or structurally complex pipelines, it is necessary to disassemble the pipelines and joints for immersion treatment to ensure thorough cleaning.
Second, install protective components. Install a dedicated oil filter that meets the system requirements in the hydraulic rotary actuator pipeline to focus on protecting the oil supply and pressure pipelines of the hydraulic valve; for precision valves such as electro-hydraulic servo valves, install a flushing plate on the collector instead to ensure good sealing and unobstructed oil circuit.
Finally, perform cleaning inspections. Check whether the pipeline size is matching and the connection is firm and correct; if the system uses an electro-hydraulic servo valve, the flushing plate must ensure that the oil flows from the oil supply pipeline to the collector and directly returns to the oil tank to achieve cyclic flushing. During flushing, check the oil filter every 1 to 2 hours, do not open the bypass, and replace the oil filter immediately if blockage is found.
If you need to consult about the details of hydraulic rotary actuator oil circuit cleaning, the model of suitable oil filter or flushing precautions, you can communicate at any time, and we will provide you with accurate practical guidance.

Standardizing installation and commissioning, controlling working parameters and following operation points can ensure the stable operation of the hydraulic rotary actuator and avoid initial use failures.
Factors Influencing Coaxiality of Hydraulic Cylinders, Inspection Methods and Precautions (Part II)
This article focuses on the influencing factors, inspection methods, influence of installation forms and hazards of improper control of the coaxiality of hydraulic cylinders. It clarifies that coaxiality errors mainly come from the accuracy of the mounting base, welding deformation, parallelism of the guiding mechanism and inadequate detection and adjustment. For error control, it introduces three common on-site inspection and alignment methods such as micrometer inspection and laser alignment detection. At the same time, it analyzes the focus of coaxiality control for different installation forms, points out that excessive coaxiality deviation will aggravate equipment loss and increase maintenance costs, and emphasizes the importance of no-load trial operation and precision records after installation. It provides comprehensive guidance for on-site control, error correction and later maintenance of the coaxiality of hydraulic cylinder installation.
This article focuses on analyzing the core concept and core technical requirements of hydraulic cylinder mounting coaxiality, clarifying that coaxiality is the key to ensuring the stable operation of hydraulic cylinders and the complete machine. Its core is to ensure the coincidence degree between the hydraulic cylinder axis and the relevant mounting reference axis, mainly involving three dimensions of coaxial matching: cylinder barrel and piston rod, hydraulic cylinder and load movement direction, and hole positions of front and rear mounting supports. At the same time, it is pointed out that the coaxiality control standard shall be flexibly determined according to the equipment type, stroke length and working conditions, with different control focuses in different scenarios, and the longer the stroke, the higher the requirement for coaxiality accuracy, providing basic cognition and technical guidance for the preliminary control of hydraulic cylinder mounting coaxiality.
Precautions for the Operation of Newly Installed Hydraulic Rotary Actuators
The core principle of the operation of the newly installed hydraulic rotary actuator is "stability" rather than "speed". Mastering the three core skills of "low-speed running-in to discharge air, full-process self-inspection to troubleshoot hidden dangers, and gradual loading for standard operation" will take a small amount of time, but it can effectively avoid faults such as abnormal noise, crawling and oil leakage, reduce maintenance costs and construction period losses, extend the service life of the hydraulic rotary actuator, and ensure the smooth progress of the project.
Hydraulic Rotary Actuator Installation Science: Avoid Forced Installation Mistakes
The core principle of hydraulic rotary actuator installation is "stability" rather than "speed". Although pre-source dimensional verification and 4 on-site self-inspections will take a small amount of time, they can effectively avoid problems such as actuator rod scratches, lug seat damage, and rework delays. For engineering construction, "slow work yields fine products". Doing a good job in every inspection before installation can truly reduce losses, save costs, and ensure the smooth progress of the project.
