Testing method and maintenance of hydraulic cylinder settlement of excavator

In general, if there’s no external leakage, rapid settlement of the hydraulic cylinder often indicates a leak in the load oil circuit. To assess the sealing integrity of hydraulic cylinders, the most straightforward method is to perform a sealing test (remember to prioritize safety during the process). A. When performing the boom settlement and sealing test, first position the boom and bucket at a 90-degree angle. Seal the oil ports and lines in the bottom chamber of the boom hydraulic cylinder, then start the engine and raise the bucket to hover slightly above the ground to measure the settlement rate. B. For testing the bucket rod's settling and sealing, first extend the bucket rod until the bucket touches the ground. Block the oil ports and lines in the rod chamber, start the engine, elevate the boom, and lift the bucket off the ground to take measurements. The method for testing the bucket cylinder settlement follows a similar procedure. Rapid settlement in an excavator’s hydraulic cylinder can result from several factors: 1. Leakage within the hydraulic cylinder itself; 2. Internal leaks at the valve holes or valve stems of the control valve; 3. Malfunctioning overload safety valves; 4. Valve stems not being properly centered.
