Solution

Aimed at foreign buyers with large-scale procurement needs, this solution leverages our factory’s strong production capacity and direct supply model to eliminate intermediate links. For example, we once provided 500 sets of hydraulic pumps and 300 sets of travel components for a European construction company, offering a 18% price discount compared with the industry average. We completed the production with a 100% on-time delivery rate, helping the client reduce 22% of procurement costs and gain a competitive advantage in the local market.

Focusing on the diverse needs of foreign markets, we provide customized production services. For instance, aiming at the high-temperature and dusty working conditions in the Middle East, we customized heat-resistant and dust-proof hydraulic components for a Middle Eastern client, which increased the service life of the parts by 30%. We completed the customization and mass production of 400 sets of components within 8 working days, and provided Arabic technical guidance, fully meeting the client’s local usage needs.

1. Installation Precautions   Heavy-Duty Lifting: Given the massive weight of the PC2000-8 assembly, utilize high-capacity lifting equipment and ensure the chassis is securely supported. Hydraulic Air Bleeding: Thoroughly clean all interfaces before connection. After installation, air bleeding and pre-filling via the motor’s bleed plug are mandatory before startup to prevent motor seizure caused by dry rotation. Torque & Sealing: Mounting bolts must be treated with thread locker and tightened to ultra-high torque specifications. Closely inspect the floating seal contact surfaces to ensure no damage occurred during assembly.   2. Troubleshooting Solutions   Tracking Deviation or Weakness: Prioritize measuring the travel pilot valve pressure. If pressure is normal, the issue is typically internal leakage caused by a worn distributor plate in the motor. Final Drive Abnormal Noise: This often indicates abnormal gear meshing or bearing failure. Perform an immediate oil analysis; if significant metallic fragments are found, a full teardown is required to prevent housing destruction. Leakage Management: Oil leaks at the sprocket hub usually signify floating seal failure. Immediate replacement is critical to prevent abrasive contaminants from entering and destroying the precision gear train.

I. Installation Precautions Alignment & Backlash: Ensure the mounting surface is level and pristine. Precise alignment with the swing ring gear is critical; verify the meshing clearance (backlash) to prevent excessive stress and premature wear. Torque Management: Fasten mounting bolts to the specified torque using a symmetrical, alternating pattern. This ensures uniform load distribution and prevents housing deformation or bolt loosening under vibration. Pre-lubrication: Fill with the designated grade of gear oil to the required level before startup. Dry operation must be strictly avoided to prevent immediate seizure of bearings and gears. II. Troubleshooting Solutions Abnormal Noise/Vibration: This typically indicates internal bearing failure or gear tooth damage. Immediate shutdown and inspection are required to prevent secondary damage from metal debris. Oil Leakage: Inspect skeletal oil seals or floating seals for wear or aging. Ensure the breather plug is unobstructed, as internal pressure buildup from blockages is a primary cause of seal failure. Loss of Power or Jerky Movement: Monitor oil cleanliness. If the lubricant contains metallic particles, flush the gearbox and replace the oil immediately. Routine oil analysis is vital for preventing catastrophic mechanical failure. Maintenance Tip: It is highly recommended to perform the first oil change within the initial 100 operating hours after installing a new reduction unit. This ensures the removal of microscopic metal debris produced during the run-in stage, safeguarding the internal components.

1.Installation Precautions System Cleanliness: Flush the entire hydraulic circuit and replace the oil before installation; even microscopic contaminants can cause spool seizure. Accurate Hose Labeling: Strictly label all hydraulic lines to prevent incorrect connections, which can lead to operational logic errors. Torque & Sealing: Tighten mounting bolts symmetrically to specified torque to avoid housing deformation. Always replace O-rings with new ones and apply a light coat of hydraulic oil. 2.Troubleshooting Solutions Slow or Weak Response: Prioritize inspecting the Main Relief Valve pressure settings and verifying if the pilot control pressure meets OEM specifications. Hydraulic Drift (e.g., Boom Dropping): This usually indicates internal leakage due to worn spools/bores or a faulty Overload Valve. Spool Seizure/Sticking: Typically caused by contamination or a broken return spring; requires a full cleaning of the valve block and oil quality analysis. External Leakage: Inspect seals for aging and check return line backpressure, as excessive pressure can compromise the spool oil seals.

1.Key Installation Precautions   System Contamination Control: Prior to installation, the hydraulic tank must be flushed, and all filters (return and pilot) must be replaced. Ensure all hose connections are pristine to avoid particle ingress. Mandatory Priming: One of the most critical steps is to pre-fill the pump casing with clean hydraulic oil through the drain port before startup. Air Bleeding: Bleed air from the system until a steady stream of oil is observed. This prevents “dry-start” cavitation, which can destroy a new pump within seconds.   2.Troubleshooting Matrix   Abnormal Noise/Cavitation: Usually caused by air leaks in the suction line or a clogged suction strainer. Verify all seals and hose clamps on the low-pressure side. Loss of Hydraulic Power: Often indicates internal leakage due to wear on the “tri-friction pairs” (cylinder block/valve plate). Requires resurfacing of the mating parts or regulator adjustment. Engine Stalling (Engine Bogging): This indicates that the pump is drawing more power than the engine can supply. Check for stuck PC or LS valves in the regulator and recalibrate as per OEM specs. Overheating: Excessive heat is a sign of high internal bypass. If the drain line flow is excessive, it indicates severe internal wear requiring a comprehensive seal kit replacement or component overhaul.
