FAQ;
Maintenance & Replacement
Q1: What precautions should be taken when disassembling and assembling the pump?
A23: Disassembly and assembly precautions: 1) Preparation: Clean the pump surface, place it on a clean workbench, and prepare special tools (Rexroth disassembly tool kit recommended); 2) Marking: Mark the relative positions of the pump body, end cover, and shaft to ensure correct reassembly; 3) Disassembly order: From the control device (PZB13) → end cover → swashplate → piston cylinder → valve plate → shaft; 4) Part protection: Place precision parts (pistons, valve plates) on a soft rubber pad, avoid collision; 5) Cleaning: Clean parts with diesel oil or special hydraulic parts cleaner, dry with compressed air (low pressure); 6) Assembly torque: Tighten bolts according to specifications (e.g., end cover bolts: 25 N·m, control valve bolts: 15 N·m); 7) Post-assembly test: Manually rotate the shaft (should be smooth), and conduct a pressure test after installation.
Q2: How to judge whether the pump parts are worn and need replacement?
A24: Wear judgment standards: 1) Piston-cylinder pair: Measure the inner diameter of the cylinder and the outer diameter of the piston (clearance > 0.02 mm → replace); 2) Valve plate: Check for scratches (depth > 0.01 mm) or uneven wear (replace); 3) Swashplate: Check the sliding surface for indentations or unevenness (runout > 0.03 mm → replace); 4) Bearings: Rotate by hand (if there is stuck or abnormal noise → replace); 5) Shaft: Check for bending (radial runout > 0.02 mm) or scratches (depth > 0.05 mm → repair or replace); 6) Control valve core: Check for wear (clearance with valve sleeve > 0.015 mm → replace); 7) Seals: Check for aging, cracking, or deformation (replace immediately if any of these occur).
Q3: What should be paid attention to when storing the pump (for spare parts or during shutdown)?
A25: Storage precautions: 1) Environment: Store in a dry, ventilated, and dust-free warehouse (temperature 5-30℃, humidity ≤60%); 2) Anti-rust treatment: Inject anti-rust oil into the pump inlet and outlet, plug the ports with plastic caps, and apply anti-rust grease to the shaft extension; 3) Placement: Place the pump horizontally on a wooden pallet (avoid vertical placement to prevent deformation of the shaft); 4) Regular inspection: For long-term storage (more than 6 months), rotate the pump shaft 180° every 3 months to prevent bearing rust; 5) Packaging: For transportation or long-term storage, use waterproof and shockproof packaging (wooden box with foam padding); 6) Shutdown storage: If the pump is installed on the machine and not used for more than 1 month, drain the hydraulic oil, inject anti-rust oil, and cover with a dust cover.
