Product Description

Rexroth A10VD43 Hydraulic Pump Parts Durable Cast Iron Construction Industrial Machinery Manufacturing Plants and Repair Shops

The main hydraulic pump functions as the primary power core of an excavator’s hydraulic circuit system. It is driven by the engine to convert mechanical energy into high-pressure hydraulic energy and transport pressurized fluid to hydraulic motors, actuating all operational movements of the excavator. Engineering excavators mostly adopt axial variable displacement piston pumps as their main hydraulic power units. Medium and large construction machines are fitted with integrated twin main pumps and a rear pilot gear pump assembly. Two autonomous high-pressure oil supply pipelines feed the main control valve to enable composite working actions, with a standard working pressure ranging from 28MPa to 35MPa. The tail-end low-pressure pilot pump operates at 3 to 4MPa with low flow output, supplying pilot pressure oil for control handle and main valve spool operation. Piston assemblies fixed in the cylinder block and pump housing rotate with the main shaft, finishing oil suction and pressure build-up procedures. Adjustments to the swash plate’s inclination angle modify piston stroke length, thereby altering the pump’s displacement capacity. The external servo regulator drives swash plate movement according to hydraulic feedback signals. A larger swash plate angle boosts fluid flow and operation speed, while a smaller angle cuts fuel consumption and eliminates engine stalling problems. The valve plate separates low-pressure inlet and high-pressure outlet channels to achieve hydraulic oil distribution. Three advanced control systems are integrated into the pump. Constant power control automatically lowers pump displacement as load increases, protecting the engine and optimizing overall power utilization rate. The LS load-sensing system delivers on-demand fluid flow and maintains low displacement at idle status to achieve fuel-saving effects. The HP pressure limiting function minimizes pump displacement at peak pressure to prevent hydraulic pipelines and cylinders from cracking damage. Typical malfunctions include internal leakage caused by piston abrasion, valve plate damage or regulator blockage, resulting in slow operation and power deficit. If the regulator is fixed at maximum displacement, the engine will suffer overload, emit black smoke and stall under heavy working loads. Severe internal leakage converts pressure loss into thermal energy, causing abnormal hydraulic oil overheating. Air entering the hydraulic system, inadequate oil volume, and damaged bearings or pistons will induce abnormal running noise. Routine maintenance includes timely replacement of hydraulic oil and filters to avoid wear on precision internal parts. Guarantee tight sealing of suction pipelines to prevent air suction and machine vibration, and keep hydraulic oil at the specified level to ensure stable pump working efficiency.
