Why Komatsu PC200-6 Hydraulic Pump System Work Powerlessly CMP Know-how Co. Limited
In short, the powerless of PC200-6 is mainly due to the poor oil high quality of the hydraulic oil. Therefore, replacing the hydraulic oil filter on time (specified to be changed every 500 hour) and listening to monitoring the hydraulic oil high quality (viscosity, fluidity and presence or absence of suspended solids) is the important thing to avoiding or lowering such failures.

Features of Sauer PV pump
The total-length shaft with a high efficient tapered roller bearing arrangement gives a excessive loading capability for external radial forces. Extra pumps will be constructed on. The hydro-mechanical servo displacement control maintains the selected swash plate place and hence pump displacement. Upon launch of the management handle, the swash plate routinely returns to the null place and the movement grow to be zero. High case pressures might be archived without leakage even at the lowest temperature by utilizing appropriate shaft seals. The servo valve arrangement gives the facility to incorporate perform regulators and distant control system. Axial piston models are designed for easy servicing, full dismantling and reassembly will be carried out customary hand tools, and all parts or sub-assemblies are replaceable.
The most attention-grabbing factor about this four-pump meeting is its torque limiting control, which supplies the sum of torque limiting function for both piston pumps and the larger gear pump. The swashplate of the piston pump is biased by a very robust double coil spring, and in case you look at the tip cowl, you will see that it is destroked not by one, however by three servo-pistons, every connected to a separate pump. In this arrangement the swashplate place is affected by the sum of power each servo-piston is creating, together with the rotary group piston induced power that acts directly on the swashplate. The size of the servo-pistons, the double spring price and the valve plate stress carry-over angle are selected in a means that the piston pump progressively destrokes as the outlet pressures rise, allowing the three pump mixture to comply with a desired fixed energy curve.
