Why Komatsu PC200-6 Hydraulic Pump System Work Powerlessly,CMP Know-how Co., Restricted


Briefly, the powerless of PC200-6 is mainly due to the poor oil quality of the hydraulic oil. Subsequently, replacing the hydraulic oil filter on time (specified to be changed each 500 hour) and taking note of monitoring the hydraulic oil quality (viscosity, fluidity and presence or absence of suspended solids) is the key to avoiding or lowering such failures.

Features of Sauer PV pump

The total-size shaft with a excessive environment friendly tapered roller bearing association affords a excessive loading capacity for external radial forces. Further pumps could be constructed on. The hydro-mechanical servo displacement management maintains the selected swash plate place and therefore pump displacement. Upon launch of the management handle, the swash plate mechanically returns to the null position and the movement change into zero. High case pressures will be archived without leakage even at the lowest temperature by utilizing suitable shaft seals. The servo valve arrangement affords the facility to incorporate operate regulators and remote management system. Axial piston items are designed for simple servicing, complete dismantling and reassembly might be carried out standard hand instruments, and all parts or sub-assemblies are replaceable.

Essentially the most interesting factor about this 4-pump meeting is its torque limiting management, which gives the sum of torque limiting operate for both piston pumps and the bigger gear pump. The swashplate of the piston pump is biased by a very sturdy double coil spring, and should you have a look at the end cowl, you’ll see that it’s destroked not by one, however by three servo-pistons, each related to a separate pump. In this arrangement the swashplate position is affected by the sum of power each servo-piston is creating, together with the rotary group piston induced drive that acts directly on the swashplate. The size of the servo-pistons, the double spring fee and the valve plate pressure carry-over angle are chosen in a approach that the piston pump regularly destrokes because the outlet pressures rise, permitting the three pump combination to comply with a desired fixed power curve.
