Why Komatsu PC200-6 Hydraulic Pump System Work Powerlessly,CMP Technology Co., Limited

In short, the powerless of PC200-6 is mainly due to the poor oil high quality of the hydraulic oil. Due to this fact, replacing the hydraulic oil filter on time (specified to be replaced every 500 hour) and paying attention to monitoring the hydraulic oil quality (viscosity, fluidity and presence or absence of suspended solids) is the important thing to avoiding or reducing such failures.

Features of Sauer PV pump

The complete-length shaft with a high efficient tapered roller bearing arrangement provides a excessive loading capacity for external radial forces. Additional pumps will be constructed on. The hydro-mechanical servo displacement control maintains the chosen swash plate place and therefore pump displacement. Upon release of the control handle, the swash plate robotically returns to the null place and the circulation develop into zero. High case pressures might be archived without leakage even at the lowest temperature by using suitable shaft seals. The servo valve arrangement presents the facility to incorporate function regulators and remote management system. Axial piston items are designed for simple servicing, full dismantling and reassembly might be carried out customary hand tools, and all elements or sub-assemblies are replaceable.

Probably the most fascinating thing about this 4-pump assembly is its torque limiting control, which supplies the sum of torque limiting perform for each piston pumps and the bigger gear pump. The swashplate of the piston pump is biased by a really robust double coil spring, and in case you take a look at the end cowl, you may see that it is destroked not by one, however by three servo-pistons, every connected to a separate pump. On this arrangement the swashplate place is affected by the sum of drive every servo-piston is creating, together with the rotary group piston induced pressure that acts directly on the swashplate. The size of the servo-pistons, the double spring rate and the valve plate strain carry-over angle are selected in a means that the piston pump steadily destrokes as the outlet pressures rise, permitting the three pump mixture to observe a desired constant energy curve.
