We also service all kinds of pumps and most of the valves especially those of Bosch Rexroth and Moog. I can’t see that being the case. This is where the flow control works.
You probably know very well how a pressure relief on a LS line work. If disabled the store default currency will be shown. It is not directly changing the flow, just the pressure. By looking at the schematic, it suggests the pump to be a power control pump i. However, the pictures do not tell the same story. Yes one could view it as the regulator is trying to keep a constant deltaP across that 1mm orifice it does for sure but pjmp view is not helpful in this application since the orifice sits in a T’ed of branch of the main flow.
The margin compensator should be pkmp to BAR and when the proportional valve is switched off, there is no pressure on the “x” port and so the pump will sit at the standby pressure. As an example, simply connecting the LS port to the P port of an LS pump will force the pump up to maximum flow. This is how this system is connected as well with the addition of a proportional pressure relief valve on the LS signal line. A10VSO Variable displacement a10vo power control The pump part number and controller matches what is shown on the drawing.
Please help me out. Year of Establishment I can only explain a10vsl principle of operation with information available at this time. Without such an orifice the small pressure relief valve could become saturated and loose it’s function.
It could like 73lafuite suggested, it is simply running on high power for a short period of time. As always, if it’s not pimp The point at which the pump flow rate will start to reduce is therefore determined by the setting of the proportional relief valve provided it is set lower than the load pressure. Proportional to the drive speed and displacement, the flow can be smoothly adjusted by a110vso the swash plate position.
The spring of the controller now pukp tries to increase the flow but the resultant pressure drop again reduces the flow. The strategy of the pump controller is to always maintain that pressure.
A10vo will never get full pump flow across the orifice, the delta P over the orifce is sensed by the pump and pukp pump will back to hold the margin set on the compensator.
A10VSO Variable displacement pump power control It’s a power limiting pump with a load sense compensator. Part of the reason for this long discussion in the first place is that this design is a bit weird, I give you that Adrian.
Download Now White Paper: Get best deals for coconut. It is only the fact that a10cso make so many machines with this sort of control that means I can spot the difference. By joining you are opting in to receive e-mail. It would also help to know the stand by pressure of the pump Adrian.
Bosch Rexroth Axial Piston Variable Pumps Type A10VSO series 31 – Hyquip
The pump flow will of course reduce when the pump power hits the power limit curve but the pump flow is not directly controlled by the proportional relief. We have several hundred regular clients from both the public and private sectors. However the LS compensator is only being used to enable the proportional relief valve to adjust the cut-off maximum pressure.
Preference cookies enable a website to remember information that changes the way the website behaves or looks, like your preferred language or the region that you are in. The pupm setting of this pilot relief thus determines the power limit and the setting of the proportional relief sets the normal cut-off pressure.
Seriously Adrian, when EV3 is closed the pump will be trying to swivel to max as hard as it can. The proportional pressure relief valve Item 2 opens at the set pressure.
When this happens, the flow controller shifts and gives oil to the back of the yoke piston. Please find document below http: In pujp DRS control, the pumps entire flow passes through a variable orifice which creates a pressure drop.
Variable Displacement Pump A10VSO / A10VO
The A10VO is designed for mobile applications such as construction machinery. View Contact Call Seller Now.
Deactivating this cookie would stop permitting the orders. Could you give me details on this phenomenon? To see if there is a power limiting valve attached to the servo piston. Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.
My suggestion; I recently saw an old SauerDanfoss amplifier card that had an integrated power controller based on input from the electric motor current measurement. It could be puump a lot to the design. Get in Touch with us Makhoz Corporation. It features fast control response, and its through- shaft design allows it to be used in multiple hydraulic circuit systems.
