Description
Technical field
The invention belongs to loader hydraulic system hydraulic efficiency oil (liquid) field, particularly load sensing plunger variable pump hydraulic work system oil compositions.
Background technology
Load sensing plunger variable pump hydraulic system is the state-of-the-art system of technology in the hydraulic efficiency system of using on current shovel loader, and its major advantage is energy-saving and cost-reducing, and environmental protection meets the development trend of modern hydraulic technology completely.Aspect hydraulic efficiency system, no matter be quantitative gear list pump hydraulic system or many pumps combination hydraulic system, all can not cause the capacity usage ratio of system lower according to the output of load request timely adjustment flow, working temperature is high, needs larger scatterer; Also there is lower, the problem such as oil consumption is high of Hydraulic Elements life-span simultaneously.Hydraulic efficiency system is about 40%～60% in shovel loader energy consumption accounting, and the pump of quantitative system cannot carry out according to loading demand the adjusting of output flow.Therefore its energy consumption is compared the gap that has 10～40% with variable system.Load sensing plunger variable pump hydraulic system can be by the signal feedback of hydraulic system of working and steering hydraulic system to variable volume pump, and variable volume pump regulates working order thus, and then the anti-desired pressure of system and the flow of providing is to reach energy-conservation object.Because this system can regulate working order completely voluntarily, the required flow of equipment and pressure are only provided, just energy loss can be dropped to minimum.This system belongs to " green product ", meets future developing trend, but its complex structure.In order to be in use strictly on guard against that emptying phenomenon appears in plunger variable pump, must strictly control oil cleanliness.More than system requirements degree of cleaning are controlled in NAS8 level, to guarantee the work-ing life of element; Otherwise, very easily cause card valve plug-hole, cause the damage of pump.Therefore, the characteristic that this system works oil (liquid) is required to have except common antiwear hydraulic oil, also require good viscosity index, filterableness, dispersiveness, detergency, high resistance shear stability, thermal oxidation stability, air release value, low-temperature fluidity and water resisting property etc.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of except having the characteristic that common antiwear hydraulic oil has, and also has the load sensing plunger variable pump hydraulic work system oil compositions of good viscosity index, filterableness, dispersiveness, detergency, high resistance shear stability, thermal oxidation stability, air release value, low-temperature fluidity and water resisting property.
The present invention adopts following technical scheme to solve the problems of the technologies described above:
