Before discussing the exact values of the pressure from the Cat excavator to the large pump, it needs to be made clear that different models of Cat excavators may have different standard pump pressures.Normally, the major pump pressure adjustment of the Cat excavator needs to be precisely set by a professional maintenance technician based on the design specifications and actual working requirements of the hydraulic system.For example, in the case of Cat320D excavators, the main pump pressure is generally set at about 350 bar, but may need to be moved to higher levels to meet larger excavator requirements under specific construction conditions.However, it is not wise to increase pump pressure blindly, and excessive pump pressure can cause hydraulic system failure and even affect the overall performance and useful life of excavators.The guidelines in the operating manual and the use of professional tools and techniques are to be followed when large-pump pressure is adjusted.Cat excavator users are advised to consult directly with official after-sales services or qualified maintenance service providers to obtain accurate information if they need to know the reasonable range of pump pressure of a specific type of aircraft.In summary, the Cat excavator's major pump pressure is a process involving multiple considerations of specific models, working conditions and safety factors to ensure that equipment performance is optimized without compromising its inherent stability and durability.Emphasis on keywords: Cat excavator, large pump pressure, calibration, model, hydraulic system, maintenance services.
