课程名称：Garnett Cross高级液压培训 课程概述：本课程将为您提供设计液压系统、延长其正常运行时间和寿命所需的基本资源。内容基于多年实践现场经验和咨询指导。您将通过详细的20步方法指导，设计一个完整的液压系统，包括缸径、缸壁厚度、杆径、泵流量、管道直径、驱动系统的千瓦/电流和减压要求。此外，课程还将教您如何解决液压系统中的各种复杂问题。课程中提供了详细的动画，以帮助理解液压油的流动及各个组件和系统的操作。 课程内容涵盖： - 各种类型的阀门及其在液压系统中的应用，如： cartridge阀、止回阀、先导止回阀、卸载阀、流量控制阀、过中心阀、溢流阀、方向控制阀。 - 油过滤，液压过滤器的设计和选择。 - 常常被忽视的液压系统关键因素。 - 液压缸的设计、缸的公差和缓冲设计。 - 储液池设计。 - 油的压缩与减压回路。 - 液压系统中的压力强化及保护系统方法。 系统设计模块包括： - 并联和串联操作缸。 - 循环油系统。 - 双泵系统。 - 再生系统。 - 快速接近、缓慢施压系统。 - 液压驱动，包括闭环和开环系统的电机选择。 您将学习到必要的公式，并通过详细示例来确定： - 移动缸所需的压力和给定负载。 - 缸的选择、杆径和缸壁厚度。 - 流量计算。 - 缸盖端所需的螺栓数量。 - 所需的泵流量和回流流量。 - 驱动泵所需的功率。 - 液压软管选择、吸入管直径、压力管直径和回流管直径。 - 压力强化。 - 过滤器尺寸 - 压力和回流管。 - 阀门尺寸。 - 油的压缩及减压系统的要求。 - 储液池大小。 - 缓冲器选择。 - 液压驱动电机选择。 注意：尽管本课程所教授的原理一般适用，但所示材料和计算是基于特定参数，缸的制造材料、油的粘度或成分以及当地条件都必须在设计系统时纳入计算。由于涉及到生命和财产的潜在危险，设计必须由专业机械工程师进行审核。
This course will provide you with the essential resources to design and extend the up-time and life of hydraulic systems. Content draws on years of practical field experience and consulting.You will be guided through a detailed 20 step approach to design a complete system including cylinder diameter, cylinder wall thickness, rod diameter, pump flow rate, pipe diameters, kW / amperage to drive the system and decompression requirements.In addition to overall system design, you will be instructed in how to solve challenging problems in hydraulic systems.Detailed animations are provided to help understand the flow of oil and operations of the various components and systems.Materials covered:- Various types valves and their use within a hydraulic system. (Cartridge valves, Check Valves, Pilot Operated Check Valves, Unload Valves, Flow Control Valves, Over Center Valves, Relief Valves, Directional Control Valves).- Oil Filtration, design and selection of hydraulic filters.- Often overlooked critical factors of a hydraulic system. - Design of hydraulic cylinders, cylinder tolerances and cushioning.- Reservoir Design.- Oil Compression and de-compression circuits.- Pressure Intensification within a hydraulic system and how to protect a system.- Systems: - Operating cylinders in parallel and series. - Circulating oil. - Double pump system. - Regenerating system. - Fast Approach, slow press system. - Hydrostatic drives, closed and open loop systems including motor selection.You will be provided the necessary formulae with detailed examples to determine:- Pressure required to move a cylinder for a given load.- Cylinder selection, rod diameter and cylinder wall thickness.- Flow rates.- Number cap screws required for cylinder cap end.- Required pump flow rate and return line flow rate.- Power requirements to drive the pump.- Hydraulic hose selection, suction line diameter, pressure line diameter, return line diameter.- Pressure intensification.- Filter sizing - pressure and return line.- Valve sizing.- Compression of oil and requirements for a decompression system.- Reservoir sizing.- Accumulator selection.- Hydrostatic drive motor selection.Note: Although the principles taught in this course are generally applicable, the material and calculations are demonstrated for a given set of parameters, the materials used for cylinder manufacture, oil viscosity or composition and local conditions must all be factored in to the calculations when designing a system. A professional mechanical engineer must review designs due to potential danger to lives and property.
