摘要目前,液压锚机具有良好的调速性和便捷性,因此在船舶行业中被广泛地使用,而 为液压锚机提供动力的液压泵站就显得尤为重要。液压泵站的工作原理是:电机带动油 泵旋转,泵从油泵中吸油后打油,将机械能转化为液压油的压力能,液压油通过集成块(或阀组合)液压阀实现了方向、压力、流量调节后经外接管路传输到液压机械的油缸 或油马达中,从而控制了液动机方向的变换、力量的大小及速度的快慢,推动各种液压 机械做工从而实现相应的设计要求。81552

本文在了解φ46 组合式起锚机液压泵站的设计的用途及动作流程的基础上,确定了 液压锚机各动作的实现方式。首先进行了锚机的液压系统总体设计,包括:液压原理的 设计、液压管路的设计、主要液压元器件的计算选型及具体液压泵站的设计;其次,通 过对整个锚机液压系统的进行了设计计算,分析了液压锚机的工况,对锚链轮、卷筒工 况,得出了三种工况下锚机的动力参数,在此基础上选取了马达的型号,并计算出三种 工况下所需的压力和流量,依据最大压力和流量以及所用功率选取液压泵型号和电机型 号;然后,设计了锚机的液压控制系统,实现液压锚机收锚、抛锚、以及中位停机的功 能,并且绘制液压原理图,选取系统所需要的液压元器件型号,设计液压电机控制电路 图,实现液压电机的 Y-△起动;最后,根据系统所需油量,以及选用的液压元件大小设 计油箱以及泵站的总体方案,包括管路的布置设计和液压辅助元器件(冷却器、过滤器、 温度计等)的选型,根据系统的总体设计,验算整个系统的性能参数。

Abstract At present, the hydraulic anchor machine has good speed and convenience,thus is widely used in ship industry, and power hydraulic windlass hydraulic pump station is particularly important。 Hydraulic pump station working principle is: motor drive the oil pump, pump oil from the oil pump after the preview, can convert mechanical energy into hydraulic oil pressure and hydraulic oil through the integrated block (or valve) hydraulic valve realizes the direction, pressure and flow rate adjusted by the external pipeline transmission to the oil cylinder of hydraulic machinery or oil motor, so as to control the size of the liquid motive direction transformation, power and speed of speed, drive all kinds of hydraulic machinery work so as to realize the corresponding design requirements。

Phi 46 combined windlass hydraulic pump station in understanding the purpose of the design and process of action, on the basis of determining the hydraulic windlass way of realization of each action。 First has carried on the windlass hydraulic system overall design, including: the design of the hydraulic principle, the design of the hydraulic pipeline, the main calculation and selection of hydraulic components and the concrete design of hydraulic pump station; Second, through to the windlass hydraulic system has carried on the design and calculation, analyzes the working condition of hydraulic windlass, the chain wheel, the drum operating mode, it is concluded that the three kinds of the windlass under the condition of dynamic parameters, on the basis of selecting the motor model, and calculates the required pressure and flow of three kinds of working conditions, according to the maximum pressure and flow, and the selection of hydraulic pump power model and motor model; Then, design the windlass hydraulic control system, realize the hydraulic anchor their anchor, anchor, and functions of the median downtime, and draw the hydraulic principle diagram, hydraulic components needed for model selection system, design of hydraulic motor control circuit diagrams, realize hydraulic motor Y - delta starting; Finally, according to the required oil system, as well as the selection of hydraulic components size to design the overall scheme of the fuel tank and pump station, including the piping layout design and hydraulic auxiliary components (cooler, filter, thermometer, etc。) of selection, according to the overall design of the system, check the performance of the whole system parameters。
