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

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。 (责任编辑：qin)
