液压系统 Hydraulic system(中文5800字,英文3700字)
1绪论
液压站又称液压泵站，是独立的液压装置。
它按逐级要求供油。并控制液压油流的方向、压力和流量，适用于主机与液压装置可分离的各种液压机械上。
用户购后只要将液压站与主机上的执行机构（油缸或油马达）用油管相连，液压机械即可实现各种规定的动作和工作循环。
液压站是由泵装置、集成块或阀组合、油箱、电气盒组合而成。各部件功能为：
泵装置－－上装有电机和油泵，是液压站的动力源，将机械能转化为液压油的压力能。
集成块－－由液压阀及通道体组装而成。对液压油实行方向、压力和流量调节。
阀组合－－板式阀装在立板上，板后管连接，与集成块功能相同。
油箱－－板焊的半封闭容器，上还装有滤油网、空气滤清器等，用来储油、油的冷却及过滤。
电气盒－－分两种型式。一种设置外接引线的端子板；一种配置了全套控制电器。
液压站的工作原理：电机带动油泵转动，泵从油箱中吸油供油，将机械能转化为液压站的压力能，液压油通过集成块（或阀组合）实现了方向、压力、流量调节后经外接管路并至液压机械的油缸或油马达中，从而控制液动机方向的变换、力量的大小及速度的快慢，推动各种液压机械做功。
Hydraulic system
Chapter 1 Introduction
Hydraulic Pump Station also known as the stations are independent h- ydraulic device.
It requested by the oil gradually. And controlling the hydraulic oil flow direction, pressure and flow rate, applied to the mainframe and hy- draulic devices separability of hydraulic machinery.
Users will be provided after the purchase hydraulic station and host of implementing agencies (motor oil or fuel tanks) connected with tubing, Hydraulic machinery can be realized from these movements and the work cycle.
Hydraulic pump station is installed, Manifold or valve combination, t- anks, a combination of electrical boxes.
Functional components :
Pump device -- is equipped with motors and pumps, hydraulic station is the source of power. to mechanical energy into hydraulic oil pressure can be.
Manifold -- from hydraulic valve body and channel assembled. Right direction for implementation of hydraulic oil, pressure and flow control.
Valve portfolio -- plate valve is installed in up board after board conn-
ects with the same functional IC.
Tank -- plate welding semi-closed containers, also loaded with oil filtering network, air filters, used oil, oil filters and cooling.
Electrical boxes -- at the two patterns. A set of external fuse terminal plate; distribution of a full range of electrical control.
Hydraulic Station principle : motor driven pump rotation, which pump oil absorption from the oil tank. to mechanical energy into hydraulic pressure to the station, hydraulic oil through Manifold (or valve combinations) realized the direction, pressure, After adjusting flow pipe and external to the cylinder hydraulic machinery or motor oil, so as to control the direction of the motive fluid transformation force the size and speed the pace of promoting the various acting hydraulic machinery. |
