外文资料翻译 Hydraulic Station and the development of hydraulic components Profiles ABSTRACT Hydraulic Pump Station also known as the stations are independent hydraulic device. It requested by the oil gradually. And controlling the hydraulic oil flow direction, pressure and flow rate, applied to the mainframe and hydraulic devices spearability 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, tanks, 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. A development course China Hydraulic (including hydraulic, the same below), pneumatic and seals industrial devel
