The composition and working principle of hydraulic station: hydraulic station, also known as pump stations, independent hydraulics, oil supply (host) drive requirements, and control the direction of oil flow, pressure and flow , it applies to the host and hydraulics separable variety of hydraulic machinery. User after purchase as long as the implementing agencies (the fuel tank and motor oil) on the hydraulic station and the host tubing connected to the hydraulic machinery to the action of the various provisions, the duty cycle. The hydraulic station is made by the pump device, a combination of the manifold or the valve, fuel tank, electrical box combination. The various components function as follows: pump unit - is equipped with a motor and pump, hydraulic station power source, the mechanical energy into power for the hydraulic oil can. Manifold - is a combination of hydraulic componentshydraulic valves and channel body. Its hydraulic oil to implement the direction, pressure, flow regulator. Valve combination - plate valve installed in the stand-board, board after the pipe connection, the same as the Manifold function. - Fuel t ank semi-closed container is a welded steel plate, is also equipped with oil filter network, air filter, which is used oil storage, oil cooling and filtering. Electric Box - points in two forms. A setting external lead terminal board; one is the installation of full control of electrical appliances. Hydraulic station works as follows: motor driven oil pump rotary pump from the pump after oil absorption Dayou convert mechanical energy to the pressure of the hydraulic oil, hydraulic oil through the manifold block (or valve combination) hydraulic valve to achieve the direction, pressure, flow adjusted by the external pipeline transmission to hydraulic machinery, fuel tanks or motor oil to control the direction of the transformation of the fluid motive force size and speed of, and promote a variety of hydraulic mechanical work. Second, the structure in the form of hydraulic pipe fittingshydraulic station and main technical parameters: the structure of the hydraulic station, the pump device structure, the installation location and cooling method to distinguish between the institutional forms of the pump device installation location can be divided into three kinds: 1, set Vertical: pump device vertical installation on the tank cover, mainly for the quantitative pump system, an ideological, horizontal on the home: the pump device horizontally mounted on the tank cover, mainly for the variable pump system, in order to facilitate the flow regulation. 3, next to the mounted: pump device horizontal installed in the tank next to a separate on the basis of the next-mounted equipment, spare pump is mainly used for fuel tank capacity 250 liters, more than 7.5 kilowatts of electrical power systems. Station cooling method can be divided into two types: a natural cooling: air heat exchanger cooled by the fuel tank itself, generally used for the system, an ideological fuel tank capacity of le ss than 250 liters. 2, forced cooling: to take the cooler forced cooling system generally used for fuel tank capacity greater than 250 liters. The hydraulic station to the effective storage of the fuel tank of fuel and electrical power of the main technical parameters. Tank capacity of 18 kinds of specifications (unit: liters / L): 25,40,63,100,160,250,400,630,800,1000,1250,1600,2000,2500,3200, 4000,5000,6000 this series hydraulic conditions of use according to user requirements and in accordance with conditions, you can do: System Configuration Manifold or not with Manifold. 3 can be set to the electrical control devices can be set cooler, heater, accumulator, or not with the electrical controlshydraulic bolt
