Working principle: piston moves from left to right, form a negative pressure pump cylinder, the liquid tank into the pump by the inhalation valve cylinder.
工作原理：活塞自左向右移动时，泵缸内形成负压，则贮槽内液体经吸入阀进入泵缸内。
What is a hydraulic press?The hydraulic press is by the high-pressured liquid (oil, emulsion and so on) transmits the working pressure the forging and stamping machinery.
什么是液压机?液压机是以高压液体（油、乳化液等）传送工作压力的锻压机械。
Liquid system is the need for oil pressure, flow, direction control and regulation to meet the needs of working parts in the power, speed and direction requirements.
液正系统工作，必须对油液压力、流量、方向进行控制与调节，以满足工作部件在力、速度和方向上的要求。
The pressure regulation valve, working without exterior energy, has the functions of pressure regulating, overflow closing, liquid temperature expansion relieving, and set pressure opening.
该阀不依赖外部能源工作，具有自动节流减压、泄漏超流自动截断、禁开、温升膨胀自动卸压和压力自动开启等多项功能。
The high pressure liquid in the accumulator (with potential energy) enters the working cylinder in a flash and the potential energy converts to kinetic energy.
蓄势器内的高压液体(具有势能)进入工作缸是在瞬时之间进行的，具有势能转变为动能作功的特点。
Accumulator is used in hydraulic press driven by pump-accumulator. The high pressure pump with small flow can put working liquid into the accumulator in the intermittent working time of press.
泵-蓄势器传动的液压机，由于采用了蓄势器，故只用流量较小的高压泵。
