How it works: the piston moves from left to right, form a negative pressure pump cylinder, then the suction tank fluid through the valve into the pump 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。
Full use of its bearing capacity of the tank to reduce the oil vapor emissions, the principle is to use the weight of the valve plate to control the breath pressure and suction tank negative pressure.
充分利用油罐本身的承压能力来减少油蒸气排放,其原理是利用阀盘的重量来控制油罐的呼气正压和吸气负压。
Open system is the pump suction from the tank, the oil through a variety of control valves, the drive hydraulic actuators, valve oil return back for another fuel tank.
开式系统是指液压泵从油箱吸油,油经各种控制阀后,驱动液压执行元件,回油再经过换向阀回油箱。
