Piston pump outlet valve is opened, the liquid discharge. When the cylinder drive shaft rotates, the swash plate plunger is pulled out or pushed back from the cylinder radial piston hydraulic Minhang, complete oil suction process. A reciprocating pump working cavity of the plunger and the cylinder bore formed below the volume of a pump plunger driven by the pump shaft eccentrically rotates, the reciprocating movement, its suction and discharge valves are a check valve. When the plunger is pulled outside the working chamber pressure is reduced, the outlet valve is closed, lower than the inlet pressure, the inlet valve is opened, the liquid enters; when you push in the plunger chamber pressure increases, the inlet valve closed Minhang hydraulic radial piston pump , higher than the outlet pressure of the fluid through the valve plate are suction pump and drain cavity. Variable mechanism for changing the swash plate angle by adjusting the swash plate angle can change the pump displacement. High pressure piston pump characteristic instantaneous flow is pulsating, it is because in piston pump, the suction and discharge process of the liquid medium is alternately Minhang hydraulic radial piston pump and piston displacement process, its speed again constantly changing. Only one pump working chamber, the instantaneous flow pump not only change over time, and is not continuous. With the increase in the working chamber, instantaneous flow pulsation amplitude smaller and smaller, and even can be considered practically turbulence. Hydraulic radial piston pump _ _ Lu Minhang radial piston hydraulic force provided by the Texas Lu of the hydraulic machinery plant. Texas Lu force hydraulic machinery plant (www.luliyeya.com) is an industry leader in Shandong Dezhou, hydraulic machinery and parts, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Lu Hydraulic leadership with the staff warmly welcome all inquiries negotiations to create Lu Hydraulic better future.
