High pressure piston pump characteristic instantaneous flow is pulsating, it is because in piston pump, the suction and discharge of the liquid medium is alternately process, and piston displacement process, its speed and 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, rk series radial piston pump, instantaneous flow pulsation amplitude smaller and smaller, and even can be considered practically turbulence. Radial piston pump works with the rotor bushing tight hole rotates along with the rotor, and oil distribution shaft is not moving. Radial holes in the rotor mounted around the plunger can move freely. When the rotor is rotated clockwise, the plunger protrudes by centrifugal force or under the influence of low pressure oil is pressed against the inner surface of the stator. Because eccentricity e between the stator and the rotor, Texas Lu of the radial piston pump plunger extending outwardly in the first half weeks, Maoming radial piston pump, seal the bottom of the volume increases, a partial vacuum , then with the oil suction through the cavity axis b. When the plunger later this week, at the bottom of its sealed volume decreases, the c-axis with oil by the oil discharge chamber. Each revolution of the rotor, each plunger suction and pressure oil each time. The stator can move to change the amount of eccentricity e, the pump delivery rate is also changed. Radial piston radial dimension large, Shandong Dezhou radial piston pump, the structure is more complex, the role of oil distribution shaft by radial hydraulic pressure imbalance, easy to wear, which limits increase its speed and pressure. Thus, the current application is running out, gradually replaced by an axial piston pump. Hydraulic Lu (Figure) _ Texas _ Maoming Lu of the radial piston pump radial piston pump is provided by the Texas Lu of the hydraulic machinery plant. Texas Lu force hydraulic machinery plant (www.luliyeya.com) located in Dezhou City, Shandong Province, seven West Industrial Park. Scraps and development in the wave of market economy, the current Lu hydraulic force has a high profile in the hydraulic machinery and parts, and enjoy a good reputation. Hydraulic Lu made the whole network business alliance certification, marking our service and management level has reached a new height. Lu Hydraulic staff willing to work with all people of insight and common development, for a better future.
