Total stroke reciprocating plunger piston L is constant, the decision by the cam lift. The amount of oil per cycle depends on the size of the piston stroke oil, high pressure radial piston pump, fuel trip from camshaft control is variable. Oil supply start time does not change with the stroke change. Rotation of the plunger end time can change the oil, thereby changing the amount of oil. When the piston pump work, under the action of the cam and the plunger spring in the fuel injection pump camshaft, content radial piston pump, forcing the plunger for the upper and lower reciprocating motion, thus completing the task of pumping, pumping process can be divided into for the following three stages. 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, the plunger protrudes outward in the upper half weeks, the bottom of the sealed volume increases, a partial vacuum, look for Lu of the radial piston pump, then through the dispensing axis The suction chamber 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, double radial piston pump, the structure is more complex, with the oil being radial shaft unbalance fluid pressure acts, easy to wear, which limits increase its speed and pressure. Thus, the current application is running out, gradually replaced by an axial piston pump. rg _ Lu Hydraulic radial piston pump (Online) _ content provided by the Texas Lu radial piston hydraulic equipment factory.
