The plunger up oil, when the uplink to the chute (stop for the edge) on the plunger back hole on the sleeve and connected, then low pressure oil pump oil chamber and the head of the plunger hole and radial holes and chutes communication, a sudden drop in oil pressure, three-row radial piston pump, delivery valve quickly closed to stop the oil under the action of the spring force. Thereafter the plunger but also upstream, Henan radial piston pump, when the raised portion of the cam turn in the past, under the action of the spring plunger and down. At this time began the next cycle. Piston pump with a plunger to introduce the principle, a two-way valve on the piston, and in the opposite direction, a negative pressure occurs when the cylinder piston movement in one direction, then the one-way valve opens the liquid is sucked After the cylinder, the plunger movement in the other direction, the other liquid compression check valve is opened, liquid is sucked into the cylinder is discharged. This way of working in continuous motion after the formation of a continuous supply. The pump shaft with a stream radial piston pump, the pump has a stator and a rotor, the two eccentric arrangement of the rotor shaft mounted on assignment, opened in the circumferential direction of the rotor with seven uniform plunger hole, the plunger may be wherein the flexible movement. * When the shaft to drive the rotor rotates, due to the return of the ring and connecting rod, double radial piston pump, the rotor bore, the plunger reciprocates, to achieve change seal volume. Each revolution of the rotor, radial piston find Lu force, each plunger reciprocates once, to complete a suction and discharge of oil. Hydraulic oil from the pump suction port with flow axis through internal channels, into the plunger cavity in the rotor to later this week, when the rotor to boost half weeks later, half of the shaft from a high pressure with flow discharged through the drain port area, supply actuators. * On both sides of the pump body with large and small control piston pressure pump oil through the oil passages on the way into the small control piston, the other way through the variable mechanism (valve) produce a voltage drop, and then enter the big control piston cavity. When the pump by adjusting the variable control mechanism, so that the size of the control piston movement of the stator in the horizontal direction, to change the size of eccentricity, so as to achieve the purpose of the variable. Double radial piston pump radial piston pump _ _ Henan Lu Lu of hydraulic force provided by the hydraulic machinery plant in Texas. Texas Lu force hydraulic machinery plant (www.luliyeya.com) strong, credible, in Dezhou hydraulic machinery and components industry has accumulated a large number of loyal customers.
