Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, embodiment, structure, feature and effect thereof that foundation the utility model is provided, describe in detail as after.
The novel pump housing of a kind of radial plunger pump shown in Fig. 1～4 comprises pump cover 1, the pump housing 2, valve body 3, spool 4, plunger 5, size control plunger 6,7, big small slide block 8,9, connecting rod 10, stator 11, rotor 12, transmission shaft 13, pintle 14, shaft coupling 15 and backhaul ring 16; Pump cover 1 is connected with the pump housing 2 usefulness screws 20, spool 4 is packed in the center hole of valve body 3, size control plunger 6,7 is contained in respectively in the big or small plunger hole of the pump housing 2 and with big small slide block 8,9 spheres and joins, another cambered surface and the stator of big small slide block 8,9 join, plunger 5 links to each other with connecting rod 10 and packs in the plunger hole of rotor 12, connecting rod 10 outer arced surface and stator 11 form friction pair, intrados and backhaul ring 16 form friction pair, rotor 12 is contained on the pintle 14, high speed rotating under transmission shaft 13, shaft coupling 15 drive utilizes the eccentric high pressure that produces.The described pump housing 1 is made by material HT300, the center of the pump housing is equipped with a center hole 17, pintle is housed in the center hole, stator is contained in the pump housing cavity 18, large and small control plunger is contained in respectively in the large and small control plunger hole 19,20 of the pump housing, large and small slide block contacts with the sphere of large and small control plunger respectively, and the other end cambered surface of large and small slide block promotes stator; Stator is move left and right in pump housing cavity, adjusts throw of eccentric by large and small control plunger and large and small slide block, changes flow.
Working principle:
During work, hydraulic oil enters the pump housing from inlet, through the pintle flow, forms high pressure oil by plunger extruding hydraulic oil, through static balance high pressure oil is delivered to outside the pump housing in pump housing chamber, finishes the process that is converted to high pressure oil by low pressure oil.The pump housing bears high pressure oil in the chamber, and casting quality is higher.
