Abstract
The utility model relates to a two-inclined plate large flow plunger type oil pump, which belongs to a hydraulic pressure plunger type oil pump. The diameter in the middle of a casing body is provided with an oil inlet and an oil outlet, and the inner wall in the middle of the casing body is provided with two half-ring grooves respectively communicated with the oil inlet and the oil outlet. The left end and the right end of a casing body cavity are respectively fixed with an inclined disc, and each inclined disc is respectively attached with a sliding shoe. Each sliding shoe is uniformly hinged with seven plungers in the circumferential direction, and a cylinder body fixed in the middle part of a main shaft is uniformly distributed with seven axial plunger holes. The middle part of the cylinder body is uniformly distributed with seven radical holes communicated with the seven plunger holes. Main shafts on both sides of the cylinder body are respectively sheathed with a ball pivot cover. The oil pump has the advantages of small volume and high oil discharge quantity.
Description
The utility model belongs to hydraulic plunger oil pump class.
Existing plunger-type fuel pump, be the monocline disc type, as the ZBD profile shaft to plunger pump, its structure is to have to have on housing, the housing in turnover oilhole, the housing main shaft is arranged, there is a swash plate on the right side of housing cavity, by investing the crawler shoe on the swash plate, circumferentially even 7 plungers of ball pivot of crawler shoe, 7 plungers are inserted in respectively in 7 holes of cylinder body, and cylinder body props up by the ball pivot cover and withstands on the crawler shoe.When main shaft rotated, cylinder body drove plunger and crawler shoe rotates together, under the effect of swash plate, made that plunger is reciprocating to carry out oil suction and oil extraction, and oil sucks and discharges through the left side of housing cavity oil distribution casing.The deficiency of the plunger-type fuel pump of this monocline disc type is: volume is big, flow is little, efficient is low.
The purpose of this utility model is: provide that a kind of volume is little, flow is big, efficient is high, the big flow plunger-type fuel pump of diclinic dish.
Technical measures of the present utility model are: on the diameter at housing middle part an oil inlet hole and an oil outlet are arranged, on the inwall of housing middle part two half circle groove that communicate with oil inlet hole and oil outlet are respectively arranged; Fix a swash plate respectively at the two ends, the left and right sides of housing cavity; Lean on an attached crawler shoe on each swash plate respectively, circumferentially even 7 plungers of ball pivot of each crawler shoe; The cylinder body that is fixed on the main shaft middle part circumferentially is evenly equipped with 7 axial plunger holes; The middle part of cylinder body circumferentially is evenly equipped with 7 radial holes that communicate with plunger hole; On the main shaft of cylinder body both sides, be with a ball pivot cover respectively.
The big flow plunger-type fuel pump of diclinic dish of the present utility model, owing to adopt the structural type of diclinic dish, 7 pairs of plungers, so oil pump has the good effect that volume is little, flow is big, efficient is high.
Fig. 1 is a structural representation of the present utility model.
Among the figure 1 and 9 be swash plate, about each one, be separately fixed at the two ends of housing 2; On the diameter at the middle part of housing 2, an oil inlet hole A and oil outlet B are arranged respectively, two half circle groove 6 and 13 that link with oil inlet hole A and oil outlet B are respectively arranged on housing 2 middle part inwalls, it 6 is oil-feed half circle groove, and 13 are the oil extraction half circle groove, and two annular grooves do not communicate.On each swash plate 1, lean on an attached crawler shoe 3 and 8 respectively, circumferentially even 7 plungers 4 of ball pivot of each crawler shoe, the cylinder body 5 that is fixed on main shaft 10 middle parts circumferentially is evenly equipped with 7 axial columns consents, be inserted with two plungers 4 and 7 in each hole respectively, the middle part of cylinder body 5 circumferentially is evenly equipped with 7 warp-wise holes 12 that communicate with plunger hole, is with a ball pivot cover 11 and 14 on the main shaft 10 of cylinder body 5 both sides respectively.When main shaft 10 and cylinder body 5 rotated, two crawler shoes 3 and 9 and 14 plungers 4 and 7 rotated simultaneously, and plunger also moves axially simultaneously, a half cycle oil suction, in another half cycle oil extraction.Can be processed with annular groove as hydrostatic bearing at housing 2 inwalls and cylinder body 5 outer rims, increase the stability of cylinder body 5.
Claims (1)
1, the big flow plunger-type fuel pump of a kind of diclinic dish is made up of housing, main shaft, swash plate, crawler shoe, plunger; Be characterized in:
A, on the diameter at housing middle part, an oil inlet hole and an oil outlet are arranged, on the inwall of housing middle part, two half circle groove that communicate with oil inlet hole and oil outlet are respectively arranged;
