Abstract
The utility model relates to an energy-saving type displacement pump, wherein a middle spacer block is arranged in the pump body, two side surfaces of the pump body are provided with pump body bushings bilaterally symmetrical to each other, a chute is made at the upper end of the middle spacer block, a pump cavity sliding block is arranged in the chute, left-end and right-end curved cams are arranged in the pump body bushings, a pump shaft penetrates through the left-end and right-end curved cams, the pump shaft is provided with a flat key which is connected with the left-end and right-end curved cams, and left and right pump covers are arranged on two side surfaces of the pump body. As the curved cams are arranged to drive the pump cavity sliding block to conduct medium charging-discharging operation, parts participating in movement are less, mechanical loss is low, the mechanical efficiency of the pump is high, leakage points of the pump are less, and the volumetric efficiency of the pump is high.
Description
Technical field
The utility model relates to a kind of liquid transporting apparatus, relates to the energy-conservation displacement pump device of a kind of dish-type end face curved surface cam specifically.
Background technique
At present, known existing liquid transporting apparatus kind is a lot, and displacement pump is exactly a major types wherein.As gear pump, vane pump, screw pump etc., their efficient is low, power consumption is big.Innovative development high efficiency energy saving pump product is the important topic of pump industry from now on.
Summary of the invention
At low, the big problem that consumes energy of efficient that existing displacement pump exists, the utility model provides a kind of efficient height, the low energy-saving displacement pump device of power consumption.
Solving the problems of the technologies described above the concrete technological scheme that is adopted is: a kind of energy-saving displacement pump, it is characterized in that: in the inside center position of the pump housing (3), middle spacer block (6) is housed, symmetrical pump housing lining (9) is equipped with in its bi-side, the upper end of middle spacer block (6) and pump housing lining (9), be shaped on chute, the chute mouth (11) of chute upper end is imported and exported with the pump housing (3) and is communicated, pump chamber slide block (5) is contained in the chute, left end curved surface cam (4) is contained in the left pump housing lining (9), right-hand member curved surface cam (8) is contained in the right pump housing lining (9), left end curved surface cam (4) becomes 180 degree opposed with the male and fomale(M﹠F) of right-hand member curved surface cam (8), pump shaft (1) therefrom passes, a flat key and a left side are housed on the pump shaft (1), right-hand member curved surface cam links to each other, at the pump housing (3) left surface left pump cover (2) is housed, right pump cover (10) is housed at the pump housing (3) right flank.
The beneficial effects of the utility model: carry out medium and advance to arrange operation because curved surface cam driven pump chamber slide block is housed, it is few therefore to participate in moving parts, and mechanical loss is little, the mechanical efficiency height of pump, and the leak point of pump is few, the volumetric efficiency height of pump.

Embodiment
Be described with reference to the accompanying drawings structure of the present utility model.
A kind of energy-saving displacement pump, as depicted in figs. 1 and 2: in the interior central position of the pump housing 3, spacer block 6 in being equipped with, symmetrical pump housing lining 9 is equipped with in its bi-side, the upper end of middle spacer block 6 and pump housing lining 9, be shaped on chute, the chute mouth 11 of chute upper end is imported and exported with the pump housing 3 and is communicated, and pump chamber slide block 5 is contained in the chute.Left end curved surface cam 4 is contained in the left pump housing lining 9, and right-hand member curved surface cam 8 is contained in the right pump housing lining 9, and left end curved surface cam 4 becomes 180 degree opposed with the male and fomale(M﹠F) of right-hand member curved surface cam 8.The curved-surface structure of curved surface cam, as shown in Figure 3, Y-axis is a lift, high K; X-axis is the central angle angle value, and A is Pinggu to B, and B is a circular arc to C, its knuckle radius R and tortuous the relation that goes up the central diameter d of loca: R=0.45d; C is a sinusoidal curve to D, functional equation: Y=21.5+21.5 * sin (X-90 °); D is a circular arc to E, its knuckle radius and tortuous the relation that goes up the central diameter d of loca: R=0.45d; B is flat peak to F; Shape line bilateral symmetry, symmetry axis were 180 ° of vertical axis by flat peak center.Pump shaft 1 therefrom passes, and flat key is housed on the pump shaft 1 links to each other with left and right end curved surface cam, at the pump housing 3 left surfaces left pump cover 2 is housed, and at the pump housing 3 right flanks right pump cover 10 is housed.
Two end faces of pump chamber slide block 5 contact with the cam curved surface of left and right end curved surface cam constantly, the convex surface of two curved surface cams closely contacts with the sagittal plane of the left and right pump housing lining 9 of pump constantly, and the face of these four contacts is divided into two pump chambers in every limit with pump housing lining 9 spaces, the left and right sides.When the rotation of the left and right end curved surface cam of driven by motor, two pump chambers on every limit, one become big, one diminish.Become the pump chamber that big pump chamber begins to suck medium, diminish and begin to get rid of medium, whenever circle and finish into and two operations of row.
