Abstract
The utility model discloses a three-cam shaft for a high-flow high-pressure constant-flow pump, which is provided with a shaft (1), and is characterized in that three cams (2) with the same curves are fixed on the shaft (1), the differences of the angles of the three cams (2) are sequentially 120 degrees, the lift angle of each cam is 240 degrees, the return angle is 120 degree, and the lift is 13mm. The cam shaft continuously rotates, and two cams are always maintained in the lift state, one cam is always in the return state, the overlaid data of the two cams in the lift state uniformly rises, and a compensation area is increased at the alternative angle area among the cams to counteract the transmitted liquid fluctuation caused by the alternation of the cams, and the property is stable. In the utility model, a pump head can output liquid simultaneously through two plunger rods, the problems that the requirement to the rotating speed of a motor is high, the diameter of a plunger is required to be large, the processing is difficult, and the like can be solved, the processing is simple, and the manufacture cost can be reduced.
Description
Technical field:
The utility model relates to a kind of constant flow pump camshaft, big-flow high-pressure constant flow pump three camshafts of especially a kind of simple in structure, easy processing, with low cost, reliable performance.
Background technique:
High pressure constant flow pump has stability of flow, advantage that pressure is high, at present widely used is twin cam shaft pump in parallel, be to be fixed with two cams that curve is identical on the line shaft, two cam angle degrees differ 180 °, and the lift angle of each cam, backhaul angle are 180 °.The driven by motor twin cam shaft rotates during work, the rotation potential energy of each cam is changed into straight line motion kinetic energy, thereby drive two plunger rods motions of pump head respectively, finishes the high voltage and constant current infusion process.But, when flow reaches certain numerical value, certainly will require the liquid output speed of single plunger to increase substantially, can only realize by the mode that increases motor speed or increase plunger rod diameter, cause choice of electrical machine difficulty, cost height and plunger rod processing difficulties etc.
Summary of the invention:
The utility model is in order to solve the above-mentioned technical problem of existing in prior technology, and big-flow high-pressure constant flow pump three camshafts of a kind of simple in structure, easy processing, with low cost, reliable performance are provided.
Technical solution of the present utility model is: a kind of big-flow high-pressure constant flow pump three camshafts, axle 1 is arranged, it is characterized in that: on axle 1, be fixed with three cams 2 that curve is identical, three cam 2 angles differ 120 ° successively, 240 ° of the lift angles of each cam, 120 ° of backhaul angles, lift 13mm.
Parallel connection three camshafts that the utility model adopted, camshaft continues rotation, all the time guarantee that two cams are in the lift state, a cam is in the backhaul state, the two cam superposition of data that guarantee lift evenly raise and the alternately angular regions increase compensatory zone between cam, offset the conveying liquid fluctuation that cam alternately causes, stable performance; Can make pump head that two plunger rod output liquids are arranged simultaneously, solve problems such as, difficult processing big to motor speed requirement height, plunger diameter requirement, processing is simple, can reduce manufacture cost.
Description of drawings:
Fig. 1 is the utility model embodiment's a structural representation.
Fig. 2 is the side view of Fig. 1.
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1, 2: axle 1 same as the prior art is arranged, on axle 1, be fixed with three identical 2, three cam 2 angles of cam of curve and differ 120 ° successively, 240 ° of the lift angles of each cam, 120 ° of backhaul angles, lift 13mm.
Three cam curves such as following table, D1, D2, D3 are the diameter of three cams of same angle in the table, each null circle slips over and crosses connection.
