Description of drawings
Fig. 1 is the structural representation of a kind of high pressure super-flow injector of the present invention.
The specific embodiment
As shown in Figure 1, a kind of high pressure super-flow injector of the present invention, comprise frame 1, be positioned at major ingredient pump 3, the first auxiliary material pump 4 and the second auxiliary material pump 5 on the frame 1, the top of described major ingredient pump 3 and the first auxiliary material pump 4 is provided with auxiliary material ratio regulating system 9, and described auxiliary material ratio regulating system 9 tops are provided with hydraulic power system 2; Described frame 1 is hinged with small scale regulating arm 6, the free end of described small scale regulating arm 6 and auxiliary material ratio regulating system 9 are hinged, described small scale regulating arm 6 is provided with pump shaft connector 7, described pump shaft connector 7 links to each other with the pump shaft of the second auxiliary material pump 5, and described pump shaft connector 7 can slide at small scale regulating arm 6; The below of described major ingredient pump 3, the first auxiliary material pump 4 and the second auxiliary material pump 5 is respectively equipped with the opposite check valve of both direction 8.
Be provided with a main pump shaft 11 and a plurality of little pump shaft 10 in described the first auxiliary material pump 4.The sectional area of the main pump shaft 11 of described the first auxiliary material pump 4 be major ingredient pump 3 main pump shaft 12 95%.The sectional area of described little pump shaft 10 be major ingredient pump 3 main pump shaft 12 1%.
The operation principle of a kind of high pressure super-flow injector of the present invention is as follows:
Hydraulic power system 2 beginning rectilinear motion work, and then drive auxiliary material ratio regulating system 9 is moved, when auxiliary material ratio regulating system 9 contact wherein during the reversing switch of an end, thereupon counter motion of hydraulic power system 2, so repeatedly carry out, under the drive of this motion process, be positioned at the major ingredient pump 3 of auxiliary material ratio regulating system 9 other ends, the first auxiliary material pump 4 or the second auxiliary material pump 5 are namely started working, the proportioning of dual component material can be worked under two kinds of patterns by auxiliary material ratio regulating system 9, a. when the needs auxiliary material needs vast scale output (accounting for 95%～105%), maximum stream flow is that the first auxiliary material pump 4 of 0.95～1.05L/s links to each other with auxiliary material ratio regulating system 9, maximum stream flow is that the second auxiliary material pump 5 of 0.1L/s is connected with 9 disengagings of auxiliary material ratio regulating system, and hydraulic power system 2 links to each other with ratio regulating system 9 at the A point simultaneously; B. when the needs auxiliary material needs small scale output (accounting for 4%～6%), maximum stream flow is that the second auxiliary material pump 5 of 0.1L/s links to each other with auxiliary material ratio regulating system 9, maximum stream flow is that the first auxiliary material pump 4 of 0.95～1.05L/s is connected with 9 disengagings of auxiliary material ratio regulating system, and hydraulic cylinder 2 links to each other with ratio regulating system 9 at the B point simultaneously.Under a pattern, the adjusting of auxiliary material ratio is regulated by effective use amount of regulating the little pump shaft 10 in the first auxiliary material pump 4, the sectional area of each little pump shaft 10 is 1% of major ingredient pump 3 pump shafts, the sectional area of the first auxiliary material pump 4 main pump shaft 11 is 95% of major ingredient pump 3 pump shafts, when effective working quantity of the first auxiliary material pump 4 medium and small pump shafts 10 was adjusted between 0～10, the auxiliary material ratio can be regulated between 95%～105%; Under the b pattern, the adjusting of auxiliary material ratio realizes that by the active position of pump shaft connector 7 on small scale regulating arm 6 of adjusting the second auxiliary material pump 5 the closer to the B point, the auxiliary material ratio is larger, and the auxiliary material ratio can be regulated between 4%～6%.
During use, at first carry out the circulating reflux processing procedure of raw material, in this process by control system control heating system and vacuum defoamation system to raw material heat, vacuum defoamation processes, when ratio regulating system 9 moves upward under the effect of hydraulic power system 2, pump body forms negative pressure, main ingredient enters major ingredient pump 3 and the first auxiliary material pump 4 or the second auxiliary material pump 5 by check valve respectively under the effect of atmospheric pressure, main ingredient will be filled respectively the main ingredient pump; When ratio regulating system 9 moved downward under the effect of hydraulic power system 2, main ingredient entered separately pipeline by check valve respectively under the effect of pressure, and by reversing globe valve and the pipeline head tank that refluxes back.
Replaced by main ingredient fully when the air in the main ingredient pump and to have finished and after the main ingredient temperature reaches requirement, can inject, be conveyed into hybrid system by the conversion reversing globe valve with main ingredient this moment, and be injected in the mould.
After injection was finished, compressed air entered purging system through pressure-regulating valve, and purging system is connected with hybrid system by pipeline, with compressed air and cleaning agent hybrid system was carried out thorough two efficiently cleanings by opening ball valve.
Embodiment recited above is described preferred embodiment of the present invention; be not that scope of the present invention is limited; design under the spiritual prerequisite not breaking away from the present invention; various distortion and improvement that the common engineers and technicians in this area make technical solution of the present invention all should fall in the definite protection domain of claims of the present invention.
