Description of drawings
Fig. 1 is a structure diagram of the present invention.
Specific implementation
As shown in Figure 1, superposed two material acting chambers 9 of isolating mutually communicate with the oil plant acting chamber 12 that is positioned at its below by two barrier film mechanisms 8 respectively, and being positioned at material acting chamber 9 tops has a material feeding mouth valve 10 and discharge port valve 11.Epicyclic train drives plunger push rod 16 promotion plungers 1 and do straight reciprocating motion in oil plant acting chamber 12, and oil-supplementing system comprises a disk spring type barrier film mechanism 8 that is vertically superposeed and formed by the bellow type structural member.In the both sides of material acting chamber 9 a barrier film mechanism 8 is arranged respectively, the guide and limit bar 7 that is installed in the barrier film mechanism 8 can slide in guide pipe 6, and guide pipe 6 communicates with repairing pipe 5, and the end of guide and limit bar 7 is over against the top of Fill valve 3.Bellow type structural member in the butterfly-valve barrier film mechanism adopts metallic material to make, and when plunger 1 was inhaled pressure oil, barrier film mechanism 8 elongated or shortened, and makes the material in the material acting chamber 12 suck or extrude.
Epicyclic train is formed by internal gear 13, with internal gear 13 planet gear meshed 15, and the gear ratio of planetary pinion 15 and internal gear 13 is 1: 2, and planetary pinion 15 is installed in the rotating shaft O of tie-rod 14
2On, rotating shaft O
3Fixedly connected with planetary pinion 15.Planetary pinion 15 drives rotating shaft O
3, plunger push rod 16, drive plunger 1 is done straight reciprocating motion in oil plant acting chamber 12.As shown in Figure 2, when planetary pinion 15 revolves round the sun, a bit all did the straight reciprocating motion at internal gear 13 centers arbitrarily on planetary pinion 15 pitch circles, in internal gear 13 by the bearing pin O of planetary pinion 15 pitch circles
3Drive 16 to-and-fro motion of plunger push rod.When power is imported by tie-rod 14, when driving planetary pinion 15 revolution, plunger 1 to-and-fro motion about plunger push rod 16 is driven in two oil plant acting chambers 12, pass motion to butterfly-valve barrier film mechanism 8 by fluid, barrier film mechanism 8 elongates or shortens, in material acting chamber 9, carry out the action of suction or binder, finish feeding work by material feeding mouth valve 10 and discharge port valve 11.
As shown in Figure 1, the top of guide and limit bar 7 links to each other with uppermost video disc in the barrier film mechanism 8, can slide in guide pipe 6 in its lower end.Be installed in the opposite Fill valve of both direction (one-way valve) 2 is arranged in the repairing pipe 5,3 and oil feeding reservoir 4, when the oil mass in the oil plant acting chamber 12 is sufficient, barrier film mechanism 8 is in the telescopic process, oil-supplementing system is failure to actuate, along with the generation of leaking, plunger 1 oil suction, moving to Fill valve 3 along guide pipe 6 of guide and limit bar 7 is along with plunger 1 continues motion, when the contour projector of barrier film mechanism 8 reaches the permission minimum value, guide and limit bar 7 backs down Fill valve 3 downwards, begin from oil feeding reservoir 4 oil suctions, Fill valve 3 restriction barrier film mechanisms 8 continue to shrink simultaneously, when plunger 1 is pressed oil, one-way valve 2 cuts off oil circuit, and system carries out the normal circulation process.The span of the angle α of guide and limit bar 7 is in the axis of plunger 1 and the barrier film mechanism 8: 180 °＞α＞0 °.
Butterfly-valve barrier film mechanism among the present invention is an a kind of spring mechanism, and adopts metallic material to make, long service life, and can the higher material of delivery temperature.The epicyclic train that the present invention adopts will rotatablely move and change the straight reciprocating motion that does not have the inclination angle of plunger push rod into, and the plunger non-lateral pressure is produced, and reduce frictional force.No plane general motion parts in the mechanical transmission mechanism make system running steadily, vibrate for a short time, and noise is low.Compare with above-mentioned existing patented technology, long service life, under same cylinder diameter, same rotating speed, tie-rod and the situation of crank with length, discharge capacity is four times of curved shaft type diaphragm pump.
