TW201615983A - Eccentric roundel structure for three-compressing-chamber diaphragm pump - Google Patents

Abstract

The present invention provides an eccentric roundel structure for three-compressing-chamber diaphragm pump. The eccentric roundel structure is a truncated-cylinder eccentric roundel in an eccentric roundel mount. The truncated-cylinder eccentric roundel characteristically comprises an annular positioning dent, a truncated cylinder peripheral and a sloped top ring created from the annular positioning dent to the truncated cylinder peripheral to replace a conventional rounded shoulder. By means of the sloped top ring, the oblique pull and squeezing phenomena of high frequency incurred by the rounded shoulder in a conventional tubular eccentric roundel are completely eliminated. Thus, not only the durability of the three-compressing-chamber diaphragm pump for sustaining the pumping action of high frequency from the truncated-cylinder eccentric roundels is mainly enhanced but also the service lifespan of the three-compressing-chamber diaphragm pump is exceedingly prolonged.

As shown in FIG. 11 and FIG. 12, it is the operation mode of the above-mentioned conventional three-pressure chamber diaphragm pump. When the output shaft 11 of the motor 10 rotates, the tilting eccentric cam 40 is rotated, and at the same time, the balance wheel housing 50 is The three cylindrical balance wheels 52 sequentially generate up and down reciprocating motions, and the three piston actuating regions 74 on the diaphragm piece 70 are also actuated by the three cylindrical balance wheels 52, which are pushed up and simultaneously in synchronization. Pulling down to produce a repeated up and down displacement, so when the cylindrical balance 52 moves down At the same time, the piston actuating region 74 of the diaphragm 70 and the piston pusher 80 are pulled downward, so that the piston piece 98 of the piston valve body 90 is pushed open, and the tap water W from the water inlet 21 of the pump head cover 20 is passed through the water inlet hole 97. And entering the plenum chamber 26 (as indicated by the arrow W in FIG. 11 and its enlarged view); when the cylindrical balance 52 is pushed up, the piston actuation zone 74 and the piston of the diaphragm 70 are simultaneously synchronized. The push block 80 is topped up, and the water in the pressurizing chamber 26 is squeezed to increase the water pressure to between 80 psi and 100 psi, so that the boosted high pressure water Wp can stop the drain seat 92. The reverse rubber pad 94 is pushed open, and continuously flows into the high pressure water chamber 27 through the drain holes 95 of the drain seat 92, and then exits the diaphragm booster pump through the water outlet 22 of the pump head cover 20 (see FIG. 12 and The arrow Wp in its enlarged view, in turn, provides the water pressure required for reverse osmosis filtration of the RO membrane tube in the reverse osmosis water filter.

As shown in FIG. 13 and FIG. 14 , when the above-mentioned conventional three-pilot diaphragm pump is actuated, the three cylindrical balance wheels 52 are pushed by the rotation of the tilting eccentric cam 40, and each of the diaphragm plates 70 is pushed upwardly. a piston actuating zone 74, which is equal to the position of the three piston actuating zones 74 on the bottom surface of the diaphragm 70, is continuously applied with an upward force F, and each time the bottom surface of the diaphragm 70 is pushed up by the force F, The downward bucking force Fs is also generated synchronously, and the magnitude distribution of the force acts on the diaphragm piece 70 on each piston actuating zone 74 (as indicated by the distribution arrow of each size rebounding force Fs in Fig. 14). The bottom surface of the diaphragm 70 at the position of the three piston actuation zones 74 is caused to be squeezed, wherein the diaphragm 70 is placed in contact with the intersection of the horizontal top surface 53 and the rounded corner 57 in the cylindrical balance 52. The bottom surface position P is subjected to the maximum degree of squeezing (as shown in FIG. 14). Therefore, at the rotational speed of the output shaft 11 of the motor 10 up to 700-1200 rpm, the bottom surface position P of each piston actuation region 74 in the diaphragm 70 is At least 4 times per second squeezed, but at such a high Under the frequency of the number of extrusions, the bottom surface position P of the diaphragm 70 is the earliest position where the crack occurs, and the main reason for the entire three-pressure diaphragm pump not being able to operate normally and reducing its service life is also caused. Therefore, how to eliminate the bottom surface of the piston actuating region 74 of the diaphragm 70, which is easily broken by the high-frequency pushing and pushing of the cylindrical balance 52, has become an urgent problem to be solved.

The main object of the present invention is to provide an "improvement of the balance structure of a three-charged diaphragm pump", which is to position a concave ring groove on a horizontal top surface of each cylindrical balance of the balance wheel to a vertical side surface. The curved surface is inclined downwardly, so that after the motor output shaft of the diaphragm booster pump rotates, the three cylindrical balance wheels are rotated by the tilting eccentric cam to push up the bottom surface of the diaphragm in the piston actuating area. The circular groove on the horizontal top surface of a cylindrical balance wheel is inclined downwardly to the vertical side surface, and the bottom surface of the diaphragm piston is not crushed by the bottom surface of the piston working area, so it can be completely eliminated. When the conventional three-pressure diaphragm pump is actuated, the rounded corners at the intersection of the horizontal top surface and the vertical side surface of each cylindrical balance wheel may cause easy cracking due to high frequency extrusion of the bottom surface of the diaphragm piston operating area. The lack of, in addition to greatly improving the tolerance of the diaphragm to withstand the high frequency push of the cylindrical balance, it is more effective to extend the service life of the entire three plenum diaphragm pump.

Another object of the present invention is to provide an "improvement of the balance structure of a three-charged diaphragm pump", which is to position a concave ring groove on a horizontal top surface of each cylindrical balance of the balance wheel to a vertical side surface. The region is provided with a downwardly inclined curved surface, so that after the motor output shaft of the diaphragm booster pump rotates, the three cylindrical balance wheels are rotated by the tilting eccentric cam to push up the bottom surface of the diaphragm in the piston actuation region. The upward force causes an upwardly inclined state of the diaphragm body between the positioning collar and the outer rib in the diaphragm, by positioning the concave ring groove on the horizontal top surface of each cylindrical balance to the vertical side The curved surface which is inclined downward can avoid the bottom surface of the diaphragm in the diagonally pulled state, and does not cause the squeezing and squeezing of the bottom surface of the diaphragm piston working area, and the diaphragm is subjected to the upward force. The rebound force generated by the synchronization is greatly reduced, so the work of the motor can be effectively reduced. The current load and working temperature, at the same time, will not cause high-temperature evaporation of the lubricating oil in the motor bearing, resulting in the lack of abnormal sound caused by poor lubrication, in addition to ensuring that all the bearings in the three-pressure diaphragm pump are running smoothly. In addition, due to the reduced operating current of the motor, the cost of electricity and electricity is reduced, and the multiple benefits of extending the service life of the entire three-bore diaphragm pump are combined.

As shown in FIG. 15 to FIG. 18, the first embodiment of the "improvement of the balance structure of the three-charged diaphragm pump" of the present invention is a horizontal top surface 53 of each cylindrical balance 52 of the balance wheel housing 50. The upper surface of the positioning concave ring groove 55 to the vertical side surface 56 is provided with a curved surface 58 which is inclined downward.

As shown in FIG. 19 to FIG. 21, when the first embodiment of the present invention "Improvement of the balance structure of the three-pilot diaphragm pump" is actuated, the three cylindrical balance wheels 52 are rotated by the tilting eccentric cam 40. After the bottom surface of the diaphragm 70 of the piston actuating region 74, the upward force F causes the diaphragm body between the positioning ring block 76 and the outer rib 71 in the diaphragm 70 to be inclined upward. By positioning the concave ring groove 55 on the horizontal top surface 53 of the cylindrical balance 52 to the downwardly inclined curved surface 58 of the vertical side surface 56, the diaphragm piece 70 contacting the obliquely pulled state can be completely avoided. The bottom surface of the region 74 does not cause a squeezing phenomenon on the bottom surface of the piston actuation region 74 of the diaphragm 70 (as shown in Figs. 19 and 20), so that the rebound force Fs generated by the diaphragm 70 is also synchronized. As a result, as shown by the arrow distribution of each size rebound force Fs in FIG. 20, it is known that the present invention can make the diaphragm sheet 70 synchronously generate a rebound by comparing it with the magnitude rebound force Fs of FIG. The force Fs is greatly reduced. Therefore, by positioning the concave ring groove 55 on the horizontal top surface 53 of the cylindrical balance 52 of the present invention to the vertical side surface 56, the downwardly inclined curved surface 58 can completely eliminate the conventional three. The rounded corner 57 of the cylindrical balance wheel 52 in the plenum diaphragm pump, which is easily broken by the high frequency 〝 〞 底面 底面 ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( And after the diaphragm 70 is subjected to the upward force F, the rebound force Fs is synchronously generated. The effect of reducing the width enables the diaphragm 70 to greatly improve the tolerance of the high-frequency pushing action of the cylindrical balance 52, and can effectively reduce the working current load and operating temperature of the motor 10, and further the lubricating oil in the bearing of the motor 10. It will not cause the lack of lubrication due to poor lubrication caused by high-temperature evaporation, in addition to ensuring that all the bearings in the three-pilot diaphragm pump are running smoothly, and the operating current of the motor 10 is reduced to reduce the cost of electricity and electricity. At the same time, the utility model has the advantages of extending the service life of the entire three-pressure diaphragm pump, and the invention is installed on the conventional three-pressure diaphragm pump and the measured result shows that the operating temperature of the motor 10 can be reduced by at least 15 ° C. The working current can be reduced by more than 1 amp, and the service life of the diaphragm 70 and the entire three plenum diaphragm pump can be increased by more than two times.

As shown in FIG. 22 to FIG. 24, in the second embodiment of the present invention, "the improvement of the balance structure of the three-charged diaphragm pump" is to increase the diameter of each of the cylindrical balances 502 in the balance wheel holder 500. However, it is still smaller than the inner diameter of the actuating perforation 61 in the pump head housing 60, and the side surface thereof is provided with an inwardly concave arc. The side surface 506 is shaped, and the area of the horizontal top surface 503 of each cylindrical balance 502 that is positioned with the concave ring groove 505 to the curved side surface 506 is further provided with a downward slope 508.

As shown in FIG. 25 to FIG. 27, when the second embodiment of the present invention "improvement of the balance structure of the three-pilot diaphragm pump" is actuated, the three cylindrical balance wheels 502 are rotated by the tilting eccentric cam 40 to push up the piston. When the bottom surface of the diaphragm 70 of the actuating portion 74 is actuated, the upward force F causes the diaphragm body between the positioning ring block 76 and the outer rib 71 in the diaphragm 70 to be inclined upwardly by the cylinder. The downward inclined surface 508 of the horizontal top surface 503 of the balance wheel 502 is positioned to the downward inclined surface 508 of the curved side surface 506, and can be completely flush contact and supported on the bottom surface of the diaphragm sheet 70 in the diagonally pulled state without The phenomenon that the bottom surface of the diaphragm actuation region 74 of the diaphragm 70 is compressed by the crucible (as shown in FIGS. 25 and 26), and the rebound force Fs generated by the diaphragm 70 is also greatly reduced (as shown in FIG. 26). The design of the inwardly concave curved side surface 506 is designed according to the arrow shape distribution of the concave rebound force Fs of each size, and the cylindrical balance wheel 502 can be prevented from colliding when it is pushed up by the upward movement. Connected to the wall surface of the pump head 60 to actuate the perforation 61, and thus, by the cylindrical balance 502 of the present invention Positioning the concave ring groove 505 on the horizontal top surface 503 to the downward slope 508 of the curved side surface 506, except that the bottom 57 of the cylindrical balance 502 in the conventional three-pressure diaphragm pump can be completely eliminated to the bottom surface of the diaphragm 70 The piston actuating region 74 generates a defect of the squeezing squeezing (as shown by the imaginary line portion in Fig. 27), and has the effect of substantially reducing the rebounding force Fs when the diaphragm 70 is subjected to the upward force F. The diaphragm 70 can greatly improve the tolerance of the high-frequency thrust of the cylindrical balance 502, thereby effectively extending the service life of the entire three-pressure diaphragm pump. In addition, since the diameter of the cylindrical balance 502 is increased, the area of the downward inclined surface 508 is also increased, so that the area of the bottom surface of the diaphragm sheet 70 which is in contact with the obliquely pulled state can be increased during the operation (as shown in FIG. 27). A shows), and increases the support for the rebound force Fs, thereby reducing the degree of influence of the diaphragm 70 on the rebound force Fs, and also the use of the diaphragm 70 Life expectancy is extended.

As shown in FIG. 28 to FIG. 30, in the second embodiment of the present invention, "the structure of the balance of the three-pilot diaphragm pump is improved", the curved side of each of the cylindrical balances 502 of the balance wheel holder 500 is concave. On the side surface, the upright section 509 (shown in FIG. 29) which is set to be inwardly reduced and bent can be changed, and it can still be avoided when the diameter of the cylindrical balance 502 is increased and the displacement is pushed upward. The effect of actuating the wall surface of the hole of the perforation 61 in the pump head holder 60 is as shown in Fig. 30.

As shown in FIG. 31 to FIG. 34, it is a third embodiment of the "improvement of the balance structure of the three-pilotted diaphragm pump" of the present invention, wherein each of the cylindrical balances 502a of the balance wheel holder 500a can be modified. It is composed of a cylindrical seat 511 and a balance ring 521; a circumferential plane 512 is disposed on the circumferential outer edge surface of the cylindrical seat 511, and a convex cylinder 513 is protruded from the top surface, and the top of the convex cylinder 513 A concave hole 514 is defined in the concave portion of the surface; the balance ring 521 is sleeved on the cylindrical seat 511, and the outer peripheral surface thereof is provided with an inwardly concave curved side surface 522, and is disposed at the center of the top surface toward the bottom surface. The upper hole 523, the middle hole 524 and the lower hole 525 intersect with each other, wherein the diameter of the upper hole 523 is larger than the outer diameter of the convex cylinder 513 of the cylindrical seat 511, and the inner diameter of the intermediate hole 524 and the cylindrical seat 511 The outer diameter of the convex cylinder 513 is the same, the inner diameter of the lower hole 525 is the same as the outer diameter of the cylindrical seat 511, and the area from the upper hole 523 to the curved side surface 522 is set to the downward slope 526, and the balance is rounded. After the ring 521 is sleeved on the cylindrical seat 511, a positioning concave ring groove 515 can be formed between the convex cylinder 513 and the upper step hole 523 of the balance ring 521 (as shown in the figure). 33 and Figure 34).

As shown in FIG. 35 to FIG. 38, after each balance ring 521 of the balance wheel holder 500a is engaged with the cylindrical seat 511, the three positioning convex ring blocks 76 on the bottom surface of the diaphragm piece 70 are respectively inserted. In the three cylindrical seats 511 of the balance wheel base 511, the convex cylindrical 513 and the upper end hole 523 of the balance ring 521 are positioned in the concave groove 515, and then the step of inserting the piston push block 80 by the fixing screw 1 Hole 81, and After passing through the central perforation 75 of the three piston actuating regions 74 of the diaphragm 70, the diaphragm piece 70 and the three-piston push block 80 can be simultaneously screwed into the threaded holes 514 of the three cylindrical seats 511 of the balance wheel seat 500a (as shown in the figure). When the output shaft 11 of the motor 10 is rotated, the balance ring 521 of the three cylindrical balance wheels 502a is rotated by the inclined eccentric cam 40 to push up the bottom surface of the diaphragm 70 of the piston actuation region 74. When the upward force F is applied, the diaphragm body between the positioning convex ring block 76 and the outer convex strip 71 in the diaphragm 70 is in an upwardly inclined state, and the balance ring of the cylindrical balance 502a The downward inclined surface 526 between the positioning concave ring groove 515 and the curved side surface 522 of the 521 can be completely flush contact and supported on the bottom surface of the diaphragm sheet 70 in the diagonally pulled state without the bottom surface of the diaphragm piece 70. The phenomenon of squeezing squeezing is generated (as shown in FIG. 36 and FIG. 37), and the rebound force Fs generated by the diaphragm 70 is also greatly reduced (as shown in FIG. 37, the arrow distribution of the rebound force Fs of each size) Shown), while the concave curved side surface 522 is designed, still due to the diameter of the cylindrical balance 502a, When the upward thrust displacement is actuated, it can avoid hitting the wall surface of the hole in the pump head seat 60 for actuating the perforation 61 (as shown in FIG. 36), so that it can completely eliminate the cylindrical pendulum in the conventional three-pressure diaphragm pump. The rounded corner 57 of the wheel 502 produces a squeezing flaw on the bottom surface of the diaphragm 70 (as indicated by the imaginary line portion in Fig. 38), and still has a rebound force when the diaphragm 70 is subjected to the upward force F. The effect of the large reduction of the force Fs enables the diaphragm 70 to greatly increase the tolerance of the high-frequency thrust of the cylindrical balance 502, thereby effectively extending the service life of the entire three-pressure diaphragm pump, and in addition to the second implementation described above. In the case of the same effect, the balance ring 521 having the inwardly concave curved side surface 522 and the downward inclined surface 526 must be considered in the production process, so that it must be considered with the balance wheel. The seat 500a is separately manufactured to save the manufacturing cost, and the cylindrical seat 511 can be integrally formed with the balance seat 500a, and then the two are combined into a cylindrical balance 502a. Therefore, the structural design has completely Comply with industrial mass production and save overall Manufacturing dual benefit costs.

Another embodiment of the conventional three-pilot diaphragm pump balance wheel 50a and diaphragm 70a is shown in Figs. 44 to 49, wherein the level of each cylindrical balance 52a in the balance seat 50a is shown. The top surface 53 is recessed downwardly into a positioning groove 551, and a threaded hole 541 (shown in FIGS. 44 and 45) is disposed downward in the center of the bottom surface of the groove, and each piston in the diaphragm 70a is actuated. The bottom surface of the central perforation 75a of the region 74a is convexly disposed to form a positioning projection 77 (as shown in FIGS. 47 and 48), and the positioning recess is recessed downward by the horizontal top surface 53 of the cylindrical balance 52a. The groove 551 can still achieve the function of fitting and fixing with the positioning protrusion 77 on the bottom surface of the diaphragm piece 70a (as shown in FIG. 49).

As shown in FIG. 50 to FIG. 53, a fourth embodiment of the present invention is a modification of the balance structure of a three-charged diaphragm pump, which is a pendulum according to another embodiment of the conventional three-pressure diaphragm pump. The wheel base 50a and the diaphragm piece 70a are designed to provide a downwardly inclined curved surface 59 in a region in which the positioning groove 551 to the vertical side surface 56 of each cylindrical balance 52a of the balance wheel seat 50a is provided (for example).
