As shown in Figures 10 and 11, it is the flowing mode of doing of above-mentioned known five booster cavity diaphragm pumps, after the force-output shaft 11 of motor 10 rotates, can drive inclination eccentric cam 40 to rotate, and make five escapements 52 on escapement seat 50 sequentially produce the reciprocal start that is upper and lower simultaneously, and five piston start districts 74 on diaphragm 70, also can be subject to the start up and down of five escapements 52, synchronously by pushing tow up and toward drop-down and produce upper and lower displacement repeatedly, therefore, when escapement 52 is down when start, synchronously by the piston start district 74 of diaphragm 70 and piston thrust block 80 toward drop-down, the piston sheet 98 of piston valve body 90 is pushed open, and in the future the tap water W of self-pumping skull 20 water intakes 21 via water inlet 97, and enter in pressurized chamber 26 (as shown in the arrow W in Figure 10 and zoomed-in view thereof), when escapement 52 is up when pushing tow start, also synchronously each piston start district 74 of diaphragm 70 and piston thrust block 80 are up pushed up, and the water in pressurized chamber 26 is pushed, its hydraulic pressure is increased between 100psi ~ 150psi, therefore the high pressure water Wp after boosting can push the non-return rubber cushion 94 on drainage seat 92 open, and via each weep hole 95 of drainage seat 92, sequentially constantly flow in high pressure hydroecium 27, and then discharge five booster cavity diaphragm pumps outer (as shown in the arrow Wp in Figure 11 and zoomed-in view thereof) via the water outlet 22 of pump head lid 20, and then provide RO film pipe in large scale business reverse osmosis water filter to carry out the required water pressure of osmosis filtration, or in touring car, bathe kitchen water supply equipment and export required water pressure.

As shown in Figure 12 to Figure 14, there is for a long time a serious disappearance in above-mentioned known five booster cavity diaphragm pumps, in the time of its start, five escapements 52 are understood in turn the up piston start district 74 of pushing tow diaphragm 70, it equals on 74 positions, five piston start districts of diaphragm 70 bottom surfaces, constantly impose a directed force F (as shown in figure 13) upwards, be multiplied by by this directed force F the moment (being moment=F × L1) that the arm of force length L 1 between outer raised line 71 and positioning convex ring piece 76 produces, just can make the whole pump housing produce vibrations, because the rotating speed of motor 10 force-output shafts 11 is up to 800-1200 rpm, therefore it drives five escapement 52 〝 that start produces in turn vibrations 〞 intensity is to remain high always.

Therefore, as shown in figure 14, known five booster cavity diaphragm pumps all can be installed a base 100 in pump housing outer rim, in the wing plates on two sides 101 of this base 100, be respectively equipped with a pair of Rubber shock-absorbing pad 102, with retaining screw 103 and nut 104, base 100 is fixed on to reverse osmosis water filter again, or in touring car, bathes on the shell C of kitchen water supply equipment, but, in fact utilize two pairs of Rubber shock-absorbing pads 102 in these base 100 wing plates on two sides 101 to reach the effect of damping quite limited, because of the 〝 vibrations 〞 intensity that pump housing start produces very big, still can cause the sympathetic response of shell C and send the irritating sound, in addition, be arranged in the frequency that water pipe P on pump head lid 20 water outlets 22 also can shake along with 〝〞, synchronous generation is rocked (as shown in the imaginary line P in Figure 14 and a view thereof) and is slapped against other elements in contiguous reverse osmose pure-water device, if use after a period of time, also can make gradually to cause because rocking the phenomenon mutually getting loose between water pipe P and its pipe joint, finally by the result that causes leaking, many disappearances are all because the 〝 vibrations 〞 that five booster cavity diaphragm pump starts produce causes above, therefore how can significantly reduce the 〝 vibrations 〞 disappearance that this five booster cavities diaphragm pump start produces, become quite urgent problem anxious to be resolved.

Continuous as shown in Figure 15 to Figure 17, another embodiment of piston valve body 900 in known five booster cavity diaphragm pumps, its outer periphery side, bottom convexes with a ring raised line 901 downwards, can plug the space between diaphragm 70 China and foreign countries' raised lines 71 and interior raised line 72, be concaved with a circular drainage seat 902 towards the middle position of pump head lid 20 directions, on this drainage seat 902, interval 72 is spent five regional location central authorities that angle forms and is respectively equipped with a positioning hole 903, can penetrate fixing for a T-shaped piston sheet 904, another on the regional location between each positioning hole 903 and drainage seat 902, be equipped with again several weep hole 905(as shown in figure 15), and on should drainage seat 902 peripheral surface in each region, be equipped with respectively again space 72 and spend that angle is arranged and all five influent bases 906 down of opening, on each influent base 906, be equipped with again several water inlets 907, and place the T-shaped piston sheet of a handstand 904 in the central authorities of each influent base 906, wherein, weep hole 905 on drainage seat 902 each region, each influent base 906 is corresponding thereto connected respectively, the ring raised line 901 of piston valve body 900 bottoms is plugged behind the space between outer raised line 71 and the interior raised line 72 of diaphragm 70, can be between each influent base 906 and the end face of diaphragm 70, respectively be formed with the 26(of pressurized chamber of a sealing as shown in figure 17), and be covered at pump head lid 20 after the end face of piston valve body 900, the bottom of its dome ring 25 can press on the outer edge surface of drainage seat 902 in piston valve body 900, make between the internal face of this dome ring 25 and the drainage seat 902 of piston valve body 900, can around form a high pressure hydroecium 27(as shown in figure 17), pass respectively the each fixing perforation 23 of pump head lid 20 by fixing bolt 2, and by after the each fixing perforation 63 of pump head seat 60, again respectively with insert the nut 3 in each fixing perforation 63 in pump head seat 60 and be screwed, and be directly screwed in motor protecgulum 30 in each fixing perforation 33, can complete the combination (as shown in Fig. 1 and Figure 19) of whole five booster cavity diaphragm booster pumps.

As shown in figure 17, after the force-output shaft 11 of motor 10 rotates, can drive inclination eccentric cam 40 to rotate, and make five escapements 52 on escapement seat 50 sequentially produce the reciprocal start that is upper and lower simultaneously, and five piston start districts 74 on diaphragm 70, also can be subject to the start up and down of five escapements 52, synchronously by pushing tow up and toward drop-down and produce upper and lower displacement repeatedly, therefore, when escapement 52 is down when start, synchronously by the piston start district 74 of diaphragm 70 and piston thrust block 80 toward drop-down, the piston sheet 904 of influent base 906 in piston valve body 900 is pushed open, and in the future the tap water W of self-pumping skull 20 water intakes 21 via water inlet 907, and enter in pressurized chamber 26 (as shown in arrow W in Figure 17), when escapement 52 is up when pushing tow start, also synchronously each piston start district 74 of diaphragm 70 and piston thrust block 80 are up pushed up, and the water in pressurized chamber 26 is pushed, its hydraulic pressure is increased between 100psi ~ 150psi, therefore the high pressure water Wp after boosting can push the piston sheet on drainage seat 902 904 open, and via each weep hole 905 of drainage seat 902, sequentially constantly flow in high pressure hydroecium 27, and then discharge five booster cavity diaphragm pumps outer (as shown in arrow Wp in Figure 17) via the water outlet 22 of pump head lid 20, and then provide RO film pipe in reverse osmosis water filter to carry out the required water pressure of osmosis filtration, or in touring car, bathe kitchen water supply equipment and export required water pressure.

Five booster cavity diaphragm pumps of aforementioned known another embodiment's piston valve body 900 can produce equally the disappearance of very big 〝 vibrations 〞 in the time of start, therefore how can significantly reduce the disappearance of these 〝 vibrations 〞, are also quite urgent problems anxious to be resolved.
