Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is side view embodiment illustrated in fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
As depicted in figs. 1 and 2: a kind of gas boosting pump, air input joint 1, the air inlet seat 2 connected successively from top to bottom, take a breath seat 6, cylinder barrel 9, guide holder 13, supporting base 15 and support 20 is comprised; Air inlet seat 2, ventilation seat 6, guide holder 13, run through connection by jointed connecting rod 19 between supporting base 15 and support 20, jointed connecting rod 19 has three, lay respectively at centre and the two ends of the pump housing, for the stable pump housing, the top and bottom of jointed connecting rod 19 are fixed by bolt 21.
The side of air input joint 1 is provided with low-pressure admission mouth 24, and be pressurized medium for input, being pressurized medium is air or high-purity gas, as hydrogen, nitrogen, helium, oxygen etc.; Closed air-inlet cavity 25 is formed between air inlet seat 2 and ventilation seat 6, can for needing the gas boosting of supercharging; Air-inlet cavity 25 is by the inner chamber break-make of air-intake valve plate 7 with cylinder barrel 9; The inner chamber of cylinder barrel 9 is provided with reciprocating piston assembly 10, and the both sides of piston assembly 10 are provided with piston ring; Piston assembly 10 coaxially connects one end of pull bar 11; The other end of pull bar 11 stretches out from the inner chamber of guide holder 13, is connected one end of connecting rod 18 by bearing pin 17, and bearing pin 17 and connecting rod 18 are arranged in sliding sleeve 16, and sliding sleeve 16 is arranged in the inner chamber of supporting base 15; The inner chamber of the guide holder 13 be connected with pull bar 11 is provided with seal ring 12 and guide sleeve 14; The other end of connecting rod 18 connects motor 23 by crank 22; Crank 22 is installed on the inside of support 20, and the outside of support 20 is provided with motor 23.
Wherein, the swing of connecting rod 18 can be transferred to the straight line motion of pull bar 11 by guide holder 13 and guide sleeve 14, and straight line motion significantly can improve the life-span of piston ring.In addition, because existing pressurizing air press (pump) is only by piston ring packing, reliability is lower, must some be spilt by piston ring by the gas compressed, after the present embodiment adds seal ring 12, make gas boosting pump have the double seal of piston ring and seal ring 12, greatly improve and be pressurized the externally airtight reliability of gas.
The inner chamber of cylinder barrel 9 is by high pressure outlet air mouth 26 break-make of nonreturn valve core 5 with ventilation seat 6; Nonreturn valve core 5 is located in the pressure cap 3 of air inlet seat 2 inner chamber, and the upside of nonreturn valve core 5 is provided with spring 4, plays buffer function; Pressure cap 3, spring 4 and nonreturn valve core 5 entirety closely cooperate and are assembled in ventilation seat 6, and pressure cap 3 is pressed between ventilation seat 6 and the end face of air-inlet cavity 25.The top and bottom of cylinder barrel 9 all in be provided with seal ring 8, prevent Leakage Gas.
Working principle of the present utility model is:
(1) low-pressure admission process: gas will be pressurized and input from low-pressure admission mouth 24, air-inlet cavity 25 is entered through air inlet seat 2, gas is inputted from low-pressure admission mouth 24 due to slowly continuous, gas is compressed in the air-inlet cavity 25 of sealing, the pressure increase of intracavity gas, when this pressure increase is to when being enough to the spring compression force overcoming air-intake valve plate 7, air-intake valve plate 7 is opened, and gas enters the inner chamber of cylinder barrel 9 by air-intake valve plate 7; After stopping feeding gas to air-inlet cavity 25, the pressure of intracavity gas reduces gradually, and when this pressure is decreased to the spring compression force being less than air-intake valve plate 7, air-intake valve plate 7 is closed, and completes low-pressure admission process.
(2) high pressure outlet air process: motor 23 is swung by crank 22 drivening rod 18, connecting rod 18 drives pull bar 11 to move again, due to the effect of guide holder 13 and guide sleeve 14, the swing of connecting rod 18 transfers the straight line motion of pull bar 11 to, and pull bar 11 promotes piston assembly 10 to-and-fro motion; When piston assembly 10 moves downward, the gas storage cavity of cylinder barrel 9 increases, and intracavity gas pressure reduces, and is less than the spring compression force of nonreturn valve core 5, makes nonreturn valve core 5 still be in closed condition; When piston assembly 10 moves upward, the gas storage cavity of cylinder barrel 9 reduces, intracavity gas pressure increase, when this pressure increase is to when being enough to the spring compression force overcoming nonreturn valve core 5, nonreturn valve core 5 is opened, and pressurized gas export from high pressure outlet air mouth 26 through nonreturn valve core 5, now piston assembly 10 continues to move downward, after nonreturn valve core 5 is closed, motor 23 quits work, and completes high pressure outlet air process.
