Abstract
The utility model relates to a compound multilevel diaphragm pump, which comprises a pump body, a reducer, a crank-slider mechanism, a thrust bar and a plurality of serial disc-type diaphragm positioned on the thrust bar, wherein a left and a right driving cavity formed by a baffle are positioned between the neighboring diaphragms; a left and a right working cavity are positioned in the pump body; the two working cavities are communicated with the left and the right driving cavities respectively by two pipes; the two working cavities and the two driving cavities are filled with hydraulic medium; hose diaphragms for transporting materials are positioned in the two working cavities respectively; the upper and lower ends of the two hose diaphragms are connected to the feeding opening and discharging opening of the pump body; a discharging one-way valve and a sucking one-way valve are positioned on the upper and lower end of each hose diaphragm. The volume of the two hose diaphragms for transporting materials driven by the hydraulic medium alternately in the pump body through the reciprocating motion of the plurality of disc-type diaphragms positioned on the thrust bar is reduced or increased for transporting the materials successively. The diaphragm pump has the advantages of resisting abrasion, no leakage, lower cost, long service life and high efficiency.
Description
Technical field:
The utility model relates to the pump class, specifically a kind of compound multi-stage diaphragm pump of conveying material.
Background technique:
Common pump structure is made up of rotor, blade, impeller, pump case etc. substantially.When conveying material, material and above-mentioned parts always directly contact, and cause the leakage of wearing and tearing, erosion and even the pump of parts, not only need the expensive structural material that can resist institute's conveying material erosion, and the increase maintenance frequency, shorten dramatically the working life that makes it cost increase, pump.
Summary of the invention:
In view of the deficiency that above-mentioned prior art exists, the purpose of this utility model provides that a kind of cost is low, long service life, compound multi-stage diaphragm pump that efficient is high.
The purpose of this utility model is to realize like this, it comprises the pump housing, speed reducer and the slidercrank mechanism that links to each other with this speed reducer output shaft and the track bar that links to each other with this mechanism, it is characterized in that: the track bar of inserting in the pump housing is provided with a plurality of disc type diaphragms that are in series, between adjacent two barrier films, be provided with the left and right driving chamber that forms by dividing plate, be provided with left and right two active chambers in the pump housing, these two active chambers are connected with the left and right driving chamber by two connecting tubes respectively, are filled with hydraulic medium in two active chambers and the left and right driving chamber; Be arranged with conveying material flexible pipe barrier film in two active chambers, the upper/lower terminal of two flexible pipe barrier films links to each other with the charging and discharging mouth of the pump housing respectively, is arranged with at the upper and lower end of each flexible pipe barrier film and discharges one-way valve and suck one-way valve.Do straight reciprocating motion by speed reducer drive slidercrank mechanism and track bar, by being located at the to-and-fro motion of a plurality of disc type diaphragms on the track bar, make the hydraulic medium driven two conveying material flexible pipe barrier film work in pump housing left and right driving chamber and the left and right active chamber, its volume is dwindled or increase, thereby finish the conveying of material.
The utility model has the advantages that conveying material does not directly contact with the workpiece of pump, thereby it is corrosion-resistant, wear-resistant, adopt a plurality of disc type diaphragms that are in series to form multistage barrier film, gain in strength greatly, not fragile, leakage, cause user cost greatly to reduce, increase the service life, two conveying material flexible pipe barrier film alternations can be increased work efficiency greatly.
Below in conjunction with accompanying drawing the utility model is explained.
Description of drawings:
Accompanying drawing is the utility model structural representation.
Embodiment:
By accompanying drawing as can be known, this compound multi-stage diaphragm pump comprises speed reducer 1, slidercrank mechanism 2 (identical with the existing slidercrank mechanism of doing straight reciprocating motion, Gu Tuzhong does not provide in detail), track bar 3 and by the pump housing 16, four disc type diaphragms that are in series 7, dividing plate 6, hydraulic medium 21, flexible pipe barrier film 8,12, charging and discharging mouths 14,10 and suck one- way valve 15,13 and discharge the material-handling pump that one-way valve 9,11 constitutes.Slidercrank mechanism 2 links to each other with speed reducer 1 output shaft, slide block links to each other with track bar 3, four disc type diaphragms that are in series 7 are connected with track bar 3 in inserting the pump housing 16, the periphery of four disc type diaphragms 7 and the pump housing 16 inwalls are connected, between adjacent two disc type diaphragms 7, be provided with dividing plate 6, these dividing plate 6 both sides are divided into a left side, right actuator chamber 5,4, be provided with a left side in the pump housing 16, right two active chambers 19,20, these two active chambers are respectively by two connecting tubes 17,18 with left, right actuator chamber 5,4 are connected, two active chambers 19,20 and left, right actuator chamber 5, be filled with hydraulic medium 21 in 4; Two conveying material flexible pipe barrier films were located in left and right two active chambers 19,20 in 8,12 minutes, the upper/lower terminal of two flexible pipe barrier films 8,12 links to each other with the charging and discharging mouth 14,10 of the pump housing respectively, is arranged with at the upper and lower end of two flexible pipe barrier films 8,12 and discharges one-way valve 9,11 and suck one-way valve 15,13.Disc type diaphragm 7 and flexible pipe barrier film 8,12 adopt soft elastic material to make, as nitrile butadiene rubber, neoprene, fluorine rubber etc.Hydraulic medium 21 adopts hydraulic oil, adds antiwear additive, antioxidant, anti-vulcanzing agent etc. in this hydraulic oil, makes it disc type diaphragm, the flexible pipe barrier film is anti-aging, increases the service life.When track bar 3 drives four disc type diaphragms 7 when reciprocating, dwindle or increase by hydraulic medium 21 driven flexible pipe barrier films 8 or 12 internal volumes.When flexible pipe barrier film 8 internal volumes increase, discharge one-way valve 9 and close, suck one-way valve 15 and open, flexible pipe barrier film 8 sucks material, and this moment, flexible pipe barrier film 12 internal volumes dwindled, and discharged one-way valve 11 and opened, and sucked one-way valve 13 and closed, and flexible pipe barrier film 12 is discharged material; When flexible pipe barrier film 8 internal volumes dwindle, discharge one-way valve 9 and open, suck one-way valve 15 and close, flexible pipe barrier film 8 is discharged material, and this moment, flexible pipe barrier film 12 internal volumes increased, and discharged one-way valve 11 and closed, and sucked one-way valve 13 and opened, and flexible pipe barrier film 12 sucks material.This process is gone round and begun again, and material is transferred out continuously.Adopt a plurality of slidercrank mechanisms to form corresponding angle (do not omit among the figure and change), make not backlash of drive part, realize high efficiency.
