Abstract
A hydraulic diaphragm pump comprises a hydraulic motor, a transmission seat body, a pump body, a feed tube, a discharge tube, one-way ball valves and an eccentric device and is characterized in that a cycloidal pinwheel type reducer is arranged between the hydraulic motor and the transmission seat body; the pump body is separated into a left pump body and a right pump body of two cavities by a diaphragm; a cam type eccentric device is arranged between the two pump bodies; the one-way ball valve is arranged respectively between the two inlet ends of the feed tube and the outlet end of the left pump body and between the two inlet ends of the feed tube and the outlet end of the right pump body; and a ring-shaped structure is formed by the left pump body, the right pump body, the feed tube, the discharge tube and four one-way ball valves. The hydraulic diaphragm pump has simple structure, low manufacture cost, small volume, convenient operation and use, simple maintenance and long service life, and can be widely used in the media transportation in petrochemical, ceramic, construction and food industries and the like.
Description
Technical field
The utility model relates to a kind of diaphragm pump that surges.
Background technique
Diaphragm pump structure of the prior art is by barrier film the inner space of pump to be divided into two-part operative section and action part, its action part is the to-and-fro motion of adopting piston, propelling fluid moves back and forth barrier film, to reach the reciprocal operating type that operative section is drawn and discharged, its complex structure, assembly are many, volume is big, and working life is short, the manufacture cost height.
Summary of the invention
The purpose of this utility model is to be to overcome above-mentioned deficiency, provides a kind of simple in structure, a kind of diaphragm pump that surges that volume is little, cost is low, long service life, transmission device and medium separate.
The technical solution of the utility model: a kind of diaphragm pump that surges, comprise oil hydraulic motor, transmission pedestal, the pump housing, supply pipe, discharge nozzle, non-return valve and eccentric, it is characterized in that being provided with retarder between oil hydraulic motor in the described diaphragm pump that surges and the transmission pedestal, its retarder one end links to each other with oil hydraulic motor, the other end links to each other with the transmission pedestal, and the other end of transmission pedestal connects the pump housing; The described pump housing separates the left pump housing and the right pump housing that becomes two chambeies by barrier film, between two pump housings eccentric is set, and promptly the eccentric left end is connected with barrier film on the left pump housing, and right-hand member is connected with barrier film on the right pump housing;
Described supply pipe and discharge nozzle are crotch formula structure, between two outlet end of its supply pipe and left pump housing entrance point and the right pump housing entrance point non-return valve is set respectively, go out respectively to be provided with a non-return valve between two entrance points of discharge nozzle and left pump housing outlet end and the right pump housing outlet end, its left pump housing, the right pump housing, supply pipe, discharge nozzle and four non-return valves are formed loop configuration.Retarder is a cycloidal-pin wheel formula retarder.Eccentric is the cammingly eccentric.Originally the diaphragm material that surges in the diaphragm pump can adopt butadiene acrylonitrile rubber, food rubber, materials such as fluorine rubber and teflon.
Originally the surge working principle of diaphragm pump: during work, after oil hydraulic motor reaches the required rotating speed of diaphragm pump through cycloidal-pin wheel formula retarder, driving the cammingly eccentric makes the left pump housing and the right pump housing that barrier film is housed reciprocating, motion by the pump inner septum changes a left side, the volume of right pump housing active chamber produces certain pressure, make four non-return valve opening and closing regularly in the diaphragm pump that surges, as: two non-return valves of left end are opened, two non-return valves of right-hand member this moment cut out, its medium flows out from left end, close as two non-return valves of left end, two non-return valves of right-hand member this moment are opened, and its medium flows out from right-hand member; Thereby medium is constantly sucked and export, finish whole transportation process.
In sum, originally the diaphragm pump structure that surges is simple, fabricating cost is low, and volume is little, and is easy for operation, gearing separates with fed sheet of a media, its medium can not leak and damage mechanical parts, and this pump need not the leakproof oil sealing, safeguards simple, long service life can be widely used in petrochemical industry, pottery, building, the lower (outlet pressure≤3Kg/cm of food equal pressure
2) little (flow≤8m of flow
3/ h) inhale that journey is short (inhales the industry medium transport of journey≤6m).
