Abstract
A pneumatic-hydraulic membrane pump for pharmacy, mainly applied to process units for Freon-free pharmaceutical aerosol (HFA), comprises an upper pump body (2), a lower pump body (5), a membrane sheet(1) and the like. The upper pump body (2) is connected with the lower pump body (5), and is provided with the membrane sheet (1), an oil chamber (3) of the upper pump body (2) is filled with hydraulic oil, the other end of the upper pump body (2) is connected with a cylinder of a production line, and a piston rod (4) of the cylinder passes through the oil chamber (3) of the upper pump body (2), and is provided with a seal ring (10). The piston rod (4) uses the hydraulic oil to drive the membrane sheet (1) to implement reciprocative motion, thus liquid medicine can be pumped to supply. The pneumatic-hydraulic membrane pump for pharmacy is capable of stabilizing and precisely controlling pressure of delivered liquid medicine. The employment of hydraulic oil plays a role in cushioning, wellprotects the membrane sheet, and extends service life of the membrane sheet.
Description
Technical field
The utility model is the pharmaceutical purpose pneumatic hydraulic diaphragm pump that uses in a kind of drugs manufacture equipment, and specifically a kind of pharmaceutical purpose pneumatic hydraulic diaphragm pump that is mainly used in no freon medicinal aerosol (HFA) process units also can be used for other drugs manufacture equipment.
Technical background:
Medicinal aerosol has been a common formulations abroad, is characterized in rapid-action, side effect is little, does not need through GI absorption the utilization ratio of drug height.Medicinal aerosol can be divided into two kinds of three-phase suspension type (gas phase, liquid phase, solid phase) and two-phase solution-types (gas phase, liquid phase), and wherein three-phase suspension type technical specifications require high.China's two-phase solution-type medicinal aerosol that begins one's study from the sixties, but make slow progress, it is also very slow to produce the corresponding Equipment Development of medicinal aerosol.The country that can produce the medicinal aerosol equipment of three-phase supensoid agent at present in the world also has only a few company of a few countries such as Switzerland, Italy.
According to " GMP " requirement to the drugs manufacture equipment parts, the part of contact material must not pollute material, and parts do not have the corner or spot as yet untouched by a clean-up campaign.And be used at present not having freon medicinal aerosol (HFA) process units use be membrane pump with pneumatic drive, adopt the direct driven diaphragm of pressurized air, because pressurized air has compressibility, be difficult to realize the pressure control of the precision of institute's fed sheet of a media, and can cause shorten the working life of diaphragm.
Summary of the invention:
The purpose of this utility model is for the pharmaceutical purpose pneumatic hydraulic diaphragm pump in no freon medicinal aerosol (HFA) process units, can realize the pressure of fed sheet of a media is accurately controlled, and has prolonged the use of diaphragm.
For achieving the above object, the technological scheme that the utility model is taked is: include upper pump casing, lower pump body, diaphragm etc.Upper pump casing is fixedlyed connected with lower pump body, between upper pump casing and lower pump body, diaphragm is housed, between upper pump casing and diaphragm, be provided with oil pocket, hydraulic oil is housed in the oil pocket, between lower pump body and diaphragm, be provided with medicinal liquid cavity, lower pump body is provided with soup import, the medicine liquid outlet that is communicated with medicinal liquid cavity, and the other end of upper pump casing is fixedlyed connected with the cylinder of production line, and the piston rod of cylinder puts in the oil pocket of upper pump casing and seal ring is housed.
During use, soup import, the medicine liquid outlet of lower pump body is communicated with the one-way valve of production line respectively.Handle the cylinder of production line, make piston rod to-and-fro motion in oil pocket, drive the hydraulic oil in the oil pocket, hydraulic oil drives the diaphragm to-and-fro motion, make soup advance medicinal liquid cavity, pump by medicine liquid outlet again, thereby realize providing soup with certain pressure to production line by the soup import of lower pump body.
In order to improve antiseptic power, the material of diaphragm adopts composite material (modified Teflon).The upper pump casing that contacts with soup, the material of lower pump body are resistant material, as stainless steel etc.
Because the utility model has adopted hydraulic oil as the intermediate medium that drives power, the compressibility of hydraulic oil changes little, makes the soup pressure stability of conveying, can accurately control; And hydraulic oil plays buffer function, and diaphragm is played a very good protection, and prolonged the working life of diaphragm.
Description of drawings:
Accompanying drawing is the utility model schematic representation.
Embodiment:
Accompanying drawing is an embodiment of the present utility model, includes upper pump casing 2, lower pump body 5, diaphragm 1 etc.Upper pump casing 2 is fixedlyed connected with lower pump body 5, between upper pump casing 2 and lower pump body 5, diaphragm 1 is housed, between upper pump casing 2 and diaphragm 1, be provided with oil pocket 3, in the oil pocket 3 hydraulic oil is housed, between lower pump body 5 and diaphragm 1, be provided with medicinal liquid cavity 9, lower pump body 5 is provided with soup import 6, the medicine liquid outlet 7 that is communicated with medicinal liquid cavity 9, and the other end of upper pump casing 2 is fixedlyed connected with the cylinder of production line, and the piston rod 4 of cylinder puts in the oil pocket 3 of upper pump casing 2 and seal ring 10 is housed.
In order to improve antiseptic power, the material of diaphragm 1 adopts composite material (modified Teflon).The upper pump casing 2 that contacts with soup, the material of lower pump body 5 are stainless steel.
During use, soup import 6, the medicine liquid outlet 7 of lower pump body 5 is communicated with the one-way valve 8 of production line respectively.Handle the cylinder of production line, make piston rod 4 to-and-fro motion in oil pocket 3, drive diaphragm 1 to-and-fro motion, make soup enter medicinal liquid cavity 9 by the soup import 6 of lower pump body 5 by the hydraulic oil in the oil pocket 3, pump by medicine liquid outlet 7 again, thereby realize providing soup with certain pressure to production line.
Because the utility model has adopted hydraulic oil as the intermediate medium that drives power, the compressibility of hydraulic oil Change littlely, therefore, the utlity model has the soup pressure stability that makes conveying, can accurately control; And hydraulic pressure Oil plays cushioning effect, and diaphragm is played a very good protection, and has prolonged the service life of diaphragm Etc. characteristics.
