Description
Technical field
The present invention relates to field of electromechanical equipment, particularly a kind of volume pump installation.
Background technology
At present in field of electromechanical equipment, membrane pump is one of widely used volume pump installation.Existing barrier film
Pump is mainly made up of cylinder body, barrier film and drive mechanism, and wherein, working media can be effectively isolated by barrier film with destination media.Every
The operation principle of membrane pump mainly drives reciprocating motion of the barrier film in cylinder body by drive mechanism, to change exterior
The fluid flow of destination media, so that complete the pumping to destination media.
However, the membrane shape of prior art septation pump is essentially lamellar, its stroke is little, and jig frequency is high.Barrier film this
On the one hand structure can cause barrier film operation when destination media is pumped not steady enough；On the other hand, in prior art, working media
During closed cycle, it is necessary to which pressure detecting and the compensation mechanism to working media is set, and otherwise barrier film is easily damaged, thus be increased
The probability of failure of membrane pump and manufacturing cost；Meanwhile, the high jig frequency of existing membrane pump is easily caused and is carried into, valve and changement
Front damage, reduces the service life of membrane pump.
For the problem that above-mentioned technology is present, wish in the art to seek a kind of with Long travel, low jig frequency new
Volume pump installation, makes volume pump operation more stably while reducing production and management cost.
Content of the invention
The invention provides a kind of volume pump installation, including cylinder body, the retractable sack being arranged in cylinder body, and is used for driving
The flexible drive mechanism of retractable sack.Wherein, formed between the inner surface of the outer surface and cylinder body of retractable sack and be situated between for conveying target
The first area of matter, the inner surface of retractable sack connect to be formed for circulating the second area of working media with drive mechanism.
According to the present invention, retractable sack can will be completely isolated to working media and destination media, and directly driven by drive mechanism
Dynamic working media completes retractable sack to retractable sack effect and stretches, so that the volume outside retractable sack changes to complete
Pumping procedure.Wherein, the circulation of working media drives retractable sack to stretch makes the volume of second area change, simultaneous retractable capsule
Destination media of the extension contraposition in its outside first area acted on, make the volume of first area change, from
And complete the pumping to destination media.Retractable sack rather than of the prior art barrier film have been used in the present invention.According to the present invention,
