Water displacement of the gas peristaltic pump is improved, a multi-cavity crossed ceaseless liquid supply function is realized, and the multi-cavity gas peristaltic pump is simple in structure and convenient to maintain.
Description
Technical field
The invention belongs to peristaltic-type pump arrangement technical field, be specifically related to a kind of multi-chamber gas peristaltic pump.
Background technique
Peristaltic pump, just as with flexible pipe that is full of fluid of finger pinching, moves forward along with pointing sliding tube inner fluid forward.Peristaltic pump is also that this principle has just replaced finger by roller.By hocket extruding and discharge pumping fluid of the elasticity delivery hose to pump.Just as with two finger pinching flexible pipes, along with the movement of finger, in pipe, form negative pressure, liquid flows thereupon.The shortcoming of traditional peristaltic pump technology is, complex structure is manufactured difficulty, and rate of fault is high, and maintenance is inconvenient, and mechanical wear amount is large, and working life is short etc., and there will be the discharge opeing of discontinuity, thereby makes lifting rate lower.
Summary of the invention
The object of the invention is to solve above-described technical problem, a kind of multi-chamber gas peristaltic pump is provided, its technological scheme is as follows:
A kind of multi-chamber gas peristaltic pump, it is characterized in that, described multi-chamber gas peristaltic pump comprises the pump housing and some silicone tubes, in the described pump housing, be provided with several cavitys, described silicone tube is arranged on the pump housing through after cavity, and described some silicone tubes are corresponding one by one with some cavitys, and the place, two ends near the pump housing on described silicone tube is provided with import one-way valve and outlet one-way valve, on the described pump housing, offer the through hole that several communicate with cavity, described through hole is corresponding one by one with cavity.
Optimal way is, the described pump housing comprises housing and be arranged at the end cap at housing two ends, and described end cap and housing form some cavitys.
Multi-chamber gas peristaltic pump provided by the invention, its beneficial effect is:
In the pump housing of the present invention, be provided with some cavitys, described silicone tube is arranged on the pump housing through after cavity.The effect of cavity is mainly to provide the site space of an extruding silicone tube, and cavity makes pressurized air enter into cavity after being connected with air compressor can push silicone tube, thereby the liquid in silicone tube is pushed away.And the object that is provided with some cavitys is because the discharge opeing cycle of single cavity is oversize less with lifting rate, there will be the discharge opeing of discontinuity, a plurality of cavitys can shorten drainage period, realize the continual silicone tube that pushes of different cavity connectivities in one-period and carry out discharge opeing, strengthened lifting rate.Two ends place near the pump housing on silicone tube is provided with import one-way valve and outlet one-way valve, is in order to control feed liquor and fluid is used.
The pump housing of the present invention comprises housing and the end cap that is arranged at housing two ends, and described end cap and housing form some cavitys.End cap to be arranged so that silicone tube passes these installation steps of the pump housing more convenient.As long as first end cap is opened, then silicone tube, through entering in cavity from an end cap, then passes just passablely from another end cap, makes its installation easier.And make maintenance also more convenient.
The invention enables gas peristaltic pump to improve water displacement, realize Multicarity and intersect uninterrupted feed flow function, and simple in structure easy to maintenance.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Embodiment
Below in conjunction with Fig. 1, illustrate embodiment:
A kind of multi-chamber gas peristaltic pump, described multi-chamber gas peristaltic pump comprises the pump housing 1 and some silicone tubes 2, in the described pump housing 1, be provided with several cavitys 3, described silicone tube 2 is arranged on the pump housing 1 through after cavity 3, described some silicone tubes 2 are corresponding one by one with some cavitys 3, place, two ends near the pump housing 1 on described silicone tube 2 is provided with import one-way valve 4 and outlet one-way valve 5, on the described pump housing 1, offer the through hole 6 that several communicate with cavity 3, described through hole 6 is corresponding one by one with cavity 3.The described pump housing 1 comprises housing 7 and is arranged at the end cap 8 at housing 7 two ends, described end cap 8 and the some cavitys 3 of housing 7 formation.
The present invention first one end of 3 silicone tubes through after an end cap of the pump housing, 3 silicone tubes enter into one to one in 3 cavitys separately, then from another end cap, pass.The housing seal of two end cap and the pump housing, two end cap and housing form 3 airtight cavitys.The place, two ends being positioned on each silicone tube near the pump housing is provided with import one-way valve and outlet one-way valve.On the pump housing, above 3 cavitys, locate to offer and offered 3 through holes, through hole and cavity are corresponding and communicate with cavity one by one.
When in use, 3 through holes on the pump housing are connected with 3 connecting tubes, and one end of every connecting tube communicates with cavity, and the other end of 3 connecting tubes is connected with solenoid valve jointly.Solenoid valve communicates with air compressor by connecting tube.And solenoid valve is also connected with timing controller and power supply.
First timing controller is set the cycle time that opens and closes solenoid valve.One end that 3 silicone tubes are provided with to import one-way valve is put in liquid, then switches on power.Air compressor work, timing controller and electromagnetic valve arrive compressed air delivery in first cavity, thereby make pressurized air push the silicone tube in first cavity.Liquid in silicone tube is squeezed out to silicone tube through outlet one-way valve.Follow timing controller and electromagnetic valve in compressed air delivery to the second cavity, thereby make the silicone tube in second cavity of pressurized air extruding, the liquid in silicone tube is squeezed out to silicone tube through outlet one-way valve.Last timing controller and electromagnetic valve be in three cavitys of compressed air delivery to the, thereby make the silicone tube in the 3rd cavity of pressurized air extruding, and the liquid in silicone tube is squeezed out to silicone tube through outlet one-way valve.Now, first cavity is interior because pressurized air does not enter, thereby makes the silicone tube reinstatement in first cavity.Silicone tube in the process of reinstatement constantly through import one-way valve imbitition in silicone tube.After completing the extruding of the 3rd cavity, the silicone tube in first and second cavity has restored to the original state that imbibition completes and can carry out next time capable of discharging liquid by extruding.Circulation and so forth, intersects continual feed flow thereby realized multi-chamber, has improved water displacement.
Working principle of the present invention is: the principle of Pneumatic creeping pump is to utilize pressurized air to make the silicone tube in one of them cavity be squeezed and deform within the time of some/mono-operation cycle, mineralization pressure in silicone tube, utilize the liquid in the emptying silicone tube of outlet one-way valve simultaneously, in the time of remaining operation cycle, because pressurized air does not enter this cavity, so silicone tube recovers shape, in pipe, form negative pressure, utilize import one-way valve that liquid is sucked in silicone tube rapidly simultaneously.So circulation reaches the object of carrying liquid.
End cap of the present invention has adopted withstand voltage material to make, in order to guarantee to have good pressure extrusion silicone tube in cavity, so when silicone tube is arranged in cavity, wall and the spacing between silicone tube of cavity are the smaller the better.
