Description
Technical field
The present invention relates to a kind of miniature peristaltic pump, belong to minisize fluid pump technical field, for analysis, filling, environment friendly system, move towards assigned direction by the content in the repeated compression spring tube.
Background technique
The peristaltic pump working principle resembles with flexible pipe that is full of fluid of finger pinching, along with pointing sliding tube inner fluid forward, moves forward, and 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.As with two finger pinching flexible pipes, along with the movement of finger, form negative pressure in pipe, liquid flows thereupon.Peristaltic pump is exactly one section pump line formation " pillow " shape fluid between two transfer roller.The volume of " pillow " depends on the internal diameter of pump line and the geometric properties of rotor.Often the turn around product of these three parameters of number of " pillow " of generation of the rotating speed that flow depends on pump head and size, the rotor of " pillow ".The size of " pillow " is generally constant (except during the king-sized fluid of pumping viscosity).Take the identical pump of root diameter to compare, produce the pump of large " pillow " volume, its rotor carried fluid volume that often turns around is also larger, but the pulsation degree of generation is also larger.This situation to the film valve is similar.And producing the pump of less " pillow " volume, its rotor carried fluid volume that often turns around is also less; And little " pillow " formed rapidly, continuously makes flowing of fluid comparatively steady.This situation to gear pump is similar.
Be the extrusion pump cast in current published technology, because no matter whether peristaltic pump moves in instrument and equipment, roller is all under the state of extruding pump line, when especially peristaltic pump does not move for a long time, roller is all the time on a motionless point that is pressed in pump line, and pump line is elastomer, long-time extruding increases its internal stress, local elasticity's variation, gently cause the pump line permanent deformation to affect the peristaltic pump precision, heavy cause between pump line mutually being bonded together peristaltic pump was lost efficacy.Thereby whole system can't be operated, and general peristaltic pump does not move, and pump line will be produced gross distortion in 1 month by roller compression, compresses and will produce adhesion phenomenon 1 ~ March.Pump line is out of shape and adhesion, has hindered greatly popularization and the serviceability of peristaltic pump, according to the peristaltic pump inefficacy of statistics 80%, is relevant with pump line.
Summary of the invention
Technical problem to be solved by this invention is the defect that overcomes prior art, and a kind of miniature peristaltic pump is provided, and it can effectively loosen pump line under off working state, avoids not using the phenomenon that causes the pump line adhesion to be lost efficacy for a long time, increases its working life.
In order to solve the problems of the technologies described above, technological scheme of the present invention is: a kind of miniature peristaltic pump, it comprises pump bracket, the pump housing, connector housing, pump line, pump impeller, roll wheel assembly, but the motor of cover plate and clockwise and anticlockwise, the pump housing and connector housing are installed on pump bracket, the pump housing is fixedly connected with cover plate, and pump body is provided with don't manage holding cavity, roll wheel assembly has at least two rollers, the motor shaft of pump impeller and motor is flexibly connected, be provided with the rail slot coordinated with corresponding roller on pump impeller, and the distance between the axle center of each rail slot and pump impeller is reduced to centre gradually by the two ends of rail slot, roll wheel assembly is arranged on pump impeller and an end of roller interts in corresponding rail slot, pump line is contained in the pump line holding cavity, and around the outside that is arranged in roll wheel assembly, the two ends of pump line are connected on connector housing after all stretching out the pump housing.
Further, described pump impeller is made into integration by track cell body, connection axis body and driving body, the track cell body is connected to driving body the two ends that are connected axis body, described rail slot is opened on the track cell body, be provided with the butt profile matched with corresponding rail slot on described driving body, and the two ends of butt profile are provided with roller and drive bearing surface, and the other end of roller is connected on corresponding butt profile.
Further, the roller of described roll wheel assembly has two, and described rail slot also has two.
After having adopted technique scheme, this peristaltic pump is when normal operation, roller all is positioned at the end of rail slot, motor action, the rotation of drive pump impeller, thereby drive the roll wheel assembly rotation, make roll wheel assembly to the hocket extruding and discharge pumping fluid of the pump line of pump, when peristaltic pump is prepared to quit work, by motor moved the certain angle of rear counterrotating control the displacement of roller in rail slot make its from the extruding pump line position (being an end or the other end of rail slot) move the position (being the middle part of rail slot) that setting is loosened, in roller displacement process, roller shrinks gradually to the center of pump impeller, make it not push pump line, auto-closing and the function of opening pump line have been realized, make peristaltic pump in the situation that stop not moving, do not push pump line, make pump line can recover elasticity, thereby greatly increase its life-span and reduce adhesion, fundamentally having solved peristaltic pump needs often to safeguard, the problem that pump line often need to be changed, it is non-maintaining that the present invention really accomplishes peristaltic pump, exempt to unpick and wash, expanded greatly the using scope of peristaltic pump.
