Abstract
The utility model discloses an alternately-pressing peristaltic pump. The peristaltic pump is characterized in that a plurality of rolling shafts are evenly arranged on the outer circumferences of rolling shaft discs, and when the multiple rolling shafts pass through the positions close to pump covers in the rotating processes of the rolling shaft discs, Y-shaped hoses can be pressed to generate pulses. The rolling shafts with position differences on the two rolling shaft discs alternately press the Y-shaped hoses, the pulses which are two times the pulses of a common single peristaltic pump are generated, liquid is even in pulse and stable in flow speed in the filling process, and the liquid split charging accuracy is improved.
Description
Technical field
The utility model belongs to mechanical pump field, is specifically related to a kind of peristaltic pump that alternately pushes pipeline conveying liquid body.

Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of equipment volume little, improves pulse number by alternately pushing, and improves the peristaltic pump of packing precision.
The technical solution of the utility model is achieved in that the alternately peristaltic pump of extruding, it is characterized in that: comprise the pump housing and pump cover, in the described pump housing, be provided with adjacent two coaxial roller bearing dishes, evenly distributedly on the excircle of described roller bearing dish be provided with at least five roller bearings, the identical and position of roller bearing quantity on described two roller bearing dishes has deviation; The both sides of the described pump housing have multiple skewed slots, one side is one, opposite side is two, described pump cover covers on the pump housing, described skewed slot coordinates formation hole structure with pump cover, described hole structure is inserted in " Y " shape flexible pipe, and the spatial joint clearance that described pump cover and roller bearing form is less than the external diameter of described " Y " shape flexible pipe; When two roller bearing dishes rotate, two groups of roller bearings push " Y " shape flexible pipe because positional deviation has replacing of priority.
Improve as one, " Y " shape flexible pipe comprises two supplying tubes and an output tube, described supplying tube and output tube formation " Y " shape that communicates, and described two supplying tubes contact cooperation with a roller bearing dish respectively in the pump housing.
Improve as one, the external diameter of " Y " shape flexible pipe is 8-10mm, and the spatial joint clearance that described pump cover and roller bearing form is 5-7mm.
Improve as one, on each roller bearing dish, the quantity of roller bearing is six, and on two roller bearing dishes, the differential seat angle of roller bearing and roller bearing is 30 degree.
Improve as one, also include pump support, in described pump support, be provided with power supply, two peristaltic pumps are set on pump support, described two peristaltic pumps connect respectively power supply.
The beneficial effects of the utility model: when multiple roller bearings of evenly distributed setting pass through the position of close pump cover in rotary course on the excircle of roller bearing dish, can push and produce pulse " Y " shape flexible pipe; Have extruding " Y " the shape flexible pipe that the roller bearing on two roller bearing dishes of positional deviation replaces, produce the pulse of twice compared with common single peristaltic pump, realized liquid pulse in pouring process even, flow velocity is steady, has improved the packing precision of liquid.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model peristaltic pump.
Fig. 2 is the structural representation of the utility model " Y " shape flexible pipe.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1, 2, be the specific embodiment of the utility model peristaltic pump.This embodiment comprises the pump housing 1 and pump cover 2, is provided with adjacent two coaxial roller bearing dishes 3 in the pump housing 1, and on the excircle of roller bearing dish 3, the evenly distributed identical and position of roller bearing 4 quantity on 4, two roller bearing dishes 3 of at least five roller bearings that is provided with has deviation; It is one that the both sides of the pump housing 1 have multiple skewed slot 5, one sides, and opposite side is two, pump cover 2 covers on the pump housing 1, skewed slot 5 coordinates formation hole structure with pump cover 2, hole structure is inserted in " Y " shape flexible pipe 6, and the spatial joint clearance that pump cover 2 and roller bearing 4 form is less than the external diameter of described " Y " shape flexible pipe 6; When two roller bearing dishes 3 rotate, two groups of roller bearings 4 push " Y " shape flexible pipe 6 because positional deviation has replacing of priority.When multiple roller bearings 4 of the utility model evenly distributed setting on the excircle of roller bearing dish 3 pass through near the position of pump cover 2 in rotary course, can push and produce pulse " Y " shape flexible pipe 6; Have extruding " Y " the shape flexible pipe that the roller bearing 4 on two roller bearing dishes 3 of positional deviation replaces, produce the pulse of twice compared with common single peristaltic pump, realized liquid pulse in pouring process even, flow velocity is steady, has improved the packing precision of liquid.
As the improved embodiment of one, " Y " shape flexible pipe 6 comprises two supplying tubes 61 and an output tube 62, supplying tube 61 and output tube 62 formation " Y " shape that communicates, and two supplying tubes 61 contact cooperation with a roller bearing dish 3 respectively in the pump housing 1.The structure of corresponding two roller bearing dishes 3, design two supplying tubes 61, a roller bearing dish 3 pushes a supplying tube 61, and gather to output tube 62 and outwards carry, reaching roller bearing dish 3 rotates a circle and can carry out to solution in " Y " shape flexible pipe 6 the extruding pulsatile effect of twice, in infusion process, precision improves, flow speed stability.
As the improved embodiment of one, the external diameter of " Y " shape flexible pipe 6 is 8-10mm, and pump cover 2 is 5-7mm with the spatial joint clearance that roller bearing 4 forms.Above size design can ensure " Y " shape flexible pipe 6 pulse better effects if in the time being pushed by pump cover 2 and roller bearing 4.
As the improved embodiment of one, on each roller bearing dish 3, the quantity of roller bearing 4 is six, and on two roller bearing dishes 3, roller bearing 4 is 30 degree with the differential seat angle of roller bearing 4.Adopt the roller bearing 4 of six group, and the differential seat angle of two groups of roller bearings 4 is 30 degree, realizes every 30 degree " Y " shape flexible pipe 6 is produced to pulsatile once, make the steadily fluid of solution in " Y " shape flexible pipe 6.
