Abstract
The utility model discloses a peristaltic pump, it includes a swing joint's a base and an upper cover, and this base is fixed on a motor, and this motor drives through a pivot and connects a bearing frame, and fixes a plurality of gyro wheels on the bearing frame, and a pump line passes through the gyro wheel is fixed into in the upper cover. The utility model discloses a peristaltic pump, lid and base installation are dismantled simply, conveniently change the pump line.
Description
Technical field
The utility model relates to a kind of peristaltic pump, more precisely is a kind of peristaltic pump of ease of assembly.
Background technique
Peristaltic pump is a kind of liquid transporting apparatus of may command flow velocity.Make through the repeated compression spring tube commonly that content moves towards certain orientation in the pipe, its flow velocity is determined with compression speed by the diameter of pipe, is mainly used in systems such as LC and perfusion.Fluid only contacts pump line, does not contact the pump housing, and precision is high; Repeatability, the high low-shearing force of steady state accuracy; Carry shear-sensitive, the ideal tools good airproof performance of erodibility high current body; Have good suction capacity, idle running can prevent that the backflow maintenance is simple; Valveless and Sealing; Has two-way equal flow volume delivery ability; Can any parts of pump not caused damage under the no liquid no load running situation; Can produce and reach 98% degree of vacuum; Do not have valve, mechanical seal and stuffing seal, just do not have these to produce the factor of revealing and safeguarding yet; Can carry solid, liquid or gas-liquid mixed phase fluid easily, contained solid diameter reaches pipe member internal diameter 40% in the permission fluid; Can carry various materials with grinding, burn into oxygen sensitivity characteristic and various food etc.; Only flexible pipe is for needing the parts of replacement, and it is very simple to change operation; Except that flexible pipe, institute's conveying products does not contact with any parts.But the peristaltic pump of present stage, structure are comparatively complicated, usually need dismantle whole peristaltic pump when needing to change pump line.
The model utility content
In order to solve the problem that above-mentioned existing technology exists, the purpose of the utility model is to propose a kind of peristaltic pump, and it can effectively solve the problems referred to above that existing technology exists.
For realizing above-mentioned purpose, the utility model can solve through following technological scheme:
A kind of peristaltic pump, it comprises a base and a loam cake of flexible connection, and this base is fixed on one and reaches, and this motor drives through a rotating shaft and connects a bearing support, and fixing some rollers on the bearing support, and a pump line is fixed in the said loam cake through said roller.
As the further technical characteristics of the utility model, said pump line two ends are respectively through a joint and pipeline connection.
As the further technical characteristics of the utility model, said bearing support is an I shape seat.
As the further technical characteristics of the utility model, cover on said and be provided with some first spacing preiections, this first spacing preiection is provided with a limit stoper; And said base is provided with second spacing preiection of some and said first spacing preiection coupling.
As the further technical characteristics of the utility model, said roller is three.
Since adopt above technological scheme, a kind of peristaltic pump of the utility model, and lid and base installing/dismounting are simple, are convenient for changing pump line.
Description of drawings
Fig. 1 is the blast structural representation of the utility model.
Fig. 2 is structure second schematic representation of the utility model.
Embodiment
Below in conjunction with embodiment, further set forth the utility model:
As shown in the figure, a kind of peristaltic pump, it comprises a base 6 and a loam cake 1, and this loam cake 1 flexibly connects with base 6, and base 6 is fixedly connected on the motor 7.The rotating shaft of motor 7 connects drive and is located at the bearing support 2 in the loam cake 1, and this bearing support 2 is an I oblique crank Z bearing, fixing some rollers 3 on it.One pump line 4 is through roller 3 spacing being fixed in the loam cake, and pump line 4 two ends are through two joints 5 and other pipeline connections, and two joints 5 are fixed on said loam cake 1 and the base 6.In the present embodiment, roller 3 is provided with three, and it evenly distributes, and according to demand, the number of roller also can be for a plurality of.
Loam cake 1 is provided with one first spacing preiection 9; Base 6 is provided with second spacing preiection 10 that is complementary, when loam cake 1 and base 6 needs fixedly, with first spacing preiection 9 and second spacing preiection, 10 alignings; Then with loam cake 1 relative base 6 rotations; And loam cake 1 is provided with a limit stoper 8, can carry out spacingly to loam cake 1 and base 6 through this limit stoper 8, guarantees that loam cake 1 and base 6 forward corresponding position in counterrotating process.
Thereby motor 7 drives rotating shaft and drives bearing support 2, thereby drives roller 3 fixing on it, and roller 3 can produce the power of an extruding to the liquid in the pump line 4 in rotation process, thereby drives flowing of liquid.
Loam cake 1 is provided with the convexity with two joints, 5 couplings, and base 6 and loam cake 1 matched position place are provided with the convexity of coupling, and when base 6 and loam cake 1 fixed connection, the spacing cavity of formation can be fixed two joints 5.When the peristaltic pump of the utility model was installed, base 6 was fixed on the motor 7.Roller 3 is fixed on the said bearing support 2; Then pump line 4 two ends are connected with joint 5; Pump line 4 is wrapped in the outside of said roller 3, and bearing support 2 and pump line 4 fixed limits that will be fixed with roller 3 then are in loam cake 1, and two joints 5 are fixed on the loam cake 1; Bearing support 2 is passed in the rotating shaft of motor 7, then that loam cake 1 is fixing with base 6.
Because the working life of pump line 4 is limited, after using certain number of times damage, can conveniently loam cake 1 be taken off, in time change pump line.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
