Abstract

The utility model discloses a peristaltic pump which is used in the precision fluid transportation field and comprises a pump pipe, a pump head, and a driver. The pump pipe is the part which directly contacts with fluid. The pump head is the part which squeezes the pump pie and makes the pump pipe create vacuum continuously. The driver is the part which drives internal mechanisms of the pump head to rotate. The pump pipe is made of highly-tear-resistant and high-function rubber materials. All the components of the pump head can be manufactured through mechanical cutting technologies and does not need die-opening manufacturing. The driver is internally provided with a stepping motor, a control IC chip, and a drive IC chip. By employing the aforementioned chips, the precision transportation and digital control of the fluid can be realized. The novel peristaltic pump is characterized by being high in cleanliness, high in precision, easy to clean, little in cutting, and easy to maintain.

As further improvement of the utility model: described pump head has five kinds of structural types, and these five kinds of its members of structural type all adopt the machine cut processes to form, needn't the die sinking manufacturing, be fit to very much single-piece and small lot batch manufacture, and flexibly selection.

As further improvement of the utility model: described peristaltic pump structure form can adopt circular cover to fix, the right and left fluting, and pump line is made from the mode that passes between groove.

As further improvement of the utility model: described peristaltic pump structure form can adopt the semicircle gland to fix, and the mode that pump line passes from the below is made.

As further improvement of the utility model: described peristaltic pump structure form is can employing activity gland removable, and two screws cross movable gland, and pump line is made from the mode that the right and left penetrates and passes.

As further improvement of the utility model: described peristaltic pump structure form is can employing activity gland removable, and a screw is pushed down gland from top, and pump line is made from the mode that the right and left penetrates and passes.

As further improvement of the utility model: described peristaltic pump structure form can adopt easy dress gland by fixing with hinge-coupled, can open, and pump line is made from the mode that the right and left penetrates and passes.

As further improvement of the utility model: the pcb board two cores unification of described internal drive, built-in control IC chip and driving IC chip; Realize the accurate conveying of fluid by the control of chip precision digital.

Compared with prior art, the beneficial effects of the utility model are: after using the utility model, pump head production needn't die sinking and arbitrarily selection, is fit to very much carry out nonstandard customization by the special type requirement suitable single-piece and small lot batch manufacture.When selecting stainless steel or other special materials, and when guaranteeing processing and assembly precision, can produce the extraordinary peristaltic pump fluid delivery system that precision is high especially, performance is stable especially, the life-span is long especially.
