Abstract
The utility model provides a protection mechanism of a flexible hose of a peristaltic pump. The mechanism comprises a pump body, a rotor roller assembly, and the flexible hose, and is characterized in that the pump body is fixed with a flexile isolation strip positioned between the rollers of the rotor roller assembly and the rolling joint face of the flexible hose. The protection mechanism of the flexible hose of the peristaltic pump is positioned between the flexible hose and the roller, when each roller rotates along with the rotor, the generated rolling friction is only applied to the flexible isolation strip, and the flexible hose only bears the rolling pressure. Obviously, the protection mechanism of the flexible hose can stand over or avoid the wear deformation of the flexible hose, thereby facilitating the repeatability precision and stability of the peristaltic pump. The utility model has the outstanding advantages of simple structure and obvious protection effect, and is suitable for the peristaltic pumps of various purposes and types.
Description
Technical field
The utility model belongs to peristaltic pump, particularly relates to the protection mechanism of peristaltic pump elastic hose.
Background technique
Peristaltic pump claims peristaltic pump again, is made up of pump head, driver, and pump head comprises the pump housing, briquetting, rotor roller assembly and elastic hose.The rotor rotation is alternately pushed roller and is discharged the conveying that elastic hose is realized fluid.
Elastic hose is the parts of the only contacting fluid of peristaltic pump, difference according to fluid properties, peristaltic pump to the bearing capacity of elastic hose, adsorptivity, temperature tolerance, anti-aging, swelling, performance such as corrosion-resistant can not have corresponding requirements respectively, but the fluid properties of no matter being carried why not have with, then be anti-extruding and wear resistance to the basic demand of elastic hose.
Although there is direct relation in the flexible life-span of elastic hose with cast, tubing, pump head form, motion speed, elastic hose is a well known fact because of abrasion deformation becomes easily damaged parts.
Summary of the invention
The utility model is to provide a kind of protection mechanism that can delay or avoid the peristaltic pump elastic hose of its abrasion deformation in order to solve elastic hose because of the technical problem that abrasion deformation becomes easily damaged parts.
The utility model is taked following technological scheme in order to solve the problems of the technologies described above: the protection mechanism of peristaltic pump elastic hose is made up of the pump housing, rotor roller assembly and elastic hose; feature is that the pump housing is fixed with the pliable and tough isolation zone between the roller of rotor roller assembly and elastic hose rolling mating face.
The utility model can also be taked following technical measures:
Described pliable and tough isolation zone width is suitable with roller length.
Described pliable and tough isolation zone thickness is not more than 2mm.
The pump housing of described rotor roller assembly both sides is provided with the deck that clamps fixing two ends, pliable and tough isolation zone respectively.
Described deck is made of the eccentric pinch roller and the pressing plate of band handle, and end, pliable and tough isolation zone is between eccentric pinch roller and baffle plate.
Described pump housing bottom surface is arranged with slotted eye, and the position of two slotted eyes is corresponding with rotor roller assembly both sides, and draw from corresponding slotted eye respectively at two ends, pliable and tough isolation zone, and pump housing bottom surface is provided with the pressing plate of fixing end, pliable and tough isolation zone respectively.
The beneficial effects of the utility model and advantage are: pliable and tough isolation zone is between elastic hose and roller in the protection mechanism of this elastic hose; the force of rolling friction that produces during with rotor motion when each roller only acts on pliable and tough isolation zone, and elastic hose only bears rolling pressure.The protection mechanism of apparent this elastic hose can delay or avoid the abrasion deformation of elastic hose, helps the repeatability and the stability of peristaltic pump.The utlity model has simple in structure, the outstanding advantage of protection outstanding effect, be applicable to the peristaltic pump of various uses and type.
