Abstract
The invention provides a method for protecting an elastic hose of a peristaltic pump. A pliable isolation strip is arranged between rolling wheels of a rotor rolling wheel assembly of the peristaltic pump and a rolling joint surface of the elastic hose; the two ends of the pliable isolation strip are fixed; a strip body produces a mobile wave crest along with the rolling wheels conducting circumferential rotation; and the wave crest is contacted with the elastic hose and moves in the axial direction of the elastic hose. According to the method for protecting the elastic hose of the peristaltic pump, the pliable isolation strip is positioned between the elastic hose and the rolling wheels, the rolling friction force, which is produced when the rolling wheels move along with a rotor, only acts on the pliable isolation strip, and the elastic hose only bears rolling pressure. Obviously, by using the method, the abrasion deformation of the elastic hose can be delayed or avoided, thereby facilitating the repeat accuracy and the stability of the peristaltic pump. The method has the outstanding advantages of simple structure and obvious protection effect, and is suitable for peristaltic pumps for various purposes and of various types.
Description
Technical field
Workability is good owing to PEEK has temperature flowing, and the very high characteristics of heat decomposition temperature can adopt multiple processing mode: injection moulding, extruding and moulding, compression molding and melt spinning etc.
The invention belongs to peristaltic pump, particularly relate to the guard method 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 present invention provides a kind of guard method 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 present invention is in order to solve the problems of the technologies described above the following method of taking: between the roller of peristaltic pump rotor roller assembly and elastic hose rolling mating face pliable and tough isolation zone is set, the two ends of described pliable and tough isolation zone are fixed, and each roller that belt body rotates with circumference produces the crest that moves, and this crest contacts with elastic hose and moves along the axial direction of elastic hose.
The present invention can also take following technical measures:
The pump housing is fixed at the two ends of described pliable and tough isolation zone.
Described pliable and tough isolation zone width and roller equal in length.
Described pliable and tough isolation zone thickness is not more than 2mm.
The material of described pliable and tough isolation zone is teflon or polyether-ether-ketone or poly-third ethene.
Described rotor roller assembly is provided with the multichannel roller, between the rolling mating face of the roller of each passage and pairing elastic hose pliable and tough isolation zone is set all.
Beneficial effect of the present invention and advantage are: pliable and tough isolation zone is between elastic hose and roller in the guard method of this peristaltic pump 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.Apparent this method can delay or avoid the abrasion deformation of elastic hose, helps the repeatability and the stability of peristaltic pump.That this method has is simple in structure, the outstanding advantage of protection outstanding effect, is applicable to the peristaltic pump of various uses and type.
Description of drawings
Accompanying drawing 1 is one of structural principle schematic representation of the present invention.
Accompanying drawing 2 is two of structural principle schematic representation of the present invention.
Accompanying drawing 3 is embodiment of the invention structure partial generalized sections.
Accompanying drawing 4 is that Fig. 3 A is to partial cutaway schematic.
Number in the figure: 1 pliable and tough isolation zone, 2 rotor roller assemblies, 2-1 roller, 3 pump housings, 4 elastic hoses, 5 pressure heads, 6 pressing plates.
Embodiment
Further specify the present invention below in conjunction with embodiment and accompanying drawing thereof.
As shown in Figure 1, 2, between the roller 2-1 of peristaltic pump rotor roller assembly 2 and elastic hose 4 rolling mating faces pliable and tough isolation zone 1 is set, the two ends of pliable and tough isolation zone are fixed.
Pliable and tough isolation zone 1 shown in Fig. 1,2 produces the crest that moves with each roller of arrow i bearing circle revolution, the roller a of Fig. 1 contacts with pliable and tough isolation zone 1, this contacting point produces the crest crest, when each roller that circumference rotates turns to Fig. 2 position, roller a produces crest with through shifting out, what come subsequently will be the crest that roller c produces, treat that crest that roller c produces shifts out rear roller b and will produce another crest, the crest that each roller produces successively contacts with elastic hose and moves along the axial direction of elastic hose.
The pump housing is fixed at the two ends of pliable and tough isolation zone, and its mode of execution is shown in Fig. 3,4.
Between the roller 2-1 of Fig. 3,4 rotor roller assemblies 2 and the elastic hose 4 rolling mating faces pliable and tough isolation zone 1 is set, its two ends are individually fixed in the pressing plate 6 of the pump housing 3 bottom surfaces by the screw tightening.Specifically, the pump housing 3 bottom surfaces are arranged with slotted eye, and the position of two slotted eyes is corresponding with rotor roller assembly 2 both sides, and pressing plate 6 is drawn and be individually fixed in 1 two ends, pliable and tough isolation zone from corresponding slotted eye respectively.
Embodiment's flexible isolating bandwidth and roller 2-1 equal in length, thickness be not more than 2mm all can, with best below the 1mm.The material of embodiment's flexible isolating band can be teflon or polyether-ether-ketone or poly-third ethene.
As shown in Figure 3, elastic hose 4 moves down and can contact with pliable and tough isolation zone 1 with pressure head 5.
Embodiment is the single channel miniature peristaltic pump, and embodiment's structure is equally applicable to multi-channel peristaltic pump, promptly between the rolling mating face of the roller of each passage of rotor roller assembly and pairing elastic hose pliable and tough isolation zone is set all.
