This hose pump hose the anti scuffing, anti tear and kick -back in the index have apparent an improvement for traditional flexible rubber hose, the 2 -3 that life can reach the conventional hose life -span doubly is particularly useful for in the hose pump application abominable ambient condition under.
Description
Technical field
The utility model relates to a kind of Material pipeline, specifically refers to a kind of high anti-abrasion hose of hose pump.
Background technique
Peristaltic pump belongs to the category of peristaltic pump, what its artificer and user primarily valued is, and it carries the ability of strong abrasiveness medium, its valveless, without sealing, unique parts with medium contact is the inner chamber of rubber hose, the rotor of compression flexible pipe is totally independent of outside medium, therefore, the core component of peristaltic pump is exactly flexible pipe, can determine peristaltic pump in working life of flexible pipe the key point of precise and stable running, the rubber hose major defect of current domestic production shows as: one, rubber hose internal layer erosion resistance is poor, especially under being applied in exceedingly odious chemical corrosion condition, internal layer easily corrodes and comes off, cause framework layer breakage and then cause whole flexible pipe to scrap, two, the rebound elasticity of flexible pipe and tear strength poor, when being applied to hyperbaric environment, the easy dilatancy of flexible pipe, there is bag-like projection or directly causes hose fracture in local.
Summary of the invention
For solving the technical problem existing for existing hose of hose pump, the utility model, by the improvement to flexible pipe internal layer and framework layer, provides a kind of high anti-abrasion hose of hose pump.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is: high anti-abrasion hose of hose pump, its tube wall is made up of inner glue layer, framework layer and outer glue-line from inside to outside successively, it is characterized in that: the internal surface of described inner glue layer is provided with polytetrafluoroethylene floor, described polytetrafluoroethylene floor turns over bag to the outer glue-line of flexible pipe by body two ends, and turning over packet length is 50-100mm.
Further, described teflon layer thickness is 0.15-0.20mm.
Further, described framework layer is worked out by organizine and tram, and described organizine refers to the establishment silk around flexible pipe direction; Described tram refers to the establishment silk along flexible pipe axial direction, and described tram adopts nylon wire; Described organizine adopts nylon wire and steel wire to be spaced and forms, and the spacing between described steel wire equals the spacing between 8-15 nylon wire.
The beneficial effects of the utility model are: this hose of hose pump increases significantly relative to traditional rubber hose tool in anti-abrasion, tear-proof and resilience index, the 2-3 that can reach the Conventional hose life-span working life doubly, is particularly useful in the peristaltic pump application under severe environmental conditions.
Accompanying drawing explanation
Accompanying drawing 1 is structure sectional view of the present utility model.
Accompanying drawing 2 is the structural representation of framework layer.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, high anti-abrasion hose of hose pump, its tube wall is made up of inner glue layer 1, framework layer 2 and outer glue-line 3 from inside to outside successively, and this structure is the structure of hose of hose pump common at present.
For improve current peristaltic pump use the performance of flexible pipe, the utility model on the basis of existing flexible pipe, do following improvement.
One, for increasing the erosion resistance of inner glue layer 1, as shown in Figure 1, the internal surface of inner glue layer 1 is provided with polytetrafluoroethylene floor 4.As shown in Figure 1, for preventing severe corrosive material to the corrosion of flexible pipe two ends end face, polytetrafluoroethylene floor 4 turns over bag to the outer glue-line of flexible pipe by body two ends, and turning over packet length is 50-100mm.
Polytetrafluoroethylmaterial material is commonly called as King, is generally called " non-sticking lining " or " material easy to clean, this material has the feature of antiacid alkali resistant, anti-various organic solvent, is dissolved in all solvents hardly.Meanwhile, teflon has resistant to elevated temperatures feature, and friction factor is extremely low.Lay polytetrafluoroethylene floor on the inner glue layer surface of flexible pipe can completely cut off flexible pipe inner glue layer and contact with strong acid-base, the direct of extensive chemical Corrosive Materia the erosion damage caused rubber at work, greatly reduce the friction factor of hose inner wall simultaneously, reduce material to the impact of hose inner wall, the erosion resistance of flexible pipe and heat-resisting quantity are greatly improved.During making, the thickness general warranty of polytetrafluoroethylene floor 4 can ensure the performance of flexible pipe between 0.15-0.20mm.
Two, for increasing the rebound elasticity of flexible pipe simultaneously in order to ensure the pliability of flexible pipe, in the present embodiment further improvement has been done to framework layer 2.As shown in Figure 2, framework layer 2 is worked out by organizine 21 and tram 22, organizine 21 refers to the establishment silk around flexible pipe direction, tram 22 refers to the establishment silk along flexible pipe axial direction, and as shown in Figure 2, tram 22 adopts nylon wire material to make, and the material of organizine 21 comprises nylon wire 211 and steel wire 212, when arranging, nylon wire 211 and steel wire 212 are spaced, and the spacing between steel wire 212 controls to be the spacing between 8-15 root nylon wire 211.
Because flexible pipe is when conveying material, flexible pipe mainly expands in radial directions, excessive expansion can directly cause breaking of flexible pipe, require that flexible pipe can restore upon inflation in time simultaneously, in the present embodiment, after adopting the framework layer of said structure, support owing to being provided with steel wire 212 in the radial direction at flexible pipe, steel wire 212 has good elasticity, flexible pipe can restore timely by it after hose expansion, the overexpansion of flexible pipe can be controlled again simultaneously, and between steel wire 212, retain the pliability that larger spacing can ensure flexible pipe, prevent the framework layer flexible pipe flexibility that causes really up to the mark from declining.
Through technique scheme produce hose of hose pump through overtesting, its performance parameter is as follows: A: tolerable temperature :-20-120 DEG C, the highest delivery temperature of intermittence 250 DEG C;
B: working pressure: 0.5-2.5Mpa bursting pressure: >=3.2Mpa;
C: strong acid-base environment: 0.5Mpa pressure lower working life >=700h;
D: organic solvent, strong oxidizer, severe corrosive chemical mediator environment:
0.5Mpa pressure lower working life >=700h;
E: normal operating conditions: 0.5Mpa pressure lower working life >=1000h;
F: flexible pipe inner layer material flow resistance is little: be the material that in all solids material, friction factor (0.04) is minimum, thus greatly extend the working life of flexible pipe;
G: flexible pipe internal layer does not adhere to, has surface tension minimum in all solids material, does not adhere to any material, is applicable to conveying high-adhesiveness liquid;
H: inner layer material shows physiological inertia, without any chemical toxicity;
I: rubber Shao A hardness range: 70-75.
Known by above-mentioned parameter, this hose of hose pump has great raising relative to traditional soft pipe on indices.
