Abstract
The utility model discloses a compound environmental protection diaphragm of diaphragm pump, including the rubber layer, be equipped with the fabric enhancement layer in the middle of the rubber layer, the rubber layer outside is equipped with anti -corrosion coating, anti -corrosion coating is the polytetrafluoroethylene material. The utility model discloses simple structure, reasonable in design through add the fabric enhancement layer in the middle of the rubber layer, has increased the intensity of diaphragm, has improved life, and the endurance number of times can rise to 800~1, 200 ten thousand times. Through at rubber layer surface interpolation anti -corrosion coating, unfamiliar resistance to corrosion has been improved.
Description
Technical field
The utility model relates to pump technical field, specifically a kind of diaphragm pump composite environmental-friendly diaphragm.
Background technique
Pump is conveying liquid or the one machinery making fluid pressurization, and it sends the mechanical energy of prime mover or other external energies to liquid, and liquid energy is increased instantaneously.Pump is mainly used to conveying liquid and comprises water, oil, acid and alkali corrosion liquid, emulsified liquid, suspended emulsion and liquid metal etc., also can carry liquid, gaseous mixture and the liquid containing suspended solids.The working principle of pump relies on operation element (diaphragm of rubber) to do in pumping cylinder back and forth or rotation motion, makes swept volume alternately increase and reduce, to realize suction and the discharge of liquid.The reciprocating positive displacement pump of operation element (diaphragm of rubber) is called reciprocating pump, sucks and discharge process hockets in same pumping cylinder, and is controlled by suction valve and expulsion valve, forces liquid to transfer to discharge side from suction side.The barrier film majority used in current pump adopts gum (as: nitrile butadiene rubber, neoprene, fluorine rubber etc.) to make, in performance, durable, corrosion protection and life-span etc., be all difficult to reach requirement, cause the replacement frequency of pump to increase, badly influence terminal client and use.
Summary of the invention
The purpose of this utility model is to provide a kind of diaphragm pump composite environmental-friendly diaphragm, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
A kind of diaphragm pump composite environmental-friendly diaphragm, comprises rubber layer; Be provided with fabric reinforcement layer in the middle of described rubber layer, rubber layer both sides are provided with corrosion-resistant coating.
As further program of the utility model: described corrosion-resistant coating is teflon material.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, by adding fabric reinforcement layer in the middle of rubber layer, add the intensity of diaphragm, improve working life, endurance number of times can rise to 800 ~ 1,200 ten thousand times.By adding corrosion-resistant coating on rubber layer surface, improve anticorrosive property.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-corrosion-resistant coating, 2-fabric reinforcement layer, 3-rubber layer.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1, a kind of diaphragm pump composite environmental-friendly diaphragm, comprises rubber layer 3; Be provided with fabric reinforcement layer 2 in the middle of described rubber layer 3, rubber layer 3 both sides are provided with corrosion-resistant coating 1.Both added the intensity of diaphragm, and had again good anticorrosion ability, add working life.
Further, corrosion-resistant coating 1 described in the utility model is teflon material, and antiacid alkali resistant, is insoluble to various organic solvent, has good anticorrosive property.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any reference character in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should by specification integrally, and the technological scheme in each embodiment also through appropriately combined, can form other mode of executions that it will be appreciated by those skilled in the art that.
Claims (2)
