The utility model discloses utilize the polytetrafluoroethylene anticorrosive coating to play the preservation, can realize that the drinking water of carrying is clean pollution -free, satisfy sanitary authentication requirement completely, make simple process moreover, reduced manufacturing cost, improve production efficiency.
Description
Technical field
The utility model relates to pump housing field, particularly a kind of novel anticorrosion iron pump housing being applied to low profile thermal water-circulating pump.
Background technique
Low profile thermal water-circulating pump is used for Living Water field, does not allow to cause water pollution, need in strict conformity with the requirement of potable water certification.As the pump housing of one of the main flow passage components of water pump, its material is generally ironcasting, and for preventing corrosion, current pump housing inner flow passage generally adopts electrophoresis or enamel technology process.But adopt electrophoresis process treatment surface, antiseptic effect is undesirable, especially can not meet drinking water sanitary standard; And the operational condition of enamel technology is very harsh, the pump housing is heated to more than 800 DEG C by enamel process need, thus causes part gross distortion, and dimensional changes is large, and product is difficult to assembling, and reduces water pump performance and operational efficiency.In addition, existing pump body structure needs to install a stainless steel choma in addition additional, and form seal clearance in order to coordinate with impeller port ring, thus pump housing manufacturing process is complicated, and cost is high.
Model utility content
The purpose of this utility model is above-mentioned deficiency for prior art and defect, provides a kind of novel anticorrosion iron pump housing, and the antiseptic property of this novel anticorrosion iron pump housing is remarkable, and preparation process is simple, improves water pump performance.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of novel anticorrosion iron pump housing, comprise cast iron pump body, described cast iron pump body inside has pump chamber and the tunnel inlets section be communicated with described pump chamber respectively and runner exit section, it is characterized in that, the inwall of described pump chamber and the inwall of described tunnel inlets section and runner exit section are provided with anticorrosive PTFE layer.
In a preferred embodiment of the present utility model, described pump chamber is provided with the joint of described tunnel inlets section the annular stopper coordinated with the front end of impeller, the surface of described annular stopper is provided with described anticorrosive PTFE layer.
In a preferred embodiment of the present utility model, the outer end of described tunnel inlets section and runner exit section is respectively arranged with first, second flange, and the exterior edge face of first, second flange described is also provided with described anticorrosive PTFE layer.
In a preferred embodiment of the present utility model, described anticorrosive PTFE layer comprises polytetrafluoroethylene spray bottom and sintering polytetrafluoroethylene surface layer.
Owing to have employed technological scheme as above, the utility model utilizes anticorrosive PTFE layer to play antisepsis, can realize the potable water cleanliness without any pollution carried, meet health authentication requesting completely, and preparation process is simple, reduces cost of production, enhances productivity.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Fig. 2 is the structural representation after a kind of embodiment of the utility model coordinates with impeller.
Fig. 3 is the I place enlarged view of Fig. 2.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, setting forth the utility model further below.
See a kind of novel anticorrosion iron pump housing shown in Fig. 1 to Fig. 3, comprise cast iron pump body 100, cast iron pump body 100 inside has pump chamber 110 and the tunnel inlets section 120 be communicated with pump chamber 110 respectively and runner exit section 130.The inwall of pump chamber 110 and the inwall of tunnel inlets section 120 and runner exit section 130 are provided with anticorrosive PTFE layer 1.Teflon is also known as Teflon, and anticorrosive PTFE layer 1 has the not good characteristic such as viscosity, heat resistance, sliding, wearability, corrosion resistance, the moisture-resistant feature of environmental protection, can realize the potable water cleanliness without any pollution carried, meet health authentication requesting completely.
Anticorrosive PTFE layer 1 in the present embodiment comprises polytetrafluoroethylene spray bottom and sintering polytetrafluoroethylene surface layer, it is realized by series of process route, and its process route is: empty burning (oil removing)--shot-peening--primary coat--drying--cooling-face painting-sinter molding.Particularly: the pump housing semi-finished product processed heat through high temperature degreasing by (1), surface and oil contaminant is decomposed remove, (2) again runner is carried out to shot-peening, blows off process, make water passage surface more bright and clean smooth, to strengthen the adhesion of teflon coatings, (3) first time spraying Teflon bottom, form polytetrafluoroethylene spray bottom, cooling after middle low temperature drying insulation, (4) second time spraying Teflon surface layer, through 380 DEG C of sintering, forms sintering polytetrafluoroethylene surface layer, after insulation, air cooling is shaped, and obtains cast iron pump body 100.
Pump chamber 110 and the joint of tunnel inlets section 120 are provided with the annular stopper 140 coordinated with the front end 210 of impeller 200, the surface of annular stopper 140 are provided with anticorrosive PTFE layer 1.The front end 210 of impeller 200 and annular stopper 140 directly coordinate formation seal clearance mutually, and centre does not need to install stainless steel transition choma additional, can realize the simplification of pump housing preparation process thus.In addition, the size of the front end 210 of impeller 200 and the size of annular stopper 140 are all realized by machining (as turnery processing), the required precision of size can be ensured completely, so can realize≤seal clearance of 0.3mm, thus reduce the leakage rate at water pump operationally choma place, improve water pump performance, improve volumetric efficiency.
The outer end of tunnel inlets section 120 and runner exit section 130 is respectively arranged with first, second flange 121,131, the exterior edge face of first, second flange 121,131 is also provided with anticorrosive PTFE layer 1, prevent itself and miscellaneous part joint from being corroded, ensure drinking water cleaning degree further.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
