Abstract
The utility model provides an antiseptic pump which comprises a check valve and an overflowing component which is fixed under the check valve. The antiseptic pump is characterized in that the surface, which contacts with water-flow, of the overflowing component is equipped with a corrosion resistant wear-resisting protective layer with thickness of 0.03-0.3mm. As the protective layer is disposed on the surface, which contacts with the water-flow, of the pump overflowing component of the utility model and the protective layer has corrosion resistant and wear-resisting functions, the surface of a flow passage becomes smooth and is hard to scale, thereby guaranteeing waterpower of the pump. The antiseptic pump has the advantages of perfect performance, low price and long service life.
Description
Affiliated technical field
The utility model is a kind of corrosion protection pump that contains corrosivity and solid particle medium liquid that is used to extract, and belongs to the pump technology field.
Background technique
Performance of over current component of water pump is worked in water for a long time, because phenomenons such as burn into wearing and tearing and cavitation appear in operating mode complexity easily, and descends because of fouling in the runner makes hydraulic performance.If adopt materials such as stainless steel, nickel cast iron to make these parts, then can guarantee corrosion protection and wear-resistant requirement, but these material prices are very expensive, the manufacturability of casting is also very poor, and difficulty of processing is very big, the cost height.
The model utility content
The purpose of this utility model provides and a kind ofly can overcome above-mentioned defective, price is low, technical performance is good corrosion protection pump.Particular content is as follows:
Comprise check valve and the flow passage components that are fixed on the check valve below, it is characterized in that: on the surface of flow passage components contact current, the protective coating that one deck anticorrosive wear-resistant decreases is set, protection bed thickness 0.03～0.3mm.
Described corrosion protection pump, flow passage components are the blower inlet casing of Bearing Installation on pump shaft, and the protective coating that one deck anticorrosive wear-resistant decreases is set on the inside and outside surface of blower inlet casing.
Described corrosion protection pump, flow passage components perhaps are pump shaft for be fixed on the impeller on the pump shaft through taper sheath.
Described corrosion protection pump, flow passage components are for for blower inlet casing, pump shaft and be fixed on impeller on the pump shaft.
Described corrosion protection pump, protective coating are the tungsten nickel element.
The utility model compared with prior art, electroplate one deck protective coating by the flow passage components at corrosion protection pump, this protective coating has corrosion-resistant, anti abrasive function, and runner also becomes smooth and less scaling because of the surface, thereby the hydraulic performance that guarantees pump is good, price is low again, long service life.
Description of drawings
Fig. 1 is the structural representation that the utility model pump shaft is electroplate with protective coating embodiment;
Fig. 2 is the structural representation that is electroplate with the blower inlet casing embodiment of protective coating;
Fig. 3 is the structural representation that is electroplate with the impeller embodiment of protective coating.
Among the figure: 1, bearing 2, blower inlet casing 3, impeller 4, taper sheath 5, pump shaft 6, protective coating 7, check valve
Embodiment
In the embodiment shown in fig. 1: flow passage components are fixed on the below of check valve 7, comprise pump shaft 5, be installed in the blower inlet casing 2 on the pump shaft 5 and be fixed on impeller 3 on the pump shaft 5 through taper sheath 4 through bearing 1, electroplating one deck thickness on the surface of pump shaft 5 is the protective coating 6 of 0.2mm, and the composition of protective coating 6 is the tungsten nickel element.
In the embodiment shown in Fig. 2～3: one deck protective coating 6 is all electroplated on the inside and outside surface that contacts current at blower inlet casing 2 with impeller 3, and protective coating 6 is a tungsten nickel element layer, and thickness is 0.08mm.
