Abstract
The utility model discloses a water-ring type vacuum pump. The water-ring type vacuum pump comprises a pump, a circular disc, a pump cover, an impeller and a pump shaft, wherein chromium metal coating layers are plated on the pump body, the pump cover, the impeller and the pump shaft; and a stainless steel protective layer is plated on the surface of the circular disc. The water-ring type vacuum pump also comprises a machine seal packing box, a bolt and a baffle plate, on which chromium metal coating layers are plated. The water-ring type vacuum pump has the advantages that the chromium metal layers and the stainless protective layer are respectively added on components of the water-ring type vacuum pump, so that the abrasion resistant performance of the components is greatly enhanced, and the service life of the water-ring type vacuum pump is prolonged.
Description
Technical field
The utility model relates to the vacuum equipment field, and relates more specifically to a kind of Nash hytor.
Background technique
Nash hytor is called for short water ring pump, has obtained extensive use in the many manufacturing processs in industries such as oil, chemical industry, chemical fibre, machinery, mine, power, metallurgy, light textile, papermaking, medicine and food.For example, vacuum filtration, vacuum evaporation, vacuum feeding, vacuum outgas, vacuum conditioning and vacuum concentration etc.Because the process of water ring pump pressurized gas is an isothermal, so also can extract inflammable and explosive gas out.In addition, water ring pump also can extract the moisture gas of dust-laden.Several kinds of corrosion resistant Nash hytors are arranged in the market; Its main corrosion protection mode is for adding ceramic lined or using nonmetal (plastics) manufacturing etc.; But there are many problems in actual use; Degree of vacuum and rate of air sucked in required such as the vacuum pump that adds ceramic lined are very low, but not the intensity of each several parts such as its pump housing of the vacuum pump of made, impeller is lower.
The model utility content
To the problem that above-mentioned existing technology exists, the utility model provides a kind of Nash hytor, and it has excellent corrosion resistance.
To achieve these goals; The technological scheme that the utility model adopts is: a kind of Nash hytor; It comprises the pump housing, disk, pump cover, impeller and pump shaft, is coated with the crome metal coating on the pump housing, pump cover, impeller and the pump shaft, and is coated with stainless protection layer on the disc surfaces.
As preferably, Nash hytor also comprises machine envelope stuffing box, nut and baffle plate, all is coated with the crome metal coating on machine envelope stuffing box, nut and the baffle plate.
Compared with prior art; The advantage of the utility model is: owing on the parts of Nash hytor, added metallic chromium layer and stainless protection layer respectively; So the wear-resisting property of these parts is strengthened greatly, thereby prolonged the working life of Nash hytor.
Description of drawings
Fig. 1 is the cross sectional view according to the Nash hytor of the utility model.
Embodiment
To combine accompanying drawing that the utility model is described further below.
Referring to Fig. 1, it shows the cross sectional view according to the Nash hytor of the utility model.This Nash hytor comprises the pump housing 5, disk 4, pump cover 3, impeller 6 and pump shaft 1.Be coated with the crome metal coating on the pump housing 5, pump cover 3, impeller 6 and the pump shaft 1, and be coated with stainless protection layer on disk 4 surfaces.Because crome metal has wear resistance preferably, its coefficient of sliding friction is 50% of steel and a cast iron, so can produce good wear-resisting effect.Simultaneously, chromium has good corrosion resistance, so but the erosion of guard block protect it from corrosion fluid.Stainless protection layer has higher hardness, can protect disk 4 to avoid mechanical deterioration.
Nash hytor also comprises machine envelope stuffing box 2, nut 8 and baffle plate 7, also is coated with the crome metal coating on machine envelope stuffing box 2, nut 8 and the baffle plate 7.
Through with adding corresponding coating on the working surface of Nash hytor, so just degree of vacuum height, the rate of air sucked in required than the water ring vaccum pump of ceramic lined is big, and bigger than the Nash hytor intensity of nonmetallic material.
To the above-mentioned explanation of the disclosed embodiments, make related domain professional and technical personnel can realize or use the utility model.Multiple modification to these embodiments will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation in spirit that does not break away from the utility model or the scope in other embodiments among this paper.Therefore, the utility model will can not be limited to these embodiments shown in this paper, but will accord with principle disclosed herein and features of novelty the wideest corresponding to scope.
Claims (2)
1. Nash hytor, it comprises the pump housing, disk, pump cover, impeller and pump shaft, it is characterized in that, is coated with the crome metal coating on the said pump housing, said pump cover, said impeller and the said pump shaft, and is coated with stainless protection layer on the said disc surfaces.
2. Nash hytor according to claim 1 is characterized in that, said Nash hytor also comprises machine envelope stuffing box, nut and baffle plate, all is coated with the crome metal coating on said machine envelope stuffing box, said nut and the said baffle plate.
