Abstract
The utility mode relates to a novel chemical centrifugal pump comprising a pump body, an impeller, a pump cover, a sealing end cover and a pump shaft, wherein the impeller is formed in a sealing cavity formed by the pump body, the sealing end cover and the pump cover, and the impeller is arranged at the left end of the pump shaft which penetrates through the sealing end cover by virtue of an impeller nut; the pump shaft is provided with a shaft sleeve, a sealing component is arranged at the joint of the pump cover and the shaft sleeve, and an oil seal is arranged at the joint of the sealing end cover and the shaft sleeve; one bearing is respectively arranged at the two ends of the pump shaft in a suspension, a grease fitting is arranged above each bearing, and the bearings are fixed by virtue of bearing glands. The novel chemical centrifugal pump disclosed by the utility model is good in sealing effect and is efficient and energy-saving.
Description
Technical field:
The utility model relates to a kind of pump, especially relates to a kind of good sealing effect, energy-efficient Novel chemical pump.
Technical background:
Along with the progress of science and technology, the range of needs of pump is more and more wider, and current I H type chemical centrifugal pump can only be carried the medium of physical property similar water, can not carry the medium that contains more impurity and particle, otherwise will cause obstruction, and the phenomenon phenomenon such as leakage occurs easily.
Summary of the invention:
The purpose of this utility model provides a kind of good sealing effect, energy-efficient Novel chemical centrifugal pump.
The utility model is achieved in that a kind of Novel chemical centrifugal pump comprises the pump housing, impeller, pump cover, end cover, pump shaft, be provided with impeller in the Seal cage that the pump housing, end cover and pump cover form, impeller is installed in the pump shaft left end that passes end cover by impeller nut, it is characterized in that: be provided with axle sleeve on the pump shaft, pump cover and axle sleeve joint are provided with sealed member, and end cover and axle sleeve joint are provided with oil sealing; Two ends respectively arrange a bearing on the pump shaft in the suspension, and the bearing top is provided with grease nipple, and described bearing is fixed by bearing gland; Described impeller is unshrouded impeller.
The utility model good sealing effect, energy-efficient.
Description of drawings:
Fig. 1 is the utility model structural representation.
Among the figure 1, the pump housing, 2, impeller nut, 3, impeller, 4, pump cover, 5, sealed member, 6, end cover, 7, oil sealing, 8, bearing, 9, suspension, 10, grease nipple, 11, axle sleeve, 12, cooling water nozzle, 13, bearing gland, 14, pump shaft.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
A kind of Novel chemical centrifugal pump, comprise the pump housing 1, impeller 3, pump cover 4, end cover 6, pump shaft 14, be provided with impeller 3 in the Seal cage that the pump housing 1, end cover 6 and pump cover 4 form, impeller 3 is installed in pump shaft 14 left ends that pass end cover 6 by impeller nut 2, it is characterized in that: be provided with axle sleeve 11 on the pump shaft 14, pump cover 4 is provided with sealed member 5 with axle sleeve 11 joints, and end cover 6 is provided with oil sealing 7 with axle sleeve 11 joints; Two ends respectively arrange a bearing 8 on the pump shaft 14 in the suspension 9, and bearing 8 tops are provided with grease nipple 10, and described bearing 8 is fixing by bearing gland 13; Described impeller 3 is unshrouded impeller.During implementation, the utility model is to improve on the basis of IH type chemical pump to form, good seal performance, changed the drawback of the medium that the IH pump can only conveying material character similar water, the utility model can carry solid content up to 35% material, 8000 hours nothings of continuous operation are leaked under normal circumstances, again because adopt the open architecture impeller, so can not stop up because solid content is too high.
