Abstract
The invention discloses a high-temperature melting salt pump with a novel lubricating structure. The high-temperature melting salt pump comprises a motor cabinet (1), a pump shaft (2) and a bearing box (3); the bearing box (3) is internally provided with a bearing (4); a bearing shaft sleeve (5) is arranged between the bearing (4) and the pump shaft (2); an oil isolation sleeve (6) is arranged between the bearing shaft sleeve (5) and the pump shaft (2); the contacting position of the end surfaces of the oil isolation sleeve (6) and the motor cabinet (1) is provided with a sealing pad (7a); the contacting position of the bearing box (3) and the motor cabinet (1) is provided with a sealing pad (8b); and the bearing box (3) is externally connected with an oil leveler (9). By adopting the structure, the pump shaft and the lubricant can be separated so as to reduce leakage, therefore, the overhauling and maintenance period of a pump is prolonged, the maintenance expense is saved, the production cost is reduced, and the hidden safety problem is reduced simultaneously.
Description
Technical field
The present invention relates to a kind of pump, especially relate to a kind of high-temperature melting salt pump with novel lubricating structure.
Background technique
High-temperature melting salt pump is the vertical submerged pump structure, is mainly used in industrial departments such as producing aluminium oxide, melamine, ion film caustic soda, and fed sheet of a media is a high-temperature molten salt, and fused salt is NaNo
37%, NaNO
240% and KNO
353% mixes, and temperature is about 450 ℃.Bearing is the vitals of pump, and pump is in long-time running, and bearing can wear and tear, so the lubricated meeting of bearing has influence on the normal operation of pump.For high-temperature melting salt pump, the lubricated employing thin oil lubricant of bearing is in the operation process of pump; the leakage of lubricant oil usually can take place; cause fault frequent, not only loss lubricant grease, increased recondition expense simultaneously, and brought very big potential safety hazard for whole service stability.
Summary of the invention
The purpose of this invention is to provide a kind of high-temperature melting salt pump with novel lubricating structure that can prevent oil leak.
The problem that will solve required for the present invention realizes by the following technical solutions: it comprises motor cabinet, pump shaft and bearing housing, be provided with bearing in the bearing housing, be provided with the bearing axle sleeve between bearing and the pump shaft, it is characterized in that between described bearing axle sleeve and the pump shaft oil removal cover being set, at oil removal cover and motor cabinet end face contacting point sealing gasket is set, at bearing housing and motor cabinet contacting point sealing gasket is set, external oil ga(u)ge on the bearing housing.
The said structure that the present invention adopts is provided with the oil removal cover between bearing axle sleeve and the pump shaft, pump shaft and lubricant oil can be kept apart to reduce leakage, thereby maintenance, the maintenance period of pump have been prolonged, save maintenance expenses, reduced cost of production, also reduced potential safety hazard simultaneously.
Description of drawings
The present invention is described further below in conjunction with accompanying drawing:
Accompanying drawing is depicted as structural representation of the present invention
Wherein 1, motor cabinet 2, pump shaft 3, bearing housing 4, bearing 5, bearing axle sleeve 6, oil removal cover 7, sealing gasket a 8, sealing gasket b 9, oil ga(u)ge
Embodiment
By accompanying drawing as can be known, this high-temperature melting salt pump with novel lubricating structure comprises motor cabinet 1, pump shaft 2 and bearing housing 3, be provided with bearing 4 in the bearing housing 3, be provided with bearing axle sleeve 5 between bearing 4 and the pump shaft 2, oil removal cover 6 is set between described bearing axle sleeve 5 and the pump shaft 2, with motor cabinet 1 end face contacting point sealing gasket 7a is set at oil removal cover 6, sealing gasket 8b is set, external oil ga(u)ge 9 on the bearing housing 3 in bearing housing 3 and motor cabinet 1 contacting point.The oil removal cover can adopt No. 45 steel to make.The lubricated employing thin oil lubricant of bearing of the present invention, the liquid level of thin oil is lower than the top of oil removal cover, so just pump shaft and lubricant oil can be kept apart, at oil removal cover and motor cabinet end face contacting point sealing gasket is set, at bearing housing and motor cabinet contacting point sealing gasket is set also equally, oil leak can be further prevented, the liquid level position of lubricant oil can also be observed by external oil ga(u)ge.
Claims (1)
