Abstract
A mechanical pump with air leak protecting function comprises components, such as a pump shell, an impeller, an impeller chamber, a shaft, a bearing, a power connector and the like, wherein a sealing chamber is sleeved on the shaft between the impeller chamber and the bearing, and sealing liquid is injected into the sealing chamber. The sealing liquid is injected into the sealing chamber of the design, since materials are circulated by a mechanical pump under a vacuum state, the mechanical pump and a separate tower have an altitude of sixteen meters, thereby forming a certain atmosphere pressure difference, the sealing liquid of the sealing chamber can not enter vacuum circulating system, thereby playing the function of insulating air, and improving the service life of filling of the separate tower.
Description
Technical field
The utility model relates to a kind of pump-unit, a kind of mechanical pump with wheel leakage protective function of concrete finger.
Background technique
Fatty acid in process of production, the general high tower separating technology that adopts, mechanical pump belongs to the ring in the fatty acid high tower piece-rate system, be exactly under high vacuum state, material to be circulated by mechanical pump, through heater heats and vaporizing, utilize the packing tower material that steam point is different to separate again and draw product oleic acid, stearic acid.Mechanical pump is to be connected and the impeller rotation with axle by power plant, play the effect of extracting material, for preventing that air is brought in the separator, generally between axle and the impeller storehouse adopt filler or mechanical seal, but axle is in the process that turns round, and certain clearance is arranged between the Sealing, because material has certain corrosivity, under high vacuum, the condition of high temperature, mechanical pump still can leak gas, and gas can make filler in the packing tower because of oxidation reduction of service life.
The model utility content
The purpose of this utility model overcomes deficiency of the prior art exactly, and a kind of mechanical pump with wheel leakage protective function is provided.
For achieving the above object, the technological scheme that the utility model adopted is achieved in that
A kind of mechanical pump with wheel leakage protective function is provided, comprises that parts such as pump case, impeller, impeller storehouse, axle, bearing and power link constitute, be with a gas-tight silo on the described axle between impeller storehouse and bearing, inject sealing fluid in the gas-tight silo.
Advantage of the present utility model is: injected sealing fluid in the designed gas-tight silo, because material is to be circulated by mechanical pump under the state of high vacuum, mechanical pump and separator have 16 meters elevation, formed certain atm difference, the sealing fluid of gas-tight silo does not enter the vacuum cycle system, thereby played the effect that cuts off air, the working life of having improved the separator filler.
Description of drawings
Accompanying drawing is a kind of internal structure schematic representation of the utility model.
Embodiment
See also accompanying drawing, it shown in the figure internal structure of a mechanical pump, constitute by 5 parts such as impeller 1, impeller storehouse 2, axle 3, bearing 4 and power links, on one section axle 3 between impeller storehouse 2 and the bearing 4, be with a gas-tight silo 6, injected sealing fluid in the gas-tight silo 6.
Claims (1)
1. mechanical pump with wheel leakage protective function; comprise that pump case, impeller (1), impeller storehouse (2), axle (3), bearing (4) and power link (5) parts constitute; it is characterized in that: be with a gas-tight silo (6) on the described axle (3) between impeller storehouse (2) and bearing (4), inject sealing fluid in the gas-tight silo (6).
