Abstract
The utility model relates to a boosting pump, in particular to a backflow boosting pump for producing triethylamine resin. The backflow boosting pump consists of a shell, a pump shaft, an impeller, a motor, a shell front cover and a shell rear cover, wherein one side of the shell is provided with the shell front cover, and the other side of the shell is provided with the shell rear cover; the pump shaft is arranged in the shell rear cover; one end of the pump shaft is connected with the motor, and the other end of the pump shaft is extended into an impeller chamber; the impeller is arranged at the end of the pump shaft in the impeller chamber; a central hole is formed in the impeller chamber; and a water inlet and a water outlet are formed in the shell at the upper end and the lower end of the impeller chamber respectively. The backflow boosting pump has a small volume, a simple structure and a simple, convenient and smooth working process; and by the boosting pump, the phenomenon that blades of the conventional boosting pump are easy to clamp can be effectively prevented, and water inlet resistance and pressure losses are reduced. The shell rear cover is arranged on the shell through a connecting plate, so that the backflow boosting pump is easy and convenient to assemble and maintain, and the problem of inconvenience for assembly and maintenance in the prior art is solved.
Description
Technical field
The utility model relates to a kind of suction booster, is specifically related to a kind of backflow suction booster that is used for the triethylamine production of resins.
Background technique
The triethylamine resin in process of production; Material in the reaction kettle begins when reaching certain temperature to reflux; But owing to have certain pressure in the reaction kettle; The material that refluxes is to lean on potential difference pressure natural back flow in reaction kettle, so capacity of reflux is difficult to guarantee, and then makes quality of product receive very big influence.Existing solution mainly is on the reflow pipe of manufacturing mechanism, to install a suction booster additional, so that the capacity of reflux of material is guaranteed, and then guarantees that quality of product is not affected.Its pump body structure length of present suction booster is excessive, complex structure, behind the work certain hour since wearing and tearing very easily cause sealing surface to damage even scrap, and very inconvenience of installation and maintenance.
Summary of the invention
The purpose of the utility model is: provide a kind of simple in structure, the convenient and anti abrasive backflow suction booster that is used for the triethylamine production of resins of installation and maintenance.
The utility model is to realize above-mentioned purpose through following technological scheme:
A kind of backflow suction booster that is used for the triethylamine production of resins; It is made up of housing, pump shaft, impeller, motor, housing protecgulum, housing bonnet; It is characterized in that: a side of housing is provided with the housing protecgulum; Be provided with the fluid passage in the housing protecgulum, the opposite side of housing is equipped with the housing bonnet through connecting plate; Through Bearing Installation pump shaft is arranged in the housing bonnet, an end of pump shaft extends to the bonnet outer end and is connected with motor through coupling; The other end of pump shaft extends to the blade wheel chamber in the housing; Pump shaft termination in the blade wheel chamber is equipped with impeller; Blade wheel chamber is provided with center hole, is respectively arranged with water intake and water outlet on the housing of blade wheel chamber's upper/lower terminal, is provided with the fluid passage in the protecgulum; Described water outlet is communicated with blade wheel chamber, and water intake is communicated with blade wheel chamber through fluid passage and center hole.
Be respectively arranged with seal ring between described housing protecgulum and connecting plate and the housing.
Pump shaft between described connecting plate and the housing bonnet is provided with outside framework oil seal 12, and the pump shaft in the blade wheel chamber is provided with mechanical seal.
The beneficial effect of the utility model is:
This backflow suction booster volume is little, simple in structure; Material gets into blade wheel chamber by water intake through fluid passage and center hole; Under the rotation of impeller, flow out through water outlet, make that the water inlet resistance and the pressure loss are little, the housing bonnet is installed on the housing through connecting plate; Avoid the very problem of inconvenience of existing installation and maintenance, therefore made installation and maintenance be convenient to easy carrying out.
Description of drawings:
Accompanying drawing is the structural representation of the utility model.
Among the figure: 1, housing, 2, pump shaft, 3, impeller, 4, motor, 5, the housing protecgulum; 6, housing bonnet, 7, the fluid passage, 8, connecting plate, 9, bearing; 10, blade wheel chamber, 11, coupling, 12, outside framework oil seal, 13, seal ring; 14, center hole, 15, water intake, 16, water outlet, 17, mechanical seal.
Embodiment:
This backflow suction booster that is used for the triethylamine production of resins is made up of housing 1, pump shaft 2, impeller 3, motor 4, housing protecgulum 5, housing bonnet 6; One side of housing 1 is provided with housing protecgulum 5; Be provided with fluid passage 7 in the housing protecgulum 5, the opposite side of housing 1 is equipped with housing bonnet 6 through connecting plate 8.Connecting plate 8 constitutes blade wheel chamber 10 with the cavity of housing 1.Be respectively arranged with seal ring 13 between housing protecgulum 5 and connecting plate 8 and the housing 1.Through bearing 9 pump shaft 2 is installed in the housing bonnet 6, an end of pump shaft 2 extends to the bonnet outer end and is connected with motor 4 through coupling 11.
The other end of pump shaft passes connecting plate 8 and extends in the blade wheel chamber 10; Pump shaft 2 terminations in the blade wheel chamber 10 are equipped with impeller 3; Blade wheel chamber 10 is provided with center hole 14; Be respectively arranged with water intake 15 and water outlet 16 on the housing 1 of blade wheel chamber's 10 upper/lower terminals, water outlet 16 is communicated with blade wheel chamber 10, and water intake 15 is communicated with blade wheel chamber 10 through fluid passage 7 and center hole 14.Pump shaft 2 between connecting plate 8 and the housing bonnet 6 is provided with outside framework oil seal 12, and the pump shaft 2 in the blade wheel chamber 10 is provided with mechanical seal 17.
During this backflow suction booster work, pump shaft 2 rotates under the drive of motor 4, and impeller 3 is rotated thus; Material gets into blade wheel chamber 10 by water intake 15 through fluid passage 7 and center hole 14; Under the rotation of impeller 3, flow out through water outlet 16; The easy smoothness of working procedure can prevent effectively that existing suction booster blade is prone to stuck phenomenon, makes the water inlet resistance and the pressure loss reduce simultaneously.Housing bonnet 6 is installed on the housing 1 through connecting plate 8, therefore makes installation and maintenance be convenient to easy carrying out, and has avoided the very problem of inconvenience of existing installation and maintenance.
