Abstract
The utility model relates to a corrosion resistant submerged pump which is mainly used as a pump for industrial use and belongs to the technical field of water pumps. The utility model is characterized in that the utility model is provided with a liquid inlet pipe in which a one-way valve is arranged; the liquid inlet pipe and a pump shaft are on the same shaft central line; the bottom of the liquid inlet pipe is provided with a filter; a lower bearing of the pump is provided with a bearing sealing box; a back flow hole is arranged on a middle supporting frame of the pump. The corrosion resistant submerged pump can satisfy the requirements of different occasions for submerged depth, and the range of application is wide. The pump shaft is short and is not easy to twist and deform, and the service life of the utility model is extended.
Description
The utility model relates to the structure of Under Water Pumps, belongs to the pump technology field.
Kind, the specification of Under Water Pumps are a lot, have vertical, have horizontal.For example 90226767.1 overall plastic Under Water Pumps is exactly a kind of vertical industrial pump, mainly is made of motor, support, bearing bracket stand, middle adapter, drain pipe, pump case, pump shaft, bonnet, impeller etc.This pump has corrosion resistant performance preferably, but owing to be directly to establish liquid entering hole on pump case, can not satisfy the requirement of some use occasion insertion depths.Moreover this pump is owing to be provided with long pump shaft, and easy torsional deformation in the using process influences working life of pump.
The purpose of this utility model is exactly to overcome the deficiency that existing Under Water Pumps exists, and the corrosion resistant Under Water Pumps of a kind of insertion depth wide ranges, long service life is provided.
The purpose of this utility model is to realize by the improvement to existing Under Water Pumps: the corrosion resistant Under Water Pumps comprises motor 1, electric machine support 2, coupling 3, bearing bracket stand 4, base plate 6, intermediate support 7, bonnet 8, anti-wear sleeve 9, impeller 10, pump case 11, filter 15, drain pipe 16, pump shaft 17, it is characterized in that Under Water Pumps is provided with liquid inlet pipe 12 and comprises the one-way valve that adapter 13, ball sealer 14 constitute, liquid inlet pipe 12 and pump shaft 17 are on same shaft axis, one-way valve is located in the liquid inlet pipe, filter 15 is located at the bottom of liquid inlet pipe 12, establishes return port 18 on the intermediate support 7.In order to prevent the up corrosion bearing of gas, lower bearing is provided with bearing seal case 5.During Under Water Pumps work, the rotation of impeller throws away liquid to tangent direction, produces Negative Pressure Difference in pump chamber and the liquid inlet pipe 12, and one-way valve is opened, and liquid enters pump chamber through filter 15, liquid inlet pipe 12.During shutdown, ball sealer 14 falls automatically, closes one-way valve, makes the full liquid of storage in the pump chamber, and need not drainage when starting shooting next time, can directly start shooting.
The utility model is rational in infrastructure simple, manufacture easily, cost is low, owing to set up liquid inlet pipe, the depth bounds that pump inserts liquid is big, can satisfy the requirement of different occasions, therefore and shortened the length of middle adapter and pump shaft, save raw material, avoided the torsional deformation of pump shaft, prolonged the working life of pump.
Accompanying drawing is a structural representation of the present utility model, 1 motor, 2 electric machine supports, 3 coupling, 4 bearing bracket stands, 5 bearings, sealed case, 6 base plates, 7 intermediate supports, 8 bonnets, 9 anti-wear sleeves, 10 impellers, 11 pump cases, 12 liquid inlet pipes, 13 adapters, 14 ball sealers, 15 filters, 16 drain pipes, 17 pump shafts, 18 return ports among the figure.
Narrate case study on implementation of the present utility model below in conjunction with accompanying drawing.
Motor 1 is installed on the base plate 6 by electric machine support 2, bearing bracket stand 4 etc., and lower bearing is established bearing seal case 5, prevents the up corrosion bearing of corrosive gas.On intermediate support 7, establish return port 18, make outside the timely efflux pump of the up liquid of part.The liquid entering hole of Under Water Pumps is established liquid inlet pipe 12, establishes the one-way valve that is made of adapter 13, ball sealer 14 in liquid inlet pipe, and liquid inlet pipe 12 and pump shaft 17 are on same shaft axis, and filter 15 is established in the bottom of liquid inlet pipe 12.
