Technical field
The utility model is related to pump equipment field, specifically a kind of floating type impeller port ring device.
Background technology
With the accelerated development of current urbanization both at home and abroad, the raising of industrial automatization and the increasing of national economy
It is long, it is very big to the annual requirement of the floating type impeller port ring device of DL series in the market.The pump of the series is applied in following multiple necks
Domain：
1st, urban water supply：Water factory filters send water, supervisor's supercharging, skyscraper to be pressurized with conveying, water factory's subregion.
2nd, industry supercharging：Flow water system, cleaning system, high-pressure washing system, fire-fighting system.
3rd, industrial liquid conveys：Cooling and air-conditioning system, boiler feedwater and condenser system, lathe are mating, acid and alkaline
Medium conveys.
4th, water process：Ultrafiltration system, counter-infiltration system, Distallation systm, separator and swimming pool water treatment system.
5th, it irrigates：Field irrigation, sprinkling irrigation, trickle irrigation.
But existing vertical multi-stage centrifugal pump has the following problems：Common impeller intake ring, all using close-fitting
Mode is fixed on the entrance of volute, because to play the role of preventing the gap very little of liquid reflux, choma and impeller, it is desirable that
There is a good assembly precision, but in multistage pump, have more impellers and volute, it is impossible to which the gap of every impeller and volute is all very
Uniformly, the gap of impeller and volute certainly will be increased, just can guarantee that impeller does not wipe leaf with volute, gap increases the non-return to liquid
With regard to unobvious, the efficiency of water pump is just substantially reduced for effect.The long axis of water pump has bounce in high speed rotation, when leading to pump working
Noise is greatly and vibration is apparent.
Invention content
The purpose of this utility model is to provide a kind of floating type impeller port ring device.
The utility model will solve existing impeller intake ring structure and be related to unreasonable, lead to the working efficiency of water pump
It is low, noise and vibration problems during work.
The technical solution of the utility model is:A kind of floating type impeller port ring device, the device are centrifuged set on vertical multi-stage
At the multi-stag impeller of pump, which includes floating choma and choma support device, and the choma support device includes lower solid
Determine part, support platform and connector, lower to be connected between fixing piece and support platform by connector, described choma support device
Set on the outside of impeller, the lower fixing piece is fixed on by way of spot welding on volute, and the support platform is close to described
Impeller, the floating choma are placed on the outside of the impeller, and relocatable are placed in the support platform.
Preferably, the gap between the floating choma and the impeller is 0.2-0.3mm.
As it is further preferred that the floating choma uses too fluorine dragon wear-resistant material.
Preferably, multistage volute is equipped in the multi-stag impeller, is equipped with impeller in each volute, the impeller with
Axle sleeve is equipped between the shaft of vertical multi-stage centrifugal pump, the impeller set on bottom is first order impeller, the first order leaf
The back side of wheel is equipped with sliding bearing.
As still more preferably, the material for sliding bearing is silicon carbide, and the axle sleeve uses hard stainless steel.
The beneficial effects of the utility model are：The structure design of the utility model is reasonable, is in particular in：1st, by impeller port ring
It is designed to floating type, the material of choma is using the too fluorine dragon of light wear-resistant, and the assembling of choma is not by the shadow of volute assembly precision
It rings, substantially increases the performance and working efficiency of water pump；2nd, a sliding bearing is designed at first order impeller, prevents long axis in height
It generates and perturbs when speed rotation, pre- waterproof pump wipes leaf, vibrates, the generation of noise, improves the working life of pump.
Description of the drawings
Fig. 1 is the structure diagram of improved vertical multi-stage centrifugal pump.
Fig. 2 is the enlarged structure schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and embodiments.
As shown in the figure, the utility model is set at the multi-stag impeller 1 of vertical multi-stage centrifugal pump, which includes floating mouth
Ring 4 and choma support device 8, the choma support device 8 include lower fixing piece 8-1, support platform 8-3 and connector 8-2,
It is connected between lower fixing piece 8-1 and support platform 8-3 by connector 8-2, the choma support device 8 is set on impeller 3
Outside, the lower fixing piece 8-1 are fixed on by way of spot welding on volute 2, and the support platform 8-3 is close to the impeller
3, the floating choma 4 is placed on the outside of the impeller 3, and relocatable is placed on the support platform 8-3.
Preferably, the gap between the floating choma 4 and the impeller 3 is 0.2-0.3mm.
As it is further preferred that the floating choma 4 uses too fluorine dragon wear-resistant material.
Floating choma 4 is designed to floating type, the material of floating choma 4 is using the too fluorine dragon of light wear-resistant, floating mouth
The assembling of ring 4 is not influenced by 2 assembly precision of volute, and the gap of impeller 3 and floating choma 4 can also be made very small, and gap is only
