Abstract
The utility model relates to a new-style high speed and multilevel centrifugal water pump. The utility model is based on mass market research, and ascertains the flow rate of the pump between 10 to 40L/S according to the user requirement and the technical feasibility; the pump lift is ascertained more than 60m. The utility model is characterized in that adopting different combinations of the impellers and the entrance buckets of 30m single-stage pump lift and 40m single-stage pump lift which have the same flow rate, the same matched main spindle and middle piece, making use of the impeller differences of the pumps with 30m single-stage pump lift and 40m single-stage pump lift, the high speed and multilevel centrifugal water pump can realize the effluent pressure bracket according to 10m every stage pump lift when the pump lift of the pump is more than 60m. The utility model has the advantages that the volume is small, the weight is light, the efficiency is high, the cost is low, the universality of product components is high, and the pattern selection of the plant supervision and the usage of the pump are convenient.
Description
The invention belongs to the water pump class, is a kind of high-speed, multi-stage centrifugal water pump that can carry out the discharge pressure stepping by 10 meters of every grade of lifts.
Increasing along with tall building, multi-stage centrifugal pump use in daily life is more and more general.According to the requirement of fire codes, fire water pump should be able to carry out the pressure stepping for 10 meters by every grade of lift, satisfies the requirement of user's different pressures grade as far as possible.This point hour can reach at pump capacity; But it is when pump capacity is big, technical owing to be subjected to the restriction of water pump single-stage impeller lift but to be difficult to simply reach.Existing product generally adopts lowspeed pump (synchronous speed 1500r/min), 20 meters of single-stage lift, and interstage pressure is by cutting water pump vane or departing from the rated point type selecting and satisfy customer requirements.Like this, not only limited water pump and adopted high speed pump (synchronous speed 3000r/min), improved the water pump cost of goods manufactured, increased the water pump production management and used the type selecting difficulty, and, also reduced pump efficiency, increased the daily cost of use of user.
The present invention wishes that can provide a kind of to people carries out discharge pressure stepping, high efficiency, low cost, product component highly versatile, water pump production management and use type selecting high-speed, multi-stage centrifugal water pump easily by 10 meters of every grade of lifts.
The present invention is based upon on the basis of mass market investigation, according to customer requirements and technical feasibility, pump capacity is determined between 10L/S～40L/S; Lift is determined more than 60 meters.The object of the present invention is achieved like this: adopt the 30 meters impellers identical with the stage casing with 40 meters identical, supporting main shafts of two kinds of flows of single-stage lift of single-stage lift and the various combination of stator, utilize poor between 40 meters two kinds of water pump vanes of 30 meters of single-stage lift and single-stage lift, more than 60 meters, realize that the high-speed, multi-stage centrifugal water pump carries out the discharge pressure stepping for 10 meters by every grade of lift in pump head.Pump head concrete stepping below 160 meters is seen following example table (pump head is analogized by table more than 160 meters):
In particular: this kind high-speed, multi-stage centrifugal pump comprise 30 meters impellers of single-stage lift, 40 meters impellers of single-stage lift, 30 meters stators of single-stage lift, 40 meters stators of single-stage lift, with water pump main shaft, water pump in water pump part such as piece housing form.30 meters of single-stage lift and 40 meters two kinds of impellers that flow is identical of single-stage lift, require to make up according to exit of pump pressure, be installed on the same water pump main shaft, 30 meters of single-stage lift and 40 meters two kinds of stators that flow is identical of single-stage lift, match with the same size impeller location, be installed in this position water pump in the piece housing.
The present invention compare with existing product its effect mainly be presented as following some: (1), meet the requirement of user and fire codes, water pump can carry out the discharge pressure stepping for 10 meters by every grade of lift; (2), the combination of selecting 30 meters of single-stage lift and 40 meters two kinds of specification impellers for use, between pump capacity 10L/S～40L/S, can adopt the high-speed, multi-stage centrifugal water pump; (3), compare pump efficiency with low speed multi-stage centrifugal pump prototype and can improve 2%～5%, performance is compared pump efficiency and can be improved 5%～8% with low speed multi-stage centrifugal pump prototype impeller cutting or after departing from the rated point type selecting, can save the daily cost of use of user significantly; (4), compare the water pump diameter with the low speed multi-stage centrifugal pump and reduce approximately 20%, it is about 30%～50% that progression reduces, and can reduce the water pump volume significantly, alleviates water pump weight, reduce water pump manufacturing, transportation and installation cost; (5), adopt the 30 meters impellers identical with the stage casing of single-stage lift and the various combination of stator, product component highly versatile, water pump production management convenience with 40 meters identical, supporting main shafts of two kinds of flows of single-stage lift.
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Fig. 1 is the structural representation of the embodiment of the invention.
In embodiments of the present invention: the 1st, water pump main shaft figure; The 2nd, 30 meters impeller figure of single-stage lift; The 3rd, 30 meters stator figure of single-stage lift; The 4th, 40 meters impeller figure of single-stage lift; The 5th, 40 meters stator figure of single-stage lift; The 6th, piece housing figure in the water pump; The 7th, flat key figure.30 meters impellers of single-stage lift (2), (4) two kinds of impellers that flow is identical of 40 meters impellers of single-stage lift are installed on the same water pump main shaft (1) by flat key (7); 30 meters stators of single-stage lift (3), (5) two kinds of stators that flow is identical of 40 meters stators of single-stage lift match with the same size impeller location, are installed in this position water pump in the piece housing (6).
