Abstract
The utility model relates to a centrifugal multi-channel impeller water pump which is suitable for the sewage discharge of solid suspended substances. The problem of dynamic balance of the single channel impeller water pumps in the prior art can not be solved, which causes mechanical vibration and abrasion. The centrifugal multi-channel impeller water pump uses more than two channels arranged symmetrically to drive centrifugal force produced in operation to tend to be balanced, so that the mechanical vibration and abrasion are decreased. The utility model simplifies manufacturing process, and the efficiency reaches to 70%.
Description
The utility model relates to the centrifugal channel-type impeller of a kind of non-transfiguration water pump, particularly a kind of multi-channel type Effective Non-clogging Pump.Be applicable to the effluent discharge that contains suspended solid.
The water pump that is used for effluent discharge at present mostly is centrifugal rectangle impeller water pump, and its inlet/outlet diameter is little, stop up easily, and efficient only is about 50%.Recently the single channel impeller of introducing from West Germany Ritz company does not efficiently have the obstruction submerged pump.This pump has a channel-type impeller on rotor body, sewage enters impeller along rotor axial, and through the rotary centrifugal force effect, the high pressure water body sprays from outlet along the rotating shaft hoop through passage.It is big that this channel-type sewage pump is imported and exported aisle spare, is difficult for stopping up, and its efficient can reach 70%, is a kind of more rising pump.But the single channel impeller of this pump produces great centrifugal force when rotated, thereby causes the dynamic unbalance of complete machine, makes the rotating shaft serious wear, and batch process has been proposed higher technological requirement.Simultaneously, in order to enlarge the using scope of this pump, also must change it into horizontal pump, so, dynamic unbalance problem to pump has proposed higher technological requirement, through test determination, and this horizontal single channel impeller sewage pump, exist problems such as serious vibration, noise, leakage and damage in impeller, cause horizontal passage impeller sewage pump to produce in batches.
The utility model provides a kind of multichannel impeller water pump at above-mentioned deficiency, the purpose of solve dynamic unbalance to reach, improving the complete machine performance.
The technical solution of the utility model is to solve like this: change the impeller of single passage into two impellers with upper channel, passage is symmetrical distribution, and each passage is same import, and sewage sprays from the outlet port at a high speed under centrifugal action after entering each bar passage.Produce centrifugal force owing to two with upper channel while load, thus can keep its dynamic balance effectively, thus reduce problems such as vibration and damage in impeller.Consider production technology and manufacturing, passage is comparatively suitable with 2～4, can meet the blowdown requirement like this, can solve dynamic equilibrium problems again and raises the efficiency.
Provide embodiment below in conjunction with accompanying drawing.
Fig. 1 is the utility model embodiment Twin channel impeller generalized section.
Fig. 2 is the utility model embodiment Twin channel impeller schematic diagram.
With reference to Fig. 1, Fig. 2, symmetry has two blades that are equal to 2 on impeller 1, and blade 2 direct-axis are to twist, and two passages 4 connect to same import 3, are space development with cylindrical body or cone.During work, the impeller of high speed rotating is thrown to pump outlet at a high speed with the sewage in the passage, because two passages while load, and be symmetrically distributed, make complete machine keep dynamic balancing, thereby reduced vibration and damage in impeller, and can prevent from effectively to leak.
The passage of the utility model impeller also can be designed to 3,4, is symmetrically distributed around main shaft, and physical dimension is identical.Be fit to submersible type, horizontal, vertical water pump simultaneously.
The utility model manufacturing process is easy, and behavior in service is stable, has effectively overcome mechanical oscillation and wearing and tearing that the single channel impeller causes because of unbalance dynamic, and keeps efficient to reach 70%, is suitable for batch production, has obvious practical value.
