Abstract
The utility model discloses a horizontal axial-flow pump. The horizontal axial-flow pump comprises a water pump body and a water pump shaft penetrating through the water pump body. An impeller and a drive motor are fixed to the water pump shaft, wherein the drive motor is connected with the water pump shaft through a coupler, and the water pump shaft is parallel to the horizontal plane. The problem of low efficiency of the water pump at low lift is completely solved by installing the axial-flow pump in a horizontal mode; when the lift ranges from 1.5m to 5m, the efficiency can reach more than 85% by using a suitable hydraulic model and is improved by at least 10% compared with that of a vertical pump; meanwhile, the series of problems that an excavation depth is too large, a pump house is too high, the power of a matched motor is increased and manufacturing cost is high are solved.

But the problem that this structure exists is:
There is the engineering of the actual use of water pump rated lift between 1.5-5 rice in the regions such as first, China Guangdong, Jiangsu, Zhejiang, because of there is no better scheme, can only use existing vertical-type axial-flow pump, but this just to have caused water pump be to depart from operating mode to move always, inefficiency;
The second, the axial-flow pump of vertical installation is very dark because the enough depth of immersions of needs dig the degree of depth under requiring, and civilwork engineering quantity is huge, and engineering cost is very high;
Three, because pump housing length is longer, the sling height of crane is had relatively high expectations, and then the height of pump house will correspondingly increase, and increases pumping plant construction cost;
Four, due to for a long time in fallback, necessary electromotor increased power, consumes energy very large.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of horizontal axial-flow pump, and drive motor and horizontal plane are horizontally disposed with, low lift;
And pump body structure is divided into half structure up and down simultaneously, for the operation between installation period offers convenience, for the maintenance after building up is provided convenience, only need open upper half part can keep in repair, change easily damaged parts, and maintenance cost has also reduced many.
For achieving the above object, the technical solution of the utility model is as follows:
A horizontal axial-flow pump, comprising:
One water pump body,
One runs through the water pump spindle of water pump body, is fixed with an impeller on described water pump spindle,
One drive motor, described drive motor connects water pump spindle by coupling,
Described water pump spindle and horizontal plane are arranged in parallel.
Preferably, described water pump body consists of dismountable charging pump body and lower water pump body, between described charging pump body and lower water pump body, by a fixing bolt, is fixedly connected with.
Preferably, described charging pump body connects a delivery chamber, and lower water pump body connects a suction chamber, and described charging pump body is horn-like.
Preferably, on described water pump spindle and near shaft coupling side, be provided with a bearing housing.
Preferably, on described water pump spindle and near impeller side, be provided with guide bearing.
By technique scheme, the beneficial effects of the utility model are:
Adopt horizontal installation axial-flow pump thoroughly to solve the inefficiency problem of water pump when low lift, using suitable hydraulic model to meet lift efficiency when 1.5-5 rice can reach more than 85%, compare and at least improve 10 percentage points with use vertical pump, solved cutting depth excessively dark simultaneously, pump house excessive height, necessary electromotor power strengthens, high cost series of problems.
