Abstract
The utility model discloses a novel major axis pump which comprises a pump casing and a pump rack; a water inflow end and a water outlet are formed on the pump casing, and a pump shaft is mounted in the pump casing. The novel major axis pump is characterized in that multi-level straight pipes and an air directors are mounted in series sequentially at the water inflow end; multi-level transitional shafts are connected in series sequentially at the front end of the pump shaft; the pump shaft and the transitional shafts, as well as adjacent transitional shafts adopt coupler connection; a bearing base support is mounted between each transitional shaft and each straight pipe; each air director takes the shape of a bowl; an impeller seat is mounted on each transitional shaft in each air director; a blade is arranged on each impeller seat, and the blades are arranged at the front ends of adjacent air directors; and a water inflow bell mouth is mounted at the front end of the top air director. The utility model has the advantages that the maximum flow rate of the major axis pump can reach 5900m3/h, and the pumping head can reach 365m, the sealing performance is further improved, and the pump can operate stably for a long term.
Description
Technical field
The utility model belongs to a kind of pump, specifically is a kind of novel major axis pump.
Background technique
The major axis pump is to adopt multi-stage impeller, water lift lift height, and pump housing radial dimension is little, and suitable down-hole water lift is widely used in north life water lift.But because pump housing radial dimension is too small, the peak rate of flow of pump is less, and is Pump for well, is not suitable for various places.It is bad that existing pump exists sealability, wear-resisting bad with decay resistance.
The model utility content
The purpose of this utility model provides a kind of novel major axis pump, and peak rate of flow can reach 5900m3/h, and lift is up to 365m, and sealability further improves, and the pump long-time running is steady.
The technical solution of the utility model is as follows:
A kind of novel major axis pump, comprise pump case, pump bracket, feed-water end, water outlet are arranged on the pump case, pump shaft is installed in the pump case, it is characterized in that: described feed-water end be installed in series successively multistage straight tube, fluid director, described pump shaft front end is connected in series with multistage transition axis successively, between pump shaft and the transition axis, all adopt coupling to be connected between the adjacent transition axis, bearing spider is installed between described each transition axis and the straight tube supports; Described fluid director is a bowl-type, is positioned on the transition axis of each fluid director impeller base is installed, and on the described impeller base blade is installed, and described blade is positioned at the front end of adjacent fluid director; The fluid director front end at described top is equipped with into water horn mouth.
Described a kind of novel major axis pump, it is characterized in that: described blade outer wall is provided with the epoxy coating.
Described a kind of novel major axis pump is characterized in that: be separated with guide bearing between described impeller base and the pump shaft.
Its peak rate of flow of the utility model can reach 5900m
3/ h, lift are up to 365m, and sealability further improves, and the pump long-time running is steady.
