In the prior art, the vertical single stage self-priming pump is applicable to industrial and mineral enterprises and institutions such as boats and ships, building, fire-fighting, chemical industry, pharmacy, environmental protection, and confession, draining be usefulness only, Applicable scope and of many uses; Can provide the pump of unlike material according to the liquid difference of user's request or fed sheet of a media.
At present, at self-priming pump in design process, the performance setting scope is narrower, and its flow and lift are less than normal, and under the working state of self-priming pump, augmented flow and lift will cause the radial force of pump and peripheral force to increase, thereby cause spindle speed function to increase, increase load, influence the self-priming pump pump performance, influence the proper functioning of self-priming pump greatly, simultaneously self-priming pump dismounting difficulty of the prior art, take up an area of shortcomings such as the space is big.
The model utility content
Technical problem to be solved in the utility model is, under the working state of self-priming pump, augmented flow and lift will cause the radial force of pump and axial force to increase, thereby cause spindle speed function to increase, increase load, influence self-priming pump performance, dismounting difficulty, take up an area of technical problems such as the space is big, and a kind of vertical detachable type single-stage self-priming pump is provided.
Technological scheme provided by the utility model is, a kind of vertical detachable type single-stage self-priming pump comprises motor, connected body, the pump housing and driving mechanism, and described motor is arranged in the top of the described pump housing.
The top of the described pump housing is provided with electric machine support, on the described electric machine support motor is installed, and the both sides of described electric machine support are respectively arranged with water outlet and water intake.
Described driving mechanism comprises transmission shaft and the coupling between the described motor and the pump housing, and be arranged in pump housing bottom and impeller.
Impeller in described motor, transmission shaft, shaft joint and the pump housing is coaxality and installs.
A kind of vertical detachable type single-stage self-priming pump provided by the utility model, can effectively solve under the working state of self-priming pump, augmented flow and lift will cause the radial force of pump and axial force to increase, thereby cause air horsepower to increase, increase load, influence the technical problem of self-priming pump performance.While a kind of vertical detachable type single-stage self-priming pump provided by the utility model, has stronger self-absorption function, the compact structure of pump design, operate steadily, have the pipeline mounted pump characteristics different during work with self-priming pump, floor space is little, dismounting, easy to maintenance, and advantage such as efficient height, long service life, before pump work, only need to guarantee have the quantitative liquid that draws to get final product in the pump housing, need not to add again diversion; Therefore simplify pipe-line system, improved working condition again.
Description of drawings
In conjunction with the accompanying drawings, the utility model is further described;
Fig. 1 is the utility model structural representation;
Wherein, 1 is the pump housing; 2 is drain plug; 3 is impeller; 4 is return pipe; 5 are mechanical seal; 6 is transmission shaft; 7 is pump cover; 8 is bearing; 9 are the water inlet bend; 10 is outside framework oil seal; 11 is shaft joint; 12 is motor; 13 is electric machine support; 14 is bearing support; 15 is gas-liquid separation chamber.
Embodiment
In conjunction with the accompanying drawings 1, a kind of vertical detachable type single-stage self-priming pump that this practicality provided adopts the structure of axial sucking type, is made of parts such as the pump housing 1, drain plug 2, impeller 3, return pipe 4, mechanical seal 5, transmission shaft 6, pump cover 7, bearing 8, water inlet bend 9, outside framework oil seal 10, shaft joint 11, motor 12, electric machine support 13, bearing support 14, gas-liquid separation chamber 15.
A kind of vertical detachable type single-stage self-priming pump provided by the utility model comprises motor 12, connected body, the pump housing 1 and driving mechanism, and described motor 12 is arranged in the top of the described pump housing 1.The top of the described pump housing 1 is provided with electric machine support 13, on the described electric machine support 13 motor 12 is installed, and the both sides of described electric machine support 13 are respectively arranged with water outlet and water intake.Described driving mechanism comprises transmission shaft 6 and the coupling between the described motor 12 and the pump housing 1, and be arranged in the pump housing 1 bottom with impeller 3.Impeller 3 in described motor 12, transmission shaft 6, shaft joint 11 and the pump housing 1 is coaxality and installs.
A kind of vertical detachable type single-stage self-priming pump provided by the utility model adopts vertical structure, and Installation and Debugging are convenient, the motor 12 of unique design adopts coupling to be connected concentricity height, machining accuracy height with the pump housing 1, dwindled the occupation of land space greatly, footing is firm, compact structure.
Adopt separate bearings body 14 pump shafts to support, solved the deficiency that original vertical pump supports by motor 12 extension shafts.
Bearing 8 adopts precision bearings 8, and precision height, good reliability, life-span are long;
