Abstract
The utility model relates to a vertical open type axial flow pump, which is a novel pump with the two-way running mode of pump drainage and pump drawing. The utility model belongs to the field of the mechanical technology. A water outlet diffusion tube is mainly installed on a guide blade body. A water outlet flow guiding body is installed on the concrete base bottom of a water outlet flow passage. The utility model has the advantages of simple structure, reliable performance, convenient installation, and convenient inspection and repair. Proper two-way water inlet flow passage, a water outlet flow passage and a gate are matched with the original pump shaft. The rotation direction of a pump is not changed. The switching over of the forward and reverse direction of the water flow can be conveniently realized through the control of the gate on the water inlet flow passage and the water outlet flow passage. The forward and reverse running properties are consistent.
Description
A kind of vertical open type axial-flow pump is a kind ofly to have pump drainage, take out the new pump of drawing way traffic, belongs to field of mechanical technique.
Before the utility model was made, conventional vertical-type axial-flow pump mainly was made up of motor, Discharging bent-tube, pump shaft, impeller, diffuser, impeller housing.Pump shaft is connected on the motor, and impeller is installed on the pump shaft, and diffuser is installed on the water pump layer concrete basis, and impeller housing is installed in the diffuser bottom, and bend pipe is installed in diffuser top.This kind structure can not realize the forward and reverse switching of current easily, can not satisfy the requirement of two-way pump drainage water.
The purpose of this utility model is to overcome above-mentioned deficiency, thus provide a kind of simple in structure, in the sense of rotation that does not change pump, by the gate on inlet and outlet channel control, can realize the vertical open type axial-flow pump of forward and reverse switching of current easily.
The main solution of the utility model is achieved in that its mainly installation water outlet diffusing tube 5 on diffuser 4, and water outlet deflector 6 is installed in outlet passage concrete foundation bottom.
Description of drawings:
Fig. 1 is the utility model structural front view:
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
Pump shaft 7 is connected on the motor 10, and impeller 3 is installed on the pump shaft 7, and diffuser 4 is installed in above the water pump layer concrete basis, and impeller housing 2 is installed in diffuser 4 bottoms.Water outlet diffusing tube 5 is installed in diffuser 4 tops, water inlet water guide cone 1 is installed in on the water concrete, top cover 8 is installed in above the sealing layer outlet passage concrete foundation, and packing seal 9 is installed on the top cover 8, and water outlet deflector 6 is installed in outlet passage concrete foundation bottom.
Motor is by the pump shaft impeller, impeller is rotated in impeller housing, to the water work done, the water energy is increased, thereby make the water of requirement, be transported to the eminence of requirement by the priming reservoir through the flow passage components of pump, the effect of diffuser is that the rotation function with water is converted into the pressure energy, makes pump have higher hydraulic efficiency.Because the Discharging bent-tube of conventional vertical-type axial-flow pump has been removed in the water part, water outlet diffusing tube and water outlet deflector have been increased, the geometrical shape of its water part, be equivalent to be inverted bell runner, water outlet flow section area evenly enlarges along water (flow) direction, thereby current are evenly slowed down, and make current more smooth-going, in an orderly manner along the water outlet diffusing tube mouth of pipe to around flow out, reduce the local hydraulic loss at pump discharge place, improve the efficient of pump.Water inlet portion changes the metal loudspeaker water inlet of conventional axial-flow pump the water inlet of into runner concrete loudspeaker, and set up into water water guide cone in the loudspeaker bottom, its water inlet portion geometrical shape is equivalent to two bell water inlet flow channels of having got through to piecing together, and can make the current not have whirlpool, all flows into water pump.It is metal construction that the top of water inlet water guide cone changes concrete structure for one section.Like this, can adjust the height and the radial missing of water inlet water guide cone.
Compared with the prior art the utility model has the following advantages: 1, simple in structure, dependable performance makes With easy for installation; 2, mix suitable two-way inlet and outlet channel and gate at original pump, do not change pump Direction of rotation by the control of the gate on the inlet and outlet channel, can realize easily that the forward and reverse of current cuts Change, and forward and reverse runnability is consistent; 2, under the condition of not getting rid of water inlet flow channel ponding, can Carry out the mounting or dismounting of pump; Impeller shaft, diffuser and impeller housing can whole hang out from motor.
