Description
Technical field
The utility model discloses a kind of pump, especially disclose a kind of two suction port volute pump.
Background technique
Volute pump is that the mankind carry flowing material important tool.But because the reason of volute pump structure, segment fluid flow returns in volute pump by the gap location of impeller and spiral initial part that being formed circulates leaks, thus causes the consumption of wattless power, the power of increase needed for volute pump.Especially chemical industry user generally uses is all centrifugal pump in industrial or agricultural in addition, centrifugal pump is bulky, inefficiency, fluid causes pump housing internal pressure to strengthen power consumption seriously at pump housing Inner eycle, and impeller blocks the water pump caused phenomenon of not doing work and often occurs, cause puzzlement economically to industrial and agricultural production.
Model utility content
The utility model overcomes the deficiency that prior art exists, and aims to provide a kind of two suction port volute pumps of efficient, energy-conservation, long service life.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of two suction port volute pump, and comprise the pump housing, the described pump housing comprises body, described body is the cylindrical chamber of hollow, and outside described body, two ends are respectively installed with two annular hollow heat radiation oil boxes; The two ends of body are equipped with end cap, the center of described two end caps is coated with screw rod, described screw rod wherein side passes from end cap and is coated with small end cover, buffer is provided with in the middle of screw rod, screw rod is coated with two fans near two end caps, screw rod is placed in intrinsic part and is provided with helical blade, and described helical blade extends to buffer from both sides fan respectively; Outside described body, neutral position is provided with outlet, and below body, two bases are equipped with at two ends respectively.
Be provided with to be connected with heat radiation oil box inside exhaust port and oil hole above described heat radiation oil box, described exhaust port is connected with one end of outlet pipe, and the other end of described outlet pipe is with body and be connected with body interior, is provided with oil extraction bolt below heat radiation oil box.
The utility model compared with prior art has following beneficial effect:
1, efficient, energy-conservation.Compared with prior art, the utility model has two suction port, and fluid sucks from pump housing two ends suction port, and working efficiency is high.
2, long service life.In the utility model, fluid sucks from pump housing two ends suction port, solves the work done of centrifugal pump body two ends uneven, and the problem that torsion strengthens extends working life.
Accompanying drawing explanation
Fig. 1 is a kind of two suction port volute pump sectional drawing.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of two suction port volute pump, comprise the pump housing 1, the pump housing 1 comprises body 2, and body 2 is the cylindrical chamber of hollow, and outside body 2, two ends are respectively installed with two annular hollow heat radiation oil boxes 3; The two ends of body 2 are equipped with end cap 4, the center of two end caps 4 is coated with screw rod 5, screw rod 5 wherein one end passes from end cap 4 and is coated with small end cover 11, buffer 6 is provided with in the middle of screw rod 5, screw rod 5 is coated with fan 7 respectively near two end caps, screw rod 5 is placed in the part in body 2 and is provided with helical blade 8, and helical blade 8 extends to buffer 6 from both sides fan 7 respectively; Outside body 2, neutral position is provided with outlet, and below body 2, base 10 is equipped with at two ends respectively.Fluid sucks from the pump housing 1 two-port, and double helix supercharging makes the pump housing 1 fluid pressure be concentrated to central exit 9 output fluid.Alleviate the pressure at the pump housing 1 two ends, and owing to being threaded through the pump housing, in acting process, avoid the phenomenon of centrifugal pump impeller blocking.
To be connected with heat radiation oil box inside exhaust port 21 and oil hole 23 is provided with above heat radiation oil box 3, exhaust port 21 is connected with one end of outlet pipe 22, the other end of outlet pipe 22 is connected with body 2 and is connected with body 2 inside, is provided with oil extraction bolt 24 below heat radiation oil box 3.
The foregoing is only preferred embodiment of the present utility model; be not limited to the utility model; although be described in detail the utility model with reference to previous embodiment; for a person skilled in the art; it still can be modified to the technological scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
