Detailed description of the invention
Describe this utility model below with reference to the accompanying drawings in detail.
Embodiment 1
A kind of multistage multifunctional pump for heating system, as it is shown in figure 1, include the pump shaft 2 being positioned at the pump housing 1, described pump
Axle 2 runs through the pump housing 1, and the upper end of pump shaft 2 is connected as its motor 3 providing power source, and the lower loop of pump shaft 2 is around being fixed with some levels
Impeller 9.Pump shaft 2 is used for transmitting power, supporting impeller runs well.
Described motor 3 is vertically fixed on motor cabinet 4, and motor cabinet 4 is fixed with the pump housing 1 by bracing frame 5.Motor crankshaft
It is passed down through motor cabinet 4, fixed with pump shaft 2 by shaft coupling 6, for being rigidly connected between shaft coupling 6 and pump shaft 2, it is ensured that electricity
The synchronicity that machine arbor operates with pump shaft, it is simple to Maintenance and Repair.Mechanical seal is set between motor crankshaft and motor cabinet 4, keeps away
Exempt from the liquid in the pump housing and enter motor.It is additionally provided with bearing 7 on described pump shaft 2, effectively prevents the vibrations of pump shaft, reduce friction system
Number.
Being provided with some grades of impellers 9 and stator 8 in the pump housing 1, impeller 9 is looped around pump shaft 2 lower end, and by bolt and pump shaft
2 fixing connections；Between impeller 9 and pump shaft 2, sealing gasket is set.Stator 8 is arranged on the exit of impeller 9, is formed and be used between stator
The runner of water conservancy diversion.Impeller rotates work done, drives heat supply water sport, converts kinetic energy into the static energy of water, improves the pressure of water.
The end one-level (i.e. the first order) of multifunctional pump is suction casing, and upper level (i.e. afterbody) is Spit Section, sucks
It is stage casing between section and Spit Section.Suction casing arranges the first suction inlet 10, is used for sucking heat supply water；Spit Section arranges discharge opening
12, after pressurization, discharge heat supply water；Stage casing is additionally provided with the second suction inlet 11, the second suction inlet 11 and the first suction inlet 10
Between, be the most at least spaced one-level between the second suction inlet 11 and discharge opening 12.At first suction inlet the 10, second suction inlet 11, tell
It is respectively provided with valve on the pipeline that outlet 12 is connected, the independent opening and closing of this pipeline can be realized.
In suction inlet, stage casing mouth and discharge opening, two of which is at the homonymy of the pump housing, and another is at the heteropleural of the pump housing.In this reality
Executing in example, the first suction inlet, discharge opening are arranged on the left side of the pump housing, and the second suction inlet is arranged on the right side of the pump housing.
Embodiment 2
A kind of multistage multifunctional pump for heating system, as in figure 2 it is shown, substantially similar with embodiment 1 structure, its difference exists
In: first suction inlet the 10, second suction inlet 11 is arranged at the left side of the pump housing 1, and discharge opening 12 is arranged on the right side of the pump housing 1.
Running of the present utility model is:
Starting motor, motor crankshaft drives pump shaft to rotate by shaft coupling, pump shaft impeller rotates, and heat supply water is from suction
Entrance enters the pump housing, produces lift through first order impeller work done, is introduced the water into next stage impeller by stator, at next stage impeller
Continue acting and produce lift, pressure continuation increase, move in circles, until it reaches afterbody impeller, discharge through discharge opening.
When the first suction inlet and the second suction inlet difference during work, the preferably multifunctional pump of selection embodiment 2 structure, first
Suction inlet and the second suction inlet are arranged on the homonymy of the pump housing, and discharge opening is arranged on the heteropleural of suction inlet.Raise according to actually required
Range request increase and decrease multifunctional pump progression, thus select the suction inlet being suitable for.When needs lift is low, select the first suction inlet water suction；
When the lift height needed, select the second suction inlet water suction, it is achieved a pump is multiplex, flexibly and easily.
When heat supply water is two strands and during two bursts of heat supply water pressure differences, and the first suction inlet and the second suction inlet are simultaneously
Work.Selecting suction inlet according to actual pressure, the heat supply wet concentration that pressure is little is selected the first suction inlet and is sucked, the heat supply that pressure is big
Select the second suction inlet with wet concentration to suck, it is thus achieved that two different lifts；Through the effect of multifunctional pump, the discharge pressure of discharge opening is real
Now unified, discharge pressure is above the pressure of two bursts of water inlets, reaches the pressurized effect different to two strands of heat supply water.
The foregoing is only preferred embodiment of the present utility model, all according to this utility model claim done equal
Deng change and modification, covering scope of the present utility model all should be belonged to.
