Description
Technical field
The utility model relates to liquor pump technical field, specifically, relates to a kind of vertical single-stage fire pump.
Background technique
Fire water pump, for ensureing the water yield and the hydraulic pressure of fire-fighting water, relates to personal safety and property protection, must be reliable.Vertical single-stage fire pump is as the one in fire water pump, and its working principle is as follows: motor provides powered rotor to rotate by power supply, thus the hydraulic pressure improving water in pump is delivered to piping network.But, when electric motor starting rotates, the rotor of electronics inside, motor cavity, axle all can produce larger heat, described heat mainly relies on and is transmitted on housing fins, axle, bearing, rotor and other adjacent cooperation Component, although the radiating fin heat on housing can be eliminated by the wind energy that axle produces during fan blade synchronous rotary, but the bearing of motor internal, axle, rotor heat are more than at least two to three times of outside temperature, heat is difficult to eliminate consequently motor internal and easily burns out.
In the prior art, normally adopt in the perforate of axle intermediate portion, form cold-water interior by the inner cold water one-in-and-one-out of pump chamber to circulate, make the heat of axle intermediate portion be brought into pump chamber and realize heat radiation, but there is water flow that rotary shaft hole is vulnerable to pump chamber inside and form blocking and rot in this kind of type of cooling, axle medium temperature is still higher, easily produces axial force and causes the problems such as shaft bending, fracture, the lost of life, so that have impact on the normal operating efficiency of fire water pump, and define pump chamber secondary pollution.
Model utility content
For the problems referred to above that prior art exists, the purpose of this utility model is to provide a kind of vertical single-stage fire pump, to solve axle and the slow problem of motor internal heat dissipation rate, to extend electrical machinery life, stop the situations such as axis hole blocking, bending, fracture, reduce secondary pollution, increase work efficiency.
For achieving the above object, the utility model adopts following technological scheme:
A kind of vertical single-stage fire pump, comprise motor and the pump housing, described motor comprises housing, stator, rotor and rotating shaft, described stator, rotor and rotating shaft concentric are arranged in described housing, the two ends of described rotating shaft stretch out in outside described housing, and the upper end of described rotating shaft is connected with fan blade, lower end is connected with impeller; It is characterized in that: be provided with selfsealings pipeline in the inside of described rotating shaft, in described selfsealings pipeline, be provided with conduction oil.
As a kind of preferred version, described selfsealings install pipeline, in the axle center portion of rotating shaft inside, does not contact with rotating shaft cross section.
As a kind of preferred version, between described rotating shaft and the described pump housing, be provided with mechanical seal.
As a kind of preferred version, the rotating shaft between the described pump housing and housing is provided with water retaining ring.
As a kind of preferred version, described fan blade connects described rotating shaft by jump ring.
As a kind of preferred version, the described pump housing is provided with outlet valve.
Compared to prior art, Advantageous Effects of the present utility model is:
Due to the vertical single-stage fire pump that the utility model provides, by arranging selfsealings pipeline in the inside of machine shaft, in selfsealings pipeline, conduction oil is set, thus the heat of rotating shaft inside under making working state is transmitted to low temperature area, two ends by conduction oil by central high temperature district, realize fast cooling, motor is effectively avoided to burn out, not only extend motor working life, the problems such as rotary shaft hole blocking, shaft bending, rotating shaft fracture can be stopped, and the secondary pollution can avoiding pump, there is obvious use value.
Accompanying drawing explanation
The structural representation of a kind of vertical single-stage fire pump that Fig. 1 provides for the utility model;
Number in the figure is schematically as follows: 1, motor; 11, housing; 12, stator; 13, rotor; 14, rotating shaft; 2, the pump housing; 3, fan blade; 4, impeller; 5, selfsealings pipeline; 6, conduction oil; 7, mechanical seal; 8, water retaining ring; 9, jump ring; 10, outlet valve.
Embodiment
Below with reference to accompanying drawing, description clear, complete is further done to the technical solution of the utility model.
As shown in Figure 1, a kind of vertical single-stage fire pump that the utility model provides, comprise motor 1 and the pump housing 2 two parts, described motor 1 comprises housing 11, stator 12, rotor 13 and rotating shaft 14, stator 12, rotor 13 and rotating shaft 14 concentric are arranged in housing 11, the two ends of rotating shaft 14 stretch out in outside housing 11, the upper end of rotating shaft 14 is connected with fan blade 3, the lower end of rotating shaft 14 is connected with impeller 4, the inside of rotating shaft 14 is provided with selfsealings pipeline 5, in described selfsealings pipeline 5, is provided with conduction oil 6.
Heat is produced when rotating shaft 14 rotates, the formation high-temperature zone, center portion of rotating shaft 14, and the two ends of rotating shaft 14 are respectively because the liquid cooling in fan blade 3 and the pump housing 2 forms low temperature area, now conduction oil 6 can be formed centrally convection circulation automatically in rotating shaft 14, the heat in center portion is brought into the low temperature area at two ends, thus reach cooling-down effect.Because conduction oil 6 is sealed in the selfsealings pipeline 5 of rotating shaft 14 inside, therefore, holoaxial section, motor internal cooling-down effect can not only be improved, eliminate the situations such as axial force, bending, fracture, and the secondary pollution can stopped pump, both can extend motor working life, the stability and safety high-efficiency operation of described fire water pump can have been ensured again.In addition, because a conduction oil oiling is long for service time, therefore also have without the need to keeping in repair plug-hole, installing the advantages such as simple and convenient.
Preferably:
Described selfsealings pipeline 5 is arranged on the axle center portion of rotating shaft 14 inside, does not contact with the cross section of rotating shaft 14, to form independently inner seal region, to improve cooling-down effect.
Between described rotating shaft 14 and the described pump housing 2, be provided with mechanical seal 7, the rotating shaft between the described pump housing 2 and housing 11 is provided with water retaining ring 8, inner to prevent the liquid in the pump housing 2 from entering motor 1.
