Description
Technical field
The utility model, which is related in novel high-efficiency and energy-saving, opens double suction centrifugal pump, belongs to centrifugal pump field.
Background technology
Can double entry pump normally run through commonly used dynamic equipment, be directly connected to the stable of whole device and cover with excellent fortune
Turn.Due to the vibration of pump, annual maintenance will put into substantial amounts of manpower and materials.Both took time and effort, and there is very big safety again hidden
Suffer from.And be many reason for cause pump vibration, it occurs with multiple factors, the superposition of many reasons and collective effect.
The pump shaft length of current existing double suction centrifugal pump is longer and pump shaft diameter is smaller, easily occurs pump shaft rigidity not
Foot, amount of deflection is too big, the situation of pump shaft system linearity difference, causes to touch between moving part (rotor part) and quiet part (sealing ring etc.)
Rub, form vibration.In addition, pump shaft is oversize, is influenceed larger by water slug is flowed in pond, makes the vibration of pump underwater portion
Increase, axial work shifting amount adjustment is improper, can cause pump shaft low frequency play.
The content of the invention
Technical problem to be solved in the utility model is：There is provided in novel high-efficiency and energy-saving and open double suction centrifugal pump, it is solved
Determined existing double entry pump pump shaft it is oversize by pond flow water slug influenceed to cause pump shaft low frequency play the problem of.
Technical problem to be solved in the utility model takes following technical scheme to realize：
Double suction centrifugal pump, including the pump housing, impeller, pump shaft, bearing gland and bearing body, the leaf are opened in novel high-efficiency and energy-saving
Wheel is fixedly connected on the middle part of pump shaft, and the pump shaft, which runs through on the pump housing, pump shaft, is provided with axle sleeve, and pump shaft two ends are socketed with bearing,
End ring is provided between the axle sleeve and bearing, the bearing gland is socketed on pump shaft, and the bearing body is arranged on pump
The top of axle, bearing body is fixed with the pump housing, and bearing gland set is fixedly connected with bearing body.
As preferred embodiment, the pump shaft and axle sleeve environmental sealing.
As preferred embodiment, on the bearing socket pump shaft and inside bearing body.
As preferred embodiment, the pump shaft, using one section of optical axis, installs position and the pump shaft of bearing between two bearings
Shoulder height degree difference 2.5mm.
The beneficial effects of the utility model are：Two bearings are set, reduce axial length, the appropriate diameter for increasing axle is carried
The high rigidity of axle, preferably ensure that the concentricity of axle, effectively reduces the vibration of pump, install the position of bearing during processing
2.5mm is highly differed with the shaft shoulder, bearing and axle sleeve can not be fixed well, bearing interstage sleeve is set between bearing and axle sleeve to consolidate
Dead axle is held and axle sleeve.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is pump body structure schematic diagram of the present utility model；
In figure：The pump housing 1, impeller 2, pump shaft 3, bearing gland 4, bearing body 5, cylindrical 6, axle sleeve 31, bearing 32, end ring
33。
Embodiment
In order to be easy to understand to technological means of the present utility model, creation characteristic, reached purpose and effect, tie below
Conjunction is specifically illustrating, and the utility model is expanded on further.
As shown in figure 1, double suction centrifugal pump is opened in novel high-efficiency and energy-saving, including the pump housing 1, impeller 2, pump shaft 3, bearing gland 4
With bearing body 5, impeller 2 is fixedly connected on the middle part of pump shaft 3, and pump shaft 3, which runs through on the pump housing 1, pump shaft 3, is provided with axle sleeve 31, pump shaft 3
Two ends are socketed with bearing 32, and end ring 33 is provided between axle sleeve 31 and bearing 32, and bearing gland 4 is socketed on pump shaft 3, axle
The top that body 5 is arranged on pump shaft 3 is held, bearing body 5 is fixed with the pump housing 1,4 sets of bearing gland is fixedly connected with bearing body 5.
Pump shaft 3 and the environmental sealing of axle sleeve 31, bearing 32 is socketed on pump shaft 3 and inside bearing body 5, pump shaft 3 is two
Using one section of optical axis between individual bearing 32, the position for installing bearing 32 differs 2.5mm with the shoulder height degree of pump shaft 3.
Set two bearings 32 to support at the two ends of pump shaft 3, reduce the length of pump shaft 3 in proper range, it is appropriate to increase
The diameter of pump shaft 3, does not increase the rigidity and rotor part balance of pump shaft 3, preferably the concentric of pump shaft 3 is ensure that during processing
Degree, effectively reduces the vibration of pump, and one section of optical axis is used between two bearings 32 in pump shaft 3, installs the position of bearing 32
2.5mm, the minimum diameter of axle and maximum diameter of axle difference very little are differed with the shoulder height degree of pump shaft 3, it is impossible to good fixing bearing 32 and axle
Set 31, by setting bearing interstage sleeve, the fixing bearing 32 that can be consolidated and axle sleeve 31 between bearing 32 and axle sleeve 31.
As shown in Figure 2：The pump housing 2 is processed the two ends of the pump housing 1 in processing, first and installed cylindrical 6 at bearing body 5, and then frock is pressed from both sides
Tool is enclosed on cylindrical 6 blending bolt of processing and fixed, it is to avoid due to fixture play in process so that processing dimension it is inaccurate and
The mismachining tolerance caused, in process, the rotary shaft of frock and the actual center line of pump shaft 3 are located at same straight line so that
The bounce of process is smaller, so as to ensure that the concentricity of the pump housing 1 and rotor part, effectively reduces pump in the running
Vibrated because of caused by mismachining tolerance.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
The technical staff of industry it should be appreciated that the utility model is not restricted to the described embodiments, do not depart from the utility model spirit and
On the premise of scope, the utility model also has various changes and modifications, and these changes and improvements both fall within claimed sheet
In the range of utility model.Scope is claimed by appended claims and its equivalent thereof in the utility model.
