Description
Technical field
The utility model is related to oil suction pump technical field, more particularly to a kind of electric-machine directly-driven horizontal centrifugal oil pump.
Background technology
Pump is trandfer fluid or makes the machinery of fluid pressurized, and it sends the mechanical energy of prime mover or other external energies to
Liquid, increases liquid energy, plays a part of conveying liquid and provides the pressure flow of chemical reaction.Accompanying drawing in specification
1 is the structural representation of single suction horizontal centrifugal oil pump, and single suction horizontal centrifugal oil pump is main by motor 1, the elastic pivot pin shaft coupling of lengthening
Device part 2, sprung parts 3, mechanical sealing parts 4, pump cover 5, impeller 6, the pump housing 7, support 8 and base 9 are constituted, and its middle (center) bearing hangs
Frame part is made up of bearing suspension, axle, bearing, bearing gland, dust pan etc., and the major defect of such a oil pump structure is：Should
The pump pump housing is split-type structural with support, bearing suspension part, joint member, pump, and tie point is excessive, makes the pump in processing
Required precision with assembling is too high, simultaneously because adding tie point, it vibrates and noise will accordingly increase, and mechanical efficiency is also same
When reduce, while also increase the difficulty and cost of making, therefore urgently design a kind of oil scavenge pump for overcoming disadvantages mentioned above.
Utility model content
In order to overcome above-mentioned existing technological deficiency, the purpose of this utility model is that providing a kind of structure simplifies, body
Product smaller, the vibration of the pump housing and a kind of electric-machine directly-driven horizontal centrifugal oil pump that noise is low and mechanical efficiency is high.
In order to achieve the above object, the utility model is achieved through the following technical solutions：
The technical program be a kind of electric-machine directly-driven horizontal centrifugal oil pump, including motor, impeller, sealing chamber, the pump housing, support and
Base, the motor is arranged on one end of base, and the support that the pump housing is then set by bottom is fixedly connected in the other end of base,
The both sides end face of the sealing chamber is fixedly connected with the flange of motor and the end face of the pump housing respectively along electrical axis line；The impeller
On the output shaft of motor, it is placed in the pump housing.This equipment is directly connected to impeller using motor output shaft, direct by motor
Impeller work is driven, bearing suspension part and its numerous parts has been saved, both having reduced tie point makes noise and vibration accordingly subtract
It is few, while reducing the required precision of part of appliance processing and assembling.
Compared with prior art, the beneficial effects of the utility model are：This oil pump employs motor-direct-drive type attachment structure,
Impeller is directly installed on the output shaft of motor, and its size is can be controlled in 1/2 length range of crude oil pump so that the profile of pump
Greatly reduced, equipment is saved using the required place space occupied, with the installation suitable for narrowly shape, simultaneously because subtracting
The drive connection of center section is lacked, has reduced vibration and the noise for oil pump of knowing clearly, reduce noise pollution, improve mechanical effect
Rate, the performance parameter of oil pump is also improved, and application is more extensive.
This programme is that other optimizations also include with preferred embodiment：1st, the pump housing and support use the integral type of monoblock cast
Structure, simplifies the production and processing technology of part, while convenient overall assembling and installation, enable overall steadiness significantly
Enhancing；2nd, the motor uses B35 type motors, and easily buying is obtained, and due to band footing, using FF flanges, is easy to the movement of motor
And installation.
Brief description of the drawings
The utility model will illustrate by example and with reference to the appended drawing, wherein：
Fig. 1 is centrifugal pump schematic diagram before improving；
Fig. 2 is the utility model structural representation.
Embodiment
Below in conjunction with the accompanying drawings, the utility model is described in detail.
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only to explain
The utility model, is not used to limit the utility model.
As shown in figure 1, the utility model is a kind of electric-machine directly-driven horizontal centrifugal oil pump, including motor 1-1, impeller 6-1, machine
Room 4-1, pump housing 7-1, support 8-1 and base 9-1 are sealed, the motor 1-1 is arranged on base 9-1 one end, defeated along motor 1-1
The axial line of shaft, a sealing chamber 4-1 side end face is fixedly mounted on flange 1-2, in sealing chamber 4-1 another side end face then
It is fixedly connected with pump housing 7-1 end face, the other end for the support 8-1 and base 9-1 that the pump housing 7-1 is set by bottom again is consolidated
Fixed connection, the impeller 6-1 is then directly installed on motor 1-1 output shaft, is placed in pump housing 7-1, passes through motor 1-1's
Operating of the output direct drive impeller in pump housing 7-1.This oil pump structure simplifies, and globality is strong after installation, reduce transmission and
The tie point of installation so that oil pump operation is more stable, vibration and noise are also accordingly reduced, and mechanical efficiency is greatly improved.
As optimization, the pump housing 7-1 and support 8-1 uses the integral structure of monoblock cast, with further increasing structure
Advantage of the globality to reduce the noise of pump operation and vibrate；The preferable B35 types motor of motor used, is easy to motor
Mobile and installation.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modifications, equivalent substitutions and improvements made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
