Abstract
The utility model relates to the technical field of the class of mechanical engineering pumps, which is used for conveying liquid media. The utility model is characterized in that a motor 11 is arranged above a pump body 1 and is in a vertical structure; an impeller 2 is arranged on a pump shaft 4; a bearing 5 is fixed on the pump shaft 4 by a shaft shoulder on the pump shaft 4 and a fastener 6 and is fixed in a pump cover 3 by a bearing press cover 7; the pump cover 3 is a supporting body of the bearing 5 and is a static ring seat of a mechanical seal 14; the pump cover 3 and a motor bracket 13 are respectively and directly connected above the pump body 1 by connecting pieces; a rigid detachable shaft coupling 9 is arranged between a shaft coupling 8 of the pump and a shaft coupling 10 of the motor; the lateral surface of the motor bracket 13 is provided with a large hole 12 for the motor bracket. Through tests, the new structure is very reasonable and satisfies the requirement of a standard universal motor matching the pump, and the new structure takes convenience for the maintenance of the pump.
Description
The utility model relates to mechanical engineering pump class technical field, is applied to liquid and carries.
Existing ISG type vertical single stage centrifugal pump, adopt the motor of extension shaft, pump impeller is contained on the lengthening end of motor reel, though this pump structure is simple, but there is following problem: 1., bring inconvenience for production and maintenance because motor is the nonstandard definite-purpose motor of extension shaft.2. when changing pump easily damaged parts and impeller, must the dismounting motor, when the auxiliary motor power of pump is big, keep in repair very difficult.
The purpose of this utility model provides a kind of planning standard general-purpose motor, need not dismantle the vertical centrifugal pump of motor during maintenance.
The purpose of this utility model is achieved in that
That is: impeller 2 is installed on the pump shaft 4, and bearing 5 is fixed on the pump shaft 4 by the shaft shoulder on the pump shaft 4 and fastening piece 6, and is fixed in the pump cover 3 by bearing gland 7.The detachable coupling 9 of rigidity is housed between pump coupling 8 and motor coupler 10, like this motor 11 can be supporting be the standard universal motor.Pump cover 3 promptly is the supporting mass of bearing 5, also is the stationary seat of mechanical seal 14, and pump cover 3 and electric machine support 13 directly are connected in the top of the pump housing 1 respectively by coupling.The side of electric machine support 13 has a macropore 12, after tearing the but detachable coupling 9 of rigidity and the coupling that is connected the pump housing 1 and pump cover 3 open, need not dismantle motor 11, pump cover 3 and pump rotor parts can be taken out from electric machine support macropore 12, equally also they can be reinstalled the original place.Motor 11 is vertical structure above the pump housing 1.
Concrete structure of the present utility model is provided by the following drawings and embodiment.
Fig. 1 is the utility model complete machine structure schematic representation.
Now describe the utility model concrete structure in conjunction with the accompanying drawings in detail:
As shown in Figure 1, this vertical centrifugal pump is made up of the pump housing 1, impeller 2, pump cover 3, pump shaft 4, bearing 5, fastening piece 6, bearing gland 7, pump coupling 8, the detachable coupling 9 of rigidity, motor coupler 10, motor 11, electric machine support macropore 12, electric machine support 13, mechanical seal 14.Wherein the pump rotor parts comprise: impeller 2, bearing 5, fastening piece 6, pump coupling 8, mechanical seal 14.
It is characterized in that: motor 11 is vertical structure above the pump housing 1; Impeller 2 is installed on the pump shaft 4; Bearing 5 is fixed on the pump shaft 4 by the shaft shoulder on the pump shaft 4 and fastening piece 6, and is fixed in the pump cover 3 by bearing gland 7; Pump cover 3 is the supporting mass of bearing 5, also is the stationary seat of mechanical seal 14; Pump cover 3 and electric machine support 13 directly are connected in the top of the pump housing 1 respectively by coupling; The detachable coupling 9 of rigidity is housed between pump coupling 8 and motor coupler 10; The side of electric machine support 13 has an electric machine support macropore 12.
The utility model has the advantages that: 1. motor 11 can adopt the standard universal motor. 2. pull down rigidity Detachable shaft coupling 9, and after connecting the connector of the pump housing 1 and pump cover 3, need not dismantle motor 11, Pump cover 3 and pump rotor parts can be taken out from the macropore 12 of electric machine support 13, they can be filled equally Reposition, it is very convenient that pump is maintained.
