Abstract
The utility model discloses a direct-coupled centrifugal pump with a bearing, which mainly comprises a pump body, an impeller, a pump cover, a motor, a connecting rack and a pump shaft. An impeller is mounted on the pump shaft and positioned in a pump body groove; the pump cover is connected to the right end of the pump body; one end of the connecting rack is connected with the pump cover; the other end of the connecting rack is connected with the motor; the pump shaft is connected with a motor spindle; the bearing is mounted on the pump shaft and clamped in the groove of the connecting rack; and an axial contact surface of the bearing with the groove of the connecting rack is provided with an elastic washer. The bearing arranged on the pump shaft functions in support, radial runout of the impeller can be limited, the axial contact surface of the bearing with the groove of the connecting rack is provided with the elastic washer for effectively reducing vibration of the pump in running, abrasion of the pump is decreased, and the service life of the pump is prolonged. To sum up, the direct-coupled centrifugal pump with the bearing is simple in design structure, long in service life, convenient in operation and suitable for popularization.
Description
Technical field
The utility model relates to the pumping unit field, refers more particularly to the centrifugal pump that a kind of straight connection type tape spool holds.
Background technique
Known centrifugal pump mainly includes the pump housing 1, impeller 4, pump cover 7, motor 10, hitch 12, pump shaft 15 as shown in Figure 1.Being connected and can further being subdivided into two kinds of structures according to motor and axle: a kind ofly be shared one of motor and pump, this structural imperfection is that then pump just can not use if motor damages, and versatility is poor, and motor need be special, and the pump installation and maintenance bother; And noise vibration is bigger, and during pump operation, radial force is bigger, thereby accelerates the wearing and tearing of pump.Another kind is not connected for motor shaft has bearing with pump shaft, this structural imperfection is pump shaft and motor shaft attachment portion, does not have the bearing supporting, under rotating speed one stable condition, increase along with the motor output power, not radially not locating of axle, the circular runout meeting increases gradually, and the moment of torsion of axle can become big, dangerouse cross-section is disconnected easily, the operational shock noise also can be bigger, also can accelerate the wearing and tearing of pump, and the life-span is shorter.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art and provides a kind of simple in structure, realizes low cost, long service life, the centrifugal pump that novel straight connection type tape spool easy to maintenance holds.
The utility model is realized in the following way, mainly includes the pump housing, impeller, pump cover, motor, hitch, pump shaft, and wherein: impeller is installed on the pump shaft, and is positioned at pump housing groove; Pump cover is connected in pump housing right-hand member; Hitch one end is connected with pump cover, and the other end is connected with motor; Pump shaft is connected with electric machine main shaft;
Be equiped with bearing on the described pump shaft; Described bearing is arranged in the groove of hitch; The axial surface of contact of the groove of bearing and hitch is provided with elastic washer.
Also be provided with bearing cap on the groove of described hitch.
The utility model is provided with bearing and play supporting role on pump shaft, can limit the circular runout of impeller, and the axial surface of contact of the groove of bearing and hitch is provided with elastic washer and effectively reduces the vibration of pump when operation, reduces the wearing and tearing of pump, improves the life-span.In sum, the utility model project organization is simple, long service life, easy to operate, the suitable popularization.

Fig. 2 the utility model structural representation.
Embodiment
Now in conjunction with the accompanying drawings, the utility model preferred implementation is described in detail in detail:
As shown in Figure 2, the centrifugal pump that a kind of straight connection type tape spool holds mainly includes the pump housing 1, impeller 4, pump cover 7, motor 10, hitch 12, pump shaft 15, and wherein: impeller 4 is installed on the pump shaft 15, and is positioned at the pump housing 1 groove; Pump cover 7 is connected in the pump housing 1 right-hand member; Hitch 12 1 ends are connected with pump cover 7, and the other end is connected with motor 10; Pump shaft 15 is connected with motor 10 main shafts;
Be equiped with bearing 8 on the described pump shaft 15; Described bearing 8 is arranged in the groove 121 of hitch; Bearing 8 is provided with elastic washer 13 with the axial surface of contact of the groove 121 of hitch.
The groove 121 of described hitch is provided with bearing cap 18.
The utility model is provided with bearing 15 and play supporting role on pump shaft, can limit the circular runout of impeller 4, and bearing 8 is provided with the effectively vibration of reduction pump when moving of elastic washer 13 with the axial surface of contact of the groove 121 of hitch, reduces the wearing and tearing of pump, improves the life-span.
