Abstract
The utility model discloses a centrifugal pump which comprises a pump body, an impeller assembly, a pump cover, a support, a bearing box, a coupling and a motor. The impeller assembly comprises a shaft, an impeller, a shaft sleeve, a moving ring, a stationary ring and a machine sealing gland, the impeller is arranged on the end portion of the shaft, the shaft sleeve, the moving ring, the stationary ring and the machine sealing gland are arranged in a cavity formed by the pump cover and the support, the machine sealing gland is connected with the pump cover, the stationary ring and the moving ring are arranged on the two sides of the machine sealing gland respectively, a space containing the stationary ring is formed between the machine sealing gland and the pump cover, and the moving ring is arranged on the side, opposite to the bearing box, of the machine sealing gland. Through the structure, the centrifugal pump is convenient to maintain, the workload of maintenance personnel can be reduced, and maintenance cost can be lowered.
Description
Technical field
The utility model relates to pump, relates in particular to a kind of centrifugal pump.
Background technique
Existing centrifugal pump comprises the pump housing, impeller assembly, pump cover, support, bearing housing, coupling and motor, the impeller assembly comprises axle, impeller, axle sleeve, rotating ring, stationary ring and machine sealed cover, impeller is positioned at the end of axle, the machine sealed cover is connected with pump cover, between machine sealed cover, pump cover, form enclosed space, stationary ring and rotating ring are positioned at this enclosed space, the position of machine sealed cover is near bearing housing, rotating ring and stationary ring are loaded on axle sleeve, the position of rotating ring and stationary ring is that rotating ring and impeller are nearer, stationary ring and bearing housing are nearer, and stationary ring and rotating ring are called mechanical seal.Such structure, after centrifugal pump uses the long period, break down, and needs repairing while changing component, takes away support, and stationary ring and rotating ring are also in pump cover and machine sealed cover, and maintenance is inconvenient, and maintenance man's workload is larger, and maintenance cost is higher.
The model utility content
Technical problem to be solved in the utility model is: a kind of centrifugal pump is provided, and this kind centrifugal pump is convenient to maintenance, can reduce maintenance man's workload, reduces maintenance cost.
Solve this technical problem, the technical solution of the utility model is: a kind of centrifugal pump, comprise the pump housing, the impeller assembly, pump cover, support, bearing housing, coupling and motor, the impeller assembly comprises axle, impeller, axle sleeve, rotating ring, stationary ring and machine sealed cover, impeller is positioned at the end of axle, described axle sleeve, rotating ring, stationary ring and machine sealed cover are positioned at the cavity of pump cover and support formation, described machine sealed cover is connected with pump cover, described stationary ring and rotating ring lay respectively at the both sides of machine sealed cover, between described machine sealed cover and pump cover, has the space of placing stationary ring, described rotating ring be positioned at the machine sealed cover towards bearing housing one side.
Described machine sealed cover is discoid, has uniform screw mounting hole on described machine sealed cover.
A kind of centrifugal pump of the utility model adopts such structure, compared with prior art, and the shorten length of pump cover, the volume of stationary ring, rotating ring increases, the volume of machine sealed cover reduces, rotating ring be positioned at the machine sealed cover towards bearing housing one side, during maintenance, take away support, just can observe directly rotating ring, the machine envelope is revealed very clear, is convenient to maintenance, can reduce maintenance man's workload, improve maintenance work efficiency, reduce maintenance cost.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, a kind of centrifugal pump of the utility model is described in further detail;
Fig. 1 is the structural representation of a kind of centrifugal pump of the utility model;
In Fig. 1,1, the pump housing; 2, pump cover; 3, support; 4, bearing housing; 5, coupling; 6, motor; 7, axle; 8, axle sleeve; 9, rotating ring; 10, machine sealed cover; 11, stationary ring; 12, impeller; 13, base.
Embodiment
As shown in Figure 1, a kind of centrifugal pump, comprise base 13, the pump housing 1, the impeller assembly, pump cover 2, support 3, bearing housing 4, coupling 5 and motor 6, the pump housing 1, the impeller assembly, pump cover 2, support 3, bearing housing 4, coupling 5 and motor 6 are placed on base 13, the impeller assembly comprises axle 7, impeller 12, axle sleeve 8, rotating ring 9, stationary ring 11 and machine sealed cover 10, impeller 12 is positioned at the end of axle 7, axle sleeve 8, rotating ring 9, stationary ring 11 and machine sealed cover 10 are positioned at the cavity of pump cover 2 and support 3 formation, machine sealed cover 10 is connected with pump cover 2, stationary ring 11 and rotating ring 9 lay respectively at the both sides of machine sealed cover 10, between machine sealed cover 10 and pump cover 2, has the space of placing stationary ring 11, rotating ring 9 be positioned at machine sealed cover 10 towards bearing housing 4 one sides, rotating ring 9 matches with stationary ring 11.Machine sealed cover 10 is discoid, on machine sealed cover 10, has uniform screw mounting hole.Such structure, by the shorten length by pump cover, the volume of stationary ring, rotating ring increases, the volume of machine sealed cover reduces, the position transposing of stationary ring and rotating ring, rotating ring be positioned at the machine sealed cover towards bearing housing one side.During maintenance, take away support, just can observe directly rotating ring, the machine envelope is revealed very clear, is convenient to maintenance, and it is convenient to change, and can reduce maintenance man's workload, improves maintenance work efficiency, reduces maintenance cost.
Claims (2)
1. centrifugal pump, comprise the pump housing, the impeller assembly, pump cover, support, bearing housing, coupling and motor, the impeller assembly comprises axle, impeller, axle sleeve, rotating ring, stationary ring and machine sealed cover, impeller is positioned at the end of axle, described axle sleeve, rotating ring, stationary ring and machine sealed cover are positioned at the cavity of pump cover and support formation, described machine sealed cover is connected with pump cover, it is characterized in that: described stationary ring and rotating ring lay respectively at the both sides of machine sealed cover, between described machine sealed cover and pump cover, has the space of placing stationary ring, described rotating ring be positioned at the machine sealed cover towards bearing housing one side.
