Abstract
The utility model relates to the field of mechanical sealing device, in particular to a sewage pump sealing device. The sewage pump sealing device comprises a pump shaft, a static ring seat, a dynamic ring seat, a positioning seat and a spring seat arranged on the pump shaft in a sleeved mode. The dynamic ring seat is arranged below the spring seat, the static ring seat is arranged below the dynamic ring seat, and the positioning seat is arranged on the outer portion of the pump shaft in a sleeved mode and is placed below the dynamic ring seat. The spring seat is fixedly connected with the pump shaft through a fastening screw, the positioning seat is in sealing connection with the dynamic ring seat through a static ring seat sealing ring, the spring seat is in sealing connection with the pump shaft through a pump shaft sealing ring, and the spring seat is in sealing connection with the dynamic ring seat through a dynamic ring seat sealing ring. The sewage pump sealing device can reduce abrasion of the contact end faces of a dynamic ring, a static ring, the pump shaft and the like, improve the sealing performance of the sealing device, and prolong the service life of the sealing device.
Description
Technical field
The utility model relates to mechanical seal device field, relates in particular to a kind of sealing device for sewage pump.
Background technique
At present, the seal form that sewage pump product is conventional mainly contains two kinds: packing seal and mechanical seal.Wherein, there is following defect in packing seal: the impurity that 1, sealing medium contains has a strong impact on sealability; 2, unstable working condition needs the frequent filler of adjusting and change; 3, serious wear causes energy input large.And mechanical seal has the advantages such as friction power loss is little, the life-span long and do not reveal, it is widely used in water pump.But, in use, between the parts such as the rotating ring of mechanical seal, stationary ring and pump shaft, produce frictional force, easily cause contact jaw surface wear, reduce sealability, shorten the working life of mechanical seal device.
Summary of the invention
The purpose of this utility model is to provide a kind of sealing device for sewage pump, can reduce the wearing and tearing that contact end face between the parts such as rotating ring, stationary ring and pump shaft, improves sealability, extends the working life of seal arrangement.
For reaching this object, the utility model by the following technical solutions:
The utility model provides a kind of sealing device for sewage pump, comprise pump shaft, stationary seat, rotating seat, positioning seat and be sheathed on the spring seat on described pump shaft, described rotating seat is located at the below of described spring seat, described stationary seat is located at the below of described rotating seat, described positioning seat is sheathed on the outside of described pump shaft, and be positioned at the below of described rotating seat, described spring seat is fixedly connected with described pump shaft by fastening screw trip bolt, and described positioning seat and described stationary seat are tightly connected by stationary seat seal ring;
Described spring seat and described pump shaft are tightly connected by shaft seal circle;
Described spring seat and described rotating seat are tightly connected by rotating seat seal ring.
As preferred version of the present utility model, the inside of described spring seat has spring groove, in described spring groove, spring is installed.
As preferred version of the present utility model, between described spring seat and the top of described rotating seat, there is throw-out collar.
As preferred version of the present utility model, the top of described positioning seat is provided with sealing gland, and described positioning seat is fixedly connected with described sealing gland by fixing bolt.
As preferred version of the present utility model, the material of described rotating seat seal ring, described shaft seal circle and described stationary seat seal ring is nitrile butadiene rubber or teflon.
The beneficial effects of the utility model are:
The sealing device for sewage pump that the utility model provides, it comprises pump shaft, stationary seat, rotating seat, positioning seat and spring seat, positioning seat and stationary seat are tightly connected by stationary seat seal ring, spring seat and pump shaft are tightly connected by shaft seal circle, spring seat and rotating seat are tightly connected by rotating seat seal ring, arranging of said structure reduced the wearing and tearing that contact end face between the parts such as rotating ring, stationary ring and pump shaft, improved the sealability of seal arrangement, extended the working life of seal arrangement.
Accompanying drawing explanation
Fig. 1 is the structural representation of the sealing device for sewage pump that provides of the utility model mode of execution.
Wherein:
1, pump shaft; 2, stationary seat; 3, rotating seat; 4, positioning seat; 5, spring seat; 6, Compress Spring; 7, rotating seat seal ring; 8, throw-out collar; 9, shaft seal circle; 10, sealing gland; 11, fastening screw trip bolt; 12, fixing bolt; 13, stationary seat seal ring.
Embodiment
Below in conjunction with accompanying drawing and by embodiment, further illustrate the technical solution of the utility model.
As shown in Figure 1, a kind of sealing device for sewage pump that present embodiment provides, comprises the parts such as pump shaft 1, stationary seat 2, rotating seat 3, spring seat 5 and positioning seat 4.Wherein, the top of positioning seat 4 is provided with sealing gland 10, and positioning seat 4 is fixedly connected with sealing gland 10 by fixing bolt 12, and here, positioning seat 4 had both played the effect of location pump shaft 1, can play seal action to pump shaft 1 again.
In addition,, in order to improve sealability, spring seat 5 is tightly connected by rotating seat seal ring 7 with rotating seat 3.When pump shaft 1 rotation, rotating ring produces relative rotation with stationary ring, on the surface of contact of rotating ring and stationary ring, can produce frictional force, causes certain wearing and tearing, adopts rotating seat seal ring 7 for compensating this wearing and tearing, has guaranteed the validity of seal arrangement.
The below of rotating seat 3 is provided with stationary seat 2, positioning seat 4 is sheathed on the outside of pump shaft 1, and be positioned at the below of rotating seat 3, in order further to improve the sealing reliability of this device, positioning seat 4 is tightly connected by stationary seat seal ring 13 with stationary seat 2, and spring seat 5 is tightly connected by shaft seal circle 9 with pump shaft 1.Rotating seat seal ring 7, shaft seal circle 9 and stationary seat seal ring 13 threes are O RunddichtringO, and their material is nitrile butadiene rubber or teflon, so can effectively strengthen the wear resistance of each seal ring, compensate the wearing and tearing that contact end face between each parts, extended the working life of sealing device.
Above combination embodiment has been described know-why of the present utility model.These are described is in order to explain principle of the present utility model, and can not be interpreted as by any way the restriction to the utility model protection domain.Explanation based on herein, those skilled in the art does not need to pay performing creative labour can associate other embodiment of the present utility model, and these modes all will fall in protection domain of the present utility model.
