Abstract

The utility model provides a novel fixed knot that can effectively improve water pump rotor holding capacity constructs, balance drum outside overlap in the water pump pivot, being located last -stage impeller, lock nut locking was fixed after balance drum's the outside looped through behind the balance drum clamping ring and balance drum. It has the high -pressure side axle sleeve still to overlap in the water pump pivot behind the balance drum outside the lock nut, the locking of double -deck lock nut was fixed after the outside of high -pressure side axle sleeve looped through behind the high -pressure side axle sleeve clamping ring and high -pressure side axle sleeve. This patent novel fixed knot that can effectively improve water pump rotor holding capacity constructs, through balance drum's setting, can guarantee the concentricity when the water pump pivot is rotatory, prevent that its deflection from leading to wearing and tearing to increase, simultaneously, balance drum also has radiating effect, can prevent that overheated leading to of water pump pivot from shutting down or burning out, through double -deck lock nut's behind high -pressure side axle sleeve and the high -pressure side axle sleeve setting, that can step forward compresses tightly each part, strengthens its fastness, effectively improves water pump rotor's holding capacity, extension water pump rotor's life.

Description

The Novel fixing structure of water pump rotor endurance can be effectively improved
Technical field
The utility model is related to a kind of fixed structure of water pump rotor, especially it is a kind of it is simple and reliable for structure, design it is ingenious, The Novel fixing structure of water pump rotor endurance can be effectively improved.
Background technology
Water pump is in all the time at a high speed and in the environment of high temperature operation, and its rotating shaft is with the lengthening of working time and the liter of temperature Height, each standing part has normal abrasion, and this concentricity for resulting in the rotation of rotating shaft produces skew, can further increase mill Damage, and the product of problems is not also solved on current market.
Utility model content
To solve the above problems, the utility model provide it is a kind of it is simple and reliable for structure, design it is ingenious, water can be effectively improved The Novel fixing structure of pump rotor endurance.
The Novel fixing structure of the effectively improved water pump rotor endurance of the utility model purpose is realized, including being enclosed within water Balancing drum in pump rotating shaft, on the outside of impeller, passes sequentially through pressure ring and balance after balancing drum on the outside of the balancing drum Locking nut is locked after drum.
High-pressure side axle sleeve is also cased with water pump shaft after the balancing drum on the outside of locking nut, the high-pressure side axle sleeve Outside passes sequentially through after the axle sleeve of high-pressure side that double-deck locking nut check is fixed after pressure ring and high-pressure side axle sleeve.
The Novel fixing structure of the effectively improved water pump rotor endurance described in this patent, by the setting of balancing drum, Concentricity when can ensure that water pump shaft rotates, prevents its deflection from causing abrasion to increase, meanwhile, balancing drum also has the effect for radiating Really, can prevent that water pump shaft is overheated to be caused to shut down or burn;The double-deck locking nut after high-pressure side axle sleeve and high-pressure side axle sleeve Setting, can further compress each part, strengthen its fastness, effectively improve the endurance of water pump rotor, extend water pump and turn The service life of son.
Description of the drawings
Fig. 1 is the structural representation of the Novel fixing structure for effectively improving water pump rotor endurance of the present utility model
Specific embodiment
As shown in figure 1, the Novel fixing structure for effectively improving water pump rotor endurance of the present utility model, including being enclosed within On water pump shaft 1, positioned at the balancing drum 3 in the outside of impeller 2, the outside of the balancing drum 3 passes sequentially through pressure ring 4 after balancing drum It is locked with locking nut after balancing drum 5.
High-pressure side axle sleeve 6, the high pressure side axle are also cased with after the balancing drum on the water pump shaft 1 in the outside of locking nut 5 The outside of set 6 passes sequentially through after the axle sleeve of high-pressure side that double-deck locking nut 8 is locked after pressure ring 7 and high-pressure side axle sleeve.
The Novel fixing structure of the effectively improved water pump rotor endurance described in this patent, by the setting of balancing drum 3, Concentricity when can ensure that water pump shaft 1 rotates, prevents its deflection from causing abrasion to increase, meanwhile, balancing drum 3 also has the effect for radiating Really, can prevent that water pump shaft 1 is overheated to be caused to shut down or burn;The double-deck locking screw after high-pressure side axle sleeve 6 and high-pressure side axle sleeve Female 8 setting, can further compress each part, strengthen its fastness, effectively improve the endurance of water pump rotor, extend water pump The service life of rotor.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality New scope is defined, under the premise of without departing from the utility model design spirit, this area ordinary skill technical staff couple Various modifications and improvement that technical solutions of the utility model are made, all should fall into the guarantor that claims of the present utility model determine In the range of shield.
