Abstract
The utility model provides a novel balance-adjustable spiral centrifugal impeller, and particularly relates to the technical field of mechanical devices. The balance-adjustable spiral centrifugal impeller comprises a spiral centrifugal impeller body (1) and a blade wheel (2), wherein the blade wheel (2) is spirally arranged on the outer side of the spiral centrifugal impeller body (1), and is characterized by further comprising a balance-adjusting block (3), and the balance-adjusting block (3) is arranged inside the spiral centrifugal impeller body (1). According to the novel balance-adjustable spiral centrifugal impeller, the balance-adjusting block is added on the opposite of a part prone to abrasion, when the impeller is imbalanced due to abrasion, the weight of the balance-adjusting block is reduced through the adoption of a method of material cutting to enable the impeller to reach balance again, thus vibration is eliminated, and the service life of the impeller and equipment is prolonged.
Description
Technical field:
The utility model relates to the mechanical device technical field, is specifically related to the adjustable screw centrifugal of a kind of novel balance.
Background technique:
Screw centrifugal is the core of helico-centrifugal pump inside, mainly plays the effect of transmission.But in use relative wear is very fast for the centrifugal part of screw centrifugal, can cause the impeller disequilibrium, causes vibration equipment, inefficacy, and working life is short, even can cause danger, has potential safety hazard.
Add balance adjustment piece on the opposite of part easy to wear, when impeller produced imbalance because of wearing and tearing, the weight that adopts the method for removing material to deduct balance adjustment piece made impeller reach balance again, to eliminate the working life of vibration prolongation impeller and equipment.
The model utility content:
The purpose of this utility model provides the adjustable screw centrifugal of a kind of novel balance, it adds balance adjustment piece on the opposite of part easy to wear, when impeller is uneven because of wearing and tearing produce, the weight that adopts the method for excising material to deduct balance adjustment piece makes impeller reach balance again, vibrates the working life that prolongs impeller and equipment to eliminate.
In order to solve the existing problem of background technique, the utility model is by the following technical solutions: it comprises screw centrifugal body 1, impeller 2, described impeller 2 spirals are arranged on the outside of screw centrifugal body 1, it is characterized in that it also comprises balance and adjusts piece 3, described balance is adjusted the inside that piece 3 is arranged on screw centrifugal body 1.
The position that described balance adjustment fast 3 is provided with is corresponding with impeller easy to wear 2.
The utility model working principle: when imbalance appears in screw centrifugal, we reduce inner corresponding with it the balance adjustment piece of device according to the impeller location grinding of wearing and tearing, make it reach again balance and can continue to use, repeatable operation according to this increases its working life.
The utlity model has following beneficial effect: the weight that it adopts the method for excising material to deduct balance adjustment piece makes impeller reach balance again, vibrates the working life that prolongs impeller and equipment to eliminate.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the sectional drawing of A-A among the utility model Fig. 1;
Fig. 3 be among the utility model Fig. 1 X to schematic representation.
Embodiment:
Referring to Fig. 1-3, this embodiment is by the following technical solutions: it comprises screw centrifugal body 1, impeller 2, described impeller 2 spirals are arranged on the outside of screw centrifugal body 1, it is characterized in that it also comprises balance and adjusts piece 3, described balance is adjusted the inside that piece 3 is arranged on screw centrifugal body 1.
The position that described balance adjustment fast 3 is provided with is corresponding with impeller easy to wear 2.
This embodiment working principle: when imbalance appears in screw centrifugal, we reduce inner corresponding with it the balance adjustment piece of device according to the impeller location grinding of wearing and tearing, make it reach again balance and can continue to use, repeatable operation according to this increases its working life.
This embodiment has following beneficial effect: the weight that it adopts the method for excising material to deduct balance adjustment piece makes impeller reach balance again, vibrates the working life that prolongs impeller and equipment to eliminate.
