Abstract
The utility model relates to a novel adjusting device for an auxiliary impeller of a self-control self-sucking pump with no seal. The device comprises the auxiliary impeller, an auxiliary blade, a shaft and a shaft sleeve. The utility model is characterized in that the shaft sleeve is fixedly connected on the shaft through a positioning bolt, the auxiliary impeller is positioned on the shaft through the shaft sleeve, a radial adjusting groove is arranged on the auxiliary impeller and the auxiliary blade is arranged in the adjusting groove and is connected with the auxiliary impeller. The utility model has the advantages that the axial clearance can be adjusted and the blade width can be also adjusted; and the method of changing part dimension through machining is not adopted and the goal of adjustment is reached through the different combinations of the positions of a plurality of parts.
Description
Technical field
It is a kind of nothing sealing automatic control self-priming pump sub-propeller that the utility model relates to, particularly a kind of novel regulating device mode that is applied to not have sealing automatic control self-priming pump sub-propeller.
Background technique
The sealing means of non-sealing self-sucking pump is the dynamic seal mode that has adopted sub-propeller, the seal action of sub-propeller mainly is to produce the pressure with the main impeller pressure in contrast by sub-propeller, reach the effect of the pressure of offsetting the main impeller generation, thereby liquid is sealed up.Because the effect of sub-propeller is sealing, so its desired impact is not reveal, the gap of sub-propeller and back shroud is just extremely important so, can not be big, can not be too little, width of blade on the sub-propeller can not be too wide, too wide consumed power is serious, cause inefficiency, can not be too narrow, the sealing of too narrow fearness is incessantly done by theoretical value when design usually, all is after the test by reality for the width of the gap of sub-propeller and bonnet and sub-propeller upper blade in the process of actual production, width by plus-minus pad and smear metal sub-propeller blade on axle comes control gap and power, sometimes the sub-propeller of a pump need be adjusted and go up lathe cutting three or four times, and is very loaded down with trivial details, is unfavorable for the unification of sub-propeller mould and the adjustment of actual conditions.Just want to adopt now a kind of new adjustment mode, can the adjusting play, can adjust the width of blade of sub-propeller again, but also want mode simple relatively.
Summary of the invention
The purpose of this utility model is to solve that the gap of sub-propeller and back shroud is that lathe cutting reaches on the existing needs by controlling at the width of plus-minus pad and smear metal sub-propeller blade on the axle in the prior art, the unified problem that is unfavorable for the sub-propeller mould provides a kind of novel regulating device that does not have sealing automatic control self-priming pump sub-propeller.A kind of novel regulating device that does not have sealing automatic control self-priming pump sub-propeller of the utility model design, comprise sub-propeller, back blades, axle, axle sleeve is characterized in that: axle sleeve is fixedly connected on the axle by holding down bolt, and sub-propeller is positioned on the axle by axle sleeve, offer adjustment groove radially on the sub-propeller, back blades is positioned at the adjustment groove and is connected with sub-propeller.The utility model has the advantages that and to adjust axial clearance, also want simultaneously to adjust width of blade; Do not adopt the mode of machining change accessory size, only reach the purpose of adjustment by the position various combination of several parts.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is a sub-propeller structural representation of the present utility model.
Accompanying drawing 3 is the AA generalized section of Fig. 2 of the present utility model.
Below in conjunction with accompanying drawing and example the utility model is elaborated.
Embodiment
The purpose of this utility model is the problem that solves the adjustment mode inconvenience of non-sealing self-sucking pump sub-propeller.At first, change the shaft shoulder location of sub-propeller 1 into axle sleeve 4 location, axle sleeve 4 can axially be adjusted on axle 3, the back blades 2 of sub-propeller 1 can be dismantled separately, and can do radially dismounting, play the effect of adjusting axial clearance and back blades 2 width, when needs back blades 2 width widen or axial clearance diminish, back blades 2 can be extracted out along adjusting groove 6, conversion back blades 2 is in the position of adjusting groove 6, back blades 2 just can play the effect that broadens so, when the adjustment of the adjustment of back blades 2 and axle sleeve 4 is combined, just can obtain gap and back blades 2 width wanted easily.
