Abstract
The invention discloses a submersible-sewage-pump impeller balancing tool. A submersible sewage pump is a sewage discharging device wide in purpose, convenient to install and move, efficient, resistant to winding, free of blocking, capable of achieving automatic coupling, multiple in protection mode and high in reliability, saves energy and has the unique impeller single/double-channel mode. An impeller is uneven in mass distribution due to accumulation of uneven materials, workblank defects, machining errors, assembling errors and the like, an unsymmetrical geometrical shape in design and the like, and certain eccentricity is generated. When the impeller rotates, unbalanced centrifugal inertia force is generated, and therefore vibration and noise are generated by the pump. The submersible-sewage-pump impeller balancing tool comprises a joint (1). The joint (1) is connected with a full-height half key (2), the full-height half key (2) is connected with an auxiliary rotary shaft (6), the impeller (5) is installed on the auxiliary rotary shaft (6) and connected with a baffle (4), and the baffle (4) is connected with a nut (3). The submersible-sewage-pump impeller balancing tool is used for the impeller of the submersible sewage pump.
Description
technical field:
the present invention relates to a kind of submersible sewage pump impeller balance tooling.
background technique:
proof submersible sand discharging pump is a kind of broad-spectrum effluent discharge equipment, and conveniently moving, energy-efficient, antiwind, high without obstruction, automatic coupling, kinds of protect, reliability is installed.There is unique impeller list (two) runner form.Impeller because material is inhomogeneous, the accumulation of blank defect, machining error, assembly error etc., and the asymmetry geometrical shape existing during design etc., makes its non-uniform mass, forms certain bias.When vane rotary, produce unbalanced centrifugal inertia force, thereby make pump produce vibration and noise.
summary of the invention:
the object of this invention is to provide a kind of submersible sewage pump impeller balance tooling.
above-mentioned object realizes by following technological scheme:
a submersible sewage pump impeller balance tooling, its composition comprises: joint, described joint is connected with overall height half bond, described overall height half bond is connected with auxiliary rotating shaft, in described auxiliary rotating shaft, impeller is installed, described impeller is connected with baffle plate, and described baffle plate is connected with nut.
beneficial effect:
during vane rotary, have wind pressure load, the air entrapment that excessive blast produces, will increase the noise of sensor signal, and watt meter luminous point rocks, and affects balance quality and efficiency.The present invention has designed a baffle plate in auxiliary rotating shaft place of impeller, with nut, carries on the back, and seals intake grill.The quality of fit of auxiliary rotating shaft and impeller is selected H7/g6 level, fixes, in order to avoid impeller axial float with shoulder.When vane rotary, the present invention has reduced the unbalanced centrifugal inertia force of generation, thereby makes pump produce vibration and noise, reduces the vibration of pump, improves proof submersible sand discharging pump reliability of operation.
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present invention.
embodiment:
embodiment 1:
a submersible sewage pump impeller balance tooling, its composition comprises: joint 1, described joint is connected with overall height half bond 2, described overall height half bond is connected with auxiliary rotating shaft 6, in described auxiliary rotating shaft, impeller 5 is installed, described impeller is connected with baffle plate 4, and described baffle plate is connected with nut 3.Overall height half bond is balance key.
embodiment 2:
described submersible sewage pump impeller balance tooling, its technique that obtains balance tooling is as follows:
(1) pack the good auxiliary rotating shaft of balance into impeller, joint and universal shaft coupling headstock dish are connected and are fastening, and the stroke regulating screw of universal shaft coupling is tightened up.In order to avoid workpiece axial float.
(2), according to the loading form of workpiece, select working state switch.
(3) measure and input a size (left correcting plane is to the distance between left supporting surface), b size (distance between left and right correcting plane), c size (right correcting plane is to the distance between right supporting surface).Measure and input r, size (radius at left correcting plane correction position place), r' size (radius at right correcting plane correction position place).Weight phaseswitch is placed in to " gently " position.
(4) before impeller calibration balance, must be in all switching position and knob position adjusted good in the situation that, first adjust the luminous point zero-bit of electrical measurement case, now, by sensitivity switch ground connection (being that one, its button is not pressed yet), press again " startup " button, make workpiece rotation, by two adjusting screw in left and right, bottle opener turn " luminous point vector watt meter " upper end, make luminous point be positioned at the center of circle of dial, when conversion rotating speed or change loading form, need reexamine luminous point zero-bit.
(5) drive to drag vane rotary, write down phase place and lattice number that the luminous point of left and right two watt meters moves, the reduction value of balance be the product of the represented sensitivity of reading (lattice number) on watt dial plate and sensitivity switch button.Corresponding to phase angle of unbalance, on impeller front and rear cover plate, mark.By impeller front and rear cover plate mark place's milling duplicate removal.
(6) will assist rotating shaft and impeller reversion 180.Connect, re-start balance correction, record respectively phase angle of unbalance and the grams of two rectifying planes, in impeller front and rear cover plate mark place's milling duplicate removal.
(7) after duplicate removal, by the retrial on balancing machine of tested impeller, until the amount of unbalance of impeller remnants has been less than the check value of allowable amount of unbalance.Illustrate that impeller has reached balance requirement.
embodiment 3:
described submersible sewage pump impeller balance tooling, impeller dynamic balance checking is to carry out on YYW-300A hard bearing balan, while using YYW-300A hard bearing balan dynamic balance checking, needs a high-precision parts joint to be connected with universal shaft coupling.Impeller is without axle journal part, needs an auxiliary rotating shaft impeller rotation.For guaranteeing balance quality, joint and universal shaft coupling activity connect between fork, between joint and auxiliary rotating shaft, and matching gap should be the smaller the better, but will guarantee easy to assembly simultaneously.Therefore, joint and universal joint are selected H6/h5 level quality of fit, and H7/g6 level quality of fit is chosen in joint and auxiliary rotating shaft.Because axial float will strengthen matching gap, therefore, at joint cylindrical, bore two screws in 180 ~ position each other, two Cock screws that the quality of screwing on equates, hold out against the auxiliary rotating shaft of impeller, in order to avoid axial float.Joint design is two keyway arrangements, and workpiece can connect by Rotate 180 ° (joint is motionless), joint and auxiliary rotating shaft balance key connecting.
from the present situation of current submerged pump industry, the vibration of pump and noise problem remain the general character quality problems of industry.The vibration of pump causes by many factors, and its rotor dynamic unbalance and impeller dynamic unbalance are two key factors.Each enterprise has accumulated rich experience to rotor examination dynamic balancing, has found effective control measure, but impeller examination dynamic balancing is not had to enough attention, and the quality of pump is affected.Enterprise in process of production, progressively inquires into and solves dynamic balance of impeller problem, and the general character quality problems of this industry are resolved, and quality of product will inevitably improve.
