Abstract
The utility model relates to a multi-stage centrifugal pump intellignecy suspension balancing disc, which is provide with 10 to 22 grooves with the depth between 5Mum to 100Mum on working surface of the balancing disc. Linear type of the groove can be the spiral line, arc and beeline. When the centrifugal pump works normally, opening groove not affect the normal function of the balancing disc. If the balancing disc looses balancing and then approximates to the balancing seat, the balancing disc makes the balancing force produced by the balancing plate which is opposite with the pump shaft force is greatly increased. The nearer for the working surface of the balancing disc and the working surface of the balancing seat, the bigger the starting force produced is, thereby preventing the contact for the balancing disc and the balancing seat working surface, which can obviously increase service life of the balancing disc, and also can reduce damaging possibility for the related components inside the pump as well as the maintenance workload.
Description
The utility model relates to the axial thrust balancing devices of multistage centrifugal pump Balance disc, particularly pump.
In normal multistage centrifugal pump, between Balance disc and the balance ring seat certain clearance is arranged.When pump work, Balance disc does not contact with balance seat working surface, dry friction can not take place in the two, but because improper, ambient condition of assembling or technological fluctuation, can make Balance disc unbalance and abut on the balance seat, cause the heavy wear of Balance disc and balance seat, also can cause simultaneously the damage of other parts in the pump, make maintenance load increase the centrifugal pump lost of life, the continuity that influence is produced causes enormous economic loss.
The purpose of this utility model is the floated Balance disc of a kind of novel centrifugal pump of exploitation intelligence, prevents from that Balance disc from abutting on the balance seat to cause wearing and tearing, prolongs Balance disc and pump working life.
The purpose of this utility model is achieved in that opens the groove of 10～22 degree of depth at 5 μ m～100 μ m on the Balance disc working surface, the groove electrical path length is 30%～80% of a face width, and the line style of groove can be helix, circular arc and straight line.The peripheral width of groove is 1～2.2 with the ratio of boss circumferential width; Groove arranges evenly that with respect to the Balance disc central axis groove can be partial to the working surface outside, also can be partial to the working surface inboard; The bending direction of time slot is identical with turning to of pump shaft outside being partial to, when the switched in opposite of the bending direction of being partial to inboard time slot and pump shaft.
The utility model is opened some grooves on the working surface of conventional Balance disc, simple in structure.When the centrifugal pump proper functioning, the balanced action of Balance disc is constant substantially; It is close if Balance disc is unbalance to the balance seat, then Balance disc is because the double action of power wedge and liquid pumping, the equilibrant opposite with the pump axial force that Balance disc is produced sharply increases, Balance disc working surface and balance seat working surface are at a distance of near more, the opening force that produces is big more, prevents that Balance disc from contacting with balance seat working surface and the purpose that takes place to dry grind thereby reach.The Balance disc life-span can be obviously increased, and possibility and maintenance load that other associated components damages can be reduced.
Fig. 1 is the floated Balance disc generalized section of centrifugal pump intelligence.
Fig. 2 is the inboard fluting of the floated Balance disc working surface of a centrifugal pump intelligence schematic representation.
Fig. 3 is the floated Balance disc working surface of a centrifugal pump intelligence outside fluting schematic representation.
Describe the concrete structure of the floated Balance disc of centrifugal pump intelligence that proposes according to the utility model in detail below in conjunction with drawings and Examples.
Be illustrated in figure 2 as one of embodiment of the present utility model, the 1st, Balance disc, the 2nd, weir, the 3rd, groove, the 4th, boss.Open 15 grooves in Balance disc working surface inboard, groove is circumferentially uniform, bending direction and pump shaft switched in opposite, and groove depth 50 μ m, interior circular groove is wide 18.6 millimeters, and the cylindrical width of groove is 10.0 millimeters, and the true dip direction of every a groove is for becoming 76 ° of angles with corresponding radius.Figure 3 shows that another embodiment of the present utility model, open 20 grooves in the Balance disc working surface outside, groove is circumferentially uniform, the bending direction of groove turns to identical with pump shaft, groove depth 50 μ m, 20.3 millimeters of cylindrical groove widths, the interior round width of groove is 17.3 millimeters, the true dip direction of every a groove is for becoming 60 ° of angles with corresponding radius.Produce equilibrant and do not slot basic identically, do not influence the installation dimension of pump.Because some accidentalia, Balance disc is when the balance seat is close, and its opening force sharply increases automatically, prevent that Balance disc is affixed on the balance seat, can prevent the damage of other parts in Equilibrator and the pump, prolong the working life of pump, the assurance production safety is moved continuously, has huge economic benefit.
Claims (3)
1. the floated Balance disc of multistage centrifugal pump intelligence, it is characterized in that on the Balance disc working surface, opening the groove of 10～22 degree of depth at 5 μ m～100 μ m, the line style of groove can be helix, circular arc and straight line, and the peripheral width of groove is 1～2.2 with the ratio of boss circumferential width.
2. multistage centrifugal pump Balance disc according to claim 1 is characterized in that: groove arranges evenly that with respect to the Balance disc central axis groove can be partial to the working surface outside, also can be partial to the working surface inboard; When the bending direction of biased outward time slot identical with turning to of pump shaft, when the deflection bending direction of inboard time slot and the switched in opposite of pump shaft.
3. according to right 1 described multistage centrifugal pump Balance disc, it is characterized in that the groove electrical path length is 30%～80% of a face width.
