Abstract
An anti-rust anti-wear backing strip for pumps is made from anti-rust anti-wear material, the anti-rust anti-wear backing strip (1) is annular and is fixed to the position of the rotation surface of an impeller (4) facing a pump body (2) and a pump cover (3) by screw joint or rivet joint, and the existing running clearance is kept. The anti-rust anti-wear backing strip (1) can be applied in impeller pumps made from cast iron, cast steel and non-metallic material. The utility model is simple in structure, low in costs and convenient to assemble, maintain and repair.
Description
Technical field
The utility model relates to a kind of liner that guarantees the safe and reliable running of pump.
Background technique
Industrial pump on the current social, what commonly use most is impeller pump, its working principle is the potential energy that rotation function is converted to liquid by the high speed rotating of impeller, in order to realize high efficiency transformation of energy, for the pump of high-lift small flow structurally just the movement clearance between pump case and the impeller need be provided with very little, such structural type has brought unfavorable factor for the use of wing pump, the one, the little pump housing in gap easily is worn, finally cause the gap to become big, lift of pump descends, the 2nd, the pump housing mostly is cast iron greatly or cast steel material is made, especially stock or downtime get rusty under air effect very soon, corrosion and destruction movement clearance and stopped up the gap, even the pump housing with impeller because corrosion layer makes the two become the stall burnout failure that one very easily causes motor, so the waste that causes is surprising.
For a long time, people explore constantly and solve antirust and wear-resisting problem, for example with pump housing Cuprum alloy, stainless steel waits to be made, but involve great expense, the employing engineering plastics are also arranged, industrial ceramics, graphite waits makes the pump housing, but all because of its heatproof, wear-resisting and shock resistance difference are difficult to promote, yet there are no so far and effectively solve antirust wear-resisting method, especially the structural modification to maturation is little, the technological scheme that cost is low does not also occur, and this just demands us urgently and goes to solve.
Summary of the invention
According to background technique, the liner that the material that the purpose of this utility model is to provide a kind of usefulness to have antirust wear-resisting property is made is fixed on the pump housing, to reach the running of the safe and reliable manuscript paper amount of pump, but also it is few to reach materials, install simple and easy, very little to original structure secondary process amount, technical purpose with low cost, the existing pump housing made from engineering plastics or other nonmetallic material of repacking that it also can be very easily simultaneously, also available this liner is safeguarded pump housing place under repair, prolongs the working life of its pump.
In order to achieve the above object, the utility model is achieved through the following technical solutions: a kind of usefulness has the antirust unworn liner (1) that the material of antirust wear-resisting property is made, its structure shape is for having certain thickness annular, be fixed in the pump housing (2) and pump cover (3) regards on the position of impeller (4) surface of revolution by screw (11), and keep the movement clearance between original impeller (4) and the pump housing (2) and the pump cover (3).
By above-mentioned technological scheme, the utlity model has following advantage and effect:
1, to be used in cast iron and cast steel be on the pump of material to the utility model, can reach the whole using effect of nonferrous materials pump that is.
2, on the pump that the utility model can be used for making with nonmetallic material, can improve the wear resistance of the pump housing (2) and pump cover (3), prolong the working life of pump.
3, the utility model also can be used for repairing the work of safeguarding the pump housing, be used to repair the pump housing and the pump cover that have been worn or have corroded, if it is simpler when the pump that has used the utility model liner is repaired, need only change a lower liner again gets final product, it is simple and easy to repair maintenance, with low cost, water pump can use as new pump again, and reduction effect is considerable.

Among the figure: the antirust unworn liner of 1-, 11-screw, the 2-pump housing, 3-pump cover, 4-impeller, 5-binder
Embodiment
Shown in Figure 1A and Figure 1B, be first embodiment of the present utility model, the antirust unworn liner made from material 1 with antirust wear-resisting property, its structure shape is for having certain thickness annular, be fixed in the pump housing 2 and pump cover 3 regards on the position of impeller 4 surface of revolution by screw 11, and keep the movement clearance between original impeller 4 and the pump housing 2 and the pump cover 3.
As can be known, the pump form of impeller type is a lot, have can be in the pump housing side dress liner, what have can be in both sides, in the pump that can adorn liner, the most representative is peripheral pump.
At first, select the material of liner as required, for example optional Cuprum alloy, stainless steel and other nonmetallic material, the thickness of its liner should be decided on the intensity of material and the parameter request of pump, is fixed on the pump housing 2 and the pump cover 3 with screw 11 or rivet or bonding way afterwards.
From figure also as can be known, antirust unworn liner 1 its shape is mainly annular, and the also visual concrete pump housing 2 and the structure of pump cover 3 need have local the change slightly.
Claims (3)
1, the antirust unworn liner of a kind of pump, the antirust unworn liner made from material (1) with antirust wear-resisting property, it is characterized in that: structure shape is for having certain thickness annular, be fixed in the pump housing (2) and pump cover (3) regards on the position of impeller (4) surface of revolution by screw (11), and keep the movement clearance between original impeller (4) and the pump housing (2) and the pump cover (3).
2, the antirust unworn liner of pump according to claim 1 is characterized in that: antirust unworn liner (1) can select for use metal or nonmetallic material to make.
3, the antirust unworn liner of pump according to claim 1 is characterized in that: antirust unworn liner (1) also can adopt riveted joint, bonding way with the means of fixation of the pump housing (2) and pump cover (3).
