Embodiment
For making the purpose of this utility model, technological scheme and advantage clearer; the below will carry out clear, complete description to the technical solution of the utility model; based on the embodiment in the utility model; those of ordinary skills are resulting all other mode of executions under the prerequisite of not making creative work, all belong to the scope that the utility model is protected.
Embodiment one:
As shown in Figure 1, the cylinder sleeve that embodiment one of the present utility model provides comprises metal-coating 1, and the internal sleeve of metal-coating 1 is connected to wear-resistant liner cover 2.
It is socketed wear-resistant liner cover 2 by the inside at metal-coating 1, because wear-resistant liner overlaps 2 the good wear-resisting property that has, therefore can whole improve the wear-resisting property of cylinder sleeve, so that the longer service life of cylinder sleeve, and then reduced the replacing number of times of cylinder sleeve, guarantee the working efficiency of probing, reduced user cost.
In the present embodiment, owing to need set up wear-resistant liner cover 2 in the inside of metal-coating 1, and piston needs the reciprocates inside at wear-resistant liner cover 2, therefore the outer surface that needs to guarantee wear-resistant liner cover 2 will firmly be connected with the internal surface of metal-coating 1, also need simultaneously to guarantee to utilize easy for installation between metal-coating 1 and the wear-resistant liner cover 2 and produce; Therefore metal-coating 1 is connected 2 and can bondingly connects with wear-resistant liner, its outer surface by bonding assurance wear-resistant liner cover 2 will firmly be connected with the internal surface of metal-coating 1, simultaneously bonding also can so that easy for installation between metal-coating 1 and the wear-resistant liner cover 2 utilize and produce; What need assurance is, metal-coating 1 and wear-resistant liner are overlapped 2 bonding binders should adopt resistant to elevated temperatures binder, thereby guarantee the piston temperature that friction produces when the reciprocates inside of wear-resistant liner cover 2, can not cause the inefficacy of binder, and then prevent the generation of the situation that the cover 2 of wear-resistant liner in the reciprocating motion of the pistons and metal-coating 1 break away from.
In the present embodiment, but metal-coating 1 and also interference fit socket of wear-resistant liner cover 2, wherein preferred, can inlay wear-resistant liner cover 2 in the internal heat of metal-coating 1, because metal-coating 1 and wear-resistant liner cover 2 adopt interference fit, so that wear-resistant liner cover 2 and metal-coating 1 socket is more fastening, prevent the generation of the situation that wear-resistant liner cover 2 and metal-coating 1 break away from the reciprocating motion of the pistons.
In the present embodiment, because wear-resistant liner cover 2 is socketed in the metal-coating 1, therefore also can extend and form an inserted part 3 to the cavity direction of metal-coating 1 in an end of metal-coating 1, and an end of wear-resistant liner cover 2 is resisted against on the inserted part 3, utilize the 3 pairs of wear-resistant liner covers 2 in inserted part to play effect spacing, that stop, wear-resistant liner cover 2 is played better supporting effect, further prevent the generation of the situation that wear-resistant liner cover 2 and metal-coating 1 break away from the reciprocating motion of the pistons.
In the present embodiment, because the high-abrasive material cost is higher, for the effective manufacture cost of control wear-resistant liner cover 2, and then accomplish control to the cylinder sleeve holistic cost, improve the effect and cost rate of cylinder sleeve; Therefore the thickness range of wear-resistant liner cover 2 should be between 4～8mm, the thickness of further preferred wear-resistant liner cover 2 should be 5mm, thereby when guaranteeing that control wear-resistant liner cover 2 has good wear-resisting property, also can effectively reduce the manufacture cost of wear-resistant liner cover 2, and then accomplish the control to the cylinder sleeve holistic cost.
In the present embodiment, because the Environmental Conditions of cylinder sleeve is comparatively abominable, simultaneously because the to-and-fro motion meeting of piston causes certain mechanical shock to wear-resistant liner cover 2, so wear-resistant liner cover 2 also needs to possess certain anti-mechanical shock performance; So wear-resistant liner cover 2 can be in astable zirconium oxide disperse reinforced alumina ceramic neck bush, yttrium stable zirconium oxide reinforced alumina ceramic neck bush, the zirconium oxide matrix composite ceramics neck bush any, wherein zirconium oxide matrix composite ceramics neck bush main material is Y-TZP/Al
2O
3These three kinds of ceramic-lined covers are to be prepared from by granulation, cold isostatic compaction, repaired biscuit moulding, once sintered, fine finishing, have better Fracture Toughness and resistance to flexure, thereby further guaranteed the wear resistance of wear-resistant liner cover 2, and so that the mechanical shock resistance of wear-resistant liner cover 2 be improved, so that the longer service life of integral cylinder liner, and then reduced the replacing number of times of cylinder sleeve, improved the working efficiency of probing.
In the present embodiment, because metal sleeve itself has good mechanical shock resistance, so the main body of wear-resistant liner cover 2 also can select metal sleeve, and then the inner surface at metal sleeve is provided with ceramic coating, in order to improve the wear-resisting property of metal sleeve; Be that wear-resistant liner cover 2 comprises metal sleeve and ceramic coating, ceramic coating is arranged on the inner surface of metal sleeve; Thereby effectively guaranteed the wear resistance of wear-resistant liner cover 2, and so that the mechanical shock resistance of wear-resistant liner cover 2 is improved, so that the longer service life of integral cylinder liner, and then reduced the replacing number of times of cylinder sleeve, improved the working efficiency of probing.
Embodiment two:
Embodiment two of the present utility model provides a kind of slurry pump, comprises cylinder sleeve and piston, and cylinder sleeve is the cylinder sleeve described in above-described embodiment one, and cylinder sleeve cooperates with piston.Because cylinder sleeve is the main wear-out part of slurry pump, and above-mentioned cylinder sleeve has good wear-resisting property, therefore so that adopt the slurry pump of this cylinder sleeve to have longer working life.
It should be noted that at last: above mode of execution and embodiment only in order to the technical solution of the utility model to be described, are not intended to limit; Although with reference to aforementioned embodiments and embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technological scheme that aforementioned embodiments or embodiment put down in writing, and perhaps part technical characteristics wherein is equal to replacement; And these modifications or replacement do not make essence disengaging the utility model mode of execution of appropriate technical solution or the spirit and scope of embodiment's technological scheme.
