Abstract
The utility model relates to a wear resistant ceramic pump sleeve, belonging to the field of a shaft sleeve for fixing a pump shaft in pump equipment. The wear resistant ceramic pump sleeve comprise a shaft sleeve body, wherein a cavity for installing the pump shaft is arranged in the middle part of the shaft sleeve body; the wear resistant ceramic pump sleeve is characterized in that a groove is arranged on the outer side wall of the shaft sleeve body, and a ceramic coating is arranged in the groove. A layer of ceramic is sprayed on the external surface of the pump sleeve, and then the pump sleeve is ground to a required size; the surface roughness of the pump sleeve reaches more than Rz0.8; the hardness of the pump sleeve reaches more than GRc70, therefore, the frictional force is reduced and the abrasion resistance is increased; and due to the setting of the ceramic coating, the seizing phenomenon does not occur between the pump sleeve and a packing; and the service life is more than 3 years.
Description
Technical field
The utility model provides a kind of wear-resistant ceramic pump block, belongs in the pump apparatus the fixedly axle sleeve field of pump shaft.
Background technique
Along with improving constantly of environmental requirement, people require also to improve constantly to the leakage of pump series products.According to related data, because the mechanical failure that causes of sealing problem reaches more than 40% of total failare rate, and cause the main cause of seal failure, then be due to the wearing and tearing and distortion of pump block.
Also there are many problems in packing filling in water pump uses: in the prior art, because packing directly contacts with axle sleeve, and relatively rotate during operation, certainly lead to certain heat and wearing and tearing, even cause the power consumption of motor to reach 5-10%, and a period of time do not start shooting, also can pump block take place and packing is killed phenomenon, cause to start difficulty and burn out motor.
The model utility content
According to above deficiency of the prior art, problem to be solved in the utility model is: the wear-resistant ceramic that a kind of frictional force is little, abrasion resistance is high pump block is provided.
The technological scheme that its technical problem that solves the utility model adopts is: the wear-resistant ceramic pump block, comprise sleeve body, and be provided with the cavity that pump shaft is installed at the middle part of sleeve body, it is characterized in that: the outer side wall of sleeve body is provided with groove, and ceramic coating is set in the groove.
Sleeve body outer surface at pump block is provided with one deck ceramic coating by spraying, is ground to require size, surface roughness to reach more than the Rz0.8 again; Hardness: more than the GRc70, during use, packing rubs mutually with ceramic coating, realizes reducing friction, and increases abrasion resistance, avoids killing phenomenon.
Wherein preferred version is:
Described thickness of ceramic coating is 0.15mm-0.2mm.Can be provided with as required, ceramic coated in groove then by the groove of machined into pump block outer surface, grinding then.
Described ceramic coating is concordant with the sleeve body outer side wall, and the distance at ceramic coating two ends and sleeve body two ends is 3-8mm, preferred 5mm.The non-ceramic coating of 3-8mm is reserved at two ends, can guarantee the soundness of ceramic coating, prolongs the spraying life-span.
The beneficial effect that the utility model wear-resistant ceramic pump block is had is: by the outer side wall at sleeve body groove is set, ceramic coating is set in the groove, by outer surface at pump block, spraying one deck pottery, be ground to again and require size, surface roughness to reach more than the Rz0.8; Hardness: more than the GRc70, reach and reduce friction, increase abrasion resistance; Because the setting of ceramic coating can not produce between pump block and packing and kill phenomenon, spray the life-span continuously to reach more than 3 years.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Wherein: 1, sleeve body 2, ceramic coating 3, cavity 4, chamfering.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As shown in Figure 1, be provided with the cavity 3 that pump shaft is installed at the middle part of sleeve body 1, sleeve body 1 is provided with chamfering 4, and the outer side wall of sleeve body 1 is provided with groove, and ceramic coating 2 is set in the groove.Ceramic coating 2 thickness are 0.15mm-0.2mm.Ceramic coating 2 is concordant with the sleeve body outer side wall, and the distance at ceramic coating 2 two ends and sleeve body 1 two ends is 3-8mm, preferred 5mm.
Add man-hour, can adopt following steps:
1, go out groove at pump block outer surface car earlier, the degree of depth is between 0.15-0.2mm, and not car of 5mm is respectively stayed at the two ends of sleeve body;
2, sandblast will be descended the tangent plane hacking;
3, spray ceramic coating, thickness is between the 0.3-0.4mm;
4, be ground to and require size.
The material of the sleeve body of mentioning in the utility model and use are common prior art, are set to common prior art in fact, and the technician is grasped by the industry.
Working principle and using process:
Sleeve body is arranged on the pump shaft, and outer surface ceramic coating place is provided with packing, and frictional force is little during use, and abrasion resistance avoids killing phenomenon.
Experiment effect: can obtain by repetition test:
1, the coating combination force is strong, difficult drop-off, and combination force is greater than 55KPa;
2, hardness height, combination force is strong, can reach 77-90HRc;
3, ceramic fusing point height is high temperature resistant, effectively resists the heat that produces between packing and the pump block;
4, ceramic coating is corrosion-resistant;
5, friction factor is little;
6, do not produce and kill phenomenon, do not start shooting for a long time, without Song's packing, prevent to burn motor etc. during beginning yet.
