Abstract
The utility model discloses a ceramic cylinder liner, relating to the improvement on the structure of the cylinder liner at a critical component of a petroleum drilling pump. The ceramic cylinder liner comprises a metal outer liner 1 and is characterized in that the metal outer liner is internally provided with a zirconium oxide ceramic inner liner 2 which is hot embedded with the metal outer liner into one integrated body. The advantages are as follows: the metal outer liner consisting the ceramic cylinder liner has enough rigidity to protect the ceramic inner liner; the ceramic cylinder liner is used for substituting for the original double metal cylinder liners to assemble in the petroleum drilling pump; as the ceramic inner liner of the ceramic cylinder liner has unique wear resistance and high hardness, the service life is prolonged and can achieve more than four thousand hours, so that the number of times for replacing the cylinder liner is reduced; manpower, material resources and financial resources are saved; and the working efficiency of a drilling machine is improved. The ceramic cylinder liner can be broadly used for the petroleum drilling pumps.
Description
(1) technical field
The utility model relates to a kind of improvement of critical component cylinder sleeve structure of oil drilling pump.Be a kind of ceramic cylinder jacket specifically.
(2) background technique
Cylinder sleeve is the critical component of oil drilling pump, directly influences the working efficiency of rig its working life.What routine was used in the drillng operation at present is bi-metal liner, overcoat adopts No. 45 steel spun castings to form, and the spun casting of interior cover Cai Yong Gao Chrome cast iron forms, and then by the heat treatment hot quenching, interior cover hardness can reach HRC60-63, serviceable bife 600-800 hour.Because working life is shorter, cylinder sleeve of every replacing all can spend very long drilling time and human and material resources, cost, serious reduction the working efficiency of rig.
(3) summary of the invention
The utility model purpose is to overcome the shortcoming in the above-mentioned technology, proposes a kind of ceramic cylinder jacket, replaces original bi-metal liner to be assemblied in the oil drilling pump, to prolong its working life, reduce the number of times of changing cylinder sleeve, save human and material resources, financial resources, to improve the working efficiency of rig.
The utility model purpose is realized by following technological scheme: this ceramic cylinder jacket, metal-coating 1 is arranged, and it is characterized in that in metal-coating, having in the zirconia ceramics that becomes one with the hot insert of metal-coating and overlap 2.
Cover 2 is to adopt the zirconia ceramics powder through isostatic compaction in the pottery, and high-temperature firing forms.This interior cover 2 of the pottery that forms of firing has very high wear resistance and enough intensity, after special processes, becomes one with metal-coating 1 hot insert.Thereby form metal-coating 1 cover 2 in enough rigid protective potteries is arranged, and cover 2 there are unique wear resistance and high hardness, high strength in the pottery.
The utility model advantage is: the metal-coating of forming ceramic cylinder jacket has cover in enough rigid protective potteries; replace original bi-metal liner to be assemblied in the oil drilling pump with ceramic cylinder jacket; owing to be with unique wear resistance and high hardness in the pottery of ceramic cylinder jacket; prolonged working life; reach working life more than 4000 hours; reduce the number of times of changing cylinder sleeve, saved human and material resources, financial resources, improved the working efficiency of rig.
(4) description of drawings
Fig. 1 is a kind of ceramic cylinder jacket structural representation.
(5) embodiment
Embodiment of accompanying drawings.Fig. 1 represents a kind of structure of ceramic cylinder jacket.This ceramic cylinder jacket has metal-coating 1, has in the zirconia ceramics that becomes one with the hot insert of metal-coating to overlap 2 in metal-coating 1.Cover 2 is to adopt the zirconia ceramics powder through isostatic compaction in the pottery, and high-temperature firing forms.This interior cover 2 of the pottery that forms of firing has very high wear resistance and enough intensity.Reach more than 4000 hours the working life of ceramic cylinder jacket, reduced the number of times of changing cylinder sleeve, saved human and material resources, financial resources.
Claims (1)
1. a ceramic cylinder jacket has metal-coating (1), it is characterized in that having in metal-coating cover (2) in the zirconia ceramics that becomes one with the hot insert of metal-coating.
