Abstract
The utility model discloses a novel cooling drilling pump cylinder sleeve piston connecting rod, which comprises a piston connecting rod body, wherein the lower end of the piston connecting rod body is provided with a flange, the lower end of the flange is provided with a piston connecting shaft, a water conveying passage is arranged in the piston connecting rod body, and water spraying holes are formed in the vertical wall of the flange and are uniformly distributed on the vertical wall of the flange. The novel cooling drilling pump cylinder sleeve piston connecting rod replaces an external hanging water spraying accessory device, and the problem of poor cooling effect of spraying water is solved, so all-around cooling of a drilling pump cylinder sleeve is realized, further, the cooling effect is more reliable, the effect is better, the production cost is reduced, the work load of workers is reduced, the production efficiency is improved, and the novel cooling drilling pump cylinder sleeve piston connecting rod is suitable for being widely popularized.
Description
Technical field
The utility model relates to a kind of piston rod, especially relates to a kind of novel cooling drilling pump cylinder jacket piston connecting rod.
Background technique
Along with petroleum and natural gas exploitation is to drilling safety construction requirement, also drilling pump ride quality and safety are proposed to more and more higher requirement, require power of slush pump increasing, also require the working life of drilling pump easily damaged parts more and more longer.One of easily damaged parts of drilling pump is cylinder sleeve piston.Extend the life-span of cylinder sleeve piston, under the material of cylinder sleeve piston itself and the certain condition of structure, as service condition aspect, cooling problem that must extraordinary solution cylinder sleeve piston, the effect of piston rod just conduct connects power end of drilling pump and piston, then there is no other functions.Existing for solving the cooling problem to cylinder sleeve piston, a kind of easy water tank is set to be installed on below the drilling pump pump housing, in water tank, be loaded with cooling water, adding in addition a water pump is communicated with water tank, when drilling pump is worked, start water pump, by water pump, the water in water tank is delivered in cylinder sleeve by water spray fitting device, to carry out cooling to cylinder sleeve piston.But the cooling water spray projector system of existing this drilling pump cylinder jacket piston, install numerous and diverse, cylinder sleeve inhomogeneous cooling is even, whole reciprocating stroke and cylinder sleeve upper part can not be fully cooling, and piston rod just plays the effect that connects power end and piston, and it is not very desirable making the cooling of cylinder sleeve piston.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of good cooling results, manufactures simply, reduces the operating time, cost-saving novel cooling drilling pump cylinder jacket piston connecting rod.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of novel cooling drilling pump cylinder jacket piston connecting rod, comprise piston rod body, described piston rod body lower end is provided with flange, described flange lower end is provided with piston coupling shaft, it is characterized in that: in described piston rod body, be provided with water transport channel, described flange wall is provided with spray hydrophthalmia.
As preferably, described spray hydrophthalmia is evenly distributed on described flange wall, and described spray hydrophthalmia has 6.
As preferably, described piston rod body upper end is provided with water supply connector, and described water supply connector and described water transport channel upper end connect.
As preferably, described water transport channel lower end and described spray hydrophthalmia connect.
As preferably, described water supply connector is connected with flexible pipe.
The beneficial effects of the utility model are: solved the cooling not good problem of spraying water, made that cylinder sleeve of drilling pump is cooling reaches comprehensive, and then cooling effect is more reliable, reduced cost of production, the workload that has reduced workman, has improved manufacturing efficiency, is suitable for extensive popularization.
