Abstract
The utility model provides a diaphragm coupling for a solid control device, and the diaphragm coupling for a solid control device consists of a diaphragm coupling and a standard coupling guard, wherein the diaphragm coupling is composed of a pump end half shaft section, a middle section, a motor end half shaft section, a metal diaphragm and a connecting bolt. The pump end half shaft section is fixed on the pump shaft, and rotates with the pump together. The middle section is used for compensating the distance between the pump shaft and the motor shaft. The motor end half shaft is fixed on the motor shaft, and rotates with the motor together. The diaphragm coupling is the metal diaphragm coupling. Utilizing the diaphragm coupling and the standard coupling guard, the diaphragm coupling for the solid control device can degrade the influence of an ultimate state in natural environment on the performance of the coupling, and thereby enabling the coupling guard to conform to the requirements of the oil industry about the coupling guard security, and ensuring the safety of the site operation.
Description
Technical field
The utility model belongs to the solid control equipment field in the oil exploration, relates to a kind of solid control equipment diaphragm coupling, particularly a kind of metal diaphragm coupling.
Background technique
The employed coupling of drilling well solid control equipment is coupling with rubber pad at present, the torrid zone and frigid zone Kazakhstan area natural climate temperature range is from more than 60 degrees centigrade to subzero 50 degrees centigrade under the line, at high temperature deliquescing flexibility decrease of block rubber, follow the string and become fragile at low temperatures, the transmitting torque strength deficiency, the rubber material wear block, working life is short.Coupling shield does not meet 2 requirements of petroleum industry in the market: the one, and space length should put in a finger just between guard shield and the coupling, the 2nd, coupling shield can bear an individual weight approximately 100 kilograms operator trample and indeformablely do not damage, these defectives all serious threat to the safety of execute-in-place.
Summary of the invention
The utility model purpose is to provide a kind of solid control equipment with diaphragm coupling and standard coupling shield structure, satisfies the service behaviour of solid control equipment under abominable physical environment temperature, makes it meet the requirement about the site safety standard of PetroChina Company Limited..For reaching above-mentioned target, this solid control equipment forms with the coupling shield of diaphragm coupling by diaphragm, bolt, pump end half hub section, motor side half hub section and standard.Diaphragm coupling is by pump end half hub section, middle node, motor half hub section, two groups of metal diaphragms and connecting bolt is some is formed by connecting, pump end half hub section is to be fixed on the pump shaft, rotate together with pump, middle node is the spacing between compensation pump shaft and the motor shaft, and the angular displacement ability of increase diaphragm compensation, the motor side half hub section is to be fixed on the motor shaft, rotate together the moment of torsion transfer route with motor: motor shaft → motor side half hub section → motor side diaphragm → middle node → pump terminal membrane sheet → pump end half hub section → equipment axis.By such moment of torsion transmission, reach the purpose of motor driving apparatus, if exist between the diaxon misalign or angle on deviation, diaphragm itself can go compensation by modification.
Surround coupling in the coupling shield, prevent that operator from contacting the coupling of High Rotation Speed, when coupling bolt or damage parts flew out, coupling shield also can play the effect of protection.
Distance between standard coupling shield of the present utility model and the coupling is 15-18mm, be essentially the gap of a finger, this is an optimal size on the space, can give full play to the effect of coupling shield, coupling shield is high-strength steel plate stamping and forming, above having guaranteed that one heavily approximately 100 kilograms operator steps down in, guard shield is indeformable not to be damaged.
Diaphragm is metal material, and environment that can reform of nature high temperature low temperature guarantees the Security of coupling reliable operation and standard coupling shield; Diaphragm coupling can reform of nature high temperature low temperature environment, reach the reliable and stable requirement of operational effect; The standard coupling shield can reach accurate dimensional accuracy and enough intensity, satisfies the safe handling requirement that phenomenon is used; Behind the diaphragm coupling of employing solid control equipment and the coupling shield of standard, can reduce the ultimate state of physical environment to the performance impact of coupling, the use of standard coupling shield guarantees the Security of execute-in-place then so that coupling shield meets petroleum industry about the requirement of coupling shield secure context.
