Description
Technical field
The utility model relates to the wall thickness screw rod stators of using in a kind of oil, the gas drilling field such as helicoid hydraulic motor stator, particularly a kind of shaped by fluid pressure.
Background technology
Helicoid hydraulic motor is a mud motor commonly used in oil, the gas drilling engineering; It comprises by-pass valve assembly, motor assembly, universal drive shaft assembly and driving-shaft assembly; Wherein motor assembly is the core component that power is provided for helicoid hydraulic motor, is made up of rotor and two essential parts of stator.Conventional motor stator is made up of stator case and rubber bushing, and the stator case inner chamber is the smooth face of cylinder, and rubber is bonded in the stator case inwall through sulfuration process, and the endoporus of rubber bushing is the continuous helical curved surface.In the course of work, under the extruding and rotor annular seal space differential pressure action of rotor cycle property, because the rubber bushing wall thickness does not wait; Inhomogeneous deformation will take place in rubber bushing, thereby cause the rubber bushing mechanical sealing performance to weaken, and influence motor operations efficient; Simultaneously because the heat radiation of the rubber bushing of conventional shape is uneven; Thermal hysteresis is serious, makes rubber very easily aging and tear, and reduces its useful life.
In recent years, proposed both at home and abroad to wait the wall thickness screw drilling tool motor stator, because the wall thickness of stator rubber lining is basic identical; The distortion of stressed back evenly; Resistance capacity to deformation is strong, and heat dispersion and sealing property improve, and has improved the operating efficiency and the useful life of helicoid hydraulic motor; But the same wall-thickness stator shell inner surface is the continuous helical curved surface, and difficulty of processing is big and cost is higher.Therefore, the research processing technology is simple, processing cost is lower, the helicoid hydraulic motor of high efficiency and long service life has important application value.
Summary of the invention
The purpose of the utility model is short in order to solve conventional screw drilling tool stator inefficiency, useful life, and etc. the difficult problem that wall thickness helicoid hydraulic motor stator difficulty of processing is big and cost is high, the spy provides wall thickness screw rod stators such as a kind of shaped by fluid pressure.
For achieving the above object, the utility model solves the technical scheme that this technical problem adopted and is: wall thickness screw rod stators such as a kind of shaped by fluid pressure, by stator case, rubber layer, shaped by fluid pressure stator and etc. wall thickness rubber etc. form; Stator case is the straight tube of inner wall smooth; Wall thickness rubber such as shaped by fluid pressure stator inner wall bonding one deck; Inject rubber layer between stator case and the shaped by fluid pressure stator, rubber layer rises and supports and cementation; Rotor cooperates the formation annular seal space with waiting wall thickness rubber; Press or external pressure in the shaped by fluid pressure stator uses, through shaped by fluid pressure straight tube is formed, its surfaces externally and internally is spiral camber.
The beneficial effect that the utlity model has is: wall thickness rubber such as (1) shaped by fluid pressure stator inner wall bonding one deck have been accelerated the radiating rate of stator, have improved the bearing capacity of stator intensity, annular seal space, and the operating efficiency of motor and useful life; (2) the shaped by fluid pressure stator forms straight tube through shaped by fluid pressure; Wall thickness rubber such as inwall bonding; Have the common advantage that waits wall thickness helicoid hydraulic motor stator, and the difficulty of processing and the processing cost of shaped by fluid pressure stator processing reduction same wall-thickness stator inside spin curved surface.
