Abstract

The invention provides a thin-wall sliding sleeve disassembling fixture. The thin-wall sliding sleeve disassembling fixture comprises a puller nut and a puller screw. The puller screw is in threaded connection with the puller nut. One end of the puller screw is provided with a clamping jaw. The puller screw is in threaded connection with the clamping jaw. A bracket and a hydraulic system are installed between the puller nut and the clamping jaw. The bracket and the hydraulic system are sheathed on the puller screw. The bracket is adjacent to the clamping jaw. The hydraulic system is adjacent to the puller nut. Through controlling the hydraulic system to boost pressure and reduce pressure, the disassembly of a thin-wall sliding sleeve can be realized. The thin-wall sliding sleeve disassembling fixture is small in volume, light in weight, smooth and steady in movement, and safe and convenient in operation, and capable of preventing the deformation of the thin-wall sliding sleeve and thescratching of a hole wall in an disassembling process.

Description

technical field [0001] The invention relates to the field of hand tools for oilfield equipment, in particular to a thin-wall sliding sleeve removal tool. Background technique [0002] In oil field equipment, some thin-walled sliding sleeves or copper sleeves are often installed on the power end structure of some plunger pumps and other products to support the reciprocating linear motion of the piston or crosshead in it. For example, a cross-head sliding sleeve of a plunger pump, because the sliding sleeve is relatively thin, the wall thickness of one side is only 4-5mm, and the hole installed with it is an interference fit, which can be compressed by cold fitting and hydraulic tools during assembly. , the ordinary puller cannot be effectively disassembled during replacement, and the strong disassembly is likely to cause strain on the hole wall, which brings great difficulties to the disassembly of the thin-walled sliding sleeve. There is an urgent need for a type that can en...
