Embodiment Construction
[0036] The present invention will be described in detail below with reference to the drawings and specific embodiments.
[0037] The drilling pump cylinder liner quick disassembly tool of the present invention has a structure such as Figure 2-4 As shown, a housing 22 is included. The housing 22 is provided with a hollow piston 17, and the hollow piston 17 is provided with a ring of protrusions 48 around its side wall. The protrusions 48 are in contact with the inner side wall of the housing 22. There is a hollow piston pressure plate 18 connected with the hollow piston 17, the other end of the housing 22 is fixedly connected with a gland 23 sleeved on the hollow piston 17, and the side of the housing 22 near the hollow piston pressure plate 18 passes through the housing 22 The inner side wall, the protrusion 48 and the hollow piston 17 enclose an oil chamber I 25. The side of the housing 22 close to the gland 23 is enclosed by the inner side wall of the housing 22, the protrusion...

The invention discloses a drilling pump cylinder sleeve quick disassembling-assembling tool. The drilling pump cylinder sleeve quick disassembling-assembling tool comprises a shell, and the interior of the shell is provided with a hollow piston in a sleeving mode; the hollow piston is provided with a circle of protrusions surrounding the side wall of the hollow piston, and the protrusions make contact with the inner side wall of the shell in an attached mode; one end of the shell is fixedly connected with a hollow piston pressure plate, and the other end of the shell is fixedly connected witha gland arranged on the hollow piston in a sleeving mode; an oil cavity I is defined by the inner side wall of the shell, the protrusions and the hollow piston on the side, close to the hollow pistonpressure plate, of the interior of the shell; an oil cavity II is defined by inner side wall of the shell, the protrusions, the hollow piston and the gland on the side, close to the gland, of the interior of the shell; and the shell is provided with an oil inlet I communicating with the oil cavity I, and the gland is provided with an oil inlet II communicating with the oil cavity II. According tothe drilling pump cylinder sleeve quick disassembling-assembling tool, the problems that in the prior art, cylinder sleeve replacement is high in labor intensity, and the working efficiency is low dueto the fact that the pump stopping time is long are solved.
Description
Technical field [0001] The invention belongs to the technical field of oil and gas drilling equipment, and relates to a tool for quick disassembly and assembly of a drilling pump cylinder liner. Background technique [0002] At present, in the field of oil and gas drilling equipment, drilling pumps are widely used as the heart of oil drilling rigs. The drilling pump realizes the suction and discharge of drilling fluid through the reciprocating movement of the piston in the cylinder liner, such as figure 1 As shown, including cylinder liner locking ring 1, cylinder liner 2, piston 3, clamp 4, frame 5, cylinder liner gland 6, cylinder liner flange 7, hydraulic cylinder assembly 8, piston assembly 9, cylinder Sleeve sealing ring 10, wear plate 11, connecting bolt 12, nut 13, when the piston reciprocates in the cylinder liner, due to the high temperature and high pressure of the mud, the pressure between the piston rubber and the cylinder liner is very large, and the hard particles i...
