Abstract
The utility model discloses a rubber seal exchange tool of a magma pump piston which comprises a hydraulic manual pump; the manual pump is connected with a hydraulic cylinder through a hydraulic pipe; the utility model also comprises four bolts; an upper bottom cover, a lower bottom cover and a pressure cover are respectively sheathed in the bottom part, the middle part and the top part of each bolt by the holes on the upper bottom cover, the lower bottom cover and the pressure cover; the middle of the upper bottom cover is provided with a lug boss which can be matched with the piston hole of the piston of a rubber sleeve to be exchanged in a sliding way; holes matched with the hydraulic rod of the hydraulic cylinder in an inserting way are arranged in the position of the lug boss of the upper bottom cover and the inside of the lug boss; the hydraulic cylinder is arranged on the lower bottom cover; one end surface of the pressure cover is connected with a left arc lug boss and a right lug boss which can be wrapped and matched with the lug boss of the piston of the rubber sleeve to be exchanged; the bottom surface of the left arc lug boss and the right arc lug boss can be inosculated and matched with the shape of the tablet of the top surface of the rubber seal to be exchanged.
Description
Technical field
The utility model relates to a kind of more changing device, relates in particular to a kind of mud piston rubber seal and changes instrument.
Background technology
Slush pump is the capital equipment of oil recovery usefulness, because earth's crust pressure exists, there is the existence of flowing well at the oil well initial stage.But the later stage must be injected mud to other position in oil field and be kept earth's crust pressure, and slush pump is exactly the capital equipment that is used for injecting mud.The rubber seal of the piston of original this equipment is to adopt the rubber parts on the manual work mode clamping piston to take out the method that jump ring is changed sealing, but because rubber seal elasticity is very big, changing a rubber seal wastes time and energy.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can improve the operating efficiency of changing the piston rubber seal greatly, makes the piston rubber seal work a kind of mud piston rubber seal replacing instrument of safety labor-saving more of changing.
Instrument is changed in a kind of mud piston rubber seal of the present utility model, it comprises the hydraulic manual pump, described manual pump links to each other with a hydraulic cylinder by hydraulic tube, it also comprises at least four bolts, last bottom, lower bottom cover, gland is respectively by the borehole jack opened on it bottom at described each bolt, middle, the top, described go up is provided with the boss that can be slidingly fitted with the piston rod hole of the piston of rubber sleeve to be replaced in the middle of the bottom, bottom lug boss position and boss inside have the hole of inserting cooperation with the hydraulic stem of described hydraulic cylinder mutually on described, described hydraulic cylinder is arranged on the described lower bottom cover, an end face of described gland is connected with the left and right sides arc boss that can pack tightly cooperation with the boss of the piston of rubber sleeve to be replaced mutually, and the bottom surface of described arc left and right sides boss can match with the compressing tablet shape of the end face of rubber seal to be replaced and cooperate.
Adopt device of the present utility model can improve the operating efficiency of changing the piston rubber seal greatly, make and change piston rubber seal work safety labor-saving more.
Description of drawings
Accompanying drawing is the structural representation that instrument is changed in a kind of mud piston rubber seal of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done to describe in detail.
Instrument is changed in a kind of mud piston rubber seal of the present utility model as shown in drawings, it comprises hydraulic manual pump 1, described manual pump 1 links to each other with a hydraulic cylinder 3 by hydraulic tube 2, it also comprises at least four bolts 5, last bottom 6, lower bottom cover 4, gland 7 is respectively by the borehole jack opened on it bottom at described each bolt 5, middle, the top, described go up is provided with the boss that can be slidingly fitted with the piston rod hole of the piston 8 of rubber seal to be replaced in the middle of the bottom 6, bottom lug boss position and boss inside have the hole of inserting cooperation with the hydraulic stem of described hydraulic cylinder mutually on described, described hydraulic cylinder 3 is arranged on the described lower bottom cover 4, an end face of described gland 7 is connected with the left and right sides arc boss that can pack tightly cooperation with the boss of the piston 8 of rubber sleeve to be replaced mutually, and the bottom surface of described left and right sides arc boss can match with the compressing tablet shape of the end face of rubber seal to be replaced and cooperate.Adopt this device will go up bottom 6 jack-up, make compressing tablet on the piston 8 be glanded 7 and depress, thereby the rubber seal under the compressing tablet is steadily depressed, jump ring is taken off, change rubber seal with special-purpose jump ring pliers by hydraulic cylinder 3.
