Abstract
The utility model discloses a tensioning device for feed inlets of oil delivery pumps with bent levers, which comprises two support seats. Two steel cylinders with internal threads are fixedly connected onto each support seat at intervals and perpendicular to the support seat, a double-end stud is connected between each two steel cylinders on the same side of the two support seat, a through hole is disposed in the center of one support seat, a positioning sleeve is arranged in the center of the other support seat, a threaded ejector rod is arranged in the positioning sleeve, and the outer side end of the threaded ejector rod extends out from the support seat. The tensioning device is simple in structure, during usage, the support seat with the through hole is mounted on a feed inlet and fixed by four bolts, the distance of the other support seat is adjusted, the threaded ejector rod rotates, and the feed inlet of a pump with a bent lever can be taken out easily.
Description
Technical field
The utility model relates to a kind of oil transportation curved bar pump charging aperture auxiliary extracting tool, particularly oil transportation curved bar pump charging aperture chest expander.
Background technology
At present the curved bar pump gets into charging aperture because of stator rubber usually occurs after coming unstuck; Charging aperture, stator and rotor etc. such as can not get at problem, because the pump house pipeline is many, the narrow and small operation in space is inconvenient; Perplex field engineering technical staff and oil recovery employee always, becoming a hard nut to crack of cost waste.Also want a complete set of equipment of frequent change pump simultaneously, rate when influencing oil transportation causes the waste of human and material resources, resource.The method of taking at present is with the bottle opener sled or adopts the sparking ticket after burning burnt rubber, to take out; Charging aperture reduces through burning back Material Strength and surface smoothness, and the life-span reduces, and then need change a complete set of equipment of pump if need in time resume production; When operation, waste time and energy cost of idleness.There is following problem in this working condition: the one, hurt sb.'s feelings easily during operation, and dangerous; The 2nd, workload is big, difficult installation; The 3rd, in waste of manpower, time, material, also cause problems such as the maintenance process is delayed time, extension, and installation quality is defective, had a strong impact on the ordinary production in oil field.
Summary of the invention
The purpose of the utility model is to provide a kind of oil transportation curved bar pump charging aperture chest expander, and it is simple in structure, can fast and effeciently dismantle curved bar pump charging aperture, and is time saving and energy saving, easy to use.
The purpose of the utility model is to realize like this; A kind of oil transportation curved bar pump charging aperture chest expander, this instrument comprises two supporting seats, all at interval affixed two steel cylinders with internal thread on every supporting seat; Steel cylinder and supporting seat are perpendicular; Connecting a studs between the homonymy steel cylinder of two supporting seats respectively, the center of a supporting seat is being provided with through hole therein, in the center of another supporting seat positioning sleeve is being set; A threaded mandrel is being set in the positioning sleeve, and the outboard end of threaded mandrel stretches out from this supporting seat.
The utility model is simple in structure, and the supporting seat that will have through hole during use is installed on the charging aperture, fixes with four bolts, adjusts the distance of another supporting seat, and the rotary threaded push rod can easily take out curved bar pump charging aperture.This device 1, be applicable to that oil field gas injection station, oil producing operation district, collection are defeated, the maintenance of the curved bar pump of sewerage.2, be applicable to pump types such as QGB380.2, QGB380.3, QGB750.3, QGB1450.3.3, be applicable to long-time charging aperture that does not take out and rotor etc.The utility model charging aperture chest expander is safe and reliable, easy to operate, save manpower, save time, and economizes on the use of funds, and reduced maintenance cost and maintenance time, improved employee's operating efficiency, improved the oilfield economic benefit.
Description of drawings
To combine accompanying drawing that the utility model is done further detailed explanation below.
Fig. 1 is the main TV structure sketch map of the utility model.
The specific embodiment
A kind of oil transportation curved bar pump charging aperture chest expander; As shown in Figure 1, this instrument comprises two supporting seats 1,6, all at interval affixed two steel cylinders with internal thread on every supporting seat; I.e. at interval affixed two steel cylinders 2 on supporting seat 1, affixed at interval two steel cylinders 5 on supporting seat 6.Steel cylinder 2,5 and supporting seat 1,6 are perpendicular.Connecting a studs 3 between the homonymy steel cylinder of two supporting seats 1,6 respectively, Rotating Double header stud 3 can be regulated two supporting seats 1, the distance between 6.The center of a supporting seat 1 is being provided with through hole therein, and this through hole supplies the rotor of curved bar pump to pass.In the center of another supporting seat 6 positioning sleeve 4 is being set, the caliber of positioning sleeve 4 is greater than the external diameter of curved bar pump rotor.A threaded mandrel 7 is being set in the positioning sleeve 4, and the outboard end of threaded mandrel 7 stretches out from this supporting seat 6.
The utility model is simple in structure, and the supporting seat 1 that will have through hole during use is installed on the curved bar pump charging aperture, fixes with four bolts, adjusts the distance of another supporting seat 6, and rotary threaded push rod 7 can easily take out curved bar pump charging aperture.
