Abstract
The utility model discloses a novel bailing type barrel oil pump. The novel bailing type barrel oil pump mainly comprises an upper joint, a limiting oil passing ring, a connecting rod, an oil passing groove, a rubber barrel upper pressing cover, an upper rubber barrel, a rubber barrel connecting sleeve, a lower rubber barrel, a guide sealing head, a lower joint and a limiting blocking platform. The novel bailing type barrel oil pump is characterized in that in the assembling mode, the connecting rod and the lower joint are connected and locked by threads; the guide sealing head, a lower rubber sleeve, the rubber barrel connecting sleeve, an upper rubber sleeve and the rubber barrel upper pressing cover are connected in sequence in a threaded manner, and then are sheathed into the connecting rod, the limiting oil passing ring is connected onto the connecting rod in a threaded manner, and then the upper joint is screwed and locked into the connecting rod above the limiting oil passing ring in a threaded manner; and the oil passing groove 4 and the limiting blocking platform are arranged on the periphery of the connecting rod. The novel bailing type barrel oil pump disclosed by the utility model has the beneficial effects that the sealing performance and the production efficiency are improved, the defect of dirt leakage after a steel ball and a ball seat are worn is overcome, and the use efficiency is increased.
Description
Technical field:
The utility model belongs to the OFME technical field, is meant a kind of novel bailing formula barrel oil pump concretely.
Background technology:
Bailing formula barrel oil pump is used for the bailing formula producing well at oilfield exploitation, is used for bailing formula oil pumping operation and uses, barrel oil pump and annular seal space and weighted lever link; Play the oil pumping function; Existing barrel oil pump has some problems such as worn steel ball, causes that single oil recovery wastage is big, system effectiveness is low, needs the regular replacing barrel oil pump of operating personnel; Strengthened the cost of production of oil recovery factory, brought many unnecessary troubles to the oil recovery factory.
The utility model content:
Cause in order to solve existing barrel oil pump worn steel ball that single oil recovery wastage is big, system effectiveness is low; Need the regular replacing barrel oil pump of operating personnel, strengthen the cost of production of oil recovery factory, bring the problem of many unnecessary troubles to the oil recovery factory; The utility model provides a kind of novel bailing formula barrel oil pump; This utility model has improved sealing performance and production efficiency, has overcome the deficiency that has dirt to miss after the wearing and tearing of steel ball and ball seat, has promoted service efficiency.
The utility model solves the technical scheme that its technical problem adopted: a kind of novel bailing formula barrel oil pump; Mainly comprise top connection, spacing oil ring excessively, connecting rod, cross oil groove, packing element upper press cover, go up packing element, packing element adapter sleeve, lower rubber cylinder, pilot seal head, lower contact, limiting block platform; It is characterized in that: fit; Earlier connecting rod and lower contact are locked with screwed connection; Connect gum cover, packing element adapter sleeve, last gum cover, packing element upper press cover under the pilot seal head with the mode of screw thread successively; Be inserted in connecting rod after connect accomplishing, the spacing oil ring of crossing be connected on the connecting rod with the mode of screw thread, afterwards top connection is screwed in the form of screw thread on the spacing connecting rod of crossing above the oil ring locked; Oil groove 4 and limiting block platform were arranged on the connecting rod circumference.
The beneficial effect of the utility model is, improved sealing performance and production efficiency, overcome the deficiency that the dirt leakage is arranged after the wearing and tearing of steel ball and ball seat, promoted service efficiency.
Description of drawings:
Fig. 1 is the utility model structural representation.
Among the figure: top connection 1, spacingly cross oil ring 2, connecting rod 3, cross oil groove 4, packing element upper press cover 5, go up packing element 6, packing element adapter sleeve 7, lower rubber cylinder 8, pilot seal 9, lower contact 10, limiting block platform 11.
The specific embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is further specified
A kind of novel bailing formula barrel oil pump; Mainly comprise top connection 1, spacingly cross oil ring 2, connecting rod 3, cross oil groove 4, packing element upper press cover 5, go up packing element 6, packing element adapter sleeve 7, lower rubber cylinder 8, pilot seal 9, lower contact 10, limiting block platform 11; Fit; Earlier with connecting rod 3 and lower contact 10 with screwed connection locking, successively pilot seal 9, down gum cover 8, packing element adapter sleeve 7, go up gum cover 6, packing element upper press cover 5 connects with the mode of screw thread, connect to be inserted in connecting rod 3 after accomplishing; The spacing oil ring 2 of crossing is being connected on the connecting rod 3 with the mode of screw thread, afterwards top connection 1 is screwed in the form of screw thread on the spacing connecting rod of crossing above the oil ring 23 locked; Oil groove 4 and limiting block platform 11 were arranged on connecting rod 3 circumference.
The oil pumping principle: barrel oil pump pumps in the oil pipe well in the work.When descending, borehole pressure promotes pilot seal 9, lower rubber cylinder 8, packing element adapter sleeve 7, goes up packing element 6, packing element upper press cover 5 is up, opens to cross oil groove 4 on the connecting rod 3, and liquid passed through oil groove 4 and gets into the barrel oil pumps upper end, and the barrel oil pump assembly is descending smoothly; During up oil pumping, head of liquid with packing element upper press cover 5, go up packing element 6, packing element adapter sleeve 7, lower rubber cylinder 8, pilot seal 9 and push sealed lower to and cross oil groove 4, the packing element envelope that expands under pressure realizes the oil pumping purpose.
Spacing principle: instantly glue head 8, may wear under the situation to a certain degree, prevent play during the oil pumping of up barrel oil pump that glue head 8, compressed cause the effect and the limiting pressure of unlimited expansion to cause unnecessary damage to play the position limitation protection effect to the barrel oil pump miscellaneous part.
The beneficial effect of the utility model is, improved sealing performance and production efficiency, overcome the deficiency that the dirt leakage is arranged after the wearing and tearing of steel ball and ball seat, promoted service efficiency.
