Description
Technical field
The utility model belongs to the spiral polish rod seal device of improvement, particularly pumpingh well of the ground oil production equipment pumpingh well polish rod seal device of recover petroleum.
Background technology
At present, the crude oil in the pumpingh well being drawn in the Fuel Tanking Unit of ground, generally all is to adopt the rod pump oil pumping system.In order to prevent crude oil leakage, in oil pumping process, must carry out effective seal to oil pumping polish rod.Traditional oil pumping polish rod sealing is that the rubber circle is installed in packing box, and the rubber valve is installed below packing box.Rubber circle and rubber valve all are vulnerable parts, on average will change 1-3 time weekly, and untimely replacing can cause oil and gas leakage, and contaminated environment makes oil and gas production reduce simultaneously again.Therefore, in oil pumping process, must carry out effective seal, in time change the rubber circle and the rubber valve of wearing and tearing oil pumping polish rod.When changing rubber circle and rubber valve, need to shut down, the oil gas in the emptying pit shaft needs motor device to cooperate.Labour intensity is big when changing sealing, has reduced oil and gas production, and working strength of workers is big.In addition, the poor performance of above-mentioned sealing device correction, polished rod is in motion process, and its center is difficult to overlap with the sealing device center, and polished rod often produces eccentric wear to seal, and seal durability is short.
The utility model content
The purpose of this utility model is to provide a kind of pumpingh well spiral polish rod seal device, and not only sealing performance is reliable, long service life, and when changing airtight and watertight padding, do not need to shut down, stop production, labour intensity is little, does not influence oil production rate.
The purpose of this utility model is achieved in that the spiral polish rod seal device of a kind of pumpingh well, bottom in pedestal is being provided with and polished rod through hole movingly, the top of through hole is being provided with obconic discharge chambe, the barrel that matches with screw rod is being set on the top of discharge chambe, on barrel, gland is installed by screw thread, the screw rod that has centre bore is installed in the barrel, its centre bore and polished rod are movingly, the shoulder block on screw rod top matches with the upper surface and the gland inner face of barrel respectively, the screw rod upper end of stretching out from the gland centre bore is being provided with handle, affixed charge pipe on the charging aperture of gland sidewall setting with spring propulsion, the through hole that matches with charge door is being set on the barrel wall, and the attic base and the seat cushion of pedestal lower end are installed on the fittings body by pressure cap.
The airtight and watertight padding of packing in barrel of the present utility model and discharge chambe is the rubber grain material, advances the rubber grain material by the screw rod rotating screw, and the rubber grain material of discharge chambe is compressed and polished rod seal.When needs are reinforced in barrel of the present utility model, the pumpingh well polished rod works on, only need open the end cap on the charge pipe, spring propulsion is released, the rubber grain material is added from charge pipe, load onto spring propulsion, the end cap of screwing on, charge pipe is rotated a certain angle, charging aperture on the gland and the through hole on the barrel is staggered, make barrel on the through hole sealing.Rotary handle makes the screw rod rotation that the rubber grain material is advanced into discharge chambe, and the rubber grain material is compressed and polished rod seal.In inserting the process of rubber grain, do not need to shut down, stop production, do not influence oil and gas production, it is very convenient to add airtight and watertight padding, and labour intensity is little, and sealing performance is reliable.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Accompanying drawing is a sectional structure schematic diagram of the present utility model.
The specific embodiment
The spiral polish rod seal device of a kind of pumpingh well, as shown in drawings, bottom in pedestal 4 is being provided with and polished rod 1 through hole movingly, the top of through hole is being provided with obconic discharge chambe 5, the barrel 10 that matches with screw rod 3 is being set on the top of discharge chambe 5, on barrel 10, gland 2 is installed by screw thread, the screw rod 3 that has centre bore is installed in the barrel 10, its centre bore and polished rod 1 are movingly, the shoulder block on screw rod 3 tops matches with the upper surface and gland 2 inner faces of barrel 10 respectively, screw rod 3 upper ends of stretching out from gland 2 centre bores are being provided with handle 17, affixed charge pipe 15 on the charging aperture of gland 2 sidewall settings with spring propulsion, on barrel 10 walls the through hole that matches with charge door is being set, the attic base 9 and the seat cushion 8 of pedestal 4 lower ends are installed on the fittings body 6 by pressure cap 7.Have in the pressure cap 7 in tuningout hole the tuningout chamber of diameter greater than attic base 9 diameters is being set, the diameter in pressure cap 7 tuningout holes is greater than the diameter of pedestal 4 posts that match with it, and the diameter in tuningout hole is less than the diameter of attic base 9.Because the attic base 9 of pedestal has certain tuningout space in pressure cap 7, when there is deviation at polished rod 1 and well head center, unscrew pressure cap 7, make polished rod 1 and well head centering with pipe wrench rotation pedestal 4, tighten pressure cap 7 then and get final product.Can carry out aligning correction easily, reduce airtight and watertight padding wearing and tearing, increase the service life.Spring propulsion is for to be installed with the pull bar 16 that the end has scraping wings 11 in the charge pipe 15 that has sealing cap 14, compression spring 12 is housed on pull bar 16, affixed the handle 13 from pull bar 16 ends that sealing cap 14 centre bores stretch out.When needs are annotated the rubber grain material in barrel 10, unload the sealing cap 14 on the charge pipe 15, extract spring propulsion out, can in charge pipe 15, feed in raw material, after filling it up with material, install spring propulsion in charge pipe 15, pass through screw rod 3 again when discharge chambe 5 advances the rubber grain material, spring propulsion is defeated material in barrel 10 successively.
