Description
Technical field
The utility model relates to a kind of fluid pressure type bailing well sealer for mouth, especially the fluid pressure type bailing well sealer for mouth of being made up of frizing lid, bearing, pressure cap, hydraulic cylinder, plunger, hydraulic pressure end socket, back-moving spring, sheath, lower contact.
Background technology
In present employed fluid pressure type packing box is provided with the level and smooth shape packing in hole or with packing be contained in plunger the tube in, its shortcoming is to dispose the Residual oil in the wire rope thread groove, and dismounting is extremely inconvenient, and the operation field environment pollution is serious, operating efficiency is low, and sealing effectiveness is relatively poor.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, convenient disassembly, sealing effectiveness is good, operating efficiency is higher and reduce the fluid pressure type bailing well sealer for mouth of operation field environment pollution.
For achieving the above object, fluid pressure type bailing well sealer for mouth of the present utility model is made up of frizing lid, bearing, pressure cap, hydraulic cylinder, plunger, hydraulic pressure end socket, back-moving spring, sheath, lower contact, and frizing lid and pressure cap are interior by the frizing housing that has been threaded; The inwall of frizing housing is provided with oil scupper vertically; The frizing housing respectively is equipped with pair of bearings in two ends up and down; The frizing packing that matches with wire rope is installed in the frizing housing; Rotary sleeve is installed in the middle of frizing packing and the frizing housing; The centre of frizing packing and two pairs of bearings respectively is equipped with a plain cushion; The master root is installed in hydraulic cylinder top inner chamber, and is installed in the upper end of plunger; The V-type oil sealing is housed respectively in the seal groove of hydraulic pressure end socket and plunger.
This frizing housing is divided into two lobes along the rectangular impulse waveform curve of axis direction, and is provided with oil scupper vertically at inwall.
Plain cushion, rotary sleeve and frizing packing rely on the bearing rotation in the frizing housing.
The connection of thread of hydraulic cylinder and hydraulic pressure end socket and plunger and lower contact is equipped with sealing ring.
The hole has the thread surface of many thread grooves and thread groove and wire rope to match in the frizing packing.
Leave certain interval in the middle of sheath and the lower contact.
After adopting this practical fluid pressure type bailing well sealer for mouth, because the frizing housing is divided into two lobes along the rectangular impulse waveform curve of axis direction, so dismounting is very convenient; Because the master root is installed in hydraulic cylinder top inner chamber, and is installed in the upper end of plunger, helps the dismounting and the replacing of master root; The hole has the thread surface of many thread grooves and thread groove and wire rope to match in the frizing packing, and relies on bearing to rotate in the frizing housing, can remove the pollution of interior Residual oil of wire rope thread groove and minimizing operation field environment; By Hydraulic Elements control compression master root swelling wire rope, and in the fluid pressure type bailing well sealer for mouth V-type oil sealing and sealing ring are installed, can make sealing effectiveness good.
Description of drawings
Accompanying drawing is fluid pressure type bailing well sealer for mouth half cut-away view.
Lower contact 1, plunger 2, sealing ring 3, back-moving spring 4, sheath 5, V-type oil sealing 6, hydraulic pressure end socket 7, fuel inlet fitting 8, hydraulic cylinder 9, master root 10, pressure cap 11, bleed off pipe 12, bearing 13, oil scupper 14, plain cushion 15, frizing housing 16, rotary sleeve 17, frizing packing 18, frizing lid 19, wire rope 20.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
The bailing well of fluid pressure type shown in accompanying drawing sealer for mouth, form by frizing lid 19, bearing 13, pressure cap 11, hydraulic cylinder 9, plunger 2, hydraulic pressure end socket 7, back-moving spring 4, sheath 5, lower contact 1, by the frizing housing 16 that has been threaded, the frizing housing 16 of the rectangular impulse waveform curve of two lobes is fixed together in frizing lid 19 and the pressure cap 11; The inwall of frizing housing 16 is provided with oil scupper 14 vertically, makes Residual oil flow to below the frizing housing 16 under gravitational effect; The frizing housing respectively is equipped with pair of bearings 13 in two ends about in the of 16; The frizing packing 18 that matches with wire rope 20 is installed in the frizing housing 16, and 18 li holes of frizing packing have the thread surface of many thread grooves and thread groove and wire rope 20 to match, and frizing packing 18 rotates on wire rope 20 by bearing 13; In the middle of frizing packing 18 and the frizing housing 16 rotary sleeve 17 is installed, prevents that frizing packing 18 and frizing housing 16 from rubbing; The centre of frizing packing 18 and two pairs of bearings 13 respectively is equipped with a plain cushion 15, remedies the bigger deficiency of bearing 13 endoporus; Master root 10 is installed in hydraulic cylinder 9 top inner chambers, and is installed in the upper end of plunger 2; V-type oil sealing 6 is housed respectively in the seal groove of hydraulic pressure end socket 7 and plunger 2; Hydraulic cylinder 9 and hydraulic pressure end socket 7 and plunger 2 are equipped with sealing ring 3 with the connection of thread of lower contact 1, prevent that fluid from revealing by screw thread; Sheath 5 and the lower contact 1 middle certain interval that leaves, sheath 5 protection plungers 2 are avoided mechanical damage, and lower contact 1 is connected with other bailing well mouth device.
During work, in the wire rope 20 descending processes, no pressure in the hydraulic cylinder, under the effect of back-moving spring 4, plunger 2 and master root 10 are in relaxation state, have reduced the descending resistance of wire rope 20, make that to carry oily instrument descending smoothly; In the wire rope 20 up processes, hydraulic cylinder 9 is by fuel inlet fitting 8 cut-in pressures, and plunger 2 moves upward, thereby compression master root 10 swelling wire rope 20 and hydraulic cylinder 9 reach the sealing of this device.No matter in the up or descending process of wire rope 20, all rotations on wire rope 20 of frizing packing 18, wipe the Residual oil that sticks on the wire rope 20 off, and inwall oil scupper 14 vertically by frizing housing 16, Residual oil is flow under gravitational effect below the frizing housing 16, flow out through bleed off pipe 12 again.
