Description
Technical field
The utility model is related to oil pumper field, more particularly to a kind of packing for novel oil extractor device.
Background technology
In oil pumper when using, as viscosity of crude increase, crude oil surface tension are increased substantially, back pressure resistance increases
Plus, slip increase, declined by sealing property, existing packing used for oil extractor cannot meet use demand, and structure is very unreasonable.
Utility model content
The utility model is directed to deficiencies of the prior art, there is provided a kind of rational in infrastructure, sealing property is high, connection
Close packing for novel oil extractor device.
The purpose of this utility model is to be achieved through the following technical solutions：
A kind of packing for novel oil extractor device, including beam hanger, main body, upper gland, gland, packing, support fixed cover, institute
Stating body interior has reinforcement seal groove, reinforcement seal groove inside connection reinforcement sealing ring, the reinforcement sealing ring top
Connection extruding block, the reinforcement seal groove top connects packing box mounting groove, the packing box mounting groove inside connection packing
Box, the packing box top connection support fixed cover, the support fixed cover upper inner connection packing box top, the packing
Box inside connection packing, the packing box lower inside has lower protection sealing ring, and the lower protection sealing ring lower potion connection is squeezed
Pressure block, the packing box inside upper part has upper protection sealing ring, the upper gland of upper protection sealing ring top connection.
The main body wall has locking engagement screw thread, and the main body connects lock sleeve, the lock sleeve bottom and locking
There is engagement screw thread intermeshing, the lock sleeve upper outside gland to engage screw thread.
The upper gland of gland inside connection, the gland bottom has screw channel, the screw channel connection lock sleeve top, institute
State screw channel and screw thread intermeshing is engaged with gland, the beam hanger sequentially passes through main body, strengthens sealing ring, extruding block, lower protection
Sealing ring, packing, upper protection sealing ring, upper gland, gland.
Beneficial effect：
Extruding block can effectively prevent from strengthening sealing ring in reinforcement seal groove inside shaking, improve imporosity,
Under upper protection sealing ring, lower protection sealing ring collective effect, when beam hanger is in packing and packing box internal motion, beam hanger is first
Contact protection sealing ring, it is ensured that packing box directly weares and teares, and then the sealing property of packing is ensure that, to packing box and disk
Root has carried out protective effect, at the same protect sealing ring also to packing box bottom with extrude block junction, packing box top with it is upper
Gland junction is sealed, and prevents fluid from being leaked from the joint gap of part, and protection sealing ring can not only play protection
Sealing property is high simultaneously for effect, reduces the wear rate of packing and packing box, and structure is more reasonable.This new pumping unit disk
Root device increased protection sealing ring, lower protection sealing ring on the inside of packing box, and it is close to be provided with reinforcement in packing box bottom
Seal, extruding block, by the common cooperation of above structure so that the sealing property of packing increases, and is consolidated to packing
When assembling surely, employing lock sleeve, support fixed cover carries out locking support so that overall structure is more completely embedded reliability.
Brief description of the drawings
Fig. 1 is a kind of packing for novel oil extractor apparatus structure schematic diagram described in the utility model.
Specific embodiment
The utility model is described in further detail below according to drawings and Examples：
A kind of packing for novel oil extractor device, including beam hanger 1, main body 2, upper gland 3, gland 4, packing 10, support are admittedly
Surely cover 13, the inside of the main body 1 has strengthens seal groove 5, the inside connection reinforcement sealing ring 6 of the reinforcement seal groove 5, it is described plus
The strong top of sealing ring 6 connection extruding block 7, extruding block can effectively prevent reinforcement sealing ring from strengthening being shaken inside seal groove
It is dynamic, improve imporosity, the top of the reinforcement seal groove 5 connection packing box mounting groove 8, inside the packing box mounting groove 8
Connection packing box, the top of the packing box 9 connection support fixed cover 13, the support fixed cover 13 upper inner connection packing box
9 tops, the inside of the packing box 9 connection packing 10, the lower inside of the packing box 9 has a lower protection sealing ring 11, it is described under
Protection sealing ring 11 bottom connection extruding block 7, the inside upper part of the packing box 9 has upper protection sealing ring 12, the upper guarantor
The upper gland 3 of shield sealing ring 12 top connection, under upper protection sealing ring, lower protection sealing ring collective effect, when beam hanger is in packing
During with packing box internal motion, beam hanger contact protection sealing ring first, it is ensured that packing box directly weares and teares, and then ensure that
The sealing property of packing, protective effect has been carried out to packing box and packing, at the same protect sealing ring also to packing box bottom with squeeze
Pressure block junction, packing box top are sealed with upper gland junction, prevent fluid from being let out from the joint gap of part
Leakage, protection sealing ring can not only play a protective role simultaneously sealing property it is high, reduce the wear rate of packing and packing box, structure
It is more reasonable.
The side wall of the main body 2 has locking engagement screw thread 14, the connection lock sleeve 15 of the main body 2, under the lock sleeve 15
Portion engages screw thread 14 and is intermeshed with locking, and there is the upper outside of the lock sleeve 15 gland to engage screw thread 16.
The upper gland 3 of the inside of the gland 4 connection, the bottom of the gland 4 has screw channel 17, the connection lock sleeve of the screw channel 17
15 tops, the screw channel 17 engages screw thread 16 with gland and is intermeshed, the beam hanger 1 sequentially pass through main body 2, strengthen sealing ring 6,
Extruding block 7, lower protection sealing ring 11, packing 10, upper protection sealing ring 12, upper gland 3, gland 4.This new pumping unit is used
Packing unit increased protection sealing ring, lower protection sealing ring in the inner side of packing box 9, and be provided with reinforcement in packing box bottom
Sealing ring, extruding block 7, by the common cooperation of above structure so that the sealing property of packing increases, and is carried out to packing
During fixed assembling, employing lock sleeve, support fixed cover carries out locking support so that overall structure is more completely embedded reliability.
