The interior diameter of side.In this way, after the packing protective device is connect with the second sub- packing box, which can effectively baffle
Packing in second sub- packing box is arranged in the packing closely in the second sub- packing box, plays effectively sealing
Effect.
By taking packing protective device shown in Fig. 3 as an example.When installing the packing box protective device, staff can first rotate
Gland for packing box removes gland for packing box across polished rod, then takes out packing in the first sub- packing box, rotates the first sub-disk root
Box is passed through polished rod and removes and remove the second jube, later, the first jube will be made to pass through polished rod from the lesser side of diameter, put
Set on the second sub- packing box, then packing protective device passed through into polished rod, by rotate the packing protective device by its with this
Two sub- packing boxs are threadedly coupled, and the second jube is passed through polished rod, is placed in packing protective device, the first sub- packing box is passed through
Polished rod, and rotating the first sub- packing box is threadedly coupled it with packing protective device, and packing is loaded to the first sub-disk root
In box, finally, rotation gland for packing box is pressed on packing in packing box, makes packing and polished rod seal, transmitted by lubricating fluid
Lubricating fluid is added in packing protective device by mouth, so far completes whole operation process.
Further, when the sealing structure of lubricating fluid transmission mouth is leakproof ball, grease gun is can be used in staff
Butter is transmitted mouth by the lubricating fluid to be added in packing protective device, when installing completion additional, extracts insertion lubricating fluid transmission
The grease gun head of mouth, leakproof ball can be realized the sealing to lubricating fluid transmission mouth, add in this way into packing protective device
The mode for filling lubricating fluid is simple, and it is convenient to operate.
In conclusion packing box protective device provided by the embodiment of the utility model, since the packing box protective device exists
With packing box be tightly connected after can accommodate lubricating fluid, the lubricating fluid can reduce polished rod in reciprocatory movement with packing it
Between frictional force, slow down the abrasion of packing, liquid spill and environmental pollution, extend packing caused by avoiding because of packing serious wear
Replacement cycle reduces production cost.Meanwhile the lubricating fluid have cooling characteristics when can reduce on polished rod because polished rod and packing rub
The temperature generated is wiped, influence of the temperature to polished rod plasticity is reduced.
As shown in Figure 1, the utility model embodiment provides a kind of packing box 1, which includes: above-mentioned packing
Protective device 14.
Further, packing box 1 further include: the second jube 13, gland for packing box 11, the first sub- packing box 12 and second
Sub- packing box 16.
Wherein, gland for packing box 11, the first sub- packing box 12, tubular body and the second sub- packing box 16 are successively detachable close
Envelope connection, for example, gland for packing box 11, the first sub- packing box 12, tubular body and the second sub- successively screwed connection of packing box 16.
There is the through-hole passed through for polished rod 3, which is arranged in the first sub- packing box 12 on second jube 13
Portion, positioned at one end that the tubular body of the first sub- packing box 12 and packing protective device 14 is tightly connected, the second jube 13 is matched
The packing 2 being set in the sub- packing box 12 of baffle first.
Optionally, which can be all the same with the shape and size of the first sub- packing box, then the packing is protected
Device can be obtained by the way that first packing box is transformed, it is only necessary to a lubricating fluid be arranged in the side-walls of the first sub- packing box and transmit
Mouthful, simplify the manufacturing process of the packing protective device, meanwhile, tubular body and the first sub- packing box shape and
When size is all the same, the first jube can be all the same with the shape and size of the second jube, protects without being specifically manufactured the packing
The first jube in protection unit, reduces the manufacturing cost of the packing protective device.
In conclusion packing box provided by the embodiment of the utility model, since the packing box is mounted with packing box protection dress
Set, and accommodated lubricating fluid in the packing protective device, the lubricating fluid can reduce polished rod in reciprocatory movement with packing
Between frictional force, slow down the abrasion of packing, liquid spill caused by avoiding because of packing serious wear, environmental pollution, extend packing
Replacement cycle, reduce production cost.Meanwhile the lubricating fluid have cooling characteristics when can reduce on polished rod because of polished rod and packing
Rub the temperature generated, reduces influence of the temperature to polished rod plasticity.
Further, when the density of the lubricating fluid (such as butter) in the packing box be greater than water when, the packing box be applied to pair
In the pumping unit that high-water-cut oil-producing well is exploited, since lubricating fluid density is larger, it is more effectively prevented from the thorn leakage of water, is enhanced
The leakproofness of the packing box.
