Abstract
A sealing device for an intermediate rod of a plunger pump comprises an intermediate rod, an oil seal seat and a crude oil seal box, and also a simple oil seal box. The simple oil seal box is fixed on the oil seal seat through a bolt. An oil seal is arranged in the simple oil seal box. Sealing packing units are arranged in the crude oil seal box. An oil seal is increased in a crankcase, when the plunger pump moves back and forth, the oil taken out by the intermediate rod is scraped. Due to too much lubricating oil, the materials do not be aged due to high temperature and the service life is prolonged. Three sealing packing units are arranged in the crude oil seal box through reaming, thus the oil seeped through the oil seal is stopped by the packing units and the packing units are loosened or unloosened at any time according to circumstances so as to realize good sealing effect. Compared with the prior art, the material loss is greatly reduced, the maintenance working capacity is lowered, and the maintenance cost of the plunger pump is effectively decreased.
Description
Technical field
The utility model relates to sealed member, the especially seal arrangement at plunger pump intermediary bar position of petroleum industry water injection well with plunger pump.
Background technique
At present, in oil field flood pattern, generally use the plunger pump of various models, Jie's rod seal of its plunger pump is the main sealed member of equipment, the problem that exists is: the frizing position of oil sealing is a rubber material in the sealed member, can be in high speed operation because friction-produced high temperature and accelerated ageing causes oil sealing to lose seal action causes the oil sealing leakage to increase, lubrication oil consumption is serious, worsens the working condition of equipment.And oil seal replacement is frequent, can cause the post operation personnel labor intensity to strengthen, and pump efficiency reduces, and materials consumption is serious.
The model utility content
The technical problems to be solved in the utility model is at above-mentioned deficiency, a kind of high sealing performance is provided, reduces plunger pump Jie rod seal device of missing.
The utility model is taked following technical measures: a kind of plunger pump Jie rod seal device, comprise Jie's bar, oil sealing base, former oil sealing box, and also comprise a simple and easy oil sealing box, simple and easy oil sealing box is equipped with oil sealing by being bolted on the oil sealing base in the simple and easy oil sealing box; In the described former oil sealing box sealed packing is installed.
Former oil sealing box is equipped with three sealed packings through after the reaming.
The beneficial effects of the utility model are: at oil sealing of the inner interpolation of crankcase, when the plunger pump to-and-fro motion, the frizing effect that the oil that Jie's bar is taken out of both can play is again because lubricant oil is many, can not cause material aging, prolong working life because temperature is high.Former oil sealing box is through installing three sealed packings after the reaming, even there is oil can be blocked by packing by oozing out behind the oil sealing also, and packing can be according to circumstances degree of tightness at any time, to reach good sealing effect.Compared with prior art, the utility model reduces spillage of material greatly, and maintenance workload lowers, and has effectively reduced the maintenance cost of plunger pump.

Embodiment
As shown in the figure, a kind of plunger pump Jie rod seal device comprises Jie's bar 1, oil sealing base 4, former oil sealing box 5, also comprises a simple and easy oil sealing box 2, and simple and easy oil sealing box 2 is fixed on the oil sealing base 4 by bolt 7, in the simple and easy oil sealing box 2 oil sealing 3 is installed; Described former oil sealing box 5 is equipped with three sealed packings 6 through after the reaming.
Working procedure of the present utility model is: when the plunger pump to-and-fro motion, the oil sealing 3 that the oil that the motion of Jie's bar is taken out of is installed in the simple and easy oil sealing box 2 falls to scrape, because this oil sealing 3 is installed in crankcase inside together with simple and easy oil sealing box 2, and can among a small circle, carry out offset adjusted by bolt 7 according to the eccentric wear situation, the frizing effect that both can play, because lubricant oil is many, can not cause material aging again, prolong working life because temperature is high.Former oil sealing box 5 can be installed three sealed packings 6 through after the reaming, further blocks the oil that oozes out by oil sealing.Present technique is changed in inside by two original oil sealing sealings adds an oil sealing, uses the compound seal of three packing_seals outside.After making packing_seal into outside, can be blocked by packing even there is oil to ooze out also, and packing can be according to circumstances degree of tightness at any time, to reach good sealing effect.
