Abstract
The utility model relates to a sealing device, in particular to a sealing device for a polymer-injecting pump. According to the technical scheme, the sealing device for the polymer-injecting pump comprises a pump rod, a sealing end cover, a bearing, a sealing ring, a sealing packing hole, a pressure relief hole and a shaft sleeve. The pump rod is sleeved with the shaft sleeve, the sealing end cover is fixed to the upper portion of the shaft sleeve, the sealing ring and the bearing are arranged between the pump rod and the shaft sleeve, the sealing packing hole and the pressure relief hole are formed outside the shaft sleeve, and the sealing ring is externally communicated with the sealing packing hole. The sealing device for the polymer-injecting pump has the advantages that by using the device, operation is easy and convenient, and the workload is reduced; meanwhile, working pressure of the pump rod is greatly reduced, service life of oil seals is prolonged, the leakage amount of lubricating oil is reduced, the number of times for routing inspection is reduced, safety is improved, and labor intensity of workers is reduced.
Description
One, technical field
The utility model relates to a kind of seal arrangement, particularly a kind of polymer-injecting pump seal arrangement.
Two, background technique
The pump rod oil sealing that the poly-station of note is used at present generally adopts jump ring or bolt to be fixed, and belongs to fixed seal arrangement.There is following defect in this device: when slight eccentric wear occurs bent axle, easily cause pump rod scratch, oil sealing aging, and cause oil sealing to be missed when serious, original device can not correspondingly be adjusted according to the variation of wastage, replacing difficulty is large, has both wasted Master Cost, has increased again workman's labor intensity, also extend the termination of pumping time, affected the poly-effect of note.
Three, summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of polymer-injecting pump seal arrangement is provided.
Its technological scheme is: comprise pump rod, end cover, bearing, seal ring, stuffing box packing hole, pressure relief vent, axle sleeve, the outside of pump rod is provided with axle sleeve, the top fixing seal end cap of described axle sleeve, between pump rod and axle sleeve, be provided with seal ring and bearing, the outside of axle sleeve is provided with stuffing box packing hole and pressure relief vent, the outside communication seals stuffing hole of described seal ring.
The beneficial effects of the utility model are: by using this device, simple to operation, reduce workload.Greatly reduced the working pressure of pump rod simultaneously, extended oil sealing working life, reduced lubricant oil wastage, patrolled and examined number of times and reduce, Security improves, and has reduced worker's labor intensity.
Four, accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: pump rod 1, end cover 2, bearing 3, seal ring 4, stuffing box packing hole 5, pressure relief vent 6, axle sleeve 7.
Five, embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises pump rod 1, end cover 2, bearing 3, seal ring 4, stuffing box packing hole 5, pressure relief vent 6, axle sleeve 7, the outside of pump rod 1 is provided with axle sleeve 7, the top fixing seal end cap 2 of described axle sleeve 7, between pump rod 1 and axle sleeve 7, be provided with seal ring 4 and bearing 3, the outside of axle sleeve 7 is provided with stuffing box packing hole 5 and pressure relief vent 6, the outside communication seals stuffing hole 5 of described seal ring 4.
By using this device, simple to operation, reduce workload.Greatly reduced the working pressure of pump rod simultaneously, extended oil sealing working life, reduced lubricant oil wastage, patrolled and examined number of times and reduce, Security improves, and has reduced worker's labor intensity.
