Abstract
The utility model discloses a kind of pumping plant plunger labyrinth type flushing mechanisms, including plunger and stuffing box body, cooling water inlet and cooling water outlet are offered on stuffing box body, the stuffing box body is set on plunger, the both ends of plunger reach the outside of stuffing box body, the threaded one end of stuffing box body is connected with swivel nut, swivel nut is set on plunger, the other end of stuffing box body, which bends inwards out one, stops circle portion, and preceding guide sleeve, several preceding sealing rings, rear guide sleeve and rear sealing ring are arranged with successively from the front to the back on one section of plunger in stuffing box body；The cooling water inlet and cooling water outlet is arranged outside the rear guide sleeve on one section of stuffing box body；The drainage trough of at least one connection cooling water inlet and cooling water outlet is offered on the rear guide sleeve；Advantageous effect：Cooling water also cools rear guide sleeve in addition to cooling plunger, other than reducing plunger surface temperature, also increases plunger lubrication, overcomes plunger stem wear problem, extend the service life of sealing ring.
Description
Technical field
The utility model is related to a kind of pumping plant piston structure, more particularly to a kind of pumping plant plunger labyrinth type flushing mechanism.
Background technology
The service life of pumping plant plunger sealing washer, is always a long-standing problem, and especially present pumping plant uses pressure
Higher and higher, this problem is more and more in the urgent need to address.
By analysis, the main reason for sealing ring service life is low, is：Plunger and sealing ring at work, due to abrasive forces
And the amount of heat generated, and rear end or dry wear, it takes rationally cooling for main cause and increases lubrication, you can is big
It is big to improve sealing ring service life.
Utility model content
Technical problem to be solved in the utility model is in view of the deficiencies of the prior art, to provide a kind of pumping plant plunger labyrinth
Type flushing mechanism.
To achieve the goals above, the measure that the utility model is taken：
A kind of pumping plant plunger labyrinth type flushing mechanism, including plunger and stuffing box body offer cooling water on stuffing box body
Import and cooling water outlet, the stuffing box body are set on plunger, and the both ends of plunger reach the outside of stuffing box body, fill out
The threaded one end of material letter body is connected with swivel nut, and swivel nut is set on plunger, and the other end of stuffing box body bends inwards out a resistance
Baffle ring portion, be arranged with successively from the front to the back on one section of plunger in stuffing box body preceding guide sleeve, several preceding sealing rings, rear guide sleeve and after
Sealing ring；
The cooling water inlet and cooling water outlet is arranged outside the rear guide sleeve on one section of stuffing box body；
The drainage trough of at least one connection cooling water inlet and cooling water outlet is offered on the rear guide sleeve；
The drainage trough is arranged close to plunger；
The drainage trough was around plunger at least one week.
The beneficial effects of the utility model：Practicality, production cost is low, structure novel, and cooling water is also cold in addition to cooling plunger
Rear guide sleeve also increases plunger lubrication, overcomes plunger stem wear problem, extend other than reduce plunger surface temperature
The service life of sealing ring.
Description of the drawings
Fig. 1, the planar structure schematic diagram of the utility model.
Specific implementation mode
A kind of pumping plant plunger labyrinth type flushing mechanism, including plunger 1 and stuffing box body 2 offer cooling on stuffing box body 2
Water inlet 2-1 and cooling water outlet 2-2, the stuffing box body 2 are set on plunger 1, and the both ends of plunger 1 reach stuffing-box
The threaded one end of the outside of body 2, stuffing box body 2 is connected with swivel nut 3, and swivel nut 3 is set on plunger 1, the other end of stuffing box body 2
Bend inwards out a blocking circle portion 2-3, guide sleeve 4 before being arranged with successively from the front to the back on one section of plunger 1 in stuffing box body 2,
Several preceding sealing rings 5, rear guide sleeve 6 and rear sealing ring 7.
The cooling water inlet 2-1 and cooling water outlet 2-2 is arranged on the stuffing box body 2 of 6 one section of outside of rear guide sleeve.
The drainage of at least one connection cooling water inlet 2-1 and cooling water outlet 2-2 is offered on the rear guide sleeve 6
Slot.
The drainage trough is arranged close to plunger 1.
The drainage trough was around plunger 1 at least one week.
In the utility model, drainage trough can also be the structure of labyrinth form.When cooling water by cooling water inlet 2-1 into
When entering the utility model, drainage trough is flowed into, by drainage trough, cooling water also cools rear guide sleeve other than cooling plunger 1
6, other than reducing by 1 surface temperature of plunger, also increases plunger 1 and lubricate.1 dry wear of plunger is avoided, 5 He of sealing ring before extending
The service life of sealing ring 7 afterwards.
