Abstract
The utility model provides a high pressure water pump plunger sealing device, belongs to liquor pump technical field for solve traditional plunger sealing device sealing performance poor with the fast problem of the rate of wear, its technical scheme is, this sealing device includes two uide bushings, a plurality of graphite annulus and multiunit packing ring, they along high pressure water pump's plunger axial arrangement and suit on high pressure water pump's plunger, two uide bushings are arranged respectively at head end and tail end, a plurality of graphite annuluss and multiunit packing encircle interval arrangement between two uide bushings. The utility model discloses the graphite annulus and the packing that utilize the interval arrangement encircle the plunger to high pressure water pump to seal, have improved the wear -resisting of sealing device and sealing performance greatly, have prolonged sealing device's life to reduce the maintenance cost of equipment and maintenance personal's intensity of labour, guaranteed the normal operating of equipment.
Description
Technical field
The utility model relates to a kind of high reliability plunger sealing device for three plunger high-pressure water pumps, belongs to liquor pump technical field.
Background technique
At present, the plunger of three plunger high-pressure water pumps that iron and steel enterprise uses generally adopts chev(e)ron seal device, comprises a support ring, a pressure ring and multiple chev(e)ron seal ring.Because the reciprocating speed of high-pressure service pump plunger is very high, per minutely reach 235 times, therefore the rate of wear of plunger seal quickly, the sealing effect of sealed letter is caused to be had a greatly reduced quality, life cycle is very short, spare part expense, along with the aging continuous increase of equipment, has not only had a strong impact on the normal operation of equipment, and adds the labor intensity of maintenance man and the maintenance cost of equipment.
Model utility content
The purpose of this utility model is the drawback for prior art, provides a kind of high-pressure water pump plunger sealing device of high reliability, with the labor intensity of the maintenance cost and maintenance man that reduce equipment, ensures the normal operation of equipment.
Problem described in the utility model realizes with following technical proposals:
A kind of high-pressure water pump plunger sealing device, formation comprises two guide sleeves, multiple graphite annulus and many group packing rings, they along high-pressure water pump plunger axially-aligned and be sleeved on the plunger of high-pressure water pump, two guide sleeves are arranged in head end and tail end respectively, and multiple graphite annulus and many group packing rings are spaced between two guide sleeves.
Above-mentioned high-pressure water pump plunger sealing device, described graphite annulus arranges 3 ~ 4, and described packing ring arranges 2 ~ 3 groups, often organizes packing ring and comprises 2 ~ 8 packing rings.
The utility model utilizes spaced graphite annulus and the plunger of packing ring to high-pressure water pump to seal, substantially increase the wear-resisting of seal arrangement and sealability, extend the working life of seal arrangement, thus reduce the maintenance cost of equipment and the labor intensity of maintenance man, ensure that the normal operation of equipment.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
1, first guide sleeve in figure; 2, packing ring; 3, graphite annulus; 4, plunger; 5, the second guide sleeve.
Embodiment
The utility model provides a kind of high-pressure water pump plunger sealing device, sealing device is based on graphite annulus and packing ring, coordinate original guide sleeve, adjusting nut etc., solve the difficult problem that leaking and generating heat often appears in conventional high-tension water pump packing letter, the seal request of high speed reciprocal plunger can be met.
Referring to Fig. 1, the utility model is substantially the same with the replacing program that traditional herringbone seals, suppose that seal arrangement comprises three graphite annuluss 3 and two groups of packing rings 2, disassemble sealed letter, first guide sleeve 1 is pushed, then be a graphite annulus 3 successively, one group of (three or four) packing ring 2, a graphite annulus 3, one group of (three or four) packing ring 2, a graphite annulus 3, second guide sleeve 5 etc., wherein the quantity of packing ring 2 is determined according to the physical length of plunger 4, at present in the actual use of 9 high-pressure service pumps, 11 rings are there are, 13 rings and 14 rings, 3 kinds of situations.
Certain steel rolling mill's high-pressure water pump has employed more than 30 year, along with the continuous expansion (by originally producing hundreds of thousands ton per year to current annual capacity 1200000 tons) of throughput, the frequency of utilization of high-pressure water pump also improves constantly (standby to 7 the pumps productions even of current 6 pumps by original four-function three).The running of high load certainly will exacerbate the damage frequency of high-pressure service pump plunger seal, and plunger leaks and constantly occurs owing to sealing the fever phenomenon caused that ruptures.After transforming seal arrangement according to the utility model, high-pressure water pump normal operation, the problems referred to above are solved.
