Abstract
The utility model relates to an easy-to-detach mechanical sealing member of a mechanical seal device field, which is designed for aiming to the technical problems of easy damage and inconvenient maintenance in the existing sealing member. The utility model is characterized in that the end part of one segment of a shaft sleeve is sheathed with a fixed ring which is provided with a fixed screw, and the end part of the other segment of the shaft sleeve is connected with a spring seat and an O-shaped ring; the middle segment of the shaft sleeve, namely between the fixed ring and the spring seat, is provided with a positioning sheet, O-shaped rings, a gland nut, a stationary ring sealing gasket, a stationary ring, a moving ring, a moving ring seat, a spring and a driving pin. The easy-to-detach mechanical sealing member can be sheath with a pump shaft easily, and the axial rotation is stable. When an individual sealing part needs to replace, operation can be carried out on a workbench only by disassembling the whole shaft sleeve out of the pump shaft, therefore a large operating platform and a favorable working environment are created for maintainers. The utility model is also suitable for sealing other liquor pumps, and the design of the overall structure is reasonable.
Description
Technical field
The utility model relates to the mechanical seal device field, is a kind of detachable mechanical sealing spare.
Background technique
At present, mechanical sealing element is one of vitals of water pump class, plays and carries various liquid to stop the effect of leaking.But it is not too convenient that its deficiency is to install and remove, keeps in repair, overhauls.Usually be that an easily damaged parts has been broken, must remove a plurality of links and could replace this part that this phenomenon is to have increased routine work amount and labor intensity to them to miantainers." the plunger pump seal removing " that publishes in the patent documentation, its ZL patent No. 03208390.4 belongs to a kind of device that is applied to oil field oil recovery usefulness.This device is made up of jackscrew, swivel nut, plunger, plunger guide cover, Sealing, seal, and this device is the special tool of dismounting Sealing.And application number 200410049001.1, disclosed " Sealing " is to comprise a head and a band, head has a cavity that has aperture, and strap ends can pass this aperture, and bonding apparatus is arranged on and is used to engage band in the cavity ... " Sealing ".Although the related art scheme that discloses in the patent documentation is no lack of, do not publish water pump class detachable mechanical sealing spare as yet.
Summary of the invention
The purpose of this utility model provides a kind of detachable mechanical sealing spare, makes it can solve the maintenance man and overhauls inconvenience, the technical problem that labor intensity is bigger.The purpose of this utility model is to adopt following technological scheme to realize.
A kind of detachable mechanical sealing spare, the sealing part mainly is made up of retaining ring, set screw, location piece, gland nut, stationary ring sealing gasket, stationary ring, rotating ring, O shape circle, rotating seat, spring, spring seat, driving pin, axle sleeve, it is characterized in that at axle sleeve 15 it being to be placed on the water pump spindle, one section end at axle sleeve is with retaining ring 1, and retaining ring is provided with set screw 2; Another of axle sleeve section end connects spring seat 12 and O shape circle 14; The stage casing of axle sleeve promptly is provided with location piece 3, O shape circle 4, gland nut 5, stationary ring sealing gasket 6, stationary ring 7, rotating ring 8, O shape circle 9, rotating seat 10, spring 11, driving pin 13, O shape circle 14 between retaining ring 1 and the spring seat 12.
The concave station of described gland nut 5 is provided with location piece 3, and its recessed shoulder position is provided with O shape circle 4, and the groove position is provided with stationary ring sealing gasket 6 and stationary ring 7, and one section of its diametric plane is threaded; Stationary ring 7 contacts with rotating ring 8, and O shape circle 9 is set between rotating ring 8 and the rotating seat 10; In spring seat 12 and the rotating seat 10 driving pin 13 and spring 11 are set.
This detachable mechanical sealing spare is easy with the water pump spindle socket, axially spin stabilization.When indivedual obturators need to change, then only need whole axle sleeve split out water pump spindle, can on worktable, operate, created bigger operating platform and working environment preferably to the maintenance man.The utility model also is suitable for the sealing of other liquid pump, and its general structure design is reasonable, and higher popularization and application values is arranged.

Embodiment
Mode of execution is installed, is dismantled with the utility model, and working principle is an example.During installation as long as this ports of 15 labels of axle sleeve is pushed on the water pump spindle, along water pump spindle up to the end face of axle sleeve with till water pump body contacts.The contacted while gland nut 5 that puts in place has also just been run into water pump body, water pump body herein is provided with internal thread, the real nuts of gland nut 5 for the band external screw rod, its spiro rod section screws in the most end of water pump body internal thread, and tightening soon by set screw 2, gland nut and water pump are connected as a single entity.Convenient disassembly refers to unscrew set screw 2, withdraws from gland nut 5, and whole Sealing just " has removed ".
Sealing principle: axle sleeve 15 is inserted in water pump spindle and tightens set screw 2 location by gland nut 5, and Sealing has just connected as one with water pump body.Drive the water pump spindle rotation during starting mode of pump, for stoping moving axially of Sealing on this section water pump spindle, rotate by water pump spindle and to make that rotating ring 8 and stationary ring 7 produce the relative dynamic frictions, the effect of the sealing of fitting.Because of rotating ring 8 rotations are to be connected transmission with spring seat 12 by driving pin 13 by axle sleeve 15, the elastic force that spring 11 provides passes to rotating ring 8 by rotating seat 10 and O shape circle 9, and rotating ring and stationary ring 7 are fitted tightly.Stationary ring 7 is to be interference fitted on the gland nut 5 with stationary ring sealing gasket 6, the location piece of making by teflon 3 again, and retaining ring 1 and set screw 2 spacing moves axially so further limit the integral body of Sealing.O shape circle 4 is effects of playing gland nut 5 and water pump body sealing, and 14 on O shape circle plays with water pump spindle and is sealed into pair, and radially preventing to go out is main effect, and because of teflon location piece 3 no axial forces, and the self-lubrication performance is better during dismounting, so must not pull down.Omitted the drafting of water pump body, water pump spindle among Fig. 1, described rotating ring 8, rotating seat 10, spring seat 12 right side structures are identical, but are plotted as asymmetricly, are to belong to the original characteristics of structure, in addition in order to know that due to the reflect structure feature, the spy is illustrated.
