Description
Technical field
The utility model belongs to middle open type mechanical sealing device used for pump, especially a kind of middle open type pump packaging type welding gold
Belong to bellows axle envelope combination sealing arrangement.
Background technique
The behaviour in service of middle open type mechanical seal for pump is complicated, is letting out between the gland and cavity of middle open type pump first
Face is opened in leakage and middle open type pump, because middle open type pump is all casting and forming, most of middle open type pump is all packing seal,
Axis or axle sleeve, often appearance failure and damage, especially on response generalization construction equipment, or have in medium wherein and solidify
Or in the equipment of phenomena such as weak corrosion, axis or boss failure situation are especially prominent.The main original that many middle open type pumps are scrapped
Because be because packing seal has damaged axis or axle sleeve, in order to replace axis or axle sleeve, and the pump case that frequently disintegrates, cause in open face
It is scrapped caused by abrasion.
Utility model content
The purpose of this utility model is to provide a kind of combination of middle open type pump packaging type welded metal bellow axle envelope is close
Seal apparatus, structurally reasonable, easily fabricated installation can be improved the mechanical sealing effect of middle open type pump, improve middle open type machine
The service life of pump.
Purpose of the utility model is realized as follows: a kind of middle open type pump packaging type welded metal bellow axle envelope group
Sealing device is closed, including being coupled impeller positioning shaft sleeve in the shaft of middle open type pump, in the outer of impeller positioning shaft sleeve
Portion is coupled the integrated sealing chamber being made of integrated sealing seat and gland, in the impeller locating shaft being located in seal chamber
The sealing axle sleeve for being fixedly mounted with and being provided with integrated mechanical sealing assembly is put on, opens face phase in integrated sealing seat and pump shell
The terminal pad of cooperation, integrated sealing seat is packed in integrated sealing seat by the fixed pin being uniformly arranged on its circle end face
On pump shell, labyrinth seal groove is set on the shaft hole inner wall of integrated sealing seat cone.
The utility model is removed with by original dissection type seal chamber, processes the seal chamber of an entirety, seal chamber bottom
Portion machined included labyrinth seal supplementary structure, and especially with the labyrinth seal of cavity bottom integral type is used, it can
To be effectively reduced the pressure in seal chamber, sealing effect is improved, and reduce workload, avoided because packing seal is worn
Axis or axle sleeve, for replacement axis or axle sleeve and the pump case that frequently disintegrates, cause in open surface wear, leakage leads to the premature report of pump
It is useless.The utility model structure is simple, easily fabricated installation, can be improved the mechanical sealing effect of middle open type pump, reduces enterprise
Production cost.
The relevant criterion of cavity data fit API610 outside the axle sleeve positioned to impeller, and attached an axle sleeve,
The effect of this axle sleeve is need to only to remove the bearing retainer at both ends in shaft sealing leakage in this way in order to which the packaging of integrated mechanical sealing is used
Frame replaces dynamic and static ring later by integrated mechanical sealing overall pulling down, resets, and does not have to disintegration pump case, and advantage is that filler is close
Envelope, which is changed to mechanical seal, reduces the abrasion of axis or axle sleeve, extends service life, does not have to disintegration pump case, so that it may safeguard
Mechanical seal, because pump case it is frequent disintegrate caused by open the damage leakage of sealing surface due to it is premature scrap, extend middle open type
The service life of pump.
The utility model is structurally reasonable, easily fabricated installation, improves the mechanical sealing effect of middle open type pump, improves
The service life of middle open type pump.
Detailed description of the invention
The utility model is further described below in conjunction with attached drawing, Fig. 1 is the signal of the utility model front view structure
Figure.
Specific embodiment
A kind of middle open type pump packaging type welded metal bellow axle envelope combination sealing arrangement, as shown in Figure 1, in being included in
It is coupled impeller positioning shaft sleeve 1 in the shaft of open type pump, is coupled in the outside of impeller positioning shaft sleeve 1 by one
The integrated sealing chamber that formula seal receptacle 2 and gland 3 are constituted, is fixedly mounted with setting on the impeller positioning shaft sleeve 1 being located in seal chamber
There is the sealing axle sleeve 4 of integrated mechanical sealing assembly 5, integrated sealing seat 2 is matched with the face of opening in pump shell, integral type
The terminal pad of seal receptacle 2 makes integrated sealing seat 2 be packed in pump shell by the fixed pin 6 being uniformly arranged on its circle end face
On, labyrinth seal groove 8 is set on the shaft hole inner wall of 2 cone of integrated sealing seat.Pass through bearing on impeller positioning shaft sleeve 1
Bracket engagement is installed with integrated mechanical sealing assembly.Integrated mechanical sealing assembly by stationary ring, rotating ring, stretch compensation mechanism and
Sealing ring is constituted.The stationary ring of integrated mechanical sealing assembly is matched by sealing ring with the ladder platform of 3 axis hole of gland.In impeller
Positioning shaft sleeve sealing ring 9 is set on 1 end outer wall of positioning shaft sleeve.It is set on the circle end face of 2 terminal pad of integrated sealing seat
Set the terminal pad sealing ring 7 matched with the face of opening in pump.
