Description
Technical field
This utility model relates to transh pump technical field, more specifically, particularly to a kind of high-chromium wear-resistant
Alloy ore pulp transh pump.
Background technology
China's black, nonferrous mine need ore pulp transh pump and flow passage components thereof about 160,000 tons every year.Ore pulp
Transh pump is very strong in corrosivity, uses, both required wear-resisting, also requirement in dense acid ore pulp
Corrosion-resistant.As a example by China's Anshan iron and steel plant mine, once used ceramic pump and rubber lining pump, all due to insufficient strength,
Frangible, serviceability is poor and can not large quantities of apply.Also the world of CIimax company of the U.S. was introduced during this
Famous brand 15Cr3Mo ore pulp transh pump did on probation, had only used 288h i.e. to scrap.
The application of YN high-chromium wear-resistant alloy material, extends the service life of transh pump greatly, but existing
Some transh pumps are relatively big owing to containing solid particle in the ore pulp of conveying, the countershaft and corrosion of sealing and abrasion
Will be more serious, shorten the service life sealing structure greatly, and seal structure and once lost efficacy, the most straight
Connect the personal safety of the properly functioning even operator affecting pump.For this reason, it is necessary to design one
The high-chromium wear-resistant alloy ore pulp transh pump that follow-on, sealing property is excellent.
Utility model content
The purpose of this utility model is the high-chromium wear-resistant alloy ore pulp impurity providing a kind of sealing property excellent
Pump.
In order to solve posed problems above, the technical solution adopted in the utility model is:
A kind of high-chromium wear-resistant alloy ore pulp transh pump, including the pump housing, seal receptacle and pump shaft, the described pump housing and
Seal receptacle is all set on pump shaft, and it also includes stationary ring, rotating ring, rotating ring gland, flies ferrum and mechanical seal,
Described stationary ring is located in the pump housing, and described rotating ring gland is located between the pump housing and seal receptacle, and described rotating ring is located at
In rotating ring gland, one end of described rotating ring is inconsistent with stationary ring, and its other end passes through mechanical seal and sealing
Seat is inconsistent, described in fly Tie Tong and cross bearing pin and be connected to the outside of rotating ring gland.
Further, described mechanical seal includes sealing ring and spring, and described sealing ring is inconsistent with rotating ring,
Described spring is located between sealing ring and seal receptacle.
Further, being provided with the first bulge loop outside the middle part of described stationary ring, described rotating ring contacts with stationary ring
One side be provided with the second bulge loop.
Compared with prior art, the beneficial effects of the utility model are: on the one hand this utility model uses
The sealing of stationary ring and rotating ring is superimposed with mechanical seal, makes sealing property more preferable, on the other hand flies setting of ferrum
Meter, when pump operation, the centrifugal force flying ferrum generation makes the spring-compressed of mechanical seal by rotating ring gland,
Cause rotating ring to disengage with stationary ring, make mechanical seal play a role, and when pump is out of service, rotating ring is with quiet
The contact surface of ring extrudes mutually, and mechanical seal simultaneously works as effect with the sealing of stationary ring and rotating ring.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, below will
The accompanying drawing used required in embodiment or description of the prior art is briefly described, it should be apparent that,
Accompanying drawing in describing below is only embodiments more of the present utility model, for ordinary skill people
From the point of view of Yuan, on the premise of not paying creative work, it is also possible to obtain the attached of other according to these accompanying drawings
Figure.
Fig. 1 is the structural representation of high-chromium wear-resistant alloy ore pulp transh pump of the present utility model.
Description of reference numerals: 1, the pump housing, 2, stationary ring, 3, rotating ring, 4, rotating ring gland, 5, fly ferrum,
6, seal receptacle, 7, sealing ring, 8, spring, 9, pump shaft.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that this practicality is new
The advantage of type and feature can be easier to be readily appreciated by one skilled in the art, thus to protection of the present utility model
Scope makes apparent clear and definite defining.
Refering to shown in Fig. 1, this utility model provides a kind of high-chromium wear-resistant alloy ore pulp transh pump, including pump
Body 1, seal receptacle 6 and pump shaft 9, the described pump housing 1 and seal receptacle 6 be all set on pump shaft 9, and it also wraps
Including stationary ring 2, rotating ring 3, rotating ring gland 4, fly ferrum 5 and mechanical seal, described stationary ring 2 is located at the pump housing 1
In, described rotating ring gland 4 is located between the pump housing 1 and seal receptacle 6, and described rotating ring 3 is located at rotating ring gland 4
In, one end of described rotating ring 3 is inconsistent with stationary ring 2, and its other end is by mechanical seal and seal receptacle 6
Inconsistent, described in fly ferrum 5 and be connected to the outside of rotating ring gland 4 by bearing pin.
Concrete, mechanical seal described in this utility model includes sealing ring 7 and spring 8, described sealing ring
7 is inconsistent with rotating ring 3, and described spring 8 is located between sealing ring 7 and seal receptacle 6.
Concrete, it is provided with the first bulge loop, the first bulge loop outside the middle part of stationary ring 2 described in this utility model
Stationary ring 2 can be avoided to produce axial float, the one side that described rotating ring 3 contacts with stationary ring 2 after mounting
It is provided with the second bulge loop.Second bulge loop can reduce the contact area of rotating ring 3 and stationary ring 2, improves extruding force.
Design principle of the present utility model is: on the one hand use stationary ring and the sealing of rotating ring and mechanical seal
Superimposed, make sealing property more preferable, on the other hand fly the design of ferrum, when pump operation, fly what ferrum produced
Centrifugal force makes the spring-compressed of mechanical seal by rotating ring gland, causes rotating ring to disengage with stationary ring, makes machinery
Sealing plays a role, and when pump is out of service, rotating ring and the contact surface of stationary ring extrude mutually, mechanical seal
Sealing with stationary ring and rotating ring simultaneously works as effect.
Above-described embodiment is this utility model preferably embodiment, but embodiment of the present utility model is also
