Description
Affiliated technical field
The utility model relates to fluid machinery, relates in particular to a kind of elastometric lining heavy type slurry pump of novel sheath sealing configuration.
Background technique
Heavy elastometric lining slag stock pump is a kind of horizontal centrifugal double-shell pump, and frame is metal ceramic, and inner housing is removable rubber flow passage part, and inner housing flow passage part is generally comprised of front and back backplate and front and back sheath.Heavy type slurry pump is mainly used in grinding machine discharging pulp conveying, the cyclone separator Gei Kuangdeng workshop section in ore-dressing technique on mine, and fed sheet of a media is the slurry that contains solid particle, and ore pulp has that particle is large, concentration high, and flow passage part and sheath seal inefficacy easy to wear.
At present, the sheath sealing configuration of heavy type slurry pump as shown in Figure 3, between sheath and backplate, sealing adopts a lip seal, its working principle is in the high-pressure liquid inflow lip seal part by slag stock pump inner chamber, because the effect of pressure is expanded two lips of Sealing outwardly, compress with the rubber on sheath backplate surface, reach the effect of sealing.The maximum inferior position of this kind of seal action is to need slag stock pump inner high voltage fluid to enter in lip seal part, and fluid in heavy type slurry pump normally contains the slurry of solid particle, this produces destruction by the surface of contact between sheath and backplate and lip seal part, has influence on the working life of sheath backplate and lip seal part.
Summary of the invention
The problem existing for solving above-mentioned sealing configuration, the novel elastometric lining heavy type slurry pump that a kind of novel sheath sealing configuration is provided of this use, solve the problem of heavy type slurry pump sheath backplate and the inefficacy easy to wear of lip seal part, improve rubber sheath backplate working life.
The utility model solves the technological scheme that its technical problem adopts:
The elastometric lining heavy type slurry pump of novel sheath sealing configuration, by bracket, rear backplate, the pump housing, rear sheath, front sheath, pump cover, apron plate, impeller etc., formed, the elastometric lining heavy type slurry pump that it is characterized in that described novel sheath sealing configuration, sheath sealing has adopted two seals structure.
Described two seals structure, the backplate seal ring being provided with on the face contacting with sheath at rubber backplate, backplate seal ring and backplate are made of one, and form first sealing, prevent that particle from entering in sealing surface.
Described two seals structure, rubber backplate is provided with L-type lip.
Described two seals structure, rubber sheath is provided with boss face, forms second sealing with the L-type lip of backplate, and when first seal failure, whole sealing configuration is still normally worked.
Compared with prior art; the beneficial effects of the utility model are the working life of improving rubber sheath backplate; reduce and shut down the number of times of changing; sealing configuration and sheath backplate are made of one; do not need independent seal element; also need on pump housing pump cover, not offer the processing groove of placing lip seal part, overall structure is simple.

Fig. 2 is the novel sheath sealing configuration partial enlarged drawing in Fig. 1;
Fig. 3 is the schematic diagram of prior art sheath sealing configuration;
In figure: 1. bracket, 2. rear backplate, the 3. pump housing, 4. rear sheath, 5. front sheath, 6. pump cover, 7. apron plate, 8. impeller, 9. boss face, 10.L type lip, 11. backplate seal rings, 12. lip seal parts.
Embodiment
For technological means, character of innovation that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, the elastometric lining heavy type slurry pump of novel sheath sealing configuration, by bracket (1), rear backplate (2), the pump housing (3), rear sheath (4), front sheath (5), pump cover (6), apron plate (7), impeller (8) etc., formed, between sheath and backplate, adopt two seals structure.
As shown in Figure 2, apron plate (7) is consistent with the sealing configuration between front sheath (5), rear sheath (4) and rear backplate (2), in figure, to take apron plate (7) and front sheath (5) novel sealing structure be example to enlarged view, on the face contacting with front sheath (5) at apron plate (7), be provided with the apron plate seal ring (11) of four circles, backplate seal ring (11) is made of one with apron plate (7), the sealing of formation first, can effectively prevent that particle from entering in sealing surface, effectively improve working life simultaneously.
As shown in Figure 2, front sheath is provided with boss face (9) and forms second sealing with the upper L-type lip (10) of apron plate (7), and when first seal failure, whole sealing configuration is still normally worked.
Claims (3)
1. the elastometric lining heavy type slurry pump of novel sheath sealing configuration, by bracket (1), rear backplate (2), the pump housing (3), rear sheath (4), front sheath (5), pump cover (6), apron plate (7), impeller (8) etc., formed, it is characterized in that: between sheath and backplate, adopt two seals structure.
2. according to the elastometric lining heavy type slurry pump of novel sheath sealing configuration claimed in claim 1, it is characterised in that: the face that rubber backplate contacts with sheath is provided with backplate seal ring (11), backplate seal ring (11) is made of one with backplate, the sealing of formation first, prevents that particle from entering in sealing surface.
3. according to the elastometric lining heavy type slurry pump of novel sheath sealing configuration claimed in claim 1, it is characterized in that: rubber backplate is provided with L-type lip (10), rubber sheath is provided with boss face (9), form second sealing with the L-type lip (10) of backplate, when first seal failure, whole sealing configuration is still normally worked.
