Abstract
A kind of Pulp pump improved structure of wear-resistant sheath, including inner sheath, rear backplate and O-ring seal, its main feature is that, the Pulp pump improved structure of wear-resistant sheath is positioned by the cylindrical fit hole of inner sheath and rear backplate, it is mounted in the Pulp pump pump housing behind the inner sheath and the cylindrical fit hole of the Pulp pump pump housing and the cylindrical fit hole positioning of Pulp pump pump cover, accurate positioning during assembling, the gap uniformity of wear-resistance protective sleeve and impeller blade after assembling, without adjustment, fully meet product design and performance requirement, employing cylindrical hole cooperation simultaneously is easily guaranteed that workmanship, and the O-ring seal of mating use also correspondingly reduces manufacture cost.The configuration of the present invention is simple enables wear-resistance protective sleeve to be accurately positioned and effectively seal, improves Pulp pump use reliability, effectively reduce production cost.
Description
Technical field
The present invention relates to a kind of Pulp pump, particularly a kind of Pulp pump of high leakproofness.
Background technology
Pulp pump in industrial circle use than wide, with the corresponding Structural Development technology of Pulp pump also always into
Row, but there are some insufficient problems in structure in engineering use in present Pulp pump product, as shown in Figure 1, Pulp pump
Wear-resistance protective sleeve in structure is made of inner sheath 01 and rear backplate 02, and passes through the inner sheath 01 and the cone of rear backplate 02
It is risen in the pump housing 03 after degree cooperation, radially without positioning requirements during assembling, wear-resistance protective sleeve component is easy to because of oneself in assembling process
It drops again, the gap for leading to wear-resistance protective sleeve and back blade is uneven, and sealing effect is poor, adjustment is inconvenient, the big gesture of error
Overall performance must be influenced, shortens wear-resistance protective sleeve service life, increases maintenance cost, while employs taper fit and also increases to manufacture
Difficulty and the special sealing ring of mating use 04 is added also to correspondingly increase manufacture cost, because the special sealing ring 04 will
It buys on the market, also expends energy and time cost.
Invention content
To solve the above problems, An embodiment provides a kind of Pulp pump of high leakproofness, including interior shield
Set, rear backplate and O-ring seal, the wear-resistance protective sleeve are inner sheath and rear backplate composition, its main feature is that, the Pulp pump is with resistance to
Mill sheath improved structure is positioned by the cylindrical fit hole of the inner sheath and rear backplate, the inner sheath and the Pulp pump pump housing
Cylindrical fit hole and Pulp pump pump cover the positioning of cylindrical fit hole after in the Pulp pump pump housing.
Due to there is cylindrical surface (hole) positioning assembling between inner sheath, rear backplate and the pump housing, pump cover, so accurate positioning,
It ensure that the gap uniformity of wear-resistance protective sleeve and back blade after assembling, do not need to any adjustment, product design can be met and made
It with performance requirement, while employs cylindrical surface (hole) cooperation substitution circular conical surface (hole) and coordinates, be easily guaranteed that workmanship, and energy
The O-ring seal substitution special sealing ring for improving production efficiency and mating use also correspondingly reduces manufacture cost.
The invention has the advantages that solve the accurate positionin and effectively sealing of Pulp pump wear-resistance protective sleeve, perfect production
Product structure improves the use reliability of Pulp pump, reduces production cost, improves economic benefit.
Description of the drawings
Fig. 1 is the structure diagram of the wear-resistance protective sleeve in existing Pulp pump；
Fig. 2 is the structure diagram of the Pulp pump of the present invention.
Specific embodiment
Fig. 1 is the structure diagram of the wear-resistance protective sleeve in existing Pulp pump.Fig. 2 is that the structure of the Pulp pump of the present invention is shown
It is intended to.Referring to Fig. 1, wear-resistance protective sleeve is made of inner sheath 01 and rear backplate 02 in existing slurry pump configuration, the wear-resisting shield
Set is by being risen in the pump housing 03 after the taper fit of inner sheath 01 and rear backplate 02, radially without positioning requirements, dress during assembling
It is easy to drop because of dead weight with wear-resistance protective sleeve component in the process, the gap for leading to wear-resistance protective sleeve and back blade is uneven, adjusts
Whole inconvenience, error is big certainly will to influence Pulp pump overall performance, shorten the service life of wear-resistance protective sleeve, also intangibly increase
Maintenance cost；It is also also corresponding to the special sealing ring 04 of manufacture increase difficulty and mating use that taper fit is employed simultaneously
Ground increases manufacturing cost.
To change some defects existing for existing Pulp pump wear-resistance protective sleeve structure, to improve Pulp pump overall performance,
Wear-resistance protective sleeve is enable to be accurately positioned and effectively seal, reduce production cost and is increased economic efficiency.Pulp pump of the present invention is with resistance to
Mill sheath improved structure efficiently solves the problems, such as this, its specific embodiment is as described below：
Referring to Fig. 2, Pulp pump improved structure of wear-resistant sheath of the present invention, including inner sheath 1, rear backplate 2 and O-ring seal
3, its main feature is that, the improved structure of wear-resistant sheath is positioned by inner sheath 1 and the cylindrical fit hole A of rear backplate 2, described interior
It is mounted in the pump housing after sheath 1 and the cylindrical fit hole positioning of the cylindrical fit hole B and pump cover of the Pulp pump pump housing 4.Due to inner sheath
1st, there is cylindrical surface (hole) positioning assembling between rear backplate 2 and the pump housing 4, pump cover, so accurate positioning, ensure that wear-resisting after assembling
The gap uniformity of sheath and back blade does not need to any adjustment so that wear-resistance protective sleeve can be sealed effectively, can meet product
Design and use performance requirement；Cylindrical surface (hole) cooperation substitution circular conical surface (hole) is employed simultaneously to coordinate, and reduces technology difficulty,
It is easier to ensure that workmanship, and production efficiency can be improved.Replaced in above-mentioned cylindrical surface matching hole using the O-ring seal
Special sealing ring also correspondingly reduces manufacture cost.
Basic principle, main feature and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, various changes and improvements may be made to the invention without departing from the spirit and scope of the present invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent defines.
