Pump body assembly has contained bearing cover, has been equipped with the bearing retainer of a lubrication points, two bearings in the axle, bearing retainer, the one set of mechanical seal, the pump body that contains eccentric internal diameter, concentric installation's contain groove rotor, circumference radially imbed a plurality of gleitbretters in the rotor draw -in groove and hold the pump cover after, level with both hands. The utility model discloses owing to change bearing position and put, move the back end bearing to the front end, form unilateral duplex bearing cantilever type structure, reduced the use of mechanical seal, bearing to change gleitbretter, rotor convenience, improved maintenance efficiency greatly, reduced the technical ability requirement to maintainer, bearing retainer just can locate, the anti - mechanical seal of dress, the lubrication points becomes one by two, and it is capacious to pour into the grease into, has prolonged the life of mechanical seal and bearing, realizes the high efficiency and the energy -conservation nature of pump.
Description
Technical field
The utility model relates to the sliding vane pump for carrying various grease, chemical medium, particularly a kind of cantilever detachable type sliding vane pump.
Background technique
Sliding vane pump is a kind of common positive displacement pump, have other self-priming time not available for pump class short, suck the high performance of vacuum pressure.Be mainly used in the operating mode of all handling liquid such as train, liquid harbour, oil tanker, tank car, chemicals tank switching.It mainly comprises motor, coupling, pump housing assembly.Current existing sliding vane pump, all adopt bearings at both ends supporting structure, successively by the bearing of front and back bearings gland, front and back pump housing end cap, both sides end cap and sealing, with one heart install containing eccentric internal diameter stator, install with one heart embed multiple slide plate in rotor draw-in groove forming containing groove rotor, axle, circumference radial direction.When slide plate, rotor failure need to change, rear side bearing gland, rear side pump housing end cap, mechanical seal, bearing, axle need be removed, slide plate, rotor can be changed.The mounting or dismounting of this structure, cleaning, safeguard complicated, single maintenance time is long, and cost is high, and requiring that attendant must possess must professional skill, does not therefore meet high efficiency and energy saving.There are two lubricating points before and after the pump housing, inject grease capacity constraint, add loaded down with trivial details, change outer lubricating mechanical sealing difficulty.
Summary of the invention
For improving high efficiency and the energy saving of pump, the utility model proposes a kind of cantilever detachable type sliding vane pump.
The utility model comprises motor, coupling, pump housing assembly, pump housing assembly contain containing two bearings (9) in the pump housing (1) of eccentric internal diameter, bearing gland (7), the bearing bracket (5) being provided with a lubricating point (10), axle (6), bearing bracket (5), a set of mechanical seal (8), be coaxially arranged in the pump housing (1) embed containing groove rotor (2), circumference radial direction multiple slide plates (4) in rotor (2) draw-in groove, after hold pump cover (3) level with both hands.
The technical solution of the utility model is according to cantilever type pump structure, described axle (6) is arranged in bearing (9), two bearings (9) are arranged in the bearing bracket (5) that is connected with the pump housing (1) front end simultaneously, the pump housing (1) is connected with bearing bracket (5) that part is positive and negative fills a set of mechanical seal (8), for active chamber (11) and the lubricating cavity (12) of separate pump, bearing bracket (5) place establishes a lubricating point (10), and a flat pump cover (3) is installed in the pump housing (1) rear end.
The utility model has the following advantages: 1, owing to changing bearing (9) position: rear end bearing (9) is moved to bearing bracket (5) place, form one-sided duplex bearing cantilever structure, eliminate rear robot sealing (8), the use of bearing (9), the mounting or dismounting of this structure are simple, convenient, the flat pump cover (3) of the pump housing (1) rear end is opened, without the need to dismounting mechanical seal (8), axle (6), bearing (9), both replaceable slide plate (4), rotor (2), thus greatly save mounting or dismounting, cleaning, maintenance time, improve maintenance efficiency, reduce the skill set requirements to attendant, 2, bearing bracket (5) place can be different according to conveying liquid, positive and negative dress mechanical seal (8), thus can carry the liquid of poor lubricity, improve the practicability of pump, 3, bearing bracket (5) waist is provided with a lubricating point (10), and lubricant grease smooth and easyly can pass through the working surface that lubricating cavity (12) enters bearing (9) and mechanical seal (8), greatly extends its working life, 4, lubricating point (10), mechanical seal (8), bearing gland (7), flat pump cover (3) become one by two, and simplify the operation step, saves production cost, and realizes high efficiency and the energy saving of sliding vane pump.
Accompanying drawing explanation
Fig. 1 is the pump housing assembly sectional drawing of the utility model cantilever detachable type sliding vane pump.
Fig. 2 is the pump housing assembly axis side view of the utility model cantilever detachable type sliding vane pump.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
See accompanying drawing 1, accompanying drawing 2, a kind of cantilever detachable type sliding vane pump, it comprises motor, coupling, pump housing assembly.Pump housing assembly contain containing two bearings (9) in the pump housing (1) of eccentric internal diameter, bearing gland (7), the bearing bracket (5) being provided with a lubricating point (10), axle (6), bearing bracket (5), a set of mechanical seal (8), be coaxially arranged in the pump housing (1) embed containing groove rotor (2), circumference radial direction multiple slide plates (4) in rotor (2) draw-in groove, after hold pump cover (3) level with both hands.Described two bearings (9) are arranged on simultaneously in the bearing bracket (5) be connected with the pump housing (1) front end, form one-sided duplex bearing (9) cantilever structure, when slide plate (4), rotor (2) damage and need to change, the flat pump cover (3) of the pump housing (1) rear end is opened, without the need to dismounting bearing (9), mechanical seal (8), axle (6), i.e. replaceable slide plate (4), rotor (2), thus greatly save mounting or dismounting, cleaning, maintenance time, improve maintenance efficiency, reduce the skill set requirements to attendant; Active chamber (11) and the lubricating cavity (12) of a set of positive and negative dress mechanical seal (8) for separate pump are installed, lubricating point becomes one by two, lubricating cavity (12) cavity at bearing bracket (5) place is large, lubricant oil can be kept for a long time to mechanical seal (8), bearing (9) working surface, extend the working life of mechanical seal (8) and bearing (9).
