Abstract

The invention discloses a leakless submerged pump with a detachable rotary device, comprising a pump body (9), a pump cover (7), a motor base (1), an oil chamber (6), an impeller (8), a shaft (11) and a bearing body (2). The motor base (1) is arranged above the bearing body (2) and the oil chamber (6) is arranged below the bearing body (2); a bearing sleeve (10) and a shaft sleeve (12) are sleeved at the upper section of the shaft in the position of the bearing body (2); a bearing (4) is arranged on the bearing sleeve (10); a lower bearing (5) is arranged at the lower shoulder of the shaft sleeve (12); and an upper bearing end cover (3) and a lower bearing end cover (13) are respectively sleeved on the shaft (11) and fixed with the bearing body (2). According to the structure adopted by the invention, the main shaft does not need to be pulled out from the pump body during the overhauling and only the shaft sleeve is dismantled with convenient operation, therefore, the manpower and material resources are saved, the labor intensity of the worker is reduced and the efficiency is improved.

Description

Have the nothing that to shirk slewing gear and leak Under Water Pumps

Technical field

The present invention relates to pump structure under a kind of no leakage fluid, especially relate to a kind of nothing leakage Under Water Pumps that can shirk slewing gear that has.

Background technique

Under Water Pumps is mainly used in industrial and mining enterprise such as water utility, sewage treatment works, power plant, Iron And Steel Plant, mine, and in municipal plumbing, field irrigation, the engineering such as control flood and drain flooded fields.The Under Water Pumps pump housing is submerged in the medium, is applicable to the usefulness that contains a large amount of particle slurry in the medium, also can be used on other viscosity and is lower than in the 300CP chemical-process to carry and has corrosive solid viscosity liquid that contains.At present, the main shaft of Under Water Pumps adopts integral shaft mostly, and promptly main shaft connects with motor shaft by coupling, and the bearing in the bearing support directly is sleeved on the main shaft, though easy to assembly like this, make troubles to maintenance.All need during maintenance main shaft is extracted out in the pump housing, owing to be subjected to the long structural limitations of length of main shaft, main shaft is unloaded down from motor shaft at every turn, even main shaft to be slit into two sections, part on the motor shaft could be unloaded down with general utility tool, each maintenance is all wanted so to have wasted manpower, material, maintenance is extremely inconvenient, has reduced working efficiency.

Summary of the invention

The purpose of this invention is to provide a kind of nothing leakage Under Water Pumps that can shirk slewing gear that has, can solve not have and leak the inconvenient technical problem of Under Water Pumps maintenance.

The problem that will solve required for the present invention realizes by the following technical solutions: it comprises the pump housing, pump cover, motor cabinet, grease chamber, impeller, axle and bearing support, motor cabinet is installed in the bearing support top, the grease chamber is installed in the bearing support below, it is characterized in that: segmented sheathing has bearing housing and axle sleeve on the axle in described bearing support position, install bearing on the bearing housing, lower bearing is installed at shoulder place, axle sleeve lower end, top bearing cover and lower bearing end cap be set on the axle and with the fastening installation of bearing support.

The structure that the present invention adopts does not need during maintenance main shaft is extracted out from the pump housing, only needs the axle sleeve dismounting, and is easy to operate, saved manpower and materials, reduced working strength of workers, improved efficient.

Description of drawings

The present invention is described further below in conjunction with accompanying drawing:

Accompanying drawing is depicted as structural representation of the present invention

Among the figure 1, motor cabinet 2, bearing support 3, top bearing cover 4, upper bearing (metal) 5, lower bearing 6, grease chamber 7, pump cover 8, impeller 9, the pump housing 10, bearing housing 11, axle 12, axle sleeve 13, lower bearing end cap

Embodiment

By accompanying drawing as can be known, this has the nothing leakage Under Water Pumps that can shirk slewing gear and comprises the pump housing 9, pump cover 7, motor cabinet 1, grease chamber 6, impeller 8, axle 11 and bearing support 2, motor cabinet 1 is installed in bearing support 2 tops, grease chamber 6 is installed in bearing support 2 belows, segmented sheathing has bearing housing 10 and axle sleeve 12 on the axle in described bearing support 2 positions, install bearing 4 on the bearing housing 10, lower bearing 5 is installed at shoulder place, axle sleeve 12 lower end, top bearing cover 3 and lower bearing end cap 13 be set on the axle 11 and with bearing support 2 fastening installations.

When needs overhaul, perhaps need to change if any parts, axle can be extracted out, only need from top to down preface dismounting successively, motor cabinet 1, bearing housing 10, upper bearing (metal) 4 and bearing support 2 and axle sleeve 12, lower bearing 5 are pulled down, just can be realized maintenance, simple to operation.

Obviously, the above embodiment of the present invention only is for example of the present invention clearly is described, and is not to be qualification to embodiments of the present invention.For those of ordinary skill in the field, can also make other multi-form variation or changes on the basis of the above description.Here need not also can't give all mode of executions exhaustive, and these belong to conspicuous variation or the change that spirit of the present invention draws and still are among protection scope of the present invention.

Claims

1. one kind has the nothing leakage Under Water Pumps that can shirk slewing gear, comprise the pump housing, pump cover, motor cabinet, grease chamber, impeller, axle and bearing support, motor cabinet is installed in the bearing support top, the grease chamber is installed in the bearing support below, it is characterized in that: segmented sheathing has bearing housing and axle sleeve on the axle in described bearing support position, install bearing on the bearing housing, lower bearing is installed at shoulder place, axle sleeve lower end, top bearing cover and lower bearing end cap be set on the axle and with the fastening installation of bearing support.
