Abstract
Present invention mainly discloses a kind of dual-gripper impeller pump interrupter, including driving shaft, driven shaft, be cased with bearing, sealing device, rotor on driving shaft and driven shaft the most successively, pump housing cover is combined in outside rotor.One of improvement of the present invention is to be, on driving shaft and driven shaft, outside framework oil seal is all used to isolate between bearing and sealing device, bearing is separated with sealing device, rotor, medium, form separate cavities, it is unlikely to have working media, when leaking, bearing is caused damage, bearing is individually lubricated simultaneously, form independent lubricating chamber.
Description
Technical field
The present invention relates to impeller pump technical field, the most relevant with the interrupter on a kind of dual-gripper impeller pump.
Background technology
In recent years, Environmental protection work is increasingly paid attention to, and sewage disposal industry has obtained quickly developing, and increasing rapidly of sewage treatment capacity brings increasing sharply of sludge yield.According to investigation, mud produced by wastewater treatment in China factory, 80% is had not dealt carefully with, mud is arbitrarily stacked the produced pollution and has been highlighted with recontamination problem, cause the extensive concern of society, in order to thoroughly solve this problem, environmental administration requires that " water " " mud " must run simultaneously process.At present, impeller pump has become process sewage, the indispensable visual plant of mud, but impeller pump both domestic and external all uses single supporting construction, and not only stability is bad, can not be high pressure resistant, although have has a dual-support structure, but the pump housing chamber of pumped (conveying) medium and the bearing bore unreasonable structure that is arranged on pump cover, when carrying sewage sludge, can be blocked between seal and axle, make sealing surface wear, cause dielectric leakage, so that corrosion bearing.In order to well protect the bearing of dual-gripper pump cover, preventing pumped (conveying) medium, dust, pollutant etc. from entering, this case thus produces.
Summary of the invention
Invention broadly provides the interrupter of a kind of dual-gripper impeller pump, employing outside framework oil seal is arranged, dual-gripper impeller pump upper bearing (metal) is separated with sealing device, rotor, medium, form separate cavities, it is unlikely to have working media, when leaking, bearing is caused damage, bearing is individually lubricated simultaneously, form independent lubricating chamber.
To achieve these goals, the technical solution used in the present invention is:
A kind of dual-gripper impeller pump interrupter, including driving shaft, driven shaft, is cased with bearing, sealing device, rotor on driving shaft and driven shaft the most successively, and pump housing cover is combined in outside rotor；One of improvement of the present invention is to be: on driving shaft and driven shaft, all uses outside framework oil seal to isolate between bearing and sealing device.
Described outside framework oil seal installation position on driving shaft and driven shaft is provided with anti-wear sleeve.
The described pump housing includes pump case and pump cover, and rotor is positioned in the chamber formed after pump case and pump cover fastening, after pump cover end cap and cover plate fasten, is fixed on outside pump cover.
Described bearing and outside framework oil seal are positioned in pump cover end cap, and region residing for outside framework oil seal separates bearing and sealing device, form separate cavities, offer leaking medium tap hole below separate cavities.
Pump cover end lubricating cavity is offered into and out of oilhole on described cover plate.
After using technique scheme, the present invention arranges outside framework oil seal, can be by dual-gripper impeller pump upper bearing (metal), separate with dual-gripper impeller pump upper sealing device, rotor, medium etc., form separate cavities, below separate cavities, it is provided with leaking medium tap hole, effectively prevents working media from leaking the damage that bearing is caused.The present invention is dual-gripper impeller pump, its good stability, and high voltage performance is strong.
It addition, bearing has independent lubricating cavity, and it is provided with into and out of oilhole, it is also possible to check the oil level in lubricating cavity at any time, simple to operate.
Accompanying drawing explanation
Fig. 1 is the structural representation of present pre-ferred embodiments；
Wherein label declaration: driving shaft 1, driven shaft 2, bearing 3, sealing device 4, rotor 5, the pump housing 6, pump cover 7, outside framework oil seal 8, pump cover end cap 9, cover plate 10, separate cavities 11, axle sleeve 12, leaking medium tap hole 13, pump cover end lubricating cavity fuel feed hole 14, pump cover end lubricating cavity oil outlet 15.
Detailed description of the invention
In conjunction with accompanying drawing, present pre-ferred embodiments is described in further details.
The present embodiment is dual-gripper impeller pump, including driving shaft 1, driven shaft 2, twin shaft dual-support structure, there is good stability and barotolerance.
Driving shaft 1, the parallel laying of driven shaft 2, be cased with bearing 3, sealing device 4 and rotor 5 the most successively.Owing to this part-structure is identical, therefore the present embodiment is specifically illustrated as a example by the structure on driven shaft 2.
In the chambers that rotor 5 is formed after being in the pump housing 6 and pump cover 7 fastening more, the position that the pump housing 6 contacts with driven shaft 2 with pump cover 7 is provided with sealing device 4.In dual-gripper impeller pump real work, it is impossible to accomplish working media zero leakage, therefore the key of the present invention is through outside framework oil seal 8 and will isolate between sealing device 4 and bearing 3.
In the present embodiment, bearing 3 is between pump cover end cap 9 and cover plate 10, after pump cover end cap 9 and cover plate 10 fasten, is fixed by screws on pump cover 7.Beginning with the region for mounting framework oil sealing 8 on pump cover end cap 9, so bearing 3 and sealing device 4 are separated, the region that outside framework oil seal 8 is positioned at forms separate cavities 11.Simultaneously in order to prevent the abrasion of driven shaft 2, outside framework oil seal 8 installation position arranges axle sleeve 12 as anti-wear sleeve.
Offer leaking medium tap hole 13 in the lower section of separate cavities 11 to communicate therewith; so when dual-gripper impeller pump is in course of conveying; if working media leaks from sealing device 4; directly flowed out by leaking medium tap hole 13; effectively preventing working media from entering in the lubricating cavity of bearing 3, adequately protected bearing 3.
It addition, observe the lubricating oil in bearing 3 lubricating cavity for convenience, cover plate 10 is offered pump cover end lubricating cavity fuel feed hole 14, pump cover end lubricating cavity oil outlet 15.
The present embodiment is not limited to above-mentioned act, all changes utilizing this design that the present invention carries out unsubstantiality, all should fall into protection scope of the present invention.
