Abstract
The utility model relates to components of a hanging-type trash remover, in particular to an underwater pulley shaft of a hanging-type trash remover. The pulley shaft comprises a copper pulley outer sleeve (1) and a nylon pulley inner sleeve (2), wherein the nylon pulley inner sleeve (2) is tightly sleeved with the copper pulley outer sleeve (1); seal grooves, close to the two ends of the nylon pulley inner sleeve (2) are formed in the inner wall of the nylon pulley inner sleeve (2); and seal rings (4) are mounted in the seal grooves (3). The pulley shaft has the effects that the seal grooves, close to the two ends of the nylon pulley inner sleeve, are formed in the inner wall of the nylon pulley inner sleeve, so that the silt in water is efficiently prevented from getting into the pulley shaft; and the pulley inner sleeve is made of nylon, so that in the situation of not affecting normal operation, the force of friction between the pulley inner sleeve and a slide bar, the working efficiency is improved, and the service life is prolonged.
Description
Technical field
The utility model relates to suspension type sewage-cleaning machine component, is specifically related to a kind of suspension type sewage-cleaning machine pulley spindle under water.
Background technique
Sewage-cleaning machine, general removing drainage and irrigation station, water power plant, the heat power station recirculated cooling water pump of being used for.The pulley spindle under water of existing suspension type sewage-cleaning machine, mainly overlap in the pulley overcoat of being made by cast copper and the pulley and constitute, the inner wall smooth of cover in the wherein said pulley, and do not have sealing and arrange, silt in the water enters the interior cover of pulley of pulley spindle easily in use, pulley spindle is caused serious wearing and tearing, serious reduction of service life; Whole pulley spindle all is that the cast copper that adopts is made in addition, and the frictional force in its pulley between cover and the slide bar is excessive, has influenced working efficiency and the working life of suspension type sewage-cleaning machine.
The model utility content
The purpose of this utility model is to provide a kind of suspension type sewage-cleaning machine pulley spindle under water, having solved the pulley spindle under water that is used for the suspension type sewage-cleaning machine in the prior art, to enter in silt and the pulley frictional force between the cover and slide bar easily excessive, influences the working efficiency of suspension type sewage-cleaning machine and the problem in working life.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
A kind of suspension type sewage-cleaning machine is pulley spindle under water, comprise cover in casting in bronze pulley overcoat and the nylon pulley, being locked in the described nylon pulley is enclosed within the casting in bronze pulley overcoat, and the inwall of cover is provided with seal groove near the place, two ends in the described nylon pulley, in the described seal groove seal ring is installed.
Further technological scheme is that above-mentioned seal ring is the O RunddichtringO.
Further technological scheme be above-mentioned seal groove with it in the close nylon pulley cover end distance be 12mm.
Further technological scheme is that the degree of depth of above-mentioned seal groove is 4.3mm～4.8mm.
Compared with prior art, the beneficial effects of the utility model are: the inwall that overlaps in nylon pulley is provided with seal groove near the place, two ends, effectively silt enters in the pulley spindle in the block water, and cover adopts nylon to be made in the pulley, under the situation that does not influence proper functioning, reduced the frictional force between the interior cover of pulley and the slide bar, improved working efficiency, obtained working life prolonging.
