Abstract
The utility model discloses a rusting preventive device for a fan of a cooling tower. The rusting preventive device is a cap, and the cap covers an impeller shaft, a hub mandrel, a gland and a compression bolt, and is hermetically and integrally connected with a hub plate by a connecting bolt and a threaded hole on the hub plate. The rusting preventive cap made of glass fiber reinforced plastics is arranged on the hub plate, so that moisture can be effectively prevented from 'rusting' an impeller mandrel hole, the compression bolt and threads via a screw hole and a gap on the gland of the impeller shaft, the problem that an impeller and the impeller shaft are separated difficultly when the fan is repaired is solved easily, and the rusting preventive device is low in manufacturing cost.
Description
[technical field]
The utility model belongs to the blower fan of cooling tower technical field, is specifically related to a kind of blower fan of cooling tower anti-corrosion device.
[background technique]
Blower fan of cooling tower is worked in extreme moist environment usually, and each exposed part is very easy to corrosion, even " rust is dead "; Especially impeller shaft and cooperation place, wheel hub mandrel hole and gland compressing structure are exposed outside; " rust is dead " especially easily is in case " rust is dead " just can't be dismantled during maintenance.In this case, can only cut, so not only waste time and energy, also waste material increases the cost of overhaul, therefore is necessary to make improvements.
[model utility content]
The technical problem that the utility model solves provides a kind of blower fan of cooling tower anti-corrosion device; On boss plate, be provided with the cover cap of processing with glass fibre reinforced plastics; With gland, gland bolt, impeller shaft and the wheel hub mandrel escutcheon that is mated; Thoroughly stop steam and see through gland screw gap entering impeller shaft and wheel hub mandrel hole, prevent that effectively corrosion or rust " extremely " phenomenon from taking place, the problem of impeller shaft and wheel hub mandrel hole partition difficulty when easily solving the blower fan repairing.
In order to solve the problems of the technologies described above; The technological scheme that the utility model adopts is: blower fan of cooling tower anti-corrosion device; Said anti-corrosion device is the cover cap; Said cover calotte and will cover cap and boss plate through the tapped hole on connecting bolt and the boss plate and be tightly connected and be one above impeller shaft, wheel hub mandrel, gland and hold-down bolt.
Wherein, said cover cap is made up of the flanging that comprises the lower end, and place, said flanging lower end surface is shaped on seal groove, is shaped on bolt hole on the flanging.
Further, said seal groove is inverted U, is provided with seal ring in it.
Further, said cover cap is whole processes with corrosion resistant glass fibre reinforced plastics.
The utility model is compared with prior art through being provided with anti-corrosion glass steel cage cap on boss plate; " become rusty bead filler axis hole and hold-down bolt, screw thread extremely " in the screw gap that can avoid steam to see through on the impeller shaft gland, the problem of impeller and impeller shaft partition difficulty when easily solving the blower fan repairing.

[embodiment]
The embodiment of the utility model is described below in conjunction with accompanying drawing.
Blower fan of cooling tower anti-corrosion device, said anti-corrosion device is processed for cover cap 1, the corrosion resistant glass fibre reinforced plastics of cover cap 1 usefulness; Said cover cap 1 is made up of the flanging that comprises the lower end 2 integral body; Place, said flanging 2 lower end surfaces is shaped on seal groove 6, and said seal groove 6 is inverted U, is provided with seal ring 7 in it.Be shaped on bolt hole 3 on the flanging 2; Said cover cap 1 covers on impeller shaft 8, wheel hub mandrel 9, gland 11 and hold-down bolt 12 tops; And will cover cap 1 and boss plate 10 through connecting bolt 4 and tapped hole 5 on the boss plate 10 and be tightly connected and be one; Constitute the brand new of impeller shaft 8 and boss plate 10 compressing structure anti-corrosions, reach the purpose of anti-corrosion.
Glass steel cage cap 1 is the anticorrosion part of a kind of brand-new blower fan of cooling tower; The gland 11 screw gaps that can avoid steam to see through on the impeller shaft 8 are dead with gland bolt 12 rust with impeller shaft 8 and wheel hub mandrel hole 9, the difficulty of impeller shaft 8 and 9 partition of wheel hub mandrel hole when easily solving the blower fan repairing.
The above in the spiritual category that does not break away from the utility model creation, is familiar with the protection domain that this technological various simple covert and modification that those skilled in the art did still belongs to the utility model only in order to the convenient the utility model of explaining.
