Abstract
The utility model relates to a heating device for a bearing and a bearing pedestal of a wind generating set. The heating device comprises an intermediate frequency heater and an intermediate frequency heating zone. A water supply pipeline and a water drainage pipeline are connected on the intermediate frequency heater. A water pump is disposed on the water supply pipeline. The intermediate frequency heating zone is wound on an inner ring of the bearing pedestal and is fixed through a clamping tool. An end portion of the intermediate frequency heating zone is connected on the intermediate frequency heater. A heat insulation material is laid between the intermediate frequency heating zone and the inner ring of the bearing pedestal. The heating device is more reasonable in design and rapid and safe in heating, is convenient to use, exhibits fine heating effects, and is especially suitable for heating a bearing and a bearing pedestal of an extra-large wind generating set. The heating device helps to solve problems that the bearing and the bearing pedestal of the wind generating set are difficult to heat, enables a main shaft system to be assembled easier and more conveniently and to be simple to operate, and helps to provide great guarantee for research and development of a more larger wind generating set.
Description
Technical field
The utility model relates to a kind of heater, particularly a kind of wind turbine generator bearing, bearing pedestal heater.
Background technology
Along with the development of new forms of energy industry,, in electrical network, occupied increasing proportion as exploitation wind energy early in the new forms of energy.In order more effectively to improve the efficient of utilizing wind energy, maximization of wind-powered electricity generation unit and specialized trend are very obvious, and the appearance of homemade 6MW wind-powered electricity generation unit has shown the manufacturing capacity of homemade blower fan to the world, and is indicating the operation climax of a homemade ultra-large type blower fan new round.Yet; Increase along with single-machine capacity; Corresponding bearing, bearing pedestal also increase accordingly, and bearing pedestal is integrated with mainframe, the huge difficulty of bringing to the bearing arrangement hot charging; And the irreversible especially step of axis system hot charging, in case the failure that error will cause whole blower fan to be installed.At present; The bearing of blower fan and the mode of heating of bearing pedestal have multiple; Mainly comprise electric hot plate heating, electric furnace heating, electromagnetic induction heating method, the oil groove heating, these several kinds of mode of heatings all respectively have the characteristics of oneself; But the heating of bearing pedestal in the time of all can't heating bigger bearing and bearing pedestal, particularly bearing pedestal and mainframe and be integrated.So be badly in need of a kind of bearing, bearing pedestal heater that can satisfy ultra-large type blower fan generating set of design at present.
Summary of the invention
The utility model technical problem to be solved is the deficiency to prior art, provides that a kind of structure is more reasonable, cost is low, easy to use, firing rate also can heat the bearing of ultra-large type blower fan and the heater of bearing pedestal soon.
The utility model technical problem to be solved is to realize through following technical scheme.The utility model is a kind of wind turbine generator bearing and bearing pedestal heater, is characterized in: this heater comprises intermediate frequency heater and heating in medium frequency band; On intermediate frequency heater, be connected with supply channel and discharge pipe line, on supply channel, be provided with water pump; Described heating in medium frequency band is wrapped on the inner ring of bearing pedestal and through jig and fixes, and the end of heating in medium frequency band is connected on the intermediate frequency heater, between the inner ring of heating in medium frequency band and bearing pedestal, is equipped with insulation material.
In described wind turbine generator bearing of the utility model and the bearing pedestal heater technical scheme, further optimized technical scheme or technical characterictic are:
1, described insulation material is preferably heat-preservation cotton.
2, described jig is preferably column, evenly is arranged on the inner ring of bearing pedestal.
3, described jig is preferably the bakelite jig.
Water pump described in the utility model extracts water and gets in intermediate frequency heater and the heating in medium frequency band through supply channel, and it is cooled off, and provides stable hydraulic pressure and flow to guarantee that intermediate frequency heater normally moves.Intermediate frequency heater can be supplied power by the 380V power supply; In the middle of heating tape and heated parts, increased insulation material; Guarantee that bearing or bearing pedestal temperature are difficult for leaving, also prevent that the heating tape from leaning against the metal surface of heat and damaging the heating tape simultaneously, described jig is fixed on the heating in medium frequency band on the bearing pedestal inner ring; Jig selects nonmetallic materials to process, and intermediate frequency heater does not heat jig in the use.
Compared with prior art, the utility model wind turbine generator bearing and bearing pedestal heater structural design are more reasonable, heat fast, safe, easy to use, and heats is good, are specially adapted to bearing, the bearing pedestal heating of ultra-large type wind turbine generator.The utility model solves the problem of the difficult heating of ultra-large type wind turbine generator bearing, bearing pedestal, makes simple more, convenient, the operation easily of axis system assembling, for from now on more the Large-scale Wind Turbines research and development sound assurance is provided.
