Description
Technical field
The invention belongs to hydraulic generator set thrust bearing force bearing adjustment technical field, especially a kind of hydraulic generator set thrust bearing force bearing adjustment specific purpose tool.
Background technology
The weight of whole hydro-turbo generator set rotary part and the axial hydraulic thrust of the hydraulic turbine are born in the effect of hydraulic generator set thrust bearing, and these power are passed to loading frame and the base concrete of hydrogenerator.It is one of most important ingredient of Hydraulic Power Unit, and the quality of its serviceability will be directly connected to the safety and stability of unit, can be described as " heart " of unit.
The force bearing adjustment of thrust bearing, belong to an important process content in unit axis adjustment work, its Main Function qualifiedly (namely meets generator amature and stator center in main-shaft axis adjustment, the error requirements of rotary wheel of water turbine center and fixing seal ring centres) basis on, the height of the anti-heavy bolt of each thrust bearing shoe of further adjustment, to make each thrust bearing shoe uniform force, thus ensure that the oil film thickness of thrust bearing each bearing shell in unit operation is even, the good running status that bearing shell has a narrow range of temperature, this is also one of essential condition meeting unit safety stable operation.
When carrying out force bearing adjustment to thrust bearing, can end user's hammer hit adjustment stressed.When adjusting stressed, need first in each fixing support seat and lockplate, to carry out mark, to check the numerical value risen after bolt rotates.6 ~ 12 pounds of sledgehammers urgent support bolt is equably selected according to unit capacity size.Check lockplate displacement, each support bolt is due to difference of bearing a heavy burden, and the distance of movement is also different, and large displacement of bearing a heavy burden is short, and little displacement of bearing a heavy burden is large.Consider complement one or two hammer on mobile many support bolts.Beat while note the level of runner plate, if find, the undesirable or water place of the leading dial gauge of runner plate level has variation, then should lead in the low orientation of runner plate or water in time and locate dial gauge negative value direction, suitably increase a few hammer, make runner plate maintenance level to support bolt.Repeat to adjust bolt, until the displacement difference of lockplate is no more than 1 ~ 2mm, runner plate level after all support bolt beats one time with same strength, namely think thrust bearing shoe uniform force.
Not high for artificial force bearing adjustment precision, labour intensity is larger, simultaneously higher to operator's skill requirement, be not easy to the shortcoming of carrying out popularization operation, thrust bearing force bearing adjustment specific purpose tool must under the prerequisite meeting force bearing adjustment requirement, increase work efficiency, reduce labour intensity, ensure that the safety of work is carried out.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of structure reliable and stable, design and produce easy, precision is high, be convenient to reading is installed, be applicable to upkeep operation onsite application, the hydraulic generator set thrust bearing force bearing adjustment specific purpose tool of the problem such as simultaneously solve labor intensity of operating staff large, consuming time length, security risk is given prominence to.
The utility model solves the problems of the technologies described above with following technical scheme: hydraulic generator set thrust bearing force bearing adjustment specific purpose tool is made up of measuring staff, dial gauge, dial framework, magnetic force suction base; wherein; it is outside that measuring staff is installed on each toroidal membrane protective cover respectively, and make measuring surface downward.Under every root measuring staff, install two dial gauges, dial gauge gauge head contacts with measuring staff measuring surface upward and perpendicular to measuring staff measuring surface, dial gauge is fixedly connected with equipment Foundations by dial framework and magnetic force suction base.
The utility model uses two dial gauges to carry out force bearing adjustment to toroidal membrane, by gathering each dial gauge reading be installed on dial framework, calculates each toroidal membrane height value; Toroidal membrane fulcrum pin axial displacement is converted into the arc length of adjustment disk by the utility model, to reach the object of adjustment toroidal membrane height, solves the technical matters that the application will solve well.

Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.A kind of hydraulic generator set thrust bearing force bearing adjustment specific purpose tool, comprises measuring staff 1, dial gauge 2, dial framework 3 and magnetic force suction base 4.During use, each toroidal membrane protective cover 8 loaded onto a measuring staff 1 and tightens, and making measuring staff measuring surface level down; Install two dial gauges in the below of every root measuring staff 1, dial gauge gauge head contacts with measuring staff measuring surface and upward perpendicular to measuring staff measuring surface; On every root measuring staff inner side table measuring point to toroidal membrane protective cover distance be 60mm, outside table measuring point to toroidal membrane protective cover apart from be 260mm; On every root measuring staff, two measuring point spacings are consistent and carry out mark; Each dial gauge 2 and dial framework 3 must not encounter toroidal membrane 9 and toroidal membrane protective cover 8.Before measuring, dial gauge adjustment is had certain surplus, that namely shows is little of " 5 ", and greatly for " 0 ", check the dirigibility of dial gauge, inflexible dial gauge must not use simultaneously.When starting to carry out thrust bearing force bearing adjustment, the personnel of Advise By Wire top rotor start high-pressure oil pump jack-up rotor, and when the slow jack-up of rotor is to about 10mm, thrust bearing shoe valve leaves runner plate workplace, when toroidal membrane does not stress that namely all dial gauge readings no longer change, termination of pumping pressurize.Measuring staff place dial gauge is all adjusted again, table little of " 5 ", greatly for " 0 ", check the dirigibility of dial gauge simultaneously.The pressure release of air lock pipeline falls rotor, waits rotor to fall completely after on thrust bearing shoe valve, and recoil air lock, treats that a rear readable all fallen by air lock.Record each measuring staff two meter reading, will notice that when recording the reading of inner side table and outside table will be distinguished, preventing reading from obscuring.By can be calculated compression or the stretch value at this toroidal membrane center.
