One , the use
The ZJ20's set bearing heating apparatus is chiefly used to the bearing and the gear and even shaft length and much kinds of forms metal spares heat the railroad engine wheel mind and tyre and so on , causes swells , is filled with fitting either necessaries that disassemble in order to have meeied .

Two , the produce type reaches such sense

Three , the strong point
Possess a lot of bearings to be living in the installation process to injure , and heats the means unsuitably to be one of significant reason . In case adoping the burn together means to heat , be able to create the bearing to become deformed ; Adoping the flame to heat , the bearing both sides is heated not to be diveded evenly ; Adoping the oil bath to heat , the gathering is as a result of the not clean bearing the causing pollution of oil character , and the buzz broadens ; Adopt the oven to heat , and exceedingly costs time . As to raing the installation , the bearing is altered to accept the harm .
Now the freshest technique is emploing ZJ20's reaction heating apparatus , and such strong point is :
The length electricity 90% length oil 100% being economical practise thrift the factory building covering an area of area 70%
The work efficiency is liftd over 4 -fold when saving , and operation personnel staff decrease 80%
Dependablely heat uniformly , it is perfectly clean , being favour of lifing the fitting quality ;
The security does not there is not fire alarm peril most ;
The oil petrol pollution air is not there is not in the environmental protection , and is favour of the body health of environment improvement and work personnel staff .

Four , composition together with the work rule
The composition ZJ20 set bearing heating apparatus consists of workman's frequency reaction heating unit ( below abbreviation leader ) of the style work since cools together with dominates installation . ZJ20X and ZJ20T act as the mobile composition , else all fiing style composition in the interest of admittedly .

Five , the work rule
1 , the transformer that the leader is one particular composition is heated in the short circuit , and the yoke iron that may be removed is used for directly puting on the suit bearing either else are heated the work . When work , the connection leader power source , reaction coming into being short circuit electric current but is heated in the work ( balancees pair ) along the coil .
2 , whirling fluid is heated the unalterable rush pith work together with leader makes up one closed magnetism return , and when doing by means of the leader magnetic line of force comes into being whirling fluid but by in the work heating speedily .

ZJ20X's set bearing heating apparatus

Main technique parameter The main technique parameter is catch sight of that the table unalterable standard of 1 yoke catchs sight of the table 2 .

Table 1

Table 2

Fix debug
1 , lay up yoke iron on unalterable rush pith of the leader end face .
2 , whether unanimously examineing the wiring against the jack of plug , grounding ought to be well , afterwards possess plug sticking in on the control switch convenience receptacle .
3 , pokeeing the meritorous service capacity option switch up the hand control place , going up the power source together , at this moment the red pilot lamp shines .
4 , according to the start button , the leader is energize , at this moment the green pilot lamp shines , and the revolutionary light extinguishes ; According to ceaseeing the push-button , the revolutionary light shines , and the green light extinguishes . Up to this point , debugs the end , yet put in the use .

Operation sequence
Chooseing relevant yoke iron ( catching sight of the table 2 ) , the yoke iron that interlinks the bearing shall pay a visit to is lay up on the unalterable rush pith end face of leader the 1 , inside diameter on the basis of the bearing , and it is straight and even to coincide .
2 , in being living to heat the process , Wen Ji surveys and encircles fairing part temperature rise inner place the bearing use spot . Accords with the demand when temperature rise , sees surely time bears in mind the figure , in immediate future ceases to heat , and moves turning on yoke iron , and takes off the bearing fiing together .
3 , continuously heats the identical standard bearing , by the meritorous service capacity option switch pokes up hour the charge place , fixes warm-up period , serves as the bearing by the heating up buildding up time in immediate future shuts the blackout source voluntarily .
4 , queen is completeed in the work , and pokeeing the meritorous service capacity option switch up ceaseeing the place , and cutting off the place .

ZJ20K's set fast heating apparatus of gear

The main technique parameter of main technique fast heating apparatus of parameter is catch sight of the table 3 .
Table 3

Fix debug
1 , control box and leader are fixed up the appropriate space separately . The leader is masterred the orientation ought to the level , and the vertical orientation permits to slope not to be more than 3 degrees backward altogether .
2 , queen is completeed in the installation , and is living before the use have to check according to the electric schematic diagram , whether the wiring impedees .
Going up button , power hook-up together , the voltmeter ought to possess the instruction to 3 , right errorless queen now .
4 , is heated the work lays up up maneuver yoke iron of unalterable pistil middle of the leader next , and removes down gently , if causing it coincide against the work ( the work thickness dimensions is unchangeable , may regulate the leader queen's heaver bridge next set screw , causes yoke iron together with work maintain the clearance of 2mm , in order to make things convenient for the consecutive operation ) . Up to this point , debugs the end , yet put in the use .

Operation sequence
1 , according to the start button , the leader is energize , time the relay starts bearing in mind the figure , the unit act as second , the work is heated .
2 , according to ceases before the push-button , sees surely time bears in mind the figure , brings out the work immediately , and surveys whether such inside diameter fairing part temperature rise accords with the demand , in order that suit packing .
3 , continuously heats the identical standard work , by the meritorous service capacity option switch pokes up hour the charge place , fixes warm-up period , serves as the work by the heating up buildding up time in immediate future shuts the blackout source voluntarily .
4 , queen is completeed in the work , and pokes the power-fail up ceases place , dump .

Pay attention to matter
Shell grounding have to be well !
The ZJ20X does not lay up yoke iron and ZJ20K and does not lay up before the work , and strictly forbids according to the start button .
This the set produce control power source act as the wiring against the plug of AC220V either AC380V jack ought to the correspondence unanimously .
ZJ20X's use ought to be lay up smooth and steadyly , and yoke iron coincide against the leader end face .
The bearing is heated that the temperature rise does not overtake 120 s , in order to provide against softening ; Else work is the supremelyest heated the temperature rise is not more than 300 s .

Special type of heating apparatus
That ZJ20T's 55 , 67 and 97 set is encircled inner place the bearing disassembles use .
ZJ20B's railroad engine tyre and the ins turn mind and driven gear temperature loads and unloads use .
Heave-duty inflexible temperature is fitd together and piece may be consulted and follow the use .
The gear on the manufacture pipleline such as diesel engine , motor vehicle and tractor and so on is heated , and the welcome is engaged by special arrangement placeing an order for .
