Description
Technical field
The utility model relates to a kind of portable device that pastes reflective sheeting on rotor.
Background technique
Along with the continuous increase of steam turbine generator pool-size, the subsidiary engine capacity that steam turbine and boiler use is also in continuous increase, when the vibration of subsidiary engine occurs when abnormal, will carrying out vibration-testing to it.A lot of subsidiary engines all do not have system of condition monitoring, can only scene set up vibration monitoring equipment Vibration Condition is monitored.But subsidiary engine is in running state while setting up vibration monitoring equipment, if want to determine that vibration cause must read vibration frequency feature, the extraction of vibration frequency feature need to have tach signal just passable.Under normal circumstances, the measurement of rotating speed need to, by paste reflective sheeting on rotor, utilize photoelectric velocity measurement equipment to read.But because subsidiary engine is in running state, rotor speed at least operates in 500 revs/min, rotating speed is higher, cannot directly paste reflective sheeting, can only first subsidiary engine be stopped in this case, after reflective sheeting is sticked, start subsidiary engine, cause like this cost high, and inefficiency.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of portable device that pastes reflective sheeting on rotor, and it is not only easy to carry, and reduces subsidiary engine start and stop process, reduces costs, and increases work efficiency.
The technical solution adopted in the utility model is as follows:
The utility model comprises a DC micro-motor, is fixedly installed on the roller on motor shaft and is arranged on the reflective sheeting on roller, described roller is provided with the buckle for fixing reflective sheeting, on described motor, be fixedly installed handle, described handle is provided with circuit and the sliding button for controlling motor.
Good effect of the present utility model is as follows: the utility model provides a kind of device that can paste to subsidiary engine rotor reflective sheeting under rotation situation; it is not in the situation that affecting subsidiary engine work; reach the object of pasting reflective sheeting; reduce the start and stop process of subsidiary engine; not only save time; and reduced cost, greatly improve the efficiency of carrying out high-speed balancing test, for the on-line monitoring of subsidiary engine in rotation situation provides possibility.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is the utility model roller structure schematic diagram;
Accompanying drawing 3 is circuit theory diagrams of the present utility model.
In the accompanying drawings: 1 motor, 2 rollers, 3 reflective sheetings, 4 buckles, 5 handles, 6 motor shafts.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As accompanying drawing 1, shown in 2, the present embodiment comprises DC micro-motor 1, be fixedly installed on the roller 2 on motor shaft 6 and be arranged on the reflective sheeting 3 on roller 2, described roller 2 is provided with the buckle 4 for fixing reflective sheeting 3, to ensure that in rotary course, reflective sheeting 3 can not come off, described reflective sheeting 3 side outwardly has certain viscosity, can stick on the surface of subsidiary engine rotor, on described motor 1, be fixedly installed handle 5, described handle 5 is provided with circuit and the sliding button for controlling motor, described circuit comprises a dryelement cell, LM317 stabilized power supply integrated package, a fixed value resistance and a variable resistor.The voltage of described dryelement cell is 9v, the DC motor speed regulating that passes through of use is all realized with adjustment supply voltage without exception at present, but directly use variable resistor speed governing, just must bear enough power, therefore the utility model by using LM317 stabilized power supply integrated package to carry out speed governing in circuit.
As shown in Figure 3, dryelement cell, for LM317 stabilized power supply integrated package provides a stable input voltage V, passes through LM317 stabilized power supply integrated package, a low power variable resistor R
2, a low power fixed value resistance R
1, obtain a variable output voltage V
out, the output terminal of output voltage connects motor, and for motor provides a different voltage, the utility model circuit is simple, by the button on sliding handle, changes the resistance in circuit, and then changes output voltage, reaches the object that regulates motor speed.The middle-size and small-size direct current generator of the utility model is used for providing continuous rotating speed for connected roller.
In the utility model, the formula of output voltage is as follows:
V
out=1.25V（1+R
2/R

adjfor the electric current of 1 pin output in LM317.
It is known that the utility model utilizes the rotating speed v1 of subsidiary engine equipment and radius r 1, and the radius r 2 of the motor roller of model utility equipment is known, and formula v1*r1=v2*r2 can try to achieve the rotating speed v2 of model utility equipment.In such cases, two rotating objects when contact tangential velocities are identical and in the same way, now two rotating objects, in relative static conditions, can be pasted reflective sheeting on rotor.
Working principle of the present utility model: calculate v2 by formula, after being fixed on to motor roller, reflective sheeting regulates variable-frequency motor, test the speed and display device can be known the rotating speed that variable-frequency motor is exported by existing, in the time that rotating speed is shown as v2, make the slowly arbitrary position of close subsidiary engine rotor of roller.At this moment,, because a reflective sheeting side outwardly has certain viscosity, can stick on subsidiary engine rotor surface.
The utility model belongs to special purpose device, for pasting reflective sheeting on the rotor being in operation, is applicable to mostly need to carry out rotating equipment the work of vibration-testing.Use this device to solve when operating rotating machinery is carried out to vibration-testing, cannot be on the rotor of rotation the difficult problem of label adhering reflective sheeting.
This device has fully utilized in two rotating object movement processes, and in the time meeting v1*r1=v2*r2, when two rotating objects are in contact with one another, its tangent direction velocity magnitude equal direction is identical, in relatively static state, is achieved apparatus function.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments of making within the spirit and principles in the present invention, be equal to and replace and improvement etc., within being all included in protection scope of the present invention.
