The daily care and maintenance of transducer reachs his to overhaul the job

S.

The power source of T) . 2, affirmatory transducer power source is cut off, show after disappearing, when after indicator light of internal high tension goes out, just carry out safeguard, examination. 3, in check out procedure, cannot reach wire with will inner power source absolutely, platoon line uproots reach match by accident, can cause transducer not to work otherwise or damage. 4, the fittings such as the screw when installation cannot place stays in transducer interior, lest circuit board creates short circuit appearance. 5, what transducer maintains after installation is clean, avoid dust, oily mist, damp is invaded. Transducer inspects an item regularly 1, power source voltage affirms accord with transducer place to need voltage; (Special the place that notices whether power supply cord and motor have damaged) layout terminal and connector, whether to become loose; (Whether to have in power supply cord and terminal) 2, whether does transducer interior have dirt, export electricity, output frequency (the quantity gives a result its difference cannot too big) 3, whether is the temperature all round the examination - between ℃ of 5 ℃ ~ 40, installation environment is drafty; 4, humidity: Maintain in 90% the following; (The appearance that cannot have knot water) 5, there is as good as in movement constant sound or unusually oscillatory phenomenon; (Transducer cannot the place with park great vibration) 6, blowhole is done regularly please sweep the job. Of spare parts change transducer is comprised by a variety of components, after permanent worker of classics of component of wh some of which is made, its function can be reduced gradually, ageing, this also is the main reason that transducer malfunctions, to assure the normal movement with long-term facility, following parts of an apparatus should change regularly: (The power module of 1) cooling fan transducer is it is calorific the most serious parts of an apparatus, its work continuously the quantity of heat of a generation must want seasonable eduction, the life of general fan is 10kh~40kh about. By transducer successive moving convert is 2~3 year be about to change fan, direct cooling fan has second line and the branch of 3 lines, second line fan among them a gleam of is positive electrode, another line is negative line, the fault is not received when changing; 3 lines fan besides, there still is line of a check outside negative pole, the ten million when changing notices, can cause transducer overheat to call the police otherwise. Communication fan is the cent of 220V, 380V commonly, grade of the voltage when changing does not make a mistake. (Dc answers capacitance of road filter wave among capacitance of 2) filter wave: Say to electroanalysis again capacitance, its main effect is flowing volts d.c. , absorb the low frequency harmonic in dc, the quantity of heat that the quantity of heat that its successive job produces adds transducer itself to arise meets those who accelerate its electrolyte to dry up, affect the size of its capacity directly. Normal circumstance issues the service life of capacitance to be 5 years or so. The proposal examines capacitance capacity every year regularly, general its capacity reduces 20% above to should change new filter wave capacitor. Maintain regularly remove dust regularly whether is examination fan air inlet blocked up dead, sweep inhaler refrigeration air channel and in-house dirt every months. Regular examination, answer one year to undertake: Examination screw, bolt and namely plug-in unit whether to become loose, whether do pair of ground that input output reactor and alternate with resistor have short circuit appearance, should be more than a few Europe normally. Whether do conductor and dielectric have corrode a phenomenon, if have,should wipe in time clean with alcohol. Measure switch power source to output the smooth stability of each circuit voltage, be like: The voltage such as 5V, 12V, 15V, 24V. Whether does the contact of contactor have mark of strike a light, what want badly to change to be the same as model or be more than original size is new taste contactor; Affirm the validity that controls voltage, undertake the movement experiments be protectived orderly; Affirm protection shows loop as good as constant; Affirm the balance that voltage outputs when transducer is moving alone is spent. The daily care and maintenance that does good transducer seriously reachs his to overhaul the job, content basically includes: (1) undertakes removing dust to transducer regularly, the key is rectification ark, inversion ark and control ark, can mix rectification module, inversion module when necessary the circuitry inside control ark board tear open a junior travel to remove dust. The air inlet below transducer, go up an a place with a draught whether dirt retention or because dirt retention is overmuch and jam. Transducer comes loose because of itself hot demand ventilation is big, after reason runs proper time, exterior dirt retention is very serious, need fixed cleanness to remove dust. (2) opens transducer front door, back door ravels, microscope is handed in, dc mother platoon has without be out of shape, corrode, oxidation, platoon joint screw has the mother to be taken off without the pine, each installation secures a dot to be in solid screw to have take off without the pine, fixed with insulation piece or insulation column has do not have ageing craze or be out of shape, if have,should change in time, originally closely afresh, discharge to already producing metabolic mother reinstall after the beard is corrective. (3) is right platoon of circuit board, mother after removing dust, undertake necessary anticorrosive processing, besmear brushs insulating varnish, to already appearing the partial discharge, mother platoon that pulls arc needs purify after its burr, undertake handling again. To already was isolated from the insulation of puncture board, beard purify its attaint part, in what corresponding insulation social estate uses near its attaint insulation board undertakes isolating handling to its, originally closely and think qualification is rear can throw use. (The fan inside 4) commutate ark, inversion ark moves it is normal to reach roll, stop when machine, with hand roll, observation bearing has die without card or murmur, change when necessary bearing or maintenance. (5) reachs inversion, dc to input fast frit to have comprehensive examination to input, commutate, discover burn down changes in time. (The capacitor in dc loop has the liquid that do not have leakage among 6) , crust has without expand, rouse bubble or be out of shape, relief valve whether burst, conditional can wait to capacitance capacity, leakage current, compression have a test, undertake changing to according with the capacitance of the requirement, to new electric capacity or capacitance of long-term and unused untapped, the beard before changing undertakes to its passivation is handled. The use cycle of filter wave capacitance is 5 years commonly, be in to using time 5 years of above, mark of apparent deviate check follows the index such as capacitance capacity, leakage current, compression, should part of take into consideration the circumstances or change entirely. (7) uses avometer to undertake to the diode of part of rectification, inversion, GTO electric detect, determine its to, retrorse resistance, make good record seriously inside the form that has made beforehand, see each extremely block value is normal, the consistency of parts of an apparatus of same type is good, undertake changing when necessary. (8) presents line cabinet to A1, A2 inside advocate contactor and other assist contactor to undertake checking, observe each contactor activity touchs a head to have carefully without pull arc, burr or exterior oxidation, uneven, discover this kind of problem answers its corresponding activity to touch a head to undertake changing, ensure its contact on the safe side. (Microscope terminal platoon has 9) to be taken off without ageing, pine, whether to put in short circuit recessive breakdown, each jumper link is firm, line skin has without damaged, each circuit board plug is received insert firm. Pass in and out advocate join of power supply cord is reliable, joint has wait for a phenomenon without calorific oxidation, ground connection is good. (10) reactor has as good as to often bleat, vibration or burnt flavour. Article origin: Shenzhen city beauty overcomes Inc. of energy science and technology CNC Milling
