Villatic elevator gets extensively our love, after be being installed high-end air, bitter fleabane wall is brilliant, but if encounter the problem of a few breakdown, so of its breakdown what to eliminate train of thought and method to have? Silent accept overcomes villatic elevator manufacturer to explain for you!
Elevator is by machinery, procrastinate move loop, electric control to be comprised partly. Procrastinate move a system to also can belong to electrical system, consequently the breakdown of villatic elevator can be divided for mechanical failure and electric breakdown. When encountering trouble, should decide breakdown belongs to which system above all, it is mechanical system or electrical system, decide breakdown is which one part that attributes which system again next, judge breakdown out again then at which on the contact of component or which action part.

The breakdown out that how judges villatic elevator which system? The method that uses generally is: Above all buy elevator at " the overhaul " working status, a position is made the same score in car (in computer room, litter top or car are operated) the dot moves elevator to go up slow or slow come down to decide.
Install to ensure complete, should affirm all shaft door must have closed to be in entirely above all overhaul in moving, must not open again! Go up below overhaul condition because of elevator or be issued to lower levels, electric control circuit is the simplest point uses circuit, pushbutton presses how long, elevator runs how long, do not press pushbutton elevator won't movement, need runs how many distance to be able to be controlled at will, speed very slow, car traversal speed is less than 0.63m/s, so safer, facilitating overhaul personnel is operated and search breakdown place to belong to place, this is the elevator function that installs to overhaul personnel only. Electric return circuit is done not have other intermediate control segment, it controls elevator to procrastinate directly use a system, elevator overhauls personnel in overhauling moving process but subtle observation has as good as constant sound, off-odour, certain directive signal is normal wait. Elevator dot is moved it is normal to move to want only, can affirm: Main and mechanical system is no problem, in electrical system advocate procrastinate move loop to do not have a problem, the breakdown control with respect to out electrical system in circuit. Cannot nod conversely move elevator to move, breakdown the mechanical system with respect to out elevator or advocate procrastinate use circuit. The dot is moved in moving if affirm advocate procrastinate move circuit to have trouble, namely advocate loop has trouble, you are OK from form advocate each link of loop go analysing breakdown to be in place. The A.C.-D.C.power supply loop of any electric machinery, include the control circuit of all sorts of functions, must form what communication or dc electric current flow to close loop, electric current is broken by block in place of the any in loop or billabong, can cause trouble, the place that electric current is judged by block is in place with respect to hereat barrier, answer to affirm itself of power supply source is normal above all of course, do not have electric current otherwise or voltaic size is improper, this also is different period appears easily one of place of breakdown. Make any elevator advocate the basic link of loop is roughly same: Set out from power source of power supply three-phase classics air switch, go up or contactor of communication of be issued to lower levels, governor, moving contactor, hot relay, final make return circuit of three-phase alternating current to winding of electric machinery three-phase. Different to method of timing of different type elevator, the type of governor is different also, nothing more than it is frequency control, communication pressure regulating timing, dc is pressure regulating timing or soft starter, of course the electromotor of form a complete set is not identical also. Advocate loop breakdown also is common breakdown mixes elevator with main trouble.

Procrastinate because of giving priority to using a system is discontinuous discontinuous often movement, after consequently elevator moves a few years, contactor contact often has exhaustion of shrapnel of oxidation, contact, contact undesirable, contact falls off, inversion module reachs thermal breakdown of silicon controlled rectifier or burn, machine bearing grinds report bad to wait for breakdown. This is one of train of thought that look for breakdown quickly, because any mechanical action parts have certain life, be like relay, contactor, micro-gap switch, journey switch, the component such as pushbutton, still have the part that often runs, for instance the travelling cable of car, often curve a movement, have the possibility of line breakdown with respect to existence.
